As shown in FIG. 1, the touch screen may include a touch screen panel 100, a display panel 200, a substrate 300, and a pressure detection module 400. The touch screen may include a touch of an object such as a finger The position or pressure can be detected using an input-based capacitance change. The touch screen may include all of the above components, but may be implemented in a form including only some of them. The touch position and touch pressure detection method of the touch screen panel 100 shown in FIG. 1 will be described in detail below.

2A is a schematic view of a capacitive touch sensor panel 100 included in a touch screen used in a mobile terminal according to the present invention. 2A, the touch sensor panel 100 includes a touch sensor 10 including a plurality of driving electrodes TX1 to TXn and a plurality of receiving electrodes RX1 to RXm, A driving unit 12 for applying driving signals to the plurality of driving electrodes TX1 to TXn and a sensing unit 12 for sensing information including a capacitance change amount that varies depending on a touch on the touch surface from the plurality of receiving electrodes RX1 to RXm And a sensing unit 11 for receiving a signal and detecting a touch and a touch position.

As shown in FIG. 2A, the touch sensor 10 may include a plurality of driving electrodes TX1 to TXn and a plurality of receiving electrodes RX1 to RXm. 2A, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm of the touch sensor 10 are shown as an orthogonal array. However, the present invention is not limited to this, The electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm can have any number of dimensions including the diagonal, concentric and three-dimensional random arrangement, and the like and their application arrangements. Here, n and m are positive integers and may be the same or different from each other, and the size may be changed according to the embodiment.

The plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be arranged to cross each other. The driving electrode TX includes a plurality of driving electrodes TX1 to TXn extending in a first axis direction and a receiving electrode RX includes a plurality of receiving electrodes extending in a second axis direction intersecting the first axis direction RX1 to RXm).

7A and 7B, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm in the touch sensor 10 according to the embodiment of the present invention are formed in the same layer . For example, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed on a top surface of a display module 200 to be described later.

Alternatively, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed on different layers as shown in FIG. 7C. For example, one of the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed on the upper surface of the display module 200 and the other may be formed on the lower surface of the cover, (Not shown).

A plurality of drive electrodes (TX1 to TXn) and a plurality of receiving electrodes (RX1 to RXm) is a transparent conductive material (e.g., tin oxide (SnO ₂₎ and indium oxide _{(In 2 O 3) ITO (} Indium Tin made of such Oxide) or ATO (antimony tin oxide)). However, this is merely an example, and the driving electrode TX and the receiving electrode RX may be formed of another transparent conductive material or an opaque conductive material. For example, the driving electrode TX and the receiving electrode RX may include at least one of silver ink, copper, nano silver, and carbon nanotube (CNT) . In addition, the driving electrode TX and the receiving electrode RX may be realized by a metal mesh.

The driving unit 12 may apply a driving signal to the driving electrodes TX1 to TXn. In an embodiment of the present invention, the driving signal may be sequentially applied to one driving electrode at a time from the first driving electrode TX1 to the nth driving electrode TXn. This application of the driving signal can be repeated again. This is merely an example, and driving signals may be simultaneously applied to a plurality of driving electrodes according to an embodiment.

The sensing unit 11 acquires information on the electrostatic capacitance Cm generated between the driving electrodes TX1 to TXn and the receiving electrodes RX1 to RXm to which the driving signal is applied through the receiving electrodes RX1 to RXm And the touch position and the touch position can be detected by receiving the sensing signal. For example, the sensing signal may be a signal in which a driving signal applied to the driving electrode TX is coupled by a capacitance Cm: 14 generated between the driving electrode TX and the receiving electrode RX. The process of sensing the driving signal applied from the first driving electrode TX1 to the nth driving electrode TXn through the receiving electrodes RX1 to RXm may be referred to as scanning the touch sensor 10 .

For example, the sensing unit 11 may include a receiver (not shown) connected to each of the reception electrodes RX1 to RXm through a switch. The switch is turned on during a period of sensing the signal of the corresponding receiving electrode RX so that a sensing signal can be sensed from the receiving electrode RX at the receiver. The receiver may be comprised of an amplifier (not shown) and a feedback capacitor coupled between the negative input of the amplifier and the output of the amplifier, i. E., The feedback path. At this time, the positive input terminal of the amplifier may be connected to the ground. In addition, the receiver may further include a reset switch connected in parallel with the feedback capacitor. The reset switch can reset the conversion from current to voltage performed by the receiver. A negative input terminal of the amplifier may be connected to the corresponding receiving electrode RX to receive a current signal including information on the capacitance Cm, and integrate the current signal to convert the voltage into a voltage. The sensing unit 11 may further include an analog-to-digital converter (ADC) for converting the integrated data to digital data through the receiver. The digital data may then be input to a processor (not shown) and processed to obtain touch information for the touch sensor 10. The sensing unit 11 may be configured to include an ADC and a processor together with a receiver.

The control unit 13 may perform a function of controlling the operation of the driving unit 12 and the sensing unit 11. For example, the controller 13 may generate a driving control signal and transmit the driving control signal to the driving unit 12 so that the driving signal is applied to the driving electrode TX predetermined at a predetermined time. The control unit 13 generates a sensing control signal and transmits the sensing control signal to the sensing unit 11 so that the sensing unit 11 receives a sensing signal from the sensing electrode RX previously set at a predetermined time to perform a predetermined function can do.

