Representative sensors among various sensors that may be included in the sensing unit 140 will be described in more detail.
First, the proximity sensor 141 refers to a sensor that detects the presence of an object approaching a predetermined detection surface, or the presence of an object in the vicinity of the detection surface, without mechanical contact by using electromagnetic force or infrared rays. The proximity sensor 141 may be disposed in an inner region of a display device or a proximity sensor 141 near the touch screen.
Examples of the proximity sensor 141 include a transmission type photoelectric sensor, a direct reflection type photoelectric sensor, a mirror reflection type photoelectric sensor, a high frequency oscillation type proximity sensor, a capacitive proximity sensor, a magnetic proximity sensor, and an infrared proximity sensor. In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change of the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.
On the other hand, for convenience of explanation, the act of recognizing that the object is located on the touch screen in proximity with no object touching the touch screen is referred to as "proximity touch & The act of actually touching an object on the screen is called a "contact touch. &Quot; The position at which the object is closely touched on the touch screen means a position where the object corresponds to the touch screen vertically when the object is touched. The proximity sensor 141 can detect a proximity touch and a proximity touch pattern (e.g., a proximity touch distance, a proximity touch direction, a proximity touch speed, a proximity touch time, a proximity touch position, have. Meanwhile, the control unit 180 processes data (or information) corresponding to the proximity touch operation and the proximity touch pattern sensed through the proximity sensor 141 as described above, and further provides visual information corresponding to the processed data It can be output on the touch screen. Further, the control unit 180 can control the display device 100 to process different operations or data (or information) according to whether the touch to the same point on the touch screen is a proximity touch or a contact touch .
The touch sensor senses proximity or contact of the object to the touch screen 151 using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, and a magnetic field type.
For example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen or a capacitance generated in a specific portion to an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, a capacitance at the time of touch, and the like where a touch object touching the touch screen is touched on the touch sensor. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch sensor.
Thus, when there is a touch input to the touch sensor, the corresponding signal (s) is sent to the touch controller. The touch controller processes the signal (s) and transmits the corresponding data to the controller 180. Accordingly, the control unit 180 can know which area of the touch screen 151 is touched or the like. Here, the touch controller may be a separate component from the control unit 180, and may be the control unit 180 itself.
On the other hand, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen (or a touch key provided on the touch screen).

Touch can be sensed.
The ultrasonic sensor can recognize the position information of the object to be sensed by using ultrasonic waves. Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.
The camera 121 includes at least one of a camera sensor (for example, a CCD, a CMOS, etc.), a photo sensor (or an image sensor), and a laser sensor.

The photosensor can be laminated to the display element, which is adapted to scan the movement of the object to be detected proximate to the touch screen. More specifically, the photosensor mounts photo diodes and TRs (Transistors) in a row / column and scans the contents loaded on the photosensor using an electrical signal that varies according to the amount of light applied to the photo diode. That is, the photo sensor performs coordinate calculation of the object to be sensed according to the amount of change of light, and position information of the object to be sensed can be obtained through the calculation.

The capacitance at the point where the distance from the object 300 to the object 300 in the entire sensing area of the touch sensor 151b may be C1 and the capacitance at the point where the distance from the object 300 to the object 300 is L2 C1), and the capacitance at the point where the distance from the object 300 is L3 (> L2) may be C3 (> C2). That is, the closer the object 300 is to the touch screen 151, the more the change in capacitance caused by the object 300 may increase.
Based on the capacitance characteristic shown in FIG. 3, the controller 180 analyzes the change pattern of capacitance caused by the object 300, and based on the analysis result, determines whether the received touch input is a proximity touch or a contact (E.g., xy coordinates), the distance, the area, and the touched time of the object 300. In addition,
4 is a conceptual diagram of an input device 200 according to an embodiment of the present invention, viewed from different directions.
Referring to FIG. 4, an input device 200 according to an exemplary embodiment of the present invention may include a body 210, a moving contact 220, a connecting portion 230, and a bonding portion 240.
