ABSTRACT:
A method of driving a matrix display device in which each display element (e.g. a liquid crystal display element) is connected in series with a non-linear resistance element, utilizing row scanning signals which vary periodically between 4 different potentials, the potentials being selected such that an alternating bias potential is applied to each display element both in the non-activated and in the activated state thereof, and such that satisfactory operation can be attained using non-linear resistance elements having a threshold voltage which is considerably lower than has been practicable in the prior art, e.g. with the threshold voltage of a single PN junction being utilizable.
