ORGANIC LIGHT EMITTING DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

The present invention relates to an organic electroluminescent display device to improve display quality. According to an embodiment of the present invention, the organic electroluminescent display device comprises: pixels including a driving transistor to control a current amount supplied to an organic light emitting diode; and a compensation unit connected with the pixels via data lines, and including one or more sensing units to extract threshold voltage information of the driving transistor from the pixels, wherein the sensing units receive noise current from a plurality of data lines, offset the supplied noise current, and extract threshold voltage information of the driving transistor.
