It can be understood that the touch control and display driver integrated chip 200 can also include other structures besides the structures shown in the figure.

[0143] The present disclosure provides a display device 1000. In some embodiments, Figure 1 As shown, the display device 1000 includes a display panel 100. The display panel 100 has a display area AA, and a plurality of pixels are arranged in the display area AA of the display panel 100.

[0144] For example, Figure 1 As shown, each pixel includes at least three color sub-pixels P, and the at least three color sub-pixels P include at least a first color sub-pixel, a second color sub-pixel, and a third color sub-pixel. The first color, the second color, and the third color are three primary colors, such as R (Red), G (Green), and B (Blue).

[0145] Exemplarily, the display device 1000 may be a liquid crystal display (LCD), an electroluminescent display (ELD), a photoluminescent display (PLD), or the like.

[0146] When the display device 1000 is an electroluminescent display device, the electroluminescent display device may be an organic electroluminescent display device (eg, Organic Light-Emitting Display, OLED for short) or a quantum dot light emitting display device (Quantum Dot Light Emitting Display, QLED for short).

[0147] When the display panel 100 is a photoluminescent display screen, the photoluminescent display screen may be a quantum dot photoluminescent display screen.

[0148] The display device 1000 described above may be any device that displays, whether in motion (e.g., video) or fixed (e.g., still image), and whether text or image. More specifically, it is contemplated that the embodiments described may be implemented in or associated with a variety of electronic devices, including but not limited to mobile phones, wireless devices, personal data assistants (PDAs), handheld or portable computers, GPS receivers / navigators, cameras, MP4 video players, video cameras, game consoles, watches, clocks, calculators, television monitors, flat panel displays, computer monitors, automotive displays (e.g., odometer displays, etc.), navigators, cockpit controls and / or displays, displays of camera views (e.g., displays of rear-view cameras in vehicles), electronic photographs, electronic billboards or signs, projectors, architectural structures, packaging, and aesthetic structures (e.g., displays of images of a piece of jewelry), etc.

[0149] The following embodiments of the present disclosure are described by taking the display device 1000 as an electroluminescent display device as an example. In this case, the display panel 100 is an electroluminescent display panel.

[0150] In some embodiments, Figure 2 As shown, the display device 1000 is, for example, a touch display device.

[0151] In some examples, the display device 1000 includes: a display panel 100 and a touch structure 1. The display panel 100 includes a substrate 10. The touch structure 1 is disposed on the substrate 10 and electrically connected to the display panel 100. The touch structure 1 is disposed on the light emitting side of the display panel 100.

[0152] The substrate 10 includes but is not limited to PI (Polyimide Film) or glass.

[0153] In this case, the display panel 100 can realize the display function, and the touch function of the display device 1000 is realized by mounting the touch structure 1 on the display panel 100 .

[0154] In other examples, the display panel 100 includes: a display substrate and a touch structure 1. The touch structure 1 is electrically connected to the display substrate, and the touch structure 1 is arranged on the light-emitting side of the display substrate. The display substrate is configured to implement a display function, and the touch structure 1 is configured to implement a touch function. In this case, the display panel 100 is a touch display panel, and a single display panel 100 can implement display and touch functions.

[0155] The display panel 100 needs to be connected to an external driving structure (such as a display driving chip and a touch driving chip, etc.) to obtain driving signals (such as a display driving signal and a touch driving signal light) to realize the display and touch functions of the display panel 100.

[0156] In some embodiments, the display device 1000 further includes a display driver chip and a touch driver chip. The display driver chip is connected to the data pin 32 of the display panel 100 and is configured to drive the display panel 100 to realize the display function; the touch driver chip is connected to the first touch pin 31 of the display panel 100 and is configured to drive the display panel 100 to realize the touch function. In this case, the display and touch functions of the display device 1000 are controlled by two chips respectively, and the integration of the display device 1000 is low.

[0157] Based on this, an embodiment of the present disclosure provides a touch and display driver integrated chip 200, which has a display driving function and a touch driving function. When the touch and display driver integrated chip 200 is connected to the display panel 100 accordingly, the display panel 100 can be driven to realize touch and display functions through a single touch and display driver integrated chip 200.

[0158] The following description takes the display panel 100 as a touch display panel as an example, and introduces the display panel 100 and the touch and display driver integrated chip 200 respectively.

[0159] In some embodiments, Figure 2 As shown, the display device 1000 includes a display panel 100 and a touch control and display driver integrated chip 200. The display panel 100 is electrically connected to the touch control and display driver integrated chip 200.

[0160] Exemplarily, when a finger touches the display panel 100 , the touch structure 1 generates a touch sensing signal (eg, a first touch signal and a second touch signal) and transmits the signal to the touch and display driver integrated chip 200 .

[0161] Exemplarily, the touch control and display driver integrated chip 200 is configured to provide screen display data (the screen display data includes data voltage signals corresponding to each pixel in the display panel 100) to the display panel 100 so that the display panel 100 displays the screen. The touch control and display driver integrated chip 200 is also configured to provide a touch drive signal to the display panel 100 to perform touch drive on the touch structure 1, and receive a touch sensing signal fed back by the display panel 100, and determine the touch position (i.e., obtain a touch detection result) according to the received touch sensing signal to achieve touch detection.

[0162] The specific touch driving, touch detection, and display driving processes can be implemented based on the working processes of the existing touch driving chip and display driving chip, which will not be described in detail here.

[0163] In some embodiments, Figure 2As shown, the touch control structure 1 includes a plurality of touch control electrodes D disposed in the display area AA.

[0164] Exemplarily, the touch electrode D is configured to generate and transmit a touch sensing signal, and receive a touch driving signal.

[0165] For example, the touch electrode D generates a touch sensing signal when a finger touches the display panel 100 , and transmits the touch sensing signal to the touch and display driver integrated chip 200 .

[0166] In some embodiments, the touch structure is a self-capacitive touch structure.

[0167] In some other embodiments, the touch structure 1 is a mutual capacitive touch structure.

[0168] For example, Figure 2 and Figure 3 As shown, the plurality of touch electrodes D include a plurality of first touch electrodes 1 a and a plurality of second touch electrodes 1 c , and the first touch electrodes 1 a and the second touch electrodes 1 c are electrically insulated.

[0169] In some examples, such as Figure 2 and Figure 3 As shown, a plurality of first touch electrodes 1a are arranged at intervals along a first direction X, any two adjacent first touch electrodes 1a are connected, for example, by a first connecting portion 1b, and a plurality of first touch electrodes 1a and a plurality of first connecting portions 1b alternately arranged along the first direction X form a first touch channel 11. Each first touch channel 11 extends along the first direction X, and the touch structure 1 includes a plurality of first touch channels 11 arranged at intervals along a second direction Y.

[0170] In some examples, such as Figure 2 and Figure 3 As shown, a plurality of second touch electrodes 1c are arranged at intervals along the second direction Y, any two adjacent second touch electrodes 1c are connected, for example, by a second connecting portion 1d, and a plurality of second touch electrodes 1c and a plurality of second connecting portions 1d alternately arranged along the second direction Y form a second touch channel 12. Each second touch channel 12 extends along the second direction Y, and the touch structure 1 includes a plurality of second touch channels 12 arranged at intervals along the first direction X.

[0171] Exemplarily, one of the first touch electrode 1a and the second touch electrode 1c is, for example, a touch drive electrode Tx, and the other is a touch sensing electrode Rx. When an electrical signal is transmitted on the first touch electrode 1a and the second touch electrode 1c, mutual capacitance will be generated between the adjacent first touch electrode 1a and the second touch electrode 1c. When a finger touches the display panel 100, the finger will take away the charge on the touch electrode, causing the mutual capacitance value between the touch electrodes D at the touch position to change. According to the change in the mutual capacitance value between the touch electrodes D, the touch position of the finger can be identified, thereby realizing the touch function of the display panel 100.

[0172] In some examples, such as Figure 2 As shown, the display panel 100 also includes a plurality of first-type touch leads, such as first touch leads 2, one end of each first-type touch lead is connected to a first touch channel 11, and the other end is connected to a touch driver chip (such as a touch and display driver integrated chip 200).

[0173] In some examples, such as Figure 2 As shown, the display panel 100 also includes a plurality of second-type touch leads, the second-type touch leads are, for example, at least one of the second touch lead 4, the third touch lead 5 or the fourth touch lead 8, and the third touch lead 5 and the fourth touch lead 8 do not exist at the same time in the display panel 100, one end of each of the second-type touch leads is connected to a second touch channel 12, and the other end is connected to a touch driver chip (for example, a touch and display driver integrated chip 200).

[0174] In some embodiments, Figure 2 , Figures 8 to 19 As shown, the display panel 100 at least includes a plurality of data pins 32 and a plurality of first touch pins 31. The first touch pins 31 are connected to the touch structure 1, and each first touch pin 31 is electrically connected to a first touch channel 11 through, for example, a first touch lead 2, one end of the first touch lead 2 is connected to a first touch channel 11, and the other end is connected to a first touch pin 31. The first touch pin 31 is configured to receive a first touch signal, and transmit the first touch signal to the touch structure 1 through the first touch lead 2.

[0175] The multiple pixels within the display area AA of the display panel 100 are arranged in multiple rows and columns, for example. Each data pin 32 can be electrically connected to a row of pixels or a column of pixels. The data pin 32 is configured to receive the data signal required to display the picture and transmit the data signal to the display panel 100 (for example, to the pixel corresponding to the data pin 32).

[0176] Exemplarily, the plurality of pixels are divided into a plurality of groups, each group of pixels includes a plurality of adjacent pixels, and each data pin 32 may be electrically connected to a row of pixels or a column of pixels. Each group of pixels may include two, three, four or more adjacent pixels.

[0177] Accordingly, the touch control and display driver integrated chip 200 includes at least a plurality of data connection blocks 72 and a plurality of first touch connection blocks 71. The plurality of data connection blocks 72 of the touch control and display driver integrated chip 200 are respectively connected to a plurality of data pins 32 of the display panel 100, and each data connection block 72 is electrically connected to a row, a column or a group of pixels through the data pins 32. The data connection block 72 is configured to transmit display data signals to the pixels in the display panel 100. The plurality of first touch connection blocks 71 of the touch control and display driver integrated chip 200 are respectively connected to a plurality of first touch pins 31 of the display panel 100.

[0178] For example, Figure 2 As shown, the display panel 100 further includes a plurality of second touch pins 33. The second touch pins 33 are connected to the touch structure 1, or are not connected to the touch structure 1. When the second touch pins 33 are connected to the touch structure 1, each second touch pin 33 is electrically connected to a second touch channel 12 through, for example, a second touch lead 4, one end of the second touch lead 4 is connected to a second touch channel 12, and the other end is connected to a second touch pin 33.

[0179] Correspondingly, the touch control and display driver integrated chip 200 further includes a plurality of second touch control connection blocks 73 ; the plurality of second touch control pins 33 of the display panel 100 are respectively connected to the plurality of second touch control connection blocks 73 of the touch control and display driver integrated chip 200 .

[0180] In some embodiments, Figure 4 As shown, the display panel 100 includes a display area AA and a first binding area B1 located on one side of the display area AA for binding a driver chip (e.g., a touch and display driver integrated chip 200), and a plurality of first pins 3 are arranged in the first binding area B1, and the plurality of first pins 3 are arranged in N rows and in multiple columns. The plurality of first pins 3 include a first portion 3A, a second portion 3B, and a third portion 3C arranged in sequence along a first direction X. The first portion 3A extends along a first set direction, and the first set direction intersects with the first direction X; the first pins 3 in the second portion 3B extend along a second set direction, and the second set direction is perpendicular to the first direction X; the third portion 3C extends along a third set direction, and the third set direction intersects with the first direction X. Among them, the first set direction and the third set direction are symmetrical about the second set direction.

[0181] For example, the second setting direction may be perpendicular to the first direction X, and the symmetry axis of the second portion 3B along the column direction may be parallel to Figure 4 In this case, the first pins 3 included in the second part 3B extend along the second direction Y, for example, and the symmetry axis of the second part 3B may be parallel to Figure 4 The second direction Y shown in .

[0182] In some examples, the second portion 3B is arranged symmetrically about a reference center line C of the display panel 100 .

[0183] For example, the second setting direction may also intersect with the first direction X and be non-perpendicular to each other. Figure 4 The second direction Y shown in FIG. 1 intersects with the second direction Y shown in FIG. 1 and forms an acute angle, that is, the second set direction can also be an inclined direction. In this case, the second set direction is not a direction, but a direction along Figure 4 The second direction Y shown in FIG. 1 is symmetrical to the two directions.

[0184] With the second setting direction parallel to Figure 4 The second direction Y shown in FIG. 1 is used as an example for explanation.

[0185] For example, the boundaries of the first pins 3 in each row (eg Figure 4 The upper and lower boundaries of the first pins 3 shown in FIG. 1 are aligned along the row direction, and the boundaries of the first pins 3 in each column (such as Figure 4 The left and right boundaries of the first pin 3 shown in FIG. 1 are aligned along the column direction.

[0186] like Figure 4 As shown, the shape of the first pin 3 included in the second part 3B is, for example, a rectangle, and the shape of the first pin 3 included in the first part 3A and the third part 3C is, for example, a parallelogram.

[0187] The shapes of the first portion 3A, the second portion 3B and the third portion 3C include but are not limited to the above examples, as long as they can be effectively connected to the driver chip.

[0188] In some examples, such as Figure 4 As shown, the first portion 3A extends obliquely, and the upper end of the first portion 3A is farther away from the first frame area K1 than the lower end; the second portion 3B extends vertically, and the upper end and the lower end of the second portion 3B are at the same or substantially the same distance from the first frame area K1; the third portion 3C extends obliquely, and the upper end of the third portion 3C is closer to the first frame area K1 than the lower end. Among the N rows of first pins 3 in the first binding area B1, from the first row to the Nth row of first pins 3 from top to bottom, the distance between the two first pins 3 farthest apart along the first direction X gradually increases.

[0189] The upper end and the lower end here refer to the first pin 3 along the Figure 4 The upper and lower ends shown in .

[0190] In other examples, the first portion 3A is, for example, extended obliquely, and the upper end of the first portion 3A is closer to the first border area K1 than the lower end; the second portion 3B is, for example, extended vertically, and the upper end and the lower end of the second portion 3B are at the same or substantially the same distance from the first border area K1; the third portion 3C is, for example, extended obliquely, and the upper end of the third portion 3C is farther away from the first border area K1 than the lower end. Among the N rows of first pins 3 in the first binding area B1, the distance between the two farthest first pins 3 from the first row to the Nth row of first pins 3 from top to bottom along the first direction X gradually decreases.

[0191] During the preparation of the display device 1000, for example, in the process of correspondingly connecting the touch and display driver integrated chip 200 and the display panel 100, for example, a bonding process is used to correspondingly connect and bind the pins on the display panel 100 (for example, the first pin 3 and the second pin 6) and the connecting blocks (for example, the first connecting block 7 and the second connecting block 8) on the touch and display driver integrated chip 200.

[0192] For example, an ACF (Anisotropic Conductive Film) is attached to the first binding area B1 of the display panel 100, and then the touch control and display driver integrated chip 200 is pressed onto the ACF by a thermo-compression process, so that the touch control and display driver integrated chip 200 is correspondingly connected to the display panel 100. A large amount of heat is generated during the thermo-compression process, and after the touch control and display driver integrated chip 200 is correspondingly connected to the display panel 100, the temperature gradually drops and returns to room temperature.

[0193] The display panel 100 includes a substrate 10, for example, of PI, and a plurality of first pins 3, for example, of Figure 4In the arrangement extending in the vertical direction in the embodiment, when the display panel 100 and the touch and display driver integrated chip 200 are bound, a large temperature change will occur in the first binding area B1. During the temperature change, the substrate 10 in the first binding area B1 and its surrounding parts will expand and contract under the influence of temperature, so that the pins in the first binding area B1 (such as the first pin 3 and the second pin 6, etc.) and the connecting blocks (such as the first connecting block 7 and the second connecting block 8, etc.) on the touch and display driver integrated chip 200 will be offset. For example, after the offset occurs between one of the first pins 3 and one of the first connecting blocks 7, the overlapping area of ​​the corresponding connecting parts decreases by more than 80% compared with the set overlapping area. In this way, on the one hand, the connection stability of the corresponding first pin 3 and the first connecting block 7 decreases, and there is a risk of disconnection between the two, which affects the stability of signal transmission; on the other hand, due to the reduction of the overlapping area of ​​the corresponding connecting parts, the resistance value of the part increases, thereby increasing the power consumption of the display panel 100.

[0194] When the substrate 10 expands and contracts in the first binding area B1 under the influence of temperature, the first pin 3 closer to the middle position of the first binding area B1 is less affected, and the first pin 3 farther away from the middle position (the first pin 3 closer to the first border area K1 and the first pin 3 closer to the second border area K2) is more affected and is more likely to have poor alignment.

[0195] By setting the portion (second portion 3B) of the plurality of first pins 3 located near the reference center line C of the display panel 100 to extend in the vertical direction, and setting the first pins 3 on both sides (first portion 3A and third portion 3C) to extend obliquely (the extension direction intersects with the extension direction of the second portion 3B and forms an acute angle). In this way, even if the substrate 10 expands and contracts under the influence of temperature, the first pins 3 extending obliquely on both sides are less affected by the expansion and contraction of the substrate 10 than the design extending in the vertical direction, and the pins on the display panel 100 and the connection blocks on the touch and display driver integrated chip 200 can still ensure good alignment connection, thereby ensuring the stability and reliability of signal transmission.

[0196] It should be noted that the multiple first pins 3 described here include a first part 3A, a second part 3B and a third part 3C. This is a grouping for the convenience of clearly describing how the extension direction of the multiple first pins 3 in the display panel 100 is set, and does not mean that the multiple first pins 3 are actually divided into three parts.

[0197] Accordingly, in some embodiments, Figure 5As shown, the touch control and display driver integrated chip 200 includes a first output area S1, and a plurality of first connection blocks 7 are arranged in the first output area S1. The plurality of first connection blocks 7 are arranged in N rows and in a plurality of columns. The plurality of first connection blocks 7 include a first portion 7A, a second portion 7B, and a third portion 7C arranged in sequence from the right end to the left end of the touch control and display driver integrated chip 200.

[0198] The first part 7A of the multiple first connecting blocks 7 of the touch and display driver integrated chip 200 is connected to the first part 3A of the multiple first pins 3 of the display panel 100; the second part 7B of the multiple first connecting blocks 7 is connected to the second part 3B of the multiple first pins 3; the third part 7C of the multiple first connecting blocks 7 is connected to the third part 3C of the multiple first pins 3.

