The peak-to-peak LCD drive voltage is equal to (V DD –
V DISP ). In the 40-pin dual in-line package (DIP), V DISP
is internally connected to DGND, providing a typical
LCD drive voltage of 5V P-P .
For applications with a wide temperature range, some
LCDs require that the drive levels vary with temperature
to maintain good viewing angle and display contrast. In
this case, the TC820 44-pin package provides a pin
connection for V DISP . Figure 5-16 shows TC820 circuits

that can be adjusted to give a temperature compensa-
tion of about 10mV/°C between V DD and V DISP . The
diode between GND and V DISP should have a low turn
on voltage because V DISP cannot exceed 0.3V below
GND.
