  • Patent number: 9430982
    Abstract: A display apparatus is disclosed. In one aspect, the apparatus includes a display panel including pixels connected to gate lines and data lines, a gate driver driving the gate lines, a data driver driving the data lines, and a control circuit controlling the gate driver and the data driver to display an image on the display panel. The control circuit applies a common voltage to the display panel. The control circuit compares the common voltage applied to the display panel and a feedback common voltage fedback from the display panel and applies a gate-on voltage having a voltage level corresponding to the compared result to the gate driver.
    Type: Grant

  • Patent number: 8411005
    Abstract: A liquid crystal display (LCD) apparatus includes an LCD section and a driving section. The driving section provides the LCD section with a compensated gradation datum based on a first gradation datum of an (n)-th frame, a second gradation datum of an (n+1)-th frame and a third gradation datum of an (n?1)-th frame. The driving section provides the LCD section with a sum total of a pre-tilt value that is varied in accordance with the gradation and the first gradation datum when the gradation of the second gradation datum is higher than that of the first gradation datum. The driving section provides the LCD section with the first gradation datum when a gradation of the second gradation datum is lower than that of the first gradation datum.
