Temperature adjustment of the VLCD
Due to the temperature dependency of the liquid crystal viscosity, the LCD supply voltage
may have to be adjusted at different temperatures to maintain optimal contrast. The
temperature characteristics of the liquid is provided by the LCD manufacturer. The slope
has to be set to compensate for the liquid behavior. Internal temperature compensation
can be enabled via bit TCE (see Table 17 on page 15).
The ambient temperature range is split up to six programmable regions and to each a
different temperature coefficient can be applied (see Figure 23).
