Any one try White LED as the the backlight for the lcd display.

ya, i replaced my backlight with 2 rails of bright white leds...works just as well as the CCFLs.

I thought that this would interest the LCD modders - looks like someone at Intel is thinking along the same lines.

Dear Friends，
Japanese company SHARP has just released some samples about a new type of Light sensor embedded LCD screen, it has one Light sensor pixel embedded along with 3 color pixels, so it can scan pictures while displaying. I saw they made a demo of GIS related application(multi-touch enabled, Gesture control), and I believe this can be a revolution to hand-hold Electrionic Entertainment devices.
