Abstract:
A color image display system, comprising:a plasma display panel operable for displaying a color image of selectable brightness gradations and comprising:a first substrate having a first main surface,plural elongated barrier ribs disposed on the first main surface, extending in a first direction and spaced in a second, different direction, pairs of adjacent barrier ribs defining corresponding elongated cavities therebetween,plural address electrodes respectively disposed within the plural elongated cavities, each address electrode being positioned between the adjacent barrier ribs of a corresponding pair thereof and extending throughout a length of the respective cavity,plural sets of color phosphor strips, each set comprising a common number of plural phosphor strips of respective, different colors received in a respective set of a corresponding number of adjacent cavities, each color phosphorous strip extending substantially continuously throughout the length of the corresponding cavity,a second substrate disposed on the first substrate and having a second main surface spaced from the first main surface, andplural pairs of display electrodes disposed on the second main surface and extending in the second direction, each pair of display electrodes crossing the plural address electrodes and defining, in association with each phosphor strip and respective address electrode, a respective sub-pixel and, in association with each set of color phosphor strips and respective set of addresses electrodes, a set of sub-pixels comprising a pixel of the display panel; anda driving system producing a driving waveform for driving said plasma display panel in accordance with color image data defining successive color images to be displayed in respective, successive image frames, the color image data of each image frame defining, for the associated set of sub-pixels of each pixel, respective relative brightness gradation levels and the driving waveform for each image frame comprising plural, successive subframe driving waveforms producing selectable, respective brightness gradation level increments, the driving system, in individual succession for the plural subframes of each image frame and respectively in successive address and drive periods of each subframe, selectively addressing and thereby selecting individual sub-pixels to be driven and commonly driving the selected sub-pixels for producing, as respective outputs thereof, the common brightness gradation level increment of the corresponding subframe and such that the composite of the respective increment outputs of each sub-pixel, selectively produced for the plural subframes of each image frame, corresponds to the respective relative brightness gradation level thereof for the image frame, as defined by the color image data.
