[0002] OCR lamination glue is a transparent glue with high viscosity and good optical properties, which can ensure the lamination effect of the LCD screen. At the same time, it also has the function of preventing dust and water vapor from entering the display screen, protecting the normal operation of the LCD panel. During the manufacturing process, the OCR lamination glue is first evenly coated on the surface of the LCD glass, and then the backlight module and other components are placed on the LCD glass. Finally, the curing process is carried out to make the various components tightly bonded together. In this way, the generation of bubbles can be effectively prevented, and the display effect and viewing experience can be improved. Anti-bubble OCR lamination glue-injected LCD display modules are widely used in various electronic products, such as smartphones, tablets, TVs, etc. It not only provides high-quality display effects, but also increases the durability and reliability of the equipment.
