Dupont targets OLED display mass production

Dupont and Dainippon Screen Manufacturing will form a strategic alliance to develop mass production techniques for organic light emitting diode (OLED) displays, according to an announcement made in Japan.

The focus is on developing better processes and printing equipment for the fabrication of OLED displays.

OLEDs are attracting interest because the panels are paper thin but offer extremely high-quality images, superb color saturation, and fast response times. And they draw little power because they don't require a backlight.

At the same time, they face durability challenges. The organic matter used to illuminate the image can by ruined by the … Read more

Report questions Sony's next-gen TV claims

Sony appeared to be on the verge of starting the next revolution in TV technology last year when it introduced its first OLED television, most notable for its paper-thin screen. The display, which uses bright and low-power organic light-emitting diodes, appeared so promising that the prospects for LCD and plasma TVs were soon called into question.

A new study, however, may cast that future in a different light. A research firm called DisplaySearch tested Sony's XEL-1 TV and found that its brightness began to degrade significantly after 1,000 hours--translating to a loss of half its original quality in … Read more

Sony EL display is paper thin

There's thin. Then there's paper thin. Sony showed an electroluminescent (EL) display that's print-paper thin at the Display2008 conference in Tokyo.

The Sony EL display is based on organic light-emitting diode (OLED) technology that uses electroluminescent organic materials. OLED panels are extremely thin because they don't need backlights. The electroluminescent layer contains a polymer substance that directly converts electricity to light.

The panel shown this week at Diplay2008 is about 0.3mm thick, besting Sony's current 1.4mm-thick EL TV (photo). Epson lists its Premium Glossy Photo Paper as 0.3mm thick. So by this … Read more
