Abstract: An image data correction method and apparatus for a plasma display panel, and a plasma display panel device having the apparatus. The image data correction method calculates a load factor of video signals fed into a plasma display panel, and determines an automatic power control level corresponding to the calculated load factor. The method further involves generating sustain pulse information and the number of subfields and selecting a correction table corresponding to the number of subfields and the automatic power control level from the memory. Then, the image data is corrected with reference to the correction table. By this image data correction, white chromaticity can be maintained constantly while enhancing the color reproducibility of each subfield.

Abstract: An after-image prevention apparatus and method for a plasma display panel having a plurality of address electrodes and a plurality of scan and sustain electrodes arranged in pairs and in a zigzag pattern. An average signal level until the current frame from currently input picture data and an average signal level of each cell until the previous frame as stored in a memory section is calculated. The average signal level is compared with the picture data. An attenuation coefficient is generated corresponding to the difference between the average signal level and the picture data. The picture data is multiplied by the attenuation coefficient to output correction data, thereby preventing an after-image phenomenon on the plasma display panel.

Abstract: An apparatus for driving a plasma display panel and a method for processing pictures of a plasma display panel. An input video signal is converted into sub-field data. It is determined whether address consumption power of the sub-field data is high. When the address consumption power is high, interlaced scanning is carried out. It is determined whether lines having sub-field data items identical or similar in a row direction exist using the sub-field data. The lines are sequentially scanned. Accordingly, the number of times of switching address electrodes is reduced and thus the address consumption power is decreased.

Abstract: A gray scale expression method in a plasma display panel (PDP) and a driving apparatus for the PDP improves color coordinate adjustment. When the brightness coefficient of an input image signal is varied step by step in accordance with an external adjustment signal, a dithering algorithm is applied to the image signal to vary the gray scale of the image signal by 0.25 for every variation of the brightness coefficient. The dithering algorithm is applied to the pixels or frames of the input image signal such that the pixels or frames exhibit opposite characteristics in a time direction.
