METHOD AND APPARATUS FOR ELIMINATING IMPERFECT IMAGE, AND DISPLAY DEVICE

摘要

A method and an apparatus for eliminating an imperfect image, and a display device. The apparatus for eliminating an imperfect image comprises a multi-level grid circuit (1) and a gate drive module (2). The multi-level grid circuit (1) is used to receive a non-modulated gate turn-on voltage and output a modulated gate turn-on voltage according to an enable signal; the gate drive module (2) receives the non-modulated gate turn-on voltage and the modulated gate turn-on voltage output by the multi-level grid circuit, and outputs one of the non-modulated gate turn-on voltage and the modulated gate turn-on voltage for grid lines of each layer in the grid lines of different layers. In the method, it is not required to change the process of the panel, the time spent in eliminating the imperfect image is short, and the effect of eliminating the imperfect image can be controlled, thereby achieving high flexibility.
