An Operating Circuits Design for preventing Electrostatic Discharge in Liquid Crystal Displays

An electrostatic discharge (ESD) or a noise supplied from the outside has an effect on communication between the timing controller (TCON) and the memory element (EEPROM) through the interface between the timing controller and the memory element in liquid crystal displays (LCD). Therefore, we must apply ESD protection methods to LCD operating circuits for a normal operation. Our ESD protection circuit is to prevent from bi-directional communication errors between TCON and EEPROM due to an electrostatic discharge (ESD).
