In time, IBM suggests the new technology will bring its unprecedented resolution to smaller displays, such as those found on laptop computers and handheld computing devices. Sanyo Electric Co. Last year, Kodak and Sanyo Electric unveiled a jointly developed 5.5-in. Smaller versions of Kodak's OLED technology are already in the field in mobile phones and automotive audio equipment. The displays offer a high-speed response to data, up to 1,000 times faster than LCDs, to deliver smoother moving images on screen. Other benefits include a brighter, richer color, and the ability to be viewed from multiple angles without backlighting.
Images are sharp and have high contrast.
Thinness and low-power requirements afford design flexibility for portable devices such as mobile phones and pagers. Three-Five will also supply the necessary ASICs to drive the displays. Universal Display Corp., Ewing, N.J., continues to advance its OLED display technology and announced several new patents over the previous year, acquired with its research partners, Princeton University and the University of Southern California. One patent relates to the structures that employ a blocking layer for enhanced OLED efficiency using phosphorescent dopants, a technology that Universal has pioneered. A second relates to OLED structures having angled-walled mesas resembling truncated pyramids that reflect light out of the structure, increasing the efficiency and brightness of the display.
