Abstract

A light-emitting device can be folded in such a manner that a flexible light-emitting panel is supported by a plurality of housings which are provided spaced from each other and the light-emitting panel is bent so that surfaces of adjacent housings are in contact with each other. Furthermore, in the light-emitting device, in which part or the whole of the housings have magnetism, the two adjacent housings can be fixed to each other by a magnetic force when the light-emitting device is used in a folded state.

Claims (74)

1. An electronic device comprising:

a light-emitting panel;

a first protection fixed to a back of the light-emitting panel;

a first housing overlapping with a first region of the light-emitting panel; and

a second housing overlapping with a second region of the light-emitting panel,

wherein the first housing is less flexible than the light-emitting panel, and

wherein the second housing is less flexible than the light-emitting panel.

2. The electronic device according to claim 1 , further comprising a sensor configured to determine whether the electronic device is in a folded state or not.

3. The electronic device according to claim 1 , further comprising:

a bending portion provided between the first housing and the second housing;

a second protection provided between the first housing and the second housing; and

a plurality of magnets,

wherein the second protection is exposed between the first housing and the second housing,

wherein the light-emitting panel and the first protection have a region overlapping with the bending portion,

wherein the first protection overlaps with the first housing and the second housing,

wherein the first protection is configured to be bent in the bending portion,

wherein the electronic device is configured to be foldable by bending the bending portion,

wherein the light-emitting panel is provided continuously from the first region of the light-emitting panel to the second region of the light-emitting panel,

wherein the first region of the light-emitting panel and the second region of the light-emitting panel overlap with and face each other, in a folded state of the electronic device,

wherein, in an opened state of the electronic device, an image is displayed in the first region, the second region, and the region where the light-emitting panel overlaps with the bending portion,

wherein, in the folded state of the electronic device, neither of the first region of the light-emitting panel, the second region of the light-emitting panel, and the region where the light-emitting panel overlaps with the bending portion are visible,

wherein the electronic device is configured to be fixed in the folded state via the plurality of magnets,

wherein the light-emitting panel comprises a transistor comprising an oxide semiconductor layer,

wherein the oxide semiconductor layer comprises a channel formation region, and

wherein the transistor is electrically connected to a light-emitting element.

4. An electronic device comprising:

a light-emitting panel;

a first protection fixed to a back of the light-emitting panel;

a first housing overlapping with a first region of the light-emitting panel;

a second housing overlapping with a second region of the light-emitting panel;

a third housing surrounding a first side of the light-emitting panel, a first region of a second side of the light-emitting panel, and a first region of a third side of the light-emitting panel;

a fourth housing surrounding a fourth side of the light-emitting panel, a second region of the second side of the light-emitting panel, and a second region of the third side of the light-emitting panel;

a second protection provided between the third housing and the fourth housing;

a bending portion provided between the first housing and the second housing; and

a plurality of magnets,

wherein the first housing is less flexible than the light-emitting panel,

wherein the second housing is less flexible than the light-emitting panel,

wherein the second protection is exposed between the third housing and the fourth housing,

wherein the second protection overlaps with the third housing and the fourth housing,

wherein the light-emitting panel and the first protection have a region overlapping with the bending portion,

wherein the electronic device is configured to be foldable by bending the bending portion,

wherein the light-emitting panel is provided continuously from the first region of the light-emitting panel to the second region of the light-emitting panel,

wherein the first region of the light-emitting panel and the second region of the light-emitting panel overlap with and face each other, in a folded state of the electronic device,

wherein, in an opened state of the electronic device, an image is displayed in the first region of the light-emitting panel, the second region of the light-emitting panel, and the region where the light-emitting panel overlaps with the bending portion,

wherein the electronic device is configured to be fixed in the folded state via the plurality of magnets,

wherein the light-emitting panel comprises a transistor comprising an oxide semiconductor layer, and

wherein the oxide semiconductor layer comprises a channel formation region.

5. The electronic device according to claim 4 , further comprising a sensor configured to determine whether the electronic device is in the folded state or the opened state.

6. An electronic device comprising:

a light-emitting panel;

a first protection fixed to a back of the light-emitting panel;

a first housing overlapping with a first region of the light-emitting panel;

a second housing overlapping with a second region of the light-emitting panel;

a third housing overlapping with the first housing with the first protection and the light-emitting panel therebetween;