4 (a) is a perspective view of an input device 200 according to an embodiment of the present invention, and FIG. 4 (b) is a bottom view of the input device 200 shown in FIG. And FIG. 4C is an exemplary side cross-sectional view of the input device 200 shown in FIG. 4A cut along the cutting line A-A '. For convenience of explanation, it is noted that the bonding portion 240 is omitted in Fig. 4 (b).
The body 210 may be in the form of a ring having a hole penetrating the center part vertically, as shown in the figure. 4, the shape of the ring of the body 210 is shown as being circular, but this is merely an example, and it is apparent to those skilled in the art that other than a circular shape, a rectangular ring or the like is possible. The body 210 is a body of the input device 200, in which the remaining components of the input device 200 are directly or indirectly coupled as will be described in more detail below.
A first conductive pattern 211 may be formed on the lower end of the body 210. The first conductive pattern 211 may be made of a conductive material capable of causing a change in capacitance to the touch sensor 151b of the touch screen 151 when the first conductive pattern 211 is positioned within a certain distance from the touch screen 151. [ For example, as the conductive material forming the first conductive pattern 211, a conductive polymer such as a metal conductor such as copper or poly (3,4-ethylenedioxythiophene) (PEDOT) may be used.
The first conductive pattern 211 is formed in an area and shape detectable by the touch screen 151 and can determine the position of the input device 200 to which the display device 100 is adhered and fixed to the touch screen 151 And the like. That is, the display device 100 may detect the first conductive pattern 211 that is in proximity to or in contact with the touch screen 151 to determine whether the input device 200 is adhered and fixed to the touch screen 151 . For example, the first conductive pattern 211 may be formed in a ring shape continuously extending along the lower end of the body 210, as shown in FIG. 4 (b).
The moving contact portion 220 is configured to move or rotate along at least one of three axes (x-axis, y-axis, and z-axis) by an external force (by a user). This mobile contact 220 converts the user input into a touch input. Specifically, the moving contact portion 220 is moved or rotated along at least one of the x-axis, the y-axis, and the z-axis by the user, and the display device 100 is moved or rotated in accordance with the movement or rotation of the moving contact 220 The screen state output from the touch screen 151 can be changed or a predetermined operation can be performed on the basis of the capacitance change of the touch screen 151 by the touch input.
The movable contact portion 220 may have a structure in which the upper and lower ends are exposed to the outside, as shown in FIG. An external force is applied by the user through the upper exposed portion of the moving contact 220 and the user input may be converted to a touch input to the touch screen 151 through the lower exposed portion of the moving contact 220 .
At this time, at least a part of the moving contact 220 (in particular, at least a part of the lower exposed portion) may be formed of a conductive material. The conductive material formed on at least a part of the moving contact portion 220 may be formed on the touch screen 151 in proximity to or in contact with the display device 100, such as a metal conductor or a conductive polymer, similarly to the first conductive pattern 211 described above. Is not particularly limited as long as it is a material capable of causing a capacitance change of a certain level or more.
4 (c), the lower end of the moving contact portion 220 may be formed to have a narrower width as the touch screen 151 is closer to the touch screen 151 Lt; / RTI > In addition, a contact member 221 made of the conductive material described above may be coupled to the lower end of the moving contact portion 220. In this case, the remaining portion of the moving contact 220 excluding the contact member 221 may be formed of a nonconductive material.
The connection portion 230 may physically connect the body 210 and the moving contact portion 220. Specifically, the connecting portion 230 may be formed of a material having a predetermined elasticity so that the moving contact portion 220 can move in three axial directions by an external force in a hole formed in the body 210. For example, the connecting portion 230 can be formed using rubber, silicon, electroactive polymer (EAP), a spring, or the like. For example, an electroactive polymer refers to a polymer that can shrink or relax within a predetermined range depending on the presence or size of an electric signal applied from the outside. For example, the larger the electric signal supplied to the electroactive polymer, the greater the shrinkage of the electroactive polymer. To this end, the input device 200 may further include a battery (not shown) capable of supplying power to the electroactive polymer. The user can vary the elasticity of the electroactive polymer by adjusting an electric signal supplied to the electroactive polymer by using a power control module (not shown) functionally coupled with the electroactive polymer and the battery.
