The projector uses a bright beam of light and a lens system to project the image to a much larger size. A front-projection television uses a projector that is separate from the screen and the projector is placed in front of the screen. The setup of a rear-projection television is in some ways similar to that of a traditional television.

A 140 cm (56 in) DLP rear-projection TV Large-screen television technology (colloquially big-screen TV) developed rapidly in the late 1990s and 2000s.Prior to the development of thin-screen technologies, rear-projection television was standard for larger displays, and jumbotron, a non-projection video display technology, was used at stadiums and concerts.
The Triniscope also saw limited development for consumer television use. One example is the Mitsubishi 6CT-338, which used three 5-inch CRTs arranged behind a faux screen on the front of the display. The image was viewable as a small image centered within the larger faux screen.
Laser color television (laser TV), or laser color video display, is a type of television that utilizes two or more individually modulated optical (laser) rays of different colors to produce a combined spot that is scanned and projected across the image plane by a polygon-mirror system or less effectively by optoelectronic means to produce a color-television display.
After the expiration of Sony's Trinitron patent, manufacturers like Mitsubishi (whose monitor production is now part of NEC Display Solutions) were free to use the Trinitron design for their own product line without license from Sony although they could not use the Trinitron name. For example, Mitsubishi's are called Diamondtron. To some degree ...
DLP technology is used in DLP front projectors (standalone projection units for classrooms and business primarily), DLP rear projection television sets, and digital signs. It was also used in about 85% of digital cinema projection as of around 2011, and in additive manufacturing as a light source in some printers to cure resins into solid 3D ...
In 2007, Texas Instruments introduced stereo 3D capable DLP solutions to its OEMs, [23] Samsung and Mitsubishi then introduced the first 3D ready DLP televisions, and DLP 3D projectors came later. These solutions utilize the inherent speed advantage of the Digital Micro-mirror Device (DMD) to sequentially generate a high refresh rate for the ...
