Light Efficiency in LC Projectors Nearly Doubled

Facebook X LinkedIn Email
RALEIGH, N.C., July 18, 2012 — A new polarization technology that nearly doubles the energy efficiency of liquid crystal (LC) projectors could result in smaller, lower-cost devices with longer battery lives and significantly lower heat levels. All LC projectors use polarized light. Efficient light sources such as LEDs, however, produce unpolarized light. As a result, the light generated by LEDs must be converted into polarized light before it can be used. Conventional methods for polarizing light involve passing the unpolarized light through a polarizing filter, but this process wastes more than 50 percent of...Read full article

    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
