Organic LEDs: The Future of Faster, Brighter, and (One Day) Cheaper TVs.
If you've looked into buying a TV lately, you are familiar with the alphabet soup that seems to come with choosing even the most basic model: HDTV, 1080p, LCD, NTSC, and more. But before you give up the whole thing in frustration, here's one more acronym that could make your choice a lot easier: OLED.
The innovative thing about OLEDs (for organic light-emitting diodes) is that lots of tiny OLEDs can be "printed" onto a single big sheet, allowing engineers to make a digital display that uses less power than a plasma screen and offers higher contrast, a wider range of viewing angles, and richer colors than an LCD screen.
Already used in cell phones and other small devices, OLEDs were not initially employed in TVs because of a short life span of only a few thousand hours of use. But now Sony has announced the XEL-1 (pictured above), the first OLED-based TV. Currently available only in Japan and the United States, it has a price tag of almost $2,500 and a modest 11-inch screen. Still, if OLED manufacturing continues to improve, TV screens as large and as slim as those in old home-movie projection systems may become common.
