Abstract

A capacitive touch control device includes a plurality of switching assemblies for being respectively connected to transmitting wires that connect a capacitive electrode layer. Each of the switching assemblies includes a switch, a touch drive circuit, and an antenna circuit, the latter two of which are installed to the switch. Each of the switches is provided for being connected to the corresponding transmitting wire, and is configured to be in a touch mode by electrically coupling to the touch drive circuit or in an antenna mode by electrically coupling to the antenna circuit. When the switches are in the touch mode, the switching assemblies enable the capacitive electrode layer to provide a capacitive touch function. When at least one of the switches is in the antenna mode, the corresponding switching assembly enables the capacitive electrode layer to provide an antenna function.
