A printed circuit board, a method for determining an engagement state between the printed circuit board and a flexible printed circuit, and a display device are provided. The printed circuit board includes a substrate, a connector fixed on the substrate, and configured to be connected with the flexible printed circuit, and a determining circuit connected with the connector. The secondary pin is added to the connector, and can determine together with the determining circuit, added to the substrate, connected with the secondary pin, an engagement state between the first pins of the connector, and the second pins of the flexible printed circuit.

Printed circuit board, method for determining engagement state between printed circuit board and flexible printed circuit and display device

A common voltage compensation unit and compensation method, a driving circuit and a display panel are disclosed. In the common voltage compensation unit provided by the disclosure, the first compensation module may be used for outputting a first common voltage to the common electrode line in the pixel charging period of time, and the second compensation module may be used for outputting a second common voltage to the common electrode line in the pixel non-charging period of time.

Common voltage compensation unit and compensation method, driving circuit and display panel

An array substrate, a driving method thereof and a display device are provided. The array substrate includes a base substrate, a pixel electrode located on the base substrate; a first gate line and a second gate line located on the base substrate at both sides of the pixel electrode, respectively, the pixel electrode being partially overlapped with the first gate line and the second gate line respectively to form a first storage capacitor and a second storage capacitor respectively; and a gate driver connected with the first gate line and the second gate line and configured to sequentially provide a gate signal to the first gate line and the second gate line and perform a waveform chamfering operation to the gate signal.
