EMBODIMENTS OF THE INVENTION

[0041] Now, exemplary embodiments will be described in detail with reference to the drawings. However, the embodiments may be implemented in various forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to fully disclose the present disclosure and to fully convey the concepts of the exemplary embodiments to those skilled in the relevant technical field. Like reference numerals in the drawings denote like or similar structures, and a detailed description is omitted. Furthermore, the drawings are merely schematic representations of the present disclosure and are not necessarily drawn to scale.

[0042] Although relative terms such as "top" and "bottom" are used in this specification to describe the relative position of one component to another, these terms are used for convenience only, e.g., in accordance with the exemplary orientation shown in the drawings. When the device is inverted so that it is upside down, a top component becomes a bottom component. When a structure is described as being "on top" of another structure, this may mean that the structure is integrally formed with the other structure, or that the structure is placed "directly" on top of the other structure, or that the structure is placed "indirectly" on top of the other structure via another structure.

[0043] The terms "a," "the," "said," and "at least one" are used to indicate the presence of one or more elements / components / etc. The terms "comprise" and "comprise" are used to indicate an open-ended meaning and imply that additional elements / components / etc. may be present in addition to the listed elements / components / etc. The terms "first," "second," and "third," etc., are used solely as labels and do not limit the number of objects to which they refer.

[0044] In this application, the term "connection" should be understood in its broadest sense unless explicitly defined and limited otherwise. The term "connection" may, for example, be a fixed connection, a detachable connection, or an integral construction; it may be a direct connection or an indirect connection via an intermediate medium. The term "and / or" simply describes the relationship between connected objects and indicates that there can be three types of relationships. For example, the expression "A and / or B" may mean the presence of A alone, the coexistence of A and B, or the presence of B alone. Furthermore, in this application, the symbol " / " generally denotes an "or" relationship between the objects connected by this symbol.

[0045] An exemplary embodiment of the present disclosure provides a display panel. As shown in Fig. 1 to Fig. 25, the display panel may include a display substrate 100, a touch control layer group 5, and a shield layer 7. The display substrate 100 may include a first electrode 31. The touch control layer group 5 is located on the light-emitting side of the display substrate 100. The touch control layer group 5 includes a touch control body part 61 and a touch control lead wire 62. The touch control lead wire 62 is connected to the touch control body part 61. The shield layer 7 is located between the first electrode 31 and the touch control layer group 5. The shield layer 7 includes a shield body part 71 and a shield lead wire 72. The shield lead wire 72 is connected to the shield body part 71. The width of the shield lead wire 72 is greater than the width of the touch control lead wire 62.

[0046] It should be noted that in the present description, the first direction X intersects the second direction Y. For example, the first direction X and the second direction Y may be perpendicular to each other. Both the first direction X and the second direction Y are parallel to a side of the display substrate 100 facing the touch control layer group 5.

[0047] As in Fig. As shown in Figure 1, the display panel may include a display area AA for displaying images and a non-display area NA that does not display images, wherein a touch control function may be implemented in the display area AA. The non-display area NA may include a side area CB that may be arranged to surround the display area AA. The display panel may further include a bending area BEND for bending and a binding area BOD for binding. The bending area BEND is connected to the side area CB, and the binding area BOD is connected to the bending area BEND.

[0048] The side region CB may include a first side region CB1, a second side region CB2, a third side region CB3, and a fourth side region CB4. The first side region CB1 and the second side region CB2 are located on two opposite sides of the display region AA in the first direction X. The third side region CB3 and the fourth side region CB4 are located on two opposite sides of the display region AA in the second direction Y. The binding region BOD is located on a side of the fourth side region CB4 facing away from the display region AA. In particular, the bending region BEND is connected to the fourth side region CB4, and the binding region BOD is connected to the bending region BEND. That is, the bending region BEND is connected between the binding region BOD and the fourth side region CB4.

[0049] As in Fig. 2, the display panel can be bent in the bending area BEND such that the binding area BOD is bent on a side of the display area AA facing away from a display surface.

[0050] As in Fig. 1, Fig. 4, Fig. 6 and Fig. 7, a bonding pin 273 is provided in the bonding area BOD, to which external devices can be mounted (or attached). The external device can be a display driver chip 10, a touch control driver chip 12, a flexible printed circuit board 11, or a rigid printed circuit board, etc. In addition, chip-on-flex films (Chip On Flex, or Chip On Film, COF), connectors, and the like can also be mounted on the bonding pin 273 as external devices. One or more external devices can be mounted in the bonding area BOD. The display driver chip 10 can be arranged in the bonding area BOD of the display panel, and a printed circuit board can be attached to the end of the bonding area BOD. In this case, the display panel can include a bonding pin connected to the display driver chip 10 and a bonding pin connected to the printed circuit board.In another embodiment, the display driver chip 10 may be mounted on a chip-on-flex film, and the chip-on-flex film may be attached to the bonding area BOD of the display panel.

[0051] As in Fig. As shown in Figure 1, the display driver chip 10 can be mounted on a surface of the display panel that is on the same side as the display surface. The touch control driver chip 12 can be mounted on a surface of the flexible printed circuit board 11 that is on the same side as the display surface. As shown in Fig. As shown in Figure 2, when the bending area BEND is bent in the reverse direction, the display driver chip 10 and the touch control driver chip 12 are positioned on a side of the display panel facing away from the display surface. The touch control driver chip 12 can be bonded to the flexible circuit board 11 using an anisotropic conductive adhesive, or it can be attached to the flexible circuit board 11 using ultrasonic bonding.

[0052] The touch control driver chip 12 may include an integrated circuit that drives the touch control layer group 5. The touch control driver chip 12 may further include an integrated circuit that receives touch control signals. In the exemplary embodiment, the integrated circuit may be a touch control integrated circuit that generates and provides touch control drive signals, as well as a touch control integrated circuit that receives touch control signals, but the present invention is not limited thereto. The touch control driver chip 12 is connected to the bonding pin 273 of the display panel to provide touch control drive signals to the bonding pin 273 and to receive touch control sensor signals fed back from the touch control layer group 5.

[0053] As in Fig. 3, the display panel may include a display substrate 100, which may include a base substrate 1, a driver backplane 2, and a light-emitting substrate 3. The driver backplane 2 is disposed on one side of the base substrate 1, and the light-emitting substrate 3 is disposed on a side of the driver backplane 2 remote from the base substrate 1. A touch control layer group 5 may be provided on the light-emitting side of the display substrate 100. That is, the touch control layer group 5 is disposed on a side of the light-emitting substrate 3 remote from the base substrate 1. A polarizing film 8 may be disposed on a side of the touch control layer group 5 remote from the display substrate 100, and a cover plate 9 may be disposed on a side of the polarizing film 8 remote from the display substrate 100.

[0054] The display substrate 100 may be an OLED (Organic Electroluminescence Display, organic light-emitting diode) display substrate 100, a QLED (Quantum Dot Light Emitting Diode) display substrate 100, etc. The display substrate 100 has a light-emitting side and a non-light-emitting side, with the light-emitting side and the non-light-emitting side arranged opposite each other. Images can be displayed on the light-emitting side, with the side displaying images being the display surface. The OLED display substrate 100 has characteristics such as self-luminescence, high brightness, wide viewing angle, fast response time, and the ability to produce all color components of R, G, and B, and is therefore considered a star product of the next generation of displays.

[0055] To illustrate this, OLED is now taken as an example.

[0056] As in Fig. 3, the driver backplane 2 may include a plurality of drive circuits arranged in an array, and the light-emitting substrate 3 may include a plurality of light-emitting devices arranged in an array, wherein the drive circuits may drive the light-emitting devices to emit light.

