| 摘 要： | 通过对TFT-LCD去隔行扫描输入信号易产生线残像的问题进行分析,考察线残像产生的原因与驱动信号之间的关联。结果表明,通过改变驱动信号的极性反转方式可以改善线残像,但改善线残像同时却带来了闪烁问题。经过进一步研究分析,通过增加预充电信号以及控制TFT特性的开关比可以有效解决改善输入信号后带来的闪烁问题,并给出了相应的原理解释。为线残像的分析和改善提供了解决方法和理论依据。

| Abstract: | The de-interlaced scan input signal is easy to produce line image sticking in TFT-LCD.This paper researched the relationship between line image sticking with the drive signal.The result shows that line image sticking can be reduced by changing the polarity inversion mode of drive signal.At the same time by adding the pre-charge and controlling the TFT current ratio of Ion/Ioff,the flash problem brought by changing drive signal could be resolved.The research established the solution and theoretical basis for line image sticking. |
