Abstract
A gate driver () and a display device, which relate to the technical field of display, and are applicable to the design and manufacture of display devices. The gate driver () comprises: a power-off voltage detection circuit () and a power-off de-ghosting function circuit () connected to the power-off voltage detection circuit (), wherein the power-off voltage detection circuit () is used for detecting a current voltage state, and outputting a control signal to the power-off de-ghosting function circuit () according to the voltage state, so that the power-off de-ghosting function circuit () outputs a signal to eliminate power-off ghosting according to the control signal. The gate driver () integrates the power-off voltage detection circuit () and the power-off de-ghosting function circuit (); the integration level is high, and the display device can eliminate the power-off ghosting without the need to match the selected type of the gate driver () and a printed circuit board.
