All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As described in the background art, with the continuous development of display technologies, the applications of display panels are more and more extensive, and the requirements of users on the display effects of the display panels are higher and higher. In the conventional display panel, when the display panel displays, the display panel is close to a part of the frame area side, which has a problem of display yellowing, and the problem seriously affects the display quality of the display panel of a user, and is one of the technical problems to be solved by the technical staff in the field.

Particularly, in the vehicle-mounted touch display device, the design of the support columns in the frame area tends to be consistent with that of the support columns in the display area, for example, the size and density of the support columns in the frame area are consistent with those of the same type of support columns in the display area. However, in the display device, because the signal routing density at the frame area of the array substrate is high, the surface of the array substrate facing the supporting column side is raised to be higher than the portion at the display area; at this time, the supporting columns at the frame region are in contact with the convex surface of the array substrate at the frame region, so that the box thickness of the display device at the frame region is larger than that of the display region, and finally, the display yellowing and other adverse problems occur at the position of the display device close to the frame region.

Therefore, the embodiment of the invention provides a display panel and a display device, which effectively solve the technical problems in the prior art, improve the condition that the display panel is close to the side of the frame area and has the undesirable problems of display yellowing and the like, and improve the display effect of the display panel.

Referring to fig. 1 and fig. 2, fig. 1 is a schematic structural diagram of a display panel according to an embodiment of the present invention, and fig. 2 is a cross-sectional view along the AA' direction in fig. 1. The display panel includes a first substrate 10 and a second substrate 20 disposed opposite to each other, and is divided into a display area AA and a frame area NA located at a periphery of the display area AA.

A plurality of first main supporting columns 101 and a plurality of auxiliary supporting columns 102 are included at the bezel area NA, and a length L1 of the first main supporting columns 101 is greater than a length L3 of the auxiliary supporting columns 102 in a light outgoing direction Y of the display panel; the first main supporting column 101 and the auxiliary supporting column 102 are located on the side of the first base plate 10 facing the second base plate 20, the second base plate 20 includes a base 210, and the second base plate 210 includes a first surface 201 and a second surface 202 facing the side of the first base plate 100, the height H2 from the second surface 202 to the base 210 is greater than the height H1 from the first surface 201 to the base 210, wherein the orthographic projection of the first main supporting column 101 on the base 210 is located within the orthographic projection of the first surface 201 on the base 210.

In an embodiment of the invention, the supporting pillars provided in the invention can be fixedly disposed in the first substrate 10. Wherein the support columns include a first main support column 101, an auxiliary support column 102, and at least one of the types of support columns described below. And the shape of the orthographic projection of the supporting pillar provided by the embodiment of the present invention on the substrate 210 may be a circle, a rectangle, etc., and the present invention is not limited in particular.

It can be understood that, according to the technical solution provided by the embodiment of the present invention, the orthographic projection of the first main supporting column 101 on the base 210 is located in the orthographic projection of the first surface 201 on the base 210, so that the surfaces of the first main supporting column 101 and the second base plate 20 facing the first base plate 10 side are oppositely disposed at the recessed area, and the first main supporting column 101 with a larger length is disposed avoiding the protruding second surface 202, so that the situation that the first main supporting column 101 with a larger length struts the space between the first base plate 10 and the second base plate 20 with a larger box thickness can be improved, the box thickness uniformity of the display panel is ensured to be higher, the situation that the display panel has the undesirable problems of display yellowing and the like near the frame area NA side is improved, and the display effect of the display panel is improved.

In the display panel provided by the embodiment of the present invention, the design of the supporting structure in which the first main supporting column 101 and the auxiliary supporting column 102 are coexisted is adopted, and compared with a display panel in which the auxiliary supporting column is only disposed in the frame region, the display panel provided by the embodiment of the present invention sets the first main supporting column 101 as the main supporting structure and the auxiliary supporting column 102 as the auxiliary supporting structure, so that the situation that the display panel cannot rebound when pressed can be avoided, the supporting effect between the first substrate 10 and the second substrate 20 is improved, and the situation that the support between the first substrate 10 and the second substrate 20 is insufficient can be avoided. Meanwhile, the density of the auxiliary supporting columns 102 does not need to be set to be large, and the situation that water ripples are pressed due to the fact that the friction force in the box at the frame area is too large is avoided.

