GLOBAL LIGHTING TECHNOLOGIES MICROLENS™ BACKLIGHTING TECHNOLOGY
OFFERS MORE BRIGHTNESS WITH FEWER LEDs

Cleveland OH, January 2001 – MicroLens™ molded backlighting technology from Global Lighting Technologies, Inc.(GLT), provides uniform, high-output backlighting with very low power. Display designers employing standard LCD modules as well as chip-on-glass or "tab"-driven LCDs can achieve higher brightness using fewer LEDs than with other conventional backlighting technologies such as lightpipes or EL.

MicroLens is an LEDÇbased technology that offers similar initial brightness to EL, with 50,000 to 100,000 hours or more time to half brightness.

MicroLens is a recent refinement of GLTºs patented SolidState™ technology. MicroLens light extraction features are precisely molded into the panel, which maximizes the lighting efficiency and is extremely effective for applications where brightness, power and cost are primary design considerations. Panel sizes as large as 1.0" W x 5" L can be backlit – with exceptional uniformity – with only one LED. Since the backlights are LED based, there is no power converter necessary. For a recent backlight designed for Sharp (1.5" by 3.0" with 3 High Brightness Green LEDs), the input power was 0.324 watts with a nominal output of 60 FL at the backlight. A second backlight developed for Seiko (the Vitrium G-4) has a viewing area of 2.5" X 3.25", 4 high brightness white LEDs, input power of 0.432 watts and a nominal output of 53 FL at the backlightºs surface.

Single MicroLens™ panels can light LCD and keypad combinations with as few as two LEDs, drastically reducing the power required to backlight cellular phones, remote control units or other handheld instruments.

MicroLens backlights offer a unique "transition" area that spreads the light uniformly across the active area in an exceptionally thin package. Mechanical holding features can be designed into the backlight to mount chip on glass or chip on flex LCDs or other components, reducing assembly and material costs.

Pricing for GLTºs MicroLens™ backlights ranges from $2.20 or more each for high brightness white, green or blue LEDs in quantities of 100,000 or more; or $0.65 each or more for backlights using standard LED technology in quantities of 250,000 or more, depending on the application.