[0199] The first portion 7A extends along a first set direction, which intersects with the length direction of the touch and display driver integrated chip 200; the second portion 7B extends along a second set direction, which is perpendicular to the length direction of the touch and display driver integrated chip 200; the third portion 7C extends along a third set direction, which intersects with the length direction of the touch and display driver integrated chip 200. The first set direction and the third set direction are symmetrical about the second set direction.

[0200] It should be noted that the multiple first connection blocks 7 described here include the first part 7A, the second part 7B and the third part 7C, which are grouped for the purpose of clearly describing how the extension direction of the multiple first connection blocks 7 in the touch and display driver integrated chip 200 is set, and do not mean that the multiple first connection blocks 7 are actually divided into three parts. And the first part 7A, the second part 7B and the third part 7C described here (the multiple first connection blocks 7 include the first part 7A, the second part 7B and the third part 7C) are different from the first part 3A, the second part 3B and the third part 3C described above (the multiple first pins 3 of the display panel 100 include the first part 3A, the second part 3B and the third part 3C).

[0201] The first set direction and the second set direction described here are for the purpose of clearly describing the extension directions of the multiple first connecting blocks 7 in the touch and display driver integrated chip 200, and distinguishing the different extension directions of the three parts of the first connecting blocks 7. They are also different from the first set direction and the second set direction in the previous description of the extension directions of the multiple first pins 3 in the display panel 100.

[0202] For example, the second setting direction may be perpendicular to the first direction X, that is, the second setting direction may be parallel to Figure 5In this case, the first connecting blocks 7 included in the second part 7B extend along the second direction Y, for example, and the symmetry axis of the second part 7B may be parallel to Figure 5 The second direction Y shown in .

[0203] For example, the second setting direction may also intersect with the first direction X and be non-perpendicular to each other. Figure 5 The second direction Y shown in FIG. 1 intersects with the second direction Y shown in FIG. 1 and forms an acute angle, that is, the second set direction can also be an inclined direction. In this case, the second set direction is not a direction, but a direction along Figure 5 The second direction Y shown in FIG. 1 is symmetrical to the two directions.

[0204] With the second setting direction parallel to Figure 5 The second direction Y shown in FIG. 1 is used as an example for explanation.

[0205] For example, along Figure 5 In the direction where the right side in FIG. 1 points to the left side, the plurality of first connection blocks 7 are sequentially divided into a first part 7A, a second part 7B and a third part 7C.

[0206] The plurality of first connection blocks 7 in the first output area S1 are arranged in N rows and in a plurality of columns, and the boundaries of the first connection blocks 7 in each row (eg Figure 5 The upper and lower boundaries of the first connection blocks 7 shown in FIG. 1 are aligned in the row direction, and the boundaries of the first connection blocks 7 in each column (such as Figure 5 The left and right boundaries of the first connecting block 7 shown in FIG. 8 are aligned along the column direction.

[0207] like Figure 5 As shown, the shape of the first connection block 7 included in the second part 7B is, for example, a rectangle, and the shape of the first connection block 7 included in the first part 7A and the third part 7C is, for example, a parallelogram.

[0208] In some examples, such as Figure 5 As shown, the first part 7A extends obliquely, and the upper end of the first part 7A is farther away from the right end of the touch and display driver integrated chip 200 than the lower end; the second part 7B extends vertically, and the upper end and the lower end of the second part 7B are, for example, at the same or substantially the same distance from the right end of the touch and display driver integrated chip 200; the third part 7C extends obliquely, and the upper end of the third part 7C is closer to the right end of the touch and display driver integrated chip 200 than the lower end. Among the N rows of first connection blocks 7 in the first output area S1, from the first row to the Nth row of first connection blocks 7 from top to bottom, the distance between the two farthest first connection blocks 7 along the first direction X gradually increases.

[0209] The upper end and the lower end mentioned here refer to the first connecting block 7 along the Figure 5The upper and lower ends shown in .

[0210] In other examples, the first portion 7A extends obliquely, and the upper end of the first portion 7A is closer to the right end of the touch and display driver integrated chip 200 than the lower end; the second portion 7B extends vertically, and the upper end and the lower end of the second portion 7B are, for example, at the same or substantially the same distance from the right end of the touch and display driver integrated chip 200; the third portion 7C extends obliquely, and the upper end of the third portion 7C is farther away from the right end of the touch and display driver integrated chip 200 than the lower end. Among the N rows of first connection blocks 7 in the first output area S1, the distance between the two farthest first connection blocks 7 from the first row to the Nth row of first connection blocks 7 from top to bottom along the first direction X gradually decreases.

[0211] As mentioned above, a large amount of heat is generated during the process of binding the touch control and display driver integrated chip 200 to the display panel 100. After the touch control and display driver integrated chip 200 and the display panel 100 are connected accordingly, the temperature gradually drops back to room temperature. During the temperature change process, the connection block on the touch control and display driver integrated chip 200 and the pin on the display panel 100 will be offset.

[0212] By setting the portion (second portion 7B) of the plurality of first connection blocks 7 located in the middle of the touch and display driver integrated chip 200 to extend in the vertical direction, and setting the first connection blocks 7 on both sides (first portion 7A and third portion 7C) to extend obliquely (the extension direction intersects with the extension direction of the second portion 7B and forms an acute angle), in this way, even if the substrate 10 expands and contracts under the influence of temperature, the pins on the display panel 100 and the connection blocks on the touch and display driver integrated chip 200 can still ensure good alignment connection, thereby ensuring the stability and reliability of signal transmission.

[0213] In some embodiments, in the display panel 100, as Figure 4 As shown, the plurality of second pins 6 include a first group and a second group respectively arranged in two second binding areas B2. The first group extends along a fourth setting direction, which intersects with the first direction X; the second group extends along a fifth setting direction, which intersects with the first direction X. Wherein, when the second direction Y is perpendicular to the first direction X, the fourth setting direction and the fifth setting direction are symmetrical about the second direction Y.

[0214] For example, the boundaries of the second pins 6 in each row (eg Figure 4 The upper and lower boundaries of the second pins 6 shown in FIG. 1 are arranged in parallel, and the boundaries of the second pins 6 in each column (such as Figure 4 The left and right boundaries of the second pin 6 shown in FIG. 1 are aligned along the column direction.

[0215] Exemplarily, the shape of the second pin 6 is, for example, a parallelogram.

[0216] As mentioned above, a large amount of heat is generated during the process of binding the touch and display driver integrated chip 200 to the display panel 100. After the touch and display driver integrated chip 200 and the display panel 100 are connected accordingly, the temperature gradually drops and returns to room temperature. During the temperature change, the expansion and contraction deformation of the substrate 10 will also cause the positions of the multiple second pins 6 in the second binding area B2 to deviate from the set positions, causing the connection blocks on the touch and display driver integrated chip 200 and the pins on the display panel 100 to deviate from each other.

[0217] By setting the second pin 6 to extend obliquely (the extension direction forms an acute angle with the first direction X), even if the substrate 10 expands or contracts under the influence of temperature, the inclined design of the second pin 6 makes it less affected by the expansion and contraction of the substrate 10, and the corresponding connecting block on the touch and display driver integrated chip 200 can still ensure good alignment connection, thereby ensuring the stability and reliability of signal transmission.

[0218] Accordingly, in some embodiments, in the touch control and display driver integrated chip 200, for example Figure 5 As shown, the plurality of second connection blocks 8 include a first group and a second group respectively arranged in two second output areas S2. The first group extends along a fourth setting direction, which intersects with the first direction X; the second group extends along a fifth setting direction, which intersects with the first direction X. Wherein, when the second direction Y is perpendicular to the first direction X, the fourth setting direction and the fifth setting direction are symmetrical about the second direction Y.

[0219] Exemplarily, the plurality of second connection blocks 8 included in the first group are arranged in at least one row along the second direction Y, and each second connection block 8 extends along the fourth set direction; the plurality of second connection blocks 8 included in the second group are arranged in at least one row along the second direction Y, and each second connection block 8 extends along the fifth set direction. Figure 5 As shown, the shape of each second connecting block 8 is, for example, a parallelogram.

[0220] As mentioned above, by setting the second connecting block 8 to extend at an angle, the positional deviation of the pins on the display panel 100 caused by the expansion and contraction of the substrate 10 under the influence of temperature can be reduced, thereby reducing the impact on the binding reliability of the touch and display driver integrated chip 200, thereby ensuring the reliability of the alignment connection between the display panel 100 and the touch and display driver integrated chip 200, and further ensuring the stability and reliability of signal transmission.

[0221] In some embodiments, Figure 2As shown, the display panel 100 also includes a first border area K1 and a second border area K2 respectively located on opposite sides of the display area AA in the first direction X, a third border area K3 and a fourth border area K4 respectively located on opposite sides of the display area AA in the second direction Y, and a first binding area B1 located on the non-display surface of the display panel 100 opposite to the display surface, and the first binding area B1 and the fourth border area K4 are arranged on the same side of the display panel 100.

[0222] The first direction X is perpendicular to the second direction Y. The first binding area B1 includes a first pin area J1 , a second pin area J2 and a third pin area J3 which are sequentially arranged along the first direction X and in a direction from the first frame area K1 to the second frame area K2 .

[0223] like Figure 2 and Figure 4 As shown, the display panel 100 further includes: a touch structure 1 and a plurality of first touch leads 2. The touch structure 1 is disposed in the display area AA, and the plurality of first touch leads 2 are connected to the touch structure 1. The plurality of first touch leads 2 are divided into two groups and are led out from the first frame area K1 and the second frame area K2, respectively, and extend to the first pin area J1 and the third pin area J3.

[0224] The plurality of first pins 3 are disposed in the first binding area B1 , and the plurality of first pins 3 are arranged in a plurality of rows, and the row direction intersects with the first direction X.

[0225] The plurality of first pins 3 include: a plurality of first touch pins 31 and a plurality of data pins 32. The first touch pins 31 are configured to receive a first touch signal and transmit the first touch signal to the touch structure 1 through the first touch lead 2. The plurality of data pins 32 are arranged in the second pin area J2, and are configured to receive a data signal required for displaying a picture and transmit the data signal to the display panel 100. The plurality of first touch pins 31 are divided into two groups, which are respectively arranged in the first pin area J1 and the third pin area J3, and are respectively connected to the two groups of first touch leads 2.

[0226] Exemplarily, the angle formed by the arrangement direction of each column of the first pins 3 and the first direction X is greater than or equal to 60° and less than or equal to 90°.

[0227] In some examples, the angle formed by the arrangement direction of each column of the first pins 3 and the first direction X is greater than or equal to 75° and less than or equal to 90°.

[0228] It should be noted that the angle range of the angle formed by the arrangement direction of each column of the first pins 3 and the first direction X can be adaptively adjusted according to the specific design, which is only used as an exemplary description here and is not a limitation of the present disclosure. The first binding area B1 and the fourth border area K4 are arranged on the same side of the display panel 100, which means that the first binding area B1 and the fourth border area K4 are both located on the side of the display panel 100 for binding the driver chip (for example, the touch and display driver integrated chip 200).

[0229] Exemplarily, one end of each first touch lead 2 is connected to a first touch channel 11, and the other end is connected to a first touch pin 31. The specific connection between the first touch lead 2 and the first touch channel 11 and the first touch pin 31 is described later and will not be described here.

[0230] It should be noted that the plurality of first pins 3 are arranged in a plurality of columns, and the column direction intersects with the first direction X. The column direction refers to the arrangement direction of the plurality of first pins 3 arranged in a column. The arrangement directions of the plurality of columns of first pins 3 may be the same or not completely the same, that is, the column direction is not necessarily unique. There may be one, two or more column directions, which are specifically determined according to the specific arrangement of the plurality of first pins 3. The arrangement of the plurality of first pins 3 is described in detail later, and will not be introduced here.

[0231] Exemplarily, the plurality of first touch pins 31 are divided into two groups and are respectively arranged in the first pin area J1 and the third pin area J3 , wherein the number of the two groups of first touch pins 31 may be the same or different, depending on actual needs.

[0232] The following description is made by taking the two groups of first touch pins 31 having the same number as an example. The grouping and arrangement of the first touch pins 31 will be described in detail later, and will not be described in detail here.

[0233] For example, Figure 2 As shown, the display panel 100 further includes a bending area DD. During the preparation of the display panel 100, the fourth frame area K4, the bending area DD and the first binding area B1 are all located on one side of the display surface of the display panel 100. The bending area DD is located on the side of the fourth frame area K4 away from the display area AA, and is located between the fourth frame area K4 and the first binding area B1. The display panel 100, for example, includes a plurality of signal lines (such as a first touch lead 2, a second touch lead 4, a third touch lead 5 and a fourth touch lead 8, etc.), one end of a portion of the plurality of signal lines is electrically connected to the touch structure 1, and the other end extends to the first binding area B1 and is electrically connected to a plurality of first pins 3.

[0234] The surface of one side of the display panel 100 on which the touch structure 1 is provided is the display surface of the display panel 100. In the process of preparing the display device 1000, before the display panel 100 and the touch and display driver integrated chip 200 are connected, the bending area DD and the first binding area B1 of the display panel 100 are both located on the display surface side of the display panel 100. After the touch and display driver integrated chip 200 is bound to the display panel 100 in the first binding area B1, the display panel 100 is bent along the boundary line of the bending area DD close to the display area AA side and the boundary line away from the display area AA side, so that the bending area DD and the part of the display panel 100 away from the display area AA are bent toward the non-display surface of the display panel 100 opposite to the display surface. In this way, the portion where the touch and display driver integrated chip 200 is set is bent to the non-display surface of the display panel 100 opposite to the display surface, thereby reducing the area ratio of the non-display area on the display surface side of the display panel 100, and then increasing the area ratio of the display area AA of the display panel 100 on the display surface, thereby improving the visual experience of the display screen of the display panel 100.

[0235] Exemplarily, when the multiple first touch leads 2 are divided into two groups and respectively led out from the first frame area K1 and the second frame area K2, the number of first touch leads 2 in the two groups is the same or approximately the same. In this way, the number of wirings of the multiple first touch leads 2 in the first frame area K1 and the second frame area K2 is the same or approximately the same, which is conducive to ensuring that the non-display area of ​​the display surface of the display panel 100 is symmetrically and evenly distributed on both sides of the display area AA, thereby ensuring the aesthetic appearance and picture display effect of the display panel 100.

[0236] Accordingly, in some embodiments, Figure 5 As shown, the first output area S1 of the touch and display driver integrated chip 200 includes a first connection area L1, a second connection area L2 and a third connection area L3 which are arranged in sequence along a first direction X and from the right end to the left end of the touch and display driver integrated chip 200. The first direction X is parallel to the length direction of the touch and display driver integrated chip 200.

[0237] The plurality of first connection blocks 7 are arranged in a plurality of columns, and the column direction and the first direction X intersect.

[0238] The plurality of first connection blocks 7 include: a plurality of first touch connection blocks 71 and a plurality of data connection blocks 72. The plurality of first touch connection blocks 71 are divided into two groups and are respectively arranged in the first connection area L1 and the third connection area L3, and are configured to output the first touch signal. The plurality of data connection blocks 72 are arranged in the second connection area L2, and are configured to output the data signal required for displaying the screen.

[0239] The plurality of first connection blocks 7 are arranged in a plurality of columns, and the column direction intersects with the first direction X, which means that the arrangement direction of the first connection blocks 7 in each column intersects with the first direction X. The arrangement directions of the plurality of columns of first connection blocks 7 may be the same or not completely the same, that is, the column direction is not necessarily unique, and there may be one, two or more column directions, which are specifically determined according to the specific arrangement of the plurality of first connection blocks 7. The arrangement of the plurality of first connection blocks 7 is described in detail below and will not be described here.

[0240] Exemplarily, the angle formed by the arrangement direction of each column of the first connection blocks 7 and the first direction X is greater than or equal to 60° and less than or equal to 90°.

[0241] In some examples, the angle formed by the arrangement direction of each column of the first connection blocks 7 and the first direction X is greater than or equal to 75° and less than or equal to 90°.

[0242] It should be noted that the angle range formed by the arrangement direction of each column of first connecting blocks 7 and the first direction X can be adaptively adjusted according to the specific design, which is only used as an exemplary description and not as a limitation to the present disclosure.

[0243] Exemplarily, when the touch and display driver integrated chip 200 is connected to the display panel 100 , one side of the touch and display driver integrated chip 200 with multiple first connection blocks 7 faces the display panel 100 and is connected to multiple first pins 3 set on the display panel 100 .

[0244] The touch and display driver integrated chip 200 provided in some embodiments of the present disclosure, compared with the conventional display driver chip, adds a touch driver unit (including the first touch connection block 71 and the second touch connection block 72, and other touch control units, etc., the control principle is the same as that of the touch driver chip, which will not be repeated here), and sends a touch drive signal to the display panel 100 through the first touch connection block 71 and the second touch connection block 72, thereby driving the touch structure 1 in the display panel 100 to realize the touch function. The display driver function and the touch driver function are integrated on a single chip, which increases the integration of the display device 1000 and helps reduce the manufacturing cost of the display device 1000. At the same time, when the display device 1000 adopts a touch and display driver integrated chip 200, a single touch and display driver integrated chip 200 is connected to realize the display driving function and the touch driving function of the display panel 100, and is connected to the display panel 100 and the display driver chip and the touch driver chip are respectively connected, which can reduce the number of signal lines used to connect to the chip in the display panel 100 (for example, signal lines connected to the input connection blocks in the driver chip), thereby reducing the wiring area of ​​the border area of ​​the display panel 100, which is conducive to realizing the narrow border design of the display panel 100 and the display device 100.

[0245] In some embodiments, in the touch control and display driver integrated chip 200 , the touch control and display driver integrated chip 200 further includes an input area R1 , which is arranged opposite to the first output area S1 .

[0246] Exemplarily, a plurality of input connection blocks are provided in the input region R1. The input connection blocks include a reset connection block Rst, a first power connection block Pwr1, a data transmission connection block IIC (Inter-Integrated Circuit, serial communication bus), a communication connection block SPI (Serial Peripheral Interface, serial peripheral interface) and an interrupt request connection block INT (Interrupt, interrupt) and other connection blocks related to the basic functional units of the chip.

[0247] In some examples, the input connection block also includes a processor connection block MIPI (Mobile Industry Processor Interface).

