摘要：

We investigated the relationship between line image sticking with different drive signal voltages and their inversion modes, because TFT-LCD easily produces line image sticking. The result shows that line image sticking and the coupling between common electrodes and data lines can be reduced by decreasing the drive signal voltage, or increasing the inverse-frequency of drive signal. When the gray level voltage is reduced from L255 to L46, the coupling voltage amplitude is reduced from 240 mV to 34.8 mV. When the driving signal changed from frame inversion to point inversion, the coupling voltage amplitude decreased from 112.6 mV to 63.1 mV. We also analyzed the mechanism of the inversion mode of drive signal on line image sticking by using Debye relaxation formula. The solution and theoretical basis were established for line image sticking by the research.
