Abstract

The embodiment of the invention provides an OLED display panel and a preparation method thereof, a package portion failure determination method, and a display device, and relates to the field of display technology. The problem is solved that occurrence of package structure failure cannot be determined in the manufacturing process of an OLED display in the prior art. The OLED display panel comprises an OLED light-emitting component and a package portion which are located on the first substrate, the OLED light-emitting component is located at a luminous zone of the OLED display panel, and the OLED light-emitting component is coated with the package portion; the OLED display panel further comprises a water vapor detection portion located on the first substrate, the water vapor detection device is arranged between an edge of the luminous zone and an edge of an inner side of the package portion, the water vapor detection portion comprises a hydrophobic film layer and a hydrophilic film layer arranged in a stacking mode, after the hydrophilic film layer absorbs water, and wrinkles are generated at an interface of the hydrophobic film layer and the hydrophilic film layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a preparation method, a method for judging failure of a packaging part, and a display device. Background technique [0002] OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display is a self-luminous display with fast response, high contrast, wide viewing angle, etc. Advanced liquid crystal displays are widely used in mobile phone screens, computer monitors, full-color computers, etc. According to different driving methods, OLED displays can be classified into PMOLED (Passive-matrix Organic Light Emitting Diode, passively driven organic light emitting diode) and AMOLED (Active-matrix Organic Light Emitting Diode, actively driven organic light emitting diode). [0003] At present, the bottleneck restricting the development of OLED display industry is mainly its short lifespan. Taking an AMOLED display as an example, the AMOLED display ...
