ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

Disclosed is an organic light emitting display device which is capable of rapidly sensing a characteristic variation in a pixel including an organic light emitting diode and a driving transistor. The organic light emitting display device may include a display panel including a pixel formed adjacent to each crossing area of gate and data lines, and a sensing line provided in parallel to the data line and connected with the pixel. The device includes a data driver provided with a sensing data generator for sensing a characteristic variation of the pixel through the sensing line and generating sensing data based on the characteristic variation of the pixel for a sensing mode. The sensing data generator generates the sensing data for the pixel by converting current flowing from the pixel to the sensing line into voltage, and converting the voltage to a digital representation using an analog-to-digital conversion method.
