Embodiment Construction

[0031] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0032] During the film formation process of the thin film packaging structure, affected by the shadow effect, the size of the packaging material actually deposited on the array substrate is larger than the opening size of the mask plate. In the process of cutting the display body after fi...

Abstract

The invention relates to a display screen and a preparation method thereof. The display screen has a non-display region; the non-display region comprises an effective packaging region close to a packaged device, and a packaging shadow region positioned on the periphery of the effective packaging region; the packaging shadow region comprises a support base and a thin film packaging structure; a groove for disconnecting the thin film packaging structure is formed in the support base; the thin film packaging structure is formed on the support base; and the thin film packaging structure is disconnected in the position of the groove. By applying the display screen with the technical scheme of the invention, the thin film packaging structure can be disconnected by the groove, so that a laser thermal radiation and stress transport path in cutting the display screen body can be cut off, and cracks generated on the thin film packaging structure can be avoided effectively, thereby improving reliability in thin film packaging and facilitating 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...
