P‐208: High Strength Technology Apply to One Glass Solution for Touch Panel

Abstract

The paper is proposed that adding OC layer after black matrix process during sensor can improve surface strength of TLCM and surface strength will be better with the increasing thickness of OC layer. The result is suggested that slimming OC0 thickness (<0.8um) significantly sloved optical problem-rainbow issue caused by the wrinkle of OC from ITO sputtering at high temperature (230 ); When OC0 thickness exceed over 0.8um, we can adopt lower temperature ( 180 ) ITO sputtering to eliminate rainbow. The paper is also shown to optimize index matching layer to adjust chromaticity and pattern shadow.

Progress in optical adhesive and lamination process of touch screen in 3C products

“…The core of OGS technology is the integration of cover glass and touch screen 73 . By plating an ITO conductive layer on the inside of the protective glass, coating and photolithography are directly performed to obtain a thinner touch screen 74,75 . On‐cell technology refers to the method of embedding the touch panel between the color filter plate and the polarizing plate of the display screen; as shown in Figure 5A, the touch panel is equipped on the LCD panel 76 .…”
