摘要： Disclosed is a pixel circuit arranged in a display substrate, which comprises a first driving mode and a second driving mode. Content displayed in the display substrate comprises multiple display frames. In the first driving mode and the second driving mode, the display frames comprise refresh frames. A signal of a second scanning line is the same as that of a third scanning line. The time of which the signal of the second scanning line is an active level signal comprises a first refresh time period, a second refresh time period and a third refresh time period, which sequentially occur at intervals. During the second refresh time period, a signal of a first scanning line is an inactive level signal. The voltage of a signal at a reset voltage end is a positive voltage, and the voltage of a signal at a first initial voltage end is a negative voltage.

摘要： A wiring structure, a display substrate and a display device are provided, which belongs to the field of display technology. The wiring structure includes a plurality of hollow patterns connected successively. Each of the hollow patterns includes a first conductive part having a first pattern and a second conductive part having a second pattern. The first conductive part and the second conductive part are connected with each other, and the first pattern and the second pattern have different shapes. Because the wiring structure includes a plurality of hollow patterns connected successively, and the first conductive part and the second conductive part in each hollow pattern have different shapes, even if the conductive part of one shape in the wiring structure is broken in the process of bending, stretching and twisting, the conductive part of the other shape can also ensure good conductivity for the wiring structure.
