Dual benefits of ambient light sensing technology for flat panel TVs outlined in consumer white paper.

Plano, TX– Texas Advanced Optoelectronic Solutions, Inc. (TAOS) has announced that the company is providing key technology to the HDTV industry that is directly benefiting consumers who purchase flat panel display HDTVs. 

A recognized leader in ambient light sensing (ALS) technology, TAOS, is championing the use of ALS sensors in flat panel TVs (both LCD and plasma) to provide improvements in display picture quality while simultaneously conserving energy by reducing power consumption, thereby reducing the consumer’s annual utility bill. 

For more than a decade, TAOS has used of ALS sensors in a broad range of consumer electronic products from mobile phones to notebooks/laptops to digital cameras/camcorders to portable MP3/DVD players to video games.

As a member of the LCD TV Association, TAOS is working closely with its other members to promote ALS sensor use in HDTVs and encourage TV manufacturers to participate in the Association’s Green TV logo program. 

Launched in 2008, this program promotes “green technology” and global energy conservation, currently through the implementation of ALS sensors in LCD TVs to automatically adjust TV set brightness in response to ambient room brightness, thereby reducing system, power consumption by at least 30 percent.

TAOS has developed a white paper for consumers titled “Turning HDTVs Green” -- which is being distributed to media outlets on a nationwide basis – that provides an overview of the HDTV industry, the changes that are driving the need for increased energy conservation and describes existing technologies such as automatic brightness control which uses the TAOS automatic – or ambient – light sensing to provide the dual benefits of improved display picture quality and increased energy-efficiency in flat panels TVs.

“When purchasing an HDTV, the consumer primarily cares about big-screen picture quality and price. TAOS automatic light sensing (ALS) technology delivers in both areas by automatically adjusting the HDTV display brightness to suit the surrounding light levels and providing a proven and highly cost-effective solution that also reduces energy consumption and the consumer’s overall utility bill,” says Jerry Koontz, TAOS, Inc. Director of Marketing.

  • ALS is not going to do much to deal with power consumption during viewing and nothing for power draw that continues even after the TV's are turned off. Plasma uses more power than CRT televisions and should be banned. A lot more power is needlessly used than with the about to be banned tungsten lamps in people's homes. Actually surprised that so few people pick up on the not surprising fact that plasma displays with their internal heat have much shorter component lives and are much more likely to need to be repaired. With replacement system boards selling for $800-1500, or the price of a new TV, there will be a lot of plasma and DLP sets going into the landfills over the new 5 years. Green certification should require that manufacturers provide a 5-year parts and labor warranty to keep their products out of the landfills and the televisions should be designed for easy and full recycling (has worked in Germany for years). This is really a failure of product design engineers when they do not design for the entire product life including its end of life recycling. We still design and manufacturer with a 1950's mentality.
