For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, c can be single or multiple.

[0033] The prefixes such as "first" and "second" used in the embodiments of the present application are only used to distinguish different description objects, and have no limiting effect on the position, order, priority, quantity or content of the described objects. The use of prefixes such as ordinal numbers used to distinguish description objects in the embodiments of the present application does not constitute a limitation on the described objects. For the statement of the described objects, please refer to the description in the context of the claims or embodiments, and the use of such prefixes should not constitute an unnecessary limitation.

[0034] In order to better understand the technical solution in this application, the terms involved in this application are first introduced.

[0035] (1) Drive electrode line (Tx): It is a wire in the panel that is specifically used to send electrical signals. It is usually used for line scanning of capacitive touch screens. It generates an electric field by sending pulse signals to the drive electrode line, and cooperates with the sensing electrode line to detect the touch position. Specifically, the Tx signal generates an electric field by sending a low-voltage electric pulse. When a finger touches the screen, it can cause an electric field change between the Tx and Rx electrodes (because the finger is conductive), resulting in a change in capacitance. The screen driver chip detects this change and interprets it as the precise position and action of the touch through the corresponding algorithm.

[0036] (2) Sensing electrode line (Rx): It is a wire in the panel specifically used to receive electrical signals, usually used for column scanning of capacitive touch screens.

[0037] (3) Edge metal wire (trace): It can refer to the wire used to connect various electronic components on the printed circuit board. In the touch panel, the trace line can be used to connect the driver chip and components such as Tx and Rx lines, so that the signal can be transmitted between the touch panel and the driver chip.

[0038] (4) Touch reporting rate: This refers to the number of times the screen detects changes in the touch position per second. It indicates the number of touch points that the touch screen can sample in one second, usually in Hertz (Hz). For example, a touch reporting rate of 120 Hz means that the screen can detect 120 touch operations per second.

[0039] (5) Touch cell (pattern): It is the basic sensing structure in the touch panel and is used to detect the touch position. It consists of a specific arrangement of Tx lines and Rx lines, and each intersection constitutes a touch sensing area. By sensing the change in capacitance during touch, the touch cell can accurately detect information such as the location and pressure of the touch point.

[0040] (6) Self-capacitive electrode solution: This means that each electrode works independently and detects capacitance changes separately. Each electrode will generate an independent capacitance signal due to the contact of the finger when touched.

[0041] (7) Mutual capacitance electrode solution: The mutual capacitance solution relies on the capacitive coupling between the Tx and Rx electrodes. During touch operation, when the finger approaches the electrode grid, the coupling capacitance between the Tx and Rx electrodes is changed, thereby detecting the touch position.

[0042] The technical solution in this application will be described below in conjunction with the accompanying drawings.

[0043] In recent years, the global AMOLED industry has flourished thanks to the excellent color performance, contrast and power consumption of AMOLED displays. AMOLED display technology is not only far superior to traditional LCDs in terms of picture quality, but also provides the possibility of full-screen design and innovative appearance due to the characteristics of its flexible substrate. The plasticity of this flexible substrate allows the screen to be used not only for larger full-screen designs, but also supports a variety of forms such as foldable and curved, further promoting the innovation of terminal devices.

[0044] With the development of technology, the refresh rate of AMOLED screens has gradually increased, making the screen display smoother, especially in video playback, game applications and high frame rate scenes, bringing a better visual experience. However, in the face of the demand for high-end gaming phones, new requirements have been put forward for the screen response speed and touch feedback accuracy, requiring not only a higher refresh rate, but also a higher human-computer interaction frequency to ensure that users get sensitive touch feedback and fast response during the game.

[0045] Although increasing the refresh rate of the entire screen can meet the above requirements, increasing the refresh rate of the entire screen will significantly increase the power consumption of the panel, which is not conducive to the battery life of the device. Therefore, the industry has gradually shifted its research and development focus to local refresh rate technology, that is, to increase the reporting rate in the screen area where user interaction is concentrated, thereby optimizing the interactive experience without increasing overall power consumption.

