This article provides information on overhead projectors and their significance in business presentations and management. All projectors take their images from anything capable of generating them, like personal computers, DVD players, videos and digital cameras. Sharp points out when describing its XG-C60X, that a single personal computer, running the supplied SAPS Pro software, can be connected to control a single projector or while groups of the things. This provides the user with advanced control features and the ability to monitor each projector's current status. The two main technologies used to create an image inside the projector, which it then uses its light source to send to the screen, are liquid crystal display and digital light processing. There are some that use cathode ray tube technology but they tend to be very large ones used for public screenings. Digital light processing was developed by Texas Instruments and uses a single chip to project the image rather than the one or three liquid crystal display panels typically found on the other types. This conserves space and makes digital light processing projectors more compact. Epson now uses three high-temperature polysilicon panels.
