Abstract

Official abstract text for this publication.

A gate driver ( 103 ) 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 ( 103 ) comprises: a power-off voltage detection circuit ( 101 ) and a power-off de-ghosting function circuit ( 204 ) connected to the power-off voltage detection circuit ( 101 ), wherein the power-off voltage detection circuit ( 101 ) is used for detecting a current voltage state, and outputting a control signal to the power-off de-ghosting function circuit ( 204 ) according to the voltage state, so that the power-off de-ghosting function circuit ( 204 ) outputs a signal to eliminate power-off ghosting according to the control signal. The gate driver ( 103 ) integrates the power-off voltage detection circuit ( 101 ) and the power-off de-ghosting function circuit ( 204 ); 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 ( 103 ) and a printed circuit board.

First claim

Opening claim text (preview).

What is claimed is: 1. A gate driver, comprising: a shift register, a level converter, a shutdown voltage detection circuit and a shutdown residual elimination functional circuit connected to the shutdown voltage detection circuit, wherein the shutdown voltage detection circuit is used for detecting a voltage state at present and outputting a control signal to the shutdown residual elimination functional circuit based on the voltage state, and the shutdown residual elimination f…