As shown in fig. 1, the top surface of the first main support pillar 101 facing the second substrate 20 is in contact with the first surface 201. And, the orthographic projection of the auxiliary supporting column 102 provided by the embodiment of the present invention on the substrate 210 may be located within the orthographic projection of the first surface 201 on the substrate 210; or the orthographic projection of the auxiliary support posts 102 on the substrate 210, may also be located within the orthographic projection of the second surface 202 on the substrate 210, which needs to be designed specifically according to the application.

Wherein, when the orthographic projection of the auxiliary supporting column 102 on the substrate 210 is located in the orthographic projection of the second surface 202 on the substrate 210, the top surface of the auxiliary supporting column 102 facing the side of the second substrate 20 may be in contact with the second surface 202, or the top surface of the auxiliary supporting column 102 facing the side of the second substrate 20 may also have a gap with the second surface 202.

As shown in fig. 3, which is a schematic structural diagram of another display panel provided in the embodiment of the present invention, wherein the frame area NA provided in the embodiment of the present invention may be disposed around the display area AA. And, the frame area NA provided by the embodiment of the present invention includes a stepped area NA1, and the first main supporting pillar 101 is located in the stepped area NA 1. The land area NA1 includes a chip bonding area NA11 and a dense wiring area NA12 between the display area AA and the chip bonding area NA11, the chip bonding area NA11 is used for bonding a driving chip for providing a driving signal to the display panel, and the dense wiring area NA12 is used for setting a driving line connected to the driving chip.

As further shown in fig. 3, the first main supporting pillar 101 provided by the embodiment of the present invention is located at the dense routing area NA 12. Because the second substrate 20 includes a large amount of routing lines in the intensive routing area NA12, so make the second substrate 20 towards the condition that unsmooth surface (including first surface and second surface) is more likely to appear in first substrate 10 one side, set up first main support column 101 in this intensive routing area NA12, can solve the great problem of display panel box thickness in this intensive routing area NA12 department, guarantee that display panel's box thickness homogeneity is higher, and then improve the condition that display panel appears the bad problem such as the yellow of demonstration near the regional NA side of frame, improve display panel's display effect.

As shown in fig. 4, which is a schematic structural diagram of another display panel according to an embodiment of the present invention, the second substrate 20 includes a planarization layer 220 located on a side of the base 210 facing the first substrate 10, and a routing layer 230 located on a side of the planarization layer 220 facing the first substrate 10. At the border area NA, the routing layer 230 includes a plurality of electrode leads 2301, wherein an orthogonal projection of the electrode leads 2301 on the substrate 210 is located within an orthogonal projection of the second surface 202 on the substrate 210; and an orthographic projection of the first surface 201 on the substrate 210, wherein a gap between two adjacent electrode leads 2301 is positioned in the orthographic projection on the substrate 210. The electrode lead 2301 provided by the present invention may be a touch signal line, a fingerprint identification signal line, etc., and the present invention is not particularly limited thereto.

The plurality of electrode leads 2301 provided by the embodiment of the invention can be arranged in the dense wiring area of the frame area NA, and the electrode leads 2301 can be connected with the lines of the display area AA and the driving chip, so that the driving chip provides driving signals for the related lines in the display area AA through the electrode leads 2301. Since the electrode wire 2301 is located on the planarization layer 220, the surface of the insulating structure layer formed on the electrode wire 2301 on the side away from the base 210 (i.e., the surface of the second substrate 20 on the side toward the first substrate 10) will be present as an uneven surface including the first surface 201 and the second surface 202. The surface of the insulating structure layer corresponding to the electrode wires 2301 is the second surface 202, and the surface of the insulating structure layer corresponding to the region between the adjacent electrode wires 2301 includes the first surface 201.

