Problems solved by technology

In the film-encapsulated island-bridge structure, since the water-blocking layer (i.e., the inorganic layer) covers the entire surface of the bridge structure and the island structure, and the water-blocking layer (made of SiNx, SiON, etc.) is a brittle material, the stretchable amount< 1%, so the water-blocking layer bounds the stretchable amount of the bridge, and the bridge structure is a stress concentration area when it is stretched, the water-blocking layer on the bridge structure is easy to break, and the bridge structure will break together (ie: the connecting line breaks ), causing product damage

Abstract

The invention discloses a stretchable display module, a manufacturing method thereof and a display device. The stretchable display module comprisesa substrate having a plurality of islands arranged inan array and separated from each otherand a plurality of bridges for connecting the islands, first stretchable layers disposed on the plurality of bridges and a water blocking layer disposed on the substrate, a plurality of partition grooves are formed in the first stretchable layer on at least one bridge, the plurality of partition grooves separate the water blocking layer, so that the water blocking layer on the bridge is broken or thinned at the partition grooves, the water blocking layer less binds the bridge and the first stretchable layer on the bridge, the bridge is less prone to breakage when stretched, and the stretchable amount of the first stretchable layer on the bridge and the bridge is also increased.

Description

technical field [0001] This article relates to the technical field of display devices, in particular to a stretchable display module, a method for making a stretchable display module and a display device. Background technique [0002] Stretchable device structures include hard open grid structures, island bridge structures, hard film buckling structures, etc. Among them, the island bridge structure is widely favored due to its unique tensile properties. The "island" structure in the island-bridge structure is a rigid area, including a display unit (ie, light-emitting unit) with a small amount of stretch; the "bridge" structure is an elastic area surrounding the rigid area, including connecting lines. When stretching, the stretching amount of the bridge structure is greater than that of the island structure, so the display unit of the island structure is not easily damaged. In the island-bridge structure of thin-film encapsulation, since the water-blocking layer (ie: inorga...
