Description

technical field

[0001] The invention relates to the technical field of adhesives, in particular, the invention relates to an ultraviolet light-curable silicone liquid optical adhesive composition, a preparation method and an application thereof. Background technique

[0002] In order to improve the display effect of the display screen under strong light or direct sunlight, and achieve light and thin, anti-vibration, anti-slip and waterproof effects, touch screen manufacturers and processing companies have developed a full lamination process. Full lamination means that the panel and the touch screen are seamlessly pasted together with liquid optical glue or optical tape, which can reduce the reflection and refraction of light on the display screen, improve the transmittance, increase the contrast, and improve the display effect indoors and outdoors . OCA optical adhesive is used to bond the upper and lower surfaces in the form of double-sided tape, which is prone to air bubb...
