Abstract

The invention discloses a liquid crystal laser display panel and a construction method thereof. The panel comprises an RGB pixel array which is periodically arranged, wherein the RGB pixel array comprises a polymer micro-template and a liquid crystal micro-structure; the polymer micro-template is used as a blank pixel, and the liquid crystal micro-structure is located in the polymer micro-template; the liquid crystal micro-structure comprises a liquid crystal material and organic laser dye molecules. The liquid crystal micro-laser pixel array has the characteristic of periodic arrangement, sothat mixed-color laser output is easy to realize, and full-color laser display is easy to realize in a specific excitation mode.

Description

technical field [0001] The invention belongs to the field of laser display, and in particular relates to a liquid crystal laser display panel and a construction method thereof. Background technique [0002] Laser display, using the characteristics of high monochromaticity and high brightness emitted by laser, has become a revolutionary display industry in the display industry because of its wide color gamut coverage, high color saturation and high color contrast. meaningful technology. The application of laser display technology in portable display devices is hampered by the lack of suitable full-color display panels. Therefore, it is of great significance to develop a pixelated structure capable of full-color laser emission. An effective strategy is to use red-green-blue (RGB) three-color micro-lasers as primitive pixels to construct periodic laser arrays as display panels. So far, RGB laser arrays have been proven by various schemes, such as printed array preparation sc...
