Sanyo has developed what they claim to be the world' smallest high definition (1920x1080) display. Coming in at 7.1 inches, the display, which is an LCD, is designed and optimized for mobile devices. To that end, the HD display's innards are designed to keep power consumption as low as possible. In other small display news, Sanyo has also developed a 2.6-inch display that supports up to XGA resolution, or 1024x768. Expect to eventually see this in cellphones. 

Smaller displays, higher resolutions... what more could you want? (Unless you're a hippie and want peace or something.) - Nicholas Deleon
