Patents by Inventor Wangjing BAI

Wangjing BAI 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: 10741137
    Abstract: A display driving device is provided, which includes a detecting circuit, a comparing circuit coupled to the detecting circuit, and a timing control circuit coupled to the comparing circuit. The detecting circuit detects, and sends to the comparing circuit, a common voltage from each of a plurality of regions in the display panel. The comparing circuit compares the common voltage with a reference voltage and determines whether it is normal. Based on the determination result from the comparing circuit, the timing control circuit adjusts a data voltage of a region having an abnormal common voltage so as to allow a positive data voltage and a negative data voltage of the region to be symmetrical to the common voltage of the region. A display driving method based on the display driving device and a display apparatus having the display driving device are also disclosed.

  • Patent number: 10490149
    Abstract: The present disclosure relates to a discharging circuit and a driving method thereof, and a display device. The discharging circuit of the present disclosure includes a control circuit, a time delay circuit, a first discharging circuit and a second discharging circuit. The control circuit is configured to control potential of a control signal output terminal of the control circuit. The time delay circuit is configured to delay a switched-on time of the second discharging circuit. The first discharging circuit is configured to pull down a potential of a data signal terminal to a potential of a common voltage terminal, under control of a control signal output from the control circuit. The second discharging circuit is configured to release the potential of the common voltage terminal and the potential of the data signal terminal under the control of the time delay circuit.
