1
The total power dissipated by the HVDD (or RGVDD) supply can be approximated using the equation
Total HVDD Power = [C
LOAD
× HVDD × Pixel Frequency] × HVDD
where C
LOAD
is the total capacitance seen by all H outputs.
Reducing the capacitive load and/or reducing the HVDD supply reduces the power dissipation.

LDO can be used to supply AVDD and DVDD only.