[0057] The display substrate 100 may include a base substrate 1. The material of the base substrate 1 may include inorganic materials. For example, such inorganic materials may be glass, quartz, or metals, etc. The material of the base substrate 1 may also include organic materials. For example, such organic materials may be resin materials such as polyimide, polycarbonate, polyacrylate, polyetherimide, polyethersulfone, polyethylene terephthalate, and polyethylene naphthalate. The base substrate 1 may be formed from multiple material layers. For example, the base substrate 1 may include multiple substrate layers, and the material of the substrate layers may be any of the above-mentioned materials. Of course, the base substrate 1 may also consist of a single layer, which may be made of any of the above-mentioned materials.

[0058] As in Fig. As shown in Figure 3, a light-shielding layer 21 may also be disposed on one side of the base substrate 1. Light irradiated from the base substrate 1 into an active layer generates photogenerated charge carriers in the active layer, which in turn can significantly degrade the characteristics of thin-film transistors, ultimately affecting the display quality of the display device. The light-shielding layer 21 can block the light irradiated from the base substrate 1, thereby preventing degradation of the characteristics of thin-film transistors and deterioration of the display quality of the display device. Depending on the type of thin-film transistor, the light-shielding layer 21 may be omitted.

[0059] A buffer layer 22 can also be formed on a side of the light-shielding layer 21 facing away from the base substrate 1. The buffer layer 22 serves to keep moisture and impurity ions away from the base substrate 1 (particularly organic materials) and to increase the concentration of hydrogen ions for a subsequently formed active layer. The material of the buffer layer 22 is an insulating material that can electrically insulate the light-shielding layer 21 from the active layer. The buffer layer 22 can contain silicon nitride, silicon oxide, or silicon oxynitride. Depending on the type of the base substrate 1 or the process conditions, the buffer layer 22 can be omitted.

[0060] An active layer is disposed on a side of the buffer layer 22 facing away from the base substrate 1. The active layer may include a channel region 231 and conductive portions disposed at both ends of the channel region 231, one of the two conductive portions being a source electrode 232 and the other a drain electrode 233. A gate insulating layer 24 is disposed on a side of the active layer facing away from the base substrate 1, and a gate electrode 25 is disposed on one side of the gate insulating layer 24. A dielectric interlayer 26 is disposed on a side of the gate electrode 25 facing away from the base substrate 1, and through holes connected to the conductive portions are formed in the dielectric interlayer 26.On a side of the dielectric interlayer 26 facing away from the base substrate 1, a first connecting conductor layer 27 is arranged, which may include a source lead wire 271 and a drain lead wire 272 in the display region AA. The source lead wire 271 is connected to the source electrode 232 through a through-hole in the dielectric interlayer 26, and the drain lead wire 272 is connected to the drain electrode 233 through a through-hole in the dielectric interlayer 26. A passivation layer 28 is arranged on a side of the first connecting conductor layer 27 facing away from the base substrate 1, and through-holes are formed in the passivation layer 28, which are connected to the source lead wire 271. The channel region 231, the gate electrode 25, the source electrode 232, and the drain electrode 233 form a thin-film transistor.

[0061] In some further exemplary embodiments of the present disclosure, a planarization layer is arranged on a side of the first interconnect layer 27 facing away from the base substrate 1, and through-holes are also formed in the planarization layer. A second interconnect layer is arranged on a side of the planarization layer facing away from the base substrate 1, which second interconnect layer may include a second source lead wire and / or a second drain lead wire in the display region AA. The second source lead wire and the second drain lead wire are connected to the source lead wire 271 and the drain lead wire 272, respectively, through the through-holes in the planarization layer. Of course, a third interconnect layer, a fourth interconnect layer, etc., may also be arranged as needed.

[0062] It should be noted that the thin-film transistors illustrated in the present specification are top-gate type thin-film transistors. In other exemplary embodiments of the present disclosure, the thin-film transistors may also be bottom-gate or dual-gate type, and the specific structures will not be repeated here. Furthermore, when using thin-film transistors with opposite polarities or when changing the current direction during circuit operation, the functions of the "source electrode 232" and the "drain electrode 233" may sometimes be interchanged. Therefore, in the present specification, the "source electrode 232" and the "drain electrode 233" may be interchanged.

[0063] Continue as in Fig. As shown in Figure 3, a light-emitting substrate 3 is arranged on a side of the passivation layer 28 facing away from the base substrate 1. The light-emitting substrate 3 may include a second electrode 34, a pixel definition layer 32, a light-emitting layer group 33, and a first electrode 31.

[0064] In particular, a second electrode 34 is arranged on a side of the passivation layer 28 facing away from the base substrate 1. The second electrode 34 is connected to the source lead wire 271 of the driver backplane 2 via a through-hole. The second electrode 34 may be an anode (pixel electrode).

[0065] A pixel definition layer 32 is arranged on a side of the second electrode 34 facing away from the base substrate 1. An opening is formed in the pixel definition layer 32, which is connected to the second electrode 34, so that at least a portion of the second electrode 34 is exposed.

[0066] On a side of the pixel definition layer 32 facing away from the base substrate 1, a light-emitting layer group 33 is arranged, with at least a portion of the light-emitting layer group 33 being located within the opening. A first electrode 31, which may be a cathode (common electrode), is arranged on a side of the light-emitting layer group 33 facing away from the base substrate 1. The light-emitting layer group 33 within an opening emits light and thus forms a subpixel 35, such that the orthographic projection of the subpixel 35 onto the display substrate 100 corresponds to the orthographic projection of the light-emitting layer group 33 within the opening onto the display substrate 100. The display substrate 100 may comprise a plurality of subpixels 35.

[0067] The light-emitting layer group 33 may include a hole-injection layer, a hole-transport layer, a light-emitting layer, an electron-transport layer, and an electron-injection layer, which are sequentially stacked. The hole-injection layer is in contact with the second electrode 34, and the electron-injection layer is in contact with the first electrode 31. Of course, in other exemplary embodiments of the present disclosure, the light-emitting layer group 33 may include only a hole-transport layer, a light-emitting layer, and an electron-transport layer. The light-emitting layer group 33 may also have other structures, and its specific structure can be adjusted as needed.

[0068] An encapsulation layer group 4 is arranged on a side of the first electrode 31 facing away from the base substrate 1. The encapsulation layer group 4 can be multilayered and comprise an organic layer 42 and inorganic layers. In particular, the encapsulation layer group 4 can comprise a first inorganic layer 41, an organic layer 42 arranged on a side of the first inorganic layer 41 facing away from the base substrate 1, and a second inorganic layer 43 arranged on a side of the organic layer 42 facing away from the base substrate 1. The materials of the first inorganic layer 41, the organic layer 42, and the second inorganic layer 43 will not be repeated here. Of course, the encapsulation layer group 4 can also comprise more or fewer layers.

[0069] In the present exemplary embodiment, as shown in Fig. 3, a touch control layer group 5 is disposed on a side of the encapsulation layer group 4 facing away from the base substrate 1. The touch control layer group 5 may include a barrier layer 51, a first touch control layer 52, a touch insulation layer 53, a second touch control layer 54, and a protection layer 55. The barrier layer 51 is disposed on a side of the encapsulation layer group 4 facing away from the base substrate 1, and the material of the barrier layer 51 may be a SiNx material. The first touch control layer 52 is disposed on a side of the barrier layer 51 facing away from the base substrate 1, and the first touch control layer 52 may be a Ti / Al / Ti three-layer structure, an ITO / Ag / ITO three-layer structure, and the like.The touch insulating layer 53 is disposed on a side of the first touch control layer 52 facing away from the base substrate 1, and the material of the touch insulating layer 53 may be a SiNx material. The second touch control layer 54 is disposed on a side of the touch insulating layer 53 facing away from the base substrate 1, and the second touch control layer 54 may be a Ti / Al / Ti three-layer structure, an ITO / Ag / ITO three-layer structure, and the like. The protective layer 55 is disposed on a side of the second touch control layer 54 facing away from the base substrate 1, and the material of the protective layer 55 is PI (polyimide). Of course, the materials and structures of the above-mentioned layers are only examples for illustration, and they can also be selected and adjusted as needed.

