1. 2D heat providing device

1 is a view showing a 2D thermal sensation providing apparatus 1 according to an embodiment of the present application.

The 2D thermal sensation providing device 1 according to the embodiment of the present application can provide a thermal experience to the user about the object to be thermally reproduced.

The thermal reproduction object may be defined as an object to be thermally represented by the 2D thermal sensation providing device 1. [ Alternatively, the thermal reproduction object may be defined as an object selected by the user of the 2D thermal sensation providing apparatus 1 for thermal experience.

The 2D thermal sensation providing device 1 may provide a user with a thermal sensation providing stream to thermally represent a thermal regenerative object. The hot feeling providing stream may be defined as a contact surface of the 2D thermal sensation providing device 1 that continuously provides the user with the heat sensation of the thermal object to be reproduced. The hot feeling providing stream may consist of a plurality of hot feeling providing surfaces that are temporally continuous. The hot feeling providing surface may be a contact surface of the 2D hot feeling providing device 1 at one point constituting the hot feeling providing stream. That is, the 2D thermal sensation providing apparatus 1 continuously provides the user with a heat sensation providing surface over time, so that the sensuous heat providing stream is provided to the user, and the user can have a thermal experience with the heat regenerating object.

The 2D thermal sensation providing apparatus 1 can provide a thermosensitivity providing stream and a thermosensitivity providing surface to a user by having a plurality of thermosensitive regions. That is, the user is provided with a feeling of warmth according to the temperature of the 2D thermal sensation providing device 1. [

The heat sensation may include warmth and cold sensation. The heat sensation can be determined based on the user's body temperature. For example, if the temperature of the area of the 2D thermal sensation providing apparatus is relatively higher than the body temperature of the user, the user feels warm in the area, and the user feels cold when the temperature is lower than the reference body temperature. On the other hand, the warm feeling and the cold feeling are different kinds of warm feeling. Hereinafter, the warm feeling and the cold feeling are opposite to each other to express this.

The 2D thermal sensation providing apparatus 1 drives thermoelectric element groups arranged for a plurality of regions and has different temperatures for each region, thereby providing different heat sensations to the users in each region.

Specifically, the 2D thermal sensation providing apparatus 1 may generate different driving power for each region, and provide a heat sensation providing stream or a heat sensation providing surface for providing a different sensation to the user for each region.

As described above, the 2D thermal sensation providing apparatus has different temperatures for different regions and provides different heat sensations to the user, so that the user can experience a vivid thermal experience with respect to the thermal regenerative object. There may be a case where the 2D thermal sensation providing apparatus 1 does not provide the user with a feeling of warmth by region but only provides a certain temperature in the entire region. In this case, the user experiences only one feeling of heat with respect to the object to be thermally reproduced through the 2D hot feeling providing device 1. [ On the other hand, when the temperature is provided for each region, the 2D thermal sensation providing apparatus 1 can provide the user with a sense of thermal sensation regarding the object to be thermally reproduced. Accordingly, the user is provided with various heat sensations in each region, and can experience a vivid thermal experience with respect to the object of heat reproduction.

In this case, the thermoelectric element group 1110 also contacts the base 130, and the heat of the thermoelectric element group 1110 can be reduced by the base 130. Accordingly, it is possible to prevent malfunction of the thermoelectric element group 1110 due to heat accumulated in the thermoelectric element group 1110.

1.1.2 Base

3 is a diagram illustrating an example of a base 130 according to an embodiment of the present application.

The base 130 according to one embodiment of the present application may be disposed between the first substrate 110 and the second substrate 120. The base 130 may be disposed between one surface of the first substrate 110 and one surface of the second substrate 120 facing the first substrate 110. Thus, the base 130 can face the thermoelectric module 1100 disposed on the first substrate 110 and the thermoelectric module 1100 disposed on the second substrate 120, respectively.

On the other hand, on the surface of the base 130 facing the first substrate 110, a member for smoothly receiving heat radiated from the thermoelectric element group 1110 may be disposed.

The base 130 may be disposed in a hot object to reduce the heat of the hot object. In other words, the base 130 is disposed between the first substrate 110 and the second substrate 120 to support both substrates, and can also reduce the heat of the substrate heated at a high temperature. For this purpose, the base 130 may be provided with a heat dissipating member.

The heat dissipating member may receive heat from the object on which the heat dissipating member is disposed and may radiate heat through the heat dissipating member. Thus, the heat of the object can be reduced. For example, when the body 131 is disposed close to the first substrate 110, heat is applied from the first substrate 110 to the first substrate 110, It is possible to reduce heat accumulated in the heat exchanger.

Referring to FIG. 3 (a), the heat dissipation member may include a body 131 and a heat dissipation member 133. However, the heat dissipation member is not limited to FIG. 3 (a), and can be realized by a heat dissipation member including more components than the above-described structure. For example, a predetermined fan may be further implemented in the heat dissipation member.

The body 131 may be a base on which the heat discharging body 133 is formed.

The heat dissipating member 133 may extend from the body 131 to radiate heat of the heat dissipating member.

1.1.3 Support

The support 140 can support the positional relationship of each configuration of the 2D thermal sensation providing device 1. [ For example, the support 140 may support various configurations such that the arrangement relationship of the first substrate 110, the base 130, and the second substrate 120 is maintained.

The support 140 may be disposed on the base 130. The support 140 may have a shape so as to be fastened to the fastening hole 135. The support 140 may have a shape corresponding to the shape of the fastening hole 135.

By providing the support 140, the physical structure of the 2D thermal sensation providing device 1 can be strengthened. In the case where the support 140 is not provided, the respective physical configurations of the 2D heating sensation providing device 1 may be easily shaken by the applied external force and may not be supported by each other, and the arrangement relationship among the components may not be maintained according to the purpose of implementation . On the other hand, since the support 140 is provided in the 2D thermal sensation providing device 1, the arrangement relationship between the physical configurations can be maintained. The support 140 supports the first substrate 110 and the second substrate 120 through the fastening holes 135 formed in the base 130 so that even if an external force is applied to the first substrate 110, 2 substrate 120 and the base 130 can be maintained. Accordingly, the 2D thermal sensation providing device 1 can have the effect of strengthening the physical structure.

In the case where the support member 140 is formed on the first substrate 110 and the second substrate 120 as described above, the support 140 may be provided separately from the support member, Can support. Alternatively, the support 140 may not be provided so that the complexity of the structure in the 2D thermal sensation providing device 1 is reduced.

[ For example, the housing 160 may be provided in a box shape as shown, but may be provided in a coated form without being limited thereto.

In this case, the 2D thermal sensation providing apparatus 1 is provided in a coated form, and can be worn by the user, and allows the user to have a vivid thermal experience with respect to the object to be thermally reproduced through the contact surface of the part worn by the user.

Hereinafter, a thermoelectric drive assembly 1000 implemented in the 2D thermal sensation providing device 1 will be described.

1.2 Thermoelectric drive assembly

The thermoelectric drive assembly 1000 according to one embodiment of the present application may be driven to generate heat or absorb heat. The thermoelectric driving assembly 1000 is driven for each region, so that heat or heat can be absorbed by each region.

The thermoelectric driving assembly 1000 may be disposed on the first substrate 110 and the second substrate 120 of the 2D thermal sensation providing apparatus 1 described above. As the thermoelectric module 1100 disposed in the 2D thermal sensation providing apparatus 1 is driven, the 2D thermal sensation providing apparatus 1 can provide the user with a sense of heat for the thermal regenerative object.

4 is a block diagram of components included in a thermoelectric drive assembly 1000 in accordance with one embodiment of the present application.

Referring to FIG. 4, the thermoelectric driving assembly 1000 may include a driving module 1200 and a thermoelectric module 1100. Without being limited to the components shown in FIG. 4, the thermoelectric drive assembly 1000 may be implemented with a thermoelectric drive assembly 1000 having many more other components. The other components will be described later in detail.

The thermoelectric module 1100 can perform a thermoelectric operation. The thermoelectric operation may include a heating operation and an endothermic operation.

The driving module 1200 may drive the thermoelectric module 1100 so that the thermoelectric module 1100 can perform a thermoelectric operation.

The thermoelectric driving assembly 1000 is driven for each region, so that the 2D thermal sensation providing apparatus 1 can provide a user with different senses of heat related to a thermal recreation target.

Hereinafter, the thermoelectric module 1100 and the driving module 1200, which are components of the thermoelectric driving assembly 1000, will be described in detail.

First, the thermoelectric module 1100 will be described.

1.2.1 Thermoelectric module

The thermoelectric module 1100 according to an embodiment of the present application may perform a thermoelectric operation so that a user is provided with a thermal sensation.

5 is a diagram illustrating a thermoelectric module 1100 disposed on one side of a second substrate 120 according to an embodiment of the present invention.

Referring to FIG. 5, the plurality of thermoelectric element groups 1110 are arranged in a plurality of regions when viewed in a direction perpendicular to the first substrate 110. The plurality of regions may be defined as thermoelectric regions 111 and 113. In other words, the thermoelectric element groups 1110 may be arranged in the thermoelectric conversion regions 111 and 113. For example, the first thermoelectric element group 1111 may be disposed in the first thermoelectric conversion area 111 and the second thermoelectric element group 1113 may be disposed in the second thermoelectric conversion area 113.

The thermoelectric regions 111 and 113 may be defined as divided virtual regions defined on one surface of the first substrate 110 on which the thermoelectric element group 1110 is disposed. Alternatively, the thermoelectric conversion regions 111 and 113 may be defined as respective physical regions of the first substrate 110 on which the respective thermoelectric element groups 1110 are disposed.

As the number of the thermoelectric conversion regions 111 and 113 per unit area of the first substrate 110 on which the thermoelectric element groups 1110 are disposed increases as the number of regions for thermally representing the object to be thermally reproduced increases, It is possible to provide a thermal experience about the objects to be reproduced.

On the other hand, the smaller the area of the thermoelectric conversion areas 111 and 113 than the area of the first substrate 110, the more the thermal resolution can be increased. This is because the area of the thermoelectric conversion elements 111 and 113 is reduced and the number of the thermoelectric conversion elements 111 and 113 is correspondingly increased to increase the number of the thermoelectric conversion element groups 1110 per unit area . In other words, the number of the thermoelectric element groups 1110 disposed per area of the first substrate 110 increases in inverse proportion to the area of the thermoelectric elements 111 and 113.

Hereinafter, the thermoelectric element group 1110 will be described in detail with reference to FIG.

