Edge lighting utilizing patented MicroLens™ light-extraction technology from Global Lighting Technologies (GLT), Brecksville, OH, provides efficient, LED-based edge lighting technology available for flat-panel displays. The light guides reduce cost, thickness and power consumption, according to the company. They can be used with such LED light sources as RGB and white-phosphor LEDs. The proprietary “transition area” and “lens arrays” help to spread the light uniformly, which reduced the number of LEDs required.

The light guides are being developed in sizes less than 0.5mm thick. GLT provides fully integrated edge-lighting modules with LEDs, films, flexible circuit or PCB and a connector, and the MicroLens light guide. A mechanical holding feature can be designed into the backlight or onto a custom-designed backlight frame.

Applications include LCD and keypad backlights for mobile phones, MP3 players, digital cameras and PDAs; handheld, notebook and desktop computers, and LCD TVs.
