Although Twisted Nematic LCDs may be driven in a time?

multiplexed fashion to increase the display information,?

they are restricted in terms of reduced contrast and limited?

viewing angle. To achieve more highly multiplexed displays,?

super twist technology is applied.

Super Twisted Nematic LCDs have a twist that is greater

than 90° but less than 360°. Currently most STN displays

?are made with a twist between 180° and 270°. The higher

?twist angles cause steeper threshold curves which put the?

on and off voltages closer together. The steeper thresholds?

allow multiplex rates greater than 32 to be achieved.
