Abstract:
A display device comprising:a display panel having a display cell with a plurality of signal electrodes arrayed in columns, a plasma cell with discharge channels arrayed in rows, and a dielectric sheet interposed between said display cell and said plasma cell;a plasma driving circuit for sequentially driving said discharge channels to address said display cell;a correcting circuit for processing pixel signals through a corrective arithmetic operation to generate adjusted pixel signals, said corrective arithmetic operation comprising separate individual adjustment of the signal for each pixel depending on signal values of signals for pixels adjacent thereto, said correcting circuit taking into account crosstalk originating in the dielectric sheet to minimize such crosstalk, said correcting circuit emphasizing differences between pixel signal values for adjacent pixels by expanding the differences in generating the adjusted pixel signals; anda display driving circuit for supplying the adjusted pixel signals, which have been processed by said correcting circuit to said signal electrodes.
