A data processing apparatus of an alternating current type plasma display panel system is disclosed. A plasma panel is divided into four subpanels by dividing vertically and horizontally, and 4 data interfacing sections take charge of driving the 4 subpanels, respectively. Numbers of upper and lower address electrodes are P. Each of the four data interfacing sections repeatedly receives N bits red-green-blue (RGB) data S times from a frame memory and, after storing a horizontal line RGB data, transfers D bits RGB data a time into 4 driving IC sections for driving address electrodes in a suitable order for data processing. Each of two driving IC sections for upper right and lower right subpanels takes charge of driving R address electrodes, and each of two driving IC sections for upper left and lower left subpanels takes charge of driving P-R address electrodes, where the number R can be decided by an equation, R=Nx[floor(P/N)]/2 and the operator floor(x) means a maximum integer which is not larger than the parameter x. Each of two data interfacing sections for upper right and lower right subpanels repeatedly receives the N bits RGB data floor{[floor(P/2)]/2} times from the frame memory, and each of two data interfacing sections for the upper left and lower left subpanels repeatedly receives the N bits RGB data S-floor{[floor(P/2)]/2} times from the frame memory. Accordingly, data interfacing chips for right subpanels and left subpanels can have an identical logic.
