Abstract: A display panel, a folding method thereof, and a display device are provided. The display panel includes a display region, a non-display region, and a bending region. Side edges of the bending region include bending points, the bending points are disposed in the bending region, and the side edges are concaved toward an interior of the bending region at the bending points. During folding, the bending points on the side edges of two sides form at least one guiding axis, which makes the display panel easier to bend, and folding precision and folding effect are good.

Abstract: A display panel has a non-display area comprising a GOA wiring area is provided. The display panel includes GOA wirings disposed in the GOA wiring area, and an electrostatic shielding unit, disposed at least corresponding to the GOA wirings of part of the GOA wiring area. The electrostatic shielding unit is configured to prevent the GOA wirings from being damaged by static electricity.

Abstract: A touch display panel is provided and includes a substrate, a thin-film encapsulation layer, a first dam, a second dam, and a touch control line. The substrate includes an active area and a non-active area. The thin-film encapsulation layer is disposed on, the substrate. The first dam and the second dam are positioned in the non-active area. The first dam and the second dam are disposed on the thin-film encapsulation layer. The thin-film encapsulation layer is bounded by the first dam. The touch control line is disposed on the thin-film encapsulation layer, the first dam, and the second dam. The first dam includes a first protruding portion or a first recessed portion correspondingly at an intersection of the first dam and the touch control line.
