Abstract:
1. An apparatus for driving a plasma display panel, comprising: a signal processor for converting an external image signal into image data suitable for driving the plasma display panel; a data arranger for reconstructing the image data to a plurality of sub-fields in order to process the gray scale of the image data converted by the signal processor and serially transmitting control data corresponding to one or more scan lines; an X-electrode driver for receiving the control data corresponding to one or more scan lines from the data arranger and applying an address pulse corresponding to the control data to X electrodes; a Y-electrode driver for applying a scan pulse for addressing and a sustain pulse for maintaining a discharge to Y electrodes; a Z-electrode driver for applying the sustain pulse for maintaining a discharge to Z electrodes; a main controller for performing a control operation to sequentially read out the image data reconstructed by the data arranger according to the external image signal and to transmit the control data corresponding to one or more scan lines to the X-electrode driver; wherein the data arranger is coupled between the main controller and X-electrode driver and includes an integrated temporary storage for temporarily storing 6-bit control data corresponding to only one scan line at a time, wherein the integrated temporary storage has a 6-bit storage capacity for storing the 6-bit control data corresponding to only the one scan line, wherein the X-electrode driver includes a plurality of data integrated circuits for serially receiving the 6-bit control data corresponding to one scan line stored in the integrated temporary storage, wherein an output terminal assembly of the integrated temporary storage includes a first pin to output a select signal to select one of the plurality of data integrated circuits, and a second pin to serially transmit the image data stored in the integrated temporary storage, and wherein the first and second pins are directly connected to each of the data integrated circuits.
