Brecksville, OH, May 2003 – Global Lighting Technologies
(GLT), Inc. has introduced a family of new light guides using its
patented MicroLens™ technology that provide superior performance
and cost efficiency for backlighting LCDs used in portable/handheld
devices such as cell phones, PDAs, and handheld PCs.
For color cell phones, GLT offers a new backlight assembly with
an output display area of 30 mm wide x 22 mm high and a thickness
of only 0.8 mm. It outputs a luminance of >3000 cd/m2 for a 1.5”
diagonal screen, while utilizing only two high-brightness white
LEDs @ 15 mA, making it extremely cost-effective. Pricing is $0.75
to $1.25 each with brightness enhancement films (not including LEDs),
depending on final construction.
GLT’s new PDA backlight assembly utilizes four white LED
backlights for an output display area of 45 mm square and provides
a brightness of >2000 cd/m2 to a 2.5” diagonal screen.
It includes LEDs, metal frame, molded plastic light guide, flex
circuit and brightness enhancement films, and costs approx. $6.00,
depending on final design.
GLT’s MicroLens™ technology enables mechanical holding
features to be designed into the backlight, allowing COG or COF
LCDs – or the entire display assembly – to be mounted
into the host application, reducing part count and assembly time
and resulting in overall savings. It allows the LEDs to be molded
directly into the light guide, and makes the backlights more efficient
and less power intensive.
A new light guide assembly for CCFLs has also been introduced by
GLT for backlighting LCDs used in handheld PCs, games and a variety
of diagnostic and monitoring instrumentation. Only 3 mm thick, with
an output display area of 83 mm x 155 mm, it utilizes an L-shaped
CCFL to provide a luminance of 6500-7000 cd/m2 for a 7” diagonal
screen, with full VGA color. Bulb current is only 6 mA.
“Our new CCFL light guide uses MicroLens™ to provide
higher efficiency and superior brightness with no increase in power
consumption compared to traditional LCD backlighting,” said
David DeAgazio, GLT’s Director of Sales Worldwide. “And,
it provides exceptional uniformity across the entire viewing area.”
