Abstract

An organic light-emitting diode (OLED) display is disclosed. In one aspect, the display includes a driving transistor having a gate electrode electrically connected to a first node and configured to supply a driving current to an OLED based on a voltage of the gate electrode. A storage capacitor electrically connects to the first node and is configured to maintain a constant voltage at the first node. A switching transistor electrically connects to the first node and includes a pair of transistors that are configured to be simultaneously turned on based on a first control signal. The transistors are serially connected to each other via a second node, and a current path circuit electrically connects to the second node and is configured to receive a charge stored in a capacitance of the second node when the switching transistor is turned off.