2A, the driving unit 12 and the sensing unit 11 may constitute a touch detection device (not shown) capable of detecting whether the touch sensor 10 is touched or touched. The touch detection apparatus may further include a control section (13). The touch sensing device may be integrated on a touch sensing integrated circuit (IC), which is a touch sensing circuit, on a touch screen including the touch sensor 10. The driving electrode TX and the receiving electrode RX included in the touch sensor 10 are included in the touch sensing IC through a conductive trace and / or a conductive pattern printed on a circuit board And may be connected to the driving unit 12 and the sensing unit 11. The touch sensing IC may be placed on a circuit board on which a conductive pattern is printed, for example, a first printed circuit board (hereinafter, referred to as a first PCB). According to an embodiment, the touch sensing IC may be mounted on a main board for operating a touch screen.

As described above, a capacitance Cm of a predetermined value is generated at each intersection of the driving electrode TX and the reception electrode RX. When an object such as a finger is close to the touch sensor 10, Can be changed. In FIG. 1A, the capacitance may represent mutual capacitance (Cm). The sensing unit 11 senses such electrical characteristics and can detect whether the touch sensor 10 is touched and / or touched. For example, it is possible to detect the touch and / or the position of the touch on the surface of the touch sensor 10 having the two-dimensional plane including the first axis and the second axis.

More specifically, the position of the touch in the second axial direction can be detected by detecting the drive electrode TX to which the drive signal is applied when a touch to the touch sensor 10 occurs. Likewise, the position of the touch in the first axis direction can be detected by detecting the capacitance change from the received signal received through the receiving electrode RX when touching the touch sensor 10.

The operation of the touch sensor 10 for sensing the touch position has been described above based on the amount of mutual capacitance change between the driving electrode TX and the receiving electrode RX. However, the present invention is not limited to this, It is also possible to detect the touch position based on the amount of change in capacitance.

2B is a schematic view for explaining another embodiment of a touch sensor panel and an operation thereof according to another embodiment of the present invention. The touch sensor 10 may include a plurality of touch electrodes 30. The plurality of touch electrodes 30 may be arranged in a lattice pattern at regular intervals as shown in FIG. 7D, but the present invention is not limited thereto.

The driving control signal generated by the control unit 130 is transmitted to the driving unit 12 and the driving unit 12 applies the driving signal to the predetermined touch electrode 30 at a predetermined time based on the driving control signal. The sensing control signal generated by the control unit 13 is transmitted to the sensing unit 11. The sensing unit 11 senses the sensing signal from the touch electrode 30 preset at a predetermined time Receive input. At this time, the sensing signal may be a signal for the amount of change in self-capacitance formed on the touch electrode 30.

At this time, whether or not the touch sensor 10 is touched and / or the touch position is detected by the sensing signal sensed by the sensing unit 11. For example, since the coordinates of the touch electrode 30 are known in advance, it is possible to detect the touch of the object with respect to the surface of the touch sensor 10 and / or its position.

Although the driving unit 12 and the sensing unit 11 are divided into separate blocks for the sake of convenience, the operation of applying the driving signal to the touch electrode 30 and the sensing signal from the touch electrode 30 May be performed by one driving and sensing unit.

As shown in FIGS. 3A to 3C, the LCD panel includes a liquid crystal layer 250 including a liquid crystal cell, a first substrate layer 261 including electrodes at both ends of the liquid crystal layer 250, A second substrate layer 262 and a first polarizing layer 271 and a second substrate layer 262 on one surface of the first substrate layer 261 as a direction opposite to the liquid crystal layer 250 And a second polarizing layer 272.

These electrical components can operate to generate a controlled electric field to orient the liquid crystals located in the liquid crystal layer 250.

In addition, at least one of the first substrate layer 281 and the second substrate layer 283 may be formed of a bendable material such as a plastic.

OLED (Organic Light-Emitting Diode) panel is a self-luminous display panel that uses the principle that light is generated when electrons and holes are combined in an organic layer when current is applied to a fluorescent or phosphorescent organic thin film. Determine the color.

Specifically, OLEDs use the principle that an organic material emits light when an organic material is applied to glass or plastic and electricity is supplied. That is, when holes and electrons are injected into the anode and the cathode of the organic material, respectively, and then recombined with the light emitting layer, excitons having a high energy state are formed. When excitons fall into a state of low energy, energy is emitted, And to use the generated principle. At this time, the color of the light changes depending on the organic material of the light emitting layer.

In OLED, a line-driven PM-OLED (Passive-matrix Organic Light-Emitting Diode) and an AM-OLED (Active-matrix Organic Light-Emitting Diode) are used depending on the operation characteristics of the pixels constituting the pixel matrix exist. Since both of them do not require a backlight, the display module can be made very thin, the contrast ratio is constant according to the angle, and color reproducibility according to temperature is good. In addition, un-driven pixels are very economical in that they do not consume power.

