A biaxial film-compensated thin homogeneous cell for reflective liquid crystal display

Abstract

Two-dimensional measurements of cell parameter distributions in reflective liquid crystal displays by using multiple wavelengths Stokes parameters J. Appl. Phys. 95, 4371 (2004); 10.1063/1.1650892 Effects of cell structure on the reflection of cholesteric liquid crystal displaysComputer simulations on the display characteristics of a biaxial film compensated thin homogeneous liquid crystal cell are performed. Results indicate that the biaxial film-compensated reflective displays exhibit a relatively weak wavelength dispersion, wide viewing angle, high contrast ratio, low operation voltage, abundant gray scale, and fast response time. Their potential applications for reflective direct-view and color-sequential projection displays are emphasized.

Liquid-Crystal-on-Silicon for Augmented Reality Displays

“…Due to the narrow viewing angle and the staggered RGB dark state, the HG cell is rarely used for broadband intensity modulation but is a favored choice for a reflective phase modulator. The viewing angle can be enlarged by a compensation film and by the mirror image effect in reflective LCoS [35]. The unmatched RGB phase retardation is not a big issue for phase modulation.…”

Simplex based method for compensation films optimization in TN-LCD

“…Since most LC materials are optically uniaxial with a positive birefringence (n e >n o ), the vertical aligned liquid crystal molecules in the region can be regarded as a positive C-plate film. According to the phase matched method [3][4][5][6][7] , the compensator must be made of optically uniaxial media with a negative C-plate film. In the region and , the twist angle is 90°.…”

P‐184: Optical Compensation for High Contrast Ratio in Reflective Horizontal Switching LC Cell

“…Reflective liquid crystal displays (LCDs) are considered as suitable display devices because of their small weight and low power consumption. It provides high brightness compared with the double polarizer mode [1][2][3][4][5]. On the other hand, there is a problem of the polarizer mode that has low contrast ratio in comparison with the double polarizer mode due to the light leakage in the dark state.…”
