Backlight assemblies <1mm high utilizing 0.4mm thin light guides are now a reality
(Technology News, 12 May 2008 )
Global Lighting Technologies has introduced LED-based high-brightness backlights that have a thinness of 0.4 mm or less to provide very slim molded light guide BLUs for backlighting LCDs in a wide array of consumer electronics products, as well as the keypads/keyboards used in mobile phones and laptop and desktop PCs.
GLT’s patented MicroLens light extraction technology and improved manufacturing processes are said to be making light guide packages that are thinner than ever available to OEMs who need to meet the increasing consumer demand for smaller, slimmer size with no sacrifice in performance.
MicroLens can reduce the number of LEDs required, providing bright, uniform light in a thinner form factor with no hot spots or dark areas. This means smaller and thinner LCDs and keypads for smart phones and other handheld devices, as well as thinner laptop and desktop PC LCDs, with keyboard backlighting of outstanding thinness, luminance and uniformity in virtually any color. And, the reduction in the number of LEDs needed can also mean less material required, resulting in lower manufacturing costs for OEMs.
