Abstract: The present disclosure provides an OLED array substrate, and a display panel and a display device including the OLED array substrate. A VDD grid is provided in an existing AMOLED array substrate with a compensation function, VDD lines are connected with the VDD grid via switches, which are applied with corresponding voltages to be switched on during a light emitting stage, such that the VDD lines are electrically connected in parallel to the VDD grid, thus a total resistance of the VDD lines and the VDD grid connected in parallel is decreased relative to the own resistance of the VDD line, so as to reduce the voltage drop on the VDD line in a direction in which the scanning control lines extend, and in turn to decrease a variation in a OLED driving voltage signal effectively, ensuring uniformity of luminance across the display area.
