Abstract: Provided is a display panel. The display panel includes: a base provided with a display region, a hole region, and an isolation region disposed between the display region and the hole region. The display region and the isolation region at least partially surround the hole region. The display panel includes: a planarization layer disposed on the base, a pixel defining layer and a spacer layer which are disposed on the planarization layer, and an inorganic material layer covering the planarization layer, the pixel defining layer and the spacer layer. The isolation region is provided with at least one blocking groove and at least one blocking wall. The blocking groove is formed in the planarization layer, and the blocking wall includes the planarization layer and the inorganic material layer formed on the planarization layer.

Abstract: The present application provides display substrates and their manufacturing methods, and display devices. A display substrate includes a base substrate, an encapsulation layer, a filter layer and optical film layers. The encapsulation layer is located on the base substrate. The filter layer is located in the encapsulation layer. The filter layer includes black matrixes. The black matrixes include black matrix openings. The optical film layers are located on a side of the encapsulation layer away from the base substrate. The optical film layers are configured to transmit part of incident light and absorb part of the incident light. A light transmittance of the optical film layers is larger than that of the black matrixes. The optical film layers include optical film layer openings. Projections of the optical film layer openings on the base substrate are located within projections of the black matrix openings on the base substrate.

Abstract: This disclosure provides a packaging structure for a display substrate, a packaging method and a display device. The packaging structure for the display substrate includes a base substrate, a light-emitting device arranged on the base substrate, and a packaging thin film covering the light-emitting device. The packaging thin film includes an inorganic thin film and an organic thin film that are laminated, and the organic thin film is arranged on a surface of the inorganic thin film away from the base substrate. The packaging thin film includes a central region and a peripheral region surrounding the central region, the inorganic thin film located in the central region has surface energy greater than that of the inorganic thin film in the peripheral region, and the organic thin film in the central region has a thickness less than that of the organic thin film in the peripheral region.

Abstract: A display region includes: a first display region including a first thin film encapsulation structure; a second display region including a second thin film encapsulation structure; and a transition display region including a third thin film encapsulation structure.
