Stereo glasses wireless power supply system

Abstract

The invention provides a wireless power supply system of a pair of stereo glasses, comprising an energy emission device and an energy receiving device, wherein the energy emission device and the energy receiving device are arranged in the stereo glasses in a physical separation manner, wherein the energy emission device is used for transmitting energy through electromagnetic waves, and the energyreceiving device is used for receiving the electromagnetic waves emitted by the energy emission device and converting the energy carried by the electromagnetic waves into a direct current voltage required by the stereo glasses. The wireless power supply system of the stereo glasses applies an electromagnetic resonance principle and comprises the energy emission device and the energy receiving device, wherein the energy emission device is arranged on stereo display equipment, the energy receiving device is arranged on the stereo glasses, the energy emission device and the energy receiving device are physically separated, the energy receiving device is used for receiving the energy carried by the electromagnetic waves emitted by the energy emission device and converting the direct current voltage required by the stereo glasses for related circuits, and therefore the problem that the stereo glasses need to replace batteries or are charged is solved; in addition, a field synchronizing signal can be transmitted to the stereo glasses through the transmission of the electromagnetic waves.

Description

technical field [0001] The invention relates to power supply technology, in particular to a wireless power supply system for stereo glasses. Background technique [0002] Color TV has gone through a glorious road of technological innovation from CRT to flat-panel TV. Now consumers have higher and higher requirements, and the display format of TV content and color TV is also developing from 2D to 3D to meet the needs of consumers. [0003] The principle of 3D imaging is to make the content seen by the left and right eyes different, so that the two eyes have parallax, and a three-dimensional illusion will be formed in the human brain due to parallax. At present, there are many ways to realize 3D TV, among which the most mature and effective way is stereo glasses using liquid crystal electronic light valve, which is equipped with a synchronous transmitting and receiving device, and the TV displays the left eye and right eye according to certain rules. The receiving device rece...

Problems solved by technology

[0004] The three-dimensional glasses of this imaging method are active, so independent power supply is required. Generally, the power supply method of button batteries is adopted. The power supply time is short and the battery needs to be replaced frequently, making it expensive to use, inconvenient to use at any time, and not conducive to environmental protection. At the same time, the synchronization signal of the stereo glasses is transmitted in the form of infrared light, which will also interfere with the infrared remote control reception of the TV itself.
