FUTURE : [|CRT projector] using [|cathode ray tubes]. This typically involves a blue, a green, and a red tube. Minimal maintenance is required. This is the oldest system and falling out of favor largely. However, it does provide the largest screen size for a given cost. CRT projectors are suitable only for fixed installations. [|LCD projector] using [|LCD] light gates. This is the simplest system, making it one of the most common and affordable for home theaters and business use. Its most common problem is a visible “screen door” or pixelation effect, although recent advances have minimized this. [|DLP projector] using [|Texas Instruments]’ [|DLP] technology. This uses one, two, or three [|microfabricated] light valves called [|digital micromirror devices] (DMDs). The single- and double-DMD versions use rotating color wheels in time with the mirror refreshes to modulate color. The most common problem with the single- or two-DMD varieties is a visible “rainbow” which some people perceive when moving their eyes. [|LCOS projector] using [|Liquid crystal on silicon]. [|D-ILA] JVC’s Direct-drive Image Light Amplifier based on LCOS technology.
