Abstract

The invention provides an electrostatic protection circuit, a circuit board assembly and a liquid crystal display device. The electrostatic protection circuit comprises a time delay circuit, one end of which is electrically connected with a power port and the other end of which is grounded, and which generates a first control signal and a second control signal; the first switching circuit comprises a first end, a second end and a first control end, the first end is electrically connected with the output port and electrically connected with the input port through a first resistor, the second end is grounded, and the first control end receives a first control signal and controls the first switching circuit to be switched on or switched off; the second switching circuit comprises a third end, a fourth end and a second control end, the third end is electrically connected with the input port, the fourth end is grounded, and the second control end receives a second control signal and controls the second switching circuit to be switched on or switched off; when the first switching circuit is switched off and the second switching circuit is switched on, the input port is grounded through the second switching circuit. The electrostatic protection circuit has a good electrostatic protection function.

Description

technical field [0001] The present application relates to the field of display panels, in particular to an electrostatic protection circuit, a circuit board assembly and a liquid crystal display device. Background technique [0002] With the advancement of technology, electronic equipment with liquid crystal display devices has become a daily commodity in people's lives.
