Power supply method for display device and display device with wireless power

The invention discloses a power supply method for a display device and the display device with wireless power. The power supply method comprises the following steps of: converting alternating current commercial power into a high-frequency alternating current and connecting the high-frequency alternating current into an induction coil A; changing the high-frequency alternating current generated in another induction coil B arranged oppositely into a direct current by rectifying; and connecting the direct current into a power supply module loop of the display device for providing working power. The display device with the wireless power has a reasonable design, can realize high-efficiency wireless power supply of the display device including a television and a display, realizes harmless and high-efficiency wireless electric energy transmission based on current situations of a prior wireless charging technology, can effectively simplify fixed wiring of household electric appliances and indoor transformation installation, ensures the wireless power supply electromagnetic radiation safety of human bodies, and supports the wireless power supply commercial operation of the display device including the television.
