Abstract

Abstract: The direct mechanical touching usually generates mura on a LCD panel. The touch mura cannot always be flashed in a very short period. Touch mura exists in almost every mode of LCD. In this paper, a new type of mura which generated during the LCD module assembly process is investigated. The research results show that LC orientation change from original alignment direction is the main driving‐force of light leakage. A solution to prevent this type of mura is proposed for industrial manufacturing process.
