1. A control method for a display panel, comprising following acts performed by a processor:
converting gray data of a display picture into a gray voltage at a first refresh frequency;
calculating an average gray voltage of the display picture according to the gray voltage of the display picture;
determining a display parameter matched with the display picture according to the average gray voltage of the display picture; and
outputting a control signal of the display picture to the display panel according to the display parameter matched with the display picture, wherein the control signal comprises at least one of: a display data keep signal for keeping a display data keep voltage matched with the display picture, and an anode reset signal of a light emitting element of the display panel,
wherein a display stage of the display picture comprises: a refresh stage and a keep stage;
the display parameter comprises at least one of: the display data keep voltage of the keep stage; and a first anode initial voltage of the refresh stage and a second anode initial voltage of the keep stage,
wherein no control signal of the display picture is outputted to the display panel-when there is no display parameter matched with the display picture.
