Abstract:
A touch control device with enhanced ESD protection effect comprises a sensing circuit module; a plurality of signal lines electrically connected with the sensing circuit module; an ESD protection ring disposed on periphery of the sensing circuit module and the signal lines; and an ESD shield ring interposed between the signal lines and the ESD protection ring. A touch on the sensing circuit module induces a sensation signal. While the signal lines transmit the sensation signal, the electrostatic charges generated thereby is drained off by the ESD protection ring. The ESD shield ring can drain off the residual electrostatic charges that the ESD protection ring does not drain off. Therefore, the present invention can exempt the touch control device from ESD interference, guarantee the accuracy of signal transmission, and protect the electronic elements of the touch control device.
