Abstract

The invention relates to a display screen and a preparation method thereof. The display screen has a non-display area, and the non-display area includes an effective packaging area close to the packaged device, and a packaging shadow area located on the periphery of the effective packaging area; the packaging shadow area includes: a supporting base, on which there is a an open groove; and a thin film encapsulation structure formed on the support base, the thin film encapsulation structure is broken at the groove. The display screen applying the technical solution of the present invention can cut off the path of laser thermal radiation and stress transmission when cutting the display body because the groove can disconnect the film packaging structure, effectively avoiding cracks on the film packaging structure, Therefore, the reliability of the thin film packaging can be improved, which is beneficial to the application.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display screen and a preparation method thereof. Background technique [0002] Thin-film encapsulation technology is especially suitable for some special occasions that cannot be realized by traditional capping encapsulation, such as encapsulation of flexible organic light-emitting diodes (Organic Light-Emitting Devices, OLEDs) and flexible organic solar cells. However, in the process of cutting the film-encapsulated display body, it is easy to damage the film-encapsulation structure and affect the reliability of the film-encapsulation. Contents of the invention [0003] Based on this, it is necessary to provide a display screen capable of improving the reliability of thin film packaging and a preparation method thereof for the problem of how to improve the reliability of thin film packaging. [0004] A display screen, the display screen has a non-display area, the non-disp...
