Electro-optical Performance of STN-LCDs

This general description is typical for STN-LCDs with a twist angle 240° O 270°, pretilt angle 5° 0 10° and a cell gap, d 5 pm. The steepness of the electro-optical curve, y, should be as low as possible in order to optimise the number of lines to be addressed  

A large k z/ki 1 ratio also permits a greater tolerance of pitch variations for a given cell gap.
