An Explanation For The Drastic Reduction In Brightness In 3D

More questions / answers from the Panasonic Japan teams, with whom we have been having some excellent discussions. Why does brightness drop so much in 3D when things could be much closer to 2D levels with passive glasses?


Panasonic says that, yes, technically speaking the solution isn't difficult to put into place, but European energy standards pose a problem and stop them from putting into place the technology that would compensate for the respective falls in brightness and contrast of 40% and 70% commensurate with active glasses.

Increasing 3D brightness by 50% to compensate for the losses caused by alternating glasses would result in an increase in energy consumption of almost as much. This would mean TVs would no longer qualify for the same energy classifications and could even be barred from sale in Europe as a result!

Another argument in favour of passive technology...
