Embodiment 1
[0048] figure 1 It is a schematic diagram of the relationship between the amount of liquid crystal and the amount of light leakage when the display panel is bent. Such as figure 1 As shown, the amount of light leakage increases with the increase of the amount of liquid crystal, so the amount of light leakage is proportional to the amount of liquid crystal. figure 2 It is a schematic diagram of the relationship between the path difference and the amount of light leakage when the display panel is bent. Such as figure 2 As shown, the amount of light leakage decreases with the increase of the optical path difference, so the amount of light leakage is inversely proportional to the optical path difference. In addition, the amount of liquid crystal is inversely proportional to the friction force generated when the display panel is bent, and the optical path difference is directly proportional to the friction force generated when the display panel is bent. Therefore, the amount ...
Embodiment 2
[0054] Figure 5 It is a schematic structural diagram of a display panel provided by Embodiment 2 of the present invention. Such as Figure 5 As shown, the first support structure 102 is in contact with the second substrate 201, the top of the first support structure 102 is a first arc surface, and the radian and curvature radius of the first arc surface are the same as those of the second The substrates 201 are the same, wherein the dotted ellipse shows the mutual contact surfaces of the first supporting structure 102 and the second substrate 201 . Optionally, the second substrate 201 is an array substrate. Figure 6 for Figure 5 A structural schematic diagram of the first supporting structure shown, Figure 7 for Figure 5 Another structural schematic diagram of the first supporting structure shown. Such as Figure 6 and Figure 7 As shown, the dotted ellipse shows that the top of the first support structure 102 is in the shape of a cambered surface. In this embodi...

[0059] Friction P H =μ·E·S·ΔL / L, where μ is the coefficient of friction, E is the coefficient of elasticity, S is the contact area, ΔL is the height change of the spacer, and L is the height of the spacer. From the friction formula P H =μ·E·S·ΔL / L It can be known that the effective way to increase the friction force of the spacer is to increase the friction coefficient in addition to increasing the contact area. Figure 8 It is a schematic structural diagram of a display panel provided by Embodiment 3 of the present invention. Such as Figure 8 As shown, the second support structure 202 is a second concave-convex structure, and the second concave-convex structure is arranged opposite to the first support structure 102 . In this embodiment, the second support structure 202 is set as a second concave-convex structure, which not only increases the contact area of the spacer, but also increases the friction coefficient of the spacer, thereby increasing the friction between th...