[0248] Exemplarily, the input connection block also includes: a second power connection block Pwr2, an interface connection block I / F (Interface), a voltage conversion connection block C / P (Charge Pump), and other connection blocks related to the touch driving unit.

[0249] The power connection block is configured to be connected to a power source to supply power to the touch control and display driver integrated chip 200 .

[0250] It should be noted that if Figure 5 As shown, the touch control and display driver integrated chip 200 further includes an input area R1, and the first output area S1 and the input area R1 are respectively arranged on opposite sides of the touch control and display driver integrated chip 200, and the side of the first output area S1 is called the upper end of the touch control and display driver integrated chip 200, and correspondingly, the side of the input area R1 is the lower end of the touch control and display driver integrated chip 200. The right end and the left end in the direction from the right end to the left end of the touch control and display driver integrated chip 200 refer to, as shown in FIG. Figure 5 When looking at the touch control and display driver integrated chip 200 from the side surface where the plurality of first connection blocks 7 are arranged on the touch control and display driver integrated chip 200, the right end and the left end of the touch control and display driver integrated chip 200 are shown. Figure 2 As shown in FIG. 1 , after the touch control and display driver integrated chip 200 is connected to the display panel 100 correspondingly, the right end and the left end of the touch control and display driver integrated chip 200 are Figure 5 The opposite is true.

[0251] Exemplarily, the plurality of first touch connection blocks 71 are divided into two groups and are respectively arranged in the first connection area L1 and the third connection area L3 , wherein the number of the two groups of first touch connection blocks 71 may be the same or different, depending on actual needs.

[0252] The following description is made by taking the two groups of first touch connection blocks 71 having the same number as an example. The grouping and arrangement of the first touch connection blocks 71 will be described in detail later, and will not be described in detail here.

[0253] In some embodiments, Figure 4 As shown, the display panel 100 includes a plurality of first pins 3 arranged in N rows along a first direction X.

[0254] It should be noted that the multiple first pins 3 included in the display panel 100 described here are arranged in N rows along the first direction X, which means that the multiple first pins 3 included in the display panel 100 are arranged in N rows, and the multiple first pins 3 in each row are arranged in sequence along the first direction X.

[0255] Exemplarily, N≥3.

[0256] When N rows of first pins 3 are provided in the display panel 100, the specific value of N is related to the size of the display panel 100 along the first direction X, the number of first pins 3 that can be arranged in each row of the display panel 100 along the first direction X, and the number of first pins 3 required for the display panel 100.

[0257] For example, the size of the display panel 100 along the first direction X is a, and the display panel 100 can arrange b first pins 3 in each row. The number of first pins 3 required for the display panel 100 is less than or equal to b. At this time, the multiple first pins 3 included in the display panel 100 can be arranged in 1 row or more rows; the number of first pins 3 required for the display panel 100 is 2b+k, 1≤k≤b, at this time, the multiple first pins 3 included in the display panel 100 can be arranged in 3 rows or more rows; the number of first pins 3 required for the display panel 100 is equal to 3b, at this time, the multiple first pins 3 included in the display panel 100 can be arranged in 3 rows or more rows.

[0258] It can be understood that when the number of first pins 3 required by the display panel 100 is greater than b and less than 2b, the plurality of first pins 3 included in the display panel 100 can be arranged in 2 or more rows along the first direction X. The number of first pins 3 provided on the display panel 100 is greater than or equal to the number of first pins 3 in the display panel 100 configured to transmit electrical signals (e.g., data signals, first touch signals, second touch signals, etc.).

[0259] The case where the plurality of first pins 3 included in the display panel 100 are arranged in N rows along the first direction X includes but is not limited to the above case, which is specifically designed according to actual needs and is only used as an example of a possible implementation method and is not intended to limit the specific implementation methods of the present disclosure.

[0260] Accordingly, in some embodiments, Figure 5 As shown, the touch control and display driver integrated chip 200 includes a plurality of first connection blocks 7 arranged in N rows along the first direction X.

[0261] Exemplarily, N≥3.

[0262] It should be noted that the multiple first connection blocks 7 included in the touch and display driver integrated chip 200 described here are arranged into N rows along the first direction X, which means that the multiple first connection blocks 7 included in the touch and display driver integrated chip 200 are arranged into N rows, and the multiple first connection blocks 7 in each row are arranged in sequence along the first direction X.

[0263] In the case where N rows of first connection blocks 7 are provided in the touch and display driver integrated chip 200, the specific value of N is related to the size of the touch and display driver integrated chip 200 along the first direction X, the number of first connection blocks 7 that can be arranged in each row of the touch and display driver integrated chip 200 along the first direction X, and the number of first connection blocks 7 required by the touch and display driver integrated chip 200. For details, refer to the above description of the correlation between the number of first pins 3 in the display panel 100 and the specific value of N, which will not be repeated here.

[0264] The specific arrangement and number of rows of the multiple first connection blocks 7 included in the touch and display driver integrated chip 200 are designed accordingly according to actual needs, which is only used as an example of a possible implementation method and is not intended to limit the specific implementation methods of the present disclosure.

[0265] like Figure 2 As shown, when the touch control and display driver integrated chip 200 is applied to the display device 1000, the touch control and display driver integrated chip 200 included in the display device 1000 and the display panel 100 connected thereto have a matching design. In order to clearly describe the connection method between the display panel 100 and the touch control and display driver integrated chip 200, the following embodiments of the present disclosure provide a touch control and display driver integrated chip 200 having a design that matches the first binding area B1 of the display panel 100 as an example for illustration.

[0266] It can be understood that the setting method of the connection area (such as the division of the first connection area L1, the second connection area L2 and the third connection area L3) on the touch and display driver integrated chip 200, and the specific arrangement method of the connection blocks (such as the first connection block 7 and the second connection block 8, etc.), include but are not limited to the methods provided in the embodiments of the present disclosure.

[0267] In some embodiments, Figure 4 As shown, the first binding area B1 of the display panel 100 further includes a fourth pin area J4 and a fifth pin area J5. Along the first direction X, the fourth pin area J4 and the fifth pin area J5 are respectively located on both sides of the second pin area J2.

[0268] For example, Figure 4 As shown, the first pin area J1 and the fourth pin area J4 are located at the same side of the second pin area J2, and the third pin area J3 and the fifth pin area J5 are located at the same side of the second pin area J2.

[0269] In some examples, such as Figure 4 As shown, the fourth pin area J4 is located between the first pin area J1 and the second pin area J2, and the fifth pin area J5 is located between the second pin area J2 and the third pin area J3.

[0270] In some other examples, the fourth pin region J4 is located on a side of the first pin region J1 away from the second pin region J2, and the fifth pin region J5 is located on a side of the third pin region J3 away from the second pin region J2.

[0271] In some other examples, the fourth pin region J4 is located between the first pin region J1 and the second pin region J2 , and the fifth pin region J5 is located on a side of the third pin region J3 away from the second pin region J2 .

[0272] In some further examples, the fourth pin region J4 is located at a side of the first pin region J1 away from the second pin region J2, and the fifth pin region J5 is located between the second pin region J2 and the third pin region J3.

[0273] It should be noted that the relative positions between the pin areas (such as the first pin area J1, the second pin area J2, the third pin area J3, the fourth pin area J4 and the fifth pin area J5, etc.) in the first output area S1 include but are not limited to the above situations, and are specifically designed according to actual needs. They are only used as examples of possible implementations and are not intended to limit the specific implementations of the present disclosure.

[0274] The following description will be made by taking an example that the fourth pin area J4 is located between the first pin area J1 and the second pin area J2 , and the fifth pin area J5 is located between the second pin area J2 and the third pin area J3 .

[0275] Accordingly, in some embodiments, Figure 5 As shown, the first output area S1 of the touch and display driver integrated chip 200 further includes a fourth connection area L4 and a fifth connection area L5. Along the first direction X, the fourth connection area L4 and the fifth connection area L5 are respectively located on both sides of the second connection area L2.

[0276] Exemplarily, the first connection region L1 and the fourth connection region L4 are located on the same side of the second connection region L2, and the third connection region L3 and the fifth connection region L5 are located on the same side of the second connection region L2.

[0277] In some examples, such as Figure 5 As shown, the fourth connection region L4 is located between the first connection region L1 and the second connection region L2, and the fifth connection region L5 is located between the second connection region L2 and the third connection region L3.

[0278] In some other examples, the fourth connection region L4 is located on a side of the first connection region L1 away from the second connection region L2, and the fifth connection region L5 is located on a side of the third connection region L3 away from the second connection region L2.

[0279] In some other examples, the fourth connection region L4 is located between the first connection region L1 and the second connection region L2, and the fifth connection region L5 is located on a side of the third connection region L3 away from the second connection region L2.

[0280] In some further examples, the fourth connection region L4 is located on a side of the first connection region L1 away from the second connection region L2, and the fifth connection region L5 is located between the second connection region L2 and the third connection region L3.

[0281] It should be noted that the relative positions between the connection areas (for example, the first connection area L1, the second connection area L2, the third connection area L3, the fourth connection area L4 and the fifth connection area L5, etc.) within the first binding area B1 include but are not limited to the above situations, and are designed accordingly according to actual needs. They are only used here as examples of possible implementation methods and are not intended to limit the specific implementation methods of the present disclosure.

[0282] It is understandable that when the touch and display driver integrated chip 200 is applied to the display device 1000, the touch and display driver integrated chip 200 and the display panel 100 included in the display device 1000 need to have a compatible design. In order to clearly describe the connection method between the display panel 100 and the touch and display driver integrated chip 200, the following is an example in which the fourth connection area L4 is located between the first connection area L1 and the second connection area L2, and the fifth connection area L5 is located between the second connection area L2 and the third connection area L3.

[0283] In some embodiments, Figure 2 and Figure 4As shown, the display panel 100 includes a plurality of first pins 3 and a plurality of second touch pins 33, which are divided into two groups and respectively arranged in the fourth pin area J4 and the fifth pin area J5. The second touch pins 33 are configured to receive a second touch signal and transmit the second touch signal to the touch structure 1.

[0284] In some embodiments, Figure 2 and Figure 4 As shown, the display panel 100 further includes: a plurality of second touch leads 4 connected to the touch structure 1. The plurality of second touch leads 4 are led out from the fourth frame area K4, and are divided into two groups and extend to the fourth pin area J4 and the fifth pin area J5 respectively. The two groups of second touch leads 4 are respectively connected to the two groups of second touch pins 33.

[0285] Exemplarily, one end of each second touch lead 4 is connected to a second touch channel 12, and the other end is connected to a second touch pin 33. The second touch pin 33 is configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 through the second touch lead 4.

[0286] For example, the second touch pin 33 is configured to receive a second touch signal and transmit the second touch signal to the second touch channel 12 through the second touch lead 4 .

[0287] The specific connection method between the second touch lead 4, the second touch channel 12 and the second touch pin 33 will be described later and will not be described here.

[0288] For example, when the plurality of second touch leads 4 are led out from the fourth frame area K4, the number of the two groups of second touch leads 4 may be the same or different. The grouping method of the plurality of second touch leads 4 is related to the specific arrangement method of the second touch pins 33 in the first binding area B1. The arrangement method of the plurality of second touch pins 33 is described in detail below and will not be described here.

[0289] When multiple second touch leads 4 are led out from the fourth frame area K4, the second touch leads 4 are led out from the fourth frame area K4 to the fourth pin area J4 and the fifth pin area J5 in the first binding area B1, and are connected to the corresponding second touch pins 33. In this way, the second touch leads 4 do not pass through the remaining frame areas (for example, the first frame area K1, the second frame area K2 and the third frame area K3) except the fourth frame area K4, thereby reducing the wiring area in the frame area, thereby reducing the frame width of the display panel 100, increasing the area ratio of the display area AA of the display panel 100 to the display surface, and then improving the viewing experience of the display screen of the display panel 100.

[0290] Accordingly, in some embodiments, Figure 5As shown, the multiple first connection blocks 7 included in the touch and display driver integrated chip 200 also include: multiple second touch connection blocks 73, which are divided into two groups and are respectively arranged in the fourth connection area L4 and the fifth connection area L5. The multiple second touch connection blocks 73 are configured to output second touch signals.

[0291] By setting the second touch connection block 73, when the touch and display driver integrated chip 200 is connected to the display panel 100 accordingly, the second touch signal is transmitted to the corresponding second touch pin 33 in the display panel 100 through the second touch connection block 73, and the second touch signal is transmitted to the touch structure 1 through the second touch pin 33 and the second touch lead 4, thereby realizing the touch driving function of the touch and display driver integrated chip 200 on the display panel 100.

[0292] In some embodiments, Figure 4 and Figure 6 As shown, the display panel 100 further includes two second binding areas B2, which are located on the side of the first binding area B1 away from the display area AA and are respectively arranged corresponding to the two ends of the first binding area B1. The display panel 100 further includes: a plurality of second pins 6, which are divided into two groups and respectively arranged in the two second binding areas B2. The second pins 6 are configured to receive a second touch signal and transmit the second touch signal to the touch structure 1, or are configured not to be connected to the touch signal line.

[0293] Exemplarily, when the second pin 6 is configured to receive the second touch signal and transmit the second touch signal to the touch structure 1, the display panel 100 further includes: a plurality of third touch leads 5 connected to the touch structure 1. The plurality of third touch leads 5 are led out from the third frame area K3, divided into two groups, respectively passing through the first frame area K1 and the second frame area K2, and respectively extending to the two second binding areas B2. The two groups of third touch leads 5 are respectively connected to the two groups of second pins 6.

[0294] Exemplarily, one end of each third touch lead 5 is connected to a second touch channel 12, and the other end is connected to a second pin 6. The second pin 6 is configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 through the third touch lead 5.

[0295] For example, the second pin 6 is configured to receive a second touch signal, and transmit the second touch signal to the second touch channel 12 through the third touch lead 5 .

[0296] The specific connection method between the third touch lead 5, the second touch channel 12 and the second pin 6 will be described later and will not be further described here.

[0297] Exemplarily, when the display panel 100 further includes a plurality of second touch pins 33 and a plurality of second pins 6 , at least one of the second touch pins 33 and the second pins 6 is configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 .

[0298] In some examples, such as Figure 6 As shown, the second touch pin 33 is configured to receive the second touch signal and transmit the second touch signal to the touch structure 1 through the second touch lead 4. The second pin 6 is configured to receive the second touch signal and transmit the second touch signal to the touch structure 1 through the third touch lead 5.

[0299] In this case, the two groups of second pins 6 are also respectively connected to the two groups of second touch pins 33. For example, each second touch pin 33 is connected to a second touch lead 4 and is also connected to a second pin 6 through a first connection line 20. It can be understood that in this case, each group of second touch pins 33 is connected to a group of second touch leads 4 and is also connected to a group of second pins 6 through a group of first connection lines 20, and the number of a group of second touch leads 4, second touch pins 33, third touch leads 5 and second pins 6 connected correspondingly is the same.

[0300] The specific corresponding connection method of a group of second touch leads 4, second touch pins 33, third touch leads 5 and second pins 6 connected correspondingly is described later and will not be described here.

[0301] When the display panel 100 includes multiple second touch leads 2 and multiple third touch leads 5, one end of each second touch channel 12 is connected to the corresponding second touch pin 33 through a second touch lead 2, and the other end is connected to the corresponding second pin 6 through a third touch lead 5. In this way, the second touch signal is transmitted from the second touch pin 33 and the second pin 6 to the two ends of the second touch channel 12 respectively, which can reduce the signal path loss of the second touch signal on the transmission path (for example, the second touch signal generates signal distortion during the transmission process due to the long transmission path, etc.), thereby ensuring the transmission reliability of the second touch signal.

[0302] In other examples, such as Figure 2 As shown, the second touch pin 33 is configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 through the second touch lead 4. The second pin 6 is configured not to be connected to the touch signal line.

[0303] When the second touch pin 33 is configured to receive the second touch signal and transmit the second touch signal to the touch structure 1, and the second pin 6 is configured not to be connected to the touch signal line, the display panel 100 may further include a plurality of fourth touch leads 8 connected to the touch structure 1. The plurality of fourth touch leads 8 are led out from the third frame area K3, and are divided into two groups and extend to the fourth pin area J4 and the fifth pin area J5 respectively. The two groups of fourth touch leads 8 are respectively connected to the two groups of second touch pins 33, and one end of each fourth touch lead 8 is connected to a second touch channel 12, and the other end is connected to a second touch pin 33.

[0304] When the display panel 100 includes a plurality of second touch leads 4 and a plurality of fourth touch leads 8 , the same second touch channel 12 is connected to the same second touch pin 33 via a second touch lead 4 and a fourth touch lead 8 , respectively.

[0305] The second touch pin 33 or the second pin 6 that does not transmit a touch signal can be used as a virtual pin 37, which is not connected to any signal line, and can also be connected to other signal lines as needed, thereby increasing the design flexibility of the display panel 100. The specific connected signal is designed accordingly according to actual needs, which is only used as an exemplary description of possible implementation methods and is not intended to limit the specific implementation methods of the present disclosure.

[0306] In some other examples, such as Figure 7 As shown, the second touch pin 33 is configured to be not connected to the touch signal line. The second pin 6 is configured to receive the second touch signal and transmit the second touch signal to the touch structure 1 through the third touch lead 5.

[0307] With such a design, it is not necessary to reserve a part of the N rows of first pins 3 in the first binding area B1 as the second touch pins 33, and the number of first pins 3 in the first binding area B1 can be less, so that the intervals between adjacent first pins 3 along the row direction are increased, so that when the signal line (for example, the first touch lead 2) in the display panel 100 passes through the interval between adjacent first pins 3 and is connected to the corresponding first pin 3 (for example, the first touch pin 31), the line width of the signal located in the interval between adjacent first pins 3 can be larger, avoiding the problem of easy breakage of the signal line due to the narrow line width of the signal line, and increasing the signal transmission reliability of the signal line. In addition, when the line width of the signal line located in the interval between adjacent first pins 3 is increased, the line resistance of the signal line can also be reduced, which is conducive to reducing the power consumption of the display panel 100.

[0308] At the same time, a part of the N rows of first pins 3 in the first binding area B1 can be reserved as the second touch pins 33, and this part of the second touch pins 33 may not be connected to any signal line in the display panel 100, and may be connected to other signal lines except the touch signal line as needed, thereby increasing the design flexibility of the display panel 100. The specific connected signals are designed accordingly according to actual needs, which is only used as an exemplary description of possible implementation methods, and is not used as a limitation on the specific implementation methods of the present disclosure.

