LCD projector is a projection device based on liquid crystal display technology, mainly using three-chip high-temperature polycrystalline silicon liquid crystal panel (HTPS) technology, by controlling the liquid crystal molecular arrangement to adjust the transmittance to achieve color imaging. This technology was first applied to the VJP-2000 model by Epson in 1989. The products are divided into two categories: liquid crystal panel projectors and liquid crystal light valve projectors.

A beam-splitting system is used to decompose the RGB three-color light and modulate it through the liquid crystal plate to synthesize the image, and the light sources include metal halide lamps, UHP/UHE lamps, and a new type of laser/LED light source.

LCD projector is a device that allows light to pass through three liquid crystal chips that can “change the picture”, and then overlap the red, green and blue pictures to form a large color picture. Its main advantage is that colors are usually more vivid and full.
