Single-cable bidirectional communication-based touch control display method and system

摘要

A single-cable bidirectional communication-based touch control display method and system for enabling communication and transmission between a portable electronic device having a first medium access address and a touch control display device having a second medium access address are provided. The method includes sending a video signal generated by the portable electronic device to the touch control display device via a single transmission cable to display the video signal on the touch control display device; touching, by a user, the touch control display device based on the video signal to generate a touch signal configured as a data packet according to an Internet Protocol frame; and sending the data packet back to the portable electronic device via the transmission cable, such that the portable electronic device retrieves the touch signal from the data packet to generate and feed another video signal back to the touch control display device.
