Abstract

This invention disclosed the sudden surge voltage protecting device of a passive array LCD. This invention mainly comprises plural voltage-inhibiting units relative to the electrodes of a passive array LCD. Each voltage-inhibiting unit is composed of at least two reversely connected voltage-inhibiting devices and one ground connection. Each voltage-inhibiting device can maintain at a fixed voltage value when inversed voltage is inputted and causes breakdown. When sudden positive or negative surge voltage is inputted to the electrode, one of the voltage-inhibiting devices will break down and the voltage level will be fixed at a specific value. Another voltage-inhibiting device that is not broken down is forward connected to output the sudden surge voltage via the ground connection such that the sudden surge voltage is not transmitted through the electrode into the LCD.
