ABSTRACT:
A plasma display apparatus is disclosed wherein a column electrode driver for a PDP has a simpler constitution to facilitate wirings between the column electrode driver and column electrodes in the PDP. A plasma display apparatus comprises a plasma display panel having a plurality of row electrodes, and a plurality of column electrodes extending perpendicularly to the plurality of row electrodes, wherein the plurality of column electrodes are divided into first, second, and third row electrode groups corresponding to discharge cells of red, green, and blue; a first unit for driving the plurality of column electrodes on the basis of digital video data for red, green, and blue; a second unit for driving the row electrodes, wherein the first unit for driving said plurality of column electrodes comprises a first shift register for receiving the digital video data for red, a second shift register for receiving the digital video data for green, a third shift register for receiving the digital video data for blue, and a latch circuit for latching outputs of the first, second, and third shift registers to position the latched outputs in the manner that the latched outputs are associated with the corresponding first, second, and third row electrode groups.
