Electronic device and its operation system
View Patent ↗An electronic device earned around by the user is desired to be used for a long period. In order to achieve this, a high-capacity battery may be incorporated. Since a high-capacity battery is large, its incorporation in an electronic device increases the weight of the electronic device. An electronic device used while being implanted in the body of the user, provided with an emergency power supply, is provided, in an electronic device provided with a plurality of batteries, a transmitting portion and a receiving portion conduct wireless charging among different batteries, and the battery to be charged or used is selected by a power supply management circuit depending on the circumstances.
1. An electronic device comprising:
a display module comprising a display portion and a display driver circuit;
a communication module comprising a communication circuit;
a first wireless receiving portion;
a second wireless receiving portion; and
a battery configured to be charged from an external source through at least one of the first wireless receiving portion and the second wireless receiving portion,
wherein the display portion includes a transistor including an oxide semiconductor in a channel formation region,
wherein each of the display module and the communication module is configured to be able to be turned on or turned off independently.
2. The electronic device according to claim 1 , wherein the electronic device is flexible.
3. The electronic device according to claim 1 , wherein the transistor is a double-gate type.
4. The electronic device according to claim 1 , wherein at least one of the first wireless receiving portion and the second wireless receiving portion includes an antenna.
5. The electronic device according to claim 1 , wherein the electronic device is a mobile computer.
6. An electronic device comprising:
a display module comprising a display portion and a display driver circuit;
a communication module comprising a communication circuit;
a control module comprising a CPU;
a first wireless receiving portion;
a second wireless receiving portion; and
a battery configured to be charged from an external source through at least one of the first wireless receiving portion and the second wireless receiving portion,
wherein the display portion includes a transistor including an oxide semiconductor in a channel formation region,
wherein each of the display module and the communication module is configured to be able to be turned on or turned off independently.
7. The electronic device according to claim 6 , wherein the electronic device is flexible.
8. The electronic device according to claim 6 , wherein the transistor is a double-gate type.
9. The electronic device according to claim 6 , wherein at least one of the first wireless receiving portion and the second wireless receiving portion includes an antenna.
