Light Management Yields Brighter, Crisper Pictures

Simply put, the secret of LCOS is “light management.”

Your LCOS high definition television uses state-of-the-art technology to form a revolutionary, optical system known as a Light Engine. This Light Engine manages and manipulates light like never before, to provide premier HDTV viewing.

The Light Engine begins with an intense, white light source. This intense light is transformed by a series of integration optics and lenses into a rectangular, laser-like beam. The beam then enters a sophisticated prism, where the light is divided into three fundamental colors (red, green, and blue). Each color is then directed towards its own specific, reflective light valve (also called an imager), which contains the modulated HDTV signal. The light reflects off the imager, with the signal attached, and recombines before exiting the prism — forming a perfectly aligned, miniature HDTV picture. This miniature HDTV picture is magnified 70 times through a projection lens system, providing the full size HDTV picture to the screen.
