摘要： The embodiments of the present application disclose a method of controlling display of a display device, an apparatus thereof and a display apparatus. The display device includes a backlight unit and a display panel, wherein the backlight unit includes a plurality of backlight partitions, each of which is independently driven, and the display panel includes a plurality of display partitions in one-to-one correspondence with the backlight partitions. The method comprises: causing the display panel to display a test image, wherein each pixel of the test image has a same gray value; acquiring a luminance of each display partition of the display panel; determining a compensation coefficient according to the luminance of each display partition; adjusting backlight data of the backlight partition according to the compensation coefficient to obtain adjusted backlight data of each backlight partition; and providing the adjusted backlight data to the backlight unit for display by the display panel.
