LED backlights slim to EL thickness
Light guide packages are thinner than ever for OEMs who need to meet the increasing consumer demand for smaller, slimmer size with no sacrifice in performance.
The latest LED-based high-brightness backlights from Global Lighting Technologies are claimed to be the slimmest moulded-light-guide units available for backlighting LCDs in a wide array of consumer electronics products, as well as the keypads and keyboards used in mobile phones and laptop and desktop PCs GLT's patented MicroLens light extraction technology and improved manufacturing processes are 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

LED backlight reduces costs and thickness
Backlight design employs side-firing LEDs that focus their light into a high-performance light guide.
High brightness on surface mount LEDs.
Agilent Technologies has introduced a series of surface-mount LEDs designed and qualified specifically for automobile interior and exterior lighting applications.
Backlight assemblies less than 1mm high using light guides as thin as 0.4mm 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 moulded light guides.
"Consumers continually want a smaller size with a thinner, sleeker design", says David DeAgazio, GLT's Director of Sales Worldwide.

"But, of course, there can be no sacrifice in performance".
"To help GLT's OEM customers meet these demands we continually improve our MicroLens light guide technology to maximise the advantages provided by the latest advances in LED technology".
As LEDs have gotten brighter and thinner, so have GLT's moulded-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.
MicroLens light extraction technology provides the most efficient use of today's high brightness LEDs.
The result is light guides that are the world's most efficient edge-lit backlights, with thinner packages that can backlight LCDs from 0.25 to 50in diagonal and higher.
Light is extracted precisely where needed, such as around through-holes for keypads.
MicroLens can reduce the number of LEDs required, providing bright, uniform light in a thinner form factor with no hot spots or dark areas.
That 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 colour.
And, the reduction in the number of LEDs needed can also mean less material required, resulting in lower manufacturing costs for OEMs.
Pricing for GLT's keyboard backlights depends on application, size and volume.
