In order to illustrate the technical means in the embodiments of the present disclosure more clearly, the accompanying drawings that need to be used in the description of the embodiments are briefly described below. It is obvious that the accompanying drawings in the following description are merely some embodiments of the present disclosure, and those skilled in the art may obtain other drawings according to these drawings without involving creative effort.
The wireless projection system of the relevant art comprises a transmitter and a receiver, wherein the transmitter is connected to the signal source device, and the receiver is connected to the display device. The signal source device sends a display signal generated by the signal source device to the display device through the transmitter and the receiver sequentially, and the display device receives the display signal and displays the display signal.

There is a need for additional hardware, such as a button or a USB interface when pairing. Wherein, the pre-pairing generally adopts USB pairing, and specifically, the transmitter and the receiver are paired in series through a USB or a USB portable disk is used to store a pairing file, and then pairing is performed respectively. The pairing manner causes the need of a USB serial connection in each of the transmitters and each of the receivers for pairing. Meanwhile, it causes operation complexity during use and the user experience is poor.
Therefore, it is necessary to provide a new method to solve the above technical problem.
The technical means in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present disclosure, and it is clear that the described embodiments are only some, not all, embodiments of the present disclosure. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

Wherein, the communication connection is a wireless connection.
In this embodiment, the communication connection includes a WIFI connection, an Ethernet connection, and a Bluetooth connection.
It should be noted that the display device 1, the signal source device 2, the transmitter 3, and the receiver 4 are all common devices, modules, or components in the art. A designer selects a related model according to actual needs, which is not described in detail herein.
The transmitter 3 includes a first image channel 31, a first identification data channel 32, and a first communication module 33.
The first image channel 31 is in data connection with the signal source device 2. The first image channel 31 is used to receive the display signal output by the signal source device 2.
The first identification data channel 32 is used to send data to the receiver 4.
The first communication module 33 is used to be in communication connection with the second communication module 43.
The receiver 4 includes a second image channel 41, a second identification data channel 42, and a second communication module 43.
The second image channel 41 is in data connection with the display device 1 and can be in data connection with the first image channel 31. The second image channel 41 is used to output an image to the display device 1.
The second identification data channel 42 is used to receive data sent by the first identification data channel 32.
