Claim:
1. A touch control device with enhanced electrostatic discharge protection effect, comprising a sensing circuit module; a plurality of signal lines electrically connected with said sensing circuit module for transmitting signals; an ESD (Electrostatic Discharge) protection ring disposed on periphery of said sensing circuit module and said signal lines, wherein electrostatic charges generated at a time point that said signal lines transmit signals to said sensing circuit module are conducted to said ESD protection ring; and an ESD shield ring disposed on periphery of said sensing circuit module and said signal lines, interposed between said signal lines and said ESD protection ring, and draining off residual electrostatic charges that said ESD protection ring does not drain off; wherein a width of said ESD shield ring is smaller than a width of said ESD protection ring.
