The function 2D / 3D requires elaboration: 4 you are watching a 3D movie glasses with all the same (last) one wants to return to 2D (he only has to rotate the button to switch to 2D ) without disturbing others who are watching them in 3D to rest their eyes for example, since 3D TV sends signals.

Despite a weak packaging, Panasonic has made great efforts to improve the comfort of 3D.
Very satisfied, the price is high we get along well, however it starts to drop since 2012 with new TVs.
