Ink-jet and a-Si TFT technologies are the best combination for fabricating a large-sized and low-cost OLED display. We developed a 2.1-inch, full-color polymer AM-OLED display driven by a new current-programmed method using a-Si:H TFTs showing more than 450 cd/m2 brightness, more than 100:1 contrast with real black and about 5 % deviation of half-tone uniformity, which were achieved using a new polymer OLED structure by inserting the interlayer into the conventional 2-layer LEP structure.
