Abstract

This application provides a liquid crystal color display device and method based on single-pixel color. The device includes: an ITO glass layer, a liquid crystal layer, and a substrate layer arranged in layers. Multiple pixel units are disposed on the substrate layer. Each pixel unit includes a pixel electrode and a pixel control unit. The liquid crystal layer is used to change the wavelength of emitted light according to the control voltage output by the pixel control unit, thereby changing the displayed color. The thickness of the liquid crystal layer satisfies the condition that the phase delay of light in the liquid crystal layer transmission path exceeds 2π, i.e., n*2d>λ, to form an effective FP resonant cavity. This application can directly achieve color display under white light illumination or even natural light illumination using a single pixel unit array, under the action of a control voltage, realizing color display under white light incident light.
