The inventor finds that the reason that the dark state uniformity capability of the existing display panel is poor is mainly that the display panel is easy to generate light leakage in a dark state, so that the brightness of a light leakage part is obviously brighter than that of other parts. Among the causes of the dark state light leakage problem of the display panel, the uneven stress of each part of the display panel due to the existence of the extrusion stress phase difference in the display panel is a main cause. The source of the extrusion stress phase difference in the display panel is mainly that the friction force between the substrate and the support column of the liquid crystal display panel is larger, so that the substrate extrusion stress phase difference of the display panel is formed. The poor uniformity of the dark state of the display panel severely affects the user experience. Based on the research on the above problems, the inventor provides a display panel and a display device to improve the dark state uniformity of the display panel, thereby improving the display quality of the display panel.

Fig. 5 is a reference diagram of a usage state of a display panel according to an embodiment of the application, as shown in fig. 5. The backlight module 14 is arranged on one side of the display panel 1, which is away from the light emitting surface, the backlight module 14 is usually in a bowl-shaped design, and after the edge of the bowl-shaped backlight module 14 is contacted with the peripheral area A2, the peripheral area A2 is easy to squeeze, so that the support columns 12 in the peripheral area A2 cannot rebound as early as possible, and the peripheral area A2 has a squeezing stress phase difference. By setting the first area density to be larger than the second area density, that is, by reducing the second area density, friction between the support columns 12 and the peripheral area A2 can be reduced, thereby improving stress uniformity of each partial area in the display panel 1 and improving dark state light leakage.
In one possible embodiment, as shown in fig. 4, the central area A1 and the peripheral area A2 have the same shape and size of the support columns 12, the ratio of the number of support columns 12 in the central area A1 to the total area of the central area A1 is a first number density, and the ratio of the number of support columns 12 in the peripheral area A2 to the total area of the peripheral area A2 is a second number density, which is smaller than the first number density.
In the above embodiment, the shape and size of the support columns 12 in the central area A1 and the peripheral area A2 are the same, i.e., only one specification of support columns 12 is included in the display panel 1. In the above embodiment, the friction force of the support columns 12 in the peripheral area A2 against the first substrate 10 is reduced by reducing the number density of the support columns 12 in the peripheral area A2, thereby reducing the stress phase difference of the peripheral area A2.
In one possible embodiment, the ratio of the second number density to the first number density is A, 0.25.ltoreq.A.ltoreq.0.5.
The ratio of the first number density to the second number density is set to 0.25-0.5, so that the friction force of the peripheral area A2 on the support columns 12 is reduced while the supporting effect of the central area A1 and the peripheral area A2 is ensured, the stress phase difference of the peripheral area A2 which is easy to be extruded and deformed is reduced, and the surface uniformity of the display panel 1 is improved.
In one possible embodiment, as shown in fig. 6, the peripheral area A2 includes a plurality of peripheral partitions A0, the plurality of peripheral partitions A0 are nested in sequence along a direction away from the central area A1, a ratio of the number of support columns 12 in each peripheral partition A0 to a total area of the peripheral partitions A0 is a third number density, and the third number density of the plurality of peripheral partitions A0 decreases in sequence along the direction away from the central area A1.
In the above embodiment, the display panel 1 may have a regular shape, such as a rectangle, a circle, etc., and the peripheral area A2 includes a plurality of peripheral partitions, which are nested one inside another in a direction away from the central area A1, and the peripheral partition A0 farthest from the central area A1 is most interfered by external compressive stress, so that the light leakage phenomenon is most likely to occur. The greater the interference from the external compressive stress, the greater the friction of the support column 12 against the peripheral partition, and thus the greater the compressive stress phase difference of the peripheral partition A0. According to the rule that each peripheral partition A0 is generally affected by interference, the third number density of each peripheral partition A0 is set to be gradually decreased along the direction away from the central area A1, so that the extrusion stress phase differences of each peripheral partition A0 are similar, and the reduction of the friction force of the peripheral area is realized on the premise of ensuring the internal support strength of the display panel, so that the dark state uniformity of the display panel 1 is improved.
