Abstract
An electrostatic discharge protection circuit and a display apparatus are provided. The electrostatic discharge protection circuit adapted to the display apparatus having a display panel which has a signal line and a common voltage line. The electrostatic discharge protection circuit includes a first switching unit and a second switching unit. The first switching unit is electrically coupled to the signal line. The second switching unit is electronically coupled between the first switching unit and the common voltage line. When the display apparatus is shut down, the first switching unit and the second switching unit form a conductive path. When the display apparatus is turned on, the first switching unit receives a first control signal, and the second switching unit receives a second control signal, so that at least one of the first switching unit and the second switching unit is turned off at the same time.
