Summary:The invention relates to an image display control method, device, medium and display screen control system. The method comprises the following steps: acquiring an input gray value of each pixel pointof an input image; for each pixel point, if an input gray value of the pixel point is greater than a preset gray threshold, determining a PWM value corresponding to the pixel point according to the input gray value and the preset gamma value; or if the input gray value of the pixel point is less than or equal to the preset gray threshold, determining the PWM value corresponding to the pixel pointaccording to the input gray value; and performing pulse width modulation according to the PWM value of each pixel point so as to display the input image on a target display screen. Therefore, when theimage is displayed on the display screen, the image on the display screen is continuous and uniform and the display effect can be improved. The display quality of the output image can be guaranteed when the method is applied t
