Sony has a latest prototype of latest OLED (organic light emitting diode) television which is less than a millimeter thin. This latest model is one third the thickness of its current OLED television XEL-1 and a tenth of its thinnest LCD set.

Sony’s first OLED TV, the XEL-1, was launched at Ceatec 2007 with the thickness of 3mm. XEL-1 has instantly became one of the most talked-about product.

The new TV measures just 0.9mm and based on a prototype 0.3mm screen that Sony first showed earlier this year. The prototype set was shown at the Ceatec 2008 electronics expo in Japan and attracted a steady stream of curious attendees, with many of them snapping pictures of it.

OLED is an emerging flat-panel display technology that uses an organic material that emits its own light, without requirement of backlight and thus means displays are much thinner. The screens also consume less power than competing technologies, handle fast-moving images better and offer good color reproduction.

Sony still faces production problems in making larger screens, so there’s no word on when the larger TV set will be launched.

The 0.3mm panel is based on the same screen that’s used in the XEL-1. By carefully grinding down the glass substrate the panel is made thinner but also much more brittle. There were also no details of when the even-thinner 11-inch set might hit the market.
