    摘要： Direct-lit backlights and associated methods and components are disclosed in which a transflector that partially transmits and partially reflects incident light is shaped to form at least one concave structure facing a back reflector of the backlight. This provides at least one recycling cavity therebetween, the at least one recycling cavity substantially filling the output area of the backlight. At least one light source is disposed behind the output area to inject light into each cavity, and can be positioned in the recycling cavity or behind an aperture in the back reflector. The cavities are preferably shallow and wide, having a width-to-depth ratio of at least 5 or 10, and can provide uniform brightness and color at the output area with sparsely distributed light sources and in a thin profile backlight.

    摘要： 3D stereoscopic viewing enabled by the use of a fast switching speed LCD panel, dynamic backlight, and low cost glasses. The system utilizes an LCD panel with an LED backlight and wavelength selective glasses to isolate each channel by color. The system is based on alternating left and right image frames on an LCD panel. The left and right frames are illuminated by two slightly different red-green-blue light sources that are synchronized sequentially. The light sources are designed to emit light of different spectral composition. The viewer wears glasses where the left lens or filter passes only the spectrum of light used for the left channel of data, and the right lens or filter passes only the spectrum of light used for the right channel of data.
