Method for improving plastic frame curing rate in LCD (liquid crystal display) panel cell process, and LCD panel

Abstract

The invention provides a method for improving the plastic frame curing rate in an LCD (liquid crystal display) panel cell process, and an LCD panel. The method comprises the following steps: a) an array substrate and a color filter substrate after assembly are provided, a plastic frame layer is arranged in a non-display area between the array substrate and the color filter substrate, and a light blocking layer is arranged in the non-display area on one side surface, facing to the plastic frame layer, of the array substrate; b) light for curing the plastic frame layer enters the plastic frame layer from the color filter substrate side, so as to cure the plastic frame layer. The method has the advantages that the light for curing the plastic frame layer enters the plastic frame layer from the color filter substrate side, so that the blocking of an peripheral metal circuit of the array substrate to the light for curing the plastic frame layer is avoided, and the problem about reliability is avoided; the light blocking layer is arranged on the array substrate, so that light rays of a backlight source is prevented from going out from the position of the plastic frame layer, and light for curing the plastic frame layer can be prevented from being blocked by the light blocking layer.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for improving the curing rate of a plastic frame in a box forming process of a liquid crystal panel and a liquid crystal panel. Background technique [0002] At present, the large-scale use of flat-panel TVs and mobile display terminals has made the manufacture of LCD panels develop on a large scale. see figure 1 , in the manufacturing process of the liquid crystal panel, the array substrate 10 and the CF color filter substrate 11 are manufactured separately, and then the array substrate 10 and the CF color filter substrate 11 are combined in opposition through the cell forming process. There is a liquid crystal layer 12 between the array substrate 10 and the CF color filter substrate 11, and the liquid crystal layer 12 is sealed by a sealant 13 coated around the panel. [0003] The frame glue 13 is a jelly-like glue that needs to be cured by irradiation with UV ...

AI Technical Summary

Problems solved by technology

Generally, the frame glue 13 requires that the illuminated area be greater than 30%, so as to meet the requirement of complete curing of the frame glue 13, otherwise the frame glue 13 will not be completely cured, and the seal of the frame glue 13 of the LCD panel is not good, resulting in reliability problems, such as LCD Leaks, bubbles, etc. are bad
