摘要： A driving method for preventing image sticking of a display panel (805) upon shutdown, and a display device (800). The method includes: receiving a shutdown signal (S01, S16); and adjusting driving signals of a sub-pixel circuit (708, 810) of the display panel (805), so as to reduce the voltage difference between a gate electrode and a source electrode of a driving transistor (T1) of the sub-pixel circuit, and hence allowing the display panel (805) to enter an image sticking prevention mode (S02, S17). The method can prevent image sticking of the display panel (805) at the time of shutdown and hence improve the display quality.

摘要： A pixel circuit is provided which includes a data writing module, a drive module, a control module and an electrochromic device. The data writing module provides a data signal to the control terminal of the drive module under the control of a first control signal. The drive module drives the electrochromic device for colour development or colour fading according to a power supply voltage signal under the control of the data signal. The control module controls the conduction between the drive module and the electrochromic device on the basis of a second control signal, and the control module controls the conduction so that the conduction is realized later than the change in the power supply voltage signal. The pixel circuit effectively removes interference of the power supply voltage signal, avoids display fluctuations caused by the change in the power supply voltage signal, and further improves the display effect.

摘要： 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.
