As shown in FIG. 4, the display device according to an embodiment of the present invention may display the game content 400 on the display unit 151. FIG.

In addition, when providing the touch panel, the display device may display the touch interface 412 or 414 for the game user to play the game in a specific area of the display unit 151. [

The game user can transmit a plurality of inputs required for the game to the device using the touch interface 412 and 414.

In general, the touch interfaces 412 and 414 may be displayed on the display unit 151 according to the sizes and positions preset by the game contents provider.

For example, the first touch interface 412 may be displayed on the lower left side of the display unit 151, and the second touch interface 414 may be displayed on the lower right side of the display unit 151.

On the other hand, even if a game user plays a game with the same device, a touch input error phenomenon may appear to some game users according to different hand sizes.

For example, even if the user touches the first touch interface 412 to touch the first touch error point 422 or touches the second touch interface 414 to touch the second touch error point 424, A touch input error phenomenon such as touching the touch panel may occur.

Further, since the positions of the touch error points are different for each game user, changing the touch interface display position can not be set uniformly.

5 is a view for explaining a touch interface adjusting method provided in a display device according to an embodiment of the present invention.

In order to solve the problem occurring in FIG. 4, the display device of the present invention for providing game contents can provide the game users with the function of adjusting the touch interface.

That is, as described with reference to FIG. 4, the touch input error phenomenon occurrence data is collected and the position and size of the touch interface can be adjusted to correspond to the touch point of the user who uses the game through the device based on the collected data.

For example, the display device can adjust (510) the position of the touch interface or adjust the size of the touch interface (520).

If the position or size of the touch interface is changed, even if the game user inputs the same input as usual, the touch input error phenomenon does not occur and the convenience of the game progress can be increased.

6 and 9 are diagrams for explaining a touch interface adjusting method provided in a display device according to an embodiment of the present invention.

As shown in FIG. 6, the display device may add a separate game process for adjusting the touch interface.

For example, when the game user directly selects the position or size of the touch interface, the display device can display the selected touch interface on the display unit.

In addition, the game content provider may add a separate tutorial for adjusting the touch interface, and collect and analyze certain tutorial play data of the user, thereby providing a game user with a touch interface having an optimized size and position.

Then, the display device continuously collects and analyzes the game data of the game user, thereby finely adjusting the position and size of the touch interface.

Therefore, the game user can expect a technical effect that the touch input error phenomenon decreases as the game progresses.

Furthermore, the display device can store the game user's touch interface data for each game type.

Therefore, in case of playing another game of the same type, a technical effect that can promptly provide a game interface with a touch interface having a position and size optimized for a game user based on the corresponding game interface type touch interface data .

Accordingly, a game user can be provided with an optimized touch interface without having to go through a setup process or a tutorial when proceeding with a new game. As a result, there is a feature that touch error phenomenon can be minimized.

11 is a view for explaining a configuration module of a display device according to another embodiment of the present invention.

11, a display device 1100 according to another embodiment of the present invention may include an interface unit 1140, a touch screen 1130, a storage unit 1120, and a control unit 1110. Referring to FIG. The touch screen 1130 may include a display unit 1131, a touch panel 1132, and a touch controller 1133.

The interface unit 1140 is an apparatus to which an external device such as an earphone, a charger, a universal serial bus (USB) cable, or an accessory is connected. Hereinafter, the external device will be collectively described. The interface unit 1140 is formed of a metal material. The interface unit 1140 may transmit an interrupt signal to the control unit 1110 when the external device is inserted.

The touch screen 1130 may perform a touch input function and a screen output function. For this, the touch screen 1130 may include a display unit 1131, a touch panel 1132, and a touch controller 1133.

The display unit 1131 displays various menus of the display device 1100, and displays information inputted by the user or information to be provided to the user. For example, the display unit 1131 can provide various screens such as a standby screen, a message creation screen, a call screen, and the like according to the use of the display device 1100. The display unit 1131 may be a liquid crystal display, an OLED (Organic Light Emitting Diode), or an AMOLED (Active Matrix Organic Light Emitting Diode).

