Projection technology of projector 3LCD technology DLP technology LCD technology LCoS technology (LCoSSXRDD-ILA) What's the difference and which is better?

3LCD technology, also known as liquid crystal technology, is one of the earliest technologies put into use in modern projection technology and still belongs to the mainstream. It originated in Japan and was first invented and used by Epson and Sharp. It entered the China market in about 95. Its core principle is that the light is divided into three primary colors through color filters, and then converged on the prism through three liquid crystal sheets, and output through the lens. Advantages: the light is processed by three primary colors, the color is restored well, the color is gorgeous, and the color gamut is wide. Disadvantages: more light refraction, more internal reflective refractive lenses. Often a lens is aging, which will lead to poor overall effect. The aging speed is similar to DLP, but after aging, the whole picture is not dark, but the color of the whole picture is uneven. Summary: Cheng also defeated Xiao He in Xiao He. Suggestion: Play games, color first, 3LCD is preferred. Because technology originated in Japan, Japanese machines are much better than European and American brands.

DLP technology, also known as DMD chip technology, is one of the two mainstream projection technologies at present. It originated in Texas, USA, and was put into commercial use in 1997. Entered China around 2000. The main technical principle is to realize output by reflecting light from DMD chip. At present, the single-chip DLP machine is common. Because of its low price, low light refraction and small size, it quickly occupies the market. Disadvantages: the internal refraction of light is less, the color is quite different from that of LCD with the same parameter, and the text playback is more suitable. Suggestion: the price is cheap, suitable for people who are nervous at hand. You can get a similar one for more than 2000 yuan. European and American brands are preferred, and domestic products need to be improved.

LCOS technology is a new technology that appeared in 2005-06, and it is an upgrade of 3LCD technology. The core principle is the refraction technology of liquid crystal panel, and LCD is the transmission technology of liquid crystal panel, which has less loss of refracted light, more saturated color and more beautiful color. First introduced by Japanese brands, it is called a new projection technology. However, due to the characteristics of the technology itself, the demand for ultra-high resolution is the highest, but the market generally does not require ultra-high resolution, and the price is relatively high, so the promotion is stagnant. Moreover, the rapid development of 3DLP projection in recent years has severely squeezed the LCOS market. At the beginning, LCOS also launched two or three machines of a few brands, but there were still a few projectors, which never touched the mainstream market. Summary: The original new technology is now chicken ribs. It's time for the hour, but it's not necessarily good. Suggestion: This kind of projection is less, less optional and more expensive. Although the effect is the best of the three technologies, it is definitely much better than LCOS to buy a 3DLP with that money.
