Patents by Inventor HAIYAN KANG

HAIYAN KANG 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: 11092858
    Abstract: The invention discloses a pixel structure and a pixel unit. The pixel structure includes a main electrode; and a plurality of branch electrodes connected to the main electrode; wherein the branch electrode includes a first branch electrode and a second branch electrode, an acute intersecting angle between the first branch electrode and the main electrode is a first angle, and an acute intersecting angle between the second branch electrode and the main electrode is a second angle. The invention solves the whitening phenomenon which occurs in the side view by designing the acute intersecting angle between the branch electrode and the main electrode as the first angle and the second angle.

  • Publication number: 20210217373
    Abstract: A method for driving a pixel matrix is provided, and the pixel matrix includes multiple sub-pixels arranged in a matrix. Voltages applied along any one of data lines change in polarity once every four sub-pixels or every two sub-pixels, any one of the data lines controls voltage inputs of sub-pixel respectively connected to two sides thereof or controls voltage inputs of two sub-pixels both connected to one side thereof. The method includes: receiving an image data and acquiring original pixel data according to the image data; generating a first driving voltage and a second driving voltage according to the original pixel data; and loading the first driving voltage or the second driving voltage to the pixel matrix along any one of the data lines. The invention also provides a display device corresponding to the method. The invention can avoid crosstalk, bright dark lines and improve display effect.