The touch panel 1132 is mounted on the front surface of the display unit 1131. When a touch event occurs, a physical quantity (e.g., electrostatic capacity) corresponding to the touch event is changed. The touch panel 1132 can transmit a change in physical quantity according to a touch to the touch controller 1133.

The touch controller 1133 transmits to the control unit 1110 a message type variable such as X, Y channel, number of channels, release time, vector value for touch movement, and size of the touch area for coordinate recognition . The touch controller 1133 can communicate with the controller 1110 through the I 2 C scheme. The touch controller 1133 may include a touch acquisition process for determining whether a touch is generated, a message process for transmitting information such as X and Y coordinates to a control unit 1110 in a read data format, Touch process, a reset command, a test mode entry command, and a power-up command to determine a vector value, a touch area, a number of valid taps, a touch release time, A command process for performing a command, a recalibration command, and the like, and a grip area process for setting a grip area 1135 in the outer area of the entire touch area. The grip area 1135 may be generally located outside the touch screen 1130 when the user touches the display device 1100. Each process may be assigned an ID (identification). The process ID is transmitted together with the message transmission. Each process ID is stored in a table in which information such as an address and a size of the process is stored.

The storage unit 1120 may store user data and the like as well as programs necessary for the functional operation according to the embodiment of the present invention. For example, the storage unit 1120 may include a program for controlling the overall operation of the display device 1100, an operating system (OS) for booting the display device 1100, ) Function, for example, a camera function, a sound reproducing function, an image or moving picture reproducing function, an application program necessary for a short-range wireless communication function, and the like. The storage unit 1120 may store user data, such as a text message, a game file, a music file, and a movie file, which are generated according to the use of the display device 1100. In particular, the storage unit 1120 according to the present invention may store a program for preventing insertion of an external device (e.g., an accessory) or a touch malfunction caused by a user's grasp.

The controller 1110 may control the overall operation of the display device 1100 and the signal flow between the internal blocks of the display device 1100. In particular, when the insertion of the external device is detected, the control unit 1110 according to the present invention can transmit a command to the touch controller 1133 to recalculate a reference value for touch recognition. In detail, the controller 1110 can transmit the rebalance command to the command process of the touch controller 1133 through I2C communication. At this time, the controller 1110 may ignore the touch input until receiving a readjustment completion message from the touch controller 1133 from the time the external device is inserted. The control unit 1110 may transmit a reference value readjustment command to the touch control 1133 when an external device is disconnected. This is to restore the changed reference value to the original state by inserting the external device.

Also, the controller 1110 can prevent a touch malfunction caused by a user's grip when a touch is generated. In detail, the controller 1110 may confirm whether the touch is an unintended touch, and may transmit a readjustment command to the touch controller 1133 to readjust the reference value for touch recognition when it is determined that the touch is unintended. For this, the controller 1110 checks whether a touch occurs in the predetermined grip area 1135 when a touch is generated, and can check the touch area when a touch occurs in the grip area 1135. [ That is, if the touch area is large, the controller 1110 can determine the user's grip. The controller 1110 may determine that the touch is caused by the user's finger when the number of touch channels or the number of coordinates transmitted due to the touch exceeds a preset threshold value.

The control unit 1110 can transmit a readjustment command of the reference value to the touch controller 1133 when the touch by gripping is released. This is because a normal touch can not be recognized when the readjusted reference value is maintained in the grip releasing state. As described above, the present invention can prevent touch malfunction by re-adjusting the reference value appropriately according to the situation.

In the above description, the controller 1110 performs the touch malfunction prevention procedure due to the user's grasp, but the present invention is not limited thereto. For example, in another example, the touch controller 1133 may perform at least a part of the touch malfunction prevention procedure due to the above-described grasp of the user.

FIG. 12 is a flowchart for schematically explaining a method for preventing a touch malfunction of a display device by a game user's grip according to an embodiment of the present invention.

