Abstract
A flat panel display comprises a plurality of display elements (C) arranged in a matrix of rows (R) and columns, and first and second electrodes (Sc, Su) which are aligned with respect to each other and extend in a row or a column direction. The first and second electrodes (Sc, Su) form pairs which are associated with same display elements (C). An amount of electro-magnetical interference caused by currents through the first and second electrodes (Sc, Su) is decreased by driving the first and second electrodes (Sc, Su) in at least two groups such that the pairs are divided in two groups, and such that currents in pairs belonging to different groups flow in opposite directions.
