液晶材料显示技术及未来展望.doc

科学前沿讲座论文 2014年6月 具有极其广泛的应用价值。随着以液晶显示器件为主的各类液晶产品的出现和发展，液晶已经深入到各行各业以及社会生活的各个角落。人类开发了液晶，液晶改变着人类生活。ABSTRACT The survival of mankind cannot do without information, the visual information accounts for more than half of the amount of information obtained, and the eyes, the most accurate and reliable, the vision is far more important than the other. Therefore the information display technology will play a very important role. As the important member of the liquid crystal display, with a wide range of applications. Along with the liquid crystal display device mainly various kinds of LCD products appearance and the development, liquid crystal display technology has been deep into all walks of life and every corner of social life. It has the advantages of low pressure, low power consumption and so on, in the flat panel display has a very large market share in the industry, has played an irreplaceable role in the process of transferring information. We now know, the liquid crystal molecules are having a dielectric anisotropy, in under the action of the power plant, the arrangement of liquid crystal molecules will change, can control the state of polarization of polarized light through the liquid crystal system. The human development of liquid crystal, liquid crystal changing human life.
