[0022] It will be understood that when a layer or an element is referred to as being on another layer or substrate, it can be directly on the other layer or substrate, or intervening layers may be present between the layer or element and the other layer or substrate.

[0023] Organic Light-Emitting Display (OLED) display panels have become the mainstream development direction in the field of display technology due to their advantages of self-luminescence, high brightness, good image quality, and low energy consumption. By setting a touch screen pane (TSP) in the display panel, touch control of the display panel can be achieved.

[0024] Related Technology In a touch display panel, in order to ensure the touch performance of the touch display panel, it is necessary to continuously monitor the changes in the main capacitance and parasitic capacitance of the display panel. However, in existing touch display panels, the parasitic capacitance of the display panel will continue to change due to the thickness of the dielectric layer in the climbing area, which greatly increases the difficulty of controlling the parasitic capacitance of the display panel.

[0025] In view of this, an embodiment of the present application provides a display panel. Figure 1 FIG. 4 shows a schematic diagram of a film structure of a display panel proposed in an embodiment of the present application. Figure 1As shown, the display panel includes a flat area A1 and a climbing area A2, and the climbing area A2 is arranged around the flat area A1. The display panel includes: a display substrate 11; a touch layer 12, and the touch layer 12 is arranged on the light-emitting side of the display substrate 11; a cathode 13, and the cathode 13 is arranged between the touch layer 12 and the display substrate 11.

[0026] In some optional embodiments, the display substrate 11 may be an organic light emitting diode (OLED) display substrate, a quantum dot light emitting diode (QLED) display substrate, a micro-light emitting diode (Micro-Light Emitting Diode, Micro-LED) display substrate, etc., and the present application does not limit this.

[0027] The following takes the display substrate 11 as an OLED display substrate as an example to schematically illustrate some embodiments of the present application. It is easy to understand that the implementation method of the present application is not limited to this, and it can also be any other display substrate as long as it has the same technical concept.

[0028] In the embodiment of the present application, the thickness of the flat area A1 remains unchanged, the thickness of the climbing area A2 is less than the thickness of the flat area A1, and the thickness of the climbing area A2 gradually decreases along the second direction F2. Therefore, in the flat area A1, the distance between the touch layer 12 and the cathode 13 along the first direction F1 remains unchanged, and in the climbing area A2, the distance between the touch layer 12 and the cathode 13 along the first direction F1 will change. Among them, the first direction F1 is the arrangement direction of the touch layer 12 and the display substrate 11, and the second direction F2 is the direction from the flat area A1 to the climbing area A2. It should be noted that the thickness mentioned in the embodiment of the present application refers to the distance between the two opposite sides of the film layer along the first direction.

[0029] During the operation of the display panel, the client needs to monitor the capacitance changes in the display panel to ensure the touch display performance of the display panel. Specifically, the capacitance in the display panel includes touch capacitance and parasitic capacitance. The touch capacitance is the main capacitance of the display panel, the touch capacitance is the capacitance of the touch layer 12, and the parasitic capacitance is the capacitance formed between the wiring in the touch layer 12 and the cathode 13. For the parasitic capacitance in the display panel, the client refers to it as DTN abnormality (Display to Touch Noise, parasitic capacitance changes between the display film layer and TSP Metal). The principle of the client monitoring parasitic capacitance can be understood as a parallel plate capacitor. Changes in the dielectric constant, distance, and contact area between parallel plates will affect the capacitance of the parallel plate capacitor.

[0030] In the embodiment of the present application, Figure 3 FIG. 1 shows a schematic diagram of the layout design of a first touch line and a second touch line in a touch layer of a display panel proposed in an embodiment of the present application. Figure 3 As shown, the touch layer 12 includes a plurality of first touch lines 121 and a plurality of second touch lines 122 that are cross-arranged. Optionally, the first touch lines 121 are touch receiving lines, and the second touch lines are touch transmitting lines. The touch receiving lines (Rx lines for short) are receiving (Receive) lines for capacitive touch detection, and the touch transmitting lines (Tx lines for short) are transmitting (Transmit) lines for capacitive touch detection. The plurality of first touch lines 121 and the plurality of second touch lines 122 together construct a capacitive detection network of the touch layer 12 of the display panel. Specifically, the multiple first touch lines 121 and the multiple second touch lines 122 of the touch layer 12 intersect with each other to form a series of capacitance nodes. When the user touches the screen, the capacitance at the touch point will change. This change will be captured by the capacitance detection circuits on the multiple first touch lines 121 and the multiple second touch lines 122. By measuring these capacitance changes, the touch system can determine the position of the touch point, thereby achieving a response to the screen touch.

[0031] In some optional embodiments, the plurality of first touch lines 121 are arranged at intervals along the second direction F2, and the plurality of second touch lines 122 are arranged at intervals along a third direction, wherein the third direction is a direction perpendicular to the second direction F2 on the plane where the plurality of first touch lines 121 are located. Figure 3For example, the multiple first touch lines 121 include 32 first touch lines 121 of R0-R31, and the multiple first touch lines 121 are arranged at intervals along the second direction F2; the multiple second touch lines 122 include 15 second touch lines 122 of T0-T14, and the multiple second touch lines 122 are arranged at intervals along the third direction F3.

[0032] Since the thickness of the flat area A1 and the climbing area A2 is different, the distance between the cathode 13 and the touch layer 12 changes, which in turn causes the parasitic capacitance between the touch layer 12 in the climbing area A2 and the cathode 13 to change, affecting the stability of the parasitic capacitance and increasing the difficulty of monitoring the parasitic capacitance. Therefore, in order to improve the stability of the parasitic capacitance between the cathode 13 and the first touch wiring 121, in the embodiment of the present application, the orthographic projections of the plurality of first touch wirings 121 on the display substrate 11 are located in the flat area A1. Since the thickness of the flat area A1 remains unchanged, in the flat area A1, the distance between each first touch wiring 121 and the cathode 13 along the first direction F1 is the same, and the parasitic capacitance between the plurality of first touch wirings 121 and the cathode 13 remains unchanged.

