I believe local dimming LEDs are where we are today. Large sized affordable OLEDs are too far away right now.

I'm actually surprized that the trend this round was more 120hz displays instead of LEDs with local dimming.]]>May 6th 2008 7:12AMhttp://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/http://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/May 6th 2008 9:11AMhttp://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/http://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/May 6th 2008 9:30AMhttp://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/http://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/May 6th 2008 12:58PMhttp://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/http://hd.engadget.com/2008/05/06/auto-brightness-to-be-the-first-step-in-lcd-tv-green-status/
IRIS, and sony's ACE, and other implementations of dynamic contrast will continually adjust the backlight according to whats on the display. Where it gets confused is when the tv displays a bright white and deep black at the same time.

Turn both dynamic contrast AND light sensor on, and you get unpredictable and uncontrollable results.]]>May 6th 2008 1:25PM