In one possible implementation, as shown in fig. 6, fig. 6 is a schematic structural diagram of a second substrate in another display panel provided by an embodiment of the present application, where the plurality of peripheral partitions A0 includes a first partition A3 and a second partition A4, the second partition A4 is located on a side of the first partition A3 away from the central area A1, a ratio of a third number density of the first partition A3 to a first number density of the central area A1 is B, 0.5+.b+.1, and a ratio of a third number density of the second partition A4 to the first number density of the central area A1 is C, 0.25+.ltoreq.c+.0.5.
In the above embodiment, the third number density of each peripheral partition A0 may gradually decrease in the direction away from the central area A1, when the plurality of peripheral partitions A0 includes the first partition A3 close to the central area A1 and the second partition A4 away from the central area A1, the decreasing amplitude of the first partition A3 may be 50% -0, and the decreasing amplitude of the second partition A4 may be 25% -50%, so as to avoid the cliff-like decrease, so as to ensure the smooth transition of the supporting forces in the central area A1 and each peripheral partition A0, and simultaneously, on the premise of ensuring the supporting effect, the number of the support columns 12 of each peripheral partition A0 is properly reduced according to the positions of each peripheral partition A0, so that the friction force between the peripheral partition A0 and the support columns 12 is reduced, thereby improving the influence of the friction force of the peripheral partition A0 by the support columns 12 and improving the uniformity of the stress phase difference of the display panel 1.
In another possible implementation, as shown in fig. 7, fig. 7 is a schematic structural diagram of a second substrate in another display panel provided by an embodiment of the present application, the friction force of the support columns 12 on the peripheral area A2 can be reduced by reducing the end surface area of the support columns 12, wherein the end surface area of the support columns 12 in the peripheral area A2 is smaller than the end surface area of the support columns 12 in the central area A1.
In the above embodiment, it is ensured that the first number density of the central area A1 is the same as the second number density of the peripheral area A2, that is, the total friction force of the support columns 12 to the peripheral area A2 is reduced by reducing the end surface area of the support columns 12 in the peripheral area A2 without changing the second number density of the peripheral area A2. In this embodiment, the support points of the support columns 12 in the peripheral area A2 are ensured to be unchanged, the station distribution of the support columns 12 is maintained, and the support effect is ensured.
Or the second number density of peripheral areas A2 may be simultaneously reduced to further reduce the friction of support columns 12 against peripheral areas A2.
In one possible embodiment, the peripheral area A2 includes a plurality of peripheral partitions A0, the plurality of peripheral partitions A0 are nested one inside another in a direction away from the central area A1, and the end surface areas of the support columns 12 in the plurality of peripheral partitions A0 decrease one after another in the direction away from the central area A1.
In the above embodiment, the display panel 1 may have a regular shape, such as a rectangle, a circle, etc., and the peripheral area A2 includes a plurality of peripheral areas A0, and the plurality of peripheral areas A0 are nested in sequence along the direction away from the central area A1, so that the peripheral area A0 farthest from the central area A1 is subjected to the interference of external compressive stress to the greatest extent, and the light leakage phenomenon is most likely to occur. The greater the interference from the external compressive stress, the greater the friction of the support column 12 against the peripheral partition, and thus the greater the compressive stress phase difference of the peripheral partition A0. According to the rule that each peripheral partition A0 is generally affected by interference, the end surface area of each peripheral partition A0 is set to be gradually decreased along the direction away from the central area A1, so that the extrusion stress phase differences of each peripheral partition A0 are similar, and the dark state uniformity of the display panel 1 is improved.
In a possible implementation manner, as shown in fig. 8, fig. 8 is a schematic structural diagram of a second substrate in another display panel provided by the embodiment of the present application, where the plurality of peripheral areas A0 includes a first area A3 and a second area A4, the second area A4 is located at a side of the first area A3 away from the central area A1, the end surface of the support column 12 in the central area A1 is a first end surface 121, the end surface of the support column 12 in the first area A3 is a second end surface 122, the end surface of the support column 12 in the second area A4 is a third end surface 123, and the second end surface 122 and the third end surface 123 are inscribed on the first end surface 121.
In the above embodiment, the areas of the first end surface 121, the second end surface 122 and the third end surface 123 are gradually reduced, and the second end surface 122 and the third end surface 123 are inscribed in the first end surface 121, so that the shape distribution of the second end surface 122 and the third end surface 123 can be ensured, each end surface is ensured to be limited in the range of the first end surface 121, the occurrence of excessively extreme shapes is avoided, and the more stable support is ensured as much as possible on the premise of reducing the area of the end surfaces.
