Block Diagram
To drive a dot matrix display, both the columns and the rows need to be independently driven. Figure 1 shows how a
PLASMADOT
row that sinks that current to the return supply. When the display is scanned, only one row driver is on at a time but any number of
the column drivers can be on.
Display Intensity Control:
There are two methods of controlling the brightness of the display.
With either method of intensity control, it should be noted that the intensity of a DC plasma display is not linear with the pixels on
time. (i.e. The pixel is not half as bright when left on for half the time.)

To control the brightness of the entire display, vary the display on time with the DE signal.
Second method is by frame rate modulation, this method requires less hardware complexity but limits the number of intensity
levels that may be achieve.
