It seems like every time one turns around there’s a new development in the LED/display kingdom. Something either gets brighter, smaller, cheaper, or thinner. Well, why should today be any different.
Using mixed oxide thin-film transistors, researchers at the Flexible Display Center (FDC) at Arizona State University, in conjunction with Army Research Labs scientists, claim to have created the largest flexible OLED display, and in color no less. The display measures 7.4 inches diagonal, which does not sound like a lot, but according to Nick Colaneri, director of the FDC, "This is a significant manufacturing breakthrough for flexible display technology. It provides a realistic path forward for the production of high performance, flexible, full color OLED displays, accelerating commercialization of the technology in the process."
The largest flexible OLED display relies on mixed oxide thin-film transistors.
The FDC has found that mixed oxide thin-film transistors provide a cost-effective method for making high-performance color displays capable of high switching speeds and low power consumption. Also, mixed oxide thin-film transistors can be made on existing amorphous silicon production lines, eliminating the need for special equipment and processing. As a result, the OLED display meets targets set by the US Department of Defense to accelerate the development of full-color, full-motion video flexible OLED displays for use in thin, lightweight, bendable, and rugged devices.
