Self-luminous projection display system and micro-display full-color optical machine

Abstract

The invention provides a self-luminous projection display system and a micro-display full-color optical machine. The self-luminous projection display system comprises a plurality of light-emitting units used for emitting light of different colors and an optical light-combining unit arranged on a light path of a light beam emitted by each light-emitting unit, wherein the light emitted by the plurality of light-emitting units is combined and emitted to the outside in the same direction. The self-luminous projection display system of the invention has the beneficial effects that the light-emitting units are adopted to directly emit light with different colors, and the light beams emitted by the light-emitting units are combined by the optical light-combining units and emitted along the same direction, thus the design of the traditional back head reflection type projection light path is changed, a self-luminous projection mode is realized, the light path structure is simplified, and the volume is reduced.

Description

technical field [0001] The invention relates to the technical field of projection display, in particular to a self-luminous projection display system and a micro-display full-color light machine. Background technique [0002] Traditional projection systems generally adopt LCOS and DLP design schemes. LCOS (liquid crystal onsilicon, liquid crystal on silicon) is a liquid crystal display formed based on the reflective mode. It is a new reflective display technology that organically combines LCD and CMOS integrated circuits. The imaging of LCOS projection technology adopts reflective optical path. The reflected image is optically separated from the incident light, and then enlarged and imaged on the screen by the projection objective lens. Projectors using LCOS technology do not pass light through the LCD panel, but use this reflection to form an image. Therefore, LCOS is a new reflective microLCD projection technology. The traditional three-chip LCOS imaging system first d...

AI Technical Summary

Problems solved by technology

[0004] Whether it is LCOS or DLP, an initial backlight source is required to form images through the reflected light path, which undoubtedly increases power consumption and device volume, which is not conducive to the miniaturization of projection display devices

Moreover, the lateral size of the optical imaging system of the traditional multi-color projection system is relatively large, and the lateral size of the optical imaging system cannot be further reduced due to the optical path, resulting in a large projection system, which is not conducive to the miniaturization and portability of devices
