At present, the conventional image projector mainly adopts three projection technologies, namely DLP (Digital Light Processing), 3LCD (3Liquid Crystal Display ) and LCoS.
LCD projectors are high-tech products from the development of liquid crystal technology, lighting technology, and integrated circuits. The key technology is the manufacture of liquid crystal panels. The LCD projector utilizes the photoelectric effect of liquid crystal, i.e., the arrangement of liquid crystal molecules changes under the action of an electric field, which affects the light transmittance or reflectance of the liquid crystal cell, and generates images with different gray scales, levels and colors by projecting RGB three-color light rays through the liquid crystal panel. The liquid crystal display panel is very small, the liquid crystal panel of the household projector is below 1 inch, 200 ten thousand pixels are required to be distributed on the small area, the difficulty is quite high, the production yield of the liquid crystal panel of the projector is not high all the time, the price is high all the time, and at present, a 3-piece LCD projector lower than 8000 yuan is difficult to see. Some thousands of mobile phone liquid crystal screens which are manufactured by a mountain village manufacturer in a mode of illuminating LED light on the rear side of a single mobile phone display screen with a backlight module removed are sold in the market, the mobile phone liquid crystal screens are poor in brightness and uneven in display, and the mobile phone liquid crystal screens which are not special for projection are used, are quick in aging and dark in color, can be used as toys only for playing and do not have practical value.
LCOS projectors are a recently emerging projector display technology, and LCOS (liquid Crystal on silicon), i.e. liquid Crystal with silicon, also called liquid Crystal on silicon, is a matrix liquid Crystal display device based on a reflective mode and having a very small size. The matrix is fabricated on a silicon chip using CMOS technology. The image formation by the LCOS projection technology is made by using a reflective light path. However, compared with the DLP, the LCOS has fatal defects that the requirement for temperature is high, the light with high brightness carries a large amount of heat, the liquid crystal is separated from the aluminum coating, the watermark is easy to appear on the picture, and the viewing is affected, so the LCOS is mostly limited to be in the ultra-miniature projection with low illumination, the figure of the LCOS can not be seen in the products with more than 200Lux, and the LCOS liquid crystal has no way to reach the reaction speed as fast as the DLP.
Therefore, the projectors on the market at present have the problems of low contrast, poor picture color and short response time, and the DLP projector can optimize the problems.
