Check out the link above. It basically shows you how to make your own RF LF glasses.
How they work?
This technology is only available for passive sets at the moment. I'm not sure if Vizio, Panasonic, or Toshiba have it on their passive sets but I do know some of the LG 3D TVs have them. They work by showing one player the odd vertical pixels and the other player even vertical pixels. You will be able to see separate images taking up the whole screen.
I am planning to buy a LG55LM9600, how does its dual play work?
LM9600 has nice 3D effects but when you play in dual play mode, it's only in 2D mode.
When you invoke dual play in your game, let's say Call of Dutyl which requires more than two players. Then you go through the normal set up for split screen by using its magic motion remote. You may choose either vertical or horizontal mode which totally depends on you. and then put on its special glasses, there you go. Player 1 can only see his or her charactor in her own full screen while player 2 does the same.
It uses the passive 3D techonology that provides images to your left and right eyes seperately, so when the special glasses for each player only receive the same images constantly, players can only see their own screen.
This feature is really cool. I tried it when I attended an IT show a few weeks back. Actually, all the LG smart 3d tvs released this year will have this feature. But I heard that even last year models can enjoy this feature. I suppose you didn't choose LM9600 just because of it. I saw it and watched from it personally and image quality is really great.
That’s cool. I like the Dual play technology. But I thought it shows games in 3D mode. LG has done pretty good job. Beautiful design, zero level bezel, magic control, smart applications and this dual play mode make it different from other 3D TVs.
trepxe, you mean the horizontal pixels, right? Because that's how the passive sets work. And dual play does work in 3D, cutley7ad. The left and right eyes of a regular 3D set of glasses pick up odd and even horizontal pixels. So left picks up odd and right picks up even. But in dual play, the glasses are a bit different. One person would have glasses that only pick up odd pixels and the other would only pick up even pixels. So ultimately, two people would see two different images on one screen.
