Wireless communications pairing method and Wireless communications pairing system

A wireless communications pairing system comprising:

• a receiver;
• a first transmitter coupled to the receiver, the first transmitter comprising:
• a processor configured to process data and execute a pairing process;
• and
• a memory coupled to the processor and configured to save data;
• and
• a second transmitter coupled to the first transmitter and configured to pair with the receiver;
• wherein after a first link between the first transmitter and the second transmitter is established, the processor of the first transmitter transmits pairing information to the second transmitter through the first link, a second link between the second transmitter and the receiver is established according to the pairing information after the second transmitter receives the pairing information, an image signal is transmitted from an image signal source coupled to the second transmitter to the second transmitter after the second transmitter is triggered, the second transmitter transmits extended display identification data (EDID) to a data processing device of the image signal source when the second transmitter is coupled to the image signal source, and the image signal source identifies the second transmitter as a virtual display device according to the EDID after the data processing device receives the EDID, the second transmitter processes the image signal for transmitting the image signal from the second transmitter to the receiver, and the receiver controls a display device for displaying an image according to the image signal.
