Abstract

The invention provides an OLED panel and a fabrication method thereof. The OLED panel comprises a display region and a through hole, wherein the display region encircles a part around the through holeand comprises a package region, the package region encircles a circumferential side of the through hole, the package region comprises a hybridization layer, the hybridization layer is used for preventing water and oxygen invasion, and the hybridization layer covers the package region and a hole wall of the through hole. By forming the hybridization layer on an organic structure layer of the package region, the effect of preventing water and oxygen from being immersed into an organic light-emitting layer is achieved.

Description

technical field [0001] The present application relates to a display technology, in particular to an OLED panel and a manufacturing method thereof. Background technique [0002] In the existing hole-digging organic light emitting diode (Organic Light Emitting Diode, OLED) panel, the OLED light-emitting material layer is extremely sensitive to water and oxygen, and usually requires a very high water-blocking thin film encapsulation (Thin Film Encapsulation, TFE) film layer. Cover protection. Laser cutting will destroy the integrity of the TFE film layer, resulting in the exposure of OLED light-emitting material layers (such as cathode, organic passivation layer, etc.) at the edge of the hole, and the intrusion of water and oxygen will cause the entire display device to fail to display. Contents of the invention [0003] The embodiments of the present application provide an OLED panel and a manufacturing method thereof, so as to solve the technical problem that the integrity...