Referring to FIG. 12, the controller 1110 according to an embodiment of the present invention can detect touch generation in step 1201. FIG. In step 1203, the controller 1110 can confirm whether the sensed touch is an unintentional touch due to a user's grip. A method of confirming whether the touch is unintentional due to the grip can use a touch area, a touch pressure, the number of channels of a touched point, and the like. A detailed description thereof will be given later. If the touch is not due to the grip, the controller 1110 can perform the corresponding function in step 1205. [ For example, the control unit 1110 may perform a function assigned to the touched icon. On the other hand, if the touch is due to the finger, the controller 1110 can readjust the reference value for touch recognition in step 1207. [

The controller 1110 can confirm whether the grip is released in step 1209. [ The controller 1110 can maintain the step 1209. [0086] On the other hand, if the grip is released, the controller 1110 can readjust the reference value in step 1211. [

Although not shown in FIG. 12, the present invention may further include determining whether the touch occurs in the grip area when the touch is detected. If a touch is not generated in the grip area, the controller 1110 controls to perform a function assigned to the touched area similarly to the conventional method. If a touch occurs in the grip area, the controller 1110 controls the touch panel 1203 Step can be performed.

In addition, the present invention may further include checking whether a touch occurs in an active area when a touch is detected. Here, the active area is an area where an icon is displayed, and the area mapped at the time of touching is performed. If the touch is not generated in the active area, the controller 1110 controls to perform the re-adjustment, and may perform a process of checking if the touch occurs in the grip area when the touch occurs in the active area . If a touch is not generated in the grip area, the controller 1110 controls to perform a function assigned to the touched area similarly to the conventional method. If a touch occurs in the grip area, It can be controlled to perform step 1203.

13 is a flowchart for explaining a first embodiment of a method for preventing a touch malfunction of a display device by a game user grip.

13, in step 1301, the touch panel 1132 can transmit a touch generated by the user's touch to the touch controller 1133. [ The touch generation can be recognized through a change in physical quantity (e.g., capacitance). The touch controller 1133 can transmit a message corresponding to the touch generation (hereinafter referred to as a touch message) to the controller 1110 in step 1303.

Specifically, the touch controller 1133 generates an interrupt for transmitting a message to the controller 1110, and can release the interrupt after transmitting the touch message. At this time, the controller 1110 and the touch controller 1133 can perform an error checking procedure. The error checking procedure may use a checksum method. Since the error checking procedure is a known technique, a detailed description thereof will be omitted.

In step 1305, the controller 1110 receiving the touch message analyzes the touch message to check whether a touch occurs in the grip area. If there is no touch in the grip area, the controller 1110 may proceed to step 1307 to perform the corresponding function. For example, the controller 1110 may perform a function assigned to the touched area. On the other hand, if a touch is generated in the grip area, the controller 1110 can check whether the touch area exceeds a predetermined first threshold in step 1309. [

If the touch area does not exceed the first threshold, the controller 1110 may proceed to step 1307 to perform the corresponding function. That is, the controller 1110 may perform a function assigned to the touched area by determining that the touch is not a touch by a user's grip but a normal touch. On the other hand, if the touch area exceeds the first threshold, the controller 1110 may transmit a rebalance command to the touch controller 1133 to re-adjust the reference value for touch recognition in step 1311. [ The rebalancing command may be sent with an I2C Write command.

In step 1313, the touch controller 1133 receiving the re-alignment command may perform re-adjustment. When the re-adjustment is completed, the touch controller 1133 can transmit a re-adjustment completion message to the controller 1110 in step 1315. [ In this way, when the user grips a portion of the touch panel 1132 and re-adjusts the reference value, the touch by the user grip does not exceed the set threshold value, so that the touch is not recognized as having occurred. Therefore, the present invention can prevent the touch malfunction caused by the user grip.

If it is determined that the touch by the user's grip is released, the controller 1110 may transmit a reference value readjustment command to the touch controller 1133, though not shown. This is to prevent the problem that the user does not recognize a normal touch input to the area held by the user after releasing the grip when the readjusted reference value is maintained in the grip state.

