Abstract: The present application discloses a luminance compensation method of a display panel, a luminance compensation apparatus, a luminance compensation device and a storage medium. The method includes: acquiring first correspondence relationships respectively corresponding to touch sensing regions, wherein the first correspondence relationship is a correspondence relationship of light-emitting luminance and mutual capacitances; acquiring first mutual capacitances of the touch sensing regions transmitted by a touch chip; determining actual luminance values of light-emitting pixel regions respectively corresponding to the touch sensing regions according to the first mutual capacitances and the first correspondence relationships of the touch sensing regions, wherein the light-emitting pixel region comprises at least one light-emitting pixel; generating a compensation instruction according to the actual luminance values of the light-emitting pixel regions and target luminance values, thereby causing a driving chip to make luminance compensation for the light-emitting pixel regions according to the compensation instruction.