[0070] Due to the small distance between the display substrate 100 and the touch control layer group 5, significant interference with touch control signals occurs, especially in touch controls with an active stylus 13. The noise signals received by the touch control electrodes may even be stronger than the drive signals received by the active stylus 13. Furthermore, the noise intensities are different at an end of the display panel facing the bonding region BOD and at an end of the display panel facing away from the bonding region BOD.

[0071] As in Fig. 3 and Fig. As shown in Figure 4, the first touch control layer 52 and the second touch control layer 54 are formed as electrically conductive grid structures, that is, the first touch control layer 52 and the second touch control layer 54 are composed of a plurality of second grids formed by a plurality of intertwined second metal wires 613. The second grid is a polygon composed of a plurality of grid lines. A second grid corresponds to a subpixel 35, and the orthographic projection of the subpixel 35 onto the base substrate 1 is located within the orthographic projection of the second grid onto the base substrate 1. This arrangement prevents the grid lines of the second grid from obstructing the light emitted by the subpixel 35, thereby ensuring the display quality of the display panel.

[0072] As in Fig. 4 and Fig. As shown in Figure 5, the electrically conductive mesh structure forms a touch control body part 61. That is, the touch control body part may include a plurality of second metal wires 613, and a plurality of intertwined second metal wires 613 form a plurality of second meshes. The touch control body part 61 may be a mutually capacitive structure. The touch control body part 61 may include a plurality of first touch control units 611 and a plurality of second touch control units 612. Both the first touch control units 611 and the second touch control units 612 also include a plurality of second meshes. The first touch control units 611 and the second touch control units 612 of the metal mesh structure have advantages such as low resistance, small thickness, and fast response speed.

[0073] As in Fig. 4 and Fig. 5, the second touch control unit 612 has a line shape extending in a first direction X. The plurality of second touch control units 612 are sequentially arranged in a second direction Y. The first touch control unit 611 has a line shape extending in the second direction Y. The plurality of first touch control units 611 are sequentially arranged in the first direction X. Each first touch control unit 611 may include a plurality of first touch control electrodes 6111 and first connection parts 6112 arranged sequentially in the second direction Y, wherein the plurality of first touch control electrodes 6111 are arranged spaced from each other, and adjacent first touch control electrodes 6111 are each connected to each other via a first connection part 6112.Each second touch control unit 612 may include a plurality of second touch control electrodes 6121 and second connecting parts 6122 arranged one after another in the first direction X, wherein the plurality of second touch control electrodes 6121 are arranged spaced from each other and adjacent first touch control electrodes 6121 are each connected to each other via a second connecting part 6122.

[0074] In some exemplary embodiments, as in Fig. 4 and Fig. As shown in Figure 5, the first touch control electrode 6111, the second touch control electrode 6121, and the second connection part 6122 are arranged in the same layer and can be formed through a single patterning process. The second touch control electrode 6121 and the second connection part 6122 are integrally formed, while the first connection part 6112 can be arranged on a bridging layer, thus forming a bridging structure. A touch insulation layer 53 is arranged between the first connection part 6112 and the second connection part 6122.

[0075] As in Fig. 5, the second touch control layer 54 may include, for example, the first touch control electrode 6111, the second touch control electrode 6121 (not shown in the figure), and the second connection part 6122, wherein the second touch control electrode 6121 and the second connection part 6122 are connected to each other in the second touch control layer 54 to form an integrated structure. Furthermore, there is a gap between the first touch control electrode 6111 on the one hand and the second touch control electrode 6121 and the second connection part 6122 on the other hand, which gap is formed by a break in the second metal wire 613.The first touch control layer 52 may include a first connecting part 6112 connected to two adjacent first touch control electrodes 6111 through a through hole in the touch insulating layer 53, thereby achieving the objective of connecting a plurality of first touch control electrodes 6111 arranged sequentially in the second direction Y into an integrated structure.

[0076] Since electrical signals must be supplied to the driver backplane 2, and electrical signals must also be supplied to the first touch control electrode 6111, the second touch control electrode 6121, and the second connection part 6122, the first touch control electrode 6111, the second touch control electrode 6121, and the second connection part 6122 are arranged farther away from the driver backplane 2 relative to the first touch control layer 52. The interference of electrical signals between the driver backplane 2 and the first touch control electrode 6111, the second touch control electrode 6121, and the second connection part 6122 is reduced. This ensures the display quality and touch control effect of the display panel.Of course, in some other exemplary embodiments of the present disclosure, the first touch control layer 52 may also include the first touch control electrode 6111, the second touch control electrode 6121, and the second connection part 6122, and the second touch control layer 54 may also include the first connection part 6112.

[0077] In some other exemplary embodiments, the first touch-control electrode 6111, the first connection part 6112, and the second touch-control electrode 6121 are arranged in the same layer and can be formed in a single patterning process. The first touch-control electrode 6111 and the first connection part 6112 are integrally formed, while the second connection part 6122 can be arranged on a bridging layer, thus forming a bridging structure. An insulating layer is arranged between the first connection part 6112 and the second connection part 6122.

[0078] For example, the second touch control layer 54 may include the first touch control electrode 6111, the second touch control electrode 6121, and the first connection part 6112, wherein the first touch control electrode 6111 and the first connection part 6112 are connected to each other in the second touch control layer 54 to form an integrated structure. Furthermore, there is a gap between the second touch control electrode 6121 on the one hand and the first touch control electrode 6111 and the first connection part 6112 on the other hand, which gap is formed by a discontinuity in the metal grid.The first touch control layer 52 may include a second connection part 6122 connected to two adjacent second touch control electrodes 6121 through a fourth through-hole in the touch insulation layer 53, thereby achieving the goal of connecting a plurality of second touch control electrodes 6121 arranged sequentially in the first direction X into an integrated structure. Of course, in some other exemplary embodiments of the present disclosure, the first touch control layer 52 may also include the first touch control electrode 6111, the second touch control electrode 6121, and the first connection part 6112, and the second touch control layer 54 may also include the second connection part 6122.

[0079] In some example embodiments, the first touch-control electrode 6111 and the second touch-control electrode 6121 may have a diamond shape, such as a regular diamond, a horizontally elongated diamond, or a vertically elongated diamond. In some possible implementations, the first touch-control electrode 6111 and the second touch-control electrode 6121 may have a triangular, square, trapezoidal, parallelogram, pentagonal, hexagonal, or any other polygonal shape, and the present disclosure is not limited to any specific shapes.

[0080] As in Fig. As shown in Figure 4, a touch control lead wire 62 is provided in the side region CB. The touch control lead wire 62 may include first touch control lead wires 621 and second touch control lead wires 622 (for clarity, different lead wires are distinguished by different line types in the figure).

[0081] First ends of a portion of the first touch control lead wires 621 are each connected to one end of the first touch control units 611, and second ends of the first touch control lead wires 621 are led to bond pins 273 and connected to the bond pins 273. First ends of another portion of the first touch control lead wires 621 are each connected to the other end of the first touch control units 611, and second ends of the other portion of the first touch control lead wires 621 are led to the bond pins 273 and connected to the bond pins 273.

[0082] If the display panel does not cooperate with an active stylus 13 to achieve touch control, and if touch control can be achieved, for example, by fingers, in some example embodiments, the first touch control electrode 6111 may be a drive electrode and the second touch control electrode 6121 may be a sensor electrode. Alternatively, the first touch control electrode 6111 may be a sensor electrode and the second touch control electrode 6121 may be a drive electrode. A plurality of first touch control units 611 and a plurality of second touch control units 612 form M rows of drive electrodes * N columns of sensor electrodes. That is, they comprise M first touch control units 611 and N second touch control units 612, where M and N are positive integers greater than two.