In operation, the PM-OLED emits light only for a scanning time with a high current, and the AM-OLED maintains a light emission state for a frame time with a low current. Therefore, AM-OLED has better resolution than PM-OLED, it is advantageous to drive a large-area display panel and has low power consumption. In addition, since each element can be individually controlled by incorporating a thin film transistor (TFT), it is easy to realize a sophisticated screen.

It will be apparent to those skilled in the art that an LCD panel or an OLED panel may further include other configurations for performing the display function and may be altered or modified in various ways.

Specifically, when pressure is applied to the touch surface, the distance between the pressure sensor and the reference potential layer (not shown) located at the top, bottom or inside of the display panel 200A is changed, As the distance between the potential layers varies, the mutual capacitance between the third electrode 610 and the first electrode 620 can vary. As described above, the touch pressure can be detected according to the mutual capacitance between the third electrode 610 and the first electrode 620. In this case, when the touch sensor 10 includes at least one of the third electrode 610 and the fourth electrode 611, it is possible to detect the touch position and simultaneously detect the touch pressure. Also, the touch position can be detected in the first time interval, and the touch pressure can be detected in the second time interval different from the first time interval.

Thus, the touch pressure can be detected according to the mutual capacitance between the first electrode 620 and the second electrode 621. In this case, when the electrode used to drive the display panel 200A includes at least one of the first electrode 620 and the second electrode 621, the display panel 200A is driven and the touch pressure Can be detected. Also, the display panel 200A may be driven in the first time interval and the touch pressure may be detected in the second time interval different from the first time interval. At this time, when the touch sensor 10 includes at least one of the first electrode 620 and the second electrode 621, the touch position can be detected and the touch pressure can be detected. Also, the touch position can be detected in the first time interval, and the touch pressure can be detected in the second time interval different from the first time interval. At this time, the touch sensor 10 includes at least one of the first electrode 620 and the second electrode 621, and the electrode used for driving the display panel 200A is the first electrode 620, And the second electrode 621, it is possible to detect the touch position and the touch pressure while driving the display panel 200A. In addition, the touch position is detected in the first time interval, the touch pressure is detected in the second time interval different from the first time interval, and the touch pressure is detected in the third time interval different from the first time interval and the second time interval. Can be driven.

In addition, the pressure sensor of the touch screen shown in FIGS. 3A to 3F may be formed of at least one of the first electrode 620 and the second electrode 621. Specifically, when pressure is applied to the touch surface, the distance between the pressure sensor and the reference potential layer (not shown) located at the top, bottom or inside of the display panel 200A is changed, The capacitance between the first electrode 620 and the reference potential layer, that is, the self-capacitance of the first electrode 620 and / or the capacitance between the second electrode 621 and the reference potential layer, That is, the self-capacitance of the second electrode 621 can be changed. In this manner, the touch pressure can be detected according to the self-capacitance of the first electrode 620 and / or the second electrode 621. In this case, when the electrode used to drive the display panel 200A includes at least one of the first electrode 620 and the second electrode 621, the display panel 200A is driven, Pressure can be detected. Also, the display panel 200A may be driven in the first time interval and the touch pressure may be detected in the second time interval different from the first time interval.

More specifically, the reference potential layer can be formed on the bottom surface of the cover layer. Further, since the distance between the reference potential layer and the pressure sensor must be variable when applying pressure to the touch screen, a spacer layer may be disposed between the reference potential layer and the pressure sensor. In the touch screen shown in Figs. 3A and 3D, when the pressure sensor does not include the first electrode 620 or the second electrode 621, a reference potential layer may be disposed between the pressure sensor and the display panel 200A , Or may be disposed above the pressure sensor.

Further, the reference potential layer may be disposed under the display panel 200A. Specifically, the reference potential layer may be formed on a substrate, which will be described later, disposed below the display panel 200A, or the substrate itself may serve as a reference potential layer. In addition, the reference potential layer may be formed on the cover disposed on the upper portion of the substrate and disposed under the display panel 200A and performing the function of protecting the display panel 200A, or the cover itself may serve as the reference potential layer . The display panel 200A is bent when the pressure is applied to the touch screen, and the distance between the reference potential layer and the pressure sensor can be changed as the display panel 200A is warped. Further, a spacer layer may be disposed between the reference potential layer and the pressure sensor. Specifically, a spacer layer may be disposed between the display panel 200A and the substrate on which the reference potential layer is disposed or between the display panel 200A and the cover on which the reference potential layer is disposed. In addition, in the touch screen shown in Figs. 3A and 3D, if the pressure sensor does not include the first electrode 620 or the second electrode 621, the spacer layer may be disposed on the display panel 200A.

Alternatively, the reference potential layer may be disposed inside the display panel 200A. Specifically, the reference potential layer may be disposed on the upper surface or the lower surface of the first substrate layer 261, 281 of the display panel 200A, or on the upper surface or the lower surface of the second substrate layer 262, 283.

The touch screen for detecting the touch pressure using the electrode used for detecting the touch position and / or the electrode used for driving the display has been described in detail above.

Hereinafter, in order to detect the touch pressure in the touch screen according to the embodiment of the present invention, an example of disposing a separate electrode, which is different from the electrode used for detecting the touch position and the electrode used for driving the display, Let's take a closer look.

