Brecksville, OH, March 2006 – A new family of single-LED
molded light guides using Global Lighting Technologies’ patented
MicroLens™ technology provide higher brightness than other
LED based backlighting solutions – with greater efficiency,
reduced part count and lower cost – for a wide variety of
applications.
GLT’s MicroLens™ backlights can be designed in sizes
from 0.24” diagonal to 15.4” diagonal to provide single
LED monochrome, bi-color or tri-color backlights. Applications include
microdisplays used in digital still cameras and camcorders, Gen
3 mobile phone displays, PDA keypads, programmable touchscreen thermostats,
home security system controller keypads, fish finders, instrumentation
and control displays, automotive interior displays, and even desktop
monitors.
MicroLens™ pixel-based light extraction technology provides
the most efficient utilization of today’s LEDs, making it
possible to offer fully integrated backlighting modules with higher
brightness, crisp color, extreme thinness (to 0.60 mm or below),
outstanding uniformity (approx. 80-85% on average), lower power
consumption (typically 1-20 mA @3.5 V), and the obvious cost advantages
of a smaller form factor with fewer components.
MicroLens™ molded light guide backlights utilize the most
advanced and efficient light extraction technology, providing a
unique "transition" area that spreads the light uniformly,
extracting light precisely at each point across the panel. MicroLens™
light guides are developed in a very thin package, with mechanical
holding features that can be designed into the backlight, or on
a custom-designed backlight frame. This allows chip-on-glass (COG)
or chip-on-flex (COF) LCDs or the entire display assembly to be
easily mounted into the host application. This can reduce part count
and assembly and material costs.
“For most applications, we provide a total backlight solution
with LED, films, flex circuit or PCB with connector, and, of course,
our MicroLensTM light guide,” said David DeAgazio, GLT’s
Director of Sales Worldwide.
GLT’s three Far East production facilities and in-house tool
making make it possible for the company to offer these custom backlighting
modules in production quantities with quick delivery. The extensive
design and engineering capabilities at its Brecksville, Ohio, headquarters
offer customers full custom design, prototyping, test & measurement,
and optical modeling/simulation.
Pricing for GLT’s high-efficiency single-LED backlights is
highly dependent upon size, design, and annual volume. However,
simple single-LED backlights can be purchased in quantity for as
little as $1.00 or less. For details, contact Global Lighting Technologies
