Liquid crystal display nematic

In addition to the TN and IPS modes in nematic displays, himdreds of other displays methods were invented and tested over the last 30 years. Out of them the bistable nematic development based on surface flexoelectric interactions, the bistable cholesterics displays based on switching between planar and focal conic textures and the polymer dispersed liquid crystal displays found some applications. None of them, however, offer better than a few milliseconds switching time. [Pg.271]

Sub-milliseconds (and even sub-microseconds ) switching times so far are offered only by ferroelectric and antiferioelectric liquid crystals. Without aiming to review the majority of the possible display modes in ferroelectric smectic materials, i we just show the most known modes tested in SmC materials. [Pg.271]

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]

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]
