Problems solved by technology

However, if the spacer 18 is located on the periphery of the black matrix 124, it will not be able to achieve the supporting function. Although this area is small, when UV light is used for photohardening, this area is directly responsible for the adhesion of the panels, which will affect the adhesion strength between panels and the panel. gap

Abstract

The invention provides a structure and a method for enhancing the adhesive strength of a panel sealant. The structure comprises an upper substrate, a lower substrate and a supporting area, wherein a sealant is coated on the circumference of the lower substrate; the supporting area is positioned in the range of the sealant; the supporting area comprises a plurality of supports with concavo-convex surfaces and a plurality of spacers; the supports are formed on the upper substrate; and the spacers are positioned between the supports and the lower substrate. The supporting strength of the upper and the lower substrates is increased by the supports and the spacers; the supports with a concavo-convex design can increase the adhesive area of the sealant and the upper substrate; and the adhesive strength can be increased after the upper and the lower substrates are combined into the panel.

Description

【Technical field】 [0001] The invention relates to a semiconductor substrate combination technology, in particular to a structure and method for increasing the adhesion strength of panel frame glue. 【Background technique】 [0002] A liquid crystal panel is assembled from an upper substrate and a lower substrate. After coating the lower substrate with sealant and injecting liquid crystals, the upper substrate and the lower substrate can be assembled, and the two substrates are bonded together with the sealant. In addition to the function of adhering the upper and lower substrates, the frame glue also has the function of supporting the distance between the liquid crystal cells, such as figure 1 As shown, the upper substrate 12 includes a color filter substrate 122, a black matrix 124, and a conductive layer 126. After the lower substrate 10 is coated with a sealant 14, the upper substrate 12 and the lower substrate 10 are assembled. Within the scope of the sealant 14 And a spa...
