摘要:
There is provided an active matrix organic light emitting diode (AMOLED) display including a driver generating analog driving signals based on previously prepared driving data; a pixel unit including an organic light emitting diode connected between first and second power supply terminals receiving first and second power, respectively, charging values equivalent to the driving data according to the driving signals and simultaneously detecting the driving signals in order to detect deterioration in a preset tracking period, allowing current to flow through the organic light emitting diode according to the values charged in the tracking period in a preset holding period, and setting a reset period between the holding period and a tracking period subsequent thereto to reset the charged values; and an ADC detecting a deterioration voltage corresponding to the driving signals having deterioration information of the organic light emitting diode of the pixel unit in the tracking period.