[0083] As in Fig. As shown in FIG. 4, the first end of the second touch control lead wire 622 is connected to one end of each of the second touch control units 612, and the second end of the second touch control lead wire 622 is led to the bonding pin 273 and connected to the bonding pin 273. This wiring method may also be referred to as 2T1R (the first touch control unit 611 serves as a touch control driver unit, and the second touch control unit 612 serves as a touch control sensor unit). Of course, it may also be 1T2R (the first touch control unit 611 serves as a touch control sensor unit, and the second touch control unit 612 serves as a touch control driver unit).

[0084] It is understood that the first touch control electrodes 6111 are arranged sequentially in the same row in the second direction Y (the length direction of the display area AA). A row of first touch control units 611 includes a relatively large number of first touch control electrodes 6111. A touch control signal is transmitted sequentially along a row of first touch control electrodes 6111, starting from the first touch control electrode 6111 coupled to the first touch control lead wire 621, in the direction away from the first touch control lead wire 621. However, as the transmission distance increases, the touch control signal gradually attenuates.Based on this, when the number of first touch control electrodes 6111 is relatively large, the respective coupling of both ends of the first touch control electrodes 6111 in the same row to the first touch control lead wire 621 can ensure that the touch control signal received by the first touch control electrode 6111 that is farthest from the first touch control lead wire 621 in a row of first touch control electrodes 6111 is not attenuated, thereby ensuring that touch control signals at a plurality of first touch control electrodes 6111 in the same row are substantially the same, which reduces touch control noise.

[0085] In some other exemplary embodiments, it is also possible for the first touch control lead wire 621 to have only one connection type, ie, the first touch control unit 611 is connected to the first touch control lead wire 621 at only one end. This wiring method is referred to as 1T1R.

[0086] Of course, in some other exemplary embodiments of the present disclosure, the second touch control lead wires 622 may be split into two parts. First ends of a part of the second touch control lead wires 622 are each connected to one end of the second touch control units 612, and second ends of the second touch control lead wires 622 are led to bond pins 273 and connected to the bond pins 273. First ends of another part of the second touch control lead wires 622 are each connected to the other end of the second touch control units 612, and second ends of the other part of the second touch control lead wires 622 are led to the bond pins 273 and connected to the bond pins 273.

[0087] This wiring method can also be referred to as 2T2R. This wiring method can ensure that, for a series of touch control electrodes coupled to the touch control lines, the touch control signals received by the touch control electrodes farther from the touch control lines do not differ significantly from the touch control signals received by the touch control electrodes closer to the touch control lines. This helps ensure touch control accuracy on relatively large touchscreens.

[0088] As in Fig. As shown in Figure 6, the touch control principle is as follows: the second touch control electrode 6121 and the first touch control electrode 6111 may form a capacitor C, and a plurality of first touch control electrodes 6111 and a plurality of second touch control electrodes 6121 may form a plurality of capacitors C (e.g., C1, C2, C3, etc.). The positions of the capacitors C within the touch control body part 61 are respectively different. That is, within the coordinate system consisting of the first direction X and the second direction Y, the capacitors C are located at different points. The touch control drive chip 12 sends a touch control drive signal (e.g., a trigger signal) to the first touch control lead wire 621, and the touch control drive signal is transmitted to the first touch control electrode 6111 via the first touch control lead wire 621.At this time, each capacitor C at the above-mentioned different positions each has an initial capacitance value. Since the human body itself is a conductor, when a person's finger touches a certain location on the display panel, the capacitance value of the capacitor C at that location changes. Based on the change in the capacitance value, a corresponding touch control sensor signal (e.g., a reception signal) is received at the second touch control electrode 6121 at that location. The touch control sensor signal at the second touch control electrode 6121 at that location is transmitted to the touch control driver chip 12 via the second touch control lead wire 622 and amplified by an amplifier within the touch control driver chip 12. The capacitance values of the capacitors C at the non-touched locations do not change.Therefore, by determining the capacitance values on the capacitors C, the touch control point can be identified, thereby achieving the touch control function.

[0089] However, when displaying images on the display panel, a predetermined voltage also exists at the first electrode 31 of the display substrate 100, particularly when the displayed image changes, that is, when all the data signals transition from the current line of data signals to the next line of data signals. Since the data lines intersect with the first electrode 31 to form a capacitor, the voltage at the first electrode 31 also changes. Moreover, an encapsulation layer group 4 is arranged between the first electrode 31 and the touch control body part 61, so that the first electrode 31 also forms a parasitic capacitor Cr together with the first touch control electrode 6111 and the second touch control electrode 6121.Therefore, the voltage changes at the first electrode 31 affect the voltages at the first touch control electrode 6111 and the second touch control electrode 6121, thereby generating noise that affects the accuracy of the touch control sensor signal.

[0090] As in Fig. As shown in Figure 7, when the display panel is used in conjunction with the active stylus 13 to implement touch control, the specific structure of the touch control layer group is the same as the structure described above. The difference is that both the first touch control electrode 6111 and the second touch control electrode 6121 serve as sensor electrodes, and the first touch control unit 611 and the second touch control unit 612 divide the display area into coordinate grids; the positions of a plurality of first touch control electrodes 6111 and a plurality of second touch control electrodes 6121 within the touch control body part 61 are different. That is,Within the coordinate system consisting of the first direction X and the second direction Y, the first touch control electrodes 6111 and the second touch control electrodes 6121 are each located at different points.

[0091] The touch control principle is as follows: a drive signal is applied not to the first touch control electrode 6111, but to the active stylus 13. When the active stylus 13 touches a specific location on the display panel, the active stylus 13 forms a first capacitor C1 with the first touch control electrode 6111 and a second capacitor C2 with the second touch control electrode 6121. In addition, a third capacitor C3 is formed between the first touch control electrode 6111 and the second touch control electrode 6121. The first capacitor C1, the second capacitor C2, and the third capacitor C3 together form a capacitive structure.A touch control sensor signal of the capacitive structure is transmitted to the touch control driver chip 12 via the first touch control lead wire 621 and the second touch control lead wire 622, respectively, and amplified by an amplifier within the touch control driver chip 12. No touch control sensor signals are output at non-touch locations. Therefore, by determining which first touch control lead wire 621 and second touch control lead wire 622 the touch control sensor signal is output from, the touch control point can be identified, thereby achieving the touch control function.

[0092] However, when displaying images on the display panel, a predetermined voltage also exists at the first electrode 31 of the display substrate 100, particularly when the displayed image changes, that is, when all the data signals transition from the current line of data signals to the next line of data signals. Since the data lines intersect with the first electrode 31 to form a capacitor, the voltage at the first electrode 31 also changes. Moreover, an encapsulation layer group 4 is arranged between the first electrode 31 and the touch control body part 61, so that the first electrode 31 also forms a parasitic capacitor Cr together with the first touch control electrode 6111 and the second touch control electrode 6121.Therefore, the voltage changes at the first electrode 31 affect the voltages at the first touch control electrode 6111 and the second touch control electrode 6121, generating noise that affects the accuracy of the touch control sensor signal. When the display panel is used in conjunction with the active stylus 13, the noise is particularly prominent. This is because the protocol drive frequency of the active stylus 13 is a fixed frequency or a fixed frequency band. When the noise of the displayed image matches the frequency of the active stylus 13 and the signal strength reaches a certain level, the touch control driver chip 12 cannot distinguish whether the detected signal is a touch control signal or a noise signal.

