Display panels and display devices

1. A display panel, comprising:

a display substrate; and

an encapsulating unit disposed on the display substrate, the encapsulating unit comprising at least one buffer layer,

wherein the at least one buffer layer comprises a buffer body and a plurality of first buffer particles disposed in the buffer body, the buffer body is deformable under an action of an external force thereby compressing the first buffer particles, and the first buffer particles are elastically deformable or capable of being crushed by compression; and

wherein the at least one buffer layer further comprises at least one second buffer particle disposed within one of the first buffer particles.

2. The display panel of claim 1 , wherein the at least one second buffer particle comprises at least one buffer portion.

3. The display panel of claim 1 , wherein the at least one second buffer particle is an integrated solid sphere comprising a plastic material.

4. The display panel of claim 1 , wherein the at least one second buffer particle comprises a plurality of buffer portions in communication with each other.

5. The display panel of claim 1 , wherein the at least one second buffer particle comprises a plurality of buffer portions that are in contact with each other and are not in communication with each other.

6. The display panel of claim 1 , wherein the at least one second buffer particle comprises a plurality of nesting buffer portions.

7. The display panel of claim 1 , wherein the at least one second buffer particle is elastically deformable or capable of being crushed under an action of an external force.

8. The display panel of claim 1 , wherein at least one of the first buffer particles and the at least one second buffer particle comprises a shell and a buffer core encapsulated in the shell, the shell is elastically deformable or capable of being crushed by compression, and the buffer core is capable of being released from the shell under a condition that the buffer shell is crushed.

9. The display panel of claim 8 , wherein the buffer core comprises a desiccant capable of undergoing a hydrolysis reaction.

11. The display panel of claim 8 , wherein the shell comprises a plastic material having a high light transmittance.

12. A display panel, comprising:

a display substrate; and

an encapsulating unit disposed on the display substrate, the encapsulating unit comprising at least one buffer layer and a thin film encapsulating layer,

wherein the at least one buffer layer comprises a buffer body and a plurality of first buffer particles disposed in the buffer body, the buffer body is deformable under an action of an external force thereby compressing the first buffer particles, and the first buffer particles are elastically deformable or capable of being crushed by compression;

wherein the at least one buffer layer has a thickness in a range from about 4 μm to about 20 μm; and

wherein a diameter of each of the plurality of first buffer particles is a half of a thickness of the at least one buffer layer, and a distribution density of the first buffer particles is in a range from about 500 pcs/mm 2 to about 50000 pcs/mm 2 .

13. The display panel of claim 12 , wherein the at least one buffer layer is stacked on the thin film encapsulating layer, and the thin film encapsulating layer is sandwiched between the buffer layer and the display substrate.
