description The invention discloses a brightness compensation method and device of a display panel and display equipment. The brightness compensation method of the display panel comprises the following steps: determining compensation data corresponding to a sub-pixel according to a pre-display gray scale corresponding to the sub-pixel; wherein when the pre-display gray scale is greater than or equal to a set gray scale threshold value, the compensation data comprises first compensation data and second compensation data; when the pre-display gray scale is smaller than a set gray scale threshold value, the compensation data comprises second compensation data; wherein the first compensation data is used for voltage drop compensation, and the second compensation data is used for mura compensation; and providing a corresponding driving signal for the sub-pixel according to the pre-display gray scale and the corresponding compensation data. According to the technical scheme, the brightness compensation effect of the display pa