[0046] For example, Figure 1 As shown, when a user uses a mobile phone to play a game, the second edge area 105 in the middle of the mobile phone screen is the area where the game screen is normally displayed, usually showing the perspective of the game character and the game scene content. Therefore, this area has a lower requirement for touch response speed. The main operation areas of the user are concentrated in the first edge areas 104 on the left and right sides of the screen. These areas are often the areas where the user's fingers touch, and are used to perform high-frequency operations such as character movement, shooting, and skill release. Therefore, improving the touch reporting rate of the first edge areas 104 on the left and right sides of the mobile phone screen is particularly critical to the gaming experience.

[0047] The embodiments of the present application provide a display panel, a driving method and a terminal device, which can improve the touch reporting rate of a certain area in the display panel screen, ensure that every touch of the user can be quickly and accurately fed back to the game, thereby bringing the user a smoother and real-time sense of control.

[0048] In one embodiment, a display panel is provided, which includes: a driving chip, a touch screen and a touch capacitor, the touch screen includes M driving electrode lines and M sensing electrode lines, and the touch capacitor is arranged at the intersection of the M driving electrode lines and the M sensing electrode lines; the driving chip provides N pulse signals to the M driving electrode lines, and senses the output signal of the touch capacitor through the M sensing electrode lines, the N pulse signals are pulse signals provided within one driving cycle, and N is a positive integer greater than M; wherein the M driving electrode lines include X first driving electrode lines 101, Q pulse signals out of the N pulse signals are transmitted through the X first driving electrode lines 101, Q is less than N, and X is less than or equal to half of Q.

[0049] Optionally, the touch capacitor can be a capacitive sensing node, which can generate an initial reference capacitance value. When a finger or a conductive object touches the touch screen, the capacitance value of the touch capacitor can be changed. The touch capacitor can output a signal based on this change, which can be detected and analyzed by the driver chip to determine the touch position and other related information.

[0050] In a possible implementation, the display panel includes an edge metal line 102, each of the X first driving electrode lines 101 is connected to the driving chip through at least two edge metal lines 102, and the edge metal line 102 is used to transmit the pulse signal to the first driving electrode line 101. Through such a design, overlapping interference between pulse signals can be effectively avoided, thereby improving the transmission quality of the pulse signal.

[0051] Optionally, the touch screen includes a first edge region 104 , and the X first driving electrode lines 101 are located in the first edge region 104 .

[0052] Optionally, the touch screen further includes a second edge region 105, the M driving electrode lines include Y second driving electrode lines 103, the Y second driving electrode lines 103 are located in the second edge region 105, and each of the Y second driving electrode lines 103 transmits a pulse signal. Further optionally, X+Y=M.

[0053] In a possible implementation, the X first driving electrode lines 101 are adjacent driving electrode lines among the M driving electrode lines.

[0054] For example, Figure 2 As shown, the display screen in the display panel includes 13 driving electrode lines, including 8 first driving electrode lines 101 and 5 second driving electrode lines 103. Each of the 8 first driving electrode lines 101 transmits 2 pulse signals (respectively, pulse signals sent at time T1 to T8 and T14 to T21), and each of the 5 second driving electrode lines 103 transmits one pulse signal (respectively, pulse signals sent at time T9 to T13). The driving chip can send 21 pulse signals in sequence in the time sequence of T1 to T21 within one driving cycle; Figure 2 In the example shown, M=13, N=21, X=8, Y=5, and Q=16.

[0055] like Figure 3 As shown in FIG. 1 , since the generated pulses of adjacent pulse signals may partially overlap, Figure 2 In the embodiment, each of the eight first driving electrode lines 101 can be connected to two edge metal lines 102, and each edge metal line 102 transmits a pulse signal. In this way, the driving chip transmits two Tx signals through two edge metal lines 102, which can effectively avoid overlapping interference between Tx signals and meet the requirement of improving the reporting rate of the first driving electrode line 101 in the first edge area 104.