When the connection portion 230 is formed of an elastic material, a part of the connection portion 230 may be contracted and another portion may be extended by an external force applied to the moving contact portion 220. When the external force to the moving contact part 220 disappears, the position of the moving contact part 220 can be returned to the center part of the body 210 by the elastic force of the connection part 230.
The adhesive portion 240 adhesively fixes the input device 200 to the touch screen 151. Specifically, the upper surface of the bonding portion 240 may be coupled to at least one of the lower end of the body 210 and the first conductive pattern 211, and the lower surface may be exposed to the outside so as to be bonded to the touch screen 151 . That is, the adhesive portion 240 may be disposed at the lower end of the body 210 to fix the body 210 so that the body 210 can be detachably attached to one area of the touch screen 151.
The adhesive portion 240 may be any material such as a gecko adhesive or the like that has a certain range of adhesive force so that an object can be attached to another object and can be repeatedly attached and detached more than a predetermined number of times.
In FIG. 4, the first conductive pattern 211 and the adhesive portion 240 are shown as being vertically abutted with each other with the same width, but this is merely an example, and it should be understood that various modifications are possible.
FIG. 5 shows a modification of the first conductive pattern 211 included in the input device 200 according to an embodiment of the present invention. To facilitate understanding, the description will be made with reference to a bottom view as shown in Fig. 4 (b).
Referring to FIG. 5A, the first conductive pattern 211 and the adhesive portion 240 may have different widths, unlike FIGS. 4B and 4C. For example, when the first conductive pattern 211 and the bonding portion 240 are both circular, the radius of the bonding portion 240 may be smaller than the radius of the first conductive pattern 211, and vice versa Do. If the radius of the bonding portion 240 is smaller than the radius of the first conductive pattern 211, a portion of the lower end of the first conductive pattern 211 may be exposed to the outside by the difference between the two radii.
Referring to FIG. 5B, the first conductive pattern 211 may include a plurality of sub patterns 211a to 211d that are spaced apart from each other. In addition, a bonding portion 240 may be formed at a portion where the sub patterns 211a to 211d are spaced apart from each other.
The display device 100 is configured such that the touched area of the touch screen 151 is divided into the first conductive pattern 211 as shown in Figs. 4C, 5A and 5B It can be determined that the input device 200 is attached to the touch screen 151 only when it has a corresponding specific shape and / or size.
6 shows an exemplary use of an input device 200 according to an embodiment of the present invention.
First, FIG. 6A illustrates an unoperated state of the input device 200. FIG. 6A, in the unoperated state, the moving contact 220 of the input device 200 can be held at the designed position of the body 210 (e.g., the center of the hole).
On the other hand, the first conductive pattern 211 can form a capacitance equal to or larger than the reference value Cr in a region of the touch screen 151 close to the first conductive pattern 211. For example, when the shape of an area in which the capacitance is greater than or equal to the reference value Cr among the entire area of the touch screen 151 is compared with a predetermined shape to match each other, the display device 100 displays the touch screen 151 151 in a state in which they are adhered to each other. In a state where the input device 200 is attached to the touch screen 151, the lower end of the moving contact portion 220 may be in contact with the touch screen 151 or may be spaced apart by a predetermined distance L as shown in the drawing . In this case, the distribution curve of the capacitance induced by the moving contact portion 220 may be located in the center of the distribution curve of the capacitance induced by the first conductive pattern 211.
6B illustrates a state in which the moving contact portion 220 of the input device 200 is moved to the left by the user. As described above, the connection portion 230 is formed into an elastic chamber so that, depending on the movement of the moving contact portion 220, a portion can be contracted and another portion can be extended.
As the moving contact portion 220 moves to the left, the distribution curve of the capacitance induced to the moving contact portion 220 can also be moved to the left.
6C illustrates a state in which the moving contact portion 220 of the input device 200 is pushed downward in the vertical direction while being moved to the left as shown in FIG. 6B. In this case, the moving contact 220 is positioned (e.g., in contact) closer to the touch screen 151 than in FIGS. 6A and 6B, and the magnitude of the capacitance induced by the moving contact 220 .