14 is a flowchart for explaining a second embodiment of a method for preventing a touch malfunction of a display device due to user grasping.

Referring to FIG. 14, in step 1401, the touch panel 1132 can transmit a touch generated by a user's touch to the touch controller 1133. In step 1403, the touch controller 1133 may transmit a touch message to the controller 1110. Specifically, the touch controller 1133 generates an interrupt to transmit the touch message to the controller 1110, and can release the interrupt after transmitting the touch message. At this time, the controller 1110 and the touch controller 1133 can perform an error checking procedure. The error checking procedure may use a checksum method. Since the error checking procedure is a known technique, a detailed description thereof will be omitted.

In step 1405, the controller 1110 receiving the touch message analyzes the touch message to check whether a touch occurs in the grip area. If there is no touch in the grip area, the controller 1110 may proceed to step 1407 to perform the corresponding function. For example, the controller 1110 may perform a function assigned to the touched area. On the other hand, if a touch occurs in the grip area, the controller 1110 can check whether the touch area is less than a predetermined first threshold in step 1409. [ If the touch area is not less than the first threshold value, the controller 1110 may proceed to step 1413, which will be described later. On the other hand, if the touch area is less than or equal to the first threshold value, the controller 1110 proceeds to step 1411 and determines whether the touch pressure exceeds a predetermined second threshold value. The second threshold value may be a hysteresis value. That is, when the capacitance change due to the touch is out of the hysteresis value, the controller 1110 can determine that an excessive pressure has occurred. This is based on the fact that the pressure generated by the grip is larger than the pressure generated by the general touch. For example, the pressure of the touch screen 1130 can be measured by pressing the touch screen 1130 with a finger to increase the touch area. That is, when the electrostatic capacity value changed due to the increase of the touch area after touch sensing exceeds the hysteresis value, the controller 1100 can determine that an excessive pressure has occurred. Alternatively, the touch screen 1130 may include a separate pressure sensing means.

If the touch pressure does not exceed the second threshold, the controller 1110 may proceed to step 1407 to perform the corresponding function. That is, the controller 1110 may perform a function assigned to the touched area by determining that the touch is not a touch by a user's grip but a normal touch. On the other hand, if the touch pressure exceeds the second threshold, the controller 1110 may transmit a rebalance command to the touch controller 1133 to re-adjust the reference value for touch recognition in step 1413. In step 1415, the touch controller 1133 having received the readjustment command may perform readjustment. When the re-adjustment is completed, the touch controller 1133 can transmit a re-adjustment completion message to the controller 1110 in step 1417. [

If it is determined that the touch by the user's grip is released, the controller 1110 may transmit a reference value readjustment command to the touch controller 1133, though not shown.

15 is a block diagram of a display device according to another embodiment of the present invention.

15, the display device includes a touch screen 1510, a capacitance distribution determination unit 1520, a control unit 1530, and a memory 1540.

The touch screen 1510 includes a display 1512 and a touch screen panel 1514. The display 1512 may be a liquid crystal display (LCD), an organic light emitting diode (OLED) panel, or the like.

The touch screen panel 1514 is responsive to a touch and outputs a corresponding touch input signal to the control unit 1530. Specifically, when the user touches the touch screen, the touch screen panel 1514 provides the generated signals as an electric impulse to the capacitance distribution determination unit 1520 and the control unit 1530. Specifically, the touch screen panel 1514 includes a sensor grid configured to intersect a horizontal line and a vertical line, and all the points of the grid generate a unique signal when touched, and are transmitted to a determination unit or a control unit And transmits a unique signal as touch data. This allows the mobile terminal to measure the positions and movements of multiple contacts simultaneously.

The electrostatic capacity distribution diagram determiner 1520 can analyze the touch data and determine characteristics of each touch. The characteristics of the touch include the size of the touch, the shape, and the position touched on the touch screen.

16 is a diagram illustrating an operation of a capacitance distribution diagram determiner according to another embodiment of the present invention.

