I. Introduction to Certified Projector Products銆�

A projector, also known as a video projector, is a device that can project images or videos onto a screen. It can be connected to computers, VCDS, DVDS, BDS, game consoles, DVS, etc. through different interfaces to play corresponding video signals.

Projectors are widely used in homes, offices, schools and entertainment venues. According to different working methods, they come in various types such as CRT, LCD, DLP and 3LCD.
