Abstract
A touch screen, an electronic device, a wireless charging method and a wireless charging system are provided, to overcome the defect in the conventional technology that an additional wireless charging device needs to be provided for an electronic device to wirelessly charging the electronic device. The touch screen is applied to the electronic device, and includes a touch sensor and a touch chip, where the touch sensor is electrically connected to the touch chip. In a case that the touch screen is used for wireless charging, the touch chip controls the touch sensor to form a receiving coil or a transmitting coil.
Claims20
A touch screen applied to an electronic device, comprising:
- a touch sensor;
- and
- a touch chip electrically connected to the touch sensor, and configured to control the touch sensor to form a receiving coil or a transmitting coil if the touch screen is used for wireless charging, wherein
- in a case that the touch sensor comprises first conducting electrodes and second conducting electrodes, the first conducting electrodes and the second conducting electrodes are arranged across each other at a predetermined angle, and the predetermined angle is an acute angle or a right angle,
- the touch chip being configured to control the touch sensor to form the receiving coil comprises the touch chip being configured to control the first conducting electrodes to form a first receiving coil, and/or control the second conducting electrodes to form a second receiving coil, and
- the touch chip being configured to control the touch sensor to form the transmitting coil comprises the touch chip being configured to control the first conducting electrodes to form a first transmitting coil, and/or control the second conducting electrodes to form a second transmitting coil, and
- in a case that the touch sensor comprises self-capacitive conducting electrodes,
- the touch chip being configured to control the touch sensor to form the receiving coil comprises the touch chip being configured to control the self-capacitive conducting electrodes to form a receiving coil, and
- the touch chip being configured to control the touch sensor to form the transmitting coil comprises the touch chip being configured to control the self-capacitive conducting electrodes to form a transmitting coil.
