1. A wireless power transmitter, comprising:
a first resonator including at least one coil;
a second resonator including at least one coil;
at least one light emitting device comprising light-emitting circuitry; at
least one phase shifter comprising phase shifting circuitry; memory
storing instructions; and
at least one processor,
wherein the instructions, when executed by the at least one processor, cause the wireless power transmitter to:
control the at least one light emitting device to display a first wirelessly chargeable area on a plane where an electronic device is placed;
control the wireless power transmitter to receive a signal for changing the first wirelessly chargeable area on the plane where the electronic device is placed; and
in response to receiving the signal for changing the first wirelessly chargeable area, control the at least one light emitting device to display a second wirelessly chargeable area changed from the first wirelessly chargeable area, on the plane where the electronic device is placed,
wherein the at least one phase shifter supplies phase-shifted power to the first resonator or the second resonator to output wireless power in a direction corresponding to the second wirelessly chargeable area,
wherein as the at least one light emitting device moves downward in an orthogonal direction to the plane where the electronic device is placed, the first wirelessly chargeable area boundaries are changed such that an arc length of the first wireless chargeable area decreases as the radius from the central axis of the wireless power transmitter to the arc length of the first wirelessly chargeable area increases.