[0093] In addition, as the data signals transition, all data signals in an entire row change simultaneously. When all data signals in the current row transition from the highest (or lowest) gray level to the lowest (or highest) gray level in the next row, the transition of all data signals affects the voltage change at the first electrode 31, resulting in the largest voltage change at the first electrode 31. When the data signals transition from the voltage of the current row to the voltage of the next row with a mixture of upward and downward changes, the effects on the first electrode 31 are both positive and negative and can cancel each other out to some extent, and the voltage change at the first electrode 31 is reduced compared to the scenario where all signals change in the same direction.

[0094] It should also be noted that the frequency of touch control signal detection is much lower than the frequency of data signal transitions on the display substrate 100. The voltage at the first electrode 31 has a certain recovery time. However, if the voltage change at the first electrode 31 is very large and coincides with the detection of touch control signals, errors can easily occur, leading to a malfunction of the touch control.

[0095] How to continue in Fig. 3, in the present exemplary embodiment, a shield layer 7 is disposed between the first electrode 31 and the touch control layer group 5. The shield layer 7 may include a shield body part 71 and a shield lead wire 72. The shield body part 71 is located in the display area AA. One end of the shield lead wire 72 is connected to the shield body part 71, and the other end of the shield lead wire 72 is connected to the bonding pin 273 in the bonding area BOD. The width of the shield lead wire 72 is greater than the width of the touch control lead wire 62.

[0096] On the one hand, the shielding layer 7 can isolate the first electrode 31 from the touch control layer group 5, thereby reducing the effects of voltage changes at the first electrode 31 on the touch control signals of the touch control layer group 5, thus reducing noise signals. As shown in Fig. As shown in Figure 24, the shield layer 7 forms a fourth capacitor C4 between the first touch-control electrode 6111 and the second touch-control electrode 6121, and a fifth capacitor C5 is formed between the shield layer 7 and the first electrode 31. As long as the signal on the shield layer 7 does not change, the capacitance value of the fourth capacitor C4 also does not change, and no noise signals are generated for the first touch-control electrode 6111 and the second touch-control electrode 6121. On the other hand, the width of the shield lead wire 72 is larger than the width of the touch-control lead wire 62, which means that the shield lead wire 72 is wider, which results in a lower resistance for the shield layer 7 and ensures that the shield layer 7 has a better shielding effect.

[0097] In the present exemplary embodiment, as shown in Fig. 8 and Fig. As shown in Figure 9, the shielding body part 71 is formed as a metal grid structure. That is, the shielding body part 71 may include a plurality of first metal wires 711. The plurality of interwoven first metal wires 711 form a plurality of first grids, each first grid corresponding to a subpixel 35. Furthermore, the subpixel 35 of the display substrate 100 is located within the orthographic projection of the first grid onto the display substrate 100. This prevents the first grid lines from obstructing the light emitted by the subpixels 35, thereby ensuring the display quality of the display panel.

[0098] As in Fig. As shown in Figure 10, the horizontal axis represents time, with the unit being microsecond (µs). The vertical axis represents noise intensity, with the unit being millivolt (mV). In the figure, L1 is the noise curve generated by the first electrode, L2 is the noise curve at the touch control layer group 5 without the shield layer 7, L3 is the noise curve at the touch control layer group 5 with the shield layer 7 made of ITO (indium tin oxide), and L3 is the noise curve at the touch control layer group 5 with the shield layer 7 made of metal. From the figure, it can be seen that the resistance of the shield layer 7 made of ITO material is larger than that of the shield layer 7 made of metal material, and the noise at the touch control layer group 5 with the shield layer 7 made of ITO is larger than the noise at the touch control layer group 5 with the shield layer 7 made of metal.Thus, the lower the resistance of the shielding layer 7, the lower the noise at the touch control layer group 5 and the better the shielding effect.

[0099] As in Fig. 14, the dashed line in the figure represents the edge of the sub-pixel 35, the solid line represents the edge of the shield body part 71, and the dot-dashed line represents the edge of the touch control body part 61. The width of the first metal wire 711 of the shield body part 71 is greater than or equal to the width of the second metal wire 613 of the touch control body part 61. Moreover, the orthographic projection of the second metal wire 613 of the touch control body part 61 onto the base substrate 1 is within the orthographic projection of the first metal wire 711 of the shield body part 71 onto the base substrate 1. That is, the orthographic projection of the second metal wire 613 onto the display substrate 100 is located within the orthographic projection of the first metal wire 711 onto the display substrate 100.This ensures that the resistance of the shielding body part 71 is less than or equal to the resistance of the touch control body part 61, thereby further ensuring the shielding effect of the shielding body part 71.

[0100] In addition, as in Fig. 11, there are no interruptions in the shielding body part 71, so that the shielding body part 71 forms a plurality of resistors R connected in series and in parallel, which further reduces the resistance of the shielding body part 71 and ensures its shielding effect.

[0101] Even if the width of the first metal wire 711 is increased, since the shield body part 71 is located in the display area AA, the increase in the width of the first metal wire 711 is limited so as not to affect the aperture ratio of the subpixel 35. Therefore, the width of the shield lead wire 72 can be set to be larger than the width of the first metal wire 711 to further reduce the resistance of the shielding layer 7 and ensure that the shielding layer 7 has a better shielding effect.

[0102] In the present exemplary embodiment, the shield lead wire 72 is grounded or connected to a constant voltage terminal, with the ground voltage or constant voltage serving as a shield signal. Specifically, the shield lead wire 72 is grounded or connected to the constant voltage terminal via the bonding pin 273, thereby grounding the shield body part 71 or connecting it to a constant voltage terminal. This ensures that the shield body part 71 maintains a zero voltage or a constant voltage. Even if the voltage at the first electrode 31 changes, this has no influence on the voltage at the shield body part 71 and, consequently, no influence on the voltage at the touch control body part 61.This prevents noise from being generated at the touch control body part 61 when the voltage at the first electrode 31 changes, which could impair the touch control effect. The constant voltage can be provided by the touch control driver chip 12. That is, the shield lead wire 72 is connected to the touch control driver chip 12 via the bonding pin 273.

[0103] In some other embodiments of the present disclosure, a signal generator may also supply a shielding signal opposite to the noise signal to the shielding layer 7. Specifically, since the direction of change of the cathode signal at the first electrode 31 is the same as the direction of change of the data signals on the data lines, and data signals are easy to measure while cathode signals are not easy to measure, and the noise signal is generated due to the change of the cathode signal at the first electrode 31, the signal generator supplies a shielding signal opposite to the data signal of the display substrate 100 to the shielding layer 7, and the amplitude of the shielding signal is smaller than the amplitude of the data signal. The amplitude of the shielding signal is 20%-40% of the amplitude of the data signal. For example, if the amplitude of the data signal is 5V, the amplitude of the shielding signal is 1V-2V, which is 1.2V, 1.5V, 1.7V, etc.When the cathode signal at the first electrode 31 changes, the shielding signal at the shielding layer 7 also changes, but in the opposite direction and with substantially the same amplitude, so that the voltage at the shielding layer 7 actually does not change, thereby not affecting the signals of the touch control layer. The signal generator may be the touch control driver chip 12. That is, the shielding lead wire 72 is connected to the touch control driver chip 12 via the bonding pin 273, and the touch control driver chip 12 supplies a shielding signal opposite to the data signal of the display substrate 100 to the shielding layer 7, thereby further improving the shielding effect.

[0104] It is understood that a shielding signal is transmitted sequentially along the shielding body part 71 from an end of the shielding body part 71 coupled to the shielding lead wire 72 in the direction away from the shielding lead wire 72. However, as the transmission distance increases, the shielding signal gradually attenuates. Based on this, when the shielding body part 71 is relatively long, both ends of the shielding body part 71 are respectively coupled to the shielding lead wire 72, thereby ensuring that the part of the shielding body part 71 farthest from the shielding lead wire 72 can receive the shielding signal.This ensures that the shielding signals in different parts of the shielding body part 71 are substantially the same, thereby maintaining a uniform shielding effect across all parts of the shielding body part 71 and ensuring the shielding effect.

