摘要： Disclosed are a first shift register, a driving method for the same, a gate driving circuit and a display device. The first shift register includes a first unit, M second units and N third units. A first signal output terminal of the first unit is connected with M second signal input terminals of the M second units. A second signal output terminal of each second unit is connected with third signal input terminals of N/M third units respectively. The first unit outputs a voltage of a first clock signal terminal to the first signal output terminal and a fourth signal output terminal under the control of a first signal input terminal and a second clock signal terminal and outputs a voltage of a first voltage terminal to the first signal output terminal and the fourth signal output terminal.

摘要： Disclosed are a display substrate (10) and a display device. The display substrate (10) includes at least one irregularly-shaped pixel (103), and a shape of a boundary line of a side, proximal to a peripheral region (101b), of each irregularly-shaped pixel (103) matches with a shape of a boundary line (101a1) of an irregularly-shaped display region (101a) in a base substrate (101), such that the irregularly-shaped pixel (103) does not go beyond the irregularly-shaped display region (101a) of the display substrate (10), a narrow bezel of the display substrate (10) can be realized conveniently, and an image displayed at the boundary line (101a1) of the irregularly-shaped display region (101a) may be prevented from being in a zigzag shape, thereby ensuring a display effect of the display device. Moreover, because an area of an orthographic projection of the irregularly-shaped pixel (103) on the base substrate (101) is smaller than an area of an orthographic projection of a rectangular pixel (102) on the base substrate (101), an area of an opening (a) formed by a black matrix layer (104) in a region where each rectangular pixel (102) is disposed is larger than an area of an opening (b) formed by the black matrix layer (104) in a region where any irregularly-shaped pixel (103) is disposed, such that a smooth transition of luminance of light emitted by the irregularly-shaped pixel (103) and the rectangular pixel (102) can be ensured, and the luminance uniformity of the display device is better.

摘要： Embodiments of the present disclosure relate to a data driving circuit, a driving method thereof, an array substrate, and a display panel. The data driving circuit includes a data driver, a multiplex circuit, and a control circuit. The data driver includes M data output terminals, and each of the data output terminals provides a data signal to L data lines via the multiplex circuit. The multiplex circuit includes M×L switch groups, and each of the switch groups includes N switch tubes and is coupled between one data line and the corresponding data output terminal. Each switch tube is coupled to one of L×N gate control terminals of the control circuit. Each gate control terminal is coupled to M switch tubes that are spaced apart from each other by (L×N×1) switch tubes. In the embodiments, M is an integer, and L and N are integers greater than or equal to 2.
