Abstract

The invention provides a thin film packaging structure, a display device and a packaging method of the display device. The thin film packaging structure has a middle part corresponding to a display region of a to-be-packaged substrate, and an edge part corresponding to a peripheral region of the to-be-packaged substrate; the thin film packaging structure comprises a first inorganic thin film usedfor covering the to-be-packaged substrate, an organic thin film formed on the first inorganic thin film, and a second inorganic thin film for covering the organic thin film, wherein the thin film packaging structure also comprises a blocking structure used for blocking a fluid organic material in formation of the organic thin film; and the blocking structure is positioned on the edge part and surrounds the middle part. By virtue of the thin film packaging structure, complete flowing and diffusing of the organic material in the thin film packaging structure can be ensured, complete planarization in an AA region can be realized, the organic material can be only limited in a certain region outside the AA region for flowing and diffusing, and a narrow framer is realized.

Description

technical field

[0001] The invention relates to the field of display technology, in particular to a thin film packaging structure, a display device and a packaging method. Background technique

[0002] OLED is an Organic Light-Emitting Diode (Organic Light-Emitting Diode), which has the characteristics of self-illumination, high brightness, wide viewing angle, high contrast, flexibility, and low energy consumption. It began to gradually replace traditional liquid crystal displays and was widely used in mobile phone screens, computer monitors, full-color TVs, etc.

[0003] OLED display technology is different from traditional LCD display methods. It does not require a backlight, and uses very thin organic material coatings and glass substrates. When an electric current passes through, these organic materials will emit light. However, since organic materials are easy to react with water and oxygen, as a display device based on organic materials, display screens have very high...
