Problems solved by technology

This method can solve the afterimage problem caused by the charge stored in the capacitor that cannot be quickly released when the liquid crystal display displays the same picture for a long time and switches to the next picture without affecting the normal display effect.

Embodiment 1

[0028] Such as image 3 Shown, a kind of liquid crystal display shows the improvement method of afterimage, and this liquid crystal display comprises some source lines and some gate lines, and described source line and gate line are respectively driven by source and gate drive control, comprises the following steps:

[0029] S1: preset the number of frames at which the source driver and the gate driver respectively send charge elimination signals to the source line and the gate line;

[0030] The preset number of frames at which the charge elimination signal is sent is 1 to 3530 frames, preferably, the preset number of frames at which the charge elimination signal is sent is 1 frame.

[0031] S2: judging whether the number of frames of the source line and the gate line executing normal picture signals reaches a preset interval frame number: if so, the source driver and the gate driver send charge elimination signals to the source line and the gate line respectively; If not, t...

Embodiment 2

[0040] Such as image 3 Shown, a kind of liquid crystal display shows the improvement method of afterimage, and this liquid crystal display comprises some source lines and some gate lines, and described source line and gate line are respectively driven by source and gate drive control, comprises the following steps:

[0041] S1: preset the number of frames at which the source driver and the gate driver respectively send charge elimination signals to the source line and the gate line;

[0042] The preset number of frames at which the charge elimination signal is sent is 1 to 3530 frames, preferably, the preset number of frames at which the charge elimination signal is sent is 1 frame.

[0043] S2: judging whether the number of frames of the source line and the gate line executing normal picture signals reaches a preset interval frame number: if so, the source driver and the gate driver send charge elimination signals to the source line and the gate line respectively; If not, t...

Abstract

The present invention discloses a liquid crystal display ghost improvement method. The liquid crystal display comprises a plurality of source lines and a plurality of gate lines, the source lines and the gate lines are respectively controlled by the source driving and the gate driving, the source driving and the gate driving send charge elimination signals to the source lines and the gate lines at a certain frame number interval, and after the source lines and the gate lines executes the charge elimination signals, the next frame normal frame signals are executed once again. The liquid crystal display ghost improvement method can solve the problem of the generate ghost because the residual charges in a capacitor cannot be rapidly released when the liquid crystal display displays the same frame for a long time and converts the frame to the next frame in the condition that the normal display effect of the liquid crystal display is not influenced.

Description

technical field [0001] The invention relates to the field of liquid crystal displays, in particular to a method for improving residual images displayed on a liquid crystal display. Background technique [0002] In the current TFT-LCD, due to process problems, the VCOM compensation of the IC cannot achieve complete symmetry of the positive and negative source voltages. Usually, when the same picture is displayed for too long, the LCD will leave an afterimage of the previous picture in the next picture. This is because when the same picture is displayed for a long time, the charged ions in the liquid crystal are adsorbed on the upper and lower glass ends. , and form a built-in electric field, these ions are not released immediately after the screen is switched, so that the liquid crystal molecules do not immediately turn to the angle that should be turned. Contents of the invention [0003] In order to solve the above-mentioned shortcomings of the prior art, the present inv...
