Abstract

The invention provides for a method and display apparatus (10) having driving circuitry for driving a display panel (24) having a plurality of addressable discharge cells (26) driven by display pulses (DP), including the steps of applying data pulses (DAP) during the time interval between display pulses (DP) and characterized by the step of priming charges for each of the discharge cells (26) by means of the reset discharges so as to reduce the required data voltage, and in particular such a method wherein one TV-field period (TF) is divided into a plurality of sub-fields (SF) all of which are of substantially equal time durations.
