Abstract:
A pixel structure of a full-color organic light-emitting diode display device, said pixel structure comprising:a black matrix region deposited and defined on a top surface of an insulating substrate; a buffer layer deposited over said black matrix region; a polycrystalline silicon layer deposited over said buffer layer, said polycrystalline silicon layer having source and drain regions of a first thin-film-transistor and source and drain regions of a second thin-film-transistor defined therein for forming a polycrystalline silicon island; a gate layer deposited over said polycrystalline silicon island and defining gate electrodes of said first and second thin film transistors therein; a storage capacitor; an interlayer deposited over said gate layer and said polycrystalline silicon island and defining source and drain electrode metal regions therein; a passivation layer deposited over said interlayer; a color changing medium region defined in said passivation layer; a layer of transparent conductive material deposited over said color changing medium region and a portion of said passivation layer; an organic light-emitting diode layer deposited over said layer of transparent conductive material and said passivation layer; and a cathode metal layer deposited over said organic light-emitting diode layer.
