Abstract

The present invention provides an OLED display panel and a manufacturing method thereof. The OLED display panel includes a substrate including a display area, and a non-display area located outside the display area; an OLED layer disposed in the display area of the substrate; a packaging portion disposed above the OLED layer and including an organic layer and at least one retaining wall disposed around the organic layer. The organic layer is located within the enclosure space of the retaining wall. By disposing the retaining wall for stopping the overflow of an organic solution above the substrate, the precision of the OLED display panel is improved, the water oxidation resistance of the OLED display panel is improved, and the quality of the OLED display panel is improved.

Description

technical field [0001] The invention relates to the display field, in particular to an OLED display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) display technology is different from traditional LCD display technology. It does not require a backlight and has self-illuminating characteristics. It uses a very thin organic material coating and a glass substrate. When there is current When passed through, these organic materials emit light. Moreover, the screen can be made lighter and thinner, with a wider viewing angle, and can significantly save power. [0003] The packaging part of OLED display panels usually adopts a laminated structure in which inorganic layers, organic layers and inorganic layers are distributed in sequence; among them, the inorganic layer structure is mainly used to prevent the intrusion of water and oxygen, and the organic layer structure is used to improve the stress between the layer and fi...