The display device 100 is configured such that in the region between the distribution curves of the capacitance induced by the first conductive pattern 211 the capacitance (by the moving contact 220) above the reference value Cr It is possible to perform a predetermined operation based on the coordinate value of the point at which it occurred. For example, in a case where the Internet icon is displayed in the coordinates of the point at which the electrostatic capacity of the movable contact 220 has exceeded the reference value Cr, the display device 100 can execute the Internet application corresponding to the Internet icon.
Fig. 7 shows a modification of the input device 200 shown in Fig. 4 (c).
Referring to FIGS. 7A and 7B, the input device 200 may further include a pressure sensor 250 and a communication module 260.
The pressure sensor 250 can detect the pressure in the vertical direction applied to the moving contact 220. [ For example, a strain gauge may be used as the pressure sensor 250. The strain gauge is a sensor that measures stress and strain of a material by using "strain", that is, an effect that an external force acts on an object to cause deformation of the object. Strain refers to the degree of deformation or strain, and refers to the ratio of the length of an object stretched or shrunk to its original length when stretched or compressed.
The strain gauge measures the strain of the moving contact portion 220 based on a change in the electrical resistance corresponding to the minute deformation of the moving contact portion 220 according to the external force by the user and the communication module 260 measures the strain by the strain gauge To the display device 100, a signal corresponding to the strain of the moved contact portion 220. [ For example, the communication module 260 may be a wireless communication module, such as wireless fidelity, WiFi direct, infrared, Zigbee, Near field communications, Radio-Frequency IDentification, Bluetooth, UWB (E.g., UltraWideBand), or may receive data from the display device 100. The display device 100 may be connected to the display device 100 via a network.
Meanwhile, the pressure sensor 250 and the communication module 260 may be provided inside the moving contact portion 220 as shown in FIG. 7 (a). Alternatively, a plurality of pressure sensors 250 may be provided at portions of the body 210 that are connected to the connection unit 230, as shown in FIG. 7A. Of course, it should be understood that the communication module 260 may also be provided on one side of the component other than the mobile contactor 220. [
FIG. 8 illustrates a case where the connecting portion 230 of the input device 200 shown in FIG. 4C is made of an electroactive polymer.
Specifically, FIG. 8A illustrates a state in which no electrical signal is supplied to the connection unit 230, and FIG. 8B illustrates a state in which an electrical signal is supplied to the connection unit 230. FIG.
Referring to FIG. 8 (b), as the connection portion 230 expands (or expands) in response to an electrical signal, it has a greater elastic force than the state shown in FIG. 8 (a). That is, in a state in which the connection portion 230 is expanded, a force larger than that shown in Fig. 8 (a) must be applied to move the moving contact portion 220 by the same distance.
8 (a) and 8 (b), when the connection part 230 is made of an electroactive polymer, the elasticity of the connection part 230 can be controlled by adjusting an electric signal, There is an advantage that it is possible to operate the contact portion 220.
FIG. 9 is a conceptual view of an input device 200 according to another embodiment of the present invention, viewed from different directions.
Referring to FIG. 9, an input device 200 according to an exemplary embodiment of the present invention may include a body 210, a moving contact 220, a connecting portion 230, and a bonding portion 240.
9 (a) is a perspective view of an input device 200 according to an embodiment of the present invention, and FIG. 9 (b) is a bottom view of the input device 200 shown in FIG. 9 And FIG. 9C is an exemplary side cross-sectional view of the input device 200 shown in FIG. 9A cut along the cutting line B-B '. For convenience of explanation, it is noted that the bonding portion 240 is omitted in Fig. 9 (b).
The body 210 may be in the form of a ring having a hole penetrating the center part vertically, as shown in the figure. 9, the shape of the ring of the body 210 is shown as being circular, but this is merely an example, and it is apparent to those skilled in the art that other than a circular shape, a rectangular ring or the like is possible. The body 210 is a body of the input device 200, in which the remaining components of the input device 200 are directly or indirectly coupled as will be described in more detail below.
A first conductive pattern 211 may be formed on the lower end of the body 210. The first conductive pattern 211 may be made of a conductive material capable of causing a change in capacitance to the touch sensor 151b of the touch screen 151 when the first conductive pattern 211 is positioned within a certain distance from the touch screen 151. [ For example, as the conductive material forming the first conductive pattern 211, a conductive polymer such as a metal conductor such as copper or poly (3,4-ethylenedioxythiophene) (PEDOT) may be used.
