Electrostatic protection circuit, electrostatic protection system and display device

The invention discloses an electrostatic protection circuit, an electrostatic protection system and a display device. The electrostatic protection circuit comprises a resistor branch circuit and a switch branch circuit, wherein one end of the resistor branch circuit is used for being connected with the signal input end of a power receiving module, the other end of the resistor branch circuit is used for being connected with the signal output end of a power supply module, one end of the switch branch circuit is used for being connected with the signal output end of the power receiving module, and the other end of the switch branch circuit is grounded; when voltage output by the signal output end of the power supply module is higher than preset voltage, the switch branch circuit is switched on. Thus, when static electricity is generated in the process that the power supply module provides voltage for the power receiving module, the electrostatic protection circuit enables instant high voltage generated by the static electricity to be grounded through the switch branch circuit, so that damage of the high voltage generated by the static electricity to the power receiving module is avoided.
