Description

Technical Field

[0001] The utility model relates to display technology, in particular to a liquid crystal panel and a display module with a high vibration resistance level. Background Art

[0002] As electric vehicles, especially electric bicycles and electric motorcycles, are becoming more and more popular, high-frequency vibration (generally defined as 5G acceleration or above) is also a trend requirement in the high-end market. Some models even require 10G acceleration and 15G acceleration vibration conditions. This places higher and more detailed requirements on the structural design of vehicle instruments, especially the design of vehicle instruments using LCD panels.

[0003] Traditional liquid crystal panels use spherical supports (known as plastic balls or glass powder in the industry) between the upper and lower glass substrates to ensure that the liquid crystal box has a sufficiently uniform thickness. This sandwich structure design has almost no constraints between the substrate glass, the spherical support and the liquid crystal material, which means that when external force is applied, there will be displacement between the three. This structure is no problem in coping with general application conditions. However, when the liquid crystal panel is in a vibration environment with a high acceleration, due to the relative position changes between the above three, at a specific vibration frequency, the vibration of the spherical support relative to the glass substrate and the liquid crystal material (which can be understood as a "microscopic resonance phenomenon") will cause the liquid crystal material to have a phenomenon similar to "water ripples". This leads to uneven display problems. Utility Model Content

[0004] In order to solve the above-mentioned deficiencies in the prior art, the utility model provides a liquid crystal panel with a high vibration resistance level.

[0005] The utility model also provides a display module, comprising the above-mentioned liquid crystal panel.

[0006] The technical problem to be solved by the utility model is achieved through the following technical solutions:

[0007] A liquid crystal panel with a high vibration resistance level comprises an upper substrate, a lower substrate, a liquid crystal material and a plurality of spherical support bodies arranged between the upper substrate and the lower substrate, a transparent film layer is provided on the lower surface of the upper substrate or the upper surface of the lower substrate, the transparent film layer forms a plurality of limit retaining walls, and each spherical support body is distributed between adjacent limit retaining walls.

[0008] Furthermore, the distance between adjacent limiting retaining walls is 3-5 times the diameter of the spherical support body.

[0009] Furthermore, the transparent film layer is arranged on the lower surface of the upper substrate, and the lower end of each limiting retaining wall abuts against the upper surface of the lower substrate.

[0010] Furthermore, the width of each limiting retaining wall gradually decreases from its upper end to its lower end.

[0011] Furthermore, the transparent film layer is arranged on the upper surface of the lower substrate, and the upper end of each limiting retaining wall abuts against the lower surface of the upper substrate.

[0012] Furthermore, the width of each limiting retaining wall gradually decreases from its lower end to its upper end.

[0013] Furthermore, each limiting retaining wall includes a plurality of first limiting retaining walls, each of which extends along the first direction and is arranged in parallel along the second direction.

[0014] Furthermore, each limiting retaining wall includes a plurality of second limiting retaining walls, each of which extends along the second direction and is arranged in parallel along the first direction.

[0015] Furthermore, the transparent film layer is a UV adhesive film layer or an epoxy resin film layer.

[0016] A display module comprises a backlight module and the above-mentioned liquid crystal panel, wherein the liquid crystal panel is arranged on the light-emitting side of the backlight module.

[0017] The utility model has the following beneficial effects: the liquid crystal panel of the utility model is provided with a transparent film layer having the limiting retaining wall on the lower surface of the upper substrate or the upper surface of the lower substrate, and the limiting retaining wall can form a barrier to the spherical support bodies to limit the displacement range of each spherical support body, thereby preventing each spherical support body from being displaced too far relative to the upper substrate, the lower substrate and the liquid crystal material when the panel is subjected to external force; when the liquid crystal panel is in a vibration environment with a relatively high acceleration, at a specific vibration frequency, when the spherical support bodies cause the liquid crystal material to exhibit a phenomenon similar to "water ripples", the limiting retaining wall can also block the transmission of the "water ripples" to limit the spread of the "water ripples", thereby improving the problem of uneven display and improving the vibration resistance level.

[0031] like Figure 1 As shown, a liquid crystal panel with a high vibration resistance level includes an upper substrate 11, a lower substrate 12, and a liquid crystal material 13 and a plurality of spherical supports 14 arranged between the upper substrate 11 and the lower substrate 12. The upper substrate 11 and the lower substrate 12 are relatively fitted and fixed in the outer area by a sealant 15. The upper substrate 11, the lower substrate 12 and the sealant 15 together enclose a sealed space for accommodating the liquid crystal material 13 and the plurality of spherical supports 14; each spherical support body 14 is used to support and maintain the box thickness between the upper substrate 11 and the lower substrate 12, and its upper and lower sides are respectively against the upper substrate 11 and the lower substrate 12; a transparent film layer 16 is provided on the lower surface of the upper substrate 11, and the transparent film layer 16 forms a plurality of limit retaining walls 161, and each spherical support body 14 is distributed between adjacent limit retaining walls 161.

[0032] The liquid crystal panel of the present invention is provided with a transparent film layer 16 having a limiting retaining wall 161 on the lower surface of the upper substrate 11. The limiting retaining wall 161 can block the spherical support bodies 14 to limit the displacement range of each spherical support body 14, thereby preventing each spherical support body 14 from being displaced too far relative to the upper substrate 11, the lower substrate 12 and the liquid crystal material 13 when the panel is subjected to external force; when the liquid crystal panel is in a vibration environment with a relatively high acceleration, at a specific vibration frequency, when the spherical support bodies 14 cause the liquid crystal material 13 to exhibit a phenomenon similar to "water ripples", the limiting retaining wall 161 can also block the transmission of the "water ripples" to limit the spread of the "water ripples", thereby improving the problem of uneven display and improving the vibration resistance level.

[0038] Preferably, the width of each limiting retaining wall 161 gradually decreases from its upper end to its lower end, so that the distance between adjacent limiting retaining walls 161 gradually increases from top to bottom, thereby improving the accommodation capacity of the liquid crystal material 13.

[0039] In a specific implementation, Figure 3 As shown in Figure 4, each limiting retaining wall 161 includes a plurality of first limiting retaining walls 16a, each first limiting retaining wall 16a is a serrated retaining wall, a linear retaining wall, a discontinuous dotted retaining wall, or a dot-line combination retaining wall extending in the first direction, and is arranged in parallel along the second direction; each spherical support body 14 is distributed between adjacent first limiting retaining walls 16a.

[0042] In this embodiment, the first direction is perpendicular to the second direction, the first direction is the lateral direction of the liquid crystal panel, and the second direction is the longitudinal direction of the liquid crystal panel. However, in a specific implementation, the first direction and the second direction can also be set at any angle, and the first direction and the second direction can also be inclined directions of any angle of the liquid crystal panel.
