(1) as 0<m<n, if the addressing power consumption value that addressing power consumption detection module exports is greater than max-thresholds, then sub-fields data clearing process rank jumps directly to and is up to n; If the addressing power consumption value that addressing power consumption detection module exports is less than desired value, power consumption level is m-1; If the addressing power consumption value that addressing power consumption detection module exports is between max-thresholds and desired value, then sub-fields data resets process rank is m+1.
(2) as m=0, namely previous field picture signal does not reset process through sub-fields data, if the addressing power consumption value that addressing power consumption detection module exports is greater than max-thresholds, then sub-fields data clearing process rank jumps directly to and is up to n; If the addressing power consumption value that addressing power consumption detection module exports is less than desired value, it is still m that sub-fields data resets process rank; If the addressing power consumption value that addressing power consumption detection module exports is between max-thresholds and desired value, then sub-fields data resets process rank is m+1.
(3) as m=n, namely previous field picture signal resets process through the sub-fields data of highest level, if the addressing power consumption value that addressing power consumption detection module exports is greater than desired value, then sub-fields data resets process rank is still m; If the addressing power consumption value that addressing power consumption detection module exports is less than desired value, it is m-1 that sub-fields data resets process rank.
