A curved liquid crystal display panel using frame glue of different thicknesses

Abstract

A curved liquid crystal display panel using glue of different thicknesses, comprising: a first substrate, a second substrate arranged opposite to the first substrate, and glue applied to the peripheral position between the first substrate and the second substrate; the glue comprising: a first glue and a second glue; the first glue is arranged in the peripheral position area of ​​the first substrate and the second substrate; when the curved liquid crystal display panel is in a flat state, a layer of the second glue is added above the first glue located in the middle area; the second glue is the same as or different from the first glue. The present invention increases the reaction force received by the middle area when the panel is bent by thickening the glue in the middle area, thereby suppressing the further reduction of the distance between the two substrates in the middle area, thereby improving the uniformity of the box thickness of the entire curved liquid crystal panel.

Description

Technical Field

[0001] The present invention belongs to the technical field of display devices, and specifically refers to a curved liquid crystal display panel using frame glues of different thicknesses. Background Art

[0002] Liquid crystal displays are the mainstream display product at this stage due to their advantages such as high image quality, light weight, and power saving. They have been widely used in various electronic consumer products such as mobile phones, tablets, and televisions.

[0003] Curved liquid crystal display panels are the current development trend of liquid crystal display panels. However, for curved liquid crystal display panels, the force at the center of the curved surface is the greatest when the panel is bent, and the pressure on the area farther away from the center of the curved surface is smaller. Therefore, if the conventional design of a flat liquid crystal display panel is still adopted, the box thickness at the center of the curved surface will be the smallest, while the box thickness at other positions will increase in a trend that the farther away from the center of the curved surface, the greater the box thickness, thereby greatly reducing the uniformity of the box thickness when the curved liquid crystal display panel is bent, thereby affecting the normal display of the curved liquid crystal display device. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide a curved liquid crystal display panel using frame glues with different thicknesses.

[0005] The present invention is achieved in that:

[0006] A curved liquid crystal display panel using sealants of different thicknesses, comprising:

[0007] a first substrate,

[0008] a second substrate, arranged opposite to the first substrate;

[0009] Frame glue, applied to the peripheral position between the first substrate and the second substrate;

[0010] The frame glue comprises: a first frame glue and a second frame glue;

[0011] The first sealant is disposed at the peripheral area of ​​the first substrate and the second substrate;

[0012] When the curved liquid crystal display panel is in a flat state, a layer of the second sealant is added above the first sealant in the middle area;

[0013] The second sealant is the same as or different from the first sealant.

[0014] Furthermore, when the curved liquid crystal display panel is in a planar state, the thickness of the frame glue gradually decreases from the frame glue located in the central area to the frame glue located in the side area.

[0015] Furthermore, the sealant comprises a mixture of resin, photoinitiator, thermal initiator and filler.

[0016] Furthermore, the first substrate is an array substrate, and the second substrate is a color filter substrate.

[0017] A display device comprises the curved liquid crystal display panel using frame glues of different thicknesses as described above.

[0018] The advantages of the present invention are as follows: by thickening the frame glue in the middle area, the reaction force in the middle area is increased when the panel is bent, thereby suppressing further reduction of the distance between the color film substrate and the array substrate in the middle area, thereby improving the uniformity of the box thickness of the entire curved liquid crystal panel.

[0025] like Figures 1 to 3 As shown, a curved liquid crystal display panel using sealants of different thicknesses comprises:

[0026] The first substrate 100,

[0027] The second substrate 200 is disposed opposite to the first substrate 100.

[0028] Frame glue, applied on the peripheral position between the first substrate 100 and the second substrate 200;

[0029] The frame glue comprises: a first frame glue 101 and a second frame glue 102;

[0030] The first sealant 101 is disposed at the peripheral area of ​​the first substrate 100 and the second substrate 200;

[0031] When the curved liquid crystal display panel is in a flat state, a layer of the second sealant 102 is added above the first sealant 101 in the middle area;

[0032] The second sealant 102 and the first sealant 101 may be the same sealant or different sealants.

[0033] The area division method in this embodiment is only an example. In practice, more areas can be set. After the LCD panel is bent, the stress on the panel gradually changes from the middle to the side. When multiple areas are set, the thickness of the sealant decreases from the center area to the side areas on both sides, which can better ensure the uniformity of the box thickness.

[0034] The frame glue is a mixture consisting of resin, photoinitiator, thermal initiator and filler.

[0035] The first substrate 100 is an array substrate, and the second substrate 200 is a color filter substrate.

[0036] The present invention also relates to a display device, comprising the curved liquid crystal display panel using frame glues of different thicknesses as described above.

[0037] The present invention thickens the sealant in the middle area so that when the panel is bent, the reaction force in the middle area is increased, thereby suppressing further reduction of the distance between the color film substrate and the array substrate in the middle area, thereby improving the uniformity of the box thickness of the entire curved liquid crystal panel.

[0038] The above embodiments and drawings do not limit the form and style of the present invention. Any appropriate changes or modifications made by ordinary technicians in the relevant technical field should be deemed to be within the patent scope of the present invention.
