DISPLAY PANEL AND ORGANIC LIGHT-EMITTING DIODE DISPLAY INCLUDING THE SAME

摘要

A display panel and an organic light-emitting diode (OLED) display including the display panel are disclosed. The display panel includes a first pixel configured to emit a first color of light, a second pixel configured to emit a second color of light, and a third pixel configured to emit a third color of light. Each of the first to third pixels includes a light emission current applying unit including a driving transistor and a storage capacitor, a gate electrode of the driving transistor configured to receive a data signal from a display driver of the OLED display. The panel includes a light emission unit configured to emit light based on a light emission current. The panel also includes an initialization voltage supply unit configured to provide an initialization voltage to the gate electrode of the driving transistor and the first electrode of the OLED.
