Mengde CHENG 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).

  • Array substrate combining plane electric field and fringe electric field, driving method thereof and display device
    Patent number: 9966027
    Abstract: The present invention provides an array substrate, a driving method thereof, and a display device. The array substrate comprises a plurality of gate lines and a plurality of data lines, and the plurality of gate lines cross with the plurality of data lines to define a plurality of pixel units. Each of the pixel units comprises a first pixel electrode, a second pixel electrode and a floating electrode which are insulated from each other, and the floating electrode is provided in a layer different from that in which the first pixel electrode and the second pixel electrode are provided. The first pixel electrode and the second pixel electrode are capable of forming a plane electric field therebetween, and the floating electrode and both the first pixel electrode and the second pixel electrode are capable of forming a fringe electric field therebetween.
