A new liquid crystal projector for a work station with high resolution, high level brightness and multisynchronous functions has been developed. It produces a high quality image showing 1280 X 1024 color pixels through a-Si TFT liquid crystal light valves and a high luminous flux at 400 lm through the use of a novel polarization converter. The projection mechanism can be employed not only in front and rear projector, with a screen projection size of up to 200', but also in a novel console type projector with a 70' screen. These projectors can be used for multi media displays, for example, as an electrical overhead projector or a tele-conference system, connected to a work station or a personal computer in the office.
