Abstract
The present application provides a foldable display device, a manufacturing method thereof, and a jig. The foldable display device includes a folding region, a non-folding region, a flexible display panel, and a functional layer attached through an adhesive layer. In a pre-bent state of the foldable display device, an angle between portions of the foldable display device corresponding to the non-folding region on two opposite sides of the folding region is greater than 0 degree and less than 180 degrees. A stress of a portion of the adhesive layer corresponding to the folding region is less than or equal to a first predetermined threshold.
Claims11
A foldable display device, comprising:
- a folding region;
- a non-folding region disposed on two opposite sides of the folding region;
- a flexible display panel;
- and
- at least one functional layer attached to the flexible display panel through an adhesive layer;
- wherein the foldable display device comprises a pre-bent state, a flattened state, and a fully folded state;
- wherein in the pre-bent state, an angle between portions of the foldable display device corresponding to the non-folding region on two opposite sides of the folding region is greater than 0 degree and less than 180 degrees, and a stress of a portion of the adhesive layer corresponding to the folding region is less than or equal to a first predetermined threshold;
- and
- wherein when the foldable display device is in the pre-bent state, there is no misalignment between the flexible display panel and the at least one functional layer;
- and
- when the foldable display device is in the flattened state and the fully folded state, the flexible display panel and the at least one functional layer are misaligned.
