Pixel structure of an organic light-emitting diode display device

A pixel structure of an organic light-emitting diode (OLED) display device, comprising:

• a black matrix region deposited and defined on a surface of an insulating substrate;
• a buffer layer being deposited over said black matrix region and comprising source and drain electrode regions of a first thin-film-transistor, source and drain electrode regions of a second thin-film-transistor, a storage capacitor and a resistor, said resistor being adjacent to said source region of said second thin-film-transistor and electrically connected to said storage capacitor;
• an interlayer being deposited over said buffer layer and comprising a gate layer, said gate layer having a gate region of said first thin-film-transistor and a gate region of said second thin-film-transistor;
• a passivation layer deposited over said interlayer layer;
• and
• an organic electroluminescent element deposited over said passivation layer;
• wherein said resistor has a first end connected in series with the source electrode of said second thin film transistor and a second end connected to a ground or voltage source.
