Abstract: A display panel and a display device are provided. The display panel includes multiple pixel units. In each of the pixel units, the area of an opening region of at least one sub-pixel is different from the area of an opening region of other sub-pixels. There is an adjustment capacitance between the drain of the thin film transistor and/or the first electrode in each sub-pixel and the scan line corresponding to the sub-pixel, and the sub-pixel having a smaller area of the opening region corresponds to a smaller value of the adjustment capacitance. By adjusting the value of the adjustment capacitance corresponding to the sub-pixels with different areas of opening regions, the optimal Vcom of all the sub-pixels is the same, so that all the sub-pixels operate under the same optimal Vcom.

Abstract: Provided are a shift register, a gate drive circuit, a display panel and a driving method. The shift register includes a first output module, a second output module, a first node, a second node, a first power supply signal terminal, a first clock signal terminal and a scan output terminal. The first output module and the second output module are electrically connected to the scan output terminal. The first output module is further electrically connected to the first power supply signal terminal and the first node. The first node is configured to control a conduction state of the first output module. The second output module is further electrically connected to the first clock signal terminal and the second node. The second node is configured to control a conduction state of the second output module. There is no capacitor in the first output module and/or the second output module.

Abstract: The disclosure provides a display panel and a method for driving the display panel. The display panel includes a display area and a peripheral area surrounding the display area, and the display area includes one first display area and at least one second display area. The design according to embodiments of the disclosure release enough space occupied by the peripheral area at one side of the at least one second display area far away from the first display area, thus increasing display area in desired direction and a screen-to-total face ratio.

Abstract: A display substrate, a display module and a control method are provided in the present disclosure. The display substrate includes a first substrate and a second substrate. The first substrate includes a base substrate, conductive pads, a first switch unit group electrically connected to the conductive pads and signal wires, and a second switch unit group electrically connected to the conductive pads. The display substrate includes a substrate detection phase where all second switch units are cutoff, all first switch units are conducting, and an external detection device input a first detection signal to the substrate through the conductive pads and all first switch units. When the first switch unit group is conducting, the conductive pads are used for substrate detection, and when the second switch unit group is cutoff, the conductive pads in a same pad region are connected each other to be multiplexed as electrostatic conductive pads.
