Epson invents new long-life OLED display system… the ultimate black

Seiko Epson Corporation has recently developed an organic light-emitting diode (OLED) display system, capable of producing “the ultimate black.” Having resolved the problem of achieving long life for the device, a longstanding challenge with OLED, Epson has put into operation a manufacturing line for small-scale production of OLED for practical applications. This new technology by Epson offers a new solution that makes effective use of advanced image representation not possible with conventional flat panel displays (FPD).

The light emitting capabilities of OLED displays make possible such features as high contrast, wide viewing angles, and fast response times. In addition, the display can be made very thin and lightweight, making this new device a promising candidate for next-generation flat panel displays. However, in order to make the device viable for practical applications, it was critical to find a solution to a number of technical problems, including how to give the device a longer life. It has screen size of 20.3 cm diagonal (8 inches) with 800 x 480 (W x H) number of pixels at a brightness of 200 cd/m2, which is augmented with a high contrast ratio of 100,000: 1 or greater.

Epson has already installed and commenced operations of a development and manufacturing line that is capable of small-scale production at its Fujimi Plant in Nagano prefecture, Japan.
