摘要： The present disclosure provides a common voltage compensation circuit including a feedback signal input terminal and a compensation sub-circuit. The compensation sub-circuit is configured to generate a compensation voltage for compensating a common voltage according to a feedback signal from the feedback signal input terminal and a reference common voltage. The common voltage compensation circuit also includes a first filter sub-circuit, a first terminal of the first filter sub-circuit is electrically coupled to the feedback signal input terminal, and a second terminal of the first filter sub-circuit is electrically coupled to a first clock signal line. The feedback signal line arranged is adjacent to a second clock signal line, and a first clock signal in the first clock signal line and a second clock signal in the second clock signal line are inverted relative to each other. The present disclosure also provides a display driver and a display device.

摘要： An array substrate, a display panel, a display device, an operating method, and a manufacturing method are disclosed. The array substrate includes a wiring structure formed on a base substrate, and the wiring structure includes a common electrode line for connecting a common electrode, and a plurality of signal lines. The plurality of signal lines include at least one pair of signal lines, and the pair of signal lines include a first signal line and a second signal line. The first signal line is disposed on a first side of the common electrode line and is configured to transmit a driving signal for a gate driving circuit. The second signal line is disposed on a second side of the common electrode line and is configured to transmit an inverted signal of the driving signal.
