  • Patent number: 9552759
    Abstract: A display apparatus includes a display panel including a driving part arranged along one side of the display panel, the display panel including a plurality of first gate lines that zigzag across the display in a diagonal direction between the first and second directions by alternately extending in the first and the second directions. The display device includes a first display area and a second display area, pixels within the first display area always receiving gate signals from a driving part connected to an end of the first gate lines. Within the second display area, a second gate lines extending in the first direction may be electrically connected to the first gate lines that relay gate signals to the first gate lines. This results in a reduced peripheral area of the display area, so that many displays can be combined together to produce a single image.

  • Patent number: 9472154
    Abstract: A display panel includes a plurality of pixels which is arranged in a pixel column and a pixel row, a gate line which is connected to pixels in a same pixel row, a first data line which is connected to pixels in a same pixel column, and a second data line which is connected to remaining pixels except for the pixels connected to the first data line among the pixels in the same pixel column. Two odd-numbered pixel rows and two even-numbered pixel rows are alternately driven so that a charge period of the pixel may be extended by 2H. In addition, a kickback difference between the odd-numbered pixel row and the even-numbered pixel row may be decreased so that a display quality may be improved.
