Pixel circuit, method of driving a pixel circuit, and organic light emitting display device
Abstract:
A pixel circuit includes an organic light emitting diode, a first PMOS transistor coupled between a first power voltage and an anode electrode of the organic light emitting diode, a second PMOS transistor coupled between a first node and the anode electrode of the organic light emitting diode, a first capacitor coupled between a second node and the first node, a second capacitor coupled between the first power voltage and the second node, a third PMOS transistor coupled between a data line and the second node, a fourth PMOS transistor coupled between a third node and the second node, a third capacitor coupled between the third node and a gate terminal of the third PMOS transistor, and a fifth PMOS transistor coupled between the data line and the third node.
