Abstract: The present disclosure provides a display panel and a display device. The display panel and display device include a first substrate and a second substrate positioned opposite the first substrate. The first substrate includes first binding pin, and the second substrate includes second binding pin. The second substrate further includes at least one protruding portion and at least one recessed portion, the second binding pins are located on the protruding portion, and the first binding pins are exposed from the recessed portion. Such configuration reduces a total width of a binding region of the display panel and the display device, achieves a narrow border, and improves a display area occupation ratio.

Abstract: A display panel and a display device are provided. The display panel is divided into a display region and a non-display region, wherein the display panel includes: a first blocking wall arranged in the non-display region and surrounding the display region; a bending part; and an electrostatic protection unit arranged in a part of the non-display region corresponding to the bending part and located on a side of the first blocking wall facing away from the display region. By the arrangement of the electrostatic protection unit, problems such as breakdown of the transistors due to electrostatic accumulation caused by bending operation of the display panel, as well as encapsulation structure failure due to damage to the first blocking wall can be avoided.

Abstract: Display panel and display device are provided. The display panel includes scan lines and a scan driving circuit including shift registers in a cascaded configuration and multiplexers. One shift register is connected to one multiplexer. One multiplexer is connected to M scan lines and includes M control units connected with the scan lines in a one-to-one correspondence. Output terminals of switch branches in a control unit are connected to one scan line. An input terminal of a main switch branch is connected to an output terminal of the shift register. An input terminal of an auxiliary switch branch is connected to a first signal line. In one scanning period, in M consecutive time stages, a signal from each shift register to the multiplexer includes effective voltage levels; the main switch branches in the control units are switched on sequentially, and output the scanning signal to the M scan lines sequentially.
