Abstract
In an LCD source driver, to enhance the ESD performance thereof, there is provided a path in a device area penetrating thereacross such that an internal power wire or an internal ground wire to connect between an output pad and a power-rail ESD clamp circuit on two margins, respectively, of the LCD source driver could pass through the path to shorten the internal power wire or the internal ground wire and thereby to avoid chip area increase for the ESD mechanism.
