The control of a "Triplex" LCD module is described using the ?PD78P014.

There are a lot of applications existing, only a small display is necessary.

The connection of a "Static" display type is very easy, because there are only two voltage levels (VDD and VSS) to control as well on common as on segments lines. But for a multiplexed display type ("Duplex" or "Triplex") several intermediate voltage levels have to be controlled.
