Abstract

A support structure for a flexible panel. The flexible panel includes a non-bending area, a bending area and a pad area arranged in sequence along a first direction. The pad area is located at a backlight side of the non-bending area. The support structure includes a support plate, and the support plate includes a planar support area attached to the non-bending area and a patterned area at least attached to the bending area. The present disclosure further provides a method for assembling a flexible module, and a display device.

First claim

What is claimed is:

1. A support structure for a flexible panel, wherein the flexible panel comprises a non-bending area, a bending area and a pad area arranged in sequence along a first direction, the pad area is located at a backlight side of the non-bending area, and the support structure comprises a support plate, wherein the support plate comprises a planar support area attached to the non-bending area and a patterned area at least attached to the bending area:
wherein the support structure is applied to a display device comprising the flexible panel, the support plate comprises a first side and a second side arranged opposite to each other in a second direction, a connection structure is arranged at each of the first side and the second side and coupled to a corresponding side of the display device, and the second direction is perpendicular to the first direction;
wherein the connection structure comprises a first connection portion located at the first side and a second connection portion located at the second side, the first connection portion is formed by bending the first side along a direction perpendicular to the support plate and bending the first side again in a direction away from the second side, and the second connection portion is formed by bending the second side along the direction perpendicular to the support plate and bending the second side again in a direction away from the first side.

2. The support structure according to claim 1 , wherein the connection structure comprises a first connection portion formed through extending the first side in a direction away from the second side and a second connection portion formed through extending the second side in a direction away from the first side.

3. The support structure according to claim 2 , wherein the first connection portion comprises a first connection sub-portion and a second connection sub-portion spaced apart from each other along the first direction, a length of the first connection sub-portion in the second direction is less than or equal to a length of the support plate in the second direction, and a length of the second connection sub-portion in the second direction is less than or equal to a bending length of the bending area, wherein the second connection portion comprises a third connection sub-portion and a fourth connection sub-portion spaced apart from each other along the first direction, the third connection sub-portion has a same structure as the first connection sub-portion, and the fourth connection sub-portion has a same structure as the second connection sub-portion.

4. The support structure according to claim 1 , wherein the patterned area is provided with a plurality of through holes arranged in an array form along the first direction.

5. The support structure according to claim 4 , wherein each through hole is a strip-shaped through hole extending along a second direction, and the second direction is perpendicular to the first direction.

6. The support structure according to claim 1 , wherein the patterned area is a flat structure located on a same plane as the planar support area, or the patterned area at least comprises a corresponding bending portion that matches a bending degree of the bending area of the flexible panel.

7. A display device, comprising a flexible panel and the support structure according to claim 1 .

8. The display device according to claim 7 , wherein the display device further comprises a frame configured to carry the flexible panel and provided with a corresponding connection structure fit to the connection structure.

9. A method for assembling a flexible module, comprising:
providing a flexible panel in a flat state and the support structure according to claim 1 , the flexible panel comprising a non-bending area, a to-be-bent area and a pad area, the planar support area and the patterned area of the support plate of the support structure being located on a same plane; and
integrally bending the to-be-bent area of the flexible panel and a portion of the support plate corresponding to the to-be-bent area so that the pad area of the flexible panel is located at a backlight side of the non-bending area.

10. A method for assembling a flexible module, comprising:
providing a flexible panel and the support structure according to claim 1 , the support plate of the support structure comprising a planar support area attached to the non-bending area and a patterned area at least attached to the bending area; and
attaching the non-bending area of the flexible panel to the planar support area of the support plate and attaching the bending area of the flexible panel to a portion of the patterned area corresponding to the bending area, so as to assemble the flexible panel with the support plate.

11. The support structure according to claim 1 , wherein the first connection portion comprises a first connection sub-portion and a second connection sub-portion spaced apart from each other along the first direction, a length of the first connection sub-portion in the second direction is less than or equal to a length of the support plate in the second direction, and a length of the second connection sub-portion in the second direction is less than or equal to a bending length of the bending area, wherein the second connection portion comprises a third connection sub-portion and a fourth connection sub-portion spaced apart from each other along the first direction, the third connection sub-portion has a same structure as the first connection sub-portion, and the fourth connection sub-portion has a same structure as the second connection sub-portion.
