Publication number: 20080094555Abstract: Two phase retardation compensation films with upper and lower slow axes being orthogonal to each other are used to clip a liquid crystal (LC) cell in a transflective liquid crystal display. In an orthogonal polarizer system, the axial difference between the slow axes of the retardation films and the LC molecules director in the LC cell is used to obtain the most suitable phase difference. The ON and OFF of the LC voltage are used to achieve the display function at the darkest state and the brightest state, so as to achieve a transmissive optical mode having low dispersion, wide viewing angle, and ultra-low dark state, without damaging the reflective mode.Type: ApplicationFiled: October 19, 2007Publication date: April 24, 2008Applicant: Wintek CorporationInventors: Yi-Chun Wu, Wen-Jui Liao, Chun-Chi Chi
