  • Patent number: 10593415
    Abstract: The shift register unit includes an input circuit, a first reset circuit, an output circuit, a second reset circuit, and a first pull-down control circuit. The input circuit provides a forward scan control signal to a first node according to an input signal. The first reset circuit provides a reverse scan control signal to the first node according to a reset signal. The output circuit provides a clock signal to a signal output terminal according to the voltage of the first node. The second reset circuit provides a first voltage signal to the first node and the signal output terminal according to the voltage of a second node. The first pull-down control circuit controls the voltage of the second node according to the voltage of the first node.

  • Publication number: 20170219192
    Abstract: Disclosed is light-emitting assembly comprising an elastic plate comprising: an elastic base and a plurality of connecting parts protrusively provided on the elastic plate, the plurality of connecting parts being spaced apart from each other; and a flexible light-emitting plate secured on a side of the connecting parts facing away from the elastic base, wherein portions of the flexible light-emitting plate located between adjacent connecting parts are arched toward a direction away from the elastic plate to form an arched portion when the elastic plate is in an un-deformed state, and the arched portions of the flexible light-emitting plate are flattened when the elastic plate is deformed by stretching. A method for manufacturing a light-emitting assembly is also disclosed. The light-emitting assembly is applicable to occasions in which the elastic deformation of the light-emitting assembly is required.
