Abstract

The invention provides a display panel and electronic equipment. The display panel comprises a substrate, a dam, a planarization layer and a packaging structure layer, the substrate comprises a display area and a non-display area; the planarization layer is arranged on one side of the substrate and partially located in the non-display area. The dam is arranged on the side, away from the substrate, of the planarization layer and located in the non-display area. The packaging structure layer covers the display area and at least part of the non-display area, and the part, located in the non-display area, of the packaging structure layer is arranged on the side, away from the substrate, of the dam and makes contact with the surface of the planarization layer, so that direct lap joint between the packaging structure layer and a metal layer of the display panel is avoided; therefore, the packaging structure layer is prevented from falling off in the high-temperature and high-humidity verification process due to the holes in the middle of the metal layer, and the phenomenon of display black spots is prevented.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and electronic equipment. Background technique [0002] Since the organic luminescent material in the display panel is very sensitive to external environments such as water and oxygen, the display panel needs to be packaged to prevent the intrusion of air and water vapor, so as to ensure the reliability of the display panel. [0003] Thin-Film Encapsulation (TFE) or glass frit (Frit) encapsulation is usually performed on the display panel. Taking thin film packaging as an example, the existing thin film packaging structure is prone to display black spots, which further affects the stability of the display panel. Contents of the invention [0004] In view of this, the present application provides a display panel and an electronic device to solve the technical problem that black spots on the display are easy to appear in the thin film packaging in the prior art....