[0105] However, if the resistances of the shield lead wires 72 connected to both ends of the shield body part 71 are different, this also causes the shield signals input to both ends of the shield body part 71 to be different, resulting in uneven shielding effects and thus deteriorating the shielding effect.

[0106] Even if the resistances of the shield lead wires 72 connected to the same end of the shield body part 71 are different, this also causes the shield signals input to the same end of the shield body part 71 to be different, resulting in uneven shielding effects and thus deteriorating the shielding effect.

[0107] To solve the above problem, it is important that when at least two shield lead wires 72 are provided, the resistances of the at least two shield lead wires 72 are identical. This avoids the noise caused by the different resistances of the shield lead wires 72, namely, the inconsistency of the shield signals input to both ends of the shield body part 71 due to the different resistances of the shield lead wires 72 is avoided, thereby avoiding the inconsistency of the shielding effect and ensuring the shielding effect.

[0108] It should be noted that identical resistances do not mean that the resistances are absolutely identical, but allow for some margin for error. Depending on the equipment and manufacturing process, the tolerance range may vary. Therefore, as long as the resistances are within the allowable tolerance range for the equipment and manufacturing process, the resistances are assumed to be identical. For example, if the resistance of one shield lead wire 72 is 95% to 105% of the resistance of another shield lead wire 72, the resistances of the two shield lead wires 72 are assumed to be identical.

[0109] In some exemplary embodiments, as in Fig. 8, a bonding region BOD may be provided, which is located on one side of the display region AA in the second direction Y. The bonding region BOD is provided with at least two bonding pins 273. The shield lead wire 72 may include a first lead wire 721 and a second lead wire 722. The first lead wire 721 is connected at one end to the bonding pins 273 and at the other end to an end of the shield body part 71 facing away from the bonding region BOD. The second lead wire 722 is connected at one end to the bonding pins 273 and at the other end to an end of the shield body part 71 facing the bonding region BOD. The resistance of the second lead wire 722 is equal to the resistance of the first lead wire 721.

[0110] Since the first lead wire 721 is longer and the second lead wire 722 is shorter, and the length of the first lead wire 721 cannot be shortened, the resistance of the first lead wire 721 can be increased by lengthening the second lead wire 722, thereby achieving the goal of making the resistance of the second lead wire 722 equal to that of the first lead wire 721. Of course, it is also possible to reduce the resistance of the second lead wire 722 by increasing its width or thickness to achieve the goal of making the resistance of the second lead wire 722 equal to that of the first lead wire 721. The thickness of the second lead wire 722 can be increased either by thickening a single layer or by providing two layers. That is,The second lead wire 722 may be implemented as a two-layer structure, one layer of which is arranged in the same layer and made of the same material as the first electrode 31. Of course, the layer may also be arranged in the same layer and made of the same material as the source lead wire 271, the second electrode 34, the first touch control layer 52, or the second touch control layer 54.

[0111] In some other exemplary embodiments, as in Fig. 9, two bonding regions BOD may be provided, which may be a first bonding region BOD1 and a second bonding region BOD2, located on two opposite sides of the display region AA in the second direction Y. The shield lead wire 72 may include a first lead wire 721 and a second lead wire 722. The first lead wire 721 is connected at one end to the bonding pins 273 of the first bonding region BOD1 and at the other end to an end of the shield body part 71 facing the first bonding region BOD1. The second lead wire 722 is connected at one end to the bonding pins 273 of the second bonding region BOD2 and at the other end to an end of the shield body part 71 facing the second bonding region BOD2.

[0112] Therefore, since the first lead wire 721 is arranged only in the fourth side region CB4 and can connect the shield body part 71 and the bonding pin 273 without providing other side regions CB, and the second lead wire 722 is arranged only in the third side region CB3 and can connect the shield body part 71 and the bonding pin 273 without providing other side regions CB, it is possible to make the resistance of the second lead wire 722 equal to that of the first lead wire 721 by making the length, width, and thickness of the second lead wire 722 equal to the length, width, and thickness of the first lead wire 721, respectively.

[0113] In addition, the lengths of the first lead wire 721 and the second lead wire 722 in the present exemplary embodiment are shorter than the resistances of the first lead wire 721 and the second lead wire 722 in the present exemplary embodiment of Fig. 8. Therefore, the resistances of the first lead wire 721 and the second lead wire 722 in the present exemplary embodiment are smaller than the resistances of the first lead wire 721 and the second lead wire 722 in the present exemplary embodiment of Fig. 8, which leads to a better shielding effect of the shielding body part 71.

[0114] It should be noted that one, two or more first connecting wires 721 may be provided as long as there is sufficient space in the side region CB to provide the first connecting wires 721; that one, two or more second connecting wires 722 may also be provided as long as there is sufficient space in the side region CB to provide the second connecting wires 722.

[0115] In addition, the length of the display area AA in the second direction Y is Fig. 8 and Fig. 9 is greater than the width of the display area AA in the first direction X. When the length of the display area AA in the first direction X is greater than the width of the display area AA in the second direction Y in some other exemplary embodiments of the present disclosure, the bonding area BOD may be arranged on one side of the display area AA in the second direction Y. That is, the bonding area BOD is located on one side of the display area AA in the width direction. Alternatively, the first bonding area BOD1 and the second bonding area BOD2 may be arranged on two opposite sides of the display area AA in the second direction Y. That is, the first bonding area BOD1 and the second bonding area BOD2 are located on one side of the display area AA in the width direction. The formation of the first lead wire 721 and the second lead wire 722 follows the structural layout in Fig. 8 and Fig. 9. The specific structure of the first connecting wire 721 and the second connecting wire 722 has been described in detail above and will therefore not be repeated here.

[0116] In some further exemplary embodiments, as in Fig. 8 and Fig. As shown in Figure 9, the shield lead wire 72 may also include a third lead wire 723 and a fourth lead wire 724. The third lead wire 723 is connected at one end to the bonding pin 273 and at the other end to an end of the shield body part 71 facing the first side region CB1. The fourth lead wire 724 is connected at one end to the bonding pin 273 and at the other end to an end of the shield body part 71 facing the second side region CB2.

[0117] As in Fig. 12, for example, when a bonding region BOD is provided, the third lead wire 723 may be led from the first side region CB1 to the fourth side region CB4 and then connected to the bonding pin 273, and the fourth lead wire 724 may be led from the second side region CB2 to the fourth side region CB4 and then connected to the bonding pin 273.

[0118] As in Fig. As shown in Figure 13, when two bonding regions BOD are provided, the third lead wire 723 near the first bonding region BOD1 may be routed from the first side region CB1 to the fourth side region CB4 and then connected to the bonding pin 273 of the first bonding region BOD1. The third lead wire 723 near the second bonding region BOD2 may be routed from the first side region CB1 to the third side region CB3 and then connected to the bonding pin 273 of the second bonding region BOD2. The fourth lead wire 724 near the first bonding region BOD1 may be routed from the second side region CB2 to the fourth side region CB4 and then connected to the bonding pin 273 of the first bonding region BOD1.The fourth connecting wire 724 near the second bonding region BOD2 can be led from the second side region CB2 to the third side region CB3 and then connected to the bonding pin 273 of the second bonding region BOD2.

[0119] The third connecting wire 723 and the fourth connecting wire 724 may be arranged symmetrically to ensure that the resistance of the third connecting wire 723 corresponds to the resistance of the fourth connecting wire 724.

[0120] It should be noted that one, two, or more third connecting wires 723 may be provided, as long as there is sufficient space in the side region CB to provide the third connecting wires 723; that one, two, or more fourth connecting wires 724 may also be provided, as long as there is sufficient space in the side region CB to provide the fourth connecting wires 724.

