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