Driving circuits, compensation circuits and signal compensation method for pixel of active organic electro-luminescence device

摘要

A driving circuit of a pixel of an active organic electro-luminescence device for driving an emitting device in the pixel of the active organic electro-luminescence device is provided. A voltage sensor is adapted for sensing the voltage of the emitting device and sending out the signal according to the voltage. A compensation unit is adapted for receiving the signal output from the voltage sensor. A compensating signal is sent to an emitting device driving unit for compensating the data signal input into the pixel of active organic electro-luminescence device so as to improve uniformity in the brightness of the active organic electro-luminescence device.