1.2.1.1 Structure and arrangement of thermoelectric group

The thermoelectric element group 1110 includes a first conductor member 1116 disposed on a surface near the base 130 of the adjacent thermoelectric element 1116 for electrically connecting the thermoelectric elements 1116 of the plurality of thermoelectric elements 1116. [ And a second conductor member 1117 disposed on a surface of the thermoelectric element 1116 near the first substrate 110. [ A plurality of first conductor members 1115 are disposed on the vicinity of the base 130 of the plurality of thermoelectric elements 1116. One end and the other end of the first conductor member 1115 are connected to adjacent thermoelectric elements 1115. [ 1116). Likewise, the second conductor member 1117 may be disposed on a surface near the first substrate 110.

The thermoelectric element 1116 may include a first semiconductor and a second semiconductor. The first semiconductor and the second semiconductor may be different semiconductors. For example, the first semiconductor may be an n-type semiconductor, and the second semiconductor may be a p-type semiconductor.

The first conductor member 1115 may be extended by a predetermined distance so that the thermoelectric element group 1110 contacts the driving wire 150. Alternatively, And the driving wire 150 may be in contact with the second conductor member 1117.

The structures of the thermoelectric element groups 1110 arranged in the thermoelectric conversion areas 111 and 113 may be the same. For example, the arrangement relationship of the thermoelectric element 1116, the first conductor member 1115, and the second conductor member 1117 constituting the thermoelectric element group 1110 arranged by thermoelectric conversion areas 111 and 113 is Can be the same.

Alternatively, the structures of the thermoelectric element groups 1110 arranged in the thermoelectric conversion areas 111 and 113 may be different from each other.

Meanwhile, a heat conduction preventing structure for preventing heat conduction between the thermoelectric regions 111 and 113 may be formed between the thermoelectric regions 111 and 113 formed on the first substrate 110, or heat conduction preventing members may be disposed. The thermoelectric regions 111 and 113 may be defined as physical regions of the first substrate 110 on which the respective thermoelectric element groups 1110 are disposed. For example, a line in which the first thermoelectric conversion area 111 and the second thermoelectric conversion area 113 are in contact is conducted to a region where the heat of the first thermoelectric conversion area 111 and the heat of the second thermoelectric conversion area 113 are different from each other A heat conduction preventing structure or a heat conduction preventing member may be formed. This is to provide the user with a clear sense of warmth for each area. As the heat conduction preventing structures or members are formed, heat conduction to different regions can be prevented according to temperatures differently provided to the thermoelectric conversion regions 111 and 113. Accordingly, the phenomenon that the temperatures between the adjacent thermoelectric elements 111 and 113 are mixed with each other is reduced, and a sense of heat can reliably be provided to the user from a region corresponding to the thermoelectric elements 111 and 113.

Alternatively, a structure or member for preventing the thermal conduction is not formed between the thermoelectric conversion regions 111 and 113, or a member for improving thermal conduction may be disposed. In this case, as the heat is conducted between the thermoelectric elements 111 and 113, a temperature gradient may be formed between the corresponding regions. In other words, the temperature between the regions can be changed continuously and formed into a kind of temperature gradation. Accordingly, a user who is provided with a sense of heat through the region can receive a natural, continuous feeling of heat.

1.2.1.2 Thermoelectric behavior of thermoelectric group

The thermoelectric element group 1110 according to one embodiment of the present application can perform thermoelectric conversion. The thermoelectric operation may include a heating operation and an endothermic operation.

The heat generating operation and the heat absorbing operation may be determined according to the polarity of the driving power source I applied to the thermoelectric element group 1110. The driving power source I may include a constant power source P and a reverse power source P having an opposite polarity to the constant power source P. The constant power source P is defined as a power source P for applying a forward current (constant current) and the reverse power source P may be defined as a power source P for applying a reverse current (reverse current) .

The thermoelectric element group 1110 may perform a heat generating operation to induce an exothermic reaction in the direction of the first substrate 110 upon receiving a forward current. The temperature of the first substrate 110 rises to the saturation temperature according to the heating operation, and thus the user is provided with warmth.

The thermoelectric element group 1110 may perform a heat absorbing operation in the direction of the first substrate 110 by receiving a reverse current flowing in the opposite direction of the normal direction. In accordance with the heat absorption operation, the temperature of the first substrate 110 is lowered to the saturation temperature, so that the user is provided with cold feeling.

The thermoelectric action can be controlled for each thermoelectric region. The control of the thermoelectric action may mean the control of the generation of the driving power source I for giving a vivid heat sensation to the object to be thermally reproduced. Specifically, the output of the driving power source I applied to the thermoelectric element group 1110 can be controlled so as to express a region having a warmth and a cold sensation for thermally expressing the object to be thermally reproduced and a degree of warmth and cold sensation have. This will be described later in detail.

1.2.2 Drive module

The driving module 1200 according to an embodiment of the present invention can produce and output a driving power source I for driving the thermoelectric module 1100. The driving power source I may be defined as a power source that is output from the driving module 1200, applied to the thermoelectric module 1100, and driven by the thermoelectric module 1100.

6 is a schematic diagram of a drive module 1200 in accordance with one embodiment of the present application.

6, the driving module 1200 according to an exemplary embodiment of the present invention includes a power generation unit 1210 and a signal generation unit 1230, and the power generation unit 1210 and the signal generation unit A plurality of driving pixels 1201 and 1203 are formed based on a plurality of output lines 1250, 1270 and 1290 output from the driving module 1200. A switch 1300 is disposed in the driving module 1200, The driving power source I output through the driving unit 1300 may be applied to the thermoelectric element group 1110. [

The power generation unit 1210 may output power used for the driving power source I for driving the thermoelectric module 1100.

The signal generator 1230 may output a signal for selecting the thermoelectric element group 1110 to which the driving power P is applied.

The plurality of output lines 1250, 1270, and 1290 may receive power or signals from the power generation unit 1210 and the signal generation unit 1230 and may transmit the power or signal to other configurations.

The switch 1300 may control the characteristics of the power source and the signal. The characteristics may include the magnitude of the power and signal, the waveform of the power and signal, and the period of the power and signal.

The driving module 1200 can output the driving power I to the driving pixels 1201 and 1203 based on the operations of the power generation unit 1210 and the signal generation unit 1230 described above.

The driving pixel may be an area defined by a plurality of output lines (1250, 1270, 1290). The driving pixel includes a data line 1250 of a plurality of data lines 1250, a gate line 1270 of a plurality of gate lines 1270 and a power line 1290 of a plurality of power lines 1290 ). ≪ / RTI > 4, the first driving pixel 1201 is a region defined by a first gate line 1271, a first data line 1251 and a first power line 1291, The driving pixel 1203 is an area defined by the second gate line 1273, the second data line 1253, and the second power line 1293. Specifically, the driving pixels 1201 and 1203 may be regions where electrical signals output from the respective output lines can be simultaneously applied. In other words, the first driving pixel 1201 is an area where electrical signals output from the first gate line 1271, the first data line 1251, and the first power line 1291 can be simultaneously applied, The second driving pixel 1203 may be an area where electrical signals output from the second gate line 1273, the second data line 1253, and the second power line 1293 can be simultaneously applied.

The driving pixel can be interpreted as an area of the electrical concept including configurations that are electrically connected by the output lines or the physical concept area defined by the output lines.

For example, since a plurality of output lines are disposed on one surface of the first substrate 110, a driving pixel may be formed on one surface of the first substrate 110. The driving pixel of the electric concept should be interpreted not only as a configuration to receive a power source P or a signal but also as a concept including a path and an area where the predetermined power source P and a signal are transmitted. For example, the driving pixel may be configured not only to receive the power source P and the signal from the first data line 1251, the first gate line 1271, and the first output line, (P) or various output lines that are provided to transmit a signal.

On the other hand, the driving pixel of the electric concept and the driving pixel of the physical concept are not separate concepts. For example, when one element of the driving module 1200 is defined as the driving pixel of the electric concept, a region where one element is disposed on one surface of the first substrate 110 is also defined as a driving pixel .

Meanwhile, the driving pixel may be a concept corresponding to a pixel in a general optical display.

Hereinafter, the components of the driving module 1200 will be described in detail.

First, the power generator 1210 will be described.

The power of the power source P generated by the power source generating unit 1210 is sufficient to drive the thermoelectric element group 1110. That is, the power generating unit 1210 for driving the thermoelectric element group 1110 is separately provided in the driving unit, so that the thermoelectric element group 1110 is stably driven, It is possible to provide a stable heat providing stream.

7 is a block diagram of a power generating unit 1210 according to an embodiment of the present application.

Referring to FIG. 7, the power generating unit 1210 according to an embodiment of the present application may include a power generating unit 1211, a power adjusting unit 1213, and a power control unit 1215. However, the power generating unit 1210 is not limited to the above-described configuration, and may be implemented as a power generating unit 1210 including more or less configurations.

The power generation unit 1211 may generate and output a power source P. [

The power adjusting unit 1213 may stabilize the power source P. [

The power supply control unit 1215 can control operations of the power generation unit 1211 and the power adjustment unit 1213. [

Hereinafter, each configuration will be described in detail.

First, the power generation unit 1211 will be described.

The thermoelectric module 1100 can be driven based on the power source P output from the power source generating unit 1211. The generated and output power P may be a current. Based on the current, the thermoelectric module 1100 can be driven. The driving of the thermoelectric module 1100 will be described later in detail.

Alternatively, the output power source P may be a voltage. The driving power source (I) may be output from the driving pixel based on the voltage, and the driving power source (I) may be a current.

The power adjusting unit 1213 will be described below.

The power adjusting unit 1213 may be electrically connected to the power generating unit 1211 to stabilize the power source P output from the power generating unit 1211.

The power adjusting unit 1213 receives the power P output from the power generating unit 1211 and stabilizes the power P to output the stabilized power P. The stabilization may mean reducing the size of the power source P or reducing the size of the power source P. [

The power adjusting unit 1213 may be, for example, a regulator. The type of the regulator includes: i) a linear regulator of a type that directly regulates a supplied power supply; and ii) a pulse generator that generates pulses based on the supplied power source, And a switching regulator for outputting a voltage.

The power supply control unit 1215 will be described below.

The power source control unit 1215 can control the characteristics of the power source P output from the power source generation unit 1211. [ The characteristics of the power source may include magnitude and polarity. The power control unit 1215 may be implemented in the power generation unit 1210 but may be separately provided from the power generation unit 1210 to control the operation of the power generation unit 1210.

