Sony XEL-1 OLED TV / 2008
On paper, the first commercially available OLED TV doesn’t seem all that impressive. The screen was only 11 inches, it cost $2,500, and the picture wasn’t even 1080p high-def. In person, however, the XEL-1’s super-slim profile—just 3 millimeters—and ultradark black levels were unlike any other boobtube on the market. Now, OLED is the standard for smartphone displays and flagship flat-screen HDTVs.
