Projection system and method for laser to stimulate continuous white light

Abstract

The invention provides a projection system and method for laser to stimulate continuous white light. The projection system comprises a laser generation device, a stimulated luminescence color wheel device, a light combination device, a lighting path optical device, an LCD micro-display device and a projection lens, wherein the stimulated luminescence color wheel device is arranged in front of the emitting end of the laser generation device; the light combination device is arranged in front of the light outlet end of the stimulated luminescence color wheel device; the lighting path optical device is arranged in front of the light outlet end of the light combination device; the LCD micro-display device is arranged in front of the light outlet end of the lighting path optical device and is perpendicular to a light outlet path of the lighting path optical device; the projection lens is arranged in front of the image output end of the LCD micro-display device. The 3LCD projection system is simple in process, low in cost, stable in quality, high in brightness, good in color reducibility and free of flicker, and uses laser to simulate continuous white light.

Description

technical field [0001] The present invention relates to optical projection technology, in particular to a method of using laser to excite three beams of continuous monochromatic light and combining them into continuous white light, which is uniformly lighted, polarized, and split through the lighting optical path system, and then micro-displayed by three LCDs. A projection system and a projection method for performing image processing on a chip. Background technique [0002] Laser display technology is the trend of display technology in the future, and in laser display technology, the advantages of high safety, non-coherence, and high reliability of laser-excited photoluminescent material technology, combined with the color reproduction of 3LCD micro-display technology The advantages of good quality, high color brightness, and no flicker and smear phenomenon will become the mainstream technology in the future home projection display technology. [0003] To achieve laser dis...

Problems solved by technology

There are many problems in this method of laser excitation of segmented excited luminescent materials to generate time-series light and finally superimposed imaging: first, it is easy to produce color shift, and it is impossible to change the intensity of the laser light source to adjust the single primary color; second, it is difficult Improve the brightness of projected imaging images; Third, problems such as low color brightness, poor color reproduction, and image flicker

This utility model patent can solve the problem of certain color saturation, but the method of exciting the three primary color lights by three different laser sources is prone to color shift, and at the same time, due to the discontinuity of light, the generated image will shake the problem arises
