| 20110075067 | LASER ILLUMINATED BACKLIGHT FOR FLAT PANEL DISPLAYS - Laser lit flat panel displays are disclosed including edge-lit and direct lit backlights. In certain embodiments, laser assemblies are selected to obtain bandwidth distributions to reduce speckle. | 03-31-2011 |
| 20100182536 | LASER ILLUMINATED BACKLIGHT FOR LIQUID CRYSTAL DISPLAYS - A flat panel display includes a backlight with a plurality of lasing elements. A light distributor distributes light from the lasing elements across the flat panel display. In edge-lit backlights, the light distributor may be a light guide. In direct-lit backlights, the light distributor may be one or more light diffusers that randomize the polarization of light. A polarization enhancement film increases the polarization of light from the light distributor by allowing light of a first polarization to pass through the film and reflecting light that is not of the first polarization back into the backlight. The light reflected back into the backlight is randomly re-polarized within the backlight. An array of light modulators arranged across the flat panel display modulates light emitted by the backlight. | 07-22-2010 |
| 20100149222 | BLUE LASER PUMPED GREEN LIGHT SOURCE FOR DISPLAYS - The invention relates to light sources and displays incorporating blue laser pumped light sources that provide green light. According to a first aspect of the invention, a green light source includes a semiconductor diode laser emitting light in an optical path having a dominant wavelength within the blue spectral region, a substrate positioned in the optical path of the semiconductor diode laser, and a material coupled to the substrate. The material is selected to absorb light emitted by the semiconductor diode laser and, in response, to emit light having a dominant wavelength within the green spectral region. According to a second aspect of the invention, an apparatus includes a lighting module for a display, the lighting module includes an array of red laser light sources, an array of blue laser light sources, and an array of green light sources according to the first aspect of the invention. | 06-17-2010 |
| 20090109658 | LASER ILLUMINATED BACKLIGHT FOR FLAT PANEL DISPLAYS - Laser lit flat panel displays are disclosed including edge-lit and direct lit backlights. In certain embodiments, laser assemblies are selected to obtain bandwidth distributions to reduce speckle. | 04-30-2009 |