[0309] For example, Figure 4 and Figure 6 As shown, the display panel 100 includes a second binding area B2(A) located at one end of the first binding area B1 close to the first frame area K1, and a second binding area B2(B) located at one end of the first binding area B1 close to the second frame area K2.

[0310] Exemplarily, the plurality of third touch leads 5 are divided into two groups, passing through the first frame area K1 and the second frame area K2 respectively, and extending to the second binding area B2 (A) and the second binding area B2 (B), respectively. The number of the two groups of third touch leads 5 is the same or approximately the same. In this way, the number of wirings of the plurality of third touch leads 5 in the first frame area K1 and the second frame area K2 is the same or approximately the same, which is conducive to ensuring that the non-display area of ​​the display surface of the display panel 100 is symmetrically and evenly distributed on both sides of the display area AA, thereby ensuring the aesthetic appearance and picture display effect of the display panel 100.

[0311] Exemplarily, the dimension of the second lead 6 in its extension direction is greater than or equal to 100 μm.

[0312] Exemplarily, the dimension of the second lead 6 in a direction perpendicular to its extension is greater than or equal to 15 μm.

[0313] Exemplarily, the distance between two adjacent second pins 6 is greater than or equal to 15 μm.

[0314] It should be noted that the outer dimensions and spacing of the second pins 6 can be adaptively designed according to changes in the size of the display panel 100, the size of the first binding area B1, the number of second pins 6, etc. This is only used as an exemplary description and not as a limitation on the specific implementation of the present disclosure.

[0315] Accordingly, in some embodiments, the touch control and display driver integrated chip 200 further includes two second output areas S2, respectively located at the left end and the right end of the touch control and display driver integrated chip 200. The touch control and display driver integrated chip 200 further includes: a plurality of second connection blocks 8, divided into two groups and respectively disposed in the two second output areas S2.

[0316] The second connection block 8 is configured to output a second touch signal, or configured not to output a touch signal.

[0317] When the touch and display driver integrated chip 200 further includes a plurality of second touch connection blocks 73 and a plurality of second connection blocks 8 , at least one of the second touch connection blocks 73 and the second connection blocks 8 is configured to output a second touch signal.

[0318] In some examples, the second touch connection block 73 is configured to output a second touch signal, and the second connection block 8 is configured to output a second touch signal.

[0319] In this case, the two groups of second connection blocks 8 are respectively connected to the two groups of second touch connection blocks 73. For example, each second touch connection block 73 is correspondingly connected to one second connection block 8 via one second connection line. It can be understood that, in this case, the number of a group of second touch connection blocks 73 and a group of second connection blocks 8 that are connected correspondingly is the same.

[0320] With such a design, the second touch signal is output through the second touch connection block 73 and the second connection block 8 at the same time, thereby increasing the output stability of the second touch signal. For example, when either of the second touch connection block 73 and the second connection block 8 cannot output the signal normally, the other one can still output the second touch signal, thereby ensuring the output stability of the second touch signal.

[0321] The specific corresponding connection method of the corresponding group of second touch connection blocks 73 and the corresponding group of second connection blocks 8 will be described later and will not be introduced here.

[0322] In some other examples, the second touch connection block 73 is configured to output a second touch signal, and the second connection block 8 is configured not to output a touch signal.

[0323] In this case, the second connection block 8 can also be configured to output other signal lines as required. The corresponding design is made according to actual needs, which is only an exemplary description of possible implementations and is not intended to limit the specific implementations of the present disclosure.

[0324] In some other examples, the second touch connection block 73 is configured not to output a touch signal, and the second connection block 8 is configured to output a second touch signal.

[0325] In this case, the second touch connection block 73 may not be included in the plurality of first connection blocks 7 in the first output area S1. Thus, compared with the case of including a plurality of second touch connection blocks 73, the number of first connection blocks 7 in the first output area S1 is reduced, and the spacing between adjacent first connection blocks 7 is larger, which is conducive to heat dissipation. At the same time, the number of first connection blocks 7 in the first output area S1 is reduced, so that the outer dimensions of a single first connection block 7 can also be increased accordingly, thereby increasing the connection area between the first connection block 7 and the first pin 3 in the display panel 100, thereby improving the connection stability.

[0326] In some embodiments, in the display panel 100, as Figure 4 , Figure 7 , Figure 8 and Fig. 9 As shown, the touch structure 1 includes P first touch channels 11 arranged in parallel and at intervals along the second direction Y, P≥3, and each first touch channel 11 extends along the first direction X. Along the direction from the third frame area K3 to the fourth frame area K4, the P first touch channels 11 are numbered in sequence as the first touch channel 11(1), the first touch channel 11(2), ..., the first touch channel 11(P).

[0327] In some embodiments, the display panel 100 includes a plurality of first touch leads 2 , the number of which is P, and which are respectively connected to P first touch channels 11 .

[0328] Exemplarily, one end of each first touch lead 2 is connected to a first touch channel 11 , and the other end is connected to one or a column of first touch pins 31 .

[0329] According to the numbering of the first touch channels 11 corresponding to the first touch leads 2, the P first touch leads 2 are numbered as the first touch lead 2(1), the first touch lead 2(2), ..., the first touch lead 2(P) in sequence. According to the numbering of the first touch channels 11 corresponding to the first touch pins 31, the P or P columns of first touch pins 31 are numbered as the first touch pin 31(1), the first touch pin 31(2), ..., the first touch pin 31(P) in sequence.

[0330] It should be noted that, when the first touch pins 31 in the above-mentioned P column are numbered sequentially as the first touch pin 31(1), the first touch pin 31(2), ..., the first touch pin 31(P), the numbers of the first touch pins 31 in the same column are the same, and the numbers of the first touch pins 31 in different columns are different.

[0331] The first touch channel 11, the first touch lead 2 and the first touch pin 31 are connected according to the corresponding numbers, for example, the first touch channel 11 (T), the first touch lead 2 (T) and the first touch pin 31 (T) are connected in sequence, 1≤T≤P. The first touch pin 31 (T) can be a first touch pin 31 (T) or a row of first touch pins 31 (T) with the same number.

[0332] Exemplarily, when multiple first touch pins 31 (T) in the same column have the same number, the multiple first touch pins 31 (T) in the same column are electrically connected, and when connected to any one of the first touch pins 31 (T), all the multiple first touch pins 31 (T) with the same number in this column can be electrically connected.

[0333] The touch structure 1 includes 40 first touch channels 11. Along the direction from the third frame area K3 to the fourth frame area K4, the 40 first touch channels 11 are numbered as first touch channel 11 (1), first touch channel 11 (2), ..., first touch channel 11 (40).

[0334] In the case where the touch structure 1 includes 40 first touch channels 11, and one end of each first touch lead 2 is connected to a first touch channel 11, and the other end is connected to a first touch pin 31, the display panel 100 includes 40 first touch leads 2 and 40 first touch pins 31. According to the numbering of the first touch channels 11 correspondingly connected to the first touch leads 2, the 40 first touch leads 2 are numbered as first touch lead 2 (1), first touch lead 2 (2), ..., first touch lead 2 (40) in sequence. According to the numbering of the first touch channels 11 correspondingly connected to the first touch pins 31, the 40 first touch pins 31 are numbered as first touch pin 31 (1), first touch pin 31 (2), ..., first touch pin 31 (40) in sequence.

[0335] When the touch structure 1 includes 40 first touch channels 11, and one end of each first touch lead 2 is connected to one first touch channel 11, and the other end is connected to a column of first touch pins 31, the display panel 100 includes 40 first touch leads 2 and 120 first touch pins 31. According to the numbering of the first touch channels 11 corresponding to the first touch pins 31, the 40 columns of first touch pins 31 are numbered as first touch pin 31 (1), first touch pin 31 (2), ..., first touch pin 31 (40) in sequence, wherein the first touch pins 31 in each column have the same numbering, and the first touch leads 2 corresponding to the column of first touch pins 31 with the same numbering are all connected to the column of first touch pins 31.

[0336] It should be noted that the first touch lead 2 corresponding to a column of first touch pins 31 with the same number is connected to all the first touch pins 31 in this column. It can be that multiple first touch pins 31 with the same number in the same column are electrically connected. When the first touch lead 2 is connected to any one of the first touch pins 31, it can be electrically connected to all the first touch pins 31 with the same number in this column; it can also be that the first touch lead 2 is electrically connected to multiple first touch pins 31 with the same number in this column. It can be understood that in order to ensure the normal transmission of the touch signal, the corresponding touch pin (such as the first touch pin 31) and the touch lead CK (such as the first touch lead 2) can be connected to achieve signal transmission. This is only an exemplary description and not a limitation of the present disclosure.

[0337] In some embodiments, in the display panel 100, as shown in FIG. Figure 4 and Figure 7 As shown, the first touch lead 2 (1) to the first touch lead 2 (Px) are led out from the first border area K1, 1≤x<x+1≤P, and in the area adjacent to the first binding area B1 close to the display area AA side, along the direction from the first border area K1 to the reference center line C, the numbers of the first touch leads 2 become larger in sequence.

[0338] The first touch lead 2 (P-x+1) to the first touch lead 2 (P) are led out from the second border area K2, and in the area adjacent to the first binding area B1 close to the display area AA, the numbers of the first touch leads 2 increase successively along the direction from the second border area K2 to the reference center line C.

[0339] For example, Figure 7 , Figure 8 and Fig. 9 As shown, the display panel 100 includes 40 first touch leads 2 as an example. Among the 40 first touch leads 2, the first touch leads 2(1) to the first touch leads 2(20) are divided into a group and led out from the first frame area K1 and extend to the first pin area J1, and are connected to the first touch pins 31(1) to the first touch pins 31(20) correspondingly; Figure 7 and Figure 8 In the direction where the left side points to the right side, the first touch lead 2 ( 1 ) to the first touch lead 2 ( 20 ) are arranged in sequence, for example, in the order of numbers.

[0340] The first touch lead 2 (21) to the first touch lead 2 (40) are divided into a group and led out from the second frame area K2 and extend to the third pin area J3, and are connected to the first touch pin 31 (21) to the first touch pin 31 (40) correspondingly; Figure 7 and Fig. 9The right side in the figure points to the left side, and the first touch lead 2 (21) to the first touch lead 2 (40) are arranged in sequence, for example, in the order of numbers.

[0341] On the side of the first binding area B1 close to the display area AA, along Figure 7 and Figure 8 In the direction from the left side to the right side, the first touch lead 2(1), the first touch lead 2(2), ..., the first touch lead 2(10) are arranged in the order of increasing numbers, along Figure 7 and Fig. 9 In the direction from the right side to the left side, the first touch lead 2 (11), the first touch lead 2 (12), ..., the first touch lead 2 (20) are arranged in the order of increasing numbers.

[0342] In some other embodiments, in the display panel 100, as shown in FIG. Figure 4 , Figure 7 and Figure 8 As shown, among the first touch leads 2(1) to the first touch leads 2(P), the first touch leads 2 with odd numbers are divided into a group and led out from the first border area K1, and in the area adjacent to the first binding area B1 close to the display area AA side, the numbers of the first touch leads 2 become larger along the direction from the first border area K1 to the reference center line C.

[0343] Among the first touch leads 2(1) to the first touch leads 2(P), the first touch leads 2 with even numbers are divided into a group and led out from the second border area K2, and in the area adjacent to the first binding area B1 close to the display area AA side, the numbers of the first touch leads 2 become larger along the direction from the second border area K2 to the reference center line C.

[0344] Exemplarily, taking the display panel 100 including 40 first touch leads 2 as an example, the 40 first touch leads 2 are divided into single array and double array according to the numbers. For example, the first touch lead 2(1), the first touch lead 2(3), ..., the first touch lead 2(39) are divided into a single array, which is led out from the first border area K1 and extends to the first pin area J1, and is correspondingly connected to the first touch pin 31(1), the first touch pin 31(3), ..., the first touch pin 31(39).

[0345] The first touch lead 2(2), the first touch lead 2(4), ..., the first touch lead 2(40) are divided into a double array, led out from the second border area K2, and extended to the third pin area J3, and are correspondingly connected to the first touch pin 31(2), the first touch pin 31(4), ..., the first touch pin 31(40).

[0346] On the side of the first binding area B1 close to the display area AA, along Figure 7In the direction from the left side to the right side, the first touch lead 2 (1), the first touch lead 2 (3), ..., the first touch lead 2 (39) are arranged in the order of increasing numbers, along Figure 7 In the direction from the right side to the left side, the first touch lead 2 (2), the first touch lead 2 (4), ..., the first touch lead 2 (40) are arranged in the order of increasing numbers.

[0347] It is understandable that, when the plurality of first touch leads 2 are divided into two groups and respectively led out from the first frame area K1 and the second frame area K2, and extended to the first pin area J1 and the third pin area J3, the grouping leading-out method of the plurality of first touch leads 2 includes but is not limited to the above situation. And the plurality of first touch leads 2 can also all be led out from the first frame area K1 and extend to the first pin area J1, or led out from the second frame area K2 and extend to the third pin area J3. The corresponding design is made according to the actual needs, which is only used as an example of possible implementation, and is not used as a limitation on the specific implementation of the present disclosure.

[0348] The following is an example in which the display panel 100 includes 40 first touch leads 2, the first touch leads 2(1) to the first touch leads 2(20) are divided into a group, led out from the first frame area K1, and extended to the first pin area J1, and the first touch leads 2(21) to the first touch leads 2(40) are divided into a group, led out from the second frame area K2, and extended to the third pin area J3.

[0349] In some embodiments, in the display panel 100, as Figure 4 , Figure 6 and Figure 7 As shown, the number of first touch pins 31 is P, which are respectively connected to P first touch channels 11. The P first touch pins 31 are numbered first touch pin 31 (1), first touch pin 31 (2), ..., first touch pin 31 (P) in sequence. Each column of first touch pins 31 includes N first touch pins 31 with consecutive numbers.

[0350] The first touch pins 31(1) to the first touch pins 31(Px) are arranged in the first pin area J1, 1≤x<x+1≤P, and along the direction from the first border area K1 to the reference center line C, the numbers of the first touch pins 31 in each row increase successively and are an arithmetic progression with a difference of N.

[0351] The first touch pins 31 (P-x+1) to the first touch pins 31 (P) are arranged in the third pin area J3, and along the direction from the second frame area K2 to the reference center line C, the numbers of the first touch pins 31 in each row increase in sequence and are an arithmetic progression, and the difference is N. The reference center line C is the center line of the display panel 100 along the second direction Y.

[0352] The P first touch leads 2 are divided into a plurality of subgroups Z1, each of which includes N adjacent first touch leads 2. A column of first touch pins 31 includes N first touch pins 31, and the N first touch leads 2 of each subgroup Z1 are respectively connected to the N first touch pins 31 of a column, and the N first touch pins 31 of each column are numbered consecutively.

[0353] It should be noted that, a column of first touch pins 31 includes at least one first touch pin 31, and the consecutive numbering of the N first touch pins 31 in each column means that, when a column of first touch pins 31 includes multiple (two or more) first touch pins 31, the numbers of the multiple first touch pins 31 in the same column are consecutive, but the multiple first touch pins 31 with consecutive numbers in the same column may be arranged in sequence along the column direction in the order of the numbers, or may not be arranged in the order of the numbers.

[0354] For example, Figures 8 to 15 As shown, the plurality of first touch pins 31 are arranged in three rows, the plurality of first touch pins 31 in each row are sequentially arranged along the first direction X, and each column of first touch pins 31 includes at least one first touch pin 31 .

[0355] Taking the display panel 100 as an example in which the number of the first touch pins 31 is 40, according to the numbering of the first touch channels 11 corresponding to the first touch leads 2, the 40 first touch pins 31 are numbered in sequence as the first touch pin 31 (1), the first touch pin 31 (2), ..., the first touch pin 31 (40).

[0356] The first touch pins 31(1) to 31(20) are arranged in the first pin area J1. The first touch pins 31 in the same row are numbered along the Figure 8 , Fig.10 , Fig.12 and Fig.14 The numbers increase from the left to the right.

[0357] The first touch pins 31 (21) to the first touch pins 31 (40) are arranged in the third pin area J3. The first touch pins 31 in the same row are numbered along the Fig. 9 , Fig.11 , Fig.13 and Fig.15 The numbers in the figure decrease from left to right.

[0358] In some examples, the plurality of first touch pins 31 are arranged in three rows, such as Figure 8 , Fig.10 , Fig.12 and Fig.14As shown, in the three rows of first touch pins 31 in the first pin area J1, the numbers of the first touch pins 31 in the same column are continuous, and the numbers of the first touch pins 31 in the same row increase in sequence along the first direction X and in the direction pointing to the reference center line C, and are an arithmetic progression with a difference of 3; Fig. 9 , Fig.11 , Fig.13 and Fig.15 As shown, in the three rows of first touch pins 31 in the third pin area J3, the numbers of the first touch pins 31 in the same column are continuous, and the numbers of the first touch pins 31 in the same row decrease along the first direction X and pointing to the reference center line C, and are an arithmetic progression with a difference of 3.

[0359] along Figure 8 , Fig.10 , Fig.12 and Fig.14 The three first touch pins 31 in the first column of the first touch pins 31 in the direction from the left side to the right side are respectively the first touch pin 31(1), the first touch pin 31(2) and the first touch pin 31(3). The arrangement order of the first touch pin 31(1), the first touch pin 31(2) and the first touch pin 31(3) along the column direction can be increasing in sequence according to the numbering order, decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

[0361] The first touch pins 31 in the same row as the first touch pin 31(1) are, from left to right, the first touch pin 31(1), the first touch pin 31(4), ..., the first touch pin 31(19). The first touch pins 31 in the same row as the first touch pin 31(2) are, from left to right, the first touch pin 31(2), the first touch pin 31(5), ..., the first touch pin 31(20). The first touch pins 31 in the same row as the first touch pin 31(3) are, from left to right, the first touch pin 31(3), the first touch pin 31(6), ..., the first touch pin 31(18).

[0363] The multiple first touch pins 31 in the first pin area J1 and the multiple first touch pins 31 in the third pin area J3 may be arranged symmetrically about the second direction Y. In this case, the first touch pin 31(1) and the first touch pin 31(21) are located in the same row, the first touch pin 31(2) and the first touch pin 31(22) are located in the same row, and the first touch pin 31(3) and the first touch pin 31(23) are located in the same row. The symmetrical arrangement mentioned here means that the arrangement path of the multiple first touch pins 31 in the first pin area J1 from small to large according to the numbering, and the arrangement path of the multiple first touch pins 31 in the third pin area J3 from small to large according to the numbering are symmetrical about the second direction Y.

