Abstract: 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.

Abstract: 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.

Abstract: The present invention provides a wiring structure of high frequency signal wires and a PCB board including the wiring structure of high frequency signal wires. A test part is formed by extending a high frequency signal wire from a connection end connected with a solder pad, and a test window corresponding to a position of the test part is provided on a copper foil which covers the solder pad and the test part, to expose the high frequency signal wire, such that a high frequency signal transmitted via the high frequency signal wire can be directly tested at the test window. Thus, circular test points used in the prior art can be removed, to effectively solve the problem of insufficient space on a PCB; accordingly, lengths of the high frequency signal wires become more precise, so as to ensure a synchronization of transmission of the high frequency signal wires.