[0121] Furthermore, when two or more third connecting wires 723 are provided, their resistances can be made equal by making the lengths of the two or more third connecting wires 723 equal. Their resistances can also be made equal by adjusting the widths or thicknesses of the third connecting wires 723. When two or more fourth connecting wires 724 are provided, their resistances can also be made equal by making the lengths of the two or more fourth connecting wires 724 equal. Their resistances can also be made equal by adjusting the widths or thicknesses of the fourth connecting wires 724.

[0122] It should be noted that the third lead wire 723 and the fourth lead wire 724 can be provided on the basis of the first lead wire 721 and the second lead wire 722, which means that the first lead wire 721, the second lead wire 722, the third lead wire 723, and the fourth lead wire 724 are arranged on one display panel at the same time. The third lead wire 723 and the fourth lead wire 724 can be arranged separately on the display panel, which means that one display panel simultaneously includes the third lead wire 723 and the fourth lead wire 724, but does not include the first lead wire 721 and the second lead wire 722.

[0123] As in Fig. 15, Fig. 19 and Fig. 20, the shielding layer 7 may also include a shielding connecting part 73 that can be arranged around the periphery of the shielding body part 71 and connected thereto. That is, the shielding connecting part 73 may be arranged around the shielding body part 71. The shielding connecting part 73 may connect the outermost ends of the first metal wires 711 of the shielding body part 71 to each other. The shielding lead wire 72 is connected to the shielding connecting part 73, so that the shielding signal is transmitted via the shielding lead wire 72 to the shielding connecting part 73 and then via the shielding connecting part 73 to the shielding body part 71, thereby ensuring the uniformity of the individual shielding signals throughout the shielding body part 71.

[0124] The shield connection part 73 is arranged in the non-display area NA. Therefore, the shield connection part 73 can be formed as a metal plate without the need to provide a grid structure for escaping subpixels 35 at the shield connection part 73, which further reduces the resistance of the shield layer 7 and ensures the shielding performance.

[0125] Furthermore, the width of the shield connection part 73 is larger than the width of the touch control lead wire 62, so the resistance of the shield connection part 73 is smaller, thereby reducing the resistance of the shielding layer 7 and ensuring shielding performance. Furthermore, the orthographic projection of the touch control lead wire 62 onto the display substrate 100 overlaps with the orthographic projection of the shield connection part 73 onto the display substrate 100. Specifically, the orthographic projection of the touch control lead wire 62 arranged around the periphery of the touch control body part 61 onto the display substrate 100 is within the orthographic projection of the shield connection part 73 onto the display substrate 100.However, since the touch control lead wire 62 must extend to the bonding region BOD to be connected to the bonding pin 273, the orthographic projection of a part of the touch control lead wire 62 extending toward the bonding region BOD does not overlap with the orthographic projection of the shield connection part 73 onto the display substrate 100. The shield connection part 73 can shield the touch control lead wire 62, thereby preventing the signal of the first electrode 31 from affecting the signal of the touch control lead wire 62, thereby further reducing noise on the touch control layer group 5.

[0126] Continue as in Fig. 16 and Fig. 19, the display panel may also include a noise suppression layer 16. The orthographic projection of the noise suppression layer 16 onto the display substrate 100 overlaps with the first electrode 31. The orthographic projection of the noise suppression layer 16 onto the display substrate 100 is located on a side of the orthographic projection of the shielding layer 7 onto the display substrate 100, facing away from the display area AA. That is, the noise suppression layer 16 is arranged on the outer periphery of the shielding layer 7.

[0127] The display panel may also include a signal generator that can be connected to the noise suppression layer 16. The signal generator can be used to supply the noise suppression layer 16 with a noise suppression signal that opposes the transition of the data signal. The noise suppression signal is an alternating current signal. The signal generator can be the display driver chip 10. That is, the noise suppression signal can be calculated and output by the display driver chip 10.

[0128] The amplitude ΔVsl of the noise suppression signal is given by the formula ΔVsl=-Cd*ΔVd / Csl, where Cd is the capacitance formed between all data lines 15 and the first electrode 31, ΔVd is the average voltage transition of the data signal on the data lines 15, and Csl is the capacitance formed between the first electrode 31 and the noise suppression layer 16. Therefore, the magnitude of the amplitude of the noise suppression signal is determined by the capacitance formed between all data lines 15 and the first electrode 31 and the capacitance formed between the first electrode 31 and the noise suppression layer 16. The above amplitude is theoretical. Due to errors in processes, equipment, etc., the amplitude of the noise suppression signal will vary between different products.The amplitude of the noise suppression signal can be tested on actual products and then adjusted with specific compensations. The noise suppression layer 16 can actively reduce the amplitude of the noise at the first electrode 31, thereby reducing the effects of voltage transients at the first electrode 31 on the touch control layer group 5 and thus reducing the noise at the touch control layer group 5.

[0129] Furthermore, it can be deduced from the above formula that the capacitance formed between the noise suppression layer 16 and the first electrode 31 is inversely proportional to the amplitude of the noise suppression signal. Therefore, the larger the capacitance value of the capacitance formed between the noise suppression layer 16 and the first electrode 31, the more favorable it is for reducing the amplitude of the noise at the first electrode 31. The larger the overlap area between the noise suppression layer 16 and the first electrode 31, the larger the capacitance formed between the noise suppression layer 16 and the first electrode 31, and the better the shielding effect. Therefore, within permissible limits, it is advantageous to make the area of the noise suppression layer 16 large.

[0130] As in Fig. As shown in Figure 17, the data signal causes a voltage transition at the first electrode 31 during a transition, generating noise in the form of sharp peaks and valleys. Upon input of a noise suppression signal on the noise suppression layer 16 that is opposite to the data signal transition, this noise suppression signal also causes a voltage transition at the first electrode 31. However, the direction of this voltage transition is opposite to the direction of the noise jump. Consequently, some of the noise is canceled, reducing the overall noise level.

[0131] The specific configuration of the noise suppression layer 16 is as follows: The noise suppression layer 16 can be arranged in the same layer and made of the same material as the shielding layer 7. That is, the noise suppression layer 16 and the shielding layer 7 are arranged in the same layer and made by the same patterning process.

[0132] Furthermore, in some other exemplary embodiments of the present disclosure, the noise suppression layer 16 may be arranged in the same layer and made of the same material as the first connection conductor layer 27, which may also actively reduce the amplitude of the noise at the first electrode 31, thereby reducing the effects of voltage transients at the first electrode 31 on the touch control layer group 5 and thus reducing the noise at the touch control layer group 5. That is, the noise suppression layer 16 may be arranged in the same layer and manufactured by the same patterning process as the source lead wire 271 and the drain lead wire 272. As in Fig. 18, when the display substrate 100 also includes a second interconnection layer 29, it is understood that the noise suppression layer 16 may be disposed in the same layer and made of the same material as the second interconnection layer 29. That is, the noise suppression layer 16 may be disposed in the same layer and made by the same patterning process as the second source lead wire and the second drain lead wire. The noise suppression layer 16 may also be disposed in the same layer and made of the same material as the first interconnection layer 27. That is, the noise suppression layer 16 may be disposed in the same layer and made by the same patterning process as the source lead wire 271 and the drain lead wire 272.If the display substrate 100 also includes a third interconnect layer and a fourth interconnect layer, the noise suppression layer 16 can be arranged in the same layer and made of the same material as the third interconnect layer and the fourth interconnect layer. That is, the noise suppression layer 16 can be arranged in the same layer and made by the same patterning process as the third source lead wire and the third drain lead wire or the fourth source lead wire and the fourth drain lead wire.

