The world's largest OLED display was introduced by Toshiba Matsushita Display Technology Co. this week. Organic Light-Emitting Diode displays are now a whopping 20.8 diagonal inches in size.
This low-temperature poly-silicon (LTPS) OLED display was created using newly developed techniques for uniform coating of organic electroluminescent materials and the optimized combination of electrodes and organic materials.
The three (RGB) color-emitting layers use polymer organic electroluminescent materials, and an ink-jet type coating process is adopted for coating of each color. These have contributed to achieving a large screen size of 20.8-inch and would enable the expansion of potential applications of large-size OLED panels. Note also the very high resolution of this OLED display - 1,280 x 768 pixels.
Science fiction fans have great hopes for OLED technology. Soon, we will have the flexible wall sheet displays we've been waiting for since 1958, when E.C. Tubb published his very cool novel The Mechanical Monarch.
Against one wall a wide sheet of clear material suddenly flared with light and swirling colour. It steadied and a woman stared from the screen...

OLED is a very cool (almost science-fictional) material; it has a variety of advantages over conventional flat displays:
The polymer layers of an OLED are thinner, lighter and more flexible than those of an LED or LCD; this flexibility provides a wider range of applications over brittle LCDs.
OLED displays are brighter than LEDs and LCDs; because they are thinner, OLEDs pass more light.
OLED displays do not require backlighting; they consume much less power, making them ideal for use in small devices like PDAs, iPods and mobile phones.
It seems likely that OLED displays will be cheaper to make in larger sizes.
OLED displays have larger fields of view - up to 170 degrees.
