Wide viewing angle multi-domain in-plane switching LCD

The bending angle effect on a multi-domain in-plane switching liquid crystal display (MD IPS LCD) using the chevron-shaped electrodes is investigated through a three-dimensional simulation. We find that when the bending angle of the electrodes increases from 10 degrees to 40 degrees, the threshold voltage is lowered from 1.25 V-rms to 0.75 V-rms . With the optimized uniaxial compensation films, the viewing angle of the film-compensated MD IPS LCD is widened to +/- 80 degrees viewing cone while keeping a 100:1 contrast ratio. These outstanding performances are expected to make impact to the flat panel display industry
