The goal of this thesis is to achieve flexible full color AMOLED displays on clear plastic substrates using high temperature amorphous-silicon TFT’s. Dry dye-printing and solvent-enhanced dye diffusion were used to fabricate side-by-side red, green and blue organic light emitting device (OLED) pixels. The technique was then used to make combined polymer/small molecule devices, in which the prin...
