Fabrication of Grooved Pattern for the Light Guide Plate of TFT-LCD with CO2 Laser
CO2 레이저 빔을 이용한 TFT-LCD 도광판의 패턴 제작에 관한 연구
Abstract
A light guide panel is an element of the LCD backlight module that is often used for the display of compact electronic devices. In this study, a laser marking system is proposed to fabricate light guide panel, which can be replaced of other manufacturing methods such as silk printing, stamping, and v-cutting methods. The objectives of this research are the establishment of laser marking system, evaluation of laser marking parameters, understanding marking process, application to PMMA, reliability test and quality inspection.
