A gate driver including a shift register, a level shifter, an output buffer, and a processing unit. The shift register generates a shifted signal. The level shifter generates a level signal according to a first operation voltage, a second operation voltage and the shifted signal. The output buffer provides a scan signal according to the level signal. The processing unit controls the level signal to follow the second operation voltage when the first operation voltage equals to a first preset value and the second operation voltage is higher than a second preset value less than the first preset value. |
