Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of display, more particularly, to a display panel and a display device. BACKGROUND

[0002] With the development of science and technology, more and more electronic devices with display function are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and becomes an indispensable important tool for people today.

[0003] The liquid crystal display panel is a display panel widely used in the market at present, which generally comprises an array substrate, a color film substrate and liquid crystal filled between the array substrate and the color film substrate. In the manufacturing process of the array substrate, alignment liquid coating will be performed, and after baking, an alignment film is formed to provide a pre-tilt angle for liquid crystal molecules, so that the rotation direction of the liquid crystal molecules is consistent.

[0004] However, there are a large number of vias in the array substrate. When the alignment liquid is applied, for the deep vias, the alignment liquid near the hole flows a lot, and the alignment liquid will remain in the hole, while the alignment liquid around the hole is thin, which causes abnormal deflection of liquid crystal near the deep hole, and the display panel shows diagonal lines, affecting the display effect of the display panel. SUMMARY

[0005] Therefore, the present application provides a display panel and a display device to improve the above situation.

[0006] In a first aspect, the present application provides a display panel, comprising an array substrate and a color film substrate arranged oppositely; the array substrate comprises a substrate, a planarization layer, a first electrode layer, a first insulating layer and a second electrode layer;

[0007] The planarization layer is located on the side of the substrate close to the color film substrate, the first electrode layer is located between the planarization layer and the first insulating layer, and the second electrode layer is located on the side of the first insulating layer away from the substrate; the thickness of the first insulating layer along the first direction is less than the thickness of the planarization layer along the first direction, and the first direction is the thickness direction of the display panel.

[0008] The array substrate further comprises a touch control trace and a touch control electrode, the touch control electrode is located on the first electrode layer, the touch control trace comprises at least one first touch control trace, the first touch control trace comprises a first line segment located on the second electrode layer, and the first line segment is electrically connected with the touch control electrode through a first connecting hole located on the first insulating layer.

[0009] In a second aspect, the present application provides a display device comprising the display panel provided in the first aspect.

[0010] Compared with the prior art, the display panel and the display device provided by the application at least achieve the following beneficial effects:

[0011] The application provides a display panel and a display device. The display panel comprises an array substrate and a color film substrate arranged oppositely. The array substrate comprises a substrate, a planarization layer, a first electrode layer, a first insulating layer and a second electrode layer. The planarization layer is located on the side of the substrate close to the color film substrate. The first electrode layer is located between the planarization layer and the first insulating layer. The second electrode layer is located on the side of the first insulating layer away from the substrate. The thickness of the first insulating layer along a first direction is less than the thickness of the planarization layer along the first direction. The first direction is the thickness direction of the display panel. The array substrate further comprises a touch control trace and a touch control electrode. The touch control electrode is located on the first electrode layer. The touch control trace comprises at least one first touch control trace. The first touch control trace comprises a first segment located on the second electrode layer. The first segment is electrically connected to the touch control electrode through a first connecting hole located on the first insulating layer. The display device comprises the display panel. The first touch control trace in the touch control trace comprises the first segment. The first segment is connected to the touch control electrode through the first connecting hole. Since the thickness of the first insulating layer is less than the thickness of the planarization layer, the first connecting hole in the embodiment of the application is located on the first insulating layer with a smaller thickness. Compared with the scheme in which the connecting hole is arranged on the planarization layer with a larger thickness, the first connecting hole in the application has a shallower hole depth. When an alignment liquid is formed on the side of the array substrate facing the color film substrate, since the alignment liquid has a certain flowability, if there are many deep holes on the array substrate (for example, the holes connecting the touch control electrode and the touch control trace are all deep holes), recesses will be formed at the positions corresponding to the deep holes. In this way, the alignment liquid will flow into the recesses, resulting in uneven thickness of the alignment film formed after the alignment liquid is solidified, and the problem of local over-thickness. Therefore, in the embodiment of the application, the first connecting hole (the connecting hole connecting the first segment of the first touch control trace and the touch control electrode) is formed on the first insulating layer with a smaller thickness, which reduces the depth of the connecting hole and is beneficial to reducing the number of deep holes on the array substrate and reducing the phenomenon that the alignment liquid gathers at the connecting hole to form an alignment film with local excessive film thickness, improving the abnormal film thickness of the local alignment film, and further improving the display abnormality of the display panel and improving the display effect of the display panel.

[0012] Of course, any product implementing the present application does not necessarily need to achieve all the technical effects described above.

[0065] Figure 12 FIG. 6 shows a schematic diagram of another embodiment of the display panel provided by the present application, which is described as follows. Figure 4 and Figure 12 Optionally, the display panel includes a binding area 30 and a plurality of touch electrode columns 120 arranged along a third direction, the touch electrodes 121 in the same touch electrode column 120 are arranged along a second direction, and the second direction and the third direction intersect.

[0066] In the same touch electrode column 120:

[0067] The number of the first connecting holes 181 corresponding to the n-th row of touch electrodes 121 is a;

[0068] The number of the first connecting holes 181 corresponding to the n+1th row of touch electrodes 121 is b; wherein the distance between the nth row of touch electrodes 121 and the binding area 30 along the second direction is less than the distance between the n+1th row of touch electrodes 121 and the binding area 30 along the second direction, n is a positive integer, a≤b.

[0069] Specifically, the display panel 100 provided by the present application comprises a binding area 30 and a plurality of touch electrode columns 120, and the number a of the first connecting holes 181 corresponding to the n th row of touch electrodes 121 in the same touch electrode column 120 is less than the number b of the first connecting holes 181 corresponding to the n+1th row of touch electrodes 121, that is, along the second direction, the closer to the binding area 30 the touch electrode 121 is, the more the number of the first connecting holes 181 corresponding to the touch electrode 121 is, that is, the first connecting holes 181 are arranged close to the binding area 30, so that the display panel 100 can improve the display effect while reducing the RC Loading of the first touch wire 601.

[0070] It should be noted that the first connecting hole 181 is located in the first insulating layer 15, the first connecting hole 181 connects the first line segment 6011 in the first touch wire 601 and the touch electrode 121, the thickness of the first insulating layer 15 is small, so the depth of the first connecting hole 181 is shallow, which can improve the local alignment film thickness abnormality and improve the display effect of the display panel 100; at the same time, since the RC Loading of the first line segment 6011 is large, the first connecting hole 181 is arranged close to the binding area 30, which shortens the length of the first line segment 6011 in the first touch wire 601, thereby reducing the RC Loading of the first touch wire 601.

[0071] It should be further noted that in the same touch electrode 121, the position of the first connecting hole 181 on the same touch wire 60 can be selected to be arranged at intervals or continuously, which can be designed according to actual conditions, and the present application does not make specific limitation.

Since the arrangement of the first connection holes 181 increases the impedance and coupling capacitance of the first touch control wire 601, the continuous arrangement of the first connection holes 181 on the side close to the binding area 30 can reduce the RC Loading of the first touch control wire 601.

[0074] It should be noted that the first connection holes 181 are located on the first insulating layer 15, and the depth of the holes is shallow, which can improve the abnormality of the alignment film thickness and improve the display effect of the display panel 100. At the same time, the continuous arrangement of the first connection holes 181 on the side close to the binding area 30 further shortens the length of the first line segment 6011 in the first touch control wire 601, thereby reducing the RC Loading of the first touch control wire 601.

[0075] It should be further noted that the first connection holes 181 and the third connection holes 183 are both holes on the first insulating layer 15.