[0364] Figures 8 to 15 In the embodiment, the specific arrangement of the first touch pins 31 arranged in three rows is only used as an exemplary description and is not intended to limit the specific implementation manner of the present disclosure.

[0365] In some other examples, the plurality of first touch pins 31 are arranged in four rows, such as Fig.16 As shown, in the four rows of first touch pins 31 in the first pin area J1, the numbers of the first touch pins 31 in the same column are continuous, and the numbers of the first touch pins 31 in the same row increase in sequence along the first direction X and in the direction pointing to the reference center line C, and are an arithmetic progression with a difference of 4; Fig.17 As shown, in the four rows of first touch pins 31 in the third pin area J3, the numbers of the first touch pins 31 in the same column are continuous, and the numbers of the first touch pins 31 in the same row increase successively along the first direction X and pointing to the reference center line C, and are an arithmetic progression with a difference of 4.

[0366] along Fig.16The four first touch pins 31 in the first column of the first touch pins 31 in the direction from the left side to the right side are respectively the first touch pin 31(1), the first touch pin 31(2), the first touch pin 31(3) and the first touch pin 31(4). The arrangement order of the first touch pin 31(1), the first touch pin 31(2), the first touch pin 31(3) and the first touch pin 31(4) along the column direction can be increasing in the order of numbers, decreasing in the order of numbers, or not arranged in the order of numbers.

[0367] along Fig.17 The four first touch pins 31 in the first column of the first touch pins 31 in the direction from the right side to the left side are respectively the first touch pin 31 (21), the first touch pin 31 (22), the first touch pin 31 (23) and the first touch pin 31 (24). The arrangement order of the first touch pin 31 (21), the first touch pin 31 (22), the first touch pin 31 (23) and the first touch pin 31 (24) along the column direction can be increasing in sequence according to the numbering order, decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

The first touch pins 31 in the same row as the first touch pin 31(2) are, from left to right, the first touch pin 31(2), the first touch pin 31(6), ..., the first touch pin 31(18). The first touch pins 31 in the same row as the first touch pin 31(3) are, from left to right, the first touch pin 31(3), the first touch pin 31(7), ..., the first touch pin 31(19). The first touch pins 31 in the same row as the first touch pin 31(4) are, from left to right, the first touch pin 31(4), the first touch pin 31(8), ..., the first touch pin 31(20).

[0370] The plurality of first touch pins 31 in the first pin area J1 and the plurality of first touch pins 31 in the third pin area J3 may be arranged symmetrically about the second direction Y. In this case, the first touch pin 31(1) and the first touch pin 31(21) are located in the same row, the first touch pin 31(2) and the first touch pin 31(22) are located in the same row, the first touch pin 31(3) and the first touch pin 31(23) are located in the same row, and the first touch pin 31(4) and the first touch pin 31(24) are located in the same row.

[0371] For example, Fig.16 and Fig.17 As shown, a part of the plurality of second touch pins 33 is configured to be connected to the second touch lead 4, and another part can be configured not to be connected to the touch signal line (for example, the second touch lead 4 and the fourth touch lead 8), not to transmit the touch signal, and to serve as a virtual pin 37. At least a part of the second touch pins 33 serving as virtual pins 37 (not connected to the touch signal line, not transmitting the touch signal) can also be connected to other signals as needed. The specific connected signals are designed accordingly according to actual needs, and are only used as an exemplary description of possible implementations, and are not intended to be a limitation on the specific implementations of the present disclosure.

[0372] Fig.16 and Fig.17 In the embodiment, the specific arrangement of the first touch pins 31 arranged in four rows is only used as an exemplary description and is not intended to limit the specific implementation manner of the present disclosure.

The first touch pins 31 in the same row as the first touch pin 31 (23) are, from right to left, the first touch pin 31 (23), the first touch pin 31 (28), the first touch pin 31 (33), and the first touch pin 31 (38). The first touch pins 31 in the same row as the first touch pin 31 (24) are, from right to left, the first touch pin 31 (24), the first touch pin 31 (29), the first touch pin 31 (34), and the first touch pin 31 (39).

[0378] The plurality of first touch pins 31 in the first pin area J1 and the plurality of first touch pins 31 in the third pin area J3 may be arranged symmetrically about the second direction Y. In this case, the first touch pin 31(1) and the first touch pin 31(21) are located in the same row, the first touch pin 31(2) and the first touch pin 31(22) are located in the same row, the first touch pin 31(3) and the first touch pin 31(23) are located in the same row, the first touch pin 31(4) and the first touch pin 31(24) are located in the same row, and the first touch pin 31(5) and the first touch pin 31(25) are located in the same row. The symmetrical arrangement mentioned here means that the arrangement path of the plurality of first touch pins 31 in the first pin area J1 from small to large according to the numbering, and the arrangement path of the plurality of first touch pins 31 in the third pin area J3 from small to large according to the numbering are symmetrical about the second direction Y.

[0379] Fig.18 and Fig.19 In the embodiment, the specific arrangement of the first touch pins 31 in five rows is only used as an exemplary description and is not intended to limit the specific implementation manner of the present disclosure.

[0380] It should be noted that, in the display panel 100, the multiple first touch pins 31 can also be arranged in 2 rows, 6 rows, 7 rows or more rows. The specific number and arrangement of the first touch pins 31 are designed accordingly according to actual needs. It can be understood that the arrangement of the multiple first touch pins 31 includes but is not limited to the above examples, which are only used as illustrative descriptions here and not as a limitation on the specific embodiments of the present disclosure.

[0381] In some embodiments, Figures 8 to 19 As shown, among the N rows of first touch pins 31 arranged in the first binding area B1 of the display panel 100, when the numbers of multiple first touch pins 31 in the same column are different, a part of the multiple first touch leads 2 passes through the gaps between the first pins 3 arranged adjacently along the first direction X and is connected to the corresponding first touch pins 31, and the line width of the part of the first touch lead 2 located in the gap is smaller than the line width of the part located outside the first binding area B1.

[0382] For example, Figures 6 to 19 As shown, among the 40 first touch leads 2 included in the display panel 100, the first touch leads 2(1) to the first touch leads 2(20) are divided into a group, led out from the first frame area K1, and extended to the first pin area J1, and are correspondingly connected to the first touch pins 31(1) to the first touch pins 31(20); the first touch leads 2(21) to the first touch leads 2(40) are divided into a group, led out from the second frame area K2, and extended to the third pin area J3, and are correspondingly connected to the first touch pins 31(21) to the first touch pins 31(40).

[0383] The interval between two adjacent first pins 3 (for example, first touch pins 31) along the first direction X is 10 μm to 15 μm. Figures 8 to 19 As shown, at least a portion of the multiple first touch leads 2 pass through two adjacent first touch pins 31 to be connected to the corresponding first touch pins 31, and the line width of the portion of the first touch lead 2 located between the two adjacent first touch pins 31 is, for example, 2μm to 3μm, and the line width of the portion of the first touch lead 2 located outside the first pin area J1 and the third pin area J3 is greater than or equal to 3μm.

[0384] Accordingly, in some embodiments, in the touch control and display driver integrated chip 200, for example Figure 5 , Figures 20 to 31 As shown, the number of the plurality of first touch connection blocks 71 is P, where P≥3, and they are sequentially numbered as first touch connection block 71(1), first touch connection block 71(2), ..., first touch connection block 71(P), and are configured to respectively output first touch signals to the P first touch channels 11 of the display panel 100. Each column of the first touch connection blocks 71 includes N first touch connection blocks 71 with consecutive numbers.

[0385] The first touch connection blocks 71(1) to the first touch connection blocks 71(Px) are arranged in the first connection area L1, 1≤x<x+1≤P, and along the direction from the right end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the first touch connection blocks 71 in each row increase successively and are an arithmetic progression with a difference of N.

[0386] The first touch connection blocks 71 (P-x+1) to the first touch connection blocks 71 (P) are arranged in the third connection area L3, and along the direction from the left end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the first touch connection blocks 71 in each row increase successively and are an arithmetic progression with a difference of N.

[0387] It should be noted that a column of first touch connection blocks 71 includes at least one first touch connection block 71, and the consecutive numbering of the N first touch connection blocks 71 in each column means that, when a column of first touch connection blocks 71 includes multiple (two or more) first touch connection blocks 71, the numbers of the multiple first touch connection blocks 71 in the same column are consecutive, but the multiple first touch connection blocks 71 with consecutive numbers in the same column can be arranged in sequence along the column direction in the order of the numbers, or not in the order of the numbers.

[0388] Taking the example that the number of first touch connection blocks 71 included in the touch and display driver integrated chip 200 is 40, when the touch and display driver integrated chip 200 is connected correspondingly to the display panel 100, the multiple first touch pins 31 included in the display panel 100 are respectively connected to the multiple first touch connection blocks 71 of the touch and display driver integrated chip 200.

[0389] For example, Figures 20 to 27 As shown, the plurality of first touch connection blocks 71 are arranged in three rows, the plurality of first touch connection blocks 71 in each row are sequentially arranged along the first direction X, and each column of first touch connection blocks 71 includes at least one first touch connection block 71 .

[0390] Taking the number of the first touch connection blocks 71 included in the touch and display driver integrated chip 200 as 40 as an example, when the touch and display driver integrated chip 200 is connected to the display panel 100, the multiple first touch pins 31 included in the display panel 100 are respectively connected to the multiple first touch connection blocks 71 of the touch and display driver integrated chip 200. According to the numbering of the first touch pins 31 connected to the first touch connection blocks 71, the 40 first touch connection blocks 71 are numbered in sequence as the first touch connection block 71 (1), the first touch connection block 71 (2), ..., the first touch connection block 71 (40).

[0391] The first touch connection blocks 71(1) to the first touch connection blocks 71(20) are arranged in the first connection area L1. The first touch connection blocks 71 in the same row are numbered along the Fig. 20 , Fig. 22 , Fig.24 and Fig.26 The numbers in the figure increase as they point from the right side to the left side.

The first touch connection blocks 71 in the same row are numbered along Fig.21 , Fig.23 , Fig.25 and Fig. 27 The numbers in the figure decrease as they point from the right side to the left side.

[0393] In some examples, the plurality of first touch connection blocks 71 are arranged in three rows, such as Fig. 20 , Fig. 22 , Fig.24 and Fig.26 As shown, among the three rows of first touch connection blocks 71 in the first connection area L1, the first touch connection blocks 71 in the same column are numbered continuously, and the numbers of the first touch connection blocks 71 in the same row increase in sequence from the right end to the left end of the touch and display driver integrated chip 200, and are an arithmetic progression with a difference of 3; Fig.21 , Fig.23 , Fig.25 and Fig. 27 As shown, in the three rows of first touch connection blocks 71 in the third connection area L3, the numbers of the first touch connection blocks 71 in the same column are continuous, and the numbers of the first touch connection blocks 71 in the same row increase successively from the left end to the right end of the touch and display driver integrated chip 200, and are an arithmetic progression with a difference of 3.

The arrangement order of the first touch connection block 71(1), the first touch connection block 71(2) and the first touch connection block 71(3) along the column direction can be increasing in sequence according to the numbering order, decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

[0398] The multiple first touch connection blocks 71 in the first connection area L1 and the multiple first touch connection blocks 71 in the third connection area L3 may be arranged symmetrically about the second direction Y. In this case, the first touch connection block 71(1) and the first touch connection block 71(21) are located in the same row, the first touch connection block 71(2) and the first touch connection block 71(22) are located in the same row, and the first touch connection block 71(3) and the first touch connection block 71(23) are located in the same row.

[0404] The first touch connection blocks 71 in the same row as the first touch connection block 71 (21) are, from left to right, the first touch connection block 71 (21), the first touch connection block 71 (25), ..., the first touch connection block 71 (37).

The symmetrical arrangement mentioned here means that the arrangement path of the plurality of first touch connection blocks 71 in the first connection area L1 from small to large in number and the arrangement path of the plurality of first touch connection blocks 71 in the third connection area L3 from small to large in number are symmetrical with respect to the second direction Y.

[0413] Fig.30 and Fig.31 In the embodiment, the specific arrangement of the first touch connection blocks 71 arranged in five rows is only used as an exemplary description and is not intended to limit the specific implementation manner of the present disclosure.

[0414] It should be noted that, in the touch and display driver integrated chip 200, the multiple first touch connection blocks 71 can also be arranged in 2 rows, 6 rows, 7 rows or more rows. The specific number and arrangement of the first touch connection blocks 71 are designed accordingly according to actual needs. It can be understood that the arrangement of the multiple first touch connection blocks 71 includes but is not limited to the above examples, which are only used as illustrative descriptions here and not as a limitation on the specific embodiments of the present disclosure.

[0415] In some embodiments, in the display panel 100, as Figure 4 , Fig.32 and Fig.33 As shown, the number of the plurality of first touch pins 31 is N×P, where P≥3, and they are arranged in N rows and P columns. The P first touch pins 31 in each row are numbered first touch pin 31(1), first touch pin 31(2), ..., first touch pin 31(P) in sequence; the N first touch pins 31 in each column are numbered the same, and the first touch pins 31 in P columns are connected to P first touch leads 2 respectively.

[0416] The first touch pins 31 ( 1 ) to the first touch pins 31 (Px) are arranged in the first pin area J1 , 1≤x<x+1≤P, and along the direction from the first border area K1 to the reference center line C, the numbers of the first touch pins 31 increase successively and are continuous.

[0417] The first touch pins 31 (P-x+1) to the first touch pins 31 (P) are arranged in the third pin area J3, and along the direction from the second frame area K2 to the reference center line C, the numbers of the first touch pins 31 increase successively and are continuous.

[0418] For example, Fig.32 and Fig.33 As shown, among the N rows of first touch pins 31 arranged in the first binding area B1 of the display panel 100, when the multiple first touch pins 31 in the same column have the same number, each first touch lead 2 overlaps with a corresponding column of first touch pins 31, and the line width of the portion of the first touch lead 2 located in the first binding area B1 is equal to the line width of the portion located outside the first binding area B1.

[0419] For example, Fig.32 and Fig.33 As shown, the line width of the first touch-control leads 2 is greater than or equal to 10 μm, and the interval between two adjacent first touch-control leads 2 is greater than or equal to 10 μm.

[0420] With such a design, when each touch lead CK (for example, the first touch lead 2) is connected to its corresponding first touch pin 31, the first touch lead 2 does not need to pass through the gap area between adjacent first touch pins 31. Therefore, the line width of the portion where the first touch lead 2 is connected to the corresponding first touch pin 31 can be larger. Accordingly, the line resistance of the first touch lead 2 is smaller, which is beneficial to reducing the power consumption of the display panel 100. At the same time, the increase in the line width of the first touch lead 2 also increases the reliability of the first touch lead 2, avoiding the problem of the first touch lead 2 being easily broken due to the first touch lead 2 having a too small line width.

[0421] It should be noted that, when the numbers of the first touch pins 31 in the same column are the same, Fig.32 and Fig.33 As shown, the same column may include a plurality of first touch pins 31 with the same individual number, such as Fig.34 and Fig.35 As shown, the same column may also include a first touch pin 31 extending along the column direction.

[0422] For example, Fig.32 and Fig.33 As shown, the display panel 100 includes 40 first touch leads 2 and 120 first touch pins 31. The 120 first touch pins 31 are arranged in 3 rows and 40 columns. Each column of first touch pins 31 includes at least one first touch pin 31 with the same number. In the 3 rows of first touch pins 31 in the first pin area J1, the numbers of the multiple first touch pins 31 in each row are in the order of Fig.32In the direction from the left to the right in the third pin area J3, the numbers of the first touch pins 31 in each row are as follows: Fig.33 The numbers in the figure increase as they point from the right side to the left side.

[0423] In this case, in the three rows of first touch pins 31 in the first pin area J1, the first touch pins 31 in the same row are numbered continuously; in the three rows of first touch pins 31 in the third pin area J3, the first touch pins 31 in the same row are numbered continuously.

[0424] It should be noted that, when the multiple first touch leads 2 are divided into a single array and a double array and are respectively led out to the first pin area J1 and the third pin area J3, in the three rows of first touch pins 31 in the first pin area J1, the first touch pins 31 in each row are numbered as an arithmetic progression with a difference of 2; in the three rows of first touch pins 31 in the third pin area J3, the first touch pins 31 in each row are numbered as an arithmetic progression with a difference of 2.

[0425] Accordingly, in some embodiments, in the touch and display driver integrated chip 200, the number of the plurality of first touch connection blocks 71 is N×P, P≥3, and they are arranged in N rows and P columns. The P first touch connection blocks 71 in each row are numbered first touch connection block 71(1), first touch connection block 71(2), ..., first touch connection block 71(P) in sequence. The N first touch connection blocks 71 in each column are numbered the same, and the P columns of first touch connection blocks 71 are configured to output first touch signals to the P first touch channels 11 of the display panel 100, respectively.

[0426] The first touch connection blocks 71(1) to the first touch connection blocks 71(Px) are arranged in the first connection area L1, 1≤x<x+1≤P, and along the direction from the right end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the first touch connection blocks 71 increase successively and the numbers are continuous.

[0427] The first touch connection block 71 (P-x+1) to the first touch connection block 71 (P) are arranged in the third connection area L3, and along the direction from the left end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the first touch connection blocks 71 become larger and the numbers are continuous.

[0428] Exemplarily, the touch and display driver integrated chip 200 includes 120 first touch connection blocks 71, and the 120 first touch connection blocks 71 are arranged in 3 rows and 40 columns, and each column of first touch connection blocks 71 includes 3 first touch connection blocks 71 with the same number. In the 3 rows of first touch connection blocks 71 in the first connection area L1, the numbers of the multiple first touch connection blocks 71 in the same row increase in sequence along the first direction X and along the direction from the first frame area K1 to the reference center line C; in the 3 rows of first touch connection blocks 71 in the third connection area L3, the numbers of the multiple first touch connection blocks 71 in the same row increase in sequence along the direction from the left end to the right end of the touch and display driver integrated chip 200.

[0429] In this case, among the three rows of first touch connection blocks 71 in the first connection area L1, the first touch connection blocks 71 in the same row are numbered continuously; among the three rows of first touch connection blocks 71 in the third connection area L3, the first touch connection blocks 71 in the same row are numbered continuously.

[0430] The multiple first touch connection blocks 71 with the same number in the same column are electrically insulated from each other. The multiple first touch connection blocks 71 with the same number in the same column are electrically insulated from each other, which means that when connecting to any one of the first touch connection blocks 71 with the same number in a column, it will not be electrically connected to the other first touch connection blocks 71 with the same number in the column.

