Abstract:
1. A method of manufacturing an active matrix OLED display wherein at least two thin-film transistors and one storage capacitor are provided to drive each pixel of the display, the method comprising the steps of depositing a drain-source and column material on to a substrate followed by photolithographic patterning of drain-source regions and column lines; selectively depositing a doped semiconductor material and full-area depositing of an intrinsic semiconductor material and of a dielectric, by vacuum processes; photolithographically patterning through-interconnections; applying and photolithographically patterning a gate and row material; applying an OLED material and a top electrode material for the OLED; and electrically connecting the thin-film transistors of a pixel circuit and the drain/source region of a driver transistor to the OLED material via the through-interconnections.
