ORGANIC LIGHT-EMITTING DISPLAY DEVICE AND DRIVING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a reliable organic light-emitting display device which can compensate image sticking on a frame basis in real time to improve image quality.

SOLUTION: An organic light-emitting display device comprises: an organic light-emitting diode; a drive transistor which supplies driving current to the organic light-emitting diode; a data line which transmits a data signal corresponding to the driving transistor; a first switch including a first electrode connected to negative electrode of the organic light-emitting diode and a second electrode connected to the data line; a second switch including a first electrode connected to the data line and a second electrode connected to a gate electrode of the drive transistor. By turning on the first switch, a prescribed primary current is transmitted to the organic light-emitting diode so that the voltage of the negative electrode of the organic light-emitting diode is transmitted by the data line, the transmitted voltage detects the degree of deterioration of the organic light-emitting diode, and the data signal that is transmitted to the data line is compensated for compensating the detected deterioration.
