Abstract
A luminance compensating method of a display device, a luminance compensating device, a display device and a storage medium. The display device includes a backlight module and a display panel, the display panel includes a plurality of portions, the backlight module includes a plurality of backlight units, and the plurality of backlight units respectively correspond to the plurality of portions. The method includes: setting luminance values of the plurality of backlight units of the backlight module to an identical set luminance value, and setting gray level data of a plurality of pixel units of the display panel to an identical set gray level value; measuring light-emitting luminance values of the plurality of portions of the display panel to obtain a first luminance matrix of the display panel, in a case where the plurality of backlight units emit light; determining a compensation-coefficient matrix based on the first luminance matrix.
