Display panel, drive method thereof and display apparatus

A drive method for a display panel, wherein

• the display panel comprises a plurality of scan signal lines, a plurality of data signal lines and a plurality of sub-pixels,
• wherein at least one of the plurality of sub-pixels comprises switch assembly and a display unit, wherein the switch assembly at least comprises a control terminal, an input terminal and an output terminal, wherein the input terminal is connected to the data signal lines, the output terminal is connected to the display unit, and the control terminal or the input terminal is connected to the scan signal lines;
• the display panel further comprises at least one switch control line which is connected to the control terminal of the switch assembly and is configured to control on or off of the input terminal and the output terminal of the switch assembly;
• the drive method comprises:
• acquiring a fixation position of a viewer on the display panel, and determining sub-pixels of a fixation region and sub-pixels of a non-fixation region in the display panel according to the fixation position;
• controlling a refresh rate of the sub-pixels of the fixation region to be greater than a refresh rate of the sub-pixels of the non-fixation region.
