Patents by Inventor Hoo Hyeon LEE

Hoo Hyeon LEE 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).

  • Display device and driving method thereof
    Patent number: 11189218
    Abstract: A display device and a driving method thereof are disclosed. The display device includes a display panel including a plurality of pixels connected to data lines; a data driver connected to the data lines and configured to determine first data voltages corresponding to the pixels, to generate second data voltages by adding a compensation voltage to the first data voltages, and to supply the second data voltages to the pixels through the data lines; and a crosstalk compensator connected to the data driver and configured to calculate the compensation voltage by comparing the first data voltages corresponding to pixels disposed in at least three adjacent horizontal lines.
    Type: Grant
    Filed: September 15, 2020
    Date of Patent: November 30, 2021
    Assignee: SAMSUNG DISPLAY CO., LTD.
    Inventors: Mitsuru Fujii, Ji Ye Moon, Ju Gon Seok, Hoo Hyeon Lee
