Sony showed this giant 82” LCD prototype, which featured LED backlighting and XVycc color space, but you can actually buy a 70” model (for $33,000) with similar technology. A special SXRD rear-projection prototype was powered by a laser rather than a light bulb and was only 10” deep. While there were many claimed advantages of using a laser as a light source, I found something just a bit wrong-looking about the picture on the SXRD prototype. The current SXRDs looked great as did the LCD sets.
