New LED Backlights For LCD Screens

Posted by timothy on from the you-can-never-have-too-many dept.

Benefits include longer battery life for notebooks, less weight, and a larger color gamut (up to 130% of the NTSC standard). The release can be found here." I wish I could hook up one of their evaluation kits to my machine right now;) The same site has quite a lot of LED-related information throughout.

    I think this would make a very cool addition to a mobile mp3 player. Instead of the little screens they have now, we can get some larger ones with better GUIs, due to much lower power usage.

    Their power-saving plan works by alternating the duty cycle of their red, green, and blue LEDs at 1-65Hz. I can feel a headache coming on already.

      If at 85 hz you still notice flicker, then you have a really hyper nervous system. I have an unusual form of epilepsy, which means that if there's ANY flicker, I can feel it, like how you can feel somebody's standing behind you, without being able to see them. It's my special power :) And at 80 hz I don't feel any flicker from my screens. 75 hz though, that still flickers noticeably.

      As far as flicker with TV's is concerned. The current evolution is totally wrong. TV's are getting the same type of screens as PC's. Screens which light up for a lot shorter timeperiod when illuminated, which means they're black more of the time than old TV's, so they flicker more noticeably. If you want a flickerless TV, get yourself one of those big-ass really old TV's that had a nice afterglow. (It seems the bigger they are, the less the flicker, which I can't explain) Much easier on the eye. Or get yourself a 100 hz TV, those don't flicker either, but they cost an arm and a leg.

      Or, you could just do like I did and get yourself a decent computer screen (as in big, flat, and with a low dot pitch) and a TV card, and then hook that all up to your stereo system. The quality is far superior to anything you can get from a TV, and the sound is very nice too. Plus, you can take screenshots of something stupid as it happens :)

      It might become a problem to use that as the family TV though. But you could use an old PC as the TV, since all you need is a PCI bus and a reasonably decent PCI graphics card (that can drive the screen at 80 hz or higher in 800x600). The images get copied over the PCI bus to the graphics card, so your cpu doesn't get involved, which means that you could even use a low-end pentium for it.

  3. X-Mas Tree Lights by Anonymous Coward · · Score: 2, Interesting

    Wish one of these companies would get a clue and do Christmas tree lights. Extreme low power, long life compared to current plugins (skip the plug-in and go with a straight built) and possibly programmable. Yeah a string might cost $30 but would be paid for in 1-2 seasons . Any of you looking at your Electrical cost?

    OLEDs are the future. Backlighting is irrelevant.

  5. Is it possible to use these in my home? by Anonymous Coward · · Score: 1, Interesting

    Is it possible to replace regular light bulbs and floresents with these Luxeon Star LEDs? Better power savings and more stable white color, but what would the cost per light fixture be?
