Caltron launches ‘HBT-1212O’ Open Frame High Bright LED Backlit Monitor

Many outdoor digital signage applications are exposed to a great
amount of ambient lighting or sunlight. With Caltron’s new HBT-1212O,
high bright open frame LED monitor that is rated at 1600 nits will be
perfect for any application that is constantly surrounded by ambient

Industrial-grade LED backlights provide better
readability in ambient light conditions for digital signage and
advertising, says Caltron Industries, a leading provider of LCD
open-frame monitors. Starting in 2010, Caltron will offer LED-backlit
technology in digital signage, such as the 1600 nits (candle light per
square meter) brightness system in Caltron’s 12.1" High Bright LCD Open
Frame Monitor (HBT-12120). This provides a brightness level five times
greater than CCFL technology while reducing cost of ownership.

"LED backlights are more powerful and more cost-effective for
digital signage than CCFL backlight tubes," says Jim Wang, President of
Caltron Industries. "They are perfect for digital signage advertising,
outdoor presentation systems, or any other situation with high ambient
light conditions."

Most off-the-shelf LCD monitors have a brightness rating around 300
nits — a level with insufficient luminance for outdoor or
bright-environment viewing that creates a grainy, low-quality image.
The traditional solution is the costly installation of multiple CCFL
(light bulb) backlight tubes. However, this also requires a thermal
management solution to dissipate excess heat generated from backlights.
Cumulatively, all of these upgrades create an arduous and costly
process. The smarter, more-affordable alternative is an LED backlight.

"CCFL solutions require cost-heavy thermal management, like heat
exchanges, piping, or cooling fans. When the goal is simply good
visibility in ambient light, that’s a lot to ask for," says Wang.
"Caltron uses LED backlights for digital signage because it makes sense
for the operator and the viewer. It’s cost-effective, easy to use, and
it works well in almost every circumstance."

In 2010, Caltron will introduce its line of open-frame
high-brightness industrial monitors. Caltron has partnered with leading
high-bright panel suppliers on the best backlight solution possible
through seven years of research and development, all leading to the new
LED backlight technology as featured in the HBT-12120. This technology
has undergone rigorous testing, including nearly 10,000 hours of
backlight aging tests. The net result is a 1,600 nit high-bright screen
that consumes less than 24 watts (about half of similarly equipped CCFL
backlit panels) for lower power consumption without any loss in
brightness or MTBF (Mean Time Between Failure).

"Our R&D testing shows that LED backlights are reliable,
durable, and cost effective," says Wang. "This technology introduces a
better way to take clear digital signage outside and in other
high-ambient light areas, and we will be soon be integrating it into
our other products."

Caltron’s 2010 product line starts with the HBT-12120 monitor. In
the coming months, the LED backlight technology will expand into
Caltron’s other open-frame products. For complete product details,
