Abstract

The invention discloses a frame sealing glue composition. The frame sealing glue composition comprises a frame sealing glue, a fluorescent material and a dispersant, wherein the frame sealing glue comprises a prepolymer, an active monomer, a thermal curing agent and a photoinitiator. Through addition of the fluorescent material with a fluorescent effect into the conventional frame sealing glue, the obtained frame sealing glue composition exerts a same adhesive effect as that of the conventional frame sealing glue and facilitates detection of bonding effects on frame sealing glue layers through the fluorescent effect. The invention further discloses a display device and a detection method based on the frame sealing glue composition. The frame sealing glue layers are irradiated by invisible light with wavelength of less than 400 nm, and sealing conditions of the frame sealing glue layers are determined according to the fluorescent effect of the frame sealing glue layers. Thus, bonding effects on the frame sealing glue layers can be conveniently and effectively detected without detection in a special environment, breaking of panels in the process of carrying is avoided, and detection results can be effectively and rapidly obtained.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a frame sealing glue composition, a display device and a detection method. Background technique

[0002] In the preparation process of LCD (Liquid Crystal Display, liquid crystal display), the adhesion effect of the sealant layer directly affects the post-production of the LCD and the quality of the processed LCD. In the manufacturing process of the LCD, the function of the sealing glue layer is to stick the array substrate and the color filter substrate together to play a sealing role, and to ensure the gap between the TFT (Thin Film Transistor, thin film field effect transistor) array substrate and the color filter substrate. Liquid crystals are not affected by the outside air. If there is a defect in the coating process of the sealing adhesive layer, the bonding effect of the sealing adhesive layer will be poor, and the liquid crystal between the array substrate and the colo...
