Abstract

An organic light emitting diode display includes a data driving circuit which converts pixel data into a data voltage and supplies the data voltage to data lines during a data enable period, and senses changes in driving characteristics of a display panel within an extended vertical blank period, a scan driving circuit which supplies a scan pulse synchronized with the data voltage to scan lines during the data enable period, and outputs a scan pulse within the extended vertical blank period, and a timing controller which compensates for data of an input image using a compensation value determined based on the changes in the driving characteristics, transmits the compensated data to the data driving circuit, and controls operation timing of the data driving circuit and operation timing of the scan driving circuit.