The first conductive pattern 211 is formed in an area and shape detectable by the touch screen 151 and can determine the position of the input device 200 to which the display device 100 is adhered and fixed to the touch screen 151 And the like. That is, the display device 100 may detect the first conductive pattern 211 that is in proximity to or in contact with the touch screen 151 to determine whether the input device 200 is adhered and fixed to the touch screen 151 . For example, the first conductive pattern 211 may be formed in a ring shape continuously extending along the lower end of the body 210, as shown in FIG. 9 (b).
The moving contact portion 220 has a ball shape and has second conductive patterns 222a, 222b and 222c formed on the surface and / or inside thereof. The moving contact portion 220 is formed in advance in the hole defined by the connecting portion 230 And is configured to be able to rotate in an arbitrary direction according to an external force (by a user) in a predetermined range. In accordance with the rotational movement of the moving contact 220, an external force applied by the user to the moving contact 220 can be converted into a touch input.
Specifically, when the moving contact portion 220 of the ball shape is rotated by the user, the second conductive pattern 222a, 222b, 222c formed on the moving contact portion 220 causes the touch screen 151 to be caused The display device 100 can change the screen state output from the touch screen 151 or perform a predetermined operation based on the continuous change of the capacitance.
The movable contact portion 220 may have a structure in which the upper and lower ends are exposed to the outside, as shown in FIG. An external force is applied by the user through the upper exposed portion of the moving contact 220 and the user input may be converted to a touch input to the touch screen 151 through the lower exposed portion of the moving contact 220 .
The material of the second conductive patterns 222a, 222b and 222c of the moving contact part 220 is similar to the first conductive pattern 211 described above so as to be close to or in contact with the display device 100 such as a metal conductor or a conductive polymer, And is not particularly limited as long as it is a material capable of causing a capacitance change of a certain level or more on the touch screen 151 in a contact state. The remaining portion of the moving contact 220 excluding the second conductive patterns 222a, 222b, and 222c may be formed of a non-conductive material.
One side of the connection part 230 is connected to the body 210 and the other side can physically support the moving contact part 220 at a predetermined position. 9, the connecting part 230 according to the embodiment shown in FIG. 9 includes a moving contact part 220 such that the moving contact part 220 is rotatable in an arbitrary direction by an external force in a hole formed in the body 210 And can be fixed and supported. Specifically, the connection portion 230 may serve as a partition wall that restricts the moving range of the moving contact portion 220 in the three axial directions, thereby enabling rotational movement. That is, the connection part 230 has a shape that covers a predetermined length part up and down with respect to the center of the moving contact part 220, thereby preventing the moving contact part 220 from departing from the body 210, The guide member 220 can be guided to rotate within a predetermined space.
The adhesive portion 240 adhesively fixes the input device 200 to the touch screen 151. Specifically, the upper surface of the bonding portion 240 is coupled to at least one of the lower end of the body 210 and the first conductive pattern 211, and the lower surface thereof may be exposed to the outside so as to be adhered to the touch screen 151 have.
For example, a gecko adhesive may be used as the material for forming the bonding portion 240. The bonding portion 240 may have an adhesive force in a predetermined range so that an object can be attached to another object, Any material may be used.
9, the first conductive pattern 211 and the adhesive portion 240 are illustrated as being in contact with each other with the same width up and down, but this is merely an example, and it should be understood that various modifications are possible.
9 also includes a pressure sensor 250 and a communication module 260, similar to FIG. For example, the pressure sensor 250 may be disposed at a portion of the entire area of the connection portion 230 that abuts the mobile contact portion 220, and the communication module 260 may be disposed inside the body 210. The communication module 260 is provided with pressure information for the moving contact 220 measured by the pressure sensor 250 and the communication module 260 can transmit the wireless signal corresponding to the pressure information to the display device 100 have.
10 shows an exemplary use of an input device 200 according to an embodiment of the present invention.
10 (a) illustrates an unoperated state of the input device 200. FIG. 10A, in the unoperated state, the moving contact 220 of the input device 200 can be held at the designed position of the body 210 (e.g., the center of the hole).
