Abstract
An organic light emitting diode (OLED) display includes a display panel including data lines, scan lines crossing the data lines, and light emitting cells, which are arranged in a matrix form and each include an OLED, and a panel driving circuit, which reduces a reference voltage applied to an anode of the OLED to a ground level voltage in a sleep-out mode and adjusts the reference voltage at a voltage level greater than the ground level voltage. The reference voltage is held at a voltage level greater than the ground level voltage in a normal driving mode.