[0431] It should be noted that, when the display panel 100 connected to the touch and display driver integrated chip 200 includes a plurality of first touch leads 2 which are divided into a single array and a double array and are respectively led out to the first pin area J1 and the third pin area J3, among the three rows of first touch connection blocks 71 in the first connection area L1, the first touch connection blocks 71 in the same row are numbered as an arithmetic progression with a difference of 2; among the three rows of first touch connection blocks 71 in the third connection area L3, the first touch connection blocks 71 in the same row are numbered as an arithmetic progression with a difference of 2.

[0432] In some embodiments, in the display panel 100, as Figure 2 , Figure 6 and Figure 7 As shown, the touch structure 1 includes Q second touch channels 12 arranged in parallel and at intervals along a first direction X, Q ≥ 3, and each second touch channel 12 is extended along a second direction Y. Along the direction from the first frame area K1 to the second frame area K2, the Q second touch channels 12 are numbered in sequence as second touch channel 12 (1), second touch channel 12 (2), ..., second touch channel 12 (Q).

[0433] In some embodiments, the display panel 100 includes a plurality of second touch leads 4, the number of which is Q, and each of which is connected to the Q second touch channels 12. The Q second touch leads 4 are numbered as second touch lead 4(1), second touch lead 4(2), ..., second touch lead 4(Q) in sequence according to the numbering of the second touch channels 12 corresponding to the second touch leads 4.

[0434] Exemplarily, one end of each second touch lead 4 is connected to a second touch channel 12, and the other end is connected to one or a column of second touch pins 33. According to the number of the second touch channel 12 correspondingly connected to the second touch pin 33, the Q or Q columns of second touch pins 33 are sequentially numbered as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (Q).

[0435] It should be noted that, when the second touch pins 33 in the Q column are numbered sequentially as the second touch pin 33 (1), the second touch pin 33 (2), ..., the second touch pin 33 (Q), the numbers of the second touch pins 33 in the same column are the same, and the numbers of the second touch pins 33 in different columns are different.

[0436] The second touch channel 12, the second touch lead 4 and the second touch pin 33 are connected according to the corresponding numbers. For example, the second touch channel 12(R), the second touch lead 4(R) and the second touch pin 33(R) are connected in sequence, 1≤R≤Q. The second touch pin 33(R) can be a second touch pin 33(R) or a row of second touch pins 33(R) with the same number.

[0437] Exemplarily, when multiple second touch pins 33(R) in the same column have the same number, the multiple second touch pins 33(R) in the same column are electrically connected, and when connected to any one of the second touch pins 33(R), all the second touch pins 33(R) with the same number in this column can be electrically connected.

[0438] The touch structure 1 includes 20 second touch channels 12 as an example for description. Along the direction from the first frame area K1 to the second frame area K2, the 20 second touch channels 12 are numbered as second touch channel 12 (1), second touch channel 12 (2), ..., second touch channel 12 (20) in sequence. According to the numbering of the second touch channels 12 corresponding to the second touch leads 4, the 20 second touch leads 4 are numbered as second touch leads 4 (1), second touch leads 4 (2), ..., second touch leads 4 (20) in sequence.

[0439] In the case where the touch structure 1 includes 20 second touch channels 12, and one end of each second touch lead 4 is connected to one second touch channel 12, and the other end is connected to one second touch pin 33, the display panel 100 includes 20 second touch leads 4 and 40 second touch pins 33. According to the numbering of the second touch channels 12 correspondingly connected to the second touch leads 4, the 20 second touch leads 4 are numbered as second touch lead 4 (1), second touch lead 4 (2), ..., second touch lead 4 (20) in sequence. According to the numbering of the second touch channels 12 correspondingly connected to the second touch pins 33, the 20 second touch pins 33 are numbered as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (20) in sequence.

[0440] When the touch structure 1 includes 20 second touch channels 12, and one end of each second touch lead 4 is connected to one second touch channel 12, and the other end is connected to a column of second touch pins 33, the display panel 100 includes 20 second touch leads 4 and 60 second touch pins 33. According to the numbering of the second touch channels 12 corresponding to the second touch pins 33, the 20 columns of second touch pins 33 are numbered as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (20), wherein the second touch pins 33 in each column are numbered the same, and the second touch leads 4 corresponding to the column of second touch pins 33 with the same number are all connected to the column of second touch pins 33.

[0441] It should be noted that the second touch lead 4 corresponding to a column of second touch pins 33 with the same number is connected to all the second touch pins 33 in this column. It can be that multiple second touch pins 33 with the same number in the same column are electrically connected. When the second touch lead 4 is connected to any one of the second touch pins 33, it can be electrically connected to all the second touch pins 33 with the same number in this column; it can also be that the second touch lead 4 is electrically connected to multiple second touch pins 33 with the same number in this column. It can be understood that in order to ensure the normal transmission of the touch signal, it is sufficient to connect the corresponding touch pin (such as the second touch pin 33) and the touch lead CK (such as the second touch lead 4) to achieve signal transmission. This is only an exemplary description and not a limitation of the present disclosure.

[0442] In some embodiments, in the display panel 100, as shown in FIG. Figure 2 , Figure 4 , Figure 6 and Figure 7As shown, the second touch leads 4(1) to the second touch leads 4(Qy) are led out from the fourth border area K4, 1≤y<y+1≤Q, and in the area adjacent to the first binding area B1 close to the display area AA side, along the direction from the first border area K1 to the reference center line C, the numbers of the second touch leads 4 become larger in sequence.

[0443] The second touch lead 4 (Q-y+1) to the second touch lead 4 (Q) are led out from the fourth border area K4, and in the area adjacent to the first binding area B1 close to the display area AA, the numbers of the second touch leads 4 decrease successively along the direction from the second border area K2 to the reference center line C.

[0444] For example, Figure 7 , Figure 8 and Fig. 9 As shown, the number of second touch leads 4 included in the display panel 100 is taken as an example for explanation. Among the 20 second touch leads 4, the second touch leads 4(1) to the second touch leads 4(10) are divided into a group and led out from the fourth frame area K4 and extend to the fourth pin area J4, and are connected to the second touch pins 33(1) to the second touch pins 33(10) correspondingly; along Figure 7 and Figure 8 In the direction where the left side points to the right side, the second touch leads 4 ( 1 ) to the second touch leads 4 ( 10 ) are arranged in sequence, for example, in the order of numbers.

[0445] The second touch leads 4 (11) to the second touch leads 4 (20) are divided into a group and led out from the fourth frame area K4 and extend to the fifth pin area J5, and are connected to the second touch pins 33 (11) to the second touch pins 33 (20) correspondingly; Figure 7 and Fig. 9 In the direction where the left side points to the right side, the second touch leads 4 (11) to the second touch leads 4 (20) are arranged in sequence, for example, in the order of numbers.

[0446] On the side of the first binding area B1 close to the display area AA, along Figure 7 and Figure 8 In the direction from the left side to the right side, the second touch lead 4(1), the second touch lead 4(2), ..., the second touch lead 4(10) are arranged in the order of increasing numbers, along Figure 7 and Fig. 9 In the direction from the right side to the left side, the second touch lead 4 (11), the second touch lead 4 (12), ..., the second touch lead 4 (20) are arranged in the order of increasing numbers.

[0447] In some other embodiments, in the display panel 100, as shown in FIG. Figure 2 , Figure 4 and Figure 6As shown, among the second touch leads 4(1) to the second touch leads 4(Q), the second touch leads 4 with odd numbers are divided into a group and led out from the fourth border area K4, and in the area adjacent to the first binding area B1 close to the display area AA, along the direction from the first border area K1 to the reference center line C, the numbers of the second touch leads 4 become larger in sequence; the second touch leads 4 with even numbers are divided into a group and led out from the fourth border area K4, and in the area adjacent to the first binding area B1 close to the display area AA, along the direction from the first border area K1 to the reference center line C, the numbers of the second touch leads 4 become larger in sequence.

[0448] Exemplarily, taking the case where the number of second touch leads 4 included in the display panel 100 is 20, the 20 second touch leads 4 are divided into single array and double array according to the numbers. For example, the second touch lead 4(1), the second touch lead 4(3), ..., the second touch lead 4(9) are divided into a single array, which is led out from the fourth border area K4 and extends to the fourth pin area J4, and is correspondingly connected to the second touch pin 33(1), the second touch pin 33(3), ..., the second touch pin 33(9).

[0449] The second touch lead 4(2), the second touch lead 4(4), ..., the second touch lead 4(10) are divided into a double array, led out from the fourth border area K4, and extended to the fifth pin area J5, and are correspondingly connected to the second touch pin 33(2), the second touch pin 33(4), ..., the second touch pin 33(10).

[0450] On the side of the first binding area B1 close to the display area AA, along Figure 7 In the direction from the left side to the right side, the second touch lead 4(1), the second touch lead 4(3), ..., the second touch lead 4(9) are arranged in the order of increasing numbers.

[0451] On the side of the first binding area B1 close to the display area AA, along Figure 7 In the direction from the left side to the right side, the second touch lead 4(2), the second touch lead 4(4), ..., the second touch lead 4(10) are arranged in the order of increasing numbers.

[0452] It can be understood that when the multiple second touch leads 4 are divided into two groups and respectively led out from the fourth frame area K4, and respectively extend to the fourth pin area J4 and the fifth pin area J5, the grouped lead-out method of the multiple second touch leads 4 includes but is not limited to the above situation, and is specifically designed according to actual needs. It is only used here as an example of a possible implementation method, and is not intended to be a limitation on the specific implementation method of the present disclosure.

[0453] The following is an example in which the display panel 100 includes 20 second touch leads 4, the second touch leads 4(1) to the second touch leads 4(10) are divided into a group and are led out from the fourth frame area K4 and extend to the fourth pin area J4, and the second touch leads 4(11) to the second touch leads 4(20) are divided into a group and are led out from the fourth frame area K4 and extend to the fifth pin area J5.

[0454] In some embodiments, in the display panel 100, as Figure 4 , Figure 6 and Figure 7 As shown, the number of the second touch pins 33 is Q, which are respectively connected to the Q second touch channels 12. The Q second touch pins 33 are numbered as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (Q) in sequence. Each column of the second touch pins 33 includes N second touch pins 33 with consecutive numbers.

[0455] The second touch pins 33(1) to the second touch pins 33(Qy) are arranged in the fourth pin area J4, 1≤y<y+1≤Q, and along the direction from the first border area K1 to the reference center line C, the numbers of the second touch pins 33 in each row increase successively and are an arithmetic progression with a difference of N.

[0456] The second touch pins 33 (Q-y+1) to the second touch pins 33 (Q) are arranged in the fifth pin area J5, and along the direction from the second border area K2 to the reference center line C, the numbers of the second touch pins 33 in each row decrease successively and are an arithmetic progression with a difference of N.

[0457] The Q second touch leads 4 are divided into a plurality of subgroups Z2, each subgroup Z2 includes N second touch leads 4 located adjacently to each other. A column of second touch pins 33 includes N second touch pins 33, the N second touch leads 4 of each subgroup Z2 are respectively connected to the N second touch pins 33 of a column, and the N second touch pins 33 of each column are numbered consecutively.

[0458] It should be noted that a column of second touch pins 33 includes at least one second touch pin 33, and the consecutive numbering of the N second touch pins 33 in each column means that, when a column of second touch pins 33 includes multiple (two or more) second touch pins 33, the numbers of the multiple second touch pins 33 in the same column are consecutive, but the multiple second touch pins 33 with consecutive numbers in the same column may be arranged in sequence along the column direction in the order of the numbers, or may not be arranged in the order of the numbers.

[0459] For example, Figures 8 to 15As shown, the plurality of second touch pins 33 are arranged in three rows, the plurality of second touch pins 33 in each row are sequentially arranged along the first direction X, and each column of second touch pins 33 includes at least one second touch pin 33 .

[0460] Taking the display panel 100 including 20 second touch pins 33 as an example, according to the numbering of the second touch channels 12 corresponding to the second touch pins 33, the 20 second touch pins 33 are numbered in sequence as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (20).

[0461] The second touch pins 33(1) to 33(10) are arranged in the fourth pin area J4. The second touch pins 33 in the same row are numbered along the Figure 8 , Fig.10 , Fig.12 and Fig.14 The numbers increase from the left to the right.

[0462] The second touch pins 33 (11) to the second touch pins 33 (20) are arranged in the fifth pin area J5. The second touch pins 33 in the same row are numbered along the Fig. 9 , Fig.11 , Fig.13 and Fig.15 The numbers increase from the left to the right.

[0463] In some examples, the plurality of second touch pins 33 are arranged in three rows, such as Figure 8 , Fig.10 , Fig.12 and Fig.14 As shown, in the three rows of second touch pins 33 in the fourth pin area J4, the numbers of the second touch pins 33 in the same column are continuous, and the numbers of the second touch pins 33 in the same row increase in sequence along the first direction X and in the direction pointing to the reference center line C, and are an arithmetic progression with a difference of 3; Fig. 9 , Fig.11 , Fig.13 and Fig.15 As shown, in the three rows of second touch pins 33 in the fifth pin area J5, the second touch pins 33 in the same column are numbered continuously, and the numbers of the second touch pins 33 in the same row increase successively along the first direction X and pointing to the reference center line C, and are an arithmetic progression with a difference of 3.

The arrangement order of the second touch pin 33(1), the second touch pin 33(2) and the second touch pin 33(3) along the column direction can be increasing in sequence according to the numbering order, decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

The arrangement order of the second touch pin 33(18), the second touch pin 33(19) and the second touch pin 33(20) along the column direction can be increasing in sequence according to the numbering order, decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

[0468] The plurality of second touch pins 33 in the fourth pin area J4 and the plurality of second touch pins 33 in the fifth pin area J5 may be arranged symmetrically about the second direction Y. In this case, the second touch pin 33(1) and the second touch pin 33(20) are located in the same row, the second touch pin 33(2) and the second touch pin 33(19) are located in the same row, and the second touch pin 33(3) and the second touch pin 33(18) are located in the same row.

[0486] For example, Figures 6 to 19 As shown, among the 20 second touch leads 4 included in the display panel 100, the second touch leads 4(1) to the second touch leads 4(10) are divided into a group and are led out from the fourth frame area K4 and extend to the fourth pin area J4, and are correspondingly connected to the third touch pins 33(1) to the third touch pins 33(10); the second touch leads 4(11) to the second touch leads 4(20) are divided into a group and are led out from the fourth frame area K4 and extend to the fifth pin area J5, and are correspondingly connected to the third touch pins 33(11) to the third touch pins 33(20).

[0487] The interval between two adjacent first pins 3 (for example, the second touch pins 33) along the first direction X is 10 μm to 15 μm. Figures 8 to 19 As shown, at least a portion of the multiple second touch leads 4 pass through two adjacent second touch pins 33 to be connected to the corresponding second touch pins 33, the line width of the second touch lead 4 located between the two adjacent second touch pins 33 is, for example, 2μm to 3μm, and the line width of the second touch lead 4 located outside the fourth pin area J4 and the fifth pin area J5 is greater than or equal to 3μm.

[0488] Accordingly, in some embodiments, in the touch control and display driver integrated chip 200, for example Figure 5 , Figures 20 to 31 As shown, the number of the plurality of second touch connection blocks 73 is Q, Q ≥ 3, and they are sequentially numbered as second touch connection block 73 (1), second touch connection block 73 (2), ..., second touch connection block 73 (Q), and are configured to respectively output second touch signals to Q second touch channels 12 of the display panel 100. Each column of second touch connection blocks 73 includes N second touch connection blocks 73 with consecutive numbers.

[0489] The second touch connection blocks 73(1) to the second touch connection blocks 73(Qy) are arranged in the fourth connection area L4, 1≤y<y+1≤Q, and along the direction from the right end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the second touch connection blocks 73 in each row increase successively and are an arithmetic progression, and the difference is N.

[0490] The second touch connection blocks 73 (Q-y+1) to the second touch connection blocks 73 (Q) are arranged in the fifth connection area L5. Along the direction from the left end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the second touch connection blocks 73 in each row decrease successively and are an arithmetic progression with a difference of N.

[0491] It should be noted that a column of second touch connection blocks 73 includes at least one second touch pin 33 second touch connection block 73, and the consecutive numbering of the N second touch connection blocks 73 in each column means that, when a column of second touch connection blocks 73 includes multiple (two or more) second touch connection blocks 73, the numbers of the multiple second touch connection blocks 73 in the same column are consecutive, but the multiple second touch connection blocks 73 with consecutive numbers in the same column can be arranged in sequence along the column direction in the order of the numbers, or not in the order of the numbers.

[0492] Taking the example that the number of second touch connection blocks 73 included in the touch and display driver integrated chip 200 is 20, when the touch and display driver integrated chip 200 is connected correspondingly to the display panel 100, the multiple second touch pins 33 included in the display panel 100 are respectively connected to the multiple second touch connection blocks 73 of the touch and display driver integrated chip 200.

[0493] For example, Figures 20 to 27 As shown, the plurality of second touch connection blocks 73 are arranged in three rows, the plurality of second touch connection blocks 73 in each row are sequentially arranged along the first direction X, and each column of second touch connection blocks 73 includes at least one second touch connection block 73 .

[0494] Taking the number of the second touch connection blocks 73 included in the touch and display driver integrated chip 200 as 20 as an example, when the touch and display driver integrated chip 200 is connected to the display panel 100, the plurality of second touch pins 33 included in the display panel 100 are respectively connected to the plurality of second touch connection blocks 73 of the touch and display driver integrated chip 200. According to the numbering of the second touch pins 33 connected to the second touch connection blocks 73, the 20 second touch connection blocks 73 are numbered in sequence as second touch connection block 73 (1), second touch connection block 73 (2), ..., second touch connection block 73 (20).

[0495] The second touch connection blocks 73(1) to the second touch connection blocks 73(10) are arranged in the fourth connection area L4. The second touch connection blocks 73 in the same row are numbered along the Fig. 20 , Fig. 22 , Fig.24 and Fig.26 The numbers in the figure decrease from left to right.

[0496] The second touch connection blocks 73 (11) to the second touch connection blocks 73 (20) are arranged in the fifth connection area L5. The second touch connection blocks 73 in the same row are numbered along the Fig.21 , Fig.23 , Fig.25 and Fig. 27 The numbers in the figure increase as they point from the right side to the left side.