In one possible embodiment, the first end surface 121 is circular or elliptical in shape, the second end surface 122 is polygonal in shape, and the third end surface 123 is triangular or diamond in shape.

The regular patterns such as circles, squares and triangles are adopted, so that the center of the support of each support column 12 is coincident with the center of the end face pattern, and the stability of the support is improved.
Specifically, the shapes of the first end surface 121, the second end surface 122, and the third end surface 123 may be other shapes, and the present application is not particularly limited.
In one possible embodiment, as shown in fig. 7, when the display panel 1 is rectangular, the display panel 1 includes a long side L1, the length of the long side L1 is L1, the central area A1 is rectangular, the peripheral area A2 is a rectangular ring surrounding the central area A1, and the minimum distance between the edge of the peripheral area A2 and the edge of the central area A1 is L2,0.05×l1+.l2+.0.2×l1.
In the above embodiment, the minimum distance between the edge of the peripheral area A2 and the edge of the central area A1 is set to be within the interval of 0.05×l1 to 0.2×l1, so that the support columns 12 with larger area density can be arranged in a sufficient space in the central area A1 to ensure the supporting effect of the central area A1 of the display panel 1, and meanwhile, the distribution range of the peripheral area A2 is considered, so that the distribution range of the peripheral area A2 which is easy to generate the extrusion stress phase difference is not too large to cause insufficient supporting of the display panel 1, and is not too small to cause easy to generate the extrusion stress phase difference in the display panel 1, thereby effectively reducing the probability of poor display and light leakage of the display panel 1, that is, the above embodiment realizes the problems of poor display and light leakage of the display panel 1 and is helpful for improving the overall performance of the display panel 1.
In the above embodiment, when the display panel 1 is rectangular, the peripheral area A2 may be a rectangular ring structure, and the peripheral area A2 is in a regular shape, so that the manufacturing process is simpler and the manufacturing process is easy to divide.
In the above embodiment, the peripheral area A2 may be irregularly shaped, and only the minimum distance between the edge of the peripheral area A2 and the edge of the central area A1 needs to be L2, where L1 is 0.05×l1.ltoreq.l2.ltoreq.0.2×l1, i.e. L2 may fluctuate.
In a possible implementation manner, as shown in fig. 9, fig. 9 is a schematic structural diagram of a second substrate in another display panel provided by the embodiment of the present application, when the peripheral area A2 includes a first partition A3 and a second partition A4, and the second partition A4 is located on a side of the first partition A3 away from the central area A1, the first partition A3 is a rectangular ring surrounding the central area A1, the second partition A4 is a rectangular ring surrounding the first partition A3, a minimum distance between an edge of the first partition A3 facing the second partition A4 and an edge of the central area A1 is L3,0.1×l1×l3×l3×l1, and 0.2×l1, and a minimum distance between an edge of the second partition A4 away from the first partition A3 and an edge of the first partition A3 away from the central area A1 is L4, and 0.05×l1×l4×l4×l1.
In the above embodiment, the peripheral area A2 includes the first partition A3 and the second partition A4, and the first partition A3 and the second partition A4 are rectangular rings, so that the partition is easy in the preparation process, and the preparation process is simpler.
In the above embodiment, the peripheral area A2 is divided into the first partition A3 and the second partition A4, the first partition A3 is located between the second partition A4 and the central area A1, and is a transition area, the area density of the support columns 12 in the first partition A3 is greater than the area density of the support columns 12 in the second partition A4 and is smaller than the area density in the central area A1, so that the transition of the area density is realized. By further dividing the peripheral area A2, the area density of the support columns 12 in the peripheral area A2 is gradually reduced, and abrupt changes caused by the cliff-type reduction at the junction of the central area A1 and the peripheral area A2 are avoided. In the display panel 1, the position close to the edge region is more likely to be interfered by the compressive stress than the position far from the edge region, and the interfered region and the support column 12 are likely to generate friction to cause a compressive stress phase difference, thereby affecting the dark state uniformity of the display panel. Because the second partition A4 is closer to the edge of the display panel than the first partition A3, the influence of the friction force of the support columns 12 on the second partition A4 in the display panel 1 is the greatest, so that the area density of the support columns 12 is reduced greatly by centralizing the area, the light leakage problem of the second partition A4 can be improved deeply, and meanwhile, the area density of the support columns 12 of the first partition A3 is reduced less than that of the central area A1, so that both the supporting effect and the overaction can be realized.
