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

LDO should be used to supply only AVDD and DVDD.