On the other hand, the first conductive pattern 211 can form a capacitance equal to or larger than the reference value Cr in a region of the touch screen 151 close to the first conductive pattern 211. For example, when the shape of an area in which the capacitance is greater than or equal to the reference value Cr among the entire area of the touch screen 151 is compared with a predetermined shape to match each other, the display device 100 displays the touch screen 151 151 in a state in which they are adhered to each other.
On the other hand, in a state where the input device 200 is adhered to the touch screen 151, at least a part of the ball-shaped movable contact 220 is spaced a predetermined distance from the touch screen 151, (Not shown). In this case, the distribution curve of the capacitance induced by the second conductive pattern 222a formed on the moving contact portion 220 is located between the distribution curves of the capacitance induced by the first conductive pattern 211, A constant shape can be maintained.
10 (b) illustrates a state in which the moving contact portion 220 of the input device 200 is rotated counterclockwise by the user.
As the movable contact portion 220 rotates counterclockwise, the electrostatic capacity distribution curve corresponding to the second electroconductive pattern 222a moves to the right, and the electrostatic capacity distribution curve corresponding to the other second electroconductive pattern 222b It can be newly detected. Although not shown, when the movable contact 220 further rotates counterclockwise, the electrostatic capacity distribution curve corresponding to the second conductive pattern 222a is no longer detected by the display device 100, It is apparent to those skilled in the art that the capacitance distribution curve corresponding to the second conductive pattern 222b moves to the right and a capacitance distribution curve corresponding to another second conductive pattern 222c can be newly detected.
The display device 100 has a capacitance corresponding to the continuously changing second conductive patterns 222a, 222b, and 222c in accordance with the rotation of the moving contact portion 220, as described above with reference to FIG. 10 (b) The rotation characteristics including the rotation direction, the rotation speed, the rotation amount, and the like of the moving contact portion 220 can be determined. In addition, the display device 100 may change the state of the screen displayed on the touch screen 151 (e.g., scroll, switch the output screen) or perform a predetermined operation (e.g., drive a specific application) .
11 is a flow chart of an exemplary process S1100 executed by the display device 100 according to an embodiment of the present invention.
In step S1110, the display device 100 may receive a touch signal for one area of the touch screen 151. [ Specifically, the controller 180 may receive a touch input by a target object in proximity to or in contact with the touch screen 151, based on the touch signal provided from the touch screen 151. [ For example, when the input device 200 including the first conductive pattern 211 as shown in FIG. 4 (b) is bonded to the touch screen 151, the controller 180 controls the first conductive pattern 211 by the first conductive pattern 211 It is possible to detect the change in induced capacitance and to determine the shape and / or size of the area that is touched (i.e., proximity or contact) by the first conductive pattern 211, based on the sensed capacitance.
In step S1120, the display device 100 can determine whether the shape of the touched area in the entire area of the display matches the pre-stored shape. For example, the memory 170 may be pre-stored with information on the shape and size of the input device 200 corresponding to the first conductive pattern 211, The shape can be compared with the shape corresponding to the first conductive pattern 211 previously stored in the memory 170 to judge whether the two match each other. In this case, the controller 180 further determines, based on the result of comparing the size of the touch area with the size corresponding to the first conductive pattern 211 previously stored in the memory 170, It can be determined whether or not it matches the pattern 211.
In step S1130, the display device 100 can enter the external input mode. The external input mode in the present invention is a mode in which the screen state of the touch screen 151 is changed or a predetermined operation is performed based on the touch input by the input device 200 and the wireless signal transmitted from the input device 200 Quot; mode "
In step S1140, when the external input mode is entered, the display device 100 may generate a virtual touch area in an area corresponding to a portion of the entire area of the touch screen 151 to which the input device 200 is adhered. The virtual touch area may be an area having a predetermined shape and size so as to receive a touch input from the input device 200. [ For example, the display device 100 can create a virtual touch area inside the area where the first conductive pattern 211 is detected. In this case, the controller 180 may deactivate the touch area of the entire touch area of the touch screen 151 except for the virtual touch area. That is, it may not respond to the touch input to the touch region except for the virtual touch region among the entire touch regions of the touch screen 151. [
In addition, the display device 100 can generate a virtual touch area and output a pointer to the touch screen 151. [ For example, the pointer can be displayed in an area other than the virtual touch area, and the position can be changed in the display area of the touch screen 151 according to the operation of the input device 200. [
In addition, when the communication module 260 is provided in the input device 200, the display device 100 can form a wireless communication network with the communication module 260 together with the generation of the virtual touch area.
