Abstract

An electoluminescent display 1 with a plurality of display elements arranged in rows X and columns Y to form a matrix. Each element is connected to a row­conductor associated with its respective row and to a column-conductor associated with its respective column such that the element may be illuminated by applying a voltage across the conductors. The display further comprises a driver comprising a half H-bridges H1 etc. which are controlled by controller (3) so as sequentially to supply drive voltages from rail (7) Full drive voltage is supplied to a row-conductor of a row that is to be driven and one third drive voltage is supplied to the remaining row-conductors. The column-conductor(s) associated with the elements to be illuminated are grounded. Two thirds voltage is applied to the conductors associated with the remainder of the columns.
