Abstract:
A drive apparatus for driving a display panel having a plurality of row electrodes and a plurality of column electrodes intersecting with said row electrodes to form capacitive light-emitting elements, by applying pixel data to said column electrodes while successively applying scan pulses to said row electrodes said pixel pulses each representing a pixel data based on an input video signal, which comprises:a voltage source circuit for generating a resonance pulse source potential having a resonance amplitude variable to have a maximum potential level at a first predetermined potential and supplying the generated resonance pulse source potential to a voltage source line; and a picture element data pulse generating circuit for generating said pixel data on by connecting said voltage source line with either ones of said column electrodes in accordance with said picture element data so as to cause said picture data pulse to appear on said either one of the column electrodes, said voltage source circuit causing said resonance amplitude to decrease while keeping said maximum potential at said first predetermined potential when at least two of said pixel data neighboring each other in the column direction have the same logical value.