[0056] In practical applications, the output lines of Tx and Rx can be, for example, Figure 4 As shown, the 2TR1 output line method or the 2T2R output line method can be used to reduce the attenuation of the signal in the middle area of ​​the display panel.

[0057] In the embodiment of the present application, since Q pulse signals among the N pulse signals are transmitted through X first driving electrode lines, and X is less than or equal to 2 / Q, the X first driving electrode lines are arranged in the first edge area of ​​the touch screen, which can improve the touch reporting rate of the first edge area in the display panel touch screen, ensuring that every touch of the user can be quickly and accurately fed back to the game, thereby bringing the user a smoother and real-time sense of control.

[0058] In one embodiment, a driving method is provided, which is applied to a driving chip, wherein the driving chip is connected to M driving electrode lines through i edge metal lines, i is a positive integer greater than M, the M driving electrode lines include X first driving electrode lines 101, each of the X first driving electrode lines 101 is connected to the driving chip through at least two edge metal lines 102, the i edge metal lines include a first edge metal line and a second edge metal line, the first edge metal line and the second edge metal line are connected to a third driving electrode line, the third driving electrode line is any first driving electrode line among the X first driving electrode lines, X is a positive integer less than M, and the driving method includes: sending a first pulse signal to the third driving electrode line through the first edge metal line at a first moment, and sending a second pulse signal to the third driving electrode line through the second edge metal line at a second moment, the first moment and the second moment are in the same driving cycle, and the difference between the second moment and the first moment is greater than the duration of the first pulse signal.

[0059] For example, Figure 2 As shown, the driving chip is connected to 13 driving electrode lines through 21 edge metal lines, the 13 driving electrode lines include 8 first driving electrode lines 101 and 5 second driving electrode lines 103, and each of the 8 first driving electrode lines is connected to the driving chip through 2 edge metal lines. Then in the driving method, the third driving electrode line can be the first first driving electrode line arranged from top to bottom in the display screen, the first moment can be T1, the first pulse signal is the pulse signal sent at T1, the second moment can be T5, the second pulse signal is the pulse signal sent at T5, and the difference between the second moment and the first moment can be greater than Figure 3 The duration of the pulse signal (ie, touch pulse) sent at time T1 shown in FIG.

[0060] It should be noted that the above-mentioned first moment and second moment being T1 and T5 respectively are merely exemplary descriptions, and the present application does not limit the first moment and the second moment. For example, the first moment and the second moment may also be T17 and T21 respectively, and the third driving electrode line may be the last first driving electrode line arranged from top to bottom in the display screen.

[0061] In an embodiment of the present application, the difference between the second moment when the driving chip sends the second pulse signal and the first moment when the driving chip sends the first pulse signal is greater than the duration of the first pulse signal. In this way, the first pulse signal and the second pulse signal can be prevented from overlapping in driving time, thereby effectively avoiding interference between the pulse signals.

[0062] In one embodiment, a driving chip is provided. The driving chip includes a circuit for executing the above driving method.

[0063] In one embodiment, a display panel is provided, which includes: a touch screen, which includes a first edge area 104 and a second edge area 105, the first edge area 104 includes a plurality of first touch units 106, the second edge area 105 includes a plurality of second touch units 107, and the area of ​​the second touch unit 107 is N times the area of ​​the first touch unit 106, where N is greater than or equal to 2.

[0064] Optionally, the plurality of first touch control units 106 are arranged in an array, and the plurality of second touch control units 107 are arranged in an array.

[0065] Optionally, the first edge area 104 may also be referred to as a game operation area, and the second edge area 105 may also be referred to as a non-game operation area.

[0066] Optionally, the first edge region 104 and the second edge region 105 may be in any shape, for example, a triangle, a rectangle, a square, or a circle.

