摘要

We demonstrate a reflective polarizer-free display using dye-doped polymer-stabilized blue phase liquid crystals (DDPSBP-LC). The mechanism is mainly the combination of electrically tunable light absorption and Bragg reflection. At the voltage-off state, the dye molecules and liquid crystals form the structure of the double twist cylinders. As a result, the DDPSBP-LC is in dark state due to the combination of Bragg reflection and light absorption. At the voltage-on state, the blue phase structure is unwound locally. The DDPSBP-LC is then in bright state because of the small light absorption only. The response time of DDPSBP-LC is fast, the viewing angle is wide, and the optical efficiency is high. The applications of such a switch are shutter glass of 3D displays, and electronic papers.
