Problems solved by technology

[0003] At present, flexible OLED screens are mainly encapsulated by thin-film encapsulation (TFE). However, when the current thin-film encapsulation layer is bent, the film layer (especially the inorganic encapsulation layer) has a large stress and is prone to damage, resulting in water oxygen Intrusion, resulting in package failure, seriously affecting the service life of the display screen

Abstract

The invention relates to a display device and a preparation method thereof, and a display device. The display device comprises a substrate, a pixel definition layer, a light emitting unit and a thin film packaging structure, wherein the pixel defining layer is located on the substrate and defines a pixel area and a non-pixel area, and the light emitting unit is arranged in the pixel area; the thinfilm packaging structure is located on the substrate and covers the pixel definition layer and the light emitting unit; the thin film packaging structure comprises a plurality of inorganic packaginglayers arranged in a stacked mode and organic packaging layers arranged between every two adjacent inorganic packaging layers, a protruding structure is arranged on the surface, away from the pixel definition layer, of at least one organic packaging layer, and the protruding structure on the organic packaging layers is arranged in the non-pixel area. The display device has high bending performance.

Description

technical field [0001] The invention relates to the technical field of electronic devices, in particular to a display device, a preparation method thereof, and a display device. Background technique [0002] Organic Light Emitting Diode (OLED) display technology has been paid attention to due to its excellent luminous performance and wide application prospects. In particular, flexible OLED display technology has become the new favorite of the times due to its advantages of low power consumption, small thickness and bendability, and has become one of the important pillars of the future display industry. [0003] At present, flexible OLED screens are mainly encapsulated by thin-film encapsulation (TFE). However, when the current thin-film encapsulation layer is bent, the film layer (especially the inorganic encapsulation layer) has a large stress and is prone to damage, resulting in water oxygen Intrusion, resulting in package failure, seriously affecting the service life of ...
