Pre-charging parameter determination method, image display method and display device

The embodiment of the invention provides a pre-charging parameter determination method, an image display method and a display device, and the method comprises the steps: selecting a binding point gray scale which does not establish a corresponding relation from a plurality of preset binding point gray scales; obtaining a current pre-charging parameter of the currently selected binding point gray scale and a current to-be-displayed image of the currently selected binding point gray scale; pre-charging the first row of pixels of the current to-be-displayed image by using the current pre-charging parameter; acquiring the current display brightness of the first row of pixels and the Nth row of pixels of the current to-be-displayed image; under the condition that the brightness difference between the current display brightness of the first row of pixels and the current display brightness of the Nth row of pixels of the current to-be-displayed image is smaller than a preset difference degree threshold value, the co
