: Since a characteristic of the STN LCD is that it has a longer response time (when switching dots On/Off) com-
pared to VFD display tubes (DM-D110 etc.), it becomes harder to display marquees that have a short interval for
text display (horizontal scrolling).
When displaying a marquee (horizontal scrolling), we recommend taking into account the display response time
for the LCD (250 to 350 msec), and set the text display interval to 600 msec or more.