In step S1150, the display device 100 may determine whether or not a touch input to the virtual touch area is received. For example, when the capacitance of at least one point of the virtual touch region is equal to or greater than the reference value (Cr) by the moving contact portion 220, the display apparatus 100 may be configured such that the touch input to the virtual touch region is received It can be judged. If the touch input to the virtual touch area is received, the display device 100 may perform step S1160.
In step S1160, the display device 100 can change the state of the screen being output from the touch screen 151 based on the touch input sensed in the virtual touch area. 6 (b), when the moving contact portion 220 moves to the left by more than the reference speed, the control unit 180 displays the screen currently being output on the touch screen 151 as the previous screen . ≪ / RTI > The control unit 180 controls the touch screen 151 to display a screen that is currently being output on the touch screen 151 by a length corresponding to the distance of the moving contact unit 220 moved up and down You can scroll. As another example, when the pointer is output when entering the external input mode as described above, the controller 180 may move the pointer corresponding to the direction and distance in which the moving contact unit 220 moves or rotates.
In step S1170, the display device 100 may determine whether a pressure signal has been received from the input device 200. [ The input device 200 may transmit a pressure signal corresponding to the pressure in the vertical direction applied to the moving contact 220 to the display device 100 via the communication module 260, May receive the pressure signal transmitted from the input device 200 through the communication unit 110. If a pressure signal is received, the display device 100 may perform step S1180. That is, until the pressure signal is received from the input device 200, the display device 100 can repeat steps S1150 and S1160.
In step S1180, the display device 100 can perform an operation corresponding to the received pressure signal. At this time, the display device 100 can sequentially execute a plurality of operations associated with each other depending on the magnitude of the pressure corresponding to the pressure signal or the duration time. For example, assume that the displayed pointer is positioned over a specific icon as the external input mode is entered. In this case, when the pressure of the first size is detected by the pressure sensor 250, the controller 180 stores summary information (e.g., installation date, file size, storage location, etc.) It can be displayed adjacent to the icon. If the pressure of the second size larger than the first size is released within the first time after being detected by the pressure sensor 250, the control unit 180 displays the execution screen of the application corresponding to the specific icon on the touch screen 151). On the other hand, when the pressure of the second magnitude larger than the first magnitude is detected by the pressure sensor 250 and continues for the first time or longer, the controller 180 determines whether to cancel the application corresponding to the specific icon An indicator may be displayed adjacent to the specific icon.
12 shows an example of using the input device 200 according to an embodiment of the present invention.
12, when the input device 200 is bonded to one area of the touch screen 151, the control unit 180 controls the attachment region 1200 having a shape and an area corresponding to the first conductive pattern 211, Can be detected. The attachment area 1200 may be an area indicating the touched area of step S1110 described above with reference to Fig.
The control unit 180 compares the shape and size of the attachment region 1200 with the shape and size previously stored in the memory 170, and if they coincide with each other, the control unit 180 can enter the external input mode.
In the external input mode, the display device 100 can create a virtual touch region 1210 in the attachment region 1200. [ In this case, the controller 180 may change the screen state or perform a predetermined operation in response to only the touch input to the virtual touch area 1210 of the touch screen 151, and ignore the touch input to the remaining area.
The display device 100 may output the pointer 1220 to one area of the touch screen 151 with or without generating the virtual touch area 1210 when the external input mode is entered.
For example, when the home screen on which the icon lists are displayed on the touch screen 151 is displayed, when the user enters the external input mode, the pointer 1220 displays an indicator 1220a displayed on the border of a specific icon, Or may be a finger or an arrow-shaped indicator 1220b as shown in FIG. 12 (b).
