A Fringe Field Switching Liquid Crystal Display With Fast Grayscale Response Time

A fast-response A-film-enhanced fringe field switching liquid crystal display

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. B...

Fast fringe-field switching of a liquid crystal cell by two-dimensional confinement with virtual walls

We report a simple method for reducing the response time of a fringe-field switching liquid crystal cell by using two-dimensional confinement of the liquid crystals. Through both numerical calculations and experiments, we show that the switching speed can be increased by several fold in a fringe-field switching cell by simply using a rubbing angle of zero, which causes virtual walls to be built...

Fast-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...

A Fast-Response A-Film-Enhanced Fringe Field Switching LCD

We proposed a new A-film-enhanced fringe field switching (AFFS) LCD whose required dn 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.
