Liquid crystal display devices (LCDs) are increasingly being used for displays in various portable instruments. Almost all LCDs presently used in them are twisted nematic type LCDs (TN-LCDs) among many suggested display modes. However, as application of TN-LCDs .expands, their narrow viewing angle gradually becomes a problem, and hence it becomes necessary to look over the other display modes again to use them properly, consdering their characteristics. Therefore, in this paper, the authors tried to systemize various liquid crystal display modes according to their molecular alignments and their optical eflects, and summarize their characteristics.
As a recent trend of LCDs, the time-sharing multiplex or matrix driving technique for many segments has been generally used according to complexity of display information. This paper also describes about the driving technique and discusses the propriety of various display modes of liquid crystal to the technique.
