However, a similar concept was used for print heads without an LCD. The first experiments with a direct-driven, transmissive matrix-addressed LCD using a converted slide projector by Peter J. Wild working at Brown Boveri Research in Switzerland were conducted in 1971. A projector was shown in operation at the SID Conference 1972 in San ...
A Zenith 1200 CRT Projector based home theater. Visible extending from the ceiling are three lenses, one each for red, green and blue Black and white CRT projector. A CRT projector is a video projector that uses a small, high-brightness cathode-ray tube (CRT) as the image generating element. The image is then focused and enlarged onto a screen ...
A projector or image projector is an optical device that projects an image (or moving images) onto a surface, commonly a projection screen. Most projectors create an image by shining a light through a small transparent lens , but some newer types of projectors can project the image directly, by using lasers .

This led to Japan launching an LCD industry, which developed large-size LCDs, including TFT computer monitors and LCD televisions. [55] Epson developed the 3LCD projection technology in the 1980s, and licensed it for use in projectors in 1988. [56] Epson's VPJ-700, released in January 1989, was the world's first compact, full-color LCD ...
Industrial laser projectors have been on the market since the early 2000s. Laser projectors are mainly used as optical guidance systems. They enable working without templates in many manufacturing processes by showing directly on the workpiece how material needs to be positioned or mounted, so that the employee is led by manual or semiautomatic productional processes visually.
A projector in a standard form factor: The PG-D2870 projector from Sharp, which uses Digital Light Processing technology An image from a video projector in a home cinema. 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.
Handheld projectors involve miniaturized hardware, and software that can project digital images onto a nearby viewing surface. The system comprises five main parts: the battery, the electronics, the laser or LED light sources, the combiner optic, and in some cases, scanning micromirror devices. First, the electronics system turns the image into ...
