Ultimate limits for matrix addressing of RMS-responding liquid-crystal displays

Abstract

A new general analysis of the addressing of an rms-responding matrix for uniform display of unrestricted patterns reveals the ultimate performance limit for any conceivable driving waveforms. The Alt and Pleshko limit for multiplexing can be exceeded whenever the number of matrix rows is not the square of an integer by appropriate choice of more general waveforms. A practical scheme for a two-line matrix yields a 24-percent improvement in voltage selection ratio over multiplexed addressing.
