For image data of each display cell, correction is performed with data from a correction memory (12) and stored in an image memory (14). A sequencer sends a signal regarding a display pulse within one frame to a sequence counter (22), which the sequence counter counts. A value corresponding to the count value is read out from a look up table (24), and a comparator compares the image data for one display cell from the image memory with a value (number of discharges or value corresponding to brightness) regarding the display pulse converted from the lookup table (24). When the value from the lookup table (24) reaches the value of the image data, the display data is changed so as to control the state of discharge (such as to stop the discharge). The number of discharges corresponding to the image data is controlled by the contents of the lookup table (24) so that the brightness can be controlled and correction is easily performed. <IMAGE> |
