Protective structure and electronic device with the same

1. A protective structure, comprising:

an auxiliary layer having a first surface and a second surface opposite to the first surface; and

a coating layer located on the second surface of the auxiliary layer, wherein the second surface of the auxiliary layer is closer to the coating layer than the first surface of the auxiliary layer, and a Young's modulus of the auxiliary layer is greater than a Young's modulus of the coating layer, and the auxiliary layer and the coating layer comprise a same host material.

2. The protective structure of claim 1 , wherein the auxiliary layer comprises an organic material doped with an inorganic material, the coating layer comprises an organic material, and the organic material of the auxiliary layer is the same as the organic material of the coating layer.

3. The protective structure of claim 2 , wherein the inorganic material is a nanoparticle, and the nanoparticle comprises silicon dioxide, titanium oxide, zirconium oxide, or a combination thereof.

4. The protective structure of claim 1 , further comprising:

a substrate disposed on the first surface of the auxiliary layer; and

an optical structure layer, wherein the substrate is located between the auxiliary layer and the optical structure layer.

5. The protective structure of claim 1 , further comprising:

a substrate disposed on the first surface of the auxiliary layer.

6. An electronic device, comprising:

the protective structure of claim 1 ; and

an electronic element disposed on the first surface of the auxiliary layer.

7. An electronic device, comprising:

the protective structure of claim 1 ;

an electronic element; and

a substrate, wherein the substrate is sandwiched between the coating layer and the electronic element.

8. An electronic device, comprising:

the protective structure of claim 4 ; and

an electronic element disposed on a surface of the optical structure layer away from the substrate.
