    Abstract: A driver, a display device, and an optical compensation method thereof are provided. The display panel includes sub-pixels arranged in an array. The method includes: receiving an initial gray level of each sub-pixel of a picture to be displayed; determining whether each sub-pixel satisfies a preset determination condition based on the initial gray level of each sub-pixel; if an absolute value of a difference between the initial gray levels of two sub-pixels electrically connected to a same data line and located in two adjacent rows is greater than a preset threshold, it is determined that a sub-pixel in a next row satisfies the preset determination condition; and, in response to determining that a sub-pixel satisfies the preset determination condition, acquiring a first compensation parameter of the sub-pixel, and compensating the initial gray level of the sub-pixel based on the acquired first compensation parameter.

    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.

    Abstract: The disclosure provides a timing control method and a timing control circuit for a display panel, a driving device, and a display device. The method includes: in respective display periods, supplying a data enable signal to a source driving circuit. The source driving circuit supplies a data signal to a plurality of sub-display regions under the control of the data enable signal. The data enable signal is switched between an active level and an inactive level, and the active levels of the data enable signal are in one-to-one correspondence with the plurality of sub-display regions of the display panel. The farther one of the plurality of sub-display regions from the source driving circuit, the longer time period, at an active level, of the data enable signal for controlling the source driving circuit to provide the data signal to at least one row of pixels in the sub-display region is.
