ABSTRACT:
An electrostatic discharge (ESD) protection circuit and an ESD protection method applied in a liquid crystal display are provided. The ESD protection circuit comprises a first thin film transistor (TFT), a second TFT, a first diode and a second diode. The liquid crystal display has a signal line and a common electrode. The ESD protection method comprises the following steps. When a first electrostatic charge is generated on the signal line, the corresponding voltage of the first electrostatic charge enables the first diode to be conducted, so that the first electrostatic charge is discharged to the common electrode through the first TFT. When the second electrostatic charge is generate on common electrode, the corresponding voltage of the second electrostatic charge enables the second diode to be conducted, so that the second electrostatic charge is discharged to the signal line through the second TFT.
