It's called local dimming. That's a TV feature where the LEDs are positioned behind the panel and grouped into a number of tiles whose lighting can be controlled independently. I can't find hard figures on the number of tiles, but we're talking dozens, maybe a few hundred--compared to millions of pixels. I'm not aware of a computer monitor using local dimming, but I haven't been paying particular attention to that area. -- Christian "naddy" Weisgerber naddy@mips.inka.de
