May 19, 2008—A GreenTV logo program to help focus LCD TV manufacturers and brands on reducing the power consumption of LCD TVs and raising consumer awareness has been launched by the LCD TV Association, a global, not-for-profit, marketing trade association for the entire LCD supply chain, retail channel, and consumers.
“We believe LCD TVs already consume the least energy to build, use, and dispose of, but we want to make them even better in the future and have a lighter ‘carbon footprint’ on the Earth by having the most recyclable parts and highest possible energy efficiencies. This will involve the use of less heavy metals, ambient light sensors, and smarter electronics very soon, as well as more LED backlights with spatial and content-based dimming and energy savings over time, and many other improvements,” noted Bruce Berkoff, Chairman of the LCD TV Association.
The first step in the LCD TV Association’s GreenTV Program is to work with major TV vendors to implement and promote ambient light sensors, which will automatically lower the set brightness in a dark room by decreasing power to the backlight—thus saving energy and also reducing potential eyestrain, notes the group.
Participants in the program will gain the right to use the association’s GreenTV logo on products, packaging, and advertising material.
The US Department of Energy (DOE) has estimated that in the US alone, over 4 Terawatt-hours of electricity were consumed by TVs in 2005. The Environmental Protection Agency (EPA) will introduce their Energy Star program for flat TVs by the end of 2008, taking into account the use of this type of ambient sensor to save energy.
