A video projector is an image projector that receives a video signal and projects the corresponding image onto a projection screen using a lens system. Video projectors use a very bright ultra-high-performance lamp (a special mercury arc lamp ), Xenon arc lamp , metal halide lamp , LED or solid state blue, RB, RGB or fiber-optic lasers to ...
