ABSTRACT:
An apparatus and method for preventing lock-up of an LCD it is provided, in which a voltage on a pin of the LCD is monitored, it is determined whether an electrostatic discharge (ESD) has been applied to the LCD based on the monitored voltage, and the LCD is reset if an ESD has been applied to the LCD. In a preferred embodiment, the LCD pin whose voltage is monitored exhibits a voltage level change, in response to an ESD, that is greater than a voltage level change exhibited by all other individual pins of the LCD. Because the LCD is reset only when an ESD condition has been detected, periodic blinking of the LCD is prevented.
