4: FUNCTION DESCRIPTION

The S1D13700 provides a means of increasing the ability of expression on a monochrome liquid crystal
display. More specifically, it uses the OVLAY and DISP ON/OFF commands to display characters in inverse
video, produce halftone menu pads, and flash a given screen area for various highlighting effects as shown
below.
Use of the S1D13700’s layered function will efficiently accomplish the highlighting effects above. The
following describes a few examples of using this function to realize highlighting effects. Not all such effects
can be used within the same screen block, however.

Write turn-on data “1” to the entire graphic area where characters are
to be displayed in inverse video.
Specify an overlay method using the OVALY command so that the first
and second layers will be exclusive OR’d.
