GLT Introduces LED-Based High-Brightness Backlights

Global Lighting Technologies (GLT) has introduced LED-based high-brightness backlights that offer thinness – down to 0.4 mm or less – to provide the slimmest molded light guide BLUs available for backlighting LCDs in a array of consumer electronics products, as well as the keypads/keyboards used in mobile phones and laptop and desktop PCs. Backlight assemblies less than 1 mm high utilizing light guides as thin as 0.4 mm or less are now a reality. The result is BLUs that offer the thinness of electroluminescent (EL) backlighting, but with all the advantages of today’s advanced LEDs combined with the superior light extraction provided by MicroLens molded light guides. As LEDs have gotten brighter and thinner, so have GLT’s molded light guide BLUs, thanks to continual refinements of the company’s patented MicroLens light extraction technology, along with superior optical design, prototyping, and manufacturing processes at three Far East facilities.



The MicroLens light extraction technology provides utilization of high brightness LEDs. The MicroLens can reduce the number of LEDs required, providing bright, uniform light in a thinner form factor with no hot spots or dark areas.
