Abstract: A method (200) and an apparatus (500) for compensating for brightness of a display panel (140), and a display device (100) are provided. The method (200) for compensating for brightness of a display panel (140) includes: timing a vertical blanking interval (Vblank) in a current frame on the display panel (140) (202); and determining, in response to that a timing time of the vertical blanking interval (Vblank) reaches a first threshold time, a first value used to perform first compensation on brightness of the display panel (140) during the vertical blanking interval (Vblank) in the current frame (204). According to the method (200) for compensating for brightness of a display panel (140), a brightness change caused by current leakage can be compensated for by adjusting a related analog voltage in a timely manner.
