Abstract

The sheet assembly method of the embodiment of the present invention is used to overcome the technical problem that the internal stress of the adhesive material causes the screen body to warp and deform. It includes: determining the processing direction of the sheet; arranging the liquid adhesive pattern at intervals along the processing direction on the first sheet; pasting the liquid adhesive pattern on the second sheet; The first sheet and the second sheet. Using the principle of fluid mechanics, the flowing liquid adhesive can only fill the gap between adjacent liquid adhesive patterns, so that the deformation internal stress of adjacent liquid adhesive patterns after being rolled cannot be continuously transmitted, which not only satisfies the requirements of the adjacent liquid adhesive The edge of the pattern blends smoothly to form an overall liquid adhesive layer for curing and bonding the first sheet and the second sheet, and ensures that the deformation internal stress of each liquid adhesive pattern will not roll along the processing direction and eventually accumulate at the edge of the sheet The local force on the sheet exceeds the modulus of elasticity of the sheet to cause the sheet to warp.

Description

technical field [0001] The invention relates to display screen packaging, in particular to a sheet assembly method, assembly structure and display screen. Background technique [0002] The sheets are bonded with liquid glue. During the curing process of the liquid glue, the internal stress will change due to the influence of the bonding process. The internal stress after curing has a great influence on the flatness of the sheet. For example, in the current AMOLED (Active-matrix organic light emitting diode) product polarizer attachment process, the polarizer needs to be attached to the screen by rolling (or called rolling) the surface of the polarizer, and the roller is in the process of rolling In this way, the adhesive material between the polarizer and the screen body flows to the edge, and the adhesive material is subjected to uneven force during the flow and curing process, and the interaction between the adhesive material molecules forms a directional internal stress. ...
