发明名称 Wechselstromplasmaanzeigetafel und Steuerungsverfahren dafür
摘要 A method for driving an AC-driven PDP to produce gradation display by dividing a field into at least three sub-fields in time sequence, each of the sub-fields having a weighted luminance and being provided with an address period for selecting a cell to emit light for display and a sustain period for sustaining a light-emitting state. The method includes the steps of grouping the sub-fields into at least two sub-field groups, carrying out a charge forming operation, as preparation for addressing, directly before each of the sub-field groups so as to form wall charge necessary for sustaining the light-emitting state in all cells on an entire screen, and carrying out an erase addressing, in the address period of each of the sub-fields, for erasing the wall charge in a cell which need not emit light. <IMAGE>
