LCOSProjektoren

LCOS stands for Liquid Crystal on Silicon. A LCOS projector is a type of digital projector that uses Liquid Crystal Displays (LCDs) manufactured on silicon chips to create images. Unlike traditional LCD projectors that use transparent LCD panels, LCOS projectors use reflective LCD panels.

In a LCOS projector, light from a lamp is passed through a color wheel or is split into red, green, and blue light. Each color is then directed to a separate LCOS chip. The liquid crystals on the surface of each chip act as tiny shutters, controlling how much light is reflected towards the projection lens. By modulating the voltage applied to the liquid crystals, pixels can be individually made transparent or opaque, or partially transparent. The reflected light from all the chips is then combined and projected onto a screen.

LCOS technology is known for producing high-quality images with excellent contrast ratios and deep black levels. This is largely due to the reflective nature of the LCDs, which allows for a more efficient use of light and prevents light leakage. LCOS projectors are often used in applications where image fidelity is critical, such as home theater systems and professional displays. They tend to be more complex and expensive than some other projector technologies.
