Abstract:
A method of driving an electric discharge display panel, which has a color pixel array of vertical stripes type, pluralities of parallel scan and sustained discharge electrodes provided alternately on the same insulating substrate as that with the color pixel array thereon and having a double side discharge electrode structure striding two adjacent pixel columns, and a plurality of column electrodes extending perpendicular to and insulated from the scan and sustained discharge electrodes, wherein:the scan and sustained discharge electrodes are grouped in two, namely, odd and even, electrode groups, one field being constituted by a plurality of sub-fields for gradation display, the sub-fields being grouped into those for odd pixel column display and those for even pixel column display;the odd pixel column display sub-fields are each arranged such that, in a write period, the same display data is simultaneously written through write discharge in two adjacent pixel columns on the opposite sides of each scan electrode and, in a sustained discharge period, sustained discharge of only the odd pixel column pixels is caused by applying a sustained discharge pulse alternately to the scan and sustained discharge electrodes of the odd pixel column pixels and applying the same waveform sustained discharge pulse to the scan and sustained discharge electrodes of the even pixel column pixels;the even pixel column display sub-fields are each arranged such that, in a write period, the same display data is simultaneously written through write discharge in two adjacent pixel columns on the opposite sides of each scan electrode and, in a sustained discharge period, sustained discharge of only the even pixel column pixels is caused by applying a sustained discharge pulses alternately to the scan electrodes and sustained discharge electrodes of the even pixel column pixels and applying the same waveform sustained discharge pulse to the scan and sustained discharge electrodes of the odd pixel column pixels; andthe odd and even pixel column display sub-fields are combined such as to cause independent display light emission of all the display face pixels.
