    Abstract: The display substrate includes a base substrate and a plurality of pixel units disposed on the base substrate. Each of the pixel units is composed of 5 sub-pixels. The 5 sub-pixels include 1 red sub-pixel, 2 green sub-pixels, 1 blue sub-pixel and 1 white sub-pixel. Each of the sub-pixels includes a white light emitting unit. The red sub-pixel, the green sub-pixels and the blue sub-pixel further include color film layers corresponding to respective light emitting colors of the red sub-pixel, the green sub-pixels and the blue sub-pixel. The white sub-pixel is adjacent to the blue sub-pixel, and an aperture area of the blue sub-pixel is smaller than that of the green sub-pixels and smaller than that of the red sub-pixel.

    Abstract: Provided are a shift register unit, a shift register, a display panel and a driving method thereof. The shift register unit includes: an input circuit electrically coupled to an input terminal, a first voltage terminal and a pull-up node; an output circuit electrically coupled to the pull-up node, a first clock terminal, a first scan control terminal, a first output terminal and a second output terminal; and a scan control circuit electrically coupled to the second output terminal, a second voltage terminal and a second scan control terminal. The input circuit is configured to write a first voltage provided by the first voltage terminal into the pull-up node in response to a start signal inputted to the input terminal. The output circuit is configured to output a first clock signal from the first clock terminal via the first output terminal, when the pull-up node is at the first voltage.

    Abstract: Provided are a driving method, a gate drive unit and a display touch device. The driving method is applied to the gate drive unit in the display touch device. The gate drive unit includes at least one pull-down circuit. The pull-down circuit is coupled with a pull-up node and a pull-down voltage terminal, and is configured to control connection or disconnection between the pull-up node and the pull-down voltage terminal; one frame of image display time includes a display phase and a touch phase that are alternately set, and at least one of the touch phase is set between two adjacent display phases. The driving method includes: during the touch phase, controlling, by the at least one pull-down circuit, the disconnection between the pull-up node and the pull-down voltage terminal. The problem of a screen flashing phenomenon of existing display touch devices during the touch phase is solved.
