Abstract
A foldable display device assembly includes a rigid film having first and second sections spaced apart from each other, the rigid film being foldable about a folding axis disposed between the first and second sections of the rigid film; an adhesion structure having first and second adhesion sections spaced apart from each other, the first and second adhesion sections being disposed on the first and second sections of the rigid film, respectively; a lower flexible module disposed on the adhesion structure; a flexible display module disposed on the lower flexible module; and an upper flexible module disposed on the flexible display module.
Claims29
A foldable display device assembly, comprising:
- a rigid film having first and second sections spaced apart from each other, the rigid film being foldable about a folding axis disposed between the first and second sections of the rigid film;
- an adhesion structure having first and second adhesion sections spaced apart from each other, the first and second adhesion sections being disposed on the first and second sections of the rigid film, respectively;
- a lower flexible module disposed on the adhesion structure;
- a flexible display module disposed on the lower flexible module;
- and
- an upper flexible module disposed on the flexible display module,
- wherein at least a portion of a lower surface of the first adhesion section corresponds to a first lower adhesion region to which an upper surface of the first section of the rigid film is adhered, at least a portion of an upper surface of the first adhesion section corresponds to a first upper adhesion region to which a lower surface of the lower flexible module is adhered, and an is area of the first lower adhesion region is substantially different from an area of the first upper adhesion region,
- wherein at least a portion of a lower surface of the second adhesion section corresponds to a second lower adhesion region to which an upper surface of the second section of the rigid film is adhered, at least a portion of an upper surface of the second adhesion section corresponds to a second upper adhesion region to which a lower surface of the lower flexible module is adhered, and an area of the second lower adhesion region is substantially different from an area of the second upper adhesion region.

A foldable display device assembly, comprising:
- a plate having a first section, a second section, and a connection section connected between the first and second sections, the plate being foldable about a folding axis disposed between the first and second sections, the first and second sections being rigid or semi-rigid, the connection section having a foldability and a first width measured in a direction from the first section of the plate to the second section of the plate when the foldable display device assembly is unfolded;
- a lower flexible module disposed on the plate;
- a first double-sided adhesive film disposed on the lower flexible module;
- a flexible display module disposed on the first double-sided adhesive film, the flexible display module having an electroluminescent unit;
- a second double-sided adhesive film disposed on the flexible display module;
- and
- an upper flexible module disposed on the second double-sided adhesive film,
- wherein the connection section of the plate has an average thickness substantially smaller than the first and second sections of the plate, and
- the lower flexible module has a substantially lower light transmittance than the upper flexible module.

A foldable display device assembly, comprising:
- a rigid film having first and second sections between which a space having a width measured in a direction from the first section of the rigid film to the second section of the rigid film when the foldable display device assembly is unfolded is disposed, the rigid film being foldable about a folding axis disposed between the first and second sections;
- a buffer film disposed on the rigid film;
- a first double-sided adhesive film disposed on the buffer film;
- a lower flexible module disposed on the first double-sided adhesive film;
- a second double-sided adhesive film disposed on the lower flexible module;
- a flexible display module disposed on the second double-sided adhesive film, the flexible display module having an electroluminescent unit;
- a third double-sided adhesive film disposed on the flexible display module;
- and
- an upper flexible module disposed on the third double-sided adhesive film,
- wherein the lower flexible module has a substantially lower light transmittance than the upper flexible module, and
- the buffer film prevents an adhesion between the rigid film and the first double-sided adhesive film from decreasing due to a difference in a physical property between the rigid film and the first double-sided adhesive film.
