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 [email protected] _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-chat To unsubscribe, send any mail to "[email protected]"
