Abstract:
1. A method of manufacturing an active matrix organic light-emitting diode (AMOLED), the method comprising: providing a substrate; forming at least a data line and at least a drain metal on the substrate; forming a buffer insulator layer on the substrate, the data line and the drain metal; forming at least an active layer on the buffer insulator layer; forming a gate insulator layer on the active layer and the buffer insulator layer; forming a gate metal on the gate insulator layer above the active layer; using the gate metal as a self-alignment mask and doping an ion on the active layer to form a source and a drain on the corresponding sides of the gate metal; forming a plurality of via holes on the gate insulator layer that reach the data line, the drain metal, the drain and the source surface; forming a plurality of transparent electrodes on each via hole and the gate insulator layer surface, each transparent electrode electrically contacting with the data line, the drain, and the drain metal; forming a pixel define layer on the transparent electrode, the gate metal, and the gate insulator layer to expose the transparent electrode; and forming a light-emitting diode on the transparent electrode.
