Abstract

A flexible laminated structure includes a first protective layer, a plurality of patterned structures, and a second protective layer. The patterned structures are disposed on the first protective layer and expose a portion of the first protective layer. Each of the patterned structures has a first width adjacent to the first protective layer and a second width away from the first protective layer, and the first width is smaller than the second width. The second protective layer is disposed on the first protective layer and covers the patterned structures and the first protective layer.

Claims

1. A flexible laminated protective structure externally disposed on a flexible display unit, comprising:

a first protective layer disposed on the flexible display unit;

a plurality of patterned structures, directly disposed on the first protective layer and exposing a portion of the first protective layer, wherein each of the plurality of patterned structures has a first width adjacent to the first protective layer and a second width away from the first protective layer, the first width is smaller than the second width; and

a second protective layer, directly disposed on the plurality of patterned structures and the first protective layer, wherein the attachment of the second protective layer to the first protective layer is increased by the plurality of patterned structures, and

wherein each of the patterned structures comprises a first pattern structure and a second pattern structure, the first pattern structure is located between the second pattern structure and the first protective layer, the first pattern structure has the first width, and the second pattern structure has the second width, and a material of the first patterned structure is different from a material of the second patterned structure.

2. The flexible laminated structure as recited in claim 1, wherein a material of the first pattern structure is a silicon oxide, and a material of the second pattern structure is a silicon nitride.

3. The flexible laminated structure as recited in claim 1, wherein a material of each of the patterned structures is a silicon oxynitride, and an oxygen content of the silicon oxynitride gradually reduces from a side adjacent to the first protective layer to another side away from the first protective layer.

4. The flexible laminated structure as recited in claim 1, wherein a material of each of the patterned structures is a silicon oxynitride, and a nitrogen content of the silicon oxynitride gradually reduces from a side adjacent to the first protective layer to another side away from the first protective layer.

5. A display, comprising:

a flexible display unit; and

a flexible laminated protective structure, externally disposed on the flexible display unit, the flexible laminated structure comprising;

a first protective layer disposed on a flexible display unit;

a plurality of patterned structures, directly disposed on the first protective layer and exposing a portion of the first protective layer, wherein each of the plurality of patterned structures has a first width adjacent to the first protective layer and a second width away from the first protective layer, the first width is smaller than the second width; and

a second protective layer, directly disposed on the plurality of patterned structures and the first protective layer, wherein the attachment of the second protective layer to the first protective layer is increased by the plurality of patterned structures, and

wherein each of the patterned structures comprises a first pattern structure and a second pattern structure, the first pattern structure is located between the second pattern structure and the first protective layer, the first pattern structure has the first width, and the second pattern structure has the second width, and a material of the first patterned structure is different from a material of the second patterned structure.

6. The display as recited in claim 5, wherein a material of the first pattern structure is a silicon oxide, and a material of the second pattern structure is a silicon nitride.

7. The display as recited in claim 5, wherein a material of each of the patterned structures is a silicon oxynitride, and an oxygen content of the silicon oxynitride gradually reduces from a side adjacent to the first protective layer to another side away from the first protective layer.

8. The display as recited in claim 5, wherein a material of each of the patterned structures is a silicon oxynitride, and a nitrogen content of the silicon oxynitride gradually reduces from a side adjacent to the first protective layer to another side away from the first protective layer.

9. The display as recited in claim 5, wherein the flexible display unit is an electrophoretic display panel.
