Study on the Image Quality of Liquid Crystal Display

Abstract

In this thesis, an analytical LCD mode, the Polymer-Dispersed Dual-Scan Liquid Crystal Display (PDDS-LCD) mode, is proposed. In the proposed PDDS-LCD mode, the Polymer-Dispersed technology [2] is employed to achieve a higher and more effective brightness. The employment of Polymer-Dispersed technology helps achieve a dramatically improved brightness but with limitation on improvement of image contrast. In order to address and resolve this problem, the Dual-Scan architecture [17] is employed. For a comparative study with respect to the brightness and contrast of the TN-LCD and IPS-LCD modes, a quantitative analysis of Polymer-Dispersed technology has been conducted to demonstrate the effectiveness of brightness and contrast. The quantitative analysis along with a software simulation has shown and validated the technological benefits in term of structural simplicity as well as image quality.
