    摘要: A radio frequency (RF) charging system is capable of charging an RF device on a display panel to increase charging efficiency. The RF device generates a response signal upon receiving an RF signal. The RF charging system includes an antenna set having a plurality of antennas, a switch unit, an RF module and a microcontroller unit (MCU). The MCU controls the switch unit to select one antenna from the antenna set. The antenna is able to receive the response signal and is used for transmitting the RF signal, thereby charging the RF device.
