WebTwisted nematic liquid crystal (TN LC) configurations [] are still the most widely used form of liquid crystal display mode.The LC director distribution and electro-optical characteristics of the TN cell are generally determined by the following three features: elastic forces in the LC which are described by Oseen-Frank free-energy density [], an electric field generated … WebTo determine number of discrete positions required (N), first determine the smallest incremental of measurement (I) required within 360 degree rotation: N = 360 / I. For example, if you require measuring down to 0.01 degrees, the resulting calculation would be N = 360 / (0.03) = 12,000 discrete positions. Next, convert the number of discrete ...