The pressure electrodes 450 and 460 for sensing a change in capacitance in a touch screen used in a mobile terminal according to the present invention are formed in the form of an electrode sheet and attached to a touch screen including the display module 200 and the substrate 300 . The display module 200 of the touch screen used in the mobile terminal according to the present invention may include a structure for driving the display panel 200A and the display panel 200A. Specifically, when the display panel 200A is an LCD panel, the display module 200 may include an LCD panel and a backlight unit (not shown), and a display panel control IC , A graphics control IC, and other circuitry.

Figures 4A-4F illustrate various embodiments of a touch screen including an electrode sheet.

The touch sensor panel 100 for detecting the touch position on the touch screen and the display module 200 may be laminated with an adhesive such as OCA (Optically Clear Adhesive). Accordingly, display color clarity, visibility, and light transmittance of the display module 200 that can be confirmed through the touch surface of the touch sensor can be improved.

 In the description with reference to Figs. 4A to 4F, it is illustrated that the touch sensor panel 100 is laminated and adhered with an adhesive on the display module 200, as shown in Figs. 3A and 3B, And may be disposed inside the display module 200 as shown in FIG. 4A and 4B illustrate that the touch sensor panel 100 covers the display module 200 but the touch sensor 10 is located inside the display module 200 and the display module 200 is made of glass A touch screen covered with a cover layer may also be used.

In a touch screen on which an electrode sheet can be applied, the substrate 300 is connected to a mounting space 310 where the circuit board and / or the battery for the operation of the touch screen can be placed together with the housing 320 as the outermost mechanism of the touch screen And so on. At this time, a central processing unit (CPU), a central processing unit (CPU), an application processor (AP), or the like may be mounted as a main board on the circuit board for operating the touch screen. The circuit board and / or the battery for the operation of the display module 200 and the touch screen are separated through the substrate 300, and the electrical noise generated in the display module 200 can be cut off.

The touch sensor 10 or the touch sensor panel 100 may be formed wider than the display module 200, the substrate 300 and the mounting space 310 on the touch screen, The housing 320 may be formed to enclose the display module 200, the substrate 300, and the circuit board together with the display unit 10.

The touch screen can detect the touch position through the touch sensor 10 and the electrode sheet 440 between the display module 200 and the substrate 300 to detect the touch pressure. At this time, the touch sensor 10 may be located inside or outside the display module 200.

Hereinafter, the configuration for detecting the pressure including the electrode sheet 440 will be collectively referred to as the pressure detecting unit 400. [ For example, in an embodiment, the pressure sensing unit 400 may include an electrode sheet 440 and / or a spacer layer 420.

As described above, the pressure detecting unit 400 includes a spacer layer 420 made of, for example, an airgap, which will be described in detail with reference to FIGS. 4B to 4F. The spacer layer 420 may be made of a shock-absorbing material according to an embodiment. The spacer layer 420 may be filled with a dielectric material according to embodiments.

As shown in FIG. 4B, the electrode sheet 440 may be disposed between the display module 200 and the substrate 300 on a touch screen. At this time, the touch screen may include a spacer layer disposed between the display module 200 of the touch screen and the substrate 300 to dispose the electrode sheet 440.

Hereinafter, the electrodes 450 and 460 for detecting the pressure are referred to as the pressure electrodes 450 and 460 so as to be clearly distinguished from the electrodes included in the touch sensor 10. At this time, since the pressure electrodes 450 and 460 are disposed on the rear surface rather than the front surface of the display panel, they may be formed of opaque material as well as a transparent material.

At this time, a frame 330 having a predetermined height along the rim of the upper portion of the substrate 300 may be formed to hold the spacer layer 420 on which the electrode sheet 440 is disposed. At this time, the frame 330 may be bonded to the touch sensor panel 100 with an adhesive tape (not shown). 4B, the frame 330 is formed on all the edges of the substrate 300 (e.g., four sides of a tetragonal shape), but the frame 330 may be formed on at least a part of the rim of the substrate 300 Three surfaces). According to an embodiment, the frame 330 may be integrally formed with the substrate 300 on the upper surface of the substrate 300. In an embodiment of the present invention, the frame 330 may be constructed of a material that is not elastic. In the embodiment of the present invention, when pressure is applied to the display module 200 through the touch sensor panel 100, the display module 200 may be bent together with the touch sensor panel 100, The magnitude of the touch pressure can be detected even if there is no deformation of the mold body.

4C is a cross-sectional view of a touch screen including a pressure electrode of an electrode sheet according to an embodiment of the present invention. Although the pressure electrodes 450 and 460 are shown separate from the electrode sheet 440 in Figure 4c and some of the following figures, this is for illustrative convenience only and the pressure electrodes 450 and 460 may be included in the electrode sheet 440 have. 4C, the electrode sheet 440 including the pressure electrodes 450 and 460 according to the embodiment of the present invention may be disposed on the substrate 300 as the spacer layer 420.

The pressure electrode for pressure detection may include a first electrode 450 and a second electrode 460. At this time, one of the first electrode 450 and the second electrode 460 may be a driving electrode and the other may be a receiving electrode. A driving signal may be applied to the driving electrode and a sensing signal may be obtained through the receiving electrode. When a voltage is applied, mutual capacitance may be generated between the first electrode 450 and the second electrode 460.

4D is a cross-sectional view of the touch screen shown in FIG. The lower surface of the display module 200 may have a ground potential for noise shielding. When pressure is applied to the surface of the touch sensor panel 100 through the object 500, the touch sensor panel 100 and the display module 200 may be bent or pressed. The distance d between the ground potential plane and the pressure electrodes 450 and 460 can be reduced to d '. In this case, as the distance d decreases, the fringing capacitance is absorbed to the lower surface of the display module 200, so that the mutual capacitance between the first electrode 450 and the second electrode 460 can be reduced have. Accordingly, the magnitude of the touch pressure can be calculated by acquiring the amount of decrease in mutual capacitance in the sensing signal obtained through the receiving electrode.

In FIG. 4D, the lower surface of the display module 200 is the ground potential, that is, the reference potential layer. However, the reference potential layer may be disposed inside the display module 200. In this case, when pressure is applied to the surface of the touch sensor panel 100 through the object 500, the touch sensor panel 100 and the display module 200 may be bent or pressed. Accordingly, the distance between the reference potential layer disposed in the display module 200 and the pressure electrodes 450 and 460 varies, and thus the capacitance change amount is obtained from the sensing signal acquired through the receiving electrode, and the magnitude of the touch pressure is calculated .

In the touch screen to which the electrode sheet 440 according to the embodiment of the present invention is applied, the display module 200 may be bent or pressed according to a touch to apply pressure. The display module 200 can be bent or pressed to show a deformation according to a touch. The position where the display module 200 is deformed when the display module 200 is bent or pressed may not coincide with the touch position, but the display module 200 may exhibit warping at least at the touch position. For example, when the touch position is close to the edge and the edge of the display module 200, the position where the display module 200 is bent or pushed to the greatest degree may be different from the touch position, It is possible to indicate warping or pressing.

At this time, the upper surface of the substrate 300 may also have a ground potential for noise shielding. 5 illustrates a cross section of an electrode sheet according to an embodiment of the present invention. 5A, a cross-sectional view of the electrode sheet 440 including the pressure electrodes 450 and 460 is shown attached to the substrate 300 or the display module 200. As shown in FIG. Since the pressure electrodes 450 and 460 are positioned between the first insulating layer 470 and the second insulating layer 471 in the electrode sheet 440, the pressure electrodes 450 and 460 are disposed between the substrate 300 and the display module 200, Can be prevented from being short-circuited. Also, depending on the type and / or implementation of the touch screen, the substrate 300 or the display module 200 to which the pressure electrodes 450 and 460 are attached may not exhibit a ground potential or may exhibit a weak ground potential. In this case, the touch screen according to the embodiment of the present invention may further include a ground electrode (not shown) between the substrate 300 or the display module 200 and the insulating layer 470. According to an embodiment, another insulating layer (not shown) may further be provided between the ground electrode and the substrate 300 or the display module 200. At this time, the ground electrode (not shown) can prevent the magnitude of capacitance generated between the first electrode 450 and the second electrode 460, which are pressure electrodes, from becoming too large.

4E illustrates a case where an electrode sheet 440 including pressure electrodes 450 and 460 is formed on the lower surface of the display module 200 according to an embodiment of the present invention. At this time, the substrate 300 may have a ground potential. Accordingly, as the touch surface of the touch sensor panel 100 is touched, the distance d between the substrate 300 and the pressure electrodes 450 and 460 decreases. As a result, the distance between the first electrode 450 and the second electrode 460). ≪ / RTI >

The first electrode 450 and the second electrode 460 shown in FIG. 5 are formed of a plurality of electrodes in the shape of a rhombus in the form that the first electrode 450 and the second electrode 460 are formed on the same layer . Here, the plurality of first electrodes 450 are connected to each other in the first axis direction, and the plurality of second electrodes 460 are connected to each other in the second axis direction orthogonal to the first axis direction. 450 and the second electrode 460 may be formed such that a plurality of diamond-shaped electrodes are connected to each other through a bridge so that the first electrode 450 and the second electrode 460 are insulated from each other. In addition, the first electrode 450 and the second electrode 460 shown in FIG. 5 may be composed of electrodes of the type shown in FIG. 9B.

The first electrode 450 and the second electrode 460 may be formed in different layers according to an embodiment to form an electrode layer. 5B illustrates a cross-section of the first electrode 450 and the second electrode 460 formed on different layers. 5B, the first electrode 450 is formed on the first insulating layer 470 and the second electrode 460 is formed on the first electrode 450, Layer 471 as shown in FIG. According to an embodiment, the second electrode 460 may be covered with a third insulating layer 472. That is, the electrode sheet 440 may include a first insulating layer 470 to a third insulating layer 472, a first electrode 450, and a second electrode 460. At this time, the first electrode 450 and the second electrode 460 are located on different layers, so that the first electrode 450 and the second electrode 460 overlap each other. For example, the first electrode 450 and the second electrode 460 may be formed similar to the pattern of the driving electrode TX and the receiving electrode RX arranged in the MXN structure, as shown in FIG. 9C . At this time, M and N may be natural numbers of 1 or more. Alternatively, the first electrode 450 and the second electrode 460 in the shape of a rhombus may be located on different layers, respectively.

