The total power dissipation is the sum of the static DC and the dynamic dissipation:
The static DC power dissipation is approximately:
The dynamic dissipation is, in the worst case (1 pixel On/ 1 pixel Off pattern):
where f is the video frequency and K the ratio between the active line and the total horizontal line duration.
Example:
We have:
Therefore:
