ET MULTIPLICATION FACTOR
The Set multiplication factor (SETMUL) command sets the multiplication factor of voltage multiplier 1. A detailed
explanation of the LCD voltage supply architecture is given in Section 7.8.
The different multiplication factor settings for voltage multiplier 1 are given in Table 63.

TCVOP
SLOPES
A, B, C
AND
D
The Set TCVOP slopes A, B, C and D (TCVOPAB and TCVOPCD) command splits the temperature range into 4 parts
and can be programmed by using the following commands.
Due to the temperature dependency of the liquid crystals viscosity, the LCD controlling voltage V
LCD
might have to be
adjusted at different temperatures to maintain optimum contrast.
There are four equally spaced temperature regions. For each temperature region a different temperature coefficient can
be selected. Each coefficient can be selected from a choice of eight different slopes, or multiplication factors
(see Table 66) bysetting TCVOPAB and TCVOPCD. The controlled V
LCD
will not bechanged linearly, butin 40 mV steps
(parameter b in Table 47). Slopes SLA, SLB, SLC and SLD are overwritten by OTP values if these are set.