It is exemplified that the touch pressure is detected from the change of mutual capacitance between the first electrode 450 and the second electrode 460. However, the electrode sheet 440 may be configured to include only one of the first electrode 450 and the second electrode 460, in which case one pressure electrode and the ground layer (the display module 200) The substrate 300, or the reference potential layer disposed in the display module 200), that is, the magnitude of the electrostatic capacitance, to detect the magnitude of the touch pressure. At this time, a drive signal is applied to the one pressure electrode, and a change in magnetic capacitance between the pressure electrode and the ground layer can be sensed from the pressure electrode.

For example, the pressure electrode included in the electrode sheet 440 in FIG. 4C may include only the first electrode 450. At this time, depending on the distance between the display module 200 and the first electrode 450, The magnitude of the touch pressure can be detected from the capacitance change between the first electrode 450 and the display module 200. The capacitance d between the display module 200 and the first electrode 450 may increase as the touch pressure increases because the distance d decreases as the touch pressure increases. This can be equally applied to the embodiment related to FIG. 4E. At this time, the pressure electrode need not have a comb-shaped or triangular shape necessary for increasing mutual capacitance change detection accuracy, and any one of the first electrode 450 and the second electrode 460 may be formed on one plate , A rectangular plate) shape, and the other electrode may be arranged in a lattice pattern at regular intervals.

5C illustrates a cross-sectional view of the electrode sheet 440 including only the first electrode 450. FIG. The electrode sheet 440 including the first electrode 450 may be disposed on the substrate 300 or the display module 200, as illustrated in FIG. 5 (c).

4F illustrates the case where the pressure electrodes 450 and 460 are formed on the upper surface of the substrate 300 and the lower surface of the display module 200 in the spacer layer 420. The electrode sheet may include a first electrode sheet 440-1 including a first electrode 450 and a second electrode sheet 440-2 including a second electrode 460. [ At this time, either one of the first electrode 450 and the second electrode 460 may be formed on the substrate 300, and the other one may be formed on the lower surface of the display module 200. 4F illustrates that the first electrode 450 is formed on the substrate 300 and the second electrode 460 is formed on the lower surface of the display module 200.

When pressure is applied to the surface of the touch sensor panel 100 through the object 500, the touch sensor panel 100 and the display module 200 may be bent or pressed. Accordingly, the distance d between the first electrode 450 and the second electrode 460 can be reduced. In this case, the mutual capacitance between the first electrode 450 and the second electrode 460 may increase as the distance d decreases. Accordingly, it is possible to calculate the magnitude of the touch pressure by acquiring the increase amount of mutual capacitance in the sensing signal obtained through the receiving electrode. In this case, since the first electrode 450 and the second electrode 460 are formed on different layers in FIG. 4F, the first electrode 450 and the second electrode 460 need not have a comb-like shape or a trident shape A plurality of first electrodes 450 and a plurality of second electrodes 460 may be arranged in a grid pattern at regular intervals as shown in FIG. 9D, .

5D illustrates a first electrode sheet 440-1 including a first electrode 450 and a second electrode sheet 440-1 attached on the substrate 300 and including a second electrode 460. [ 2) is attached to the display module 200. FIG. The first electrode sheet 440-1 including the first electrode 450 may be disposed on the substrate 300, as illustrated in FIG. 5 (d). In addition, the second electrode sheet 440-2 including the second electrode 460 may be disposed on the lower surface of the display module 200.

5 (a), when the substrate 300 or the display module 200 to which the pressure electrodes 450 and 460 are attached does not exhibit the ground potential or exhibits a weak ground potential, as shown in Fig. 5 the electrode sheet 440 in FIGS. 4A to 4D may include a ground electrode (not shown) between the substrate 300 or the display module 200 and the first insulation layers 470, 470-1 and 470-2 . At this time, the electrode sheet 440 may further include an additional insulation layer (not shown) between the ground electrode (not shown) and the substrate 300 or the display module 200.

The pressure electrodes 450 and 460 for sensing capacitance variation on the touch screen may be formed directly on the display panel 200A. 6A to 6C are cross-sectional views illustrating embodiments of pressure electrodes 450 and 460 formed directly on various display panels 200A.

6A shows pressure electrodes 450 and 460 formed on a display panel 200A using an LCD panel. Specifically, as shown in FIG. 6A, the pressure electrodes 450 and 460 may be formed on the bottom surface of the second substrate layer 262. In this case, although the second polarizing layer 272 is omitted in FIG. 6A, the second polarizing layer 272 may be formed between the pressure electrodes 450 and 460 and the back light unit 275, or between the pressure electrodes 450 and 460 and the second substrate layer 262 Polarizing layer 272 may be disposed. When the touch pressure is detected based on the amount of mutual capacitance change when a pressure is applied to the touch screen, a driving signal is applied to the driving electrode 450, a reference potential layer 300 spaced apart from the pressure electrodes 450 and 460, From the receiving electrode 460, an electrical signal including information on a capacitance that varies with a change in distance from the pressure electrodes 450 and 460. A driving signal is applied to the pressure electrodes 450 and 460 and a distance between the reference potential layer 300 separated from the pressure electrodes 450 and 460 and the pressure electrodes 450 and 460 From the pressure electrodes (450, 460), an electrical signal containing information on the capacitance that changes with the change.

