  • Patent number: 11508328
    Abstract: Provided is a display device having the following structure and driving method thereof. The display device comprises a circular display panel including an active area on which an image is displayed and a non-active area on which no image is displayed, a gate driving circuit disposed in the non-active area to drive a plurality of gate lines, a first data driving circuit disposed in the non-active area to drive first-group data lines in the circular display panel, and a second data driving circuit disposed in the non-active area, in a position opposite to the first data driving circuit with respect to the active area, to drive second-group data lines in the circular display panel. The frequency of a data clock is reduced using a plurality of data driving circuits in a pad area. The bezel size of a circular display panel is reduced.

  • Patent number: 11494015
    Abstract: A display panel and a manufacturing method thereof are proposed. A display panel may include: a touch electrode provided to supply a common voltage through an electrode; a first signal line connected to the touch electrode and provided to supply the common voltage applied by a driving IC to the touch electrode; a plurality of dummy lines provided to be connected to the touch electrode; and a switching transistor provided to supply the common voltage to a second signal line by being switched by an applied VCOM enable signal, wherein the second signal line is configured to supply the common voltage to the touch electrode.
