Transflective fringe-field switching liquid crystal display using an embedded wire grid polarizer

Abstract

A single-cell-gap and single-gamma transflective liquid crystal display (TR-LCD) using fringe-field switching is achieved by an embedded wire grid polarizer. In the proposed TR-LCD, the common electrode is patterned into nano-sized wire grids in the reflective part whereas it remains a plane shape in the transmissive part. The nano-sized wire grids play dual roles as common electrode and reflective polarizer in the reflective part. By optimizing the pixel electrode structures, a single gamma curve for the reflective and transmissive parts is demonstrated. Such a TR-LCD is free from in-cell retarder, compensation film, and additional reflector.
