9 POWER DISSIPATION
The total power dissipation is the sum of the static
DC and the dynamic dissipation:
P
The static DC power dissipation is approximately:
P
The dynamic dissipation is, in the worst case (1
pixel On/ 1 pixel Off pattern):
P
where f is the video frequency and K the ratio be-
tween the active line and the total horizontal line
duration.

This worst thermal case must only be
considered for TJmax calculation.
Nevertheless, during the average life of the
circuit, the conditions are closer to the white
