A fast-response A-film-enhanced fringe field switching liquid crystal display
نویسندگان
چکیده
We propose a new A-film-enhanced fringe field switching (A-FFS) liquid crystal display whose required dΔn value is only λ/4, which is one-half of a conventional FFS. Fast response time can be achieved by either decreasing the cell gap (d) or choosing a low birefringence (Δn) and low-viscosity liquid crystal. The effect of dΔn mismatch between A-film and FFS cell on contrast ratio is analysed. By choosing a dispersion-matched A-film, we can obtain a reasonably high contrast ratio in the entire visible region.

A Fast-Response A-Film-Enhanced Fringe Field Switching LCD
We proposed a new A-film-enhanced fringe field switching (AFFS) LCD whose required dn value is only 50% of the conventional FFS. Fast response time can be achieved by decreasing the cell gap, while keeping transmittance over 90%. The parameters which may degrade the contrast ratio are addressed.

Yan Li (SID Student Member) Zhibing Ge (SID Member) Ruibo Lu (SID Member) Meizi Jiao (SID Student Member) Shin-Tson Wu (SID Fellow) Abstract — A fast-response and wide-view liquid-crystal display (LCD) using the crossed fringe-fieldswitching (CFFS) mode is proposed, where the fringe-field electrodes exist on both the top and bottom substrates. The bottom fringe field is used to turn on the LC d...
متن کاملFast-Response Fringe Field Switching LCD with Patterned Common Electrode
A fast-response and wide-view fringe-field switching LCD using patterned common electrodes is proposed. By applying a restoring pulse voltage on common electrodes, LC decay process is expedited. The GTG decay time can be reduced by >7X, depending on the applied erasing voltage. This new mode also preserves the wide-view characteristics as the conventional FFS mode. It is attractive for reducing...
متن کاملUltra-low viscosity liquid crystal materials
We report five ultra-low viscosity nematic liquid crystal mixtures with birefringence around 0.1, dielectric anisotropy in the range of 3 to 6, and clearing temperature about 80°C. A big advantage of these low viscosity mixtures is low activation energy, which significantly suppresses the rising rate of viscosity at low temperatures. Using our mixture M3 as an example, the response time of a 3-...
