OLED是一种非常有前景的平板显示器，它的优点主要有：
- 高对比度
- 宽视角
- 快速响应时间
- 可以做得非常轻、薄
OLED的寿命是个问题，Epson今天能够达到的指标是5万个小时，基本上达到实用的要求。
Epson Develops Long-life OLED Display System Capable of Reproducing 'the Ultimate Black'
Seiko Epson Corp. has 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, alongstanding challenge with OLED, Epson has put into operation amanufacturing line for small-scale production of OLED for practicalapplications.
Epson will exhibit this newOLED display system at FPD International 2007, an internationalexhibition of display technologies to be held at Pacifico Yokohama fromOctober 24. This new technology by Epson offers a new solution thatmakes effective use of advanced image representation not possible withconventional flat panel displays (FPD).
The light emittingcapabilities of OLED displays make possible such features as highcontrast, wide viewing angles, and fast response times. In addition,the display can be made very thin and lightweight, making this newdevice 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.
As high-quality image representation lies at the heart of OLEDdisplays, above and beyond what is possible with conventional flatpanel displays, Epson determined that this was precisely the featurethe company should pursue. To realize the requisite high-qualityrepresentation of textures, Epson has been uncompromising in itsefforts to achieve "the ultimate black", since it is black that holdsthe key to overall image quality.
Furthermore, the problem of early stage brightness deterioration,until now a major obstacle to extending the life of the device, wassolved by improving the light-emitting materials and through thedevelopment of Epson's own original element structure. As a result,Epson was successful in lengthening the life of the device to more than50,000 hours, a level appropriate for practical application. Futureplans call for Epson to develop various displays with OLED systems fordifferent uses, and study their potential for commercialization.
Epson has already installed and commenced operations of adevelopment and manufacturing line that is capable of small-scaleproduction at its Fujimi Plant in Nagano prefecture, Japan.
From now on, Epson will accelerate its efforts to develop uses forOLED display systems that make use of advanced image representation andnurture them into businesses. |