When the user moves or rotates the moving contact portion 220 of the input device 200, a capacitance change of the virtual touch region 1210 is generated by the second conductive pattern formed on the moving contact portion 220, and the control portion 180 May adjust the position of the pointer 1220 in the display area of the touch screen 151 based on the capacitance change of the virtual touch area 1210. [
12A and 12B, the virtual touch region 1210 is shown as being circular, but this is merely exemplary and is not intended to limit the scope of the present invention.
FIG. 13 shows an example of using the input device 200 according to an embodiment of the present invention.
The display device 100 can perform a predetermined operation in response to the pressure signal transmitted from the input device 200. [ For example, when a pressure signal corresponding to a predetermined-sized pressure is transmitted from the input device 200, with the pointer 1220 pointing to the Internet icon as shown in Figs. 12A and 12B, the controller 180 Can display an Internet connection screen as shown in FIG. 13 (a) on the touch screen 151 by executing an Internet application which is an application of an icon indicated by the pointer 1220a.
13A, the display device 100 displays the virtual touch area 1210 by the moving contact part 220 of the input device 200 while the arbitrary screen is displayed on the touch screen 151 In response to the touch input, the state of the currently displayed screen can be changed.
For example, when the moving contact portion 220 of the input device 200 moves downward while the Internet connection screen is displayed as shown in FIG. 13A, when the electrostatic capacity in the virtual touch region 1210 is the maximum The point can also move downward corresponding to the moving distance of the moving contact portion 220. [ In this case, the control unit 180 can perform downward scroll operation on the Internet connection screen as shown in FIG. 13 (b). Accordingly, a portion that is not output in Fig. 13A can be outputted to the touch screen 151 in accordance with scrolling.
On the other hand, although not shown, various other operations are possible. For example, when the moving contact unit 220 as shown in FIG. 4 and so on of the input device 200 moves left and right, the control unit 180 can switch the current screen to the previous screen or the next screen. As another example, when the movable contact 220 as shown in Fig. 9 rotates clockwise or counterclockwise with respect to the y-axis, the controller 180 may decrease or increase the volume of the display device 100. [ As another example, when the moving contact 220 as shown in Fig. 9 rotates clockwise or counterclockwise with respect to the x-axis, the screen brightness of the display device 100 may decrease or increase. As another example, when the movable contact 220 as shown in Fig. 9 rotates clockwise or counterclockwise with respect to the z-axis, the screen brightness of the display device 100 may decrease or increase. As another example, when the moving contact portion 220 as shown in Fig. 4 or 9 or the like has elapsed a predetermined time or longer in a state in which the movement or rotation is stopped (i.e., the state is not operated by the user), the display device 100 ) Can display a predetermined screen (e.g., a home screen or a navigation screen) on the touch screen 151. [ As another example, when the moving contact 220 as shown in FIG. 4 or 9 or the like moves or rotates beyond a predetermined speed, the display device 100 may be stored in the memory 170 or stored in a nearby mobile terminal The contact list can be displayed on one side of the touch screen 151. As another example, when the moving contact portion 220 as shown in FIG. 4 or 9, repeats movement or rotation more than a predetermined number of times in different directions within a time limit, the display device 100 touches a preset menu list And can be displayed on one side of the screen 151. On the other hand, in the above-described embodiments, it should be understood that the operations performed in accordance with the movement or rotation of the moving contact 220 are mutually exchangeable.
11 to 13 illustrate embodiments in which one input device 200 is used in the touch screen 151, it should be understood that two or more input devices 200 may be used at the same time. 4 is adhered to the lower left end of the touch screen 151 and the input device 200 of the type shown in Fig. 9 is adhered to the lower right end of the touch screen 151, the display device 100 can simultaneously recognize the area where the two input devices 200 are bonded and change the screen configuration corresponding to the recognized area. For example, when the display device 100 is provided in the center fascia of the vehicle 10 as shown in FIG. 2, when the two input devices 200 are attached to the touch screen 151, It is possible to operate the motor 151.
At least one of the embodiments of the operation of the display device 100 and / or the input device 200 related to the present invention described above can be implemented as a computer-readable code on a medium on which the program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). The computer may also include a controller 180 of the display device. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
