Question by PenguinFan20085: Are there any physical differences between a regular lcd/led TV and an lcd/led tv that is 3D capable?
I mean if I had two same brand 47″ LED TV’s, one badged as LED the other badged as LED and 3D capable, and I took a screwdriver and pry bar and tore it down to a component/board level, would I find anything in the 3D TV that wasn’t in the regular TV?

There is 2 current types of 3d tv, both having physical differences:
1) Active 3D: in this type of television the physical differences is an added module to communicate with the active shutter glasses to keep them in sync. This will enable the television to display the correct frame at the same time as the glasses.
2) Passive 3D: They add a polarized filter in front of the screen in a passive 3d tv. This enable the pixels to have a different polarized light, thus creating 2 images with different polarization at the same time.
So from a manufacturer stand point, they can relatively easy take any of their television and convert them to 3D (but in the active shutter case, the television need to have a high enough refresh rate to alternate between the two)
