MicroLens LED Edge-Lighting

BRECKSVILLE, Ohio, March 13, 2007 -- Modular edge-lighting using patented MicroLens light extraction technology from Global Lighting Technologies (GLT) provides the most efficient LED-based edge lighting technology available for today’s flat-panel displays, the company said.

GLT-132.jpgThe MicroLens concept brings molded-in optics, higher brightness (more output/watt), thinner construction and a scalable design to illumination of LCDs from <1 in. to >50 in. diagonal, using high-brightness LEDs (HBLEDs) as the light source. GLT's MicroLens molded light guides enable outstanding edge-lit backlighting performance, and they can reduce the high cost, thickness, and power consumption associated with traditional direct backlighting methods that use an LED array under the display.

MicroLens edge lights, according to GLT, provide exceptional output and uniformity and can be used with a wide range of LED light sources, including RGB and white phosphor LEDs.

MicroLens' proprietary transition area and lens arrays help to spread the light uniformly, reducing the number of LEDs required, while its micro-optical elements precisely extract light for optimal performance.

"Compared to other edge-lighting technologies, MicroLens enables more dramatic improvements in color mixing and visual appearance," said David DeAgazio, GLT's director of sales worldwide. "With up to 180,000 unique optical features per square inch (or 2800 per cm2), MicroLens provides superior control over output and uniformity. In addition, it provides scalability to large sizes in an ultrathin form factor, and offers the obvious cost advantages of a smaller form factor with fewer components."

MicroLens light guides can be designed for applications requiring extreme thinness, and are currently being developed in sizes under 0.5-mm thick. GLT provides fully integrated edge-lighting modules with LEDs, films, flex circuit or PCB with connector, and MicroLens light guide. With mechanical holding features that can be designed into the backlight, or onto a custom-designed backlight frame, MicroLens edge-lighting modules are designed for easy integration into the host application.

Applications include LCD and keypad backlights for mobile phones, MP3 players, camcorders, digital cameras, PDAs, GPS devices, handheld games, portable DVD players, scanners, automotive interior displays, programmable touch-screen thermostats, home security system controllers, instrumentation and control displays, handheld, notebook and desktop computers and LCD TVs.

GLT said its three Far East production facilities make it possible for the company to offer these edge-lighting modules in production quantities with quick delivery, and the design and engineering capabilities at its Brecksville headquarters provide full custom design, prototyping, test and measurement, and optical modeling/simulation.

Pricing for GLT's MicroLens edge-lighting modules depends upon application, size, and volume, with single-LED edge lights available for well under $1 each.
