Generating a Temperature Compensated Display Drive Voltage
Temperature has an important effect in the variation of
threshold voltage in multiplexed LCD displays. As
temperature rises, the threshold voltage goes down. For
applications where the display temperature varies widely, a
temperature compensated display voltage, V
DISP
, can be
generated using the ICL7663S. This is shown in Figure 11
for the ICM7233 triplexed LCD display driver.
