ORGANIC LIGHT EMITTING DISPLAY DEVICE

摘要

The embodiment of the present invention relates to an organic light emitting display device. According to the embodiment of the present invention, the organic light emitting display device includes an auxiliary line which is extended in a direction intersecting with data lines and auxiliary data lines, and is connected to a repaired pixel among the display pixels and an auxiliary pixel; and a data driving part which supplies data voltages to the data lines according to gray scale values corresponding to the display pixels and supplies a correction data voltage to the auxiliary data line according to the gray scale value of the repaired pixel. At this time, the data driving part calculates a coupling voltage between the auxiliary line and the display pixels according to the gray scale values corresponding to the display pixels, and determines the correction data voltage according to a coupling voltage. So, an error in luminescence of the organic light emitting diode of the repaired pixel can be prevented.
