Mode of transmission in touch screen?

I think you cannot use touchscreen devices as example to half-duplex system since these devices don’t work that way. Since you are wondering what is a half-duplex and what is a full-duplex, a half-duplex or HDX system allows communication in both directions but is limited to one direction only at a time and not simultaneously.

A good example of a device that uses half-duplex is the walkie-talkie. When using this kind of device when talking to somebody, you need to say “over” to acknowledge the other person that you are finished talking so he or she can now begin talking.

Normally, when somebody starts receiving the signal, he must wait for the transmitter to end transmitting before replying so that he can also transmit and receive the signal. A full-duplex system or FDX allows communication also in both directions but this time simultaneously. We can now use touchscreen devices as example in this kind of system.

These devices allow both callers to speak simultaneously and still be heard at the same time.
