摘要： A substrate in an array substrate includes a light aperture region and a winding region arranged around the light aperture region. On the substrate, an orthographic projection of a first winding in each first signal line is overlapped with an orthographic projection of a second winding in a corresponding second signal line. In this way, the distance between two adjacent signal lines in the winding region is larger, and the parasitic capacitance generated between them is smaller.

摘要： The present disclosure provides a display panel, a method of driving the display panel and a display device. Each signal input sub-circuitry of the display panel includes at least two transistors. A same control signal is applied to control signal lines corresponding to a same signal input sub-circuitry, different control signals are applied to control signal lines corresponding to different signal input sub-circuitries, and time periods within which the different control signals are at active levels are staggered from each other. A sum of width-to-length ratios of channels of the at least two transistors is equal to a first predetermined value, and an overlapping area of the gate electrode of each of the at least two transistors relative to an active layer of the transistor is smaller than a second predetermined value in a direction perpendicular to a base substrate of the display panel.
