Fabrication of Polymer TFT Arrays on Plastic Substrates Using a Low Temperature Manufacturing Process

In this paper, fabrication of a $60{\times}48$ polymer TFT array with a top-gate structure on plastic substrates using a low temperature printing process will be presented and the device structure and manufacturing processes will be discussed. The polymer TFT array showed excellent air stability and uniform electrical characteristics over a large area. Finally, a 1.5 inch EPD display with 50 dpi resolution using the polymer TFT array will be demonstrated for e-film device applications.
