ORGANIC LIGHT-EMITTING DISPLAY AND DRIVING METHOD THEREOF

摘要

PROBLEM TO BE SOLVED: To provide an organic light-emitting display and a driving method thereof which can compensate for a characteristic change of a drive transistor.SOLUTION: An organic light-emitting display comprises: a display panel comprising multiple picture elements each having a drive transistor making a light emitting device emit light with data current corresponding to data voltage; a panel drive unit detecting characteristics of the drive transistor including at least one among a threshold value voltage and a migration rate of the drive transistor included in each picture element during a temporal interval that a user does not exist around the display panel, and after completion of characteristic detection of the drive transistor included in each picture element, compensating for input data depending on the detection result and generating the data voltage; and a sensor unit sensing whether a user exists around the display panel and providing the sensing result to the panel drive unit.
