Abstract

The invention provides a micro OLED display apparatus. The display apparatus comprises a substrate, an OLED device arranged on the substrate and a thin film packaging layer for packaging the OLED device; the thin film packaging layer is an inorganic thin film packaging layer; the inorganic thin film packaging layer has at least two inorganic layers stacked in sequence; and the adjacent inorganic layers are in opposite stress directions. The invention also provides a manufacturing method of the micro OLED display apparatus. By depositing multiple inorganic layers on the substrate and the OLED device, packaging of the OLED device is realized, and by controlling the adjacent inorganic layers to be in opposite stress directions, stress balance out between the adjacent inorganic layers can be realized, so as to obtain the thin film packaging layer with small thickness, low stress and low water vapor transmittance through deposition, and the process is simple; and the thickness of the thin film packaging layer of the micro OLED display apparatus manufactured by the method is reduced, so that light output crosstalk is reduced.

Description

technical field [0001] The invention relates to the technical field of organic photoelectric devices, in particular to a micro OLED display device and a manufacturing method thereof. Background technique [0002] OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) device has excellent performance such as fast response speed, wide viewing angle, high brightness, low power consumption, etc., and is a self-luminous device. It is considered to be a next-generation display technology with great development prospects. . [0003] Silicon-based microdisplay is a high PPI (Pixels Per Inch) display device. At present, two color realization schemes, planar RGB structure and white OLED plus RGB filter, are mainly used to realize color display. For the planar RGB structure, the parallel RGB sub-pixels are combined into color pixels. The RGB sub-pixels respectively emit light with variable brightness, and present colored light with different brightness after spatial color...
