study on 3D systems for private use

AVTOP carried out a laboratory study on 3D systems for private use, with the aim of identifying potential sources of resolution losses.

The study describes factors than can cause a loss of resolution at various points of a 3D device chain. These include factors related to recording and transmission, factors related to reading and displaying the image, and factors related to 3D glasses and the way in which viewers perceive the picture.

To illustrate the potential pitfalls of combining qualitatively inferior devices within the chain, AVTOP’s study compared two 3D TVs: the Samsung UE46D7090, which uses active 3D technology, and the LG 47LW570S-ZD, which uses passive 3D technology.

As the diagram below shows, there were significant differences in the vertical resolution actually seen by the viewer. The active 3D system clearly outperformed the passive.

AVTOP’s concern is that if inferior 3D systems were combined with inferior 3D signals, the viewer could end up seeing less than 25% of Full HD resolution, despite manufacturers’ claims to offer Full HD in 3D.
