One technique for operating a plasma display in video mode is to write and then erase a line followed by a selective write operation in order to update the panel contents in video mode. For fast update time and/or large panel size, it is desirable to minimize the erase time. The inherent feature of the plasma panel provides persistence during the time pels (picture elements) in other parts of the plasma panel are being updated. If a block of lines is totally erased in one operation, it can be followed by selective write operations for each line, thereby allowing prorating of the erase time over the time for writing each line. Successive blocks of lines are operated on in this fashion until the entire frame is complete.
