Multi-domain homeotropic liquid crystal display based on ridge and fringe field structure

View publication


A ridge and fringe field multi-domain homeotropic (RFFMH) liquid crystal display was demonstrated. The operating principle of this new display mode is the combination effect of a fringe field and ridge structure to control the tilt direction of the liquid crystal molecules when a voltage is applied. No rubbing treatment is required and, with proper compensation films, the display has very wide viewing angles.
