Operation of a plasma display panel device consists of a data loading time, an execution time for writing or erasing, and a normalization time following the write or erase during which the affected cells become stabilized. In practice, the times for these events are unequal since the serial data load to the matrix driver modules takes longer than the normalization time between write cycles. The serial organization results from the practical constraints of limited I/0 pins on integrated driver modules, limitations of the large-scale integrated circuitry in general. By way of example, 32 circuit driver modules may operate at a 3 MHz data rate, but the number of bits to be loaded in one scan line is sufficiently large that the loading time exceeds the normalization time.
