Abstract: The present application discloses a method for reducing brightness of images at least partially. The method includes determining a grayscale mapping table corresponding to a previous frame of image and adjusting grayscale value of each pixel of a current frame of image based on the grayscale mapping table to enhance a contrast ratio to determine an after-adjust grayscale value of each pixel of the current frame of image. Furthermore, the method includes determining one or more coefficients of grayscale reduction based on the after-adjust grayscale value of each pixel of the current frame of image. Moreover, the method includes reducing grayscale value of each pixel of a next frame of image based on the one or more coefficients of grayscale reduction and after-adjust grayscale values of corresponding pixels of the next frame of image.

Abstract: The present disclosure provides a method for controlling a display device, a control apparatus for a display device, and a display device comprising the control apparatus. The method for controlling a display device may comprise the steps of: determining whether or not to perform peak driving for respective backlight sub-regions of the display device, the backlight sub-regions corresponding to sub-display areas of the display device; and performing, in response to a result of the above determining step, data signal compensation at least for sub-display areas whose average luminance values are lower than a preset first luminance threshold among the sub-display areas to which the backlight sub-regions that are determined to be subjected to peak driving correspond.
