Supertwisted nematic displays

As described above, the slope of TN displays, described by the ratio Vgo/ io for a NB mode operated cell, is in the range of 1.4-1.6, which is only sufficient for displays with a maximum number of multiplexed rows A = 16-32. For higher information content displays an increase of the slope is necessary to achieve a reasonable contrast ratio. In this subsection the influence of a twist angle 90° and other cell and material parameters on the midlayer tilt angle as a function of the reduced voltage, the so-called electrodistortional curve, is considered. [Pg.208]

The desire to improve sharjDness and viewing angle range led to the development of supertwisted nematic displays name suggests, STN displays have higher twist angles than the TN display, typically 220-270°. They are widely us laptop computers. [Pg.2563]

This supertwisted nematic display utilizes a twist of the Hquid crystal director of 270° within the ceU rather than 90° (45). The basic operation of the ceU is unchanged ia that the effect of the analyzer on light which has been rotated by 270° is the same as for 90° rotation. [Pg.203]

It can be safely predicted that applications of liquid crystals will expand in the future to more and more sophisticated areas of electronics. Potential applications of ferroelectric liquid crystals (e.g. fast shutters, complex multiplexed displays) are particularly exciting. The only LC that can show ferroelectric property is the chiral smectic C. Viable ferroelectric displays have however not yet materialized. Antifer-roelectric phases may also have good potential in display applications. Supertwisted nematic displays of twist artgles of around 240° and materials with low viscosity which respond relatively fast, have found considerable application. Another development is the polymer dispersed liquid crystal display in which small nematic droplets ( 2 gm in diameter) are formed in a polymer matrix. Liquid crystalline elastomers with novel physical properties would have many applications. [Pg.465]
