13.11 Temperature control
Due to the temperature dependency of the liquid crystals
viscosity the LCD controlling voltage V
LCD
might have to
be increased at lower temperature to maintain optimum
contrast.
The V
LCD
at a specific temperature is calculated as follows
for both command sets. V
LCD
(at T = T
CUT
) is given by
equations(4) or (5),dependingonthecommandsetwhich
is used.

In the extended command set and basic command set
8 different temperature coefficients are available (see
Fig.34). The typical values of the different temperature
coefficients are given in Chapter 16. The coefficients are
proportional to the programmed V
LCD
.
Thebasicandextendedcommandsetdifferinthewaythat
the temperature coefficients can be accessed. In the basic
command set only one temperature coefficient is
available. However, the possibility exists to program the
default temperature coefficient by means of OTP
programming; see Chapter 22. In the extended command
set the different temperature coefficients are selected by
the interface with three bits TC[2:0].
