Abstract

The invention discloses a display panel and a manufacturing method thereof, and a display device. The display panel includes a display area, a first non-display area and an accommodation hole, whereinthe first non-display area surrounds the accommodation hole, the display area surrounds the first non-display area, the display panel further includes a substrate, an organic light emitting layer which is on one side of the substrate and includes a first organic light emitting layer located in the display area and a second organic light emitting layer located in the first non-display area, and anencapsulation layer located on the side of the organic light emitting layer away from the substrate, the first non-display area further includes at least one first light-to-heat conversion component,the orthographic projection of the first light-to-heat conversion component on a plane of the substrate and the orthographic projection of the organic light emitting layer on the plane of the substrate do not overlap, the first light-to-heat conversion component is located on the side of the encapsulation layer close to the substrate, and the encapsulation layer covers the first light-to-heat conversion component. The display panel is advantaged in that the path of water and oxygen entering the display area is blocked, and reliability of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, and more specifically, to a display panel, a manufacturing method and a display device. Background technique [0002] Compared with the current mainstream liquid crystal display devices, organic light emitting diode (OLED) display devices have many advantages such as self-illumination, low driving voltage, high luminous efficiency, short response time, high definition and contrast, and wide operating temperature range, and are considered to have potential display device. [0003] OLED display devices generally include: a substrate, an anode disposed on the substrate, an organic light-emitting layer disposed on the anode, and a cathode disposed on the organic light-emitting layer. Wherein the organic light-emitting layer is formed by vapor deposition. In order to prevent water and oxygen from entering the display area and destroying the stability of the OLED display device, it is necess...
