During the early years of video projectors, the experience has focused on television or CRT Cathode Ray Tube technology. Cathode ray tubes are used to generate a television picture. Three small CRT with a single meaning for each primary color and a magnifying glass to light, it helps in the planning of a representation of the color against a large screen in a dimly lit room.
