The invention relates to an arrangement for driving a display device with columns and rows in which different voltage values may be fed to columns of the display device in dependence upon the data to be displayed. The invention also relates to a display device with a driving arrangement. In order to provide an arrangement for driving a display device in which the energy consumption is reduced, an arrangement (1, 40) for driving a display device (2) with columns and rows is proposed in which voltages can be fed to the columns of the display device voltages in dependence on the data to be supplied, with two supply voltage lines carrying a maximum and a minimum column voltage (Vcolmax and Vcolmin), wherein at least one voltage divider unit (43) is arranged between the supply voltage lines for the generation of divided voltage values, and a supply of the divided voltage values to column output circuits (41N) is provided, with a column output circuit (41N) comprising at least one switching matrix (411) and/or amplifier unit (412), it being possible to disconnect the switching matrix and/or amplifier units from the supply voltage lines by means of switches (S1, S2) and to connect one of the supply voltages to a column output by means of switches (S3-S5).