Such a power control unit 1215 may be implemented as a computer or similar device depending on hardware, software, or a combination thereof. The power supply control unit 1215 may be provided in the form of an electronic circuit such as an MCU, a CPU, a chip, or the like which processes an electrical signal to perform a control function. Or the like.

1.2.2.2 Signal generator

8 is a block diagram showing a signal generator 1230 according to an embodiment of the present application.

9 is a diagram showing an example of a signal output from the signal generator 1230 according to an embodiment of the present application.

8, the signal generator 1230 may include a data signal source 1231, a gate signal source 1233, and a signal control unit 1235.

The data signal source 1231 and the gate signal source 1233 may generate and output a signal for each driving pixel so that the driving power source I is output for each driving pixel. A signal output from the data signal source 1231 may be defined as a data signal DSG and a signal output from the gate signal source 1233 may be defined as a gate signal GSG.

The signal control unit 1235 can control the operation of the data signal source 1231 and the gate signal source 1233. The signal control unit 1235 controls the signal control unit 1235 similarly to the above-described power supply control unit 1215 for controlling the operation of the power generation unit 1211, so redundant description is omitted.

Hereinafter, the data signal DSG and the gate signal GSG will be described with reference to FIG.

The data signal DSG and the gate signal GSG may be signals having an output period and a dormant period. The output interval T may be defined as a time interval over which the signal is output. The idle period t may be defined as a time period during which the signal is not output.

The magnitude and polarity of the signal in the output period may be set according to the purpose of implementation.

For example, in the output period, the data signal DSG may be a first voltage or a second voltage. The first voltage and the second voltage may be different in magnitude from each other, or the polarity of each signal may have a different polarity as a positive voltage and a reverse voltage.

The size of the signal may have a predetermined level. The magnitude of the signal can be controlled by level. The magnitude of the signal may be controlled so as to have a magnitude corresponding to a level at which the magnitude of the signal is selected.

In addition, the data signal DSG and the gate signal GSG may be output during one frame. The data signal DSG and the gate signal GSG output during the frame may be defined as a frame signal.

The frame may be defined as the time until the gate signal GSG is output through all the gate lines 1270 provided in the driving unit. Specifically, when n gate lines 1270 are provided in the driving unit, it may be defined as a time until gate signals GSG are output from all the n gate lines 1270.

The frame may include a plurality of line times (lt). The line time (lt) may be defined as a time for outputting the gate signal GSG through the gate line 1270. Therefore, the gate line 1270 other than the gate line 1270 which is determined to output the gate signal GSG during the line time (lt) can not output the gate signal GSG.

The number of line times (lt) may exist corresponding to the number of gate lines 1270. Specifically, when the gate line 1270 of the driving unit is n, n line times (lt) may exist.

The duration of the above-described frame (frame) and line time (lt) can be appropriately adjusted according to the purpose of implementation.

Although the line time (lt) is described as a time for outputting the gate signal GSG for each gate line 1270, the line time may be defined as a time for outputting a data signal for each data line 1250.

On the other hand, based on the data signal DSG and the gate signal GSG, a driving pixel from which the driving power I is output can be determined. This will be described later in detail.

1.2.2.3 Output Lines

The output line according to one embodiment of the present application may be provided to transmit the power P or signal output from each configuration of the driving module 1200 to another configuration.

The output line includes a plurality of power lines 1290, a plurality of data lines 1250, a plurality of data lines 1250, and a control line 1260, have.

The plurality of power lines 1290 may be defined as output lines output from the power generator 1210.

The plurality of gate lines 1270 may be defined as output lines output from the gate signal source 1233. [

The plurality of data lines 1250 may be defined as output lines output from the data signal source 1231.

The control line 1260 may be defined as an output line that is output from the adjacent switch 1300.

The plurality of branch lines may be defined as output lines output from the above-described lines.

As shown in the figure, the power line 1290, the gate line 1270, and the data line 1250 may be provided in the water channel driving module 1200, but not limited thereto. The number of output lines provided in the driving module 1200 may correspond to the number of thermoelectric conversion areas 111 and 113 of the thermoelectric module 1100. In the case where the thermoelectric region is a 5X5 thermoelectric region, five power lines, a gate line 1270, and a data line 1250 may be provided in the driving module 1200, respectively.

Each output line will be described in detail below.

First, the power line 1290 will be described.

The power line 1290 may electrically connect the power generator 1210 and other components of the driving module 1200. Accordingly, another configuration of the driving module 1200 can receive the power source P generated by the power source generating unit 1210.

The power line 1290 contacts each configuration of the power generation unit 1210 and can receive a power source P for driving the thermoelectric module 1100. The power line 1290 may be in contact with at least one of the power generating unit 1211, the power adjusting unit 1213, or the power control unit 1215 to receive the power source P.

The power line 1290 may be contacted with another configuration of the drive module 1200 such that the applied power source P is delivered to another configuration of the drive module 1200. For example, the power line 1290 may contact the switch 1300 of the drive module 1200 to cause the power source P to be output to the switch 1300.

The gate line 1270 will be described below.

The gate line 1270 may electrically connect the signal generator 1230 and other components of the driving module 1200. Accordingly, another configuration of the driving module 1200 can receive the signal generated by the signal generation unit 1230. [

The gate line 1270 may receive the gate signal GSG from the gate signal source 1233. The data line 1250 may receive the data signal DSG from the data signal source 1231.

The gate line 1270 and the data line 1250 may be contacted with other configurations of the drive module 1200 such that the applied signal is transferred to other configurations of the drive module 1200. For example, the gate line 1270 and the data line 1250 contact the switch 1300 of the driving module 1200 so that the gate signal GSG and the data signal DSG are applied to the switch 1300, As shown in FIG.

The control line 1260 will be described below.

The control line 1260 may electrically connect the adjacent switch 1300. The signal output from the switch 1300 or the power source P may be brought into contact with another switch 1300 so as to be transmitted to the other switch 1300.

Hereinafter, the branch line will be described.

The branch line may extend from a portion of the power line 1290, the gate line 1270, the data line 1250, and the control line 1260 to form a contact with another configuration of the drive module 1200 Or the like. The conductor member may be a wire.

The plurality of branch lines extending from the one line may have an electrically parallel relationship with each other. That is, each branch line extending from the power line 1290 can output the same power source P to each other. Alternatively, each branch line extending from the data line 1250 or the gate line 1270 may output the same signal to each other.

As the branch line is formed in each output line, the present application can have an effect of simplifying the arrangement of each output line.

Meanwhile, the gate line 1270 and the data line 1250 may have different characteristics from the output line. The properties may include physical properties such as thickness and electrical properties such as electrical conductivity, electrical resistance, power supply (P) tolerance.

The different characteristics may result from different electrical signals applied to each output line.

For example, the current or power source P applied to the power line 1290 is much larger than the signal applied to the gate line 1270 and the data line 1250. The allowable power amount of the power line 1290 is larger than the allowable power amount of the gate line 1270 or the power amount of the data line 1250.

Alternatively, the thickness of the power line 1290 may be greater than the thickness of the gate line 1270 or the thickness of the data line 1250. This is because the thickness of the power line 1290 is formed such that the power line 1290 is not ruptured by the power source P applied to the power line 1290 and the gate line 1270 and the data line 1250 do not have to be formed thicker than the power line 1290 because the signal is smaller than the power source P.

The plurality of gate lines 1270, the plurality of data lines 1250, and the plurality of power lines 1290 may extend in one direction. The meaning of extending in one direction should be interpreted to mean not only that the lines extend in a fixed fixed direction but also have a tendency to extend in a certain direction.

At least two of the plurality of gate lines 1270, the plurality of data lines 1250, and the plurality of power lines 1290 may extend and intersect in different directions. For example, when the gate line 1270 extends in a first direction, the data line 1250 may extend in a second direction, and the first direction and the second direction may be different from the gate line 1270 and the data line 1250 may intersect with each other.

At least two of the plurality of gate lines 1270, the plurality of data lines 1250, and the plurality of power lines 1290 may extend so as to cross each other at right angles.

1.2.2.4 Drive control element

The driving control element 1300 according to an embodiment of the present application can control the generation and the output of the driving power source I. [ In other words, the driving control element 1300 may apply the driving power source I to the thermoelectric elements 1110 so that the thermoelectric element groups 1110 arranged for each thermoelectric region perform a thermoelectric operation.

The driving control elements 1300 may be disposed correspondingly to the thermoelectric regions or may be disposed corresponding to the thermoelectric element groups 1110 arranged for each thermoelectric region.

The driving control element 1300 may be disposed for each driving pixel. The driving pixels may be disposed corresponding to each thermoelectric region. The driving control element 1300 arranged for each driving pixel can control generation and output of the driving power I performed for each driving pixel. The control of the driving power source may be based on the power source P applied to the driving control element 1300 and a signal. This will be described later in detail.

The driving control element 1300 is controlled by an applied power P or a signal and the driving control element 1300 can modulate and output the applied power P or signal.

The modulation may include not only changing the characteristics of the applied power P and the signal but also blocking the applied power P and the signal to prevent the power P and the signal from being output.

That is, the modulation may include receiving an applied power (P) and receiving signals, i) output blocking, ii) output shift, iii) output magnitude amplification, and iv) output polarity control.

The cutoff may be defined as outputting or cutting off the power source P or signal applied to the drive control element 1300 depending on whether it is electrically opened or closed.

The shift may be defined as delaying the output of the power source (P) or signal applied to the drive control element 1300. For example, the power source P or signal applied at the first time point may be output at a second time point that is later than the first time point.

The magnitude amplification means amplifying the magnitude of the power source P or signal applied to the driving control element 1300 at a predetermined magnification. The above multiple may be a times, or 1 / a times (where a is not limited to any number).

The output polarity control means that the polarity of the power source P or the signal applied to the driving control element 1300 is controlled and output. The polarity of the power source P or signal output from the driving control element 1300 may be controlled according to a polarity control signal applied to the driving control element 1300.

The drive control element 1300 having the above-described functions may be configured as a device or a module or a unit in which the devices are modularized.

Alternatively, the module or unit may include a chip such as an MCU (Micro Control Unit) capable of performing simple calculations of the devices, a predetermined electronic circuit configured by electrically connecting control elements, and the like.

The drive control element 1300 may include the above-described element, module or unit, and may be implemented as a switch.

