Pixel driving circuit and driving method therefor, and display panel

A driving method of a display device and a display device are disclosed, the driving method including: detecting current pixel inversion mode; determining pixel polarities and first data signals for a next frame based on pixel polarities of a current frame and the inversion mode; determining whether the next frame is an overload image based on pixel bright-or-dark values and grayscale values corresponding to the next frame and those corresponding to the overload image; when the next frame is an overload image, modifying a pixel polarity order corresponding to the first data signals, and generating and outputting second data signals to drive the display device to display the next frame; otherwise outputting the first data signals to drive the display device to display the next frame. The pixel polarities corresponding to the first data signals are in a different order than those corresponding to the second data signals.

Driving method of display device, and display device

Disclosed are a public voltage compensation method and a display panel. The public voltage compensation method includes: installing the first multi-channel operational amplifier; connecting the first public voltage feedback output terminal with the first feedback input terminal, connecting the second public voltage feedback output terminal with the second feedback input terminal, connecting the first compensation input terminal with the first compensation output terminal, connecting the third compensation input terminal with the third compensation output terminal, connecting one of the n second compensation input terminals with the second compensation output terminal, and connecting one of the n fourth compensation input terminals with the fourth compensation output terminal; interconnecting each of the n second compensation input terminals and interconnecting each of the n fourth compensation input terminals.
