If a CRT adapter drives a memory type of plasma panel, the vertical retrace can be used to erase all pels (picture elements) on a first scan line. This is followed by selective writing on the line and erase of the adjacent line. This process is repeated through the entire panel for a complete frame. The memory feature of the panel maintains the illumination of lit pels until the erase of the next frame, providing infinite persistence unless an update of data in a later frame leaves the pel erased at the selective write time. In order to provide high-speed operation, it is necessary to maintain fast update times of the individual pels. The erase and write cycles should be short and, if possible, combined with sustain.
