Study Finds Little Difference Between Active, Passive 3DTV Glasses
A new study by TCO Development found little difference between 3DTVs that use active shutter or passive glasses, at least when it comes to the visual experience. "As a certification body with a long history in the field of visual ergonomics for displays, it is important for TCO Development to evaluate the visual ergonomics of these new technologies and to assess any possible impacts on the user experience. TCO Development will further investigate the need of a TCO Certification for 3D," said Niclas Rydell, product and certification director at TCO Development. Cross-talk, or ghosting, was low for both types of glasses, though proper height and distance placement was more important for a set using passive glasses. White luminance was three times lower for active shutter glass sets compared with passive sets. And the lower resolution available for a passive 3DTV (1920-by-540 vs. 1920-by-1080 for active shutter) is noticeable, but not too much of a drawback, the study concluded.
