白色光阻材料在O GS工艺中的应用
Application of white matrix material on one glass solution process for touch panel
摘要
Abstract
The chromaticity,resolution and adhesion strength of the white matrix materials for touch panel were analyzed at different conditions of temperatures,thickness and chemical solutions.Thus the white matrix materials were verified for one glass solution (OGS)process for touch panel.First, we focused our studies on the optical density (OD)value,resolution,chemical resistance and ther-mos-stability of the material with different thicknesses.The changes of chromaticity values at differ-ent thicknesses were studied.Then,we applied the white matrix material to the OGS touch panel process.In order to ensure the OD value being greater than 4�0 and make metal line on touch panel in-visible,we proposed a dual layer structure including white matrix layer and black matrix (BM)layer. The white matrix layer thickness was 1 5μm and the BM layer thickness was 1 .2μm.In the practical photo process,we adj usted the process parameters,such as increasing the photo-resistance thickness, exposure intensity and developing time,and successfully solved the metal open and metal remain prob-lems.In the end,the touch panel with white matrix and BM by OGS technology was demonstrated.关键词
