LG update on Cinema 3D firmware

by stevenparker76 / August 22, 2011 2:55 PM PDT

There's been a buzz here about active 3D TV vs. passive 3D
TV. I know there are people who prefer active 3D TVs because of the higher
image quality. Some, including myself, prefer passive 3D TVs because they are more
comfortable (flicker free and crosstalk free). Although some say that active 3D
TVs have superior 3D image quality over passive 3D TVs but I personally don't
think the difference is that noticeable. I mean, image quality on passive 3D TV
is perfectly good. But for those who are still concerned about the picture
quality on passive 3D TVs, LG recently updated its firmware on its Cinema 3D
series. According to flat panel review of LG's LW6500, its 3D system and
software were updated to improve 3D picture quality. I didn't know this but LG
Cinema 3D was awarded a full HD 3D certified by a German institute. I think
that says a lot about its picture quality. I wonder if I can get the update on
my TV (I already own a LW6500) or if the update is only on the new models.

Anyway, Long review short: LG's Cinema 3D used to show 2
frames in a time period of 1/200 seconds but now it shows 4 frames in the same
time period, showing 1080i for each eye. These combine to create a 1080p picture.

cinema 3D TV

Thanks for this post! I've seen seeing a lot of posts from people battling out active vs. passive. But you and I are on the same page. I prefer Cinema 3D since it's comfortable and I love the 3D glasses. Flicker free and crosstalk free means a lot since it means no headaches and a great viewing.
Also, I liked that you clarified that Cinema 3D *does* have full HD quality since some people seem to doubt it.
I think you made a mistake in the last part, though. It shows 540p for each and this combines to create a 1080p picture, right?
no worries, great post, anyway!

How can this work?
by LJoe2000 / August 24, 2011 3:53 AM PDT

Interlacing works by showing the even lines and then showing the odd lines, but the lines are shown in their proper orientation (even lines and odd lines are "interlaced" not "overlapped"). The passive filter on the TV will always send the even lines to one eye and the odd lines to another eye, so I can't see how they can ever show the filtered lines. All they could do is display the even and odd lines for the same eye in the same physical line positions on the screen, and I can't imagine that looking very good.
