Modular edge lighting using patented MicroLens light extraction technology from Global Lighting Technologies (GLT) provides LED-based edge lighting technology for flat panel displays. This concept brings molded-in optics, higher brightness (more output/W), thinner construction and a scalable design to illumination of LCDs from < 1 inches to >50 inches diagonal, using high-brightness LEDs (HBLEDs) as the light source. Molded light guides enable edge-lit backlighting, and they can reduce the thickness and power consumption associated with traditional direct backlighting methods that use an LED array under the display. These lights can be used with a range of LED light sources, including RGB and white phosphor LEDs. Applications include LCD and keypad backlights for mobile phones, MP3 players, camcorders, digital cameras, PDAs, GPS devices, handheld games and portable DVD players.
