An organic light emitting display includes a display panel including data lines, gate lines crossing the data lines, and pixels and a panel driving circuit which supplies a data voltage to the pixels of the display panel during a power-on period and then is additionally driven for a predetermined power-on delay duration time delayed from a power-off start time of a power input signal. The panel driving circuit supplies a reverse polarity recovery voltage having a polarity opposite the data voltage to the pixels or supplies a recovery voltage, which is different from a gate voltage of a driving element of each of the pixels, to a source terminal of the driving element of each pixel for the predetermined power-on delay duration time.

Organic light emitting display

An organic light emitting display and a method of erasing an image sticking thereof are provided. In the image sticking erasing method, a panel driving circuit is driven by a logic power voltage during a power-off delay time to discharge pixels.
