Liquid crystal diffraction grating
TL;DR: In this paper, the potential difference applied between the electrodes is applied by suitable means to determine the direction of propagation of the light beam in order to obtain a more complete view of the liquid crystal interface.
Patent
Electric field gradient excited liquid crystal cell having bistability
TL;DR: In this paper, Voltages are selectively applied to each of the second and third electrodes such that the stable state of the liquid crystalline layer is changed from the ordered (homeotropic) or clear state, to the disordered (focal conic) or dark state.
Patent
Twist nematic type liquid crystal display device
TL;DR: In this paper, the orientation treatment of liquid crystal molecules by dividing it into the clockwise and counterclockwise minute regions of their twist directions was proposed to eliminate the defects that display quality degrades depending upon viewing directions and decrease the dependency of display quality on the angle of view of the display quality.
