ABSTRACT:
A method for addressing an electro-optical display device having a display comprising display elements which adjoin one another and are arranged in a row, each display element having two electrodes of two different types which are opposite one another and are separated from one another by a liquid crystal. The electrodes of the first type are connected to one another groupwise in an electrically conducting manner and the electrodes of the second types are connected to one another segment-wise in an electrically conducting manner. For pointer-type representation of data on a contrasting background, at least three rectangular signals which are of the same type but out of phase with one another are applied via an adressing circuit to the electrodes of the display elements in such a way that in-phase signals are applied to the group electrode and the segment electrode of at least one data-bearing element and signals which are out of phase with one another are applied to the group electrodes and segment electrodes of the elements forming the background, the signals being such that the voltage between the electrodes of each of the other elements is greater than the threshold voltage of the liquid crystal. Also disclosed are an addressing circuit and a display device for carrying out the abovementioned method.
