Sony OLED TV Showcased
Sony was one of the exhibitors at Display Expo held in Japan just last week and of course they showcased their OLED TVs. One of them was a prototype 21 inch OLED panel with 1366 by 768 resolution. The contrast ratio is the same as my XEL-1 which is 1000000 to 1. The design has dramatically changed and looks futuristic in a way with the stand fully integrated.

The XEL-1 OLED TV
In October 2007,Sony introduced the world's first OLED TV - the XEL-1. This first model is a highly priced (~2,500$), small sized (11") Television - more of a commercial-prototype than anything else, Sony only makes around a thousand units a month.
Sony's 27" OLED - the XEL-2?
Sony announced in May 2008 that they are working on a new TV. This one will be a 27" model - which is large enough to be called a television indeed. Sony even showed us a prototype of that screen (picture on the left).
Sony's 21" OLED prototypes
In April 2009, Sony displayed a new 21" OLED TV prototype. These TVs have a 1366x768 resolution, 1,000,000:1 contrast ratio and they are only 1.4mm thick. Will this be the XEL-2 TV?

Organic light-emitting diode
An organic light emitting diode (OLED), also light emitting polymer (LEP) and organic electro luminescence (OEL), is any light emitting diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds. The layer usually contains a polymer substance that allows suitable organic compounds to be deposited. They are deposited in rows and columns onto a flat carrier by a simple "printing" process. The resulting matrix of pixels can emit light of different colors.
Such systems can be used in television screens, computer displays, small, portable system screens such as cell phones and PDAs, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. OLEDs typically emit less light per area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.
A significant benefit of OLED displays over traditional liquid crystal displays (LCDs) is that OLEDs do not require a backlight to function. Thus they draw far less power and, when powered from a battery, can operate longer on the same charge. Because there is no need for a backlight, an OLED display can be much thinner than an LCD panel. Degradation of OLED materials has limited their use so far.[1]
