Abstract
A circuit for driving an organic light emitting diode display includes a display panel that displays an image by using organic light emitting diodes disposed at intersection areas of a plurality of gate lines and a plurality of data lines; a threshold voltage detection control unit that supplies a precharge voltage by sequentially turning on transistors for threshold voltage detection, which are connected among the data lines and the organic light emitting diodes on the display panel, in units of horizontal lines, and enables threshold voltages to be detected; and a source driver that detects threshold voltages of all organic light emitting diodes arranged on a corresponding horizontal line, and repeats an operation, as necessary, for sampling/holding the detected threshold voltages through M sample/hold circuits, converting the sampled/held threshold voltages into digital signals, and storing the digital signals in a memory.
