Flexible display panel and manufacturing method thereof

Abstract

The invention provides a flexible display panel and a manufacturing method thereof. The flexible display panel comprises a TFT substrate, an anode, a pixel definition layer, a light emitting device layer, a plurality of isolation columns, an auxiliary organic layer and a thin film packaging layer. The auxiliary organic layer is arranged on the pixel definition layer and the light emitting device layer; the thin film packaging layer comprises a first inorganic packaging layer, an organic packaging layer and a second inorganic packaging layer which are sequentially stacked on the auxiliary organic layer. The method comprises the steps of preparing the light emitting device layer; arranging the auxiliary organic layer with a proper thickness on the pixel definition layer and the light emitting device layer to completely cover Particle and burrs generated by a mechanical arm and a fine mask plate in the film forming process of the light emitting device layer; and arranging the thin film packaging layer on the auxiliary organic layer. The first inorganic packaging layer is prevented from being broken or cracked, the blocking effect of the thin film packaging layer on water vapor and oxygen can be effectively ensured, and the packaging performance is improved.

Description

Technical field [0001] The present invention relates to the field of display technology, in particular to a flexible display panel and a manufacturing method thereof. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display technology has a wide range of application prospects due to its advantages of high response, high contrast, flexibility, etc. However, due to the effect of water vapor and oxygen, light-emitting devices will appear The phenomenon of corrosion damage, so choosing a better packaging method is particularly important for OLED devices. [0003] At present, Thin-Film Encapsulation (TFE) is an encapsulation method widely used in the production of OLED displays. It uses an inorganic / organic / inorganic three-layer barrier laminated structure to cover the light-emitting device to increase water and oxygen. The channel in turn blocks the purpose of water and oxygen. However, because the film layers of the light-emitting devic...

AI Technical Summary

Problems solved by technology

[0005] The flexible display panel and its manufacturing method provided by the present invention solve the problem of the formation of large particles and burrs due to the fact that the light-emitting device layer of the existing flexible display panel is easily damaged by the mechanical arm and the fine mask plate during the film formation process. , leading to faults or cracks in the first inorganic encapsulation layer, which affects the technical problems of the encapsulation performance of the thin film encapsulation layer
