A method of forming high definition patterned organic layers in a full-color electroluminescent (EL) display array on a two-dimensional thin film transistor (TFT) array substrate is described. The substrate has subpixels with each subpixel having raised surface portions and one recessed surface portion which reveals a bottom electrode. Red, green, and blue color forming organic EL layers are formed in the designated subpixels in accordance with a selected color pattern. The method uses a donor support which is coated with a transferable coating of an organic EL material. The donor support is heated to cause the transfer of the organic EL material onto the designated recessed surface portions of the substrate forming the colored EL medium in the designated subpixels. Optical masks and, alternatively, an aperture mask are used to selectively vapor deposit respective red, green, and blue organic EL media into the designated color EL subpixels. <IMAGE> |
