Embodiment approach

[0015] Regarding the specific position expression of the above-mentioned sealing bar 1, it can be understood in this way: the sealing bar 1 moves inwardly relative to the sealing 4 inside the display screen housing 100, and the sealing bar 1 does not enter the display area 5 or does not exceed the black matrix area. More specifically, the vertical distance H between the tip 13 of the sealing bar 1 and the outer edge of the display screen housing 100 provided with the sealing 4 is greater than 0.3 mm, and the opening end of the sealing bar 1 is in contact with the The vertical distance between the display area or the black matrix area and the outer edge of the seal is greater than 0.7 mm. According to an embodiment provided by the present invention, the vertical distance H between the tip 13 of the sealing bar 1 and the outer edge of the display screen housing 100 provided with the sealing 4 can be set to 0.3mm, and the sealing bar The vertical distance between the open end of...

Abstract

The invention discloses a liquid crystal display screen comprising a display screen shell, wherein a seal is arranged on the display screen shell, a seal blocking strip corresponding to the seal is arranged in the display screen shell, sealed frame glue is arranged on a frame of the display screen shell, the seal blocking strip is in a reversed V shape, and a reversed V-shaped opening end of the seal blocking strip is back to the inner side of the display screen shell. Because the seal blocking strip is designed in the reversed V shape, and the reversed V-shaped opening end thereof faces to the inner side of the display screen shell, a channel can be used for indicating liquid crystal to flow, the liquid crystal can enter the display screen shell along the edge of the frame glue, thereby the damage of a PI layer of the seal can be reduced in a certain extent when the liquid crystal is filled, and the bad contrast condition of the seal can be improved, and meanwhile, because the designenlarges a liquid crystal filling caliber of the seal, the filling efficiency of the liquid crystal can be increased in a certain extent.

Description

【Technical field】 [0001] The invention relates to the field of liquid crystal display screens, in particular to a sealing structure for liquid crystal display screens. 【Background technique】 [0002] Currently, a liquid crystal display generally has a seal through which liquid crystals are injected into the liquid crystal display. However, in general designs, sealing bars are provided to prevent damage to the PI layer when filling liquid crystals, and to protect the sealing at the same time. [0003] Such as figure 1 as well as figure 2 As shown, it is a structural schematic diagram of an existing liquid crystal display screen and an enlarged schematic diagram of an existing liquid crystal display screen seal. The frame glue 2' for sealing around the display screen housing 100, the display area 5, the sealant 3 for sealing the seal, and the seal bar 1' arranged opposite to the seal 4'. For the design of the sealing bar 1', it is restricted by the two factors of filling ...
