Abstract

The present disclosure provides a curved display panel. The curved display panel includes two substrates each having a first curvature, each of the two substrates including two first side regions with the first curvature and two second side regions; a sealant for bonding the two substrates together, the sealant having a first sealant portion configured to seal the first side regions and a second sealant portion configured to seal the second side regions, wherein a Young's modulus of the first sealant is less than a Young's modulus of the second sealant.

First claim

What is claimed is:

1. A curved display panel, comprising:
two substrates each having a first curvature, each of the two substrates including two first side regions with the first curvature, and two second side regions; and
a sealant structure for bonding the two substrates together, the sealant structure including a first sealant configured to seal the first side regions, and a second sealant configured to seal the second side regions,
wherein:
a Young's modulus of the first sealant is less than a Young's modulus of the second sealant, and
a ratio of the Young's modulus of the second sealant to the Young's modulus of the first sealant is between 1 and 100.

2. The curved display panel according to claim 1 , wherein two ends of each one of the second side regions are connected to the two first side regions such that the two first side regions and the two second regions form a closed structure.

3. The curved display panel according to claim 1 , wherein:
the Young's modulus of the first sealant is less than or equal to 1.6 Gpa.

4. The curved display panel according to claim 3 , wherein:
the Young's modulus of the first sealant is more than or equal to 0.016 Gpa and less than or equal to 0.16 Gpa.

5. The curved display panel according to claim 1 , wherein:
the Young's modulus of the second sealant is about 1 to 10 Gpa.

6. The curved display panel according to claim 1 , wherein:
a ratio of the Young's modulus of the second sealant to the Young's modulus of the first sealant is between 1 and 10.

7. The curved display panel according to claim 1 , wherein:
the two substrates include an array substrate and a color filter substrate; and
a liquid crystal layer is formed between the array substrate and the color filter substrate.

8. The curved display panel according to claim 7 , wherein:
the array substrate includes one or more pixel electrodes and one or more common electrodes; and
an electrical field formed by the pixel electrodes and the common electrodes is configured to control orientations of liquid crystal molecules in the liquid crystal layer.

9. The curved display panel according to claim 8 , wherein the pixel electrodes and the common electrodes have strip shapes and are arranged in an alternating manner in a same layer.

10. The curved display panel according to claim 8 , wherein:
the common electrodes are arranged opposed to the pixel electrodes; and
the common electrodes are arranged on a common electrode plane and the pixel electrodes are distributed in parallel on the common electrode plane, two adjacent pixel electrodes being separated by a portion of the common electrode plane.

11. The curved display panel according to claim 8 , wherein:
the common electrodes are arranged opposed to the pixel electrodes; and
the pixel electrodes are arranged as a pixel electrode plane and the common electrodes are distributed in parallel on the pixel electrode plane, two adjacent common electrodes being separated by a portion of the pixel electrode plane.

12. A display apparatus, including the curved display panel according to claim 1 .

13. A curved display panel according to claim 1 , further comprising a liquid crystal layer interposed between the two substrates, wherein:
a portion of the first sealant is arranged over a surface of one of the two substrates that is distant from the liquid crystal layer, and
another portion of the first sealant is arranged over a surface of the other one of the two substrates that is distant from the liquid crystal layer.