[0133] It should be noted that when at least two interconnection layers are provided, that is, when the interconnection layers include the above-mentioned first interconnection layer 27 and the above-mentioned second interconnection layer 29, the noise suppression layer 16 is arranged in the same layer and made of the same material as the interconnection layer closest to the first electrode 31. For example, when the display substrate 100 also includes a second interconnection layer 29 arranged on a side of the first interconnection layer 27 facing away from the base substrate 1, the noise suppression layer 16 can be arranged in the same layer and made of the same material as the second interconnection layer 29.If the display substrate 100 also includes a third interconnection layer disposed on a side of the second interconnection layer 29 facing away from the base substrate 1, the noise suppression layer 16 may be disposed in the same layer and made of the same material as the third interconnection layer.

[0134] As a result, the noise suppression layer 16 is located in close proximity to the first electrode 31, so that the capacitance between the noise suppression layer 16 and the first electrode 31 is larger, which improves the noise suppression effect of the noise suppression layer 16.

[0135] As in Fig. 19 and Fig. 20, it can be seen from the figures that the width of the shield lead wire 72 substantially corresponds to the width of the first power supply lead wire 14, and the width of the data line 15 substantially corresponds to the width of the first touch control lead wire 621 and the width of the second touch control lead wire 622. Furthermore, the width of the shield lead wire 72 is significantly larger than the width of the first touch control lead wire 621. The width of the shield lead wire 72 may, for example, be more than five times the width of the first touch control lead wire 621 and should be made as large as possible if the framework permits.

[0136] As in Fig. 19, the bonding pin of the noise suppression layer 16 is arranged outside the first power supply lead wire.

[0137] It should be noted that the Fig. 19 and Fig. The number of shield lead wires 72, first power supply lead wires 14, data lines 15, first touch control lead wires 621, and second touch control lead wires 622 indicated in FIG. 20 is merely exemplary and does not limit the present disclosure. The specific number can be adjusted as needed.

[0138] The shielding layer 7 can be arranged between the film layers of the encapsulation layer group 4. In particular, the shielding layer 7 can be arranged as shown in Fig. 21, between the first inorganic layer 41 and the organic layer 42, or, as shown in Fig. 22, the shielding layer 7 may be arranged between the organic layer 42 and the second inorganic layer 43.

[0139] As in Fig. 3, the shielding layer 7 can also be arranged on a side of the encapsulation layer group 4 facing away from the base substrate 1. That is, the shielding layer 7 can also be arranged between the encapsulation layer group 4 and the touch control layer group 5.

[0140] Furthermore, when the shielding layer 7 is disposed at different locations, that is, when the shielding layer 7 is disposed between different film layers, the width of the first metal wire 711 of the shielding layer 7 may vary. Specifically, the width of the first metal wire 711 of the shielding layer 7 decreases with increasing distance from the light-emitting substrate 3. The closer the shielding layer 7 is to the light-emitting substrate 3, the shorter the distance between the shielding layer 7 and the subpixel 35, resulting in a smaller scattering area for the light emitted from the subpixel 35. Therefore, the width of the first metal wire 711 of the shielding layer 7 may be made wider to ensure that the shielding layer 7 does not obstruct the light emitted from the subpixel 35 and does not impair the light emission efficiency of the display panel.Furthermore, this design results in lower resistance of the shielding layer 7 and a better shielding effect. For example, the width of the first metal wire 711 of the shielding layer 7 in . Fig. 3 smallest, in Fig. 21 largest and in Fig. 22 a medium width.

[0141] The width of the first metal wire 711 is greater than or equal to 5 micrometers and less than or equal to 25 micrometers. The width of the shield lead wire 72 is greater than or equal to 200 micrometers.

[0142] The shielding layer 7 may include a first conductive layer, a second conductive layer, and a third conductive layer arranged one above the other. The materials of the first conductive layer and the third conductive layer may be titanium (Ti), and the material of the second conductive layer may be aluminum (Al). This means that the shielding layer 7 may have a TiAlTi laminate structure. Of course, the shielding layer 7 may also have a laminate structure of Mo / Al / Mo, Mo / AlGe / Mo, or Ti / Cu. The shielding layer 7 may also be a single-layer metal structure.

[0143] The material of the shielding layer 7 can also be a transparent conductive material. In this case, the shielding body part 71 is implemented as a single layer. This means that no grid holes associated with the subpixels 35 need to be provided in the shielding main body 71. The light emitted by the subpixels 35 can pass directly through the transparent conductive material.

[0144] Furthermore, the material of the touch control body part 61 can also be a transparent conductive material. In this case, the touch control body part 61 is implemented as a single layer. This means that no grid holes associated with the subpixels 35 need to be provided in the touch control body part 61. The light emitted by the subpixels 35 can pass directly through the transparent conductive material.

[0145] The touch control lead wire 62, the shield lead wire 72, the data line 15, and the first power supply lead wire 14 must all be connected to other external devices in the bonding area BOD. Specifically, the touch control lead wire 62 extends to the bonding area BOD and forms a touch control bond pin 623 in the bonding area BOD. The shield lead wire 72 extends to the bonding area BOD and forms a shield bond pin 725 in the bonding area BOD. The data line 15 extends to the bonding area BOD and forms a data bond pin 151 in the bonding area BOD. The first power supply lead wire 14 extends to the bonding area BOD and forms a first power supply bond pin 141 in the bonding area BOD.At least one layer of the touch control bond pin 623, the shield bond pin 725, the data bond pin 151, and the first power supply bond pin 141 is arranged in the same layer and is made of the same material. This configuration ensures that all bond pins are arranged in the same layer with the same height, which facilitates bonding and leads to better bond quality.

[0146] As in Fig. 25 and Fig.As shown in Figure 26, the data line 15 extends to the bonding region BOD and forms a data bonding pin 151 in the bonding region BOD. The data bonding pin 151 may include a first layer 1511, a second layer 1512, and a third layer 1513. The first layer 1511 is a part of the data line 15 that extends to the bonding region BOD. The second layer 1512 is arranged in the same layer and is made of the same material as the shield lead wire 72. The second layer 1512 is not connected to the shield lead wire 72, but is separate from it. The third layer 1513 is arranged in the same layer and is made of the same material as the touch control lead wire 62.

[0147] The touch control bonding pin 623 may include the above-mentioned three layers. However, the first layer 1511 of the touch control bonding pin 623 is not connected to the data line 15, but is separated from it, and is only arranged in the same layer and made of the same material as the data line 15. The second layer 1512 of the touch control bonding pin 623 is also arranged in the same layer and made of the same material as the shield lead wire 72, and is not connected to the shield lead wire 72, but is separated from it. Of course, the touch control bonding pin 623 may include only a single layer, namely a portion extending from the touch control lead wire 62 to the bonding region BOD.

[0148] The shield bonding pin 725 may include the above-mentioned three layers. However, the first layer 1511 of the shield bonding pin 725 is not connected to the data line 15, but is separated from it, and is only arranged in the same layer and made of the same material as the data line 15. The third layer 1513 of the shield bonding pin 725 is not connected to the touch control lead wire 62, but is separated from it, and is only arranged in the same layer and made of the same material as the touch control lead wire 62. Of course, the shield bonding pin 725 may also include a part extending from the shield lead wire 72 to the bonding region BOD and the above-mentioned third layer 1513.

[0149] The first power supply bonding pin 141 may include the above-mentioned three layers. The first power supply lead wire 14 may be connected to any of the three layers by a bridging method. However, the first layer 1511 of the first power supply bonding pin 141 is not connected to the data line 15, but is separated from it, and is only arranged in the same layer and made of the same material as the data line 15. The second layer 1512 of the first power supply bonding pin 141 is also arranged in the same layer and made of the same material as the shield lead wire 72, and is not connected to the shield lead wire 72, but is separated from it.The third layer 1513 of the first power supply bonding pin 141 is not connected to the touch control lead wire 62, but is separate from it, and is only arranged in the same layer and made of the same material as the touch control lead wire 62. Furthermore, each of the three layers can be replaced by a portion extending from the first power supply lead wire 14 to the bonding region BOD.
