摘要： An organic light emitting diode (OLED) pixel circuit includes a driving node, a pixel driving unit, an electroluminescent device, and a compensation unit. The pixel driving unit is coupled to a data line receiving a data voltage and provides a driving voltage to the driving node. The display electroluminescent device is coupled to the driving node for illuminating in response to the driving voltage, wherein the level of the driving voltage is related to an aging factor voltage, corresponding to a usage time of the display electroluminescent device. The compensation unit, including a compensation electroluminescent device, is couple to the driving node and drives the compensation electroluminescent device to illuminate in response to the driving voltage, so as to compensate the aging decay of the display electroluminescent device with the electroluminescent compensation unit.
