Abstract
In this thesis, we studied the electro-optical properties of a liquid crystal cell applied nanoparticles as an alignment material. It was decomposed on the substrate by spin coating the mixture, POSS and Butanol. Based on Fowkes’ theory, we indicated that the nanoparticle POSS can induce vertical alignment. According to the experimental results, theoretical prediction, and simulation, we found that the anchoring energy was about 4.55×10-5 Jm-2. It was lower than the traditional PI vertical alignment layer. Meanwhile, the process temperature is about 80°C, which is suitable to fabricate flexible LC displays. Otherwise, the cell gap of flexible LC display was difficult to maintain under bending condition. So, we developed a reliable and rapid electro-optical measurement system for large area flexible liquid crystal displays. A 64-element photodiode array combined with simple bending mechanism was employed for 1D signal sampling. The system was also compared to another calibrated commercial system (Otuska5100). Both TV-curves and response time almost coincided with each other. The stability of the system was about 2.7 % and the time resolution was 1 msec.
