Display method for distinguishing multiple linking targets

A display method for distinguishing multiple linking targets to switch data transmission link between an input device and at least two information processing systems through a plurality of transmission channels in a wireless transmission fashion, the input device including a display module with a first display zone and a second display zone, the display method comprising the steps of:

• step 1:
• activating a detection mode for a linking target to detect the linkable information processing systems;
• step 2:
• getting a device identification code and a device authorization code of each information processing system, and setting a transmission channel selection code corresponding to the device identification code and the device authorization code for reading thereof;
• step 3:
• reading the corresponding device identification code and the device authorization code through the transmission channel selection code generated by selection of a user to establish a data transmission link between the corresponding transmission channel and the information processing system;
• and
• step 4:
• getting the generated transmission channel selection code and the corresponding device identification code through the display module, and displaying the transmission channel selection code through the first display zone and displaying the device identification code through the second display zone.
