Power
The supply voltage and power requirements are shown in the table below. The
power will vary greatly depending on the number of pixels lit and depending
on the chosen luminance level (see graph below.) Power levels will vary up to
+/-15 % from display to display due to brightness variation.

2) Abs Max power: 90% of pixels lit (yellow) per row, worst case display sample
2) Typical power: pattern with 10% of pixels lit per row, typical display
3) All power numbers are for LUMA open (no analog dimming)