The drive control element 1300 operated by the switch may block or output the power source P or signal applied to the switch as the switch is electrically opened and closed by receiving a predetermined signal. In other words, the switch is electrically opened and closed so that the configuration connected to the switch can be electrically short-circuited.

The switch may comprise a gate, an input, and an output.

The switch is capable of receiving a signal (hereinafter referred to as an open / close signal) for determining the electrical opening and closing of the drive control element through the gate, and receives a signal or a power source P through the input terminal, P).

The electrical opening and closing means that the electrical opening and closing is electrically opened to allow electricity to pass therethrough and the electrical closing to prevent the electricity from flowing. The electrical opening may be defined as closing of the driving control element, and the electrical closing may be defined as opening of the driving control element.

On the other hand, the power source (P) and the signal applied to the drive control element through the input terminal and output through the output terminal of the drive control element can be modulated. However, for convenience of explanation, the power source P and the signal applied to the input terminal of the switch and the power source P and the signal outputted from the output terminal of the switch are described without discrimination.

The switch may electrically short-circuit the first electrical component connected to the input and the second electrical component connected to the output. The short circuit may be caused by an open / close signal applied to the gate.

Alternatively, the drive control element 1300 may be implemented as a switch as well as a drive control element 1300 that controls the polarity of the power or signal output from the drive control element 1300. [ A duplicate description of the function of the switch will be omitted.

The gate And may be connected to the output terminal of the first driving control element 1301 through a control line 1260. [

1.4 Placement Relationship

12 is a view showing the inside of the 2D thermal sensation providing apparatus 1 according to the embodiment of the present application.

Hereinafter, the driving module 1200 and the thermoelectric module 1100 of the 2D thermal sensation providing device 1 will be described in detail with reference to FIG.

The thermoelectric module 1100 and the driving module 1200 according to an embodiment of the present application may be disposed inside the 2D thermal sensation providing device 1 so as to face each other.

The thermoelectric module 1100 is disposed on one surface of the first substrate 110 and the driving module 1200 may be disposed on one surface of the second substrate 120 facing the first surface of the first substrate 110 have.

In this case, corresponding to each thermoelectric region of the thermoelectric module 1100 disposed on the first substrate 110, driving pixels of the driving module 1200 disposed on the second substrate 120 may be positioned have.

A plurality of data lines 1250, a plurality of gate lines 1270, and a plurality of output lines may be arranged such that each of the driving pixels is positioned corresponding to each thermoelectric region. For example, the first gate line 1271, the first data line 1251, and the first output line are arranged such that the first driving pixel 1201 is located corresponding to the first thermoelectric element group 1111 .

A driving control element 1300 may be disposed on the second substrate 120 corresponding to each thermoelectric element group 1110 disposed on the first substrate 110. For example, the driving control element 1300 may be disposed so as to face the first thermoelectric element group 1111 disposed on the first substrate 110.

A base 130 is disposed between the first substrate 110 and the second substrate 120. The first substrate 110 and the base 130, the second substrate 120, and the base 130 May be spaced apart from each other by a predetermined distance. In other words, a predetermined gap may be formed between the first substrate 110 and the base 130, and between the second substrate 120 and the base 130.

The spacing may be determined by a thermoelectric element group 1110 disposed on the first substrate 110 and a driving module 1200 disposed on the second substrate 120.

For example, the distance between the first substrate 110 and the base 130 corresponds to the height of the thermoelectric element group 1110 disposed on the first substrate 110 in the direction of the base 130 . Accordingly, the thermoelectric element group 1110 contacts the base 130, and the heat of the thermoelectric element group 1110 can be smoothly reduced through the base 130. Alternatively, the distance between the first substrate 110 and the base 130 may be slightly larger than the height of the thermoelectric element group 1110 disposed on the first substrate 110. Accordingly, the thermoelectric element group 1110 may be spaced apart from the base 130.

Also, for example, the interval may be determined such that the driving module 1200 and the base 130 are spaced apart from each other by a predetermined distance. As the driving module 1200 is disposed apart from the base 130, heat conducted from the thermoelectric element group 1110 to the driving module 1200 through the base 130 is transmitted to the driving module 1200 1200 from being transported. Accordingly, deterioration of the driving module 1200 can be prevented.

The opposing driving pixels and thermoelectric regions may be electrically connected by a driving wire 150. The thermoelectric element group 1110 disposed in each of the plurality of thermoelectric regions may be electrically connected to the driving control element 1300 of the driving pixel arranged to face by the driving wire 150. [

For this purpose, a via hole 137 may be formed at the position of the base 130 corresponding to the thermoelectric region and the driving pixel.

The via hole 137 may be formed at each of the plurality of thermoelectric regions, or at a position corresponding to each of the plurality of driving pixels arranged to face each other. For example, a plurality of first via holes 137 may be formed at positions of the base 130 corresponding to the first thermoelectric conversion area 111 and the first driving pixel 1201.

The via hole 137 may be formed corresponding to each of the thermoelectric element groups 1110 or each of the drive control elements 1300 disposed to face each other. For example, a plurality of first via holes 137 are formed in the base 130 corresponding to the first thermoelectric element group 1111, the first driving control element 1301 and the second driving control element 1303 . The thermoelectric element group 1110 may be exposed in the direction of the second substrate 120 through the via hole 137. Specifically, the first conductor member 1115 of the thermoelectric element group 1110 may be exposed through the via hole 137.

The driving wire 150 extends through the via hole 137, thereby electrically connecting the driving pixel and the thermoelectric region facing each other. For example, the first driving wire 150 extends from the first driving pixel 1201 through the first via hole 137 to the first thermoelectric conversion area 111, and extends to the thermoelectric conversion element group 1110 Can be contacted.

The driving wire 150 extends through the via hole 137 to electrically connect the driving control element 1300 and the thermoelectric element group 1110 to each other. The driving wire 150 is connected to the output terminal of the driving control element 1303 or 1305 and may be connected to at least one of the plurality of first conductive members 1115 of the thermoelectric element group 1110. [

The other first conductor member 1115 other than the first conductor member 1115 of the thermoelectric element group 1110 electrically connected to the drive control element 1303 or 1305 by the drive wire 150 Another driving wire 150 may contact and extend in the direction of the driving pixel. Another driving wire extending in the direction of the driving pixel may pass through the via hole 137 formed in the base. The driving wire passing through the via hole 137 is connected again to the power generating unit 1210 so that the power applied to the thermoelectric element group 1110 is returned to the power generating unit 1210 again.

As a result, the driving wire 150 electrically connects the driving control element 1300 disposed on the second substrate 120 to the thermoelectric element group 1110 disposed on the first substrate 110, And the thermoelectric module 1100 can be driven by the driving power source (I) output from the driving module 1200.

The driving wire 150 extends through the via hole 137 so that the driving module 1200 and the thermoelectric module 1100 have the shortest electrical distance.

The driving wires 150 connecting the thermoelectric element groups 1110 disposed in the respective thermoelectric regions and the driving control elements 1300 disposed in the respective driving pixels facing each other may extend to the same or similar lengths have. The via holes 137 may be formed so that the distance between the corresponding thermoelement groups 1110 and the driving control elements 1300 are the same or opposite to each other through the via holes 137. [

Accordingly, it is possible to prevent the malfunction of the 2D thermal sensation providing device 1 from being prevented. When the lengths of the driving wires 150 connecting the thermoelectric regions and the driving pixels corresponding to the thermoelectric regions are different for each region, it may be difficult to control the driving power source I applied for each thermoelectric region. Specifically, even if the driving power source I outputted from the driving pixel is the same for each driving pixel, the distance between the driving pixel and the thermoelectric region corresponding to the driving pixel is different and the driving power source I is transmitted, Lt; RTI ID = 0.0 > 1110 < / RTI > In order to compensate the driving power I applied to the different magnitudes, a predetermined compensation circuit is required. On the other hand, when the distance between the thermoelectric conversion area and the driving pixel is set to be the same, the above-mentioned non-fixing is solved and malfunction of the thermoelectric conversion element group 1110 driven for each thermoelectric conversion area can be prevented.

Hereinafter, the heat providing operation of the 2D thermal sensation providing apparatus 1 will be described.

The thermoelectric data generation and transfer may be a step of generating and transmitting data for thermally representing a thermal reproduction object.

Generation of the driving power source I generates driving power I to be provided to each thermoelectric element group 1110 so that the thermoelectric element groups 1110 arranged for each thermoelectric region perform a thermoelectric action, ). ≪ / RTI >

The control of the magnitude and the polarity of the heat sensation may be a step of controlling the generation of the driving power I to control the heat sensation provided to the user.

Hereinafter, the respective steps of the above-described operation of generating the driving power supply I will be described in detail.

2.1 Acquire and transfer thermoelectric data

13 is a view showing a thermally conductive surface including a plurality of regions and thermoelectric data related thereto according to an embodiment of the present application.

In accordance with the thermoelectric data generation operation, the 2D thermal sensation providing device 1 may acquire thermoelectric data for thermally expressing a thermal reproduction object. The thermoelectric data may be data relating to the hot feeling providing surface or the hot feeling providing stream provided to the user from the 2D hot feeling providing device 1 for the user's thermal experience. Hereinafter, the thermoelectric data is data concerning the hot feeling providing surface .

Referring to FIG. 13, the thermoelectric data may include coordinate information to which a heat sensation is imparted by the thermoelectric data, size information of heat sensation, and type information of heat sensation.

The annotation coordinate information may be information on the coordinate value of the driving pixel corresponding to the area of the hot feeling providing surface. For example, the first area of the hot-feeling providing surface may correspond to the first driving pixel and the corresponding coordinate value (1,1) may be set, and the second area of the hot- Pixels, and coordinate values (2,2) corresponding thereto can be set. The coordinate information may include the coordinate values described above.

The size information may be information related to the magnitude of the thermal sensation in the area of the hot feeling providing surface.

The type information may be information related to the type of heat sensation in the area of the heat sensation providing surface.

Hereinafter, each piece of information included in the thermoelectric data will be described in detail.

The coordinate information of the thermoelectric data may cause a driving pixel for outputting the driving power I to be selected.

By selecting the driving pixel, a power source (P) or a signal applied to the output lines defining the driving range can be controlled. For example, when the first driving pixel 1201 is selected by the coordinate information of the thermoelectric data, the first data line 1251, the first gate line 1271, And the signal applied to the first power line 1291 or the power source P can be controlled.

