    Abstract: The present disclosure provides a thickness measuring method and device. The thickness measuring method is used for measuring a thickness of a layer to be measured of a light-transmitting sample to be measured and comprising the steps of: placing the sample to be measured between an optical device and a metal layer, the optical device comprising a light incident surface and a light exit surface; adjusting incident light emitted to the light incident surface of the optical device so that an intensity of light exiting the light exit surface of the optical device is less than 10−12 W/m2, so as to obtain optical parameters of the incident light; and calculating a thickness of the layer to be measured according to the optical parameters of the incident light.

    Abstract: A method for fabricating an array substrate, an array substrate, and a display device are disclosed. The method includes forming a whole layer of opaque film on a substrate; treating the film to form a transparent region and an opaque region in the film, wherein the opaque region corresponds with a channel region of an active layer; and forming a thin film transistor on the film which has been treated. In the method, prior to forming the thin film transistor, the whole layer of opaque film is formed to comprise the transparent region and the opaque region. When other films are deposited on the whole layer of film, no difference in height occurs, and this further avoids various defects due to difference in height.

    Abstract: There are disclosed a display substrate and a display device. The display substrate comprises a common electrode line, a plurality of pixel units with each comprising a pixel electrode and a plurality of first switch units disposed respectively between the common electrode line and the pixel electrodes. Each of the first switch unit is configured to be turned on within a pre-set time period after the display substrate is powered off to connect the pixel electrode to the common electrode line and be turned off when the display substrate is powered on to disconnect the pixel electrode from the common electrode line. In this way, after the power-off, the charges stored in the pixel electrode are neutralized in the common electrode line. Thus, the pixel electrode and the common electrode can be discharged by the same discharge circuit, which guarantees no DC residue in the discharged pixel electrode.
