Abstract
In a fast-scan mode of addressing a matrix of m rows and n columns, in which the columns are scanned, contrast is optimized by maximizing the ratio of the rms voltage at a selected intersection to that at a nonselected one. A simple derivation shows that the address-pulse amplitude should be taken proportional to n1/2. We apply this result to the twisted nematic case.