[0067] For example, Figure 5 As shown, the green part represents the touch unit, and the white and black parts represent the non-touch unit. Figure 5 In the embodiment, the touch control unit in the corner area (corresponding to the first edge area 104) is changed, the Tx signal is divided into two independent signal channels, and the number of channels of the Rx signal is doubled accordingly. Thus, a plurality of first touch control units 106 can be formed in the corner area, while the display area (corresponding to the second edge area 105) is not changed, that is, the display area includes a plurality of second touch control units 107, and the area of ​​the second touch control unit 107 is twice the area of ​​the first touch control unit 106.

[0068] For example, Figure 6 As shown, the green part represents the touch unit, and the white part represents the non-touch unit. Figure 6 In the embodiment, the touch control units in the left and right areas (corresponding to the first edge area 104) of the touch screen are changed, the Tx signal is divided into two independent signal channels, and the number of channels of the Rx signal is doubled accordingly. Thus, the left and right areas can form a plurality of first touch control units 106 arranged in an array, while the middle area (corresponding to the second touch control area and the second edge area 105) is not changed, that is, the display area includes a plurality of second touch control units 107 arranged in an array, and the area of ​​the second touch control unit 107 is twice the area of ​​the first touch control unit 106.

[0069] In the embodiment of the present application, by setting the area ratio of the touch unit in the first edge area and the second edge area, the touch reporting rate of the first edge area can be improved. When the user operates the character in the game through the first edge area, it can ensure that every touch of the user can be quickly and accurately fed back to the game, thereby bringing the user a smoother and real-time sense of control.

[0070] In one embodiment, a display panel is provided, which includes: a driving chip, a touch screen, a self-capacitive electrode 108 and a touch capacitor, the touch screen includes: a first edge area 104 and a second edge area 105, the first edge area 104 includes P edge metal lines 102, the driving chip is connected to the P self-capacitive electrodes 108 through the P edge metal lines 102, the second edge area 105 includes M driving electrode lines and M sensing electrode lines, the touch capacitor is arranged at the intersection of the M driving electrode lines and the M sensing electrode lines, P and M are positive integers; the driving chip sends P pulse signals to the P edge metal lines 102, and senses the output signals of the P self-capacitive electrodes 108 through the P edge metal lines 102, and the driving chip sends M pulse signals to the M driving electrode lines, and senses the output signals of the touch capacitor through the M sensing electrode lines.

[0071] The wiring method of the first edge region 104 may also be referred to as a self-capacitive electrode solution, and the wiring method of the second edge region 105 may also be referred to as a mutual-capacitive electrode solution.

[0072] Optionally, the first edge area 104 may also be referred to as a game operation area, and the second edge area 105 may also be referred to as a non-game operation area.

[0073] For example, Figure 7 As shown, in the conventional wiring method, the sensing electrode lines are arranged less on one side of the touch screen in the length direction, and more on the other side of the touch screen in the length direction (corresponding to Figure 7 In the example, the left side of the touch screen has fewer lines, and the right side of the touch screen has more lines). Therefore, the lines of the self-capacitive electrode solution can be introduced on the side with fewer lines of the touch screen. For example, the wiring solution of the first edge area 104 can be as follows: Figure 8 and Fig. 9 As shown, in Figure 8 and Fig. 9 The high-frequency operation area may correspond to the first edge area 104 . In the high-frequency operation area, the driver chip may be connected to the P self-capacitive electrodes 108 via P edge metal wires 102 , and the lengths of the edge metal wires 102 may be the same or different.

[0074] In the embodiment of the present application, a self-capacitive electrode solution is used in the first edge area, and a mutual-capacitive electrode solution is used in the second edge area, which can improve the touch reporting rate of the first edge area in the display panel touch screen, ensuring that every touch of the user can be quickly and accurately fed back to the game, thereby providing the user with a smoother and real-time sense of control. On the other hand, it is conducive to reducing the power consumption of the panel, thereby improving the battery life of the display panel.
