Future of the Screen: After the CRT, a Display Deluge
While the LCD-backlit LED has so far brought incremental advances to the mobile-computing space, the place where it's poised to have the most dramatic impact is in televisions. A high-end LCD HDTV has a contrast ratio of about 30,000:1, whereas LED LCDs have contrast ratios between 1,000,000:1 and 2,000,000:1. Power consumption and weight savings of LED-backlit LCDs are between 30 and 50 percent, and these savings translate into very attractive form factors—the latest LED LCD TVs from Sharp and others are only a little over 1 inch thick, despite their large (46 inch and up) screen sizes.
