Patents by Inventor Dachao LIU

Dachao LIU 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: 11915649
    Abstract: Embodiments of the present disclosure are directed to a pixel circuit and a display panel. The pixel circuit includes a light-emitting device, a driving transistor, a data signal writing module, a threshold voltage compensation module, a first initialization module, a light-emitting control module, and a coupling capacitor. By adding a coupling capacitor in the pixel circuit, the gate potential of the driving transistor is maintained at the initial value under a long period of display.

  • Publication number: 20200105180
    Abstract: A driving method for a display device. The display device includes a display panel configured to display images and a driving chip configured to provide driving signals and data signals to the display panel. The driving method includes inputting initial image data; determining whether picture switching occurs; and in response to determining that picture switching occurs, using a progressive scanning mode to provide the driving signals to the display panel, and in response to determining that picture switching does not occur, using an interlaced scanning mode to provide the driving signals to the display panel.
