Abstract

An electronic device having a novel structure is provided. A battery is provided in each component of an electronic device, whereby the electronic device includes two batteries. The electronic device including the two batteries and a display portion that can be called a flexible display and has a plurality of foldable portions is provided as a novel device.

First claim

The invention claimed is:

1. An electronic device comprising:
a central processing unit;
a display portion;
a touch input portion; and
a power management circuit,
wherein the display portion is bendable and includes a first region, a second region, and a third region,
wherein the first region overlaps with the central processing unit,
wherein the second region overlaps with a first battery in a state where the display portion is unfolded,
wherein the third region overlaps with a second battery in the state where the display portion is unfolded, and
wherein the first battery has a region not overlapping with the second battery in a state where the display portion is folded.

2. The electronic device according to claim 1 , wherein the touch input portion includes a transistor including an oxide semiconductor layer.

3. The electronic device according to claim 1 , wherein the central processing unit is electrically connected to the first battery and the display portion is electrically connected to the second battery.

4. The electronic device according to claim 1 , wherein the power management circuit has a function of wirelessly transmitting power of the first battery to the second battery.

5. The electronic device according to claim 1 , wherein a first bendable portion is provided between the first region and the second region and a second bendable portion is provided between the second region and the third region.

6. An electronic device comprising:
a central processing unit;
a display portion;
a touch input portion; and
a power management circuit,
wherein the display portion is bendable and includes a first region, a second region, and a third region,
wherein the first region overlaps with the central processing unit,
wherein the second region overlaps with a first battery in a state where the display portion is unfolded,
wherein the third region overlaps with a second battery in the state where the display portion is unfolded, and
wherein the first battery overlaps with the second battery in a state where the display portion is folded.

7. The electronic device according to claim 6 , wherein the touch input portion includes a transistor including an oxide semiconductor layer.

8. The electronic device according to claim 6 , wherein the central processing unit is electrically connected to the first battery and the display portion is electrically connected to the second battery.

9. The electronic device according to claim 6 , wherein the power management circuit has a function of wirelessly transmitting power of the first battery to the second battery.

10. The electronic device according to claim 6 , wherein a first bendable portion is provided between the first region and the second region and a second bendable portion is provided between the second region and the third region.

11. An electronic device comprising:
a central processing unit including a first battery, a first receiving portion, and a first transmitting portion;
a display portion including a second battery, a second receiving portion, and a second transmitting portion;
a touch input portion; and
a power management circuit,
wherein the first receiving portion has a function of wirelessly charging the first battery,
wherein the second receiving portion has a function of wirelessly charging the second battery,
wherein the touch input portion is electrically connected to the second battery, and
wherein the power management circuit has a function of wirelessly transmitting power of the first battery to the second battery.

12. The electronic device according to claim 11 , wherein the first battery is electrically connected to the first receiving portion through a first regulator.

13. The electronic device according to claim 11 , wherein the second battery is electrically connected to the second receiving portion through a second regulator.

14. The electronic device according to claim 11 , wherein the display portion overlaps with the first battery and the second battery.

15. The electronic device according to claim 11 , wherein the display portion includes a plurality of bendable portions.

16. The electronic device according to claim 11 , wherein the touch input portion includes a transistor including an oxide semiconductor layer.
