Abstract

A highly convenient electronic device used while being worn on a body is provided. The electronic device is an arm-worn electronic device including a display panel, a power storage device, a circuit, and a sealing structure. The display panel displays an image with power supplied from the power storage device. The circuit includes an antenna and charges the power storage device wirelessly. Inside the sealing structure, the display panel, the power storage device, and the circuit are provided. The sealing structure includes a portion that transmits visible light. The sealing structure can be worn on an arm or is connected to a structure body that can be worn on an arm.

First claim

What is claimed is:

1. An electronic device comprising:
a display panel;
a power storage device;
a circuit;
a sealing structure comprising a first film and a second film; and
a structure body,
wherein the display panel includes a light-emitting element,
wherein the light-emitting element is configured to emit light with power supplied from the power storage device,
wherein the circuit includes an antenna and is configured to charge the power storage device wirelessly,
wherein the sealing structure is connected to the structure body,
wherein the first film and the second film overlap with the structure body,
wherein the display panel, the power storage device, and the circuit are sealed by the first film and the second film,
wherein at least part of the sealing structure is configured to transmit light emitted from the light-emitting element, and
wherein the structure body is capable of being worn on an arm.

2. The electronic device according to claim 1 ,
wherein the power storage device, the antenna, and the display panel are stacked in this order from an arm side when the structure body is worn on the arm.

3. The electronic device according to claim 1 , further comprising an audio input portion.

4. The electronic device according to claim 1 , further comprising a touch sensor.

5. The electronic device according to claim 1 , further comprising a member which enables the electronic device to be worn on an arm.

6. The electronic device according to claim 1 ,
wherein the display panel has a curved surface whose radius of curvature is larger than or equal to 1 mm and smaller than or equal to 150 mm, and
wherein the power storage device has a curved surface whose radius of curvature is larger than or equal to 10 mm and smaller than or equal to 150 mm.

7. The electronic device according to claim 1 ,
wherein the display panel includes a flexible portion.

8. The electronic device according to claim 1 ,
wherein the power storage device includes a flexible portion.

9. The electronic device according to claim 1 ,
wherein an inside of the sealing structure is a reduced pressure atmosphere.

10. The electronic device according to claim 1 ,
wherein a buoyancy material is inside the sealing structure.