In a possible implementation manner, as shown in fig. 10, fig. 10 is a schematic structural diagram of another display panel provided by an embodiment of the present application, when the display panel 1 is a special-shaped display panel 1 having an irregular polygon shape, the peripheral area A2 further includes a plurality of peripheral sub-areas A5, the peripheral sub-areas A5 are arranged along a direction surrounding the central area A1, the peripheral sub-areas A5 include at least two sides 13 coinciding with edges of the peripheral area A2, a first included angle a is formed between the two sides 13, and the first included angle a is an acute angle or an obtuse angle.
When the first included angle a in the peripheral sub-area A5 is an acute angle, the ratio of the end surface area of the support column 12 in the peripheral sub-area A5 to the total area of the peripheral sub-area A5 is the third area density, and the ratio of the third area density to the first area density is D. When the first included angle a in the peripheral sub-area A5 is an obtuse angle, the ratio of the end surface area of the support column 12 in the peripheral sub-area A5 to the total area of the peripheral sub-area A5 is the fourth area density, and the ratio of the fourth area density to the first area density is E. Wherein 0< D < E <1.
In the above embodiment, the display panel 1 is a special-shaped display panel 1, and the peripheral sub-area A5 with the first included angle a being an acute angle and the peripheral sub-area A5 with the first included angle a being an obtuse angle exist in the edge of the special-shaped display panel 1, so that the peripheral sub-area A5 with the acute angle is more likely to interfere, and the acute angle position is also relatively fragile and is easily jacked up and damaged, so that the third area density can be smaller than that of the obtuse angle area. Since the obtuse angle area is located in the peripheral area A2 and is also susceptible to the extrusion of the bowl-shaped backlight, the fourth area density of the support columns 12 in the obtuse angle area is set smaller than the first area density of the central area A1, and since the area is adversely affected smaller than the peripheral sub-area A5 having an acute angle, the fourth area density can be set larger than the third area density, thereby achieving a compromise of the supporting effect.
In a possible implementation manner, as shown in fig. 11, fig. 11 is a schematic structural diagram of another display panel provided by an embodiment of the present application, and the display panel 1 may also be a special-shaped display panel 1 shown in fig. 11, which is formed by enclosing a linear side and an arc-shaped side intersecting the linear side.
In one possible implementation, as shown in fig. 12, fig. 12 is a schematic structural diagram of a second substrate in a display panel according to another embodiment of the present application, where the end surface area of the support columns 12 in the peripheral sub-area A5 is smaller than the end surface area of the support columns 12 in the central area A1, and/or the shape and size of the support columns 12 in the central area A1 and the peripheral sub-area A5 are the same, the ratio of the number of support columns 12 in the peripheral sub-area A5 to the total area of the peripheral sub-area A5 is a fourth number density, the ratio of the number of support columns 12 in the central area A1 to the total area of the central area A1 is a first number density, and the fourth number density is smaller than the first number density.
In the above embodiment, the area density of the support columns 12 in the peripheral sub-area A5 can be reduced by reducing the number of the support columns 12 in the peripheral sub-area A5 to reduce the area density of the support columns 12 in the peripheral sub-area A5 and/or reducing the end surface area of the support columns 12 in the peripheral sub-area A5 on the premise of ensuring that the support columns 12 in the display panel 1 are of the same specification, and the present application is not limited in particular. The above embodiments can reduce the area density of the support columns 12 in the peripheral sub-area A5, thereby reducing the friction between the support columns 12 and the peripheral sub-area A5, improving the surface uniformity, and reducing the occurrence probability of poor peripheral display of the display panel 1.
The present application also provides a display device 2, as shown in fig. 13, fig. 13 is a schematic structural diagram of a display device provided by the embodiment of the present application, where the display device 2 includes any one of the display panels 1 provided in the foregoing embodiments of the present application.
The display device 2 may be a visual rearview mirror of an automobile, a liquid crystal dashboard, a center control display screen, or the like, and the present application is not particularly limited. The occurrence probability of the problems of light leakage and poor display at the edge of the display device 2 is greatly reduced, and the user experience is effectively improved.
