Abstract

A reflective polarizer-free display using dye-doped polymer-stabilized blue-phase liquid crystal (DDPSBP-LC) has been demonstrated. The mechanism is a combination of electrically tunable light absorption and Bragg reflection. In this paper, the influence of light absorption in DDPSBP-LC by changing the dye concentration and absorption paths has been studied. Increased dye concentration can improve the contrast ratio of DDPSBP-LC; however, the response time is the tradeoff. Increasing the cell gap can improve the contrast ratio of DDPSBP-LC; however, the response time remains the same. The study of DDPSBP-LC can help in shutter-glass applications of 3-D displays and electronic paper.
