| Summary: | 碩士 === 國立交通大學 === 照明與能源光電研究所 === 101 === Image sticking is one of the important factors to influence the quality and reliability of liquid crystal displays (LCDs). The mechanism of producing image sticking is very complicate, and it is not easy to analyze and overcome. However, the image sticking of LCDs can be improved by adjusting the driving to reach a minimized flicker signal, which can reduce the ions accumulation on the surfaces.
The flicker measurement system adopted by current LCDs industry have limits for measuring the flicker signals of LCDs operated at the high and low gray levels. Therefore, the driving of LCDs cannot be optimized at the low gray levels, and it causes the ions accumulation on the surfaces.
In this work, a flicker measurement system suitable for all grey levels was proposed and developed. The performance of our developed system was compared to the commercial system. The results showed that our system had superior detection sensitivity of flicker for all grey levels. Finally, we compared the driving setting, determined by the minimization of flicker signal, and the corresponding imaging sticking.
