  • Publication number: 20180357970
    Abstract: A liquid crystal display device may include gate lines, data lines intersecting the gate lines, and pixels electrically connected to the gate lines and the data lines and arranged in pixel columns and pixel rows. The data lines include first-type data lines and second-type data lines. Exactly one pixel column is positioned between every immediately neighboring two of the first-type data lines. No pixel column is positioned between any immediately neighboring two of the second-type data lines. Each of the first-type data lines is electrically connected to a pixel of a first immediately adjacent pixel column in every odd-numbered pixel row and is connected to a pixel of a second immediately adjacent pixel column in every even-numbered pixel row. Each of the second-type data lines is electrically connected to a pixel of exactly one immediately adjacent pixel column in every other pixel row.

  • Publication number: 20170025058
    Abstract: An image display system includes a camera part and an image display part. The image display part includes a user analyzer, a gamma corrector, a gamma voltage generator, and a display panel. The camera part takes a picture of a user and generates a user image signal. The user analyzer calculates the user's viewing direction based on the user image signal. The gamma corrector generates a correction gamma value based on the viewing direction. The gamma voltage generator generates a gamma voltage based on the correction gamma value, and the display panel displays an image corresponding to the gamma voltage. Accordingly, the image display system provides the image having an optimized gamma curve to the user in real time even without a separate input from the user.
