The most advanced OLED technology in the industry
OLED Display Overview
Nowadays, as the information society advances dramatically and electronic devices are required to carry out ever more sophisticated functions, electronic displays are growing in importance and act as the interface to our lives.
We have been developing and manufacturing a new type of display device, the organic light emitting diode (OLED) display, which meets the stringent requirements of this new age. OLED displays have many excellent characteristics, including sharp, bright graphics, a wide viewing angle, low power consumption and fast response as well as being extremely thin.
※ Pioneer Group early focused its attention on the practical applications of OLED, which was introduced by Mr. C.W. Tang's study group in 1987, and made an early start in OLED research and development. By 1997 we, the former "Yonezawa Plant" of Tohoku Pioneer Corporation, had succeeded in the world's first mass production of OLED displays. Since then we have expanded its OLED display market into cellular phones, Pioneer's in-car audio systems as well as various other applications. We will use this accumulated experience, expertise and technology to provide our customers with the most advanced, high value OLED displays.
What is OLED?
OLED displays produce higher contrast images, have a wider viewing angle, faster response and are thinner and
more lightweight compared to conventional displays.
When a direct current is applied to the device, holes with positive charges are injected from anodes and electrons with negative charges are injected from cathodes into the organic light emitting layer.
Then, the organic molecules emit light when the positive hole and the negative electron couple and generate energy in the organic light emitting layer.
Because most of the organic materials are isolators and are difficult to conduct current, organic light emitting layers need to have very thin structures, approximately 0.1um.
