2.2.2 External Divider Chain
The different display voltage levels are supplied by an external resistor chain as shown in fig. below.
Two different configurations with five or four display voltage levels can be chosen.
The resistors have to have a good matching within < 1% to avoid DC voltage levels on the liquid crystal
device.
DC levels trigger electrode reactions on the liquid crystal cell, deteriorating display quality rapidly.
