Driving method and drive circuit of display panel, display panel, and display device

A drive circuit of a display panel, comprising:

• a receiving circuit configured to receive initial image data of a frame, wherein a resolution of an initial image corresponding to the initial image data is different from a resolution of the display panel, and the initial image data comprises a plurality of pieces of initial gray scale data for displaying the initial image;
• a target determining circuit configured to determine target gray scale data corresponding to panel sub-pixels in the display panel according to the initial gray scale data in the initial image data, the resolution of the initial image and the resolution of the display panel;
• and
• a display drive circuit configured to drive the display panel to display according to the target gray scale data.

A display panel, comprising:

• a plurality of panel sub-pixels, a plurality of scanning lines, a plurality of data lines, a plurality of switch control circuits and a plurality of switch control lines, wherein a row of panel sub-pixels corresponds to at least one scanning line among the plurality of scanning lines, and a column of panel sub-pixels corresponds to at least one data line among the plurality of data lines;
• each panel sub-pixel comprises a storage electrode;
• in each panel sub-pixel group, every two adjacent panel sub-pixels are coupled through a switch control circuit;
• the switch control circuit is further coupled with the scanning line corresponding to the panel sub-pixel and at least one switch control line among the plurality of switch control lines;
• and the switch control circuit is configured to conduct and disconnect the storage electrodes in the coupled panel sub-pixels in response to signals on the coupled scanning lines and signals on the switch control lines.
