Claim 0:
1. A local stretch packaging structure, comprising:
a substrate;
a flexible electronic element, disposed on the substrate;
a plurality of light-emitting display elements, disposed on the flexible electronic element; and
a packaging layer, wherein the packaging layer comprises:
a packaging area, continuously covering an upper surface and sidewalls of each one of the plurality of light-emitting display elements; and
a non-packaging area, directly covering the flexible electronic element that is not disposed with the plurality of light-emitting display elements, wherein some portions of the non-packaging area are respectively located between every adjacent two of the light-emitting display element;
wherein at a processing temperature of the substrate, and the processing temperature is from 80° C. to 180° C.:
when a storage modulus of the substrate is higher than a storage modulus of the packaging layer, an elasticity of the non-packaging area is higher than 30%, and the elasticity of the non-packaging area increases with the increase of the storage modulus difference between the substrate and the packaging layer;
when the storage modulus of the substrate is lower than the storage modulus of the packaging layer, the elasticity of the non-packaging area is lower than 30%, and the elasticity of the non-packaging area decreases with the increase of the storage modulus difference between the substrate and the packaging layer;

wherein the storage modulus of the substrate at the processing temperature is from 1 MPa to 20000 MPa.