[0497] In some examples, the plurality of second touch connection blocks 73 are arranged in three rows, such as Fig. 20 , Fig. 22 , Fig.24 and Fig.26 As shown, in the three rows of second touch connection blocks 73 in the fourth connection area L4, the numbers of the second touch connection blocks 73 in the same column are continuous, and the numbers of the second touch connection blocks 73 in the same row decrease in sequence from the left end to the right end of the touch and display driver integrated chip 200, and are an arithmetic progression with a difference of 3; Fig.21 , Fig.23 , Fig.25 and Fig. 27 As shown, in the three rows of second touch connection blocks 73 in the fifth connection area L5, the numbers of the second touch connection blocks 73 in the same column are continuous, and the numbers of the second touch connection blocks 73 in the same row decrease successively from the left end to the right end of the touch and display driver integrated chip 200, and are an arithmetic progression with a difference of 3.

The arrangement order of the second touch connection block 73(8), the second touch connection block 73(9) and the second touch connection block 73(10) along the column direction can be increasing in sequence according to the numbering order, or decreasing in sequence according to the numbering order, or not arranged in sequence according to the numbering order.

[0510] Fig.28 and Fig.29 In the embodiment, the specific arrangement of the second touch connection blocks 73 arranged in four rows is only used as an exemplary description and is not intended to limit the specific implementation of the present disclosure.

The symmetrical arrangement mentioned here means that the arrangement path of the plurality of second touch connection blocks 73 in the fourth connection area L4 from small to large in number and the arrangement path of the plurality of second touch connection blocks 73 in the fifth connection area L5 from large to small in number are symmetrical with respect to the second direction Y.

[0517] Fig.30 and Fig.31 In the embodiment, the specific arrangement of the second touch connection blocks 73 arranged in five rows is only used as an exemplary description and is not intended to limit the specific implementation of the present disclosure.

[0518] It should be noted that, in the touch and display driver integrated chip 200, the multiple second touch connection blocks 73 can also be arranged in 2 rows, 6 rows, 7 rows or more rows. The specific number and arrangement of the second touch connection blocks 73 are designed accordingly according to actual needs. It can be understood that the arrangement of the multiple second touch connection blocks 73 includes but is not limited to the above examples, which are only used as illustrative illustrations and not as a limitation on the specific embodiments of the present disclosure.

[0519] In some embodiments, in the display panel 100, as Fig.32 and Fig.33 As shown, the number of the plurality of second touch pins 33 is N×Q, Q≥3, and they are arranged in N rows and Q columns. The Q second touch pins 33 in each row are numbered as second touch pin 33(1), second touch pin 33(2), ..., second touch pin 33(Q) in sequence; the N second touch pins 33 in each column are numbered the same, and the second touch pins 33 in the Q columns are connected to Q second touch leads 4 respectively.

[0520] The second touch pins 33 (1) to 33 (Qy) are arranged in the fourth connection area L4, 1≤y<y+1≤Q, and along the direction from the first border area K1 to the reference center line C, the numbers of the second touch pins 33 increase successively and are continuous.

[0521] The second touch pins 33 (Q-y+1) to the second touch pins 33 (Q) are arranged in the fifth connection area L5, and along the direction from the second frame area K2 to the reference center line C, the numbers of the second touch pins 33 decrease successively and are continuous.

[0522] For example, Fig.32 and Fig.33 As shown, among the N rows of second touch pins 33 arranged in the first binding area B1 of the display panel 100, when the multiple second touch pins 33 in the same column have the same number, each second touch lead 4 overlaps with a corresponding column of second touch pins 33, and the line width of the portion of the second touch lead 4 located in the first binding area B1 is equal to the line width of the portion located outside the first binding area B1.

[0523] For example, Fig.32 and Fig.33 As shown, the line width of the second touch-control leads 4 is greater than or equal to 10 μm, and the interval between two adjacent second touch-control leads 4 is greater than or equal to 10 μm.

[0524] With such a design, when each touch lead CK (for example, the second touch lead 4) is connected to its corresponding first touch pin 31, the second touch lead 4 does not need to pass through the gap area between adjacent second touch pins 33. Therefore, the line width of the portion where the second touch lead 4 is connected to the corresponding second touch pin 33 can be larger. Accordingly, the line resistance of the second touch lead 4 is smaller, which is beneficial to reducing the power consumption of the display panel 100. At the same time, the increase in the line width of the second touch lead 4 also increases the reliability of the second touch lead 4, avoiding the problem of the second touch lead 4 being easily broken due to the second touch lead 4 having a too small line width.

[0525] It should be noted that, when the numbers of the second touch pins 33 in the same column are the same, Fig.32 and Fig.33As shown, the same column may include a plurality of second touch pins 33 with the same individual number, such as Fig.34 and Fig.35 As shown, the same column may also include a second touch pin 33 extending along the column direction.

[0526] For example, Fig.32 and Fig.33 As shown, the display panel 100 includes 20 second touch leads 4 and 60 second touch pins 33. The 60 second touch pins 33 are arranged in 3 rows and 20 columns. Each column of second touch pins 33 includes at least one second touch pin 33 with the same number. In the 3 rows of second touch pins 33 in the fourth pin area J4, the numbers of the plurality of second touch pins 33 in each row are arranged in the order of Fig.32 In the direction from the left to the right in the fifth pin area J5, the numbers of the plurality of second touch pins 33 in each row are arranged in the order of Fig.33 The directions from the right side to the left side become larger.

[0527] In this case, in the three rows of second touch pins 33 in the fourth pin area J4, the second touch pins 33 in the same row are numbered continuously; in the three rows of second touch pins 33 in the fifth pin area J5, the second touch pins 33 in the same row are numbered continuously.

[0528] It should be noted that, when the multiple second touch leads 4 are divided into single-array and double-array and are respectively led out to the fourth connection area L4 and the fifth connection area L5, in the three rows of second touch leads 4 in the fourth connection area L4, the second touch leads 4 in each row are numbered as an arithmetic progression with a difference of 2; in the three rows of second touch leads 4 in the fifth connection area L5, the second touch leads 4 in each row are numbered as an arithmetic progression with a difference of 2.

[0529] Accordingly, in some embodiments, in the touch and display driver integrated chip 200, the number of the plurality of second touch connection blocks 73 is N×Q, Q≥3, and they are arranged in N rows and Q columns; the Q second touch connection blocks 73 in each row are numbered as second touch connection block 73(1), second touch connection block 73(2), ..., second touch connection block 73(Q) in sequence. The N second touch connection blocks 73 in each column are numbered the same, and the Q second touch connection blocks 73 in the columns are configured to output second touch signals to the Q second touch channels 12, respectively.

[0530] The second touch connection blocks 73(1) to the second touch connection blocks 73(Qy) are arranged in the fourth connection area L4, 1≤y<y+1≤Q, and along the direction from the right end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the second touch connection blocks 73 become larger in sequence and the numbers are continuous.

[0531] The second touch connection block 73 (Q-y+1) to the second touch connection block 73 (Q) are arranged in the fifth connection area L5, and along the direction from the left end of the touch and display driver integrated chip 200 to the center of the touch and display driver integrated chip 200, the numbers of the second touch connection blocks 73 become smaller and the numbers are continuous.

[0532] Exemplarily, the touch and display driver integrated chip 200 includes 120 second touch connection blocks 73, and the 120 second touch connection blocks 73 are arranged in 3 rows and 40 columns, and each column of second touch connection blocks 73 includes 3 second touch connection blocks 73 with the same number. In the 3 rows of second touch connection blocks 73 in the fourth connection area L4, the numbers of the multiple second touch connection blocks 73 in the same row increase in sequence along the first direction X and along the direction from the first frame area K1 to the reference center line C; in the 3 rows of second touch connection blocks 73 in the fifth connection area L5, the numbers of the multiple second touch connection blocks 73 in the same row increase in sequence along the direction from the left end to the right end of the touch and display driver integrated chip 200.

[0533] In this case, in the three rows of second touch connection blocks 73 in the fourth connection area L4, the second touch connection blocks 73 in the same row are numbered continuously; in the three rows of second touch connection blocks 73 in the fifth connection area L5, the second touch connection blocks 73 in the same row are numbered continuously.

[0534] It can be understood that, when the display panel 100 connected to the touch and display driver integrated chip 200 includes multiple second touch leads 4 divided into single array and double array and respectively led out to the fourth pin area J4 and the fifth pin area J5, among the three rows of multiple second touch connection blocks 73 in the fourth connection area L4, the multiple second touch connection blocks 73 in the same row are numbered as an arithmetic progression with a difference of 2; among the three rows of multiple second touch connection blocks 73 in the fifth connection area L5, the multiple second touch connection blocks 73 in the same row are numbered as an arithmetic progression with a difference of 2.

[0535] In some embodiments, Figure 4 , Figure 36 to Figure 39 As shown, in each second binding area B2 of the display panel 100, a plurality of second pins 6 are arranged in at least one column along the second direction Y. When the plurality of second pins 6 are arranged in a plurality of columns along the second direction Y, the plurality of columns of second pins 6 are arranged in parallel and at intervals along the first direction X.

[0536] Exemplarily, there is a gap between two adjacent second pins 6 in the same column, and the second pins 6 in two adjacent columns are staggered in the first direction X.

[0537] like Figure 4As shown, when the plurality of second pins 6 in each second binding area B2 are arranged in multiple columns and multiple rows, any two adjacent columns of second pins 6 are staggered in the row direction. On the one hand, when the touch lead CK (for example, the third touch lead 5) needs to pass through the interval area between two adjacent second pins 6 to be connected to the corresponding second pin 6, the wiring path of the third touch lead 5 is simpler, and the number of corners of the third touch lead 5 is reduced. It can be understood that the third touch lead 5 is prone to breakage at the corner position. By reducing the number of corners of the third touch lead 5, the reliability of the third touch lead 5 can be increased and the risk of breakage of the third touch lead 5 can be reduced. On the other hand, when the display panel 100 and the touch and display driver integrated chip 200 are bound by ACF, the staggered arrangement of the second pins 6 can make the ACF better in the connection tightness between the display panel 100 and the touch and display driver integrated chip 200, ensure the binding reliability between the display panel 100 and the touch and display driver integrated chip 200, and then ensure the stability and reliability of signal transmission.

[0538] In some embodiments, Figure 4 , Figure 36 to Figure 39 As shown, the display panel 100 includes Q second pins 6, which are respectively connected to Q second touch channels 12. According to the number of the second touch channels 12 corresponding to the second pins 6, the Q second pins 6 are numbered as second pin 6 (1), second pin 6 (2), ..., second pin 6 (Q). The two second binding areas B2 are the second binding area B2 (A) and the second binding area B2 (B). The second binding area B2 (A) is located on the side of the reference center line C close to the first frame area K1, and the second binding area B2 (B) is located on the side of the reference center line C close to the second frame area K2.

[0539] The second pins 6(1) to the second pins 6(Qy) are arranged in the second binding area B2(A), 1≤y<y+1≤Q, along the second direction Y and from the third frame area K3 to the fourth frame area K4, the number of the second pins 6 in each column increases successively and is an arithmetic progression. The second pins 6(Q-y+1) to the second pins 6(Q) are arranged in the second binding area B2(B), along the second direction Y and from the third frame area K3 to the fourth frame area K4, the number of the second pins 6 in each column decreases successively and is an arithmetic progression.

[0540] In some embodiments, Figure 4 , Figure 6 and Figure 7As shown, the display panel 100 further includes a plurality of third touch leads 5, the number of which is Q, and they are respectively connected to the Q second touch channels 12. According to the numbering of the second touch channels 12 correspondingly connected to the third touch leads 5, the Q third touch leads 5 are sequentially numbered as the third touch lead 5 (1), the third touch lead 5 (2), ..., the third touch lead 5 (Q).

[0541] The third touch leads 5(1) to the third touch leads 5(Qy) are led out from the third border area K3 and extend toward the first border area K1; and in an area adjacent to the second binding area B2(A) and away from the first binding area B1, along the first direction X and from the first border area K1 to the second border area K2, the numbers of the third touch leads 5 become smaller successively.

[0542] The third touch lead 5 (Q-y+1) to the third touch lead 5 (Q) is led out from the third border area K3 and extends to the second border area K2; and in the area adjacent to the second binding area B2 (B) and away from the first binding area B1, along the first direction X and from the second border area K2 to the first border area K1, the numbers of the third touch leads 5 become larger successively.

[0543] For example, Figure 7 , Fig.36 and Fig.37 As shown, one end of each third touch lead 5 is connected to a second touch channel 12, and the other end is connected to a second pin 6. Each second pin 6 is connected to a second touch channel 12 via a third touch lead 5.

[0544] The second touch channel 12, the third touch lead 5 and the second pin 6 are connected according to the corresponding numbers. For example, the second touch channel 12 (R), the third touch lead 5 (R) and the second pin 6 (R) are connected in sequence, 1≤R≤Q.

[0545] For example, Figure 7 , Fig.36 and Fig.37 As shown, the display panel 100 includes 20 third touch leads 5 as an example. Among the 20 third touch leads 5, the third touch leads 5 (1) to the third touch leads 5 (10) are divided into a group and are led out from the third frame area K3, extend through the first frame area K1 to the second binding area B2 (A), and are connected to the second pins 6 (1) to the second pins 6 (10) correspondingly; along Figure 7 and Fig.36 In the direction where the left side points to the right side, the third touch leads 5 ( 1 ) to the third touch leads 5 ( 10 ) are arranged in sequence, for example, in the order of numbers.

[0546] The third touch leads 5 (11) to the third touch leads 5 (20) are divided into a group and led out from the third frame area K3, extending through the second frame area K2 to the second binding area B2 (B), and correspondingly connected to the second pins 6 (11) to the second pins 6 (20); along Figure 7 and Fig.37 In the direction where the left side points to the right side, the third touch leads 5 (11) to the third touch leads 5 (20) are arranged in sequence, for example, in the order of numbers.

[0547] On the side of the first binding area B1 close to the display area AA, along Figure 7 and Fig.36 In the direction from the right side to the left side, the third touch lead 5(1), the third touch lead 5(2), ..., the third touch lead 5(10) are arranged in the order of increasing numbers, along Figure 7 and Fig.37 In the direction from the right side to the left side, the third touch lead 5 (11), the third touch lead 5 (12), ..., the third touch lead 5 (20) are arranged in the order of increasing numbers.

[0548] In some other embodiments, in the display panel 100, as shown in FIG. Figure 4 , Figure 6 and Figure 7 As shown, among the third touch leads 5(1) to the third touch leads 5(Q), the third touch leads 5 with odd numbers are divided into a group and led out from the third frame area K3, extending through the first frame area K1 to the second binding area B2(A), and correspondingly connected to the second pins 6(1) to the second pins 6(10); in the area adjacent to the second binding area B2(A) close to the display area AA, along the direction from the first frame area K1 to the reference center line C, the numbers of the third touch leads 5 decrease successively; the third touch leads 5 with even numbers are divided into a group and led out from the third frame area K3, extending through the second frame area K2 to the second binding area B2(B), and correspondingly connected to the second pins 6(11) to the second pins 6(20); in the area adjacent to the first binding area B1 close to the display area AA, along the direction from the second frame area K2 to the reference center line C, the numbers of the third touch leads 5 increase successively.

[0549] Exemplarily, taking the display panel 100 including 20 third touch leads 5 as an example, the 20 third touch leads 5 are divided into single array and double array according to the numbers. For example, the third touch lead 5(1), the third touch lead 5(3), ..., the third touch lead 5(9) are divided into a single array, which is led out from the third border area K2 and extends to the second binding area B2(A), and is correspondingly connected to the second pin 6(1), the second pin 6(3), ..., the second pin 6(9).

[0550] The third touch lead 5(2), the third touch lead 5(4), ..., the third touch lead 5(10) are divided into a double array, led out from the third border area K3, and extended to the second binding area B2(B), and correspondingly connected to the second pin 6(2), the second pin 6(4), ..., the second pin 6(10).

[0551] On the side of the second binding area B2(A) close to the first border area K1, along Fig.36 In the direction from the left side to the right side, the third touch lead 5(1), the third touch lead 5(3), ..., the third touch lead 5(9) are arranged in descending order of number.

[0552] On the side of the second binding area B2 (B) close to the second border area K2, along Fig.37 In the direction from the right side of the diagram to the left side, the third touch lead 5(2), the third touch lead 5(4), ..., the third touch lead 5(10) are arranged in the order of increasing numbers.

[0553] It can be understood that when the multiple third touch leads 5 are divided into two groups and respectively led out from the third border area K3, and respectively extend to the second binding area B2 (A) and the second binding area B2 (B), the grouping and leading-out method of the multiple third touch leads 5 includes but is not limited to the above situation, and is specifically designed according to actual needs. It is only used here as an example of a possible implementation method, and not as a limitation on the specific implementation method of the present disclosure.

[0554] The following is an example in which the display panel 100 includes 20 third touch leads 5, the third touch leads 5 (1) to the first touch leads 2 (10) are divided into a group, led out from the third frame area K3, and extended to the second binding area B2 (A), and the third touch leads 5 (11) to the third touch leads 5 (20) are divided into a group, led out from the third frame area K3, and extended to the second binding area B2 (B).

[0555] In some embodiments, in the display panel 100, as Figure 4 , Fig.36 and Fig.37 As shown, the number of second pins 6 is Q, which are respectively connected to Q second touch channels 12, and the Q second pins 6 are numbered as second pin 6 (1), second pin 6 (2), ..., second pin 6 (Q) in sequence. The Q second pins 6 are arranged in K columns, K ≥ 1, and the numbers of the second pins 6 in the same column increase in sequence and are an arithmetic progression, with a difference of K.

[0556] The second pin 6 (1) to the second pin 6 (Qy) are arranged in the second binding area B2 (A), and the second pin 6 (Q-y+1) to the second pin 6 (Q) are arranged in the second binding area B2 (B), 1≤y<y+1≤Q.

[0557] The Q third touch leads 5 are divided into a plurality of subgroups Z3, each of which includes K adjacent third touch leads 5. A row of second pins 6 includes K second pins 6, and the K third touch leads 5 of each subgroup Z3 are respectively connected to the K second pins 6 in the same row.

[0558] Exemplarily, K≥2. Among the plurality of second pins 6 in the second binding area B2(A), the second pins 6 in the same row are numbered continuously; among the plurality of second pins 6 in the second binding area B2(B), the second pins 6 in the same row are numbered continuously.

[0559] It should be noted that a row of second pins 6 includes at least one second pin 6, and continuous numbering of the second pins 6 in the same row means that, when a row of second pins 6 includes multiple (two or more) second pins 6, the numbers of the multiple second pins 6 in the same row are continuous, but the multiple second pins 6 with consecutive numbers in the same row may be arranged in sequence along the row direction in the order of the numbers, or not in the order of the numbers.

