Effect of Doped Insulating Nanoparticles on the Electro-Optical Characteristics of Nematic Liquid Crystals

Presenting information is essential in many aspects of our daily life. Among all display systems, liquid crystal display (LCD) occupies more than half of the display market as a whole on account of many advantages, including the flat panel, small weight, high definition, small driving voltages, and low power consumption. Currently, almost all LCDs are manufactured with nematic liquid crystal (LC) mixtures. And one of the most common modes for nematic LC displays is twisted nematic (TN) mode. Although the nematic LCs are the dominant materials in display market and for switchable optical devices, the degrading tendency of the performance is undoubtedly a significant barrier for practical applications. The performance of a LC device is mainly affected by the alignment layers and the LC mixtures used. One of the most crucial causes of performance degradation for nearly all the LCDs is the flowing ions within the LC devices. These ions may come from the LCs, the alignment layers, the surrounding glue, be generated by ultraviolet polymerization, or be produced during the filling
