Abstract

A module structure includes a support film layer. The support film layer includes a film layer body and a stress relief gap disposed in the film layer body. The stress relief gap includes a layer gap, and the film layer body is divided into stacked sub-layers by the layer gap. In the module structure according to the embodiments of the present application, the stress relief gap is disposed in the film layer body of the support film layer.

Claims

1. A module structure, comprising a support film layer, the support film layer comprising a film layer body and a stress relief gap disposed in the film layer body, the stress relief gap comprising a layer gap, the film layer body being divided into stacked sub-layers by the layer gap.

2. The module structure of claim 1, wherein the stress relief gap further comprises at least one linear gap disposed in at least one of the sub-layers of the film layer body.

3. The module structure of claim 2, wherein the linear gap comprises one or a combination of a strip gap, a curved gap and a fold linear gap.

4. The module structure of claim 3, wherein the strip gap is disposed along a direction parallel to an extension direction of the sub-layers and extends through both ends of at least one of the sub-layers in the extension direction of the sub-layers.

5. The module structure of claim 4, wherein at least one of the sub-layers comprises a plurality of strip gaps arranged at intervals, and the plurality of strip gaps are located in a same straight line.

6. The module structure of claim 4, wherein at least one of the sub-layers comprises a plurality of strip gaps arranged at intervals, and in a same sub-layer, spacing between adjacent strip gaps in a longitudinal direction is from 1 mm to 40 mm.

7. The module structure of claim 1, wherein each sub-layer comprises a bending area and a non-bending area, and the stress relief gap further comprises a hole-shaped gap disposed in the bending area of at least one of the sub-layers.

8. The modular structure of claim 7, wherein the hole-shaped gap is a circular hole.

9. The modular structure of claim 8, wherein a diameter of the circular hole is from 30 mm to 300 mm.

10. The module structure of claim 7, wherein the stress relief gap further comprises a hole-shaped gap disposed in the non-bending area of at least one of the sub-layers, an aperture of the hole-shaped gap in the bending area is consistent with an aperture of the hole-shaped gap in the non-bending area, and a density of the hole-shaped gap in the bending area is greater than a density of the hole-shaped gap in the non-bending area.

11. The module structure of claim 10, wherein the hole-shaped gap disposed in the non-bending area is a blind hole.

12. The module structure of claim 7, wherein the stress relief gap further comprises a hole-shaped gap disposed in the non-bending area of at least one of the sub-layers, a density of the hole-shaped gap in the bending area is consistent with a density of the hole-shaped gap in the non-bending area, and an aperture of the hole-shaped gap in the bending area is larger than an aperture of the hole-shaped gap in the non-bending area.

13. The module structure of claim 12, wherein the hole-shaped gap disposed in the non-bending area is a blind hole.

14. The module structure of claim 7, wherein the hole-shaped gap disposed in the bending area is a blind hole.

15. A flexible display device, comprising the module structure according to claim 1.
