Abstract:
The present disclosure provides an organic light emitting display device capable of sensing changes in characteristics due to a heat of an analogue-to-digital converting portion to convert sensing voltages corresponding to the threshold values into digital values with the threshold voltages when the threshold voltages of the driving transistors of an organic light emitting display panel are sensed in each horizontal line unit.
