Problems solved by technology
[0003] For electrical equipment that is placed close to a fixed location and placed stably for a long time, it consumes a lot of power and requires a high-power wireless power supply equipment, which will inevitably result in a large space occupation and strong electromagnetic radiation, which cannot meet the requirements Such as the wireless power supply needs of DC power display devices such as TVs and monitors
[0004] For display devices including televisions and monitors, their installation positions are relatively fixed for a long time, and the layout of their power lines will cause problems such as indoor wiring, wall renovation, and landscape damage. The wireless power supply scheme provided can greatly solve this problem

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.
Description
technical field [0001] The invention belongs to the technical field of power supply of a display device, and in particular relates to a power supply method of a display device which is convenient for installation and placement of the display device and a display device with wireless power supply. Background technique [0002] The development of wireless power supply technology has gradually made wireless power-consuming equipment a commercial model and has been further developed. However, for most power-consuming equipment, the wireless charging technology required is relatively harsh. For example, in the prior art, various portable electronic devices capable of real-line wireless power supply have been proposed as conceptual products, but the wireless power supply technology on which it is based must support portable electronic devices such as mobile phones, notebook computers, and MIDs to obtain relatively stable and continuous wireless power. However, the existing wirele...
