No conventional LCD tubes consume + 260w for the same brightness (always for 117cm) or ~ 60% more ...
There is no flicker in LCD, just the afterglow which causes blurring during tracking shots and rapid movements, which is offset with 200hz scan and even a plasma 400hz Neo PDP ...
but this has nothing to do with the backlighting ...
The low voltage (less than 230v) causes a loss of energy because of the transformations ... the high voltage also obviously ...
