Mapping relation generation method, voltage control method of display device and related equipment

The invention provides a mapping relation generation method, a voltage control method of a display device and related equipment. The method comprises the following steps: determining a first refresh rate parameter and a first display area parameter of a display picture in the display device; adjusting the driving voltage of the display device according to a preset voltage gradient, and determining a first target display parameter difference value of one or more display parameter difference values of the display device under adjacent pairwise driving voltages meeting a preset display parameter condition; determining a first target driving voltage under the first refresh rate parameter and the first display area parameter according to the first target display parameter difference value; and generating a mapping relationship among the first refresh rate parameter, the first display area parameter and the first target driving voltage. Therefore, the determined first target driving voltage is more accurate, and th
