Contrast Adjuster
Software can adjust 64-step contrast for an LCD by varying the liquid-crystal drive voltage (potential
difference between V
LCD
and V1) through the CT bits of the contrast adjustment register (electron volume
function). The value of a variable resistor between V
LCD
and V1 (VR) can be precisely adjusted in a 0.05 x
R unit within a range from 0.05 x R through 3.20 x R, where R is a reference resistance obtained by dividing
the total resistance.
The HD66750/1 incorporates a voltage-follower operational amplifier for each of V1 to V5 to reduce
current flowing through the internal bleeder resistors, which generate different liquid-crystal drive voltages.
Thus, CT5-0 bits must be adjusted so that potential difference between V
LCD
and V1 is 0.1 V or higher and
that between V4 and GND is 1.4 V or higher when liquid-crystal drives, particularly when the VR is small.
