Patents by Inventor Zelin Yang

Zelin Yang has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 12333990
    Abstract: Gate driving circuits, display panels, and display devices are provided. The gate driving circuit includes cascaded gate driving units, each of which includes an input unit, an output unit, a reset control unit, and a pull-down holding unit. The input unit outputs a driving signal to a first node. The output unit outputs a scanning signal in response to the driving signal. The reset control unit outputs a reset control signal to a second node during a first period. The pull-down holding unit receives the reset control signal. The pull-down holding unit outputs a first voltage signal to the first node in response to the reset control signal to reset a potential of the first node during the first period, and outputs the first voltage signal to the first node to maintain the potential of the first node during a second period.

  • Patent number: 12175917
    Abstract: A gate drive circuit and a display panel. The gate drive circuit includes multi-stage cascaded gate drive units. The gate drive units each include a pull-up control module, an output module, a pull-down module, a pull-down maintain module, a first reference low-level signal input terminal, a second reference low-level signal input terminal, and a pull-up node located in a line between the pull-up control module and the output module. The pull-up control module includes a pull-up control transistor that is electrically connected to the pull-up node and configured to pull a potential of the pull-up node up. The output module includes a scan signal output transistor that is electrically connected to the pull-up node and configured to output a present-stage scan signal under control of the potential of the pull-up node.