Next, FIG. 6B shows the pressure electrodes 450 and 460 formed on the lower surface of the display panel 200A using the OLED panel (in particular, the AM-OLED panel). Specifically, the pressure electrodes 450 and 460 may be formed on the lower surface of the second substrate layer 283. At this time, the method of detecting the pressure is the same as that described in Fig. 6A.

Next, FIG. 6C shows the pressure electrodes 450 and 460 formed in the display panel 200A using the OLED panel. Specifically, the pressure electrodes 450 and 460 may be formed on the upper surface of the second substrate layer 283. At this time, the method of detecting the pressure is the same as that described in Fig. 6A.

Although the display panel 200A using the OLED panel has been described with reference to FIG. 6C, the pressure electrodes 450 and 460 may be formed on the upper surface of the second substrate layer 272 of the display panel 200A using the LCD panel It is possible.

6A to 6C, the pressure electrodes 450 and 460 are formed on the upper surface or the lower surface of the second substrate layers 272 and 283. However, the pressure electrodes 450 and 460 may be formed on the upper surface or the lower surface of the first substrate layers 261 and 281 .

For example, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed on a top surface of a display module 200 to be described later.

Also, as shown in FIG. 7C, the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed in different layers. For example, one of the plurality of driving electrodes TX1 to TXn and the plurality of receiving electrodes RX1 to RXm may be formed on the upper surface of the display module 200 and the other may be formed on the lower surface of the cover, (Not shown).

A plurality of drive electrodes (TX1 to TXn) and a plurality of receiving electrodes (RX1 to RXm) is a transparent conductive material (e.g., tin oxide (SnO ₂₎ and indium oxide _{(In 2 O 3) ITO (} Indium Tin made of such Oxide) or ATO (antimony tin oxide)). However, this is merely an example, and the driving electrode TX and the receiving electrode RX may be formed of another transparent conductive material or an opaque conductive material. For example, the driving electrode TX and the receiving electrode RX may include at least one of silver ink, copper, nano silver, and carbon nanotube (CNT) . In addition, the driving electrode TX and the receiving electrode RX may be realized by a metal mesh.

Hereinafter, an object display method and a mobile terminal using the method according to the present invention will be described in detail.

According to the object display method of the present invention, an application using a touch pressure function can be displayed separately from an application not using the touch pressure function. Here, the term " touch pressure function " means a function capable of operating an application using the above-described touch pressure.

For example, when a touch pressure equal to or greater than a predetermined size is applied to a camera-related application, the photographing mode is changed. When a touch pressure equal to or larger than a predetermined size is applied, It may mean that the reproduction mode is changed when the touch pressure is applied. At this time, the camera, photo and music-related applications have touch pressure function.

In the present invention, " object " means a graphic element for a user interface displayed on a touch screen. The object may specifically mean an icon, but it is not limited thereto and may be a graphical element such as a folder, a menu, a thumbnail, and the like.

8 is a flowchart showing an object display method according to the present invention. First, the application information of the application installed in the mobile terminal is acquired (S1000), and an attribute value related to the touch pressure function is extracted from the obtained application information (S1010).

Here, the attribute value related to the touch pressure function indicates information on whether the corresponding application has the touch pressure function. For example, as shown in FIG. 10, if the attribute value is 2, information on whether or not the touch pressure function is present can be displayed. If there is an attribute value having the touch pressure function in the state of the attribute value 2, (S1030-1 to S1030-3, described below). If there is no attribute value having the touch pressure function, the first object is displayed (S1040). Here, the first object means a basic application for identifying a corresponding application. The application information may include only one object, but may include two or more objects.

 However, the present invention is not limited thereto and can be coded in various manners by those skilled in the art.

On the other hand, if there is an attribute value having a touch pressure function, the object corresponding to the extracted attribute value can be displayed on the touch screen, and the object corresponding to the extracted attribute value can be determined in various ways as described below have.

It is possible to change and display the basic (first) object included in the application information (S1030-1). For example, at least one of the shape, the size, the color, the brightness, and the saturation of the basic (first) object is changed and displayed so that the user can identify that the application has the touch pressure function.

In addition, a separate mark may be further displayed on the basic (first) object included in the application information (S1030-2). For example, a small mark P is displayed at the upper right or lower end of the basic (first) object so that the user can identify that the application has the touch pressure function.

In addition, a second object different from the basic (first) object included in the application information can be displayed (S1030-3). In this case, the application includes information about two or more objects, i.e., two or more icons. This allows the user to easily identify that the application has the touch pressure function.

FIG. 9 is a schematic view showing each step included in the flow chart of FIG. 8 divided by the performing subjects, and FIG. 10 shows an example of an attribute value.

Referring to FIG. 9, various applications are installed in a mobile terminal by a package manager (S1100). The application installed in the mobile terminal has application information (Application info) for maintenance and operation of the application, and the home launcher can extract the application information from each application (S1110).

In the application information extracted by the home runner, there is an object for identifying the application, and the home run destination displays the object on the touch screen (S1130), and builds an interface by which the user can execute or select the application.

