Abstract

The invention discloses an organic light-emitting component, a preparation method thereof, and a display device. The organic light-emitting component includes a substrate, an intermediate structural layer, and a thin-film encapsulation structural layer. The substrate includes a first surface; the intermediate structural layer is arranged on the first surface, and the intermediate structural layer The non-display area is provided with an anti-diffusion stop structure, which is arranged at intervals on the periphery of the display area; the non-display area is also provided with an anti-shrink stop structure, and the anti-shrink stop structure is arranged between the display area and the anti-diffusion Between the stopper structures, the intermediate structure layer also includes a planarization layer and a display structure part and an anti-shrinkage stopper structure arranged on the planarization layer at intervals, and the anti-shrinkage stopper structure is arranged on the periphery of the display structure part; the film encapsulation structure layer The anti-shrink stopper structure is arranged between the thin film encapsulation structure layer and the planarization layer, and the free end of the anti-shrinkage stopper structure extends into the thin film encapsulation structure layer.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting component and a preparation method thereof. The invention also relates to a display device with the organic light-emitting component. Background technique [0002] In the thin film encapsulation process of the organic light-emitting display device, the organic layer is generally made of ultraviolet light-cured organic material, and the organic layer can usually be formed between the first inorganic layer and the second inorganic layer by inkjet printing. Under the action of inherent surface tension, the organic layer exhibits edge shrinkage after being irradiated with ultraviolet light, and forms a raised convex film layer structure at the edge caused by the shrinkage. In order to improve the convex film layer caused by shrinkage, it can usually be improved by increasing the climbing distance from the edge of the organic layer to the highest point and ...
