Abstract: A driving method for preventing image sticking of a display panel upon shutdown, and a display device. The method includes: receiving a shutdown signal; and adjusting driving signals of a sub-pixel circuit of the display panel, so as to reduce the voltage difference between a gate electrode and a source electrode of a driving transistor of the sub-pixel circuit, and hence allowing the display panel to enter an image sticking prevention mode. The method can prevent image sticking of the display panel at the time of shutdown and hence improve the display quality.

Abstract: A pixel compensation method, pixel compensation apparatus and display device are provided. In the blanking section of (2n−1)th display frame, the detection line corresponding to the first sub-pixel column of the same color sub-pixels in the nth row is charged with an additional detection voltage, such that the detected voltage on this detection line is the sum of the detection voltage and a coupling voltage. The detection line corresponding to the second sub-pixel column of the same color sub-pixels is not charged with the additional detection voltage, such that the detected voltage on this detection line is the coupling voltage. The detection voltage corresponding to the first sub-pixel column is obtained according to the voltage on the detection line corresponding to each of the same color sub-pixels. Similarly, in the blanking section of (2n)th display frame, the detection voltage corresponding to the second sub-pixel column may be obtained.
