Investigation of the viewing-angle compensation possibilities of π-cells
نویسندگان
چکیده
The aim of this paper is to clarify which kinds of retardation foils are most suited to extend the viewing angle of π-cells [1]. For this reason we focussed on the simulated conoscopic retardation plots of the π-cell on the one hand and of the retardation foils on the other hand. Among the foils we investigated are hybrid retardation layers with positive and negative birefringence, homogeneous biaxial retardation layers and compensation structures consisting of a Fuji Wide-View (FWV) foil and an extra retardation layer. We believe that our approach excludes the existence of other compensation foil candidates than the ones we proposed.

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 to 40 , the threshold voltage is lowered from 1.25 Vrms to 0.75 Vrms. With the optimized uniaxial compensation films, the viewing angle...
