P‐143: Transflective Liquid Crystal Display Using UV Curable Reactive Mesogen

AbstractA single gap transflective liquid crystal display driven by fringe electric field in the transmissive (T) region and vertical electric field in the reflective (R) region was designed with formation of high pretilt angle larger than 45°through polymerization of an UV curable reactive mesogen monomer at the surface in the R region, the effective cell retardation value becomes half of that in the T region where the LCs are homogenously aligned. Consequently, a transflective display driven by a vertical and fringe electric field with a single cell gap and single gamma curves is realized.

Electro-Optic Characteristics of Single Gap Transflective Display Using In-Plane Switching Mode

ABSTRACT We have designed a single gap transflective liquid crystal display (LCD) using an in-plane switching mode, where the rotating angle of the LC director between electrodes, and above electrodes, is 45° and 22.5° in average, respectively. Optimization of the cell structures such as electrode structure, cell structure, physical properties of the LC and the LC cell retardation value have been perform to obtain a low-power transflective LCD with a single gap structure and a single driving circuit.

P-110: A Single Gap Transflective Display using a Fringe-Field Driven Homogeneously Aligned Nematic Liquid Crystal Display

We have designed a single gap transflective liquid crystal display (LCD) driven by a fringe electric field, in which the LCs are homogeneously aligned in the initial state. In the reflective and transmissive areas, the degrees of the rotation of the LC director are 22.5° and 45°, respectively. Utilizing this mechanism and an in-cell retarder with a quarter-wave plate that is used below the LC layer, the transflective LCD using fringe-field switching (FFS) mode is realized.
