Electro-static discharge protection circuit and liquid crystal display
An electro-static discharge protection circuit for a liquid crystal display is disclosed. In response to positive electro-static charges being generated on the signal line, a thin film transistor with a gate electrode connected to the high level signal line is switched on, and the positive electro-static charges are discharged through the switched on thin film transistor. In addition, in response to negative electro-static charges being generated on the signal line, a thin film transistor with a gate electrode connected to the low level signal line is switched on, and the negative electro-static charges are discharged through the switched on thin film transistor.
