Abstract: A display panel, a method for manufacturing the display panel, and a display apparatus are described. In an embodiment, the display panel includes a display area and a non-display area; a substrate; an organic layer located at a side of the substrate and located in the display area and the non-display area, in which the organic layer includes a first portion located in the non-display area; and an organic layer protection structure located on a surface of the organic layer facing away from the substrate. In an embodiment, the organic layer protection structure includes a first structure in the display area and a second structure in the non-display area. In an embodiment, the second structure overlaps the first portion in a direction perpendicular to a plane of the substrate. In an embodiment, the first structure and the second structure are in direct contact with the organic layer.

Abstract: A driving circuit includes a first power signal terminal, a second power signal terminal, a first driving transistor, a light-emitting element, a first storage module, a first boost module, a first light-emitting control module, and a data write module. The driving circuit includes a data write stage, a boost stage, and a light-emitting stage in a same frame. At the data write stage, the data write module transmits a first data signal to the first boost node. At the boost stage, the boost signal terminal transmits a boost signal to the first boost module to increase a potential of the first boost node. At the light-emitting stage, the first light-emitting control module is in conduction, and a signal of the first boost node is transmitted to the first node.
