Active is another name for alternate-eye, also referred to as shutter glasses and frame-sequential. The display alternates (very quickly) between showing an image to be seen by the right eye and a corresponding image for the left eye. The viewer wears glasses with liquid-crystal shutters synchronized so that each eyepiece becomes transparent at the appropriate times. There are flicker issues but there is less ghosting (a.k.a. crosstalk), and the screen is white, so colors are better. Passive is also called polarized; there are two images displayed at the same time, but the light creating each of them has been polarized (usually by filters on the projectors). The user wears polarized glasses, each eyepiece of which filters out the image intended for the other eye. There is no flicker but there are ghosting problems and a special silver screen is required, which causes color problems and has poor performance when viewed off-center. Roughly 25% of people think passive is best; 25% think active is best; 25% think they the same; and, 25% say it depends. Translation: check them both and see which you like better. |
