US 11,145,265 B2 · Display device and driving method therefor

Abstract

Embodiments of the present disclosure provide a method for driving a display device to display an image sequence and a display device therefor. The display device includes a backlight module having a plurality of backlight partitions. The image sequence includes at least a first frame image and a second frame image. The method includes determining a first region in the first frame image and a second region in the second frame image that correspond to an overlapping portion of the first frame image and second frame image as overlapping regions; obtaining, based at least partially on a first backlight value of a first backlight partition(s) corresponding to the first region, a second backlight value of a second backlight partition corresponding to the second region; and controlling a backlight brightness of the second backlight partition based on the second backlight value when the display device displays the second frame image.

A method for driving a display device to display an image sequence, the display device comprising a backlight module having a plurality of backlight partitions, the image sequence comprising at least a first frame image and a second frame image, the method comprising:

determining a first region in the first frame image and a second region in the second frame image as overlapping regions, the first region and the second region corresponding to an overlapping portion between the first frame image and second frame image;
obtaining, based at least partially on a first backlight value of one or more first backlight partitions corresponding to the first region, a second backlight value of a second backlight partition corresponding to the second region;
and
controlling a backlight brightness of the second backlight partition based on the second backlight value when the display device displays the second frame image.

A display device for displaying an image sequence, the image sequence comprising at least a first frame image and a second frame image, the display device comprising:

a backlight module having a plurality of backlight partitions;
and
a display controller communicatively connected to the backlight module to control backlight brightnesses of the backlight partitions when the display device displays the image sequence, the display controller being configured to:
determine a first region in the first frame image and a second region in the second frame image as overlapping regions, the first region and the second region corresponding to an overlapping portion between the first frame image and second frame image;
obtain a second backlight value of a second backlight partition corresponding to the second region based at least partially on a first backlight value of one or more first backlight partitions corresponding to the first region;
and control a backlight brightness of the second backlight partition based on the second backlight value when the display device displays the second frame image.