At this time, if the home-run destination finds the user interface option attribute in the application information and the user interface option attribute does not exist (S1140-NO), the object included in the application is displayed as is. It is determined whether there is an attribute value having a touch pressure function (S1150). If there is an attribute value having the touch pressure function (S1150-YES), an object for displaying the object is generated and displayed on the touch screen (S1160) And displays the object (S1130).

At this time, attribute values having a user interface option attribute and a touch pressure function can be defined as shown in FIG. The constant 1200 may include none, splitActionBarwhenNarrow, and hasExtra3dUI, and its value 1210 may correspond to 0, 1, and 2, respectively. Here, the attribute value 0 indicates that there is no separate user interface option attribute, and the attribute value 1 and the attribute value 2 indicate that there is a separate user interface option attribute. In particular, the attribute value 2 indicates that it is possible to include information on the presence or absence of the attribute value having the touch pressure function in the state that there is a separate user interface option attribute. In the attribute value 2, If there is a value (S1150-YES), an object for displaying it is created and displayed on the touch screen. If there is no attribute value having the touch pressure function (S1150-NO), the basic object is displayed. On the other hand, the attribute value 1 indicates that the user interface option attribute can be divided with the separate user interface option attribute. For example, the user interface option attribute may be divided and placed in the form of a separate bar at the top or bottom of the touch screen, and the generated separate bar may be further divided into a top navigation area ) Or a bottom menu area. ≪ RTI ID = 0.0 >

FIG. 11 shows a configuration of a mobile terminal 1300 according to the present invention, and FIGS. 12 to 15 show a touch screen when various object display methods according to the present invention are implemented in a mobile terminal 1300. FIG.

11, the mobile terminal 1300 according to the present invention includes a touch screen 1310, a controller 1320, a storage unit 1330, an input unit 1340, an output unit 1350, and a communication unit 1360, .

The touch screen 1300 detects the touch position and the touch pressure of the touch applied by the user in the structure and operation described above.

The storage unit 1330 stores the operating system, contents, and various applications of the mobile terminal 1300. The input unit 1340 may be an input module for storing data including a microphone for receiving a user's voice and the output unit 1350 may be an output module such as a speaker for outputting voice or music of the other party. In addition, the communication unit 1360 may include a mobile communication module, a satellite communication module, a Bluetooth module, a Wi-Fi module, or a digital broadcasting module.

The controller 1320 performs functions of the mobile terminal 1300, not shown in FIG. 11, including the touch screen 1310, the storage unit 1330, the input unit 1340, the output unit 1350, and the communication unit 1360 And controls various modules to be used.

The controller 1320 also extracts attribute values associated with the touch pressure function from the application information of the application installed in the mobile terminal 1300. Then, an object corresponding to the extracted attribute value is controlled to be displayed on the touch screen 1310.

That is, as described above, if the attribute value indicating the touch pressure function is not detected from the application information of the application, the controller 1320 displays the basic (first) object directly on the touch screen 1310. The user can see that the basic (first) object of the application is displayed as it is and can recognize that the application does not have the touch pressure function. 12 shows a screen of the touch screen 1310 in which the application information does not include an attribute value indicating the touch pressure function and the basic (first) object is displayed as it is. The objects a1 to a11 displayed on the touch screen 1310 are basic (first) objects for identifying each application. This means that not all applications have a touch pressure function, and the user can instantly identify it.

Alternatively, if an attribute value indicating that the application has the touch pressure function is detected from the application information, the controller 1320 changes the basic (first) object in various manners as shown in FIGS. 13 to 15 Can be displayed on the touch screen 1310.

13, the controller 1320 may display and change at least one of the shape, size, color, brightness, saturation, and depth of the basic (first) object included in the application information.

Alternatively, the controller 1320 may identify the touch pressure function of the application in a manner that makes the object larger or brighter.

Alternatively, when the attribute value indicating that the application is an application using the touch pressure function is extracted, the controller 1320 can control to display a separate mark together with the basic (first) object included in the application information . Referring to FIG. 14, the applications a2, a4 and a9 using the touch pressure function are marked with a separate mark b1 at the upper right of the object. A separate mark b1 may be included in the application information of the application or may be stored in the storage unit 1330 of the mobile terminal 1300. The user can immediately recognize that only the application of a2, a4 and a9 indicated by the separate mark b1 can utilize the touch pressure function.

Alternatively, the controller 1320 may control to display the second object included in the application information if an attribute value indicating that the application is an application using the touch pressure function is extracted. At this time, it is preferable that the application information may include a separate second object together with the basic (first) object, and the second object is designed different from the basic (first) object. In other words, the second object may be different in shape, shape, size, color, lightness, saturation or depth from the basic (first) object. Referring to Fig. 15, a2, a4, and a9 that can utilize the touch pressure function among the installed applications are displayed, and a second object having a different shape from the basic (first) object (see Fig. 12) . The user can immediately identify that only the application of a2, a4 and a9, in which the second object distinguished from the basic (first) object is displayed, can use the touch pressure function.

In the above-described object display method, the object is displayed in a different manner based on the attribute value. Alternatively, the corresponding application information includes a flag for identifying the touch pressure function.
