Abstract: A touch display panel is provided. The touch display panel includes: a substrate; a thin-film transistor array, an organic light-emitting unit and a thin-film encapsulation layer which are successively laminated on the substrate; and a touch electrode arranged at a side, which is facing away from the organic light-emitting unit, of the thin-film encapsulation layer. The touch display panel includes a display area and a non-display area surrounding the display area. The non-display area has a first dam surrounding the display area and a second dam surrounding the first dam; the non-display area includes a bonding area and border areas disposed at two sides of the bonding area; and at least in the bonding area, organic material fills a region between the first dam and the second dam and fills a region at a side close to the display area of the first dam.

Abstract: Provided are a flexible display panel and a flexible display device, in which a non-display area surrounds a display area. A concave area protrudes along a direction away from interior of display area. A convex area has a folding axis parallel to a first edge. The non-display area includes a fan-out area, in which lead wires are provided. Each lead wire has a first end and a second end. There are signal traces each extending along a first direction provided in display area. The signal traces are electrically connected to first ends of lead wires. The convex area and concave area are arranged along a second direction. The second direction intersects first direction. A driving chip is included, which is a ball grid array package driving chip and is arranged in concave area where lead wires are away from first edge and electrically connected to second ends of lead wires.