The magnitude information and the type information of the thermoelectric data may be selected in size and polarity of the driving power source (I) output from the driving pixel. In other words, the size information is information for controlling the size of the driving power source I to control the degree of the thermal sensation provided to the user, and the polarity information may include driving power I And the polarity of the polarity of the signal.

For this purpose, the magnitude information and the type information may control the magnitude and polarity of the power (P) or signal applied to the output lines. In other words, the magnitude information and the type information can be generated by the power generator 1210 and the signal generator 1230 with different magnitudes and polarities of power (P) or signals.

The generated thermoelectric data is transmitted to a power generator 1210, a signal generator 1230, a controller, or the like, and the thermoelectric data can be used in each configuration that receives the thermoelectric data. For example, when the thermoelectric data is transmitted to the signal generation unit 1230, the signal generation unit 1230 calculates the magnitude and polarity of the signal to be applied to the selected driving pixel based on the coordinate information, And generate the corresponding signal. When the thermoelectric data is transmitted to the power generation unit 1210, the power generation unit 1210 can use the thermoelectric data as in the signal generation unit 1230.

On the other hand, the thermoelectric data can be generated based on data acquired from an external device through the communication unit or data input from the user of the 2D thermal sensation providing apparatus 1. [ For example, the data may be image data for a thermal reproduction object. The image data may be converted into thermoelectric data and used in accordance with the thermoelectric data generation and transfer operation of the 2D thermal sensation providing device 1. [ For example, the color data of the image data may be converted into thermoelectric data.

In order to provide the user with a sense of heat in each region, the 2D thermal sensation providing apparatus 1 may include a driving power source (I) for each driving pixel corresponding to the thermoelectric region, so that the thermoelectric element group 1110 can perform a thermoelectric operation for each thermoelectric region, Can be generated.

As described above, the 2D warmth providing apparatus 1 can provide a user with a warm feeling providing stream. The hot feeling providing stream may be composed of a plurality of heat providing surfaces. Therefore, the 2D thermal sensation providing apparatus 1 can provide the user with a heat sensation providing surface in order to provide a sensation providing stream to the user.

The driving power source I may be generated by a power source and a signal applied to each driving pixel during a predetermined frame for constructing a heat providing surface. The frame may be defined as a time until a data signal is applied from a data line for every driving pixel. The time until the data signal is applied may be determined by the number of rows or columns of the thermoelectric element group or the number of rows or columns of the driving pixels. The time until receiving can be long. The time when the data signal is applied may be defined as a line time (lt), so that one frame may be composed of a plurality of line times (lt). There may be at least one frame constituting the hot-feeling providing surface in which the shuffling is performed, and thus the control method of the power source and the signal applied to each driving pixel may be different, which will be described in detail later.

Hereinafter, a description will be made of the generated driving power source I in the case where power and signal are applied to the driving pixel for each frame.

The driving power I may be generated by a power source and a signal applied to each driving pixel for each line time (lt) of the frame. A driving pixel is determined according to a gate signal GSG and a data signal DSG applied to one line time lT and a driving power source I is determined based on a power source P applied to the driving pixel from the driving pixel, Can be output. Specifically, when the gate signal GSG and the data signal DSG applied to one line time (lt) are applied to the first driving control element 1301 of one driving pixel, the driving pixel can be selected. The first drive control element 1301 of the selected drive pixel transmits a data signal to the second drive control element 1303 connected to the first drive control element 1301 to electrically drive the second drive control element 1303 And the driving power source I is outputted through the second driving control element 1303. [

As a result, the gate signal GSG and the data signal DSG are applied to the driving pixel until the last line time (lt), and the driving power I is outputted for each driving pixel during one frame. In addition, the driving pixels to which the driving power I is output may be different for each line time (lt). A first driving power I may be output from the first driving pixel 1201 and a second driving power I may be output from the second driving pixel 1203. [

The first driving control element 1301 is electrically driven according to the first gate signal GSG1 applied to the first line time lt1 outputted to the first driving control element 1301 of the first driving pixel 1201 Lt; / RTI > At this time, the first data signal DSG1 applied to the first driving control element 1301 is applied to the gate of the second driving control element 1303 and is simultaneously applied to the input of the second driving control element 1303 The first power source P1 may be output. The first driving power source I1 is determined based on the gate of the second driving control element 1303 and the power source P of the input stage and the data signal DSG, May be applied to the second thermoelectric element group 1113 electrically connected to the second driving control element 1303 of the first driving pixel 1201. [

And the second driving power source I may be output from the second driving pixel 1203. The first drive control element 1301 is electrically driven according to the second gate signal GSG2 applied to the second line time lt2 applied to the first drive control element 1301 of the second drive pixel 1203 Lt; / RTI > At this time, the second data signal DSG2 applied to the first driving control element 1301 is applied to the gate of the second driving control element 1303 and is simultaneously applied to the input of the second driving control element 1303 The second power source P2 may be applied. The first driving power source I1 is determined based on the gate of the second driving control element 1303 and the power source P of the input stage and the data signal DSG, May be output to the second thermoelectric element group 1113 electrically connected to the second driving control element 1303 of the second driving pixel 1203.

Similarly, the drive power source I may be generated and output in the remaining drive pixels during one frame.

The control of the magnitude and polarity of the heat sensation will be described below.

On the other hand, there may be an initial temperature setting operation of the 2D thermal sensation providing apparatus 1 before the control of the magnitude and polarity of the thermal sensation. This may be done by outputting the driving power I of the same size to all the driving pixels to make the temperature of the area of the 2D heating sensation providing device 1 corresponding to the upper driving pixel constant. In this case, the temperature may be set on the basis of the normal body temperature of the user, which prevents the user from feeling warm or cool feeling, and the information on the normal body temperature may be preset.

2.3 Control of Size and Type of Heat Sensation

It is possible to control the size of the heat sensation and the kind of the heat sensation according to the area of the heat sensation providing surface according to the embodiment of the present application. Accordingly, the size and the kind of heat sensation provided to the user for each region can be adjusted to be different from each other.

FIG. 14 is a view showing a heat providing surface having a different size of heat sensation according to an embodiment of the present application.

FIG. 15 is a view showing a heat providing surface having different kinds of heat sensations according to an embodiment of the present application. FIG.

Referring to FIGS. 14 and 15, the size and the kind of heat sensation provided for each region of the heat sensation providing surface may be different from each other. The region may include a first region and a second region. For example, the size of the first area may be greater than the size of the second area, and the type of the first area may be opposite to the type of the first area. In other words, the information about the size of the thermal sensation included in the corresponding thermoelectric data may differ from the information about the sensation of thermal sensation for each region of the thermal sensation providing surface.

In order to express different heat sensations for each of the areas, it is possible to control the time and frequency of application of the driving power to the thermoelectric element group, or to control the power and signal applied to each frame to implement the heat sensation providing surface.

The control of the driving power applied to the thermoelectric element group can be determined according to the overlapping time of the signal applied to the driving pixel and the power source.

As a method of controlling the power source and the signal applied to each frame, a plurality of frames for realizing a hot feeling providing surface are provided, and the output of the driving power source I during the progress of a plurality of frames (Ii) a method of controlling the output of the driving power supply I during one frame to implement the heating surface.

Hereinafter, each of the thermal sensation control methods will be described in detail. The control method described below can be applied to the drive control element 3010 and the drive control element 3020 described above. That is, the meaning of controlling the signal applied to the one driving pixel is specifically the gate signal applied to the first driving control element 3001 of the driving control element 3010 or the driving control element 3020 disposed in one driving pixel, And to control the data signal. The meaning of controlling the power source to which one drive pixel is applied means that the power applied to the second drive control element 3003 of the drive control element drive control element 3010 or the drive control element 3020 disposed in one drive pixel is controlled Can be interpreted as doing. That is, the following control method can be applied to the drive control element 3010 and the drive control element 3020, without being limited to the drive control element shown in the following description.

2.3.1 Overlap time control

The control of the size of the thermal sensation by the area according to the embodiment of the present application can be controlled according to the application time or the number of times of application of the driving power to the thermoelectric element group 1110 corresponding to the area. For example, the magnitude of the thermal sensation provided by the thermoelectric element group 1110 may be increased in proportion to the time or the number of times of the driving power applied to the thermoelectric element group 1110. In other words, by controlling the time or the number of times of the driving power source I output for each driving pixel, the heat sensation provided to the user from the thermoelectric element group 1110 corresponding to the driving pixel can be controlled.

16 is a diagram showing an example in which the time or frequency of the driving power outputted from one driving pixel according to the embodiment of the present application is controlled.

17 is a diagram illustrating an example in which a data signal is controlled to control an output of the driving power source according to an embodiment of the present application.

Referring to FIG. 16, the time or the number of times of the driving power I output to the thermoelectric element group 1110 in one driving pixel may be determined by a signal and a power source applied to the driving pixel. Specifically, the output time or the number of times of the driving power may be determined according to the time or the number of times of overlapping of the data signal DSG, the gate signal GSG, and the power source P applied to the driving pixel. For example, when the overlap time is increased, the output time of the driving power supply I may be increased, and the number of times of output of the driving power supply I may be increased when the number of overlaps is increased. On the contrary, the output time or the number of times of the driving power source I may be reduced as the overlap time and the number of times decrease.

Hereinafter, the output time or the number of times of the driving power I outputted according to the control of the data signal DSG will be described. However, the gate signal GSG and the power source can be controlled in the same manner as the control method of the data signal DSG described later without being limited to the following description.

Referring to FIG. 17, the output time or frequency of the driving power may be controlled according to the control of the data signal DSG. That is, the output time or the number of times of the driving power I outputted from one driving pixel can be controlled according to the time or number of times the data signal DSG is applied to one driving pixel. In other words, the output time or frequency of the driving power I outputted from the one driving pixel to the thermoelectric element group can be determined according to the application time or the number of times of the data signal DSG applied to one driving pixel. That is, according to the control of the data signal DSG, the control of the thermal sensation provided to the user by the thermoelectric element group 1110 can be realized.

Specifically, as the data signal DSG applied to one driving pixel is controlled, the time and frequency of the driving power source I to which the overlapping time is controlled can be controlled. For example, as the application time or the number of times the data signal DSG is increased, the time or the number of times of overlapping the driving power source I may be increased and the outputting time or frequency of the driving power source I may be increased.

In addition, the output driving power I may have a predetermined time level. The output time or frequency of the driving power may be determined according to the time level. For example, the time level may have a first time level to a fifth time level (TI1 to TI5), and the driving power may be output from the first time level to the fifth time level (TI1 to TI5) Time can be increased.

