Major Progress

ABSTRACTThe first major progress towards complex LCD's has been made using arrays of thin film transistors (TFT's) fabricated using amorphous silicon (a - Si) technology. However, apart from other two and three terminal devices, there are also two new LCD technologies which directly improve the performance of the LCD without the need for extra switching elements. These are the supertwist (or STN) LCD and displays based on ferroelectric liquid crystals (FELC). These two alternative technologies are described and teir performance compared with that of displays fabricated using α - Si TFT's.

Important Significance

For the cholesteric liquid crystal (hereinafter short for Ch-LC) possesses special optical properties, it has specific applications in the area of liquid crystal displays and optoelectronic devices. Specimens of Ch-LCs in planar and focal conic texture stably are prepared. The photographs of textures are shot by polarizing microscope and transmittance spectrums of different textures are measured by spectrophotometer. It is found that the specimen in focal conic texture with large crystal domains has the well transmission property. The experiment has an important significance for applications of liquid crystals.