Referring to FIG. 16, when the touch screen panel 1514 is touched, the capacitance distribution diagram determining unit 1520 receives data as shown in FIG. 16A. The data shown in (a) of FIG. 16 is detected by sensing a current at points of the grid sensing a touch on the touch screen, as described above, and accordingly includes current amount information.

The electrostatic capacity distribution diagram determiner 1520 removes background noise from the touch data of FIG. 16A to generate data as shown in FIG. 16B. Then, the electrostatic capacity distribution diagram determiner 1520 determines the electrostatic capacity distribution diagram by patterning the data shown in Fig. 16B. Specifically, the electrostatic capacity distribution diagram determiner 1520 determines the electrostatic capacity distribution diagram by patterning the received data according to the amount of current detected at each point.

In another embodiment, the amount of current detected at each point can be replaced by the intensity of the pressure at each point. In other words, the electrostatic capacity distribution diagram determiner 1520 may determine the electrostatic capacity distribution diagram by patterning the data representing each touched point according to the pressure intensity detected at each point.

Then, the electrostatic capacity distribution degree determination unit 1520 provides the determined electrostatic capacity distribution diagram to the control unit 1530. [

This electrostatic capacity distribution diagram changes depending on the position of the user's eyes with respect to the display device having the touch screen. When the user's hand touches the touch screen when the display device is located at approximately the same height as the eyes of the user, the user has a capacitance distribution diagram as shown in Fig. 16C.

Also, when the user's hand touches the touch screen when the display device is positioned upward or downward with respect to the eyes of the user, a capacitance distribution diagram as shown in Fig. 17 is shown. Hereinafter, this will be described in detail.

When the display device is positioned upward with respect to the eyes of the user, that is, at a position higher than the eyes of the user, the user's gaze is upward, and the user's finger is further pressed or brought into contact with the upper portion of the touch point . In this case, the amount of current is high or the intensity of pressure is high at the upper portion of the touch point, and accordingly, a capacitance distribution diagram as shown in Figs. 17A and 17C is shown. 17 (a) shows a capacitance distribution diagram when the angle formed by the touch screen and the touch point in the display device is 15 to 35 degrees, FIG. 17 (c) shows the touch screen and the touch point Shows an electrostatic capacity distribution diagram when the angle formed is from 35 degrees to 60 degrees.

When the display device is located downward with respect to the eyes of the user, that is, at a position lower than the eyes of the user, the user's gaze is downward, so that the user's finger touches or touches the lower portion of the touch point more do. In this case, the amount of current is large or the intensity of the pressure is large at the lower portion of the touch point, and accordingly, a capacitance distribution diagram as shown in (b) and (d) of FIG. 17 (b) shows a capacitance distribution diagram when the angle formed by the touch screen and the touch point in the display device is -15 to -35 degrees, FIG. 17 (d) And the angle formed by the point is in the range of -35 degrees to -60 degrees.

The controller 1520 controls the overall operation of the display device. Upon receiving the electrostatic capacity distribution diagram from the electrostatic capacity distribution determining unit 1520, the controller 1520 determines the electrostatic capacity distribution type corresponding to the received electrostatic capacity distribution diagram. Specifically, upon receiving the electrostatic capacity distribution diagram from the electrostatic capacity distribution diagram determiner 1520, the controller 1520 determines which of the types shown in FIG. 18 belongs to the electrostatic capacity distribution diagram.

The electrostatic capacity distribution diagram corresponds to type 1 if it has the form of FIG. 17 (a) and corresponds to type 2 if it has the form of FIG. 17 (c). And corresponds to type 3 when the electrostatic capacity distribution diagram substantially has the form of Fig. 16 (c). The electrostatic capacity distribution diagram corresponds to type 4 if it has the form of Fig. 17 (b) and corresponds to type 5 if it has the form of Fig. 17 (d).

In the memory 1540, a touch angle corresponding to the electrostatic capacity distribution type is stored as shown in FIG.

As described above, the control unit 1520 determines which of the plurality of types the electrostatic capacity distribution diagram belongs to, and reads the type of touch angle to which the electrostatic capacity distribution diagram belongs from the memory 1540.

