Using 160 white LEDs to backlight the LCD screen, Eizo Nanao Corp managed to cut power consumption by 72%.

When you consider that a simple 19-inch LCD screen uses about 34W in it’s average daily use, dropping it down to about 9.5 is an incredible step down. It’s like if next years model of your gas-guzzling SUV came out with a minor addition which made its MPG jump from 18 to 31. It also comes with another great energy-saver. “The monitor also features an “Auto EcoView” function that automatically adjusts the backlight’s luminance in accordance with the external brightness detected by the luminance sensor equipped on the bottom of the monitor.” This way the screen will always be bright enough to see, but not so bright that it will melt your eyeballs along with the polar ice caps.

Although it may be more difficult to position LEDs into big-screen LCD TVs (due to the increased area), I wouldn’t be surprised to see some hitting the market in the next year or so. Especially when you consider “a newer 20-cu.-ft refrigerator cost approximately $50 annually to run, and a 50-inch 1080p plasma set costs approximately $110 annually.” Our appliances need to reduce power consumption down just as much as our cars do.
