Abstract:
1. A plasma display apparatus comprising: a controller which receives and processes an image signal, the controller having m channels for outputting image data, where m is a natural number greater than one; a data transmitter to transmit the image data through the m channels; a data driver comprising a data arranger having n channels to output addressing data transformed from the image data received through the data transmitter and a drive integrated circuit (IC) to generate an addressing pulse depending on the addressing data and outputting the addressing pulse, where n is a natural number greater than one; and a plasma display panel comprising an electrode for receiving the addressing pulse, wherein the number n is greater than the number m, and wherein the controller is configured to transmit the image data to the data arranger in any one of a plurality of input periods of one frame period through the data transmitter, wherein said plurality of input periods includes one or more of a reset period, an address period, or a sustain period, wherein the data arranger receives the image data through the data transmitter and rearranges the image data according to each of a plurality of subfields and generates the addressing data for output through the n channels based on the rearranged image data, wherein the data arranger comprises a memory to store image data corresponding to one frame, and wherein the data arranger and the drive integrated circuit (IC) are on one driving board, the controller is provided independently from the data driver, and the data transmitter further comprises a dummy channel.
