3mm. That’s how thin the SONY XEL-1 ultra thin high definition television set is. Made out of organic light-emitting diodes (OLEDs) the HD TV sports an 11 inch screen, 960 x 450 resolution, HDMI input, USB and Ethernet, two 1W built-in speakers, and an unbelievable 1,000,000:1 contrast ratio. Can you imagine the black colors? The subtlety of the shadows? And HD to boot!