[0560] Taking the display panel 100 including 20 second pins 6 as an example, according to the numbering of the second touch channels 12 connected to the second pins 6, the 20 second pins 6 are numbered as second pin 6 (1), second pin 6 (2), ..., second pin 6 (20) in sequence.

[0561] The second pins 6 (1) to the second pins 6 (10) are arranged in the second binding area B2 (A), and the second pins 6 in the same row are numbered along Fig.36 The numbers in the figure decrease from left to right.

[0562] The second pins 6 (11) to the second pins 6 (20) are arranged in the second binding area B2 (B), and the second pins 6 in the same row are numbered along Fig.37 The numbers in the figure decrease from left to right.

[0563] In some examples, such as Fig.36 and Fig.37 As shown, the 10 second pins 6 in the second binding area B2 (A) are arranged in 2 columns and 5 rows, and the 10 second pins 6 in the second binding area B2 (B) are arranged in 2 columns and 5 rows. The plurality of second touch pins 33 in each column are arranged in sequence along the second direction Y, for example, and each column of second pins 6 includes five second pins 6.

[0564] along Fig.36The five second pins 6 in the first column of the second pins 6 in the direction from the right side to the left side are respectively the second pin 6(1), the second pin 6(3), the second pin 6(5), the second pin 6(7) and the second pin 6(9). The arrangement order of the second pin 6(1), the second pin 6(3), the second pin 6(5), the second pin 6(7) and the second pin 6(9) in the column direction and in the direction from the third border area K3 to the fourth border area K4 can be increased in the order of numbering, and is an arithmetic progression with a difference of 2.

[0565] along Fig.37 The five second pins 6 in the first column of the second pins 6 in the direction from the left side to the right side are respectively the second pin 6 (16), the second pin 6 (17), the second pin 6 (18), the second pin 6 (19) and the second pin 6 (20). The arrangement order of the second pin 6 (16), the second pin 6 (17), the second pin 6 (18), the second pin 6 (19) and the second pin 6 (20) in the column direction and in the direction from the third border area K3 to the fourth border area K4 can be reduced in the order of numbers and be an arithmetic progression with a difference of 2.

[0566] The multiple second pins 6 in the second binding area B2(A) and the multiple second pins 6 in the second binding area B2(B) can be arranged symmetrically about the second direction Y. In this case, the second pin 6(1) and the second pin 6(20) are in the same row, the second pin 6(2) and the second pin 6(19) are in the same row, the second pin 6(3) and the second pin 6(18) are in the same row, the second pin 6(4) and the second pin 6(17) are in the same row, and the second pin 6(5) and the second pin 6(16) are in the same row. The symmetrical arrangement described here means that the arrangement path of the multiple second pins 6 in the second binding area B2(A) from small to large according to the numbering, and the arrangement path of the multiple second pins 6 in the second binding area B2(B) from large to small according to the numbering are symmetrical about the second direction Y.

[0567] Fig.36 and Fig.37 In the present invention, the specific arrangement of the second touch pins 33 arranged in two rows is only used as an exemplary description and is not intended to limit the specific implementation of the present disclosure.

[0568] In other examples, such as Fig.38 and Fig.39 As shown, the 10 second pins 6 in the second binding area B2 (A) are arranged in 3 columns and 4 rows, and the 10 second pins 6 in the second binding area B2 (B) are arranged in 3 columns and 4 rows. The plurality of second pins 6 in each column are arranged in sequence along the second direction Y, for example, and each column of second pins 6 includes five second pins 6.

[0569] It should be noted that the arrangement direction (column direction) of the multiple second pins 6 in each column may also form an acute angle with the second direction Y, and the multiple second pins 6 in the second binding area B2 (A) and / or the second binding area B2 (B) may also be arranged in 1 column, 4 columns or more columns, and the number of second pins 6 in the second binding area B2 (A) and the second binding area B2 (B) may be the same or different, and the specific design shall be made according to actual needs. The above is only an exemplary description of possible implementation methods and does not serve as a limitation on the specific implementation methods of the present disclosure.

[0570] like Fig.38 and Fig.39 As shown, the plurality of second pins 6 in the second binding area B2 (A) and the second binding area B2 (B) are arranged in 3 columns and 4 rows, for example. It can be understood that when the second pins 6 are arranged at each position in the 3 columns and 4 rows, a total of 24 second pins 6 are arranged in the display panel 100. The display panel 100 includes, for example, 20 second touch channels 12, and the 20 second pins 6 can transmit signals to the 20 second touch channels 12 respectively. In this case, during the preparation of the display panel 100, when the second touch channels 12 are connected to the second pins 6 correspondingly, the extra 4 second pins 6 may not be connected to the touch signal line (for example, the third touch lead 5, etc.), do not transmit the touch signal, and serve as virtual pins 37. At least a portion of the second pins 6 serving as virtual pins 37 (not connected to the touch signal line, and do not transmit the touch signal) may also be connected to other signals as needed in the subsequent preparation process. The specific access signal is designed accordingly according to actual needs, which is only used as an exemplary description of possible implementation methods and not as a limitation on the specific implementation methods of the present disclosure.

[0571] In some embodiments, Figure 36 to Figure 39 As shown, a portion of the multiple third touch leads 5 included in the display panel 100 passes through the gaps between the second pins 6 arranged adjacently along the first direction X and is connected to the corresponding second pins 6, and the line width of the portion of the third touch leads 5 located in the gaps is smaller than the line width of the portion located outside the second binding area B2.

[0572] Exemplarily, the line width of the third touch lead 5 located between two adjacent second pins 6 is, for example, 2μm to 3μm, and the line width of the third touch lead 5 located outside the second binding area B2(A) and / or the second binding area B2(B) is greater than or equal to 3μm.

[0573] Exemplarily, the interval between adjacent third touch-control leads 5 is 13 μm.

[0574] In some embodiments, Figure 4 , Fig.40 , Fig.41and Fig.42 As shown, in the case where the multiple second touch pins 33 in the first binding area B1 of the display panel 100 are arranged in N rows and Q columns, the multiple second touch pins 33 in the same column have the same number, and the second touch pins 33 are configured to receive the second touch signal and transmit the second touch signal to the touch structure 1, the display panel 100 also includes: a plurality of fourth touch leads 8, connected to the touch structure 1.

[0575] A plurality of fourth touch leads 8 are led out from the third frame area K3, divided into two groups, respectively passing through the first frame area K1 and the second frame area K2, and extending to the fourth pin area J4 and the fifth pin area J5. The two groups of fourth touch leads 8 are respectively connected to the two groups of second touch pins 33.

[0576] Exemplarily, one end of each fourth touch lead 8 is connected to a second touch channel 12 , and the other end is connected to a column of second touch pins 33 .

[0577] In some embodiments, Fig.40 As shown, the display panel 100 includes Q fourth touch leads 8 , which are respectively connected to Q second touch channels 12 .

[0578] Exemplarily, the line width of the fourth touch-control leads 8 is greater than or equal to 10 μm, and the interval between two adjacent fourth touch-control leads 8 is greater than or equal to 10 μm.

[0579] Exemplarily, one end of each fourth touch lead 8 is connected to a second touch channel 12, and the other end is connected to a column of second touch pins 33. The second touch pins 33 are configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 through the fourth touch lead 8.

[0580] For example, the second touch pin 33 is configured to receive a second touch signal and transmit the second touch signal to the second touch channel 12 through the fourth touch lead 8 .

[0581] According to the numbering of the second touch channels 12 corresponding to the fourth touch leads 8, the Q fourth touch leads 8 are numbered as the fourth touch lead 8(1), the fourth touch lead 8(2), ..., the fourth touch lead 8(Q). According to the numbering of the second touch channels 12 corresponding to the second touch pins 33, the Q second touch pins 33 are numbered as the second touch pin 33(1), the second touch pin 33(2), ..., the second touch pin 33(Q).

[0582] It should be noted that, when the second touch pins 33 in the Q column are numbered sequentially as the second touch pin 33 (1), the second touch pin 33 (2), ..., the second touch pin 33 (Q), the numbers of the second touch pins 33 in the same column are the same, and the numbers of the second touch pins 33 in different columns are different.

[0583] The second touch channel 12, the fourth touch lead 8 and the second touch pin 33 are connected according to the corresponding numbers. For example, the second touch channel 12 (R), the fourth touch lead 8 (R) and the second touch pin 33 (R) are connected in sequence, 1≤R≤Q. The second touch pin 33 (R) is a row of second touch pins 33 (R) with the same number.

[0584] Exemplarily, when multiple second touch pins 33(R) in the same column have the same number, the multiple second touch pins 33(R) in the same column are electrically connected, and when connected to any one of the second touch pins 33(R), all the second touch pins 33(R) with the same number in this column can be electrically connected.

[0585] The touch structure 1 includes 20 second touch channels 12 as an example for description. Along the direction from the first frame area K1 to the second frame area K2, the 20 second touch channels 12 are numbered as second touch channel 12 (1), second touch channel 12 (2), ..., second touch channel 12 (20) in sequence. According to the numbering of the second touch channels 12 corresponding to the fourth touch leads 8, the 20 fourth touch leads 8 are numbered as fourth touch leads 8 (1), fourth touch leads 8 (2), ..., fourth touch leads 8 (40) in sequence.

[0586] The display panel 100 includes 20 fourth touch leads 8 and 60 second touch pins 33. According to the numbering of the second touch channels 12 corresponding to the second touch pins 33, the 20 columns of second touch pins 33 are numbered as second touch pin 33 (1), second touch pin 33 (2), ..., second touch pin 33 (20) in sequence, wherein the second touch pins 33 in each column have the same numbering, and the fourth touch leads 8 corresponding to a column of second touch pins 33 with the same numbering are all connected to the second touch pins 33 in this column.

[0587] It should be noted that the fourth touch lead 8 corresponding to a column of second touch pins 33 with the same number is connected to all the second touch pins 33 in this column. It can be that multiple second touch pins 33 with the same number in the same column are electrically connected. When the fourth touch lead 8 is connected to any one of the second touch pins 33, it can be electrically connected to all the second touch pins 33 with the same number in this column; it can also be that the fourth touch lead 8 is electrically connected to multiple second touch pins 33 with the same number in this column. It can be understood that in order to ensure the normal transmission of the touch signal, the corresponding touch pin (such as the second touch pin 33) and the touch lead CK (such as the fourth touch lead 8) can be connected to achieve signal transmission. This is only an exemplary description and not a limitation of the present disclosure.

[0588] When the display panel 100 includes multiple second touch leads 2 and multiple fourth touch leads 8, the two ends of each second touch channel 12 are connected to the corresponding second touch pin 33 through a second touch lead 2 and a fourth touch lead 8, respectively. In this way, the second touch signal is transmitted from the second touch pin 33 to the two ends of the second touch channel 12, respectively, which can reduce the signal path loss of the second touch signal on the transmission path (for example, the second touch signal generates signal distortion during the transmission process due to the long transmission path, etc.), thereby ensuring the transmission reliability of the second touch signal.

[0589] Accordingly, in some embodiments, Figure 5 As shown, in each second output area S2 of the touch and display driver integrated chip 200, a plurality of second connection blocks 8 are arranged in at least one column along the second direction Y. The second direction Y is perpendicular to the first direction X, or the angle between the second direction Y and the first direction X is an acute angle. When the plurality of second connection blocks 8 are arranged in a plurality of columns along the second direction Y, the plurality of columns of second connection blocks 8 are arranged in parallel and at intervals along the first direction X.

[0590] Exemplarily, when the included angle between the second direction Y and the first direction X is an acute angle, the included angle formed by the second direction Y and the first direction X is greater than or equal to 60° and less than 90°.

[0591] In some examples, the angle formed by the second direction Y and the first direction X is greater than or equal to 75° and less than 90°.

[0592] The following description will be made by taking as an example a case where a plurality of second connection blocks 8 are arranged in at least one row and the arrangement direction of the second connection blocks 8 in each row is perpendicular to the first direction X.

[0593] Exemplarily, in the touch control and display driver integrated chip 200 , there is a gap between two adjacent second connection blocks 8 in the same column, and the second connection blocks 8 in two adjacent columns are staggered in the first direction X.

[0594] Accordingly, in some embodiments, Figure 5 As shown, the number of second connection blocks 8 included in the touch and display driver integrated chip 200 is Q, Q ≥ 3, which are numbered as second connection block 8 (1), second connection block 8 (2), ..., second connection block 8 (Q) in sequence, and are configured to output second touch signals to Q second touch channels 12 of the display panel 100 respectively.

[0595] The second connection blocks 8 (1) to the second connection blocks 8 (Qy) are arranged in the second output area S2 at the right end of the touch and display driver integrated chip 200, 1≤y<y+1≤Q, along the second direction Y and from the first output area S1 to the input area R1, and the numbers of the second connection blocks 8 in each column increase successively and are an arithmetic progression.

[0596] The second connecting blocks 8 (Q-y+1) to the second connecting blocks 8 (Q) are arranged in the second output area S2 at the left end of the touch and display driver integrated chip 200, along the second direction Y and from the first output area S1 to the input area R1, and the numbers of the second connecting blocks 8 in each column decrease successively and are an arithmetic progression.

[0597] Exemplarily, the touch and display driver integrated chip 200 is connected to the display panel 100 correspondingly, and the display panel 100 has a display area AA, a first binding area B1 located on one side of the display area AA for binding the touch and display driver integrated chip 200, and a second binding area 2(A) and a second binding area 2(B) located on a side of the first binding area B1 away from the display area AA, and the second binding area 2(A) and the second binding area 2(B) are respectively arranged at two ends of the first binding area B1. The display panel 100 has a touch structure 1, and a plurality of second pins 6 are arranged in the second binding area 2(A) and the second binding area 2(B) of the touch and display driver integrated chip 200, and the second pins 6 are configured to receive a second touch signal and transmit the second touch signal to the touch structure 1 of the display panel 100, or are configured not to be connected to the touch signal line (not to transmit the second touch signal to the touch structure 1).

[0601] In other examples, the arrangement of the plurality of second pins 6 in the second binding area B2 (A) of the display panel 100 is as follows: Fig.38 As shown, the arrangement of the plurality of second pins 6 in the second binding area B2 (B) is as follows Fig.39 In this case, Figure 5 As shown, for example, 12 second connection blocks 8 are provided in the two second output areas S2 of the touch and display driver integrated chip 200. The touch and display driver integrated chip 200 includes 24 second connection blocks 8, of which 20 second connection blocks 8 are configured to output touch signals, and 4 second connection blocks 8 are configured not to output touch signals.

[0602] The second connection blocks 8(1) to 8(10) are arranged in the second output area S2 at the right end of the touch and display driver integrated chip 200. The second connection blocks 8(1) to 8(10) are arranged in three columns and four rows, pointing from the right end to the left end of the touch and display driver integrated chip 200. The second connection blocks 8 in the first column are the second connection block 8(1), the second connection block 8(7), the second connection block 8(7) and the second connection block 8(10) in sequence.

[0603] The second connection blocks 8 (11) to the second connection blocks 8 (20) are arranged in the second output area S2 at the left end of the touch control and display driver integrated chip 200. The second connection blocks 8 (11) to the second connection blocks 8 (20) are arranged in three columns and four rows, pointing from the right end of the touch control and display driver integrated chip 200 to the left end.

[0604] It should be noted that the second connection blocks 8 configured not to output touch signals among the plurality of second connection blocks 8 serve as virtual connection blocks 77. At least a portion of the second connection blocks 8 serving as virtual connection blocks 77 (not outputting touch signals) may also be configured to output other signals as required, and the corresponding design is specifically performed according to actual needs, which is only used as an exemplary description here and is not intended to limit the specific implementation of the present disclosure.

[0605] The specific arrangement of the multiple second connection blocks 8 included in the touch and display driver integrated chip 200 includes but is not limited to the above examples, and the number of second connection blocks 8 set in the two second output areas S2 of the touch and display driver integrated chip 200 may also be different, for example, a second connection block 8 is set in the second output area S2 at the left end, and no second connection block 8 is set in the second output area S2 at the right end, and a is not 0; or, a second connection block 8 is set in the second output area S2 at the left end, and b second connection blocks 8 are set in the second output area S2 at the right end, and a≠b. The corresponding design is made according to actual needs, which is only used as an exemplary description here, and is not used as a limitation on the specific implementation of the present disclosure.

[0606] In some embodiments, Figures 9 to 19 , Fig.32 and Fig.33 ,and Fig.41 and Fig.42 As shown, the display panel 100 further includes a shielding line 9 located between adjacent first touch leads 2 and second touch leads 4. The plurality of first pins 3 further include a plurality of shielding pins 34 located between adjacent first touch pins 31 and second touch pins 33; the shielding pins 34 are connected to the shielding line 9.

[0607] Exemplarily, the shielding pin 34 is configured to receive a shielding signal. The shielding signal is, for example, a constant voltage signal, such as a ground signal GND or a voltage signal VDD.

[0608] When the first touch pin 31 is configured to receive a first touch signal and transmit the first touch signal to the touch structure 1, and the second touch pin 33 is configured to receive a second touch signal and transmit the second touch signal to the touch structure 1, a shielding pin 34 is set between adjacent first touch pins 31 and second touch pins 33, and the adjacent first touch leads 2 and second touch leads 4 are separated, and the adjacent first touch pins 31 and second touch pins 33 are separated by the shielding signal transmitted by the shielding pin 34 and the shielding line 9, thereby preventing crosstalk between the first touch signal and the second touch signal, thereby ensuring the transmission stability and reliability of touch signals (for example, the first touch signal and / or the second touch signal).

[0609] It is understandable that, when the second touch pin 33 is configured not to transmit a touch signal, the display panel 100 does not include the second touch lead 4, and a shielding pin 34 may or may not be provided between the adjacent first touch pin 31 and the second touch pin 33. In this case, the multiple shielding pins 34 provided may be connected to a shielding signal, or may not be connected to a signal, as virtual pins 37. At least a portion of the shielding pins 34 that are virtual pins 37 (not connected to a shielding signal) may also be connected to other signals as needed. The specific connected signal is designed accordingly according to actual needs, and is only used as an exemplary description of a possible implementation method, and is not intended to be a limitation on the specific implementation methods of the present disclosure.

[0610] Accordingly, in some embodiments, in the touch control and display driver integrated chip 200, for example Figures 20 to 31 As shown, the plurality of first connection blocks 7 further include: a plurality of shielding connection blocks 74 . ...
