Ukjae JANG 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: 11721292
    Abstract: A display apparatus includes a display panel, a driving controller, and a data driver. The display panel is configured to display an image based on input image data. The driving controller is configured to determine whether the input image data include a display quality deteriorating pattern. The driving controller is configured to determine a first compensation value for compensating a first area disposed at a first side of a main area of the display quality deteriorating pattern and a second compensation value for compensating a second area disposed at a second side of the main area opposite to the first side of the main area, according to a position of the main area. The data driver is configured to apply a data voltage to the display panel using the first compensation value and the second compensation value.

  • Patent number: 10937353
    Abstract: A display apparatus includes a display panel including a plurality of gate lines, a plurality of data lines, and a plurality of subpixels, the subpixels being connected to the gate lines and the data lines, a driving controller configured to analyze input image data and to determine a driving mode from among one of a first driving mode and a second driving mode, a gate driver configured to output gate signals having timings different from one another to the gate lines in the first driving mode and to output gate signals having the same timing to at least two gate lines in the second driving mode, and a data driver configured to output data voltages to the data lines.
