Viewing angle switchable blue‐phase liquid crystal display with low voltage and high transmittance

Abstract

-We propose a viewing angle switchable blue-phase liquid crystal display with low voltage and high transmittance. In this device, in-plane protrusions are used to lower operating voltage and improve the transmittance. Besides, the top electrode can control viewing angle of the proposed display. When no voltage is applied to the top electrode, the display shows wide viewing angle mode. On the contrary, this display shows narrow viewing angle mode. So, this device exhibits low operating voltage, high transmittance, and good viewing angle controllable characteristics.Keywords -blue-phase, viewing angle switchable display, wide viewing angle mode, narrow viewing angle mode.
