A projector, also known as a projector, is a device that can project images or videos onto a screen. You can connect with computer, VCD, DVD, BD, game machine and DV through different interfaces to play corresponding video signals. Projectors are widely used in homes, offices, schools and entertainment places. According to different working methods, there are different types such as CRT, LCD and DLP.

The light sources used by projectors include traditional high-intensity gas discharge light sources (such as ultra-high pressure mercury lamps, short-arc xenon lamps and metal halogen lamps) and new light sources represented by LED light sources and laser light sources.
