LG Display declares Active Shutter 3D TVs a health hazard, begins massive Passive 3D offensive

"LG found itself at the centre of a 3D storm at this week's CES, with its Display division warning of dire health consequences for users of Active Shutter 3D eyewear. 'It is not safe to place batteries and electronics so close to the brain,' proclaimed a spokesperson unambiguously, before tub-thumping the benefits of Passive Polarisation 3D TVs."

Then we will all die because of our cellphones and bluetooth headsets devices ...

Unless very serious studies backup this statement, I think that this is a very desperate way of selling their products ...

And if it's true then I am f"/$%%

I`ve purchase anodized aluminum screen. I managed to find one with smooth surface without any straps, scratches - just clear with ideally smooth structure. Like this other anodized piece this one is completely non reflective which work the best with strong light from projector. Finally i can keep flat screen and get properly set 3D effect (now it is very easy to put each picture in the same place). Effect is amazing. (...) Picture looks just perfect. Whole view is equally bright - without dark sides (like it use to be). Sharpness is even better than on white wall.
Sheet is very tough. Surface is very hard to damaged and it is stain resist. Sheet size 2500x1250 (1.5 mm thick) cost me: 88 £ / 105 Euro / 138 $.

I tested anodized aluminium sheet sample... as in description, it is also "non reflective", "ideally smooth structure" – ok for 2D, but doesn't work for 3D – it doesn't preserve enough polarisation. I guess, not all anodized aluminium sheets can be used as 3D screens. It would be very useful, if you could write in your first post ...manufacturer or shop, where you bought your anodized aluminium screen-sheet.

I`ve tested lots of different types of metal sheets and prblem was always the same - reflective light from projector. Anodized surface on aluminium prevent from it. I never noticed any difference betweene boards of metal in case of Stereo3D (depth, other quality).
Only problem i had was with Circular Polarization. LCD screens from my projectors been mixing colors through those filters and i had purple color in some areas.
Please check on the other metal to be sure that you got 3D at all. Play with filters, turn them each way. Maybe you did that - so i`m just guessing.
