Patents Assigned to Chipone Microelectronics Technology (Hefei) Co.
  • Patent number: 10410570
    Abstract: The present disclosure relates to the technical field of LED display screens, and in particular, to an LED display device and a method for driving the same. The driving method includes: generating a grayscale data in accordance with an image to be displayed; generating a control signal in accordance with the grayscale data, wherein the control signal includes a plurality of subframe signals each having a duration corresponding to a respective subframe display time; and controlling the corresponding LED lamps to be turned on or off by use of the subframe signals in each subframe of the frame cycle. The frame cycle includes reset time periods separating the successive subframes from each other. The order of the plurality of subframes in the frame cycle can be adjusted by use of the grayscale data.
