The supply source comprises lamp drivers () and data processing means (). Each pair of different pairs of electrodes is coupled to a corresponding lamp driver. Each lamp driver is suitable to supply a high frequency supply voltage to the pair of electrodes to which the lamp driver is coupled. The data processing means is suitable to process input display data (D) and to control the lamp drivers such that their supplied supply voltages are dependent on the input display data.
