  • Publication number: 20160049126
    Abstract: The present disclosure provides a shift register unit, a gate electrode drive circuit and a display apparatus, which relates to a technical field of display. The shift register unit includes an input reset module, a pull up module, a control module and a pull down module. By inputting a high level into the second signal input end of the input reset module in the touch scan to maintain the level at the pull up control node, the electrical leak effects at the pull up control node may be avoided efficiently. In this way, the defects of insufficient charging rate of the row pixels may be avoided and the dark lines or bad bright lines may be suppressed.

  • Publication number: 20140111471
    Abstract: The present invention discloses a capacitive in-cell touch-screen panel, a touch-positioning method thereof, and a display device. At least one of the gate lines in a TFT array substrate is elected as a touch scanning line, and at least one of the data lines is elected as a touch sensing line; or contrarily, at least one of the data lines is elected as a touch scanning line, and at least one of the gate lines is elected as a touch sensing line, and in this way the function of the touch-screen panel is achieved. Because the gate lines and data lines in a TFT array substrate are used as touch scanning lines and touch sensing lines, there is no need to add additional wirings, and thus the aperture ratio of the TFT array substrate will not be reduced.
