A wireless screen sharing device that magnetically connects the transmitting end and the receiving end

Abstract

The present invention relates to the technical field of wireless co-screening, and discloses a wireless co-screening device magnetically connected to a transmitting end and a receiving end, including a wireless co-screening device HUB, and the HUB includes: a receiving end RT, on which a receiving end RT is equipped with NFC near-field communication module I, and a magnet module I is installed on the receiving end RT; also includes: a transmitting end TT, on which an NFC near-field communication module II is mounted on the transmitting end TT, and a magnet is installed on the transmitting end TT Module II; before the data exchange between the transmitting end TT and the receiving end RT, the NFC near field communication module II at the transmitting end begins to send data to the NFC near field communication module I at the receiving end only after the identity of the NFC near field communication module I at the receiving end is proved to be legal. The same screen data on the signal transmitting device STE; the transmitting terminal TT realizes non-fixed contact connection with the receiving terminal RT through magnetic attraction. The invention solves the problem of how to ensure the safe and stable signal transmission of the wireless screen sharing device.

Description

technical field [0001] The invention relates to the technical field of wireless co-screening, in particular to a wireless co-screening device magnetically connecting a transmitting end and a receiving end. Background technique [0002] The screen sharer is to push pictures, videos and music on mobile phones, tablets and computers to display screens, TVs, projectors, etc., to realize the transmission of digital multimedia (high-definition video, audio, pictures) content, and to synchronize different screens The displayed content makes the small screen bigger. Compatible and spanning operations are realized between different operating systems (IOS, ANDROID, WIN7, WINDOWS XP, VISTA, etc.) and different terminal devices (mobile phones, tablets, computers, TVs). The same screen device breaks the disadvantages of independent operation and inability to interact with each platform device, and can realize more free office and life. [0003] At present, the screen sharer can be divi...

Problems solved by technology

[0003] At present, the screen sharer can be divided into wired screen sharer and wireless screen sharer. The main difference between the wired screen sharer and the wireless screen sharer is that it is connected with it. Connect one end to a mobile phone and the other end to a TV and other devices to achieve the same screen. Although the advantage of the wired screen sharer is that the transmission is stable and not affected by the power, the disadvantage of the wired screen sharer is that it is bound by cables.

[0004] In contrast, the connection method of the wireless co-screen is more convenient and intelligent. The wireless co-screen is projected to TV and other devices through WiFi to realize cross-platform co-screen display. Its advantages are: not bound by cables, You can move freely; but its disadvantage is: sometimes the transmission signal will be unstable
