Image display processing method and device, display device and non-volatile storage medium

An image display processing method for a display device, wherein the display device comprises a backlight unit, the backlight unit comprises a plurality of backlight blocks and is configured to be driven by a local dimming mode, and the image display processing method comprises:

• obtaining a peak driving threshold of an (s-1)-th frame of image based on respective backlight values of the plurality of backlight blocks of the (s-1)-th frame of image after a first local dimming process is performed on the (s-1)-th frame of image;
• acquiring respective initial backlight values of the plurality of backlight blocks of an s-th frame of image, and performing a peak driving process on the respective initial backlight values of the plurality of backlight blocks of the s-th frame of image based on the peak driving threshold of the (s-1)-th frame of image, so as to obtain respective adjusted backlight values of the plurality of backlight blocks of the s-th frame of image;
• and
• displaying the s-th frame of image by using the respective adjusted backlight values of the plurality of backlight blocks of the s-th frame of image, wherein s is an integer greater than 1;
• the method further comprises:
• acquiring a maximum backlight value of the plurality of backlight blocks of the (s-1)-th frame of image;
• judging whether the maximum backlight value of the plurality of backlight blocks of the (s-1)-th frame of image is greater than or equal to a preset threshold;
• and
• judging whether a total backlight power consumption of the (s-1)-th frame of image is less than a conventional backlight power consumption,
• wherein in a case where the maximum backlight values of the respective backlight blocks of the (s-1)-th frame of image is great than or equal to the preset threshold and the total backlight power consumption of the (s-1)-th frame of image is less than the conventional backlight power consumption, obtaining the peak driving threshold of the (s-1)-th frame of image based on the backlight values of the respective backlight blocks of the (s-1)-th frame of image after the first local dimming process is performed on the (s-1)-th frame of image is performed, and otherwise, the peak driving process on the respective initial backlight values of the plurality of backlight blocks of the s-th frame of image is not performed.
