Temperature Compensation
For most applications, VDISP (pin 19) can be connected
directly to DGND (pin 36). 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. Figure 7 shows two circuits that can be
adjusted to give temperature compensation of about 10
mV/
°C between V+ (pin 24) and VDISP. The diode between
DGND and VDISP should have a low turn-ON voltage be-
cause VDISP cannot exceed 0.3V below DGND.
