A gate driving circuit includes a shift register circuit and an auxiliary circuit which are disposed at different sides of a pixel array. The shift register circuit includes an (N&#x2212;1)th shift register stage for generating an (N&#x2212;1)th gate signal according to a first clock, an Nth shift register stage for generating an Nth gate signal according to a second clock, and an (N+1)th shift register stage for generating an (N+1)th gate signal according to a third clock. The auxiliary circuit includes a first transistor. The first transistor performs the signal voltage stabilization and level switching acceleration operations on the Nth gate signal according to the (N&#x2212;1)th gate signal and the second clock.

Gate driving circuit with an auxiliary circuit for stabilizing gate signals

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.
