    Abstract: A surface texture identification display device and a surface texture identification method are provided. The surface texture identification method has a first surface for being contacted with a textured surface. The surface texture identification display device includes: an opaque backplane; a plurality of electroluminescent pixel units, located between the opaque backplane and the first surface and arranged in a plurality of rows extending in a first direction and a plurality of columns extending in a second direction; an image sensor located on a side of the opaque backplane away from the first surface; and a plurality of imaging pinholes, passing through the opaque backplane and configured to image the textured surface onto the image sensor. In a plan view of the surface texture identification display device, the plurality of pixel units and the plurality of imaging pinholes are located within an effective display region.

    Abstract: A shift register unit and a drive method thereof, a gate drive circuit, and a display device are disclosed. The shift register unit includes a shift resister circuit which delays a phase of an input signal from an input terminal to output a first output signal from a first output terminal and an inverting circuit which generates an inverting signal having an inverted voltage with respect to the first output signal and output it from a second output terminal. The shift resister circuit includes a first input circuit configured to control a voltage of a first node, a second input circuit configured to control a voltage of a second node, a latch circuit configured to latch the voltage of the first node and that of the second node as being inverted, and a first output circuit configured to selectively output the second clock signal or a first voltage.
