Embodiment Construction

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0041] Please refer to figure 1 , figure 1 It is a top view of a stretchable display substrate in the related art, which includes: an island region (display unit region) 10, a bridge region (connecting unit region) 20 and a hollow region 30, and adjacent island regions 10 pass through Bridge area 20 is connected. The island area is used for setting a light emitting unit, and the light emitting unit includes an organic light emitting pattern.

Abstract

The invention provides a stretchable display substrate, a manufacturing method thereof and a stretchable display device, the display substrate comprises a plurality of island areas arranged in an array and bridge areas used for connecting the adjacent island areas, and the island areas comprise display areas and non-display areas located on the peripheries of the display areas; the non-display area is internally provided with a first groove arranged around the display area, an organic light-emitting pattern arranged in the first groove and a packaging pattern arranged in the first groove and covering the organic light-emitting pattern in the first groove. In the present invention, an organic light-emitting material can be evaporated by adopting a fine metal mask plate of which the whole mask plate is provided with sub-pixel openings; the manufacturing difficulty of the fine metal mask plate and the color mixing phenomenon in the evaporation process are reduced, in the non-display areaof the island area, the organic light-emitting material can be evaporated into the first groove, then the organic light-emitting material in the first groove is packaged through the packaging pattern,and therefore the packaging effect is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a stretchable display substrate, a manufacturing method thereof, and a stretchable display device. Background technique [0002] Stretch display, as a kind of "black technology", has come out, adding more options to flexible displays. At present, stretched display devices mostly include: an island area (display unit area), a bridge area (connecting unit area) and a hollow area. Adjacent island areas are connected by a bridge area, and a certain tensile performance can be achieved by stretching the hollow area. . There are several sub-pixels in the island area, and the side length of the island area generally ranges from 50 to 2000um. Each island needs to be packaged independently. The non-display area inside the island area is only 60 to 180um, which adds a huge challenge to the packaging reliability. [0003] The organic light-emitting (such as RGB) ...
