One of the opposing surfaces is co-planar with either the light emission surface or the light reflection surface. A light source is disposed adjacent to the light input surface. The light source emits light into the light input portion. A reflective layer is disposed adjacent to or on the opposing side surfaces. | 11-05-2009 |
20100165660 | BACKLIGHT AND DISPLAY SYSTEM USING SAME - A backlight that includes a front reflector and a back reflector that form a hollow light recycling cavity including an output surface is disclosed. The backlight further includes one or more light sources disposed to emit light into the light recycling cavity. The front reflector includes an on-axis average reflectivity of at least 90% for visible light polarized in a first plane, and an on-axis average reflectivity of at least 25% but less than 90% for visible light polarized in a second plane perpendicular to the first plane. | 07-01-2010 |
20100208041 | STEREOSCOPIC 3D DISPLAY DEVICE - 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. | 08-19-2010 |

20110134347 | STEREOSCOPIC 3D LIQUID CRYSTAL DISPLAY APPARATUS WITH SLATTED LIGHT GUIDE - A scanning backlight for a stereoscopic 3D liquid crystal display apparatus includes a light guide formed from a plurality of segments. Each segment has a first side and a second side opposite the first side, and a first surface extending between the first and second sides and a second surface opposite the first surface. The first surface substantially re-directs light and the second surface substantially transmits light. The plurality of segments are arranged substantially in parallel and with the second surfaces transmitting light in substantially the same direction to provide backlighting for a stereoscopic 3D liquid crystal display. A first light source is disposed along the first side of each segment for transmitting light into the light guide from the first side, and a second light source is disposed along the second side of each segment for transmitting light into the light guide from the second side. Each segment first and second light source is selectively turned on and off in a particular pattern and each segment light source selectively transmits light into the light guide first side or light guide second side to form a scanning backlight. | 06-09-2011 |
