Abstract:
A pixel structure for an active matrix OLED, comprising:a first switching device having a control terminal coupled to a first scan line and a first terminal coupled to a data line; a first P-type transistor having a drain terminal and a gate terminal coupled to each other and a source terminal coupled to a voltage source, wherein the drain terminal of the first P-type transistor is coupled to a second terminal of the first switch transistor; a second switching device having a first terminal coupled to the gate terminal of the first P-type transistor and a control terminal coupled to a second scan line; a second P-type transistor having a source terminal coupled to the voltage source and a gate terminal coupled to a second terminal of the second switch transistor; a storage capacitor coupled between the voltage source and the gate terminal of the second P-type transistor; and an OLED having an anode coupled to a drain terminal of the second P-type transistor, and a cathode coupled to ground.
