Abstract

The invention provides an OLED display panel and a manufacturing method thereof, comprising an OLED substrate and a packaging part arranged on the OLED substrate. The OLED substrate comprises a substrate and an OLED layer, wherein the substrate comprises a display area and an edge area surrounding the display area, and the OLED layer is arranged in the display area; The encapsulation part comprises a barrier body and an encapsulation layer. the barrier body is arranged in the edge region and comprises at least one coil of barrier ring. The barrier ring surrounds the OLED layer and spaced fromthe OLED. The encapsulation layer is arranged above the barrier body. By providing a barrier including at least one loop of barrier coils in an edge region of an OLED substrate, The barrier and the inorganic layer are combined to enhance the water-oxygen resistance of the side surface of the OLED display panel, thereby avoiding the multi-layer photomask manufacturing process and simplifying the manufacturing process of the OLED display panel on the basis of improving the water-oxygen resistance of the packaging structure omni-directionally.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Organic light emitting diode (OLED for short) has excellent characteristics such as self-luminescence, low energy consumption, wide viewing angle, rich colors, fast response, etc., and OLEDs can be used to prepare flexible display devices. OLED has therefore aroused great interest in the scientific research community and the industry, and is considered to be a very promising next-generation technology. [0003] Currently, OLED screens widely used in the display field generally adopt a top-emitting (top-emitting) device structure, and an OLED device is composed of an anode, an organic layer and a cathode. Wherein, the organic layer includes a hole injection layer, a hole transport layer, an organic light emitting layer, an electron transport layer and an electron injection layer. [0004] Si...
