Abstract

The present invention provides an organic light-emitting diode display substrate, a manufacturing method therefore, and a display device thereof. The organic light-emitting diode display substrate comprises a substrate, an organic light-emitting diode device located on the substrate and a film encapsulation layer. The film encapsulation layer is configured to package the organic light-emitting diode device, and includes at least one inorganic thin layer and at least one organic thin layer which are mutually and alternatively arranged and a hydrophobic retaining wall with a micro-nano structure arranged on the substrate and located at the periphery of the film encapsulation layer. The hydrophobic retaining wall is formed prior to formation of the organic thin layer, and is able to block the fluidity of the ink used for ink-jet printing when a printing technology is employed to prepare the organic thin layer so as to restrict the climbing distance of the organic thin layer and provide technology guarantee for the narrow-edge framing of displaying products of a soft organic light-emitting diode.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light emitting diode display substrate, a manufacturing method thereof, and a display device. Background technique [0002] Encapsulation technology is a key technology for organic light-emitting diode (OLED) display products. Currently, almost all display panel manufacturers are developing thin film encapsulation (TFE). The thin-film packaging structure is generally a multi-layer thin-film stack structure of two or more layers, which can be divided into two types: inorganic thin-film layers and organic thin-film layers according to their functions. [0003] The main function of the inorganic thin film layer is to block water and oxygen, and the main function of the organic thin film layer is to provide planarized film deposition conditions for the subsequently formed inorganic thin film layer and provide excellent particle coating effect. The formation methods of or...