And the data signal may be applied corresponding to the time level. That is, the time or frequency of the data signal applied to one driving pixel per time level is determined, and the data signal may be applied to the one driving pixel according to the time level. For example, the time or number of times that the data signal is applied to the one driving pixel in the first time level to the fifth time level sequence (TI1 to TI5) is increased so that the fifth time level The time or the number of times the driving power I is output in the order TI1 to TI5 may be increased.

Meanwhile, the gate signal GSG or power source other than the data signal DSG may be applied for a predetermined time period. Specifically, the data signal DSG applied to one driving pixel and the power source may be applied at least for a time longer than a time when the data signal can be maximally applied.

Alternatively, at least one of the gate signal GSG and the power source may be associated with a time interval during which the data signal DSG is applied. For example, when the data signal DSG is applied to the one driving pixel for the first time according to the first time level TI1, the gate signal GSG or the power source P ) May be applied.

The magnitude of the data signal DSG, the gate signal GSG, and the power source P may be appropriately adjusted, but the magnitude of the data signal DSG, the gate signal GSG, and the power source P may be kept constant and adjusted only as described above. This is because the magnitude of the thermal sensation provided to the user from the thermoelectric element group 1110 can be determined according to the time or the number of the driving power I applied to the thermoelectric element group 1110.

In the above, an example has been described in which the time or frequency of the driving power source I applied to the thermoelectric element group 1110 is controlled for the control of the thermal sensation.

In Ahi, a method of controlling the above-described warmth by placing a frame will be described.

2.3.2 Multiple Frame Control

The control of the magnitude and the kind of the thermal sensation according to the embodiment of the present application can be performed by controlling the output of the driving power source I for each driving pixel during a plurality of frames for realizing the thermal sensation providing surface. That is, in this case, the heat-providing surface may be implemented as a plurality of frames. The driving power source I is outputted for each driving pixel during a plurality of frames constituting the heat-providing surface, whereby one heat-providing surface can be completed. Each of the plurality of frames may be defined as a sub-frame (frame n, n is an integer).

18 is a conceptual diagram showing that the timing of a power source P and a signal applied to each driving pixel are controlled according to an embodiment of the present application.

Referring to FIG. 18, the characteristic of the thermal sensation can be controlled according to the driving power I outputted during the plurality of sub-frames. The characteristic of the thermal sensation may include a level of thermal sensation and a polarity of thermal sensation. The level of the heat sensation may mean the degree of heat sensation provided to the user. The number of levels of the heat sensation can be appropriately preset according to the purpose of implementation. For example, the number of levels can have two levels. At the same time, the level of the hot feeling can be applied to the hot feeling of different polarity. For example, if the warmth has a plurality of levels, the cool feeling may also have a plurality of levels corresponding thereto.

During the one sub-frame, a power source (P) and a signal may be applied to each driving pixel.

The subframe may include a plurality of line times (lt). The gate signal GSG and the data signal DSG may be applied for each of the line times (lt).

A power source (P) may be applied during the subframe. The polarities of the power sources P applied to the subframes may be different from each other. As shown in the figure, the power source P having different polarities may be applied to each successive subframe. However, the polarity of the power source P applied to each subframe (frame n, n is an integer) . For example, a power source P having the same polarity is applied during the first sub-frame 1 and the second sub-frame 2, and a third sub-frame 3 and a fourth sub- The first polarity and the second polarity may be different from each other.

The heat sensation provided to the user for each region can be adjusted based on the driving power I output for each driving pixel during a plurality of sub-frames. The driving power source (I) output for each driving pixel can be controlled by a power source (P) and a signal applied to the driving pixel during a plurality of subframes. That is, the magnitude and polarity of the driving power I output for each driving pixel can be adjusted according to a power source P and a signal applied to the driving pixel during a plurality of sub-frames. Specifically, the magnitude and polarity of the driving power source I output for each driving pixel is determined by the number of times the gate signal GSG or the data signal DSG applied to the driving pixel is applied during one frame, Can be determined according to the polarity of the voltage (P).

As a result, the heat sensation provided to the user for each of the regions is determined by the number of times the gate signal GSG or the data signal DSG applied to the driving pixel is applied during the frame and the polarity of the applied power P Can be determined accordingly.

Hereinafter, each of the level of the thermal sensation and the polarity of the thermal sensation controlled for each driving pixel will be described.

2.3.2.1 Heat level control

The magnitude of the thermal sensation provided to the user according to an embodiment of the present application may be determined according to the number of times of output of the driving power source I. [ In other words, the magnitude of the thermal sensation provided to the user by the 2D thermal sensation providing device 1 can be determined according to the number of outputs of the driving power source I. Specifically, the level of the heat sensation provided to the user in one region may be determined based on the number of times the driving power source I is outputted in the driving pixel corresponding to the region.

The level of the heat sensation may be preset according to the number of times of output of the driving power source I. [ For example, when the level of the thermal sensation includes a first level and a second level, the first level corresponds to a first output number of the driving power source I, And may be previously set to correspond to the second output number. Accordingly, the level of the thermal sensation provided for each region can be controlled by controlling the number of outputs of the driving power source (I) of the driving pixel corresponding to the region.

19 is a diagram showing the number of times the driving power source I is outputted for each driving pixel according to the embodiment of the present application.

Referring to FIG. 19, the number of driving power sources I output for each driving pixel may be controlled so that a warm feeling having a different size is provided for each region.

Hereinafter, an embodiment for adjusting the number of outputs of the driving power source I for each driving pixel will be described.

20 is a diagram illustrating a driving pixel selected according to a signal applied to each subframe according to an embodiment of the present application.

Referring to FIG. 20, the number of times the driving power source I is output from the driving pixel may be determined by the number of subframes in which the driving pixel is selected. The number of subframes in which the driving pixel is selected may be determined by a power source P and a signal applied during the progression of a plurality of subframes.

In other words, the signal applied during the plurality of sub-frames and the power source P can determine the driving pixel from which the driving power source I is output. For example, when the first gate signal GSG1, the first data signal DSG1, and the first power source P1 are applied to the first line time lt1 of the first subframe frame1, The driving pixel 1201 can be determined.

Accordingly, the number of times the driving power (I) is outputted from the driving pixel can be determined. The number of subframes in which the driving pixel is selected can be determined by applying a power source P to a signal for determining the driving pixel during a plurality of subframes implementing the heat providing surface. Since the driving power source (I) is outputted from the driving pixel during the sub-frame, the number of times of output of the driving power source (I) can be determined based on the determined number of sub-frames. For example, during a plurality of sub-frames for implementing a heat-providing surface in the first driving pixel 1201, a gate signal GSG and a data signal (data signal) are supplied through a first gate line 1271 and a first data line 1251, And the number of outputs of the driving power source I of the first driving pixel 1201 is determined according to the number of subframes to which the first power source P1 is applied through the first power line 1291 .

As a result, the level of the thermal sensation per region can be determined based on the gate signal GSG, the data signal DSG, and the power source P applied for each driving pixel during a plurality of sub-frames.

On the other hand, in order to provide the user with a certain level of warmth as shown, the subframe to which the signal is applied can be selected. In order to provide the user with the level of one kind of heat sensation, the number of times of the driving power I output by the power source P having the polarity corresponding to the type of heat sensation should be controlled. To this end, during the sub-frame in which the power source P having the corresponding polarity is applied, the gate signal GSG and the data signal DSG may be applied to the driving pixel for providing the thermal sensation.

The polarity of the power source P applied during the subframe may be preset, but may be changed appropriately. For example, when the level of one kind of heat sensation required for the plurality of subframes is high, the number of subframes to which the power source P of the polarity corresponding to the level is applied can be increased.

Hereinafter, the polarity control of the thermal sensation by each region will be described.

2.3.2.2 Control of heat type

The kind of heat sensation provided to the user according to the embodiment of the present application can be determined based on the polarity of the driving power source I outputted.

The control of the polarity of the output driving power I may be performed by selecting a subframe to which the power P of the polarity is applied. The polarity of the power source P applied to each subframe during the plurality of subframes may be different. In other words, a power source P of the first polarity may be applied to some of the plurality of subframes, and a power source P of the second polarity may be applied to some of the other frames. Therefore, when selecting the subframe to which the power supply P having the polarity is applied, the polarity of the driving power supply I is controlled so that the polarity of the heat sensation provided to the user can be controlled.

On the other hand, the polarity of the power source P applied to each subframe may be variously set. The application of the power source P having different polarities to the successive sub-frames in sequence is an example, and may be applied in various other ways.

FIG. 21 is a diagram showing the polarity of the driving power source I outputted for each driving pixel according to the embodiment of the present application.

Referring to FIG. 21, the polarity of the driving power I output for each driving pixel can be controlled so that different types of heat are provided to the user for each region.

22 is a diagram showing signals applied to each subframe in order to control the polarity of an output driving power source I according to an embodiment of the present invention.

Referring to FIG. 22, a sub-frame to which a power source P having a polarity corresponding to a type of a thermal sensation to be provided is applied and a signal is applied to the sub-frame to drive the driving power source I, . For example, in order to provide a kind of thermal sensation, a signal can be applied by selecting a subframe to which a power source P having a polarity corresponding to one type is applied. The signal may be applied to select an area where the driving power I is outputted.

The polarity of the drive power source I may be changed by i) the power source generation unit 1210 itself or ii) the drive control element 1300 implemented on the output line from the power source generation unit 1210 ≪ / RTI >

On the other hand, the above-described control of the heat sensitivity level and the control of the heat sensibility can be implemented in combination. For example, in order to provide a kind of warmth having a predetermined level through one region, a subframe to which a power source (P) of a polarity corresponding to the type is applied is selected, It is possible to apply a signal to the driving pixel corresponding to the region by the number of output times of the corresponding predetermined driving power source I. [

2.3.3 Day frame control

The control of the magnitude and the kind of the heat sensation according to the embodiment of the present application can be performed by controlling the magnitude and polarity of the driving power I outputted during one frame constituting the heat sensation providing surface. Specifically, by applying the driving power source I having a magnitude corresponding to the magnitude of the thermal sensation to the thermoelectric element group 1110, the corresponding thermoelectric action can be performed to provide the user with different senses of heat. In addition, by applying the driving power source I having the polarity corresponding to the type of the thermal sensation to the thermoelectric element group 1110, the corresponding thermoelectric action can be performed to provide different kinds of heat sensation to the user.

