Problems solved by technology

[0004] There are mainly two types of PS in the prior art. One is softer material, which has large elastic deformation. Although the range of high and low temperature LC margin is wide, PS has large deformation under dynamic pressure

Embodiment 1

[0035] refer to figure 1 and figure 2 , The spacer assembly of this embodiment includes an upper spacer 10 and a lower spacer 20, which are fixed on the inner surfaces of the upper substrate 1 and the lower substrate 2, respectively. Wherein, the upper spacer 10 includes a combination (not shown) formed by the first spacer part 11 and the second spacer part 12 with a height difference, and the lower spacer 20 is formed on the lower spacer 20 to cooperate with the upper spacer 10. Pressing surface (not shown). It can be understood that, in other embodiments, the upper spacer 10 and the lower spacer 20 can also be fixed on the lower substrate 2 and the upper substrate 1 respectively.

[0036] Such as figure 1 , in this combination, the end portion of the first spacer part 11 protrudes from the end face of the second spacer part 12, thereby forming the side surface of the first spacer part 11 and the second spacer part at the free end of the combination. The transitional ste...

Embodiment 2

[0049] Such as Figure 4 and Figure 5 As shown, different from Embodiment 1, the upper spacer 10 of the spacer assembly of this embodiment further includes a main spacer post 3 of a cylindrical structure fixed on the inner surface of the upper substrate 1 .

[0050] Preferably, the height of the main spacer column 3 is the same as the height of the first spacer part 11 in the composite structure, and the main spacer column 3 corresponds to the concave part on the pressing surface.

[0051] Specifically, after the installation is completed, the ends of the main spacer column 3 and the first spacer part 11 in the combined structure are all pressed on the pressing surface, and the first spacer part 11 in the combined structure plays a role in contact with the main spacer. The spacer 3 has the same function, and both act as the main spacer together, while the second spacer part 12 is suspended. The sum of the contact density or distribution density of the first spacer part 11 i...

Embodiment 3

[0055] Such as Figure 6 and Figure 7 As shown, the difference from Embodiment 1 is that the distance between the end surface of the second spacer part 12 and the pressing surface of the separate column structure of the spacer assembly in this embodiment is greater than that of the second spacer in the assembly The distance between the portion 12 and the pressing surface makes the upper spacer 10 of this embodiment have three kinds of contact distances with the pressing surface, which has better compression resistance and wider range of high and low temperature LCMargin.

[0056] Preferably, the same as in Embodiment 1, the end faces of the second spacer part 12 of the single column structure and the second spacer part 12 in the combined structure of this embodiment are also flush, so that the upper spacer 10 as a whole also has only two heights, and can be manufactured using a half-grayscale mask process, which can simplify the manufacturing process and reduce manufacturing...

Abstract

The invention discloses a liquid crystal display panel and a spacer assembly thereof. The spacer assembly comprises an upper spacer and a lower spacer which are used for being fixed to an upper substrate and a lower substrate, the upper substrate and the lower substrate are oppositely arranged, the upper space comprises at least one first spacer part and at least one second spacer part, and the distance between the end face of the first spacer part and a pressing face is smaller than that between the end face of the second spacer part and the pressing face. Due to the fact that the segment difference is formed in the upper spacer, when the liquid crystal display panel is located under the low-temperature condition or bears dynamic pressure, the portion, with the minimum contact density or distribution density, of the upper spacer is firstly used for supporting, when the portion, closest to the pressing face, of the upper space bears pressure and certain deformation is generated, the portion, slightly farther away from the pressing face, of the upper spacer is used for supporting and bears part of pressure, the anti-pressure capacity of the liquid crystal display panel is improved, and high and low temperature LC margin ranges of the liquid crystal display panel can be both taken into consideration.

Description

technical field [0001] The invention relates to the field of liquid crystal display technology, in particular to a liquid crystal display panel and a spacer assembly thereof. Background technique [0002] With the advancement of display technology, liquid crystal display panels are used more and more widely. However, liquid crystal display panels are usually formed by pouring liquid crystals between glass substrates. The structure of liquid crystal display panels determines that its products will be Changes in external temperature lead to expansion or contraction of materials such as glass substrates and liquid crystals. In addition, these products are often impacted by external forces such as touch, which can easily cause dislocation of the upper and lower substrates of the liquid crystal display panel, resulting in light leakage from the panel, which will affect the display effect. The color is not correct, the effect is not good, and many other adverse effects. [0003] ...
