| Summary: | 碩士 === 國立臺灣科技大學 === 自動化及控制研究所 === 99 === This study focuses on reducing the differential of refractive indexes in whole optical system by filling an epoxy into the air gap between TFT-LCD and cover glass to result in higher transmittance. The anti-reflection packaging is based on a LCD display module which is a critical component of common consumer electrics product on the market. The optical performance such as brightness, color and contrast ratio of the display module could be improved when it is used under outdoor's high illumination environment. First of all, a spectral colorimeter is used to measure the un-packaging display module. With the measurement results by using MFS-Micro Spot Auto equipment, the best thickness of packaging glass material could be decided. The anti-reflection glass with proper thickness is fabricated by using an evaporation process, and assembled with LCD display module by filling an optical epoxy. Meanwhile, eight types of anti-reflection configurations are packaged as comparison. The performances of different packaging configurations are measured in a dark room by using different levels of simulated illumination. The optical performance results are compared with the proposed anti-reflection configuration without changing the panel structure, backlight power consumption and overall thickness. When the epoxy packaging display module is used under high illumination environment of 50,000 lux, the measurement results show that the contrast ratio could be increased about 56.83%. And the performance of CIE 1931 and 1976 NTSC color gamut coverage are improved about 21.4% and 24.4%, respectively. Therefore, such a new anti-reflection packaging method for TFT-LCD module is a possible design.
