Not long ago in the Forum there was a discussion about using different glasses in order for one of the viewers to see 3D and the other to see just 2D content. And although this is still not possible, it seems that Sony might be on the right track in providing such capabilities in near future, or at least the latest patents that the company has filed regarding the use of a single display with multiple shutter glasses and different image for the viewers can be used to help add such functionality. The two patents filed by Sony are for the principle of the new shutter glasses that will be able to share different images, and also the audio between two or more viewers on the same TV and for the methodology being used to utilize the sharing with these new shutter glasses.
The basic idea that Sony has is to use the even frames to display one type of image with 50/60Hz and the odd frames to display another type of image again with 50/60Hz and thus providing two different viewers two different pictures on a single TV (not two different 3D views, but two different 2D ones). And with the increase of response rate and the shutter speed of shutter glasses this can be further expanded to support a third viewer watching a completely different thing than the other two and probably this might be possible with even more than three. But don’t think that this is so easy to make and implement, while the viewers get a completely problem free and bright and contrasting image, there are a lot of possible issues, some of which are present in the current generation of hardware using shutter glasses. Still the possibility to play a game while somebody is watching a movie on the same TV sounds quite nice and usable, what do you think about the concept of TV sharing?
