    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.

    Abstract: A method for detecting a display panel is disclosed. The display panel comprises an array substrate for driving an electroluminescent device. The array substrate comprises pixel electrodes arranged in an array and an array of pixel switches for driving the pixel electrodes. The method comprises the steps of: S1, applying a first driving signal to a manufactured array substrate, monitoring a first voltage on the pixel electrode; S2, forming a second electrode on each of the pixel electrodes of the array substrate; S3, applying a second driving signal to the array substrate formed with the second electrode, monitoring a second current flowing through the second electrode. The pixel electrode is one of the cathode and the anode of the electroluminescent device, the second electrode is the other one of the cathode and the anode of the electroluminescent device.
