An AC color plasma display system comprises an AC plasma display panel having transversely oriented first and second insulated electrode arrays defining a matrix of display pixels. Linear ribs are in substantially parallel alignment with one of the linear electrode arrays to form gas channels, respectively, aligned electrodes in one of the arrays. A plurality of phosphor layers are on the ribs, and a UV rich gas discharge medium is sealed in the channels. An interface circuit for receiving video signals from one of a selected plurality of video sources produces, in digital form, pixel data, pixel clock, and horizontal and vertical synchronizing signals from a gray scale drive system is connected between said interface circuit and AC plasma display panel. The gray scale drive system includes blue, green and red color channels and pixel-by-pixel gray scale control of each color channel. The gray scale drive system includes circuits for supplying write, erase, and sustaining potentials to said electrode to arrays and perform the following operations: 1) supply said write potential to all said electrodes to cause all pixels to be in an "on" state, 2) supply said erase potential to selected ones of said electrodes to erase selected pixels and cause the selected pixels to be in an "off" state, and 3) supply a burst of sustaining potentials to the electrode arrays for predetermined number of cycles to cause the pixels in the "on" state to emit light for each sustainer cycle, and repeating operations 1, 2 and 3 a predetermined number of times.
