Philips Turns Off Aptura Backlight

Philips has decided to say goodbye to the initial version of its Aptura TV-backlighting technology. As Philips explained, it used "high-output fluorescent lamps, operated in scanning mode." In effect, the backlight blinked rapidly. This, Philips said, would "cancel out the sample-and-hold effect, which is characteristic of LCD technology," thus reducing motion smear. Better contrast was another benefit, as the backlight dimmed for dark scenes, and worked in tandem with video processing to reduce light leakage. The "deep dynamic dimming" also increased viewing angle. Philips has long been selling non-switching backlit TVs in its Ambilight line, and plans to explore a new and little-used backlighting scheme using LED technology. Philips already markets LED products through its lighting division. (Thanks to Geoff for spotting this one.)
