Xinjiang ZHAO 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: 11749189
    Abstract: A charge sharing circuit, a charge sharing method, a display driving module and a display device are provided. The charge sharing circuit includes a control unit and a switch unit. The control unit is electrically connected to first output control ends of two clock signal generation units, and configured to provide, when a first output module controls to not output a first voltage signal under the control of a first output control signal, an on control signal to the switch unit through a control signal output end. The switch unit is configured to control clock signal output ends of the two clock signal generation units to be electrically connected to each other under the control of the on control signal.

  • Patent number: 11621550
    Abstract: The present disclosure provides an overcurrent protection circuit, an overcurrent protection method, a clock signal generation circuit and a display device. The overcurrent protection circuit includes N first overcurrent detection circuits, N second overcurrent detection circuits, a first signal generation circuit, a second signal generation circuit, a first level switching circuit, a second level switching circuit and a control circuit. The first signal generation circuit is configured to output a first control signal to the first level switching circuit upon the receipt of a first overcurrent indication signal. The second signal generation circuit is configured to output a second control signal to the second level switching circuit upon the receipt of a second overcurrent indication signal.