23 is a diagram showing a drive control element 1300 of one drive pixel according to an embodiment of the present application.

24 is a diagram showing a drive control element 1300 according to an embodiment of the present application.

Referring to FIG. 23, the magnitude and polarity of the driving power source I output from the driving pixel according to an embodiment of the present application can be determined by the power source P and the signal applied to the driving pixel. Specifically, the driving power source I for each driving pixel can be generated in correspondence with the difference between the power source P and the data signal DSG applied to the second driving control element 1303.

Hereinafter, the magnitude and polarity of the driving power I output for each driving pixel during one frame will be described.

The driving pixel for outputting the driving power I during the above-described frame may be determined by the gate signal GSG and the data signal DSG. The first driving control element 1301 of the driving pixel receives the gate signal GSG and the data signal DSG during the line time ll so that the driving pixel outputs the driving power I .

The second driving control element 1303 of the driving pixel can define the magnitude and polarity of the driving power I output from the driving pixel. The second drive control element 1303 is electrically opened in accordance with the data signal DSG applied from the first drive control element 1301 during the line time lt of the second drive control element 1303, It is possible to output the driving power source I based on the difference between the power source P applied to the input terminal and the gate and the signal. More specifically, the second driving control element 1303 can output the driving power I in accordance with the difference between the applied power P and the data signal DSG.

That is, when the data power source P is applied to the driving pixel at the line time (lt) at which the gate signal GSG is output from the gate line 1270 defining the driving pixel, The driving power source I corresponding to the difference between the power source P applied to the power source P and the data power source P can be output.

The magnitude and polarity of the driving power I outputted from the driving pixel during the above-described frame can be controlled.

Referring to FIG. 24, the size and polarity of the driving power source I may be determined based on the size of the power source P applied to the driving pixel, or the size of the signal.

Referring to FIG. 24 (a), the magnitude and polarity of the driving power source I outputted from the driving pixel can be performed by controlling the power source P. FIG. Specifically, when the data signal DSG applied to one driving pixel is constant, the magnitude and polarity of the driving power I outputted from the driving pixel are controlled by controlling the magnitude of the power source P applied to the driving pixel .

Referring to Fig. 24 (b), the magnitude and polarity of the driving power source I output from the driving pixel can be performed by controlling the data signal DSG. More specifically, when the power source P applied to one driving pixel is constant, the magnitude and polarity of the driving power source I outputted from the driving pixel are controlled by controlling the magnitude of the data signal DSG applied to the driving pixel .

On the other hand, the magnitude and polarity of the driving power source I may be predetermined for each magnitude and type of heat sensation. The magnitude of the thermal sensation may exist at a plurality of levels, and the output level of the driving power source I corresponding to the level may be preset. When the magnitude of the thermal sensation is the first level, the magnitude of the driving power source I to be output in order to achieve this is preset to the first output level, and when the magnitude of the thermal sensation is the second level, The magnitude of the driving power source I to be supplied may be preset to the second output level. In this case, the first output level and the second output level may be different from each other.

The output polarity of the driving power supply I corresponding to the polarity of the heat sensation may be preset. In this case, the concept of the output level of the driving power source I according to the level of the above-described heat sensation can be applied.

Hereinafter, the control of the magnitude and polarity of the driving power I outputted in one frame for controlling the heat sensation provided to the user will be described.

2.3.3.1 Driving power size control

25 is a diagram showing an example in which the magnitude of the driving power source I is controlled for each driving pixel according to the embodiment of the present application.

26 is a view showing an example of controlling a power source P or a signal applied to each driving pixel according to an embodiment of the present application.

27 is a diagram showing an example of controlling a power source P or a signal applied to each driving pixel according to an embodiment of the present application.

There may be a plurality of regions having different heat sensations provided to the user.

Referring to FIG. 25, a driving power source I having a magnitude corresponding to the magnitude of the thermal sensation may be output for each of the regions to provide heat senses of different sizes for the respective regions. Specifically, a driving pixel corresponding to the region is selected during one frame, and the driving power source I corresponding to the magnitude of the heat sensation can be controlled to be output from the driving pixel.

The size of the power source P or signal applied for one frame may be controlled for outputting the driving power source I having different sizes for each driving pixel.

Referring to FIG. 26, the size of the driving power I output for each driving pixel can be controlled according to the size of the power source P. FIG.

When the magnitude of the data signal DSG output for each driving pixel is the same, the magnitude of the power source P outputted to the driving pixel and the magnitude of the driving power source I outputted from the driving pixel may be proportional to each other have. In other words, when the size of the power source P is increased, the size of the driving power source I can be increased. Conversely, when the size of the power source P is reduced, the size of the driving power source I output can be reduced.

In order to make the size of the driving power source I outputted from the driving pixel different during the frame, the data signal DSG is applied to the driving pixel during the corresponding line time (lt) of the driving pixel, It is possible to control the power source P to be controlled. The size of the power source P may be controlled according to the magnitude of the heat sensation to be provided to the user. That is, when the size of the heat sensation is large, the size of the power source P applied to the driving pixel can be increased.

Meanwhile, although the magnitude of the power source P applied during one frame is shown to be constant, it is preferable that the magnitude of the power source P is maintained only during the corresponding line time lt . In other words, a power source P having a magnitude for controlling the size of the driving power source I is supplied only during the line time (lt) at which the driving power source I is output from the driving pixel, , A power source P having a magnitude for controlling the magnitude of the driving power I output from the other driving pixel may be supplied.

The control of the size of the power source P may be performed by the power generator 1210 or may be performed by a drive control element 1300 connected to the power line 1290 output from the power generator 1210 . The power control unit 1215 may control the size of the power source P when the power source generation unit 1210 performs the control.

The driving control element 1300 connected to the power line 1290 may be an amplifier element. The amplifier elements may be coupled to each of the power lines 1290. In addition, a controller for controlling the amplifier element may be further implemented in the driving unit.

Referring to FIG. 27, the magnitude of the driving power source I may be controlled according to the control of the magnitude of the data signal DSG.

If the magnitude of the power source P output for each driving pixel is the same, the magnitude of the data signal DSG output to the driving pixel and the magnitude of the driving power I output from the driving pixel may be inversely proportional to each other have. In other words, when the size of the data signal DSG is reduced, the size of the driving power source I may be increased. Conversely, if the magnitude of the data signal DSG is increased, the magnitude of the driving power supply I output can be reduced.

In order to vary the magnitude of the driving power source I outputted from the driving pixel during the above-mentioned frame, it is preferable that a predetermined power source P is applied to the driving pixel during one frame, It is possible to control the data signal DSG applied to the driving pixel during the time (lt). The size of the driving power source I outputted from the driving pixel can be controlled by controlling the magnitude of the data signal DSG applied to the driving pixel during the line time (lt).

The magnitude of the applied data signal DSG can be controlled according to the magnitude of the heat sensation to be provided to the user. That is, when the magnitude of the thermal sensation is large, the magnitude of the data signal DSG applied to the driving pixel can be reduced.

36 is a schematic diagram illustrating a thermoelectric drive assembly 2000 in accordance with one embodiment of the present application.

37 is a diagram showing a thermoelectric element group electrically connected by a connection line 2500 according to an embodiment of the present application.

36, a thermoelectric module 2000 according to an embodiment of the present invention includes a signal generator including a gate signal source 2231 and a data signal source 2235, a power generator 2210, A group 2110, and a switch 2300 may be provided.

One gate line 2250 of the plurality of gate lines extending from the gate signal source 2231 may be connected to each switch 2300 of the driving pixels arranged in one direction. In other words, each switch 2300 of the driving pixels arranged in one direction may be connected to the same gate line 2250.

A data line 2270 of the plurality of data lines 2270 extending from the data signal source 2235 may also be connected to each switch 2300 of the driving pixels in the same manner as the gate line 2250. Therefore, redundant description thereof will be omitted.

One power line 2290 of the plurality of power lines extending from the power generating unit 2210 is connected to a switch 2300 and a thermoelectric element group 2110 disposed in a driving pixel among the driving pixels arranged in one direction . In other words, the switch 2300 and the thermoelectric element group 2110 of one driving pixel among the driving pixels arranged in one direction can be all connected to the one power line 2290. To this end, one power line 2290 extending from the power generating unit 2210 may be branched and connected to the thermoelectric element group 2110 and the switch 2300 at the same time. At this time, the switch 2300 contacting the power line 2290 is defined as a first switch 2301, the thermoelectric element group 2110 is defined as a first thermoelectric element group 2111, the first switch 2301 ) And the first thermoelectric element group 2111 are arranged may be defined as a first driving pixel 2201.

Specifically, the connection line 2500 can electrically connect the switch 2300 disposed in one driving pixel and the thermoelectric element group 2110 and the switch 2300 and the thermoelectric element group 2110 disposed in the other driving pixel have. To this end, the connection line 2500 is branched and contacts the switch 2300 and the thermoelectric element group 2110 disposed in one driving pixel, and is connected to the switch 2300 and the thermoelectric element group 2110 disposed in the other driving pixel And can be brought into electrical contact with each other.

On the other hand, the one direction is a specific direction, and the specific direction is not limited to any direction but may be a lateral direction, a longitudinal direction, or a diagonal direction.

Hereinafter, the electrical connection relationship between the switch 2300 and the thermoelectric element group 2110 arranged for each driving pixel will be described.

The at least two switches 2300 and the thermoelectric element group 2110 disposed for each driving pixel may have an electrically parallel relationship. Accordingly, the switch 2300 and the thermoelectric element group 2110 disposed in the one driving pixel can be simultaneously supplied with power through the power line 2290. In other words, the power applied to the switch 2300 and the thermoelectric element group 2110 is applied to at least one of the switch 2300 and the thermoelectric element group 2110, and the switch 2300 or the thermoelectric element group 2110 may output power.

On the other hand, the switch 2300 and the thermoelectric element group 2110 disposed in different driving pixels may have an electrical serial relationship.

One thermoelectric element group 2110 and the other thermoelectric element group 2110 disposed in different driving pixels may have an electrical serial relationship. Specifically, a power source applied to the first thermoelectric element group 2111 disposed in the first driving pixel 2201 is connected to the second thermoelectric element group 2111 via the second thermoelement group 2111, May be applied to the thermoelectric element group 2113.

Similarly, one switch 2300 and the other switch 2300 disposed in different driving pixels may have an electrical serial relationship. That is, the power supplied to the first switch 2301 disposed in the first driving pixel 2201 is applied to the second switch 2303 of the second driving pixel 2203 via the first switch 2301 .

