ABSTRACT:
A plasma display having a quartet type pixel structure provides a high grade and excellent picture quality picture and maintains good white balance and excellent intensity levels. The plasma display comprises a reference circuit .phi. for outputting a control signal based on the least significant bit of a digitized green video signal and a timing signal and an arithmetic circuit 8 for performing an arithmetic operation on the output of the reference circuit. As a result of this arrangement, the least significant bit information, that was lost by halving the green signal value to maintain the white balance is incorporated in the halved green signal based on a timing signal, thereby realizing 256 intensity levels without degrading the halftone in the video picture.
