Abstract

Active matrix organic light emitting diode (AM OLED) display fabricated on a flexible plastic substrates has a potential for being lower cost, lighter weight, lower power and highly rugged with superior image quality, compared to the current glass substrate based AM LCDs. Amorphous silicon (a-Si) technology offers the potential for fabricating the required active matrix backplanes on low temperature (< 150°C) plastic substrates for producing flexible AM OLED displays. We have developed low-temperature a-Si TFT processes, and backplane electronics designs to fabricate and successfully demonstrate AM OLEDs using 4”-size flexible plastic substrates. Flexible AM OLED test displays with sizes up to 2×2-inch and resolutions up to 80 cgpi equivalent have been designed and fabricated. The required enabling technologies and fabrication and evaluation of these displays are discussed.
