HP Introduces New Technology to Save Mobile Battery Life

Posted by CowboyNeal on from the batmax-beware dept.

fenimor writes "HP researchers have developed new technology to save battery life on mobile devices. Targeting one of the main culprits of battery consumption -- the display -- they've developed an energy-aware solution that dims parts of the screen that aren't in use. Display battery life lasts from two to 11 times longer, depending on what the user is doing."

    Now, this is the kind of thinking and research development that I would expect from HP!

    What? They're not supposed to just buy up some half-baked company that's struggling with quality issues and try to merge the two disparate entities together using words like "Synergy"?

    Dang. It is a rebirth of HP!

  2. LCDs and Dimming by Anonymous Coward · · Score: 5, Interesting

    You can't dim a 'portion' of a standard LCD monitor; the monitor is backlit by small flourescent tubes at the top and the bottom of the display, and it is those that take most power to drive. On desktops they have multiple tubes at the top and bottom (and you could shut one or two off to save power), but for notebooks they usually have only one, and by dimming that one you end up dimming the whole display, not a portion of the display.

    If they can light up only a portion of the screen they must be using white LEDs or something like that where they can light up as many or as few as they want. If this is the case, i wouldnt hold my breath as to when it will reach the market.
