Abstract
An improved matrix address system is disclosed wherein zero cross-talk and maximum contrast are obtained by utilizing a constant absolute magnitude data signal, and address and data signals in a voltage ratio equal to the square root of n, where n is the number of addressable columns and therefore the number of devices in a given row, so as to yield the maximum ratio, R, of the r.m.s. values of the 'on' voltage and the 'off' voltage applied to any given device, namely, R = 1 + 1/.sqroot.n.
