In the 1980s, the research and development of AM LCDs were very active, but it had not yet opened great application. On the other hand, STN-LCD (super twisted nematic LCDs) for PCs and Japanese word processors were realized in the 1980s [7], and also colored STN-LCDs for PCs were developed. The electro-optical response increased steeply with increasing applied voltage for those cells and enough contrast was provided even if the number of scanning lines increased, and... [Pg.56]

The wide view film (WV film) was developed by FUJlblLM Co., Ltd. (see Fig. 4.5) and released in December 1995. It is an optical compensation film for liquid crystal displays (LCDs). LC display modes are classified into several categories, but the most widely used mode for note PCs, monitors, and cell phones was the TN (twisted nematic) LCD because of its low power consumption. [Pg.95]

Table 4.1 summarizes which type of the LC film series is compatible for each LCD mode. Twisted oriented films can be used for color compensation of STN (super twisted nematic)-LCDs [36], in particular for color STN-LCDs in mobile devices. Because such color mobile STN-LCDs use only one polarizer, it is necessary that the combination of the compensation film and STN cell functions as a wideband A/4 plate. Multiple films are required in order to achieve this condition for usual, stretched films, but by using the twisted oriented film this can be realized by just one film [37-39]. [Pg.114]
