A display device with wireless power supply from power transmission means is disclosed in the disclosure. The display device comprises a display module, a system controlling module and a wireless power receiving module. The system controlling module is electrically connected to the display module. The wireless power receiving module is electrically connected to the system controlling module. The wireless power receiving module comprises a plurality of near-field coil units. The near-field coil units have individual receiving frequencies and individual output powers. The near-field coil units are configured to resonate with a transmission coil of the power transmission means. According to a transmission frequency on the transmission coil, the near-field coil unit with corresponding receiving frequency generates an electricity supply with a certain output power to the system controlling module. In addition, a wireless power transmission system is also disclosed herein.

Display device and wireless power transmission system

A wireless power transmission device includes a power transmitter, a first transmission unit, a power receiver, a feedback regulator, a receive controller, and a second transmission unit. The power transmitter is for generating power, and the first transmission unit is for wirelessly transmitting power generated by the power transmitter. The power receiver is for receiving and rectifying the power from the first transmission unit. The feedback regulator is for receiving a feedback signal from the power receiver to generate an AC control signal. The receive controller is for receiving the control signal to generate a driving signal. The second transmission unit is for wirelessly transmitting the control signal to the receive controller.

Wireless power transmission device

A display with wireless power charging function, an operation method thereof and a corresponding portable electronic apparatus are provided. The display includes a RFID read/write module and is applicable to electrically charge a portable electronic apparatus with a RFID tag. The operation method includes steps of: displaying an image on the display surface of the display panel of the display; transmitting data between the Radio Frequency Identification read/write module of the display and the Radio Frequency Identification tag of the portable electronic apparatus and electrically charging the energy storage unit of the portable electronic apparatus while the portable electronic apparatus is placed in the readable/writable area; and adjusting, while the portable electronic apparatus is placed in the readable/writable area, the image to an updated image having no overlap with the readable/writable area if the image has an overlap with the readable/writable area.
