TripleLCD

TripleLCD refers to a display or projection system that uses three separate liquid-crystal display (LCD) panels to modulate red, green, and blue light in parallel, forming full-color images through additive color synthesis. In a typical tripleLCD projector, a light source (lamp or LED) emits white light that is split by dichroic mirrors into RGB components. Each component passes through its respective LCD panel, which controls light transmission to create the image for that color channel. The three modulated beams are then recombined by a prism or beam-splitter and projected onto a screen.

The architecture is designed to produce accurate color reproduction and brightness by handling all primary colors separately, reducing color artefacts that can occur when color filtering is combined after projection. This approach often results in vivid color saturation and a relatively wide color gamut. TripleLCD systems have been widely used in home theater and educational projectors, particularly during the 1990s and early 2000s, before other technologies such as DLP and LCOS gained prominence.

Advantages of tripleLCD include good color accuracy, absence of a color wheel (which can reduce motion artifacts in some DLP systems), and generally robust reliability. Common drawbacks include higher susceptibility to alignment and convergence issues between panels, potential light loss leading to lower native contrast compared with some competing technologies, and higher component costs due to maintaining three LCD assemblies.

TripleLCD is commonly contrasted with single-LCD, DLP, and LCOS projection technologies. See also 3LCD and projection displays.
