Abstract
A foldable display apparatus includes a mid-layer having a hinge region; a panel on the mid-layer; a pair of set frames under the mid-layer; and a hinge portion connected to the pair of set frames, and moving as the panel is folded or unfolded. Since a sliding section of the panel in the hinge region is compensated for during the folding and unfolding of the panel, the size of a bezel that would otherwise accommodate a sliding section can be reduced.
Claims18
A foldable display apparatus, comprising:
- at least two set frames each having a curved portion corresponding to where the foldable display apparatus folds;
- between each set frame, a support member having at least one pair of links, each of the at least one pair of links having one portion hinged along a second axis disposed on opposite sides of the support member and another portion hinged along a first axis disposed on a curved portion of an adjacent set frame, wherein each of the pair of set frames is configured to rotate around the first axis, each of the at least one pair of links is configured to rotate around the second axis, and the support member is configured to move back and forth relative to the curved portions of each of the at least two set frames;
- a mid-layer disposed along an outer surface of the pair of set frames;
- and
- a panel along an outer surface of the mid-layer.
2 more elements
A device, comprising:
- a panel;
- a mid-layer attached to the panel;
- at least a pair of set frames on which the mid-frame is attached;
- and
- a compensation area disposed between each set frame, each compensation area expanding and contracting a space between each set frame as the foldable device transitions between a folded and unfolded state.
2 more elements
A folding apparatus, comprising:
- a pair of set frames facing each other when the folding apparatus is in an unfolded state;
- a pair of joints, of which one joint includes a second portion connected to one in the pair of set frames and the other joint includes a second portion connected to the other in the pair of set frames;
- a support member, wherein a first portion of each of the joints is connected to opposite sides of the support member;
- and
- a flexible layer on the folding apparatus, such that it folds and unfolds along with the folding apparatus;
- and
- wherein a distance between the set frames is greater when the folding apparatus is in the unfolded state than when the folding apparatus is in the folded state, and the support member moves with a rotation of the pair of joints to compensate for a change in the distance between the pair of set frames.