Specifically, when the electrostatic capacity distribution type is Type 1, it corresponds to the upward 1 type where the angle formed by the touch screen and the touch point is 15 ° to 35 °, and when the electrostatic capacity distribution type is Type 2, Corresponds to two types of upward direction which form 35 degrees to 60 degrees. Also, when the capacitance distribution type is Type 3, it corresponds to a horizontal type in which the angle formed by the touch screen and the touch point is 15 degrees to -15 degrees. If the capacitance distribution type is Type 4, it corresponds to a type 1 downward angle of -15 degrees to -35 degrees formed by the touch screen and the touch point. If the capacitance distribution type is Type 5, the angle formed by the touch screen and the touch point is And corresponds to two downward types of -35 degrees to -60 degrees.

When the controller 1520 reads the touch angle from the memory 1540, the controller 1520 corrects the effective area corresponding to the touch input based on the read touch angle. For example, if the touch angle is 15 degrees to 30 degrees corresponding to the upward direction 1, the effective area according to the touch input is corrected by 4 pixels, and if the touch angle is 35 degrees to 60 degrees corresponding to the upward direction 2, Pixel by 8 pixels.

Specifically, the controller 1520 corrects the effective area on the touch screen according to the user's touch input according to the touch angle. If the touch angle is in the range of 15 degrees to -15 degrees corresponding to the horizontal direction, The area is not corrected.

If the touch angle is 15 degrees or more or -15 degrees or less corresponding to the upward or downward direction, the controller 1520 corrects the effective area determined according to the touch input of the user. If the touch angle is 15 degrees or more, the controller 1520 corrects the effective area determined according to the touch input such that the effective area is shifted upward on the touch screen. If the touch angle is less than -15 degrees, the control unit 1520 corrects the effective area determined according to the touch input such that it shifts downward on the touch screen.

Then, the controller 1520 determines a touch input value according to the effective area. In other words, when the effective area according to the touch input is changed, the controller 1520 determines the touch input value based on the changed effective area.

Hereinafter, a method of correcting the position of the touch point on the touch screen in the display device will be described with reference to FIG.

19 is a flowchart illustrating a method of correcting a position of a touch point on a touch screen according to an embodiment of the present invention.

Referring to FIG. 19, the display device first determines in step 1910 whether there is a touch input by the user. When a user touches the touch screen by using his / her finger, the touch screen generates a unique signal, so that a touch by the user can be detected.

When the touch input is performed by the user, the display device proceeds to step 1920 to determine the capacitance distribution diagram. As described above, when the touch input is performed by the user, the touch data is detected by sensing the current at the points of the grid sensing the touch on the touch screen. The display device determines the electrostatic capacity distribution diagram based on the touch data. The capacitance distribution is determined by patterning data representing each touched point according to the amount of current detected at each point. In another embodiment, the amount of current detected at each point can be replaced by the intensity of the pressure at each point.

Then, the display device determines the capacitance distribution diagram in step 1930, and then reads the touch angle corresponding to the capacitance distribution diagram from the memory. Specifically, when the display device determines the electrostatic capacity distribution diagram, it judges which type among the types shown in Fig. 18 belongs to the electrostatic capacity distribution diagram. The display device determines which type of the electrostatic capacity distribution diagram belongs to which of the plurality of types, and then reads the touch angle of the type to which the electrostatic capacity distribution diagram belongs from the memory.

Subsequently, in step 1940, the display device corrects the effective area according to the touch input based on the read touch angle.

When the touch angle is 15 degrees to 30 degrees corresponding to the upward direction 1, the effective area according to the touch input is corrected by 4 pixels, and when the touch angle is 35 degrees to 60 degrees corresponding to the upward direction 2, Correct the area by 8 pixel points.

Then, the display device determines the touch input value according to the effective area. In other words, when the effective area according to the touch input is changed, the display device determines the touch input value based on the changed effective area.

In order to solve the problem that the effective area depending on the touch is changed by the angle formed between the touch screen and the user in the display device employing the touch user interface, .
