Field-sequential liquid crystal display employing quantum dot material and projector

Abstract

The invention discloses a field-sequential liquid crystal display employing a quantum dot material and a projector, relates to the technical field of liquid crystal displays and projectors and aims at solving the problems that a traditional silicon-based liquid crystal display is relatively complicated in structure and high in cost. The field-sequential liquid crystal display comprises an excitation light source, a quantum dot color wheel, a liquid crystal display screen, a control system, a mechanical rotation device and a display data buffer; a light facing surface of the quantum dot color wheel is divided into three sectors for alternately transmitting blue light, red light and green light to the liquid crystal display screen separately; and a red light quantum dot layer excited by the excitation light source to emit the red light and a green light quantum dot layer excited by the excitation light source to emit the blue light are arranged on the red light sector and the green light sector separately. By using a light color conversion principle of a quantum dot film and a fast response characteristic of blue-phase liquid crystal, a novel field-sequential liquid crystal display is provided, so that the light energy utilization rate is improved; compared with a traditional LCoS display, the light source device is simplified and the cost of the display is reduced.

Description

technical field [0001] The invention relates to the technical fields of liquid crystal displays and projectors. Background technique [0002] Due to the limited response speed, the current mainstream liquid crystal display generally adopts the principle of spatial color mixing, which has a low utilization rate of light energy, and each display pixel requires three sub-pixels to be synthesized and displayed, resulting in low spatial resolution of the display. Although liquid crystal on silicon (LCoS) adopts the principle of field sequential scanning color mixing, it often requires independent light sources of red, green and blue and passes through an optical mixer. This optical mixer requires relatively high processing technology, so the traditional silicon-based The structure of liquid crystal display is more complicated, and the cost is higher. [0003] DLP is currently the most commonly used projection display technology, but its mechanical stability is insufficient, and ...
