摘要
A pixel circuit for a display device is disclosed. The pixel circuit may include a drive transistor configured to control an amount of current from a first power supply to a light-emitting device depending upon a voltage applied to a gate of the drive transistor. The light-emitting device includes a first terminal electrically connected to a second terminal of the drive transistor and a second terminal electrically connected to a second power supply. The pixel circuit may also include a storage capacitor including a first plate connected to the gate terminal of the drive transistor and a second plate connected to a first node. The pixel circuit may also include a plurality of transistors configured to couple the first power supply, a data voltage input line, and a preset voltage input line to the pixel circuit.
