Green Screen: Revised IEC Standard Will Help Consumers Choose Energy Efficient Televisions

New York, Nov 09, 2007

According to Energy Star, a joint program of the U.S. Environmental Protection Agency and the U.S. Department of Energy, television use makes up approximately ten percent of a household's annual electricity bill. In 2002 the International Electrotechnical Commission (IEC) published IEC 62087, Methods of measurement for the power consumption of audio, video and related equipment, a standard that helps to determine the amount of power used by televisions and other home electronics.

Rapid advances in television technology underscore the need for revisions to IEC 62087. For example, traditional cathode-ray tube and plasma television sets, which were prevalent at the time of the standard’s development, require more electricity to produce brighter images. Today’s flat-panel LCDs and rear-projection microdisplays consume the same amount of power regardless of image brightness. A reliance on static images as a test of power consumption and a lack of discussion on power saving features also limit the standard’s continued applicability in today’s marketplace.

Power Saving Tips
  • Turn the TV off when it's not being used

  • Turn down the LCD's backlight

  • Turn on the power-saver mode

  • Reduce light output with other settings

  • Control room lighting

  • Buy a smaller screen

  • Watch TV with family and friends

  • Reduce overall time spent watching TV

Updates to IEC 62087 are expected to be published in early 2008. The revisions will incorporate tests for power saving features and will address power consumption in a variety of different modes, from live-action images and recording functions to stand-by, disconnected, and off modes.

The revised standard will also reflect the marketplace’s increased demand for energy efficient electronics, helping manufacturers provide accurate energy label ratings, aiding consumers as they shop for efficient products, and reducing overall green house gas emissions.

IEC Technical Committee 100, Audio, video and multimedia systems and equipment, developed IEC 62087 and is currently working on the standard’s second edition. IEC TC 100 is chaired by Mark Hyman of the Society of Motion Picture and Television Engineers, an accredited standards developer of the American National Standards Institute (ANSI). The committee publishes international standards consumer products and professional equipment ranging from digital video players to plasma technology and mobile communications. TC 100’s work addresses interfaces, interconnections, and interoperability between systems, as well as testing and measuring methods.
