LOCA glue construction process requirements in the assembly of the touch screen
There are more and more applications of touch screens, such as smart phones, PADs use touch screens, and more and more touch screens for notebook computers and even TV sets. At present, the touch screen market mainly has two types of resistive and capacitive. The touch screen is made up of two pieces of glass, which are glued together by liquid optical UV glue or double-sided tape. Compared with OCA tape, LOCA liquid UV glue has the advantages of stronger bonding force, flexible control of the thickness of the glue layer, better solution to the fit of the large and medium screen, reduction of light refraction, and elimination of visual phenomena such as rainbow lines. Enhance display contrast, reduce battery consumption, and more.