It should be noted that the planarization layer 220 provided in the embodiment of the present invention plays a role of protecting and planarizing the surface of the structure layer. The planarization layer 220 has a large thickness and can protect the structural film layer below the planarization layer; meanwhile, the surface of the planarization layer 220 facing the first substrate 10 is flat, so as to planarize the uneven surface of the film layer below the planarization layer, thereby facilitating the preparation of the film layer structure above the planarization layer 220, such as a pixel electrode, a common electrode, a touch signal line, and the like.

As shown in fig. 5 and 6, the routing layer 230 further includes at least one transparent conductive layer 2302 located on a side of the electrode leads 2301 facing the first substrate 10 and spaced apart from the electrode leads 2301. A first insulating layer 231 is provided between the transparent conductive layer 232 and the electrode wire 2301; when the routing layer 230 includes a plurality of transparent conductive layers 232, an insulating isolation layer structure is also provided between adjacent transparent conductive layers 232, and a second insulating layer 233 is further disposed on a side of the transparent conductive layer 232 farthest from the substrate 210 for covering protection. At the display area, at least one of the transparent conductive layers 232 includes a plurality of touch electrodes 2302. At the bezel area NA, the electrode lead 2301 includes a touch electrode lead for connecting the touch electrode 2302. It should be noted that the thickness of the touch electrode 2302 provided by the embodiment of the invention is smaller than that of the electrode lead 2301, so that the unevenness of the surface of the routing layer 230 facing away from the substrate 210 caused by the touch electrode 2302 can be ignored.

Generally, in view of convenience and reliability of the manufacturing process, and in order to avoid an influence of a parasitic capacitance between adjacent electrode leads, the electrode leads extend linearly, that is, the electrode leads extend linearly corresponding to the first surface. In the embodiment of the invention, in order to realize the arrangement of the support pillars at the frame region, the winding part may be formed on the electrode lead, so that the first surface also has a winding position in the extending direction so as to correspond to the first main support pillar. Since the shape of the electrode lead is the same as the shape of the corresponding first surface, the following drawings each illustrate the shape of the electrode lead as an example. As shown in fig. 7, for a schematic structural view of a plurality of electrode leads according to an embodiment of the present invention, the plurality of electrode leads 2301 include a first electrode lead 2311 and a second electrode lead 2312 that are adjacently disposed, and the first electrode lead 2311 includes a first straight portion 2311a and at least one first winding portion 2311 b. A maximum distance between the first straight portion 2311a and the second electrode lead 2312 is D1, and a minimum distance between the first winding portion 2311b and the second electrode lead 2312 is D2, wherein D2 is greater than D1; a first disposition region 23a is formed between the first winding portion 2311b and the second electrode lead 2312, and an orthogonal projection of the first main supporting pillar 101 on the substrate 210 is located within an orthogonal projection of the first disposition region 23 on the substrate 210. Further, by providing the first electrode lead 2311 in a structure including the first winding portion 2311b, a sufficient space is left between the adjacent electrode leads so that the first main supporting pole 101 is correspondingly disposed between the adjacent electrode leads 2301 having a small gap.

Referring to fig. 7, the second electrode lead 2312 according to the present invention extends linearly in a length direction thereof. In the first electrode lead 2311 according to the embodiment of the present invention, since the first winding portion 2311b is provided, the length of the first electrode lead 2311 is relatively increased, and for this reason, the width of the first electrode lead 2311 is set to be greater than the width of the second electrode lead 2312, so as to reduce the overall impedance of the first electrode lead 2311, such that the impedance of the first electrode lead 2311 is substantially different from the impedance of the second electrode lead 2312, and the uniformity of the transmission signals of the electrode lead 2301 is improved. .
