The invention relates to an image display processing method and image display processing apparatus of a display apparatus, a display apparatus and a storage medium. The image display processing methodof the display apparatus includes a backlight unit, wherein the backlight unit includes a plurality of backlight subareas, and is driven in a local light modulation mode. The image display processingmethod of the display apparatus includes the steps: based on the backlight power consumption balance of the sth frame of image and the maximal backlight value of each backlight subarea of the (s-1)thframe of image, acquiring the peak value driving threshold of the sth frame of image; acquiring the initial backlight value of each backlight subarea of the sth frame of image, and based on the peakvalue driving threshold, performing peak value driving adjusting on the initial backlight value of each backlight subarea of the sth frame of image, so as to obtain the adjusted backlight value of each backlight subarea of the sth frame of image; and using the adjusted backlight value of each backlight subarea of the sth frame of image to display the Sth frame of image. The image display processing method of the display apparatus can realize synchronous transmission of the backlight data and the peak value driving data, can improve the contrast of the displayed image, and can give a better visual sense to a user.
