"Samsung Electronics has developed what it says is the world's first organic light emitting diode (OLED) display that measures 40-inches across the diagonal. OLEDs have been viewed as a potential replacement for LCDs and PDPs (plasma display panels) in some applications for several years. They don't require a power-hungry backlight and so are viewed favorably for portable applications. Generally faster response rates of OLED screens means they are also being considered for use in televisions. The new display is about four times the size of its nearest competitor, a 21-inch prototype that was announced in January by Samsung Electronics. Prior to that panel, the largest had been a 20-inch prototype produced by Japan's Seiko Epson. The Japanese company had also produced a 40-inch panel in the past but had done so by combining 4 of its 20-inch panels to create a larger screen. The new Samsung prototype is a single panel." If OLED is the future, Samsung really has positioned themselves as the leader. The amount of development that has occured with OLED in the past year is amazing and it can only be a short while before they start taking over from LCD and possibly even Plasma.
