The first application described was as temperature sensors by using a chiral nematic liquid crystal, which displays different colors at different temperatures. It is also worth noting that many common fluids are in fact liquid crystals. Soap, for instance, is a liquid crystal, and forms a variety of liquid crystal phases depending on its concentration in water. [Pg.407]

The twisted nematic liquid crystal display (TN-LCD) was reported by Schadt and Helfrich of F. Hoffman-La Roche in Basle, Switzerland in 1970. This was part of a tripartite collaboration between F. Hoffman-La Roche in Basle, Brown Boveri of Baden and Ebauche in Neuchatel, all in Switzerland. The intention was to design and develop flat panel displays, e.g. for digital watches. The first LCD factory was constructed in Lenzburg, Switzerland in the mid-1970s by Videlec, a subsidiary of Brown Boveri. Since then the TN-LCD has... [Pg.60]

Figure 9.13. A twisted-nematic liquid crystal display (LCD) equipped with a poly(ethylene)-silver nanocomposite that had been annealed at 180°C for 15 hr and subsequently drawn as described in the text. The drawing axis of the nanocomposite is oriented parallel to the polarizer in the left image and perpendicular in the right image.

The influence of the variation of several parameters on the maximum number of scanned lines of a reflective of transmissive twisted nematic liquid-crystal matrix display has been investigated by numerical calculation. [Pg.103]

Tilt angle has also an important influence on the performance of twisted nematic liquid crystal displays (TN-LCDs) because the electrooptical threshold and angular viewing uniformity decrease as the tilt angle is increased. >2 Thus it is important to be able to measure tilt accurately. Low initial tilt angles (<10 ) are of particular interest for multiplexed TN-LCDs. [Pg.115]
