We report three major approaches for improving the contrast ratio and viewing angle of a vertical field switching (VFS) blue-phase liquid crystal display (BPLCD). The first approach involves compensation films, the second one uses wire-grid polarizer, and the third one employs an E-type analyzer. Our simulation results show that a contrast ratio over 1000:1 can be achieved. For wide-view applications, we could use a diffuser or curved turning film to steer the high contrast images to different viewing angles.
