Abstract
An electrode array for an electrooptical facsimile recorder and a method of controlling this electrode array are disclosed. A plurality of spot electrodes are inserted between two main electrodes deposited on a lead lanthanum zirconate titanate (PLZT) substrate. In this manner, three partial lines of electrically controllable light gates are formed which provide a line-at-a-time output of the information to be reproduced. The individual light gates are controlled by driver ICs with push-pull output stages. To control the individual partial lines, different voltages must be applied to the main and spot electrodes.