[0033] In addition, since the thickness of the flat area A1 is greater than the thickness of the climbing area A2, if the first touch line 121 is located in the climbing area A2, the parasitic capacitance between the cathode 13 and the first touch line 121 will increase. In the embodiment of the present application, by setting the plurality of first touch lines 121 in the thicker flat area A1, the distance between the plurality of first touch lines 121 and the cathode 13 along the first direction F1 is greater than that in the case of being set in the climbing area A2, thereby effectively reducing the parasitic capacitance in the display panel and improving the touch performance.

[0034] In some optional embodiments, such as Figure 1 As shown, the display panel further includes a blocking dam 111, which is disposed on a side of the climbing area A2 away from the flat area A1, and is configured to block the film layer above the display substrate 11 from overflowing toward the edge of the display substrate 11. The positive projection of the cathode 13 on the display substrate 11 is located on a side of the blocking dam 111 close to the climbing area A2.

[0035] In some optional embodiments, Figure 5 FIG. 4 shows a schematic diagram of a first preset distance between an edge touch line and a barrier dam proposed in an embodiment of the present application. Figure 3 and Figure 5As shown, the multiple first touch lines 121 include an edge touch line 1211, and the edge touch line 1211 is the first touch line 121 closest to the blocking dam 111 among the multiple first touch lines 121. Since the other first touch lines 121 except the edge touch line 1211 are arranged on a side of the edge touch line 1211 close to the flat area A1, as long as the edge touch line 1211 is located in the flat area A1, it can be ensured that the distances between all the first touch lines 121 and the cathode 13 along the first direction F1 are the same.

[0036] In the present application embodiment, Figure 1 As shown, since the flat area A1 and the climbing area A2 are both located on the same side of the blocking dam 111, in the embodiment of the present application, by controlling the distance between the edge touch line 1211 and the blocking dam 111 along the second direction F2, the edge touch line 1211 is made to cross the boundary between the flat area A1 and the climbing area A2, so that the plurality of first touch lines 121 are arranged inside the flat area A1. Specifically, Figure 5 FIG. 4 shows a schematic diagram of a first preset distance between an edge touch line and a barrier dam proposed in an embodiment of the present application. Figure 1 and Figure 5 As shown, the distance between the edge touch line 1211 and the barrier dam 111 along the second direction F2 is a first preset distance d1. Optionally, the first preset distance d1 is greater than or equal to 2500 microns and less than or equal to 3500 microns. Exemplarily, the first preset distance d1 is 3000 microns, and the distance between the edge touch line 1211 and the barrier dam 111 along the second direction F2 is 3000 microns, ensuring that the edge touch line 1211 is located in the flat area A1.

[0037] In some optional embodiments, the display panel further includes an interlayer dielectric layer 14, the thickness difference between the climbing area A2 and the flat area A1 is caused by the profile and thickness of the interlayer dielectric layer 14, and the interlayer dielectric layer 14, the first touch line 121 and the cathode 13 together form the parasitic capacitor. Figure 1 As shown, the interlayer dielectric layer 14 is disposed between the touch layer 12 and the cathode 13, and the orthographic projection of the interlayer dielectric layer 14 on the display substrate 11 is located on the side of the barrier dam 111 close to the climbing area A2. In the climbing area A2, the thickness of the interlayer dielectric layer 14 along the first direction F1 gradually decreases; in the flat area A1, the thickness of the interlayer dielectric layer 14 along the first direction F1 is the same.

[0038] In some optional embodiments, the thickness of the interlayer dielectric layer 14 along the first direction F1 is greater than the thickness of the cathode layer 13 and the touch layer 12 along the first direction F1. Optionally, the thickness of the interlayer dielectric layer 14 along the first direction F1 is greater than or equal to 6 microns and less than or equal to 15 microns. Exemplarily, the thickness of the interlayer dielectric layer 14 along the first direction F1 is 9 microns.

[0039] In some optional embodiments, Figure 2 FIG. 4 shows a schematic diagram of a film layer cross-sectional structure of a display panel proposed in an embodiment of the present application. Figure 2 As shown, the touch layer 12 includes a first touch layer 21 , a touch insulating layer 23 and a second touch layer 22 which are stacked, wherein the first touch layer 21 is arranged close to the display substrate 11 , and the touch insulating layer 23 is arranged between the first touch layer 21 and the second touch layer 22 .

[0040] The present application provides a display panel and a display device, wherein the display panel includes a flat area and a climbing area, wherein the climbing area is arranged around the flat area, and the display panel includes: a display substrate; a touch layer, wherein the touch layer is arranged on the light-emitting side of the display substrate, wherein the touch layer includes a plurality of first touch lines and a plurality of second touch lines arranged crosswise, wherein the orthographic projections of the plurality of first touch lines on the display substrate are located within the flat area; and a cathode, wherein the cathode is arranged between the touch layer and the display substrate, wherein within the flat area, each first touch line is at the same distance from the cathode along a first direction, wherein the first direction is the arrangement direction of the touch layer and the display substrate. The present application arranges the first touch line of the display panel in the flat area, so that the first touch line forms a parasitic capacitance with the cathode only in the flat area, thereby ensuring that the distance between the first touch line and the cathode is the same, thereby ensuring that the parasitic capacitance does not change, thereby greatly improving the stability of the parasitic capacitance between the cathode and the first touch line, and facilitating the display panel to monitor the parasitic capacitance.