In addition, the switch 2300 and the thermoelectric element group 2110 disposed in different driving pixels may have an electrical serial relationship. That is, a power source applied to the first switch 2301 disposed in the first driving pixel 2201 is connected to the second thermoelectric element group 2113 of the second driving pixel 2203 via the first switch 2301 . That is, a power source applied to the first thermoelectric element group 2111 disposed in the first driving pixel 2201 is connected to the second switching element 2203 of the second driving pixel 2203 through the first thermoelectric element group 2111, (2303).

For such an electrical serial relationship, a connection line 2500 may be provided.

Referring to FIG. 37, at least two thermoelectric element groups 2110 may be electrically connected by a connection line 2500.

The connection line 2500 electrically connects the switch 2300 of one drive pixel, the thermoelectric element group 2110 corresponding to the switch 2300, the switch 2300 of the other drive pixel and the thermoelectric element group 2110 . Specifically, the connection line 2500 is in contact with the first switch 2301 of the first driving pixel 2201 and the first thermoelectric element group 2111, and at the same time, the second switch 2203 of the second driving pixel 2203, (2303) and the second thermoelectric element group (2113). Specifically, the connection line 2500 is in contact with the first switch 2301 of the first driving pixel 2201 and a portion of the first thermoelectric element group 2111 where power is outputted, and the second driving pixel 2203 The second switch 2303 of the first thermoelectric element group 2113 and the second thermoelectric element group 2113 of the second thermoelectric element group 2113 are supplied with power. Accordingly, the power output from the first driving pixel 2201 can be applied to the second driving pixel 2203.

On the other hand, among the plurality of thermoelectric element groups arranged in one direction so as to have a serial relation as described above, the one thermoelectric element group is provided with a separate power line 2292 which returns to the power source generation section, Power can be applied.

Based on such an electrical series relationship, a thermoelectric operation can be performed. Hereinafter, the thermoelectric conversion operation will be described in detail.

FIG. 38 is a diagram for illustrating a one-time thermoelectric operation according to an embodiment of the present application. FIG.

FIG. 39 is a diagram for illustrating a single thermoelectric operation according to an embodiment of the present application. FIG.

38 and 39, the power output from one driving pixel is transferred to the other driving pixel, and the thermoelectric element group 2110 arranged in the other driving pixel based on the power source can perform thermoelectric conversion. In addition, the execution of the thermoelectric action may be determined depending on whether the switch 2300 disposed in the driving pixel is electrically opened or closed.

38, a gate line 2250 is connected to the gate of the switch 2300 disposed in the one driving pixel, a data line 2270 is connected to the input terminal of the switch 2300, A connection line 2500 may be in contact with the output end. In addition, a connection line 2500 for contacting the power line or the connection line for supplying power and the power source for the other part may be contacted to a part of the thermoelectric element group 2110 disposed in the one driving pixel.

Accordingly, whether or not the switch 2300 of the one-driving pixel is electrically opened or closed can be determined based on the gate signal and the data signal applied to the one driving pixel. In other words, it is possible to control whether the switch 2300 is electrically opened or closed for each driving pixel by controlling the gate signal and the data signal applied to the driving pixel. More specifically, when the gate signal and the data signal are simultaneously applied to the one driving pixel, the switch 2300 can be electrically opened.

In this case, when the switch 2300 of one driving pixel is electrically opened, the thermoelectric element group 2110 of the one driving pixel does not perform thermoelectric conversion, and conversely, when the switch 2300 is electrically closed, the thermoelectric element group 2110 ) Can perform a thermoelectric action. This can be caused by a phenomenon in which the power is concentrated and flows to the switch 2300 having a relatively low resistance as compared with the thermoelectric element group 2110 by electrically opening the switch 2300. That is, when the second switch 2303 of the second driving pixel 2203 is electrically opened, the power outputted through the first connection line 2500 of the first driving pixel 2201 is the same as the power of the second switch 2303 And when the second switch 2303 of the second driving pixel 2203 is electrically opened, the second thermoelectric element group 2113 is applied to the second thermoelectric element group 2113, Can be performed.

Referring again to FIG. 36, the one driving pixel may further include a switch 2300 having an electrical serial relationship with the thermoelectric element group 2110. That is, the first driving pixel 2201 may be electrically connected to a cutoff switch 2305 at a portion of the first thermoelectric element group 2111 to which power is applied. Specifically, the input terminal of the cutoff switch 2305 is connected to a power line or a connection line for transmitting power, and the output terminal may be electrically connected to a power receiving portion of the thermoelectric element group 2110.

In this case, whether the disconnecting switch 2305 is electrically opened or closed can be performed in an opposite operation to whether the first switch 2301 is electrically opened or closed. For example, when the first switch 2301 is electrically opened, the cutoff switch 2305 is electrically closed, and when the first switch 2301 is electrically closed, the cutoff switch 2305 is electrically opened . For example, the gate of the blocking switch 2305 is electrically connected to the output terminal of the first switch 2301, and the gate of the blocking switch 2305 and the output terminal of the first switch 2301 are connected to the inverter inverters may be provided to perform operations opposite to each other. However, the first switch 2301 and the disconnecting switch 2305 may have opposite electrical opening and closing states in a manner not limited to the above example.

Accordingly, when the first switch 2301 is electrically closed, the first thermoelectric element group 2111 can perform a thermoelectric action. Specifically, when the first switch 2301 is electrically closed, the cutoff switch 2305 is electrically opened to apply power to the first thermoelectric element group 2111, so that the first thermoelectric element group 2111 Is able to perform a thermoelectric action.

Conversely, when the first switch 2301 is electrically opened, the first thermoelectric element group 2111 can not perform a thermoelectric action. Specifically, when the first switch 2301 is electrically opened, the cutoff switch 2305 is electrically closed so that power is not applied to the first thermoelectric element group 2111, 2111 can not perform the thermoelectric action.

As shown in Fig. 39, when the shutoff switch 2305 is further disposed, the thermoelectric operation can be more stable for each driving pixel. By disposing the cutoff switch 2305, the power applied to the thermoelectric element group 2110 can be completely shut off. Specifically, when the first switch 2301 is electrically opened, a power leakage from the power applied to the first switch 2301 may be applied to the first thermoelectric element group 2111. Accordingly, the first thermoelectric element group 2111 can unintentionally perform thermoelectric conversion. Since the leakage power is cut off by disposing the cutoff switch 2305, the first thermoelectric element group 2111 does not perform an unintended thermoelectric action. As a result, the thermoelectric conversion of the thermoelectric element group 2110 can be performed stably by the provision of the cutoff switch 2305.

Hereinafter, control of the magnitude of the thermal sensation and the polarity of the thermal sensation will be described. In order to control the magnitude of the thermal sensation and the polarity of the thermal sensation, the control method of the first embodiment described above can be applied.

First, control of the magnitude of driving power applied to the thermoelectric element group for controlling the magnitude of the thermal sensation will be described. As described above, the control of the driving power source size can be performed by control over overlapping time and control over a plurality of frames. However, in the first embodiment, the number or time of the gate signal and the data signal applied to the driving pixel is proportional to the number or time of the gate signal and the data signal applied to the driving pixel, The control method of the second embodiment is different from the driving method in that the number of times or time of the output of the driving power is increased in proportion to the number or time of the gate signal and the data signal applied to the driving pixel, When the number or time of the gate signal and the data signal increases, the number or time of output of the driving power may tend to decrease.

First, the control of the overlapping time will be described.

The time of the driving power applied to the thermoelectric element group can be controlled by controlling the overlap time of the signal applied to the switch to control the magnitude of the thermal sensation. That is, by controlling the time at which the data signal applied to the switch arranged for each driving pixel overlaps the gate signal and controlling the time of the driving power applied to the thermoelectric element group, Can be adjusted.

As the overlapping time becomes longer, the time for applying the driving power to the thermoelectric element group is shortened, so that the magnitude of the heat sensation provided to the user by the thermoelectric element group is reduced. In addition, the above control can be caused by an increase in the amount of heat sensation provided to the user by the thermoelectric element group as the time for which the driving power is applied to the thermoelectric element group becomes longer as the overlap time becomes shorter.

That is, the magnitude of the driving power outputted for each driving pixel can be controlled by controlling the overlapping time of the signal applied to each pixel and the power source.

Hereinafter, a plurality of frame control will be described.

As described above, the size of the heat sensation can be controlled by dividing the frame into a plurality of frames for constituting the heat sensation providing surface and controlling the number of driving power sources output from the driving pixels for a plurality of frames. Specifically, to control the number of frames in which the driving power is output among the plurality of frames, a signal applied to the corresponding driving pixel may be controlled for each frame. That is, the number of data signals and gate signals applied to the driving pixel during the plurality of frames can be controlled based on the magnitude of the thermal sensation provided to the user by the thermoelectric element group of the thermoelectric region corresponding to the driving pixel .

Specifically, as the number of frames to which a data signal and a gate signal are applied to a driving pixel among a plurality of frames by a switch disposed for each driving pixel is increased, the number of times the driving power is applied to the thermoelectric element group correspondingly decreases, Can be reduced. On the other hand, as the number of frames in which the data signal and the gate signal are applied to the driving pixel among the plurality of frames by the switch arranged for each driving pixel decreases, the number of times the driving power is applied to the thermoelectric element group increases correspondingly, Can be increased.

Hereinafter, the polarity control for each driving pixel will be described.

As described above, the polarity of the driving power outputted from the thermoelectric element group can be performed by directly controlling the polarity of the driving power applied to the thermoelectric element group.

In this case, a driving control element for controlling the polarity connected in series to the thermoelectric element group may be provided. In other words, a drive control element for controlling the polarity may be provided at the position of the cutoff switch shown in Fig. 39, or a drive control element for controlling the polarity connected in series to the cutoff switch may be provided. The drive control element for controlling the polarity may be an H circuit.

As described above, the polarity control unit may further include a polarity control unit for controlling the operation of the driving control element, and the polarity control unit may control the polarity of the driving power applied to the thermoelectric element group The polarity can be controlled.

In the driving power supply control method and the 2D heating sensation providing apparatus using the driving power control method according to the present invention, the steps constituting the respective embodiments are not essential, and therefore, each embodiment can selectively include the above-described steps. Moreover, each step constituting each embodiment is not necessarily performed according to the order described, and the step described later may be performed before the step described earlier. It is also possible that each step is repeatedly performed during operation.
