LG 3D TVs to arrive in May

Two different images are broadcast - simultaneously, one for each eye. The image for each eye is broadcast with a certain polarisation - red and green. Then the 3D glasses depolarise the images based on the colour of the lens. This ensures that each eye is getting a different image. The brain puts together these 2 different images, which gives you the perception of depth. That's why the TV needs to have a refresh rate of at least 60hz. 30hz (about 30fps) for each eye. Regular TVs have a refresh rate closer to 30hz, and if you had to broadcast 2 different image streams for each eye, you would effectively be seeing the image at 15fps, which would be really sucky.

Or something to that effect. Check Wikipedia for the exact technical explanation.

That is the worst explanation I've ever read :D

It confuses a total of three different 3D systems... And even gets their info wrong..

Google REALD for a proper explanation of 3D LCD TVs.
 
So its going to use red/green glasses not the linear polarisation system used at cinemas currently? That's sucky, no thanks. Regardless, you'll need quite a big TV for this to be anywhere near effective.

LOL.. I was afraid of that... But it somehow makes sense in my head...

/me heads to Wikipedia to learn
 
They use clear lenses which are polarised in a clockwise and counter clockwise direction, if I'm not mistaken, to match one of the lenses of the glasses.

no, google "3D LCD TV" rather - RealD is more of a movie theatre thing, which requires a specialized sony projector

afaik dolby3D can be achieved without the need for expensive TV sets or projectors

Linear Polarization - ok, I know what that is.
Circular Polarization - alright, instead of straight lines it's in circles.
Circular Polarization in a clockwise direction - WTF? A circle is a circle - how can you have a clockwise circle? The glasses don't spin, and I'm not doing cartwheels. How does that work?
 
I don't know guys

I thought the whole point of getting a 3D TV is that you don't need to use glasses

I saw a TV in the popular Mechanics the other month where the TV was designed in a special way that the 2 images are shown at different angles so on the screen so the screen has a corrugated iron effect.

So all they did was up the bandwidth of the HDMI port so it ver 1.4 now charged an arm and a leg for the screen and called it 3D what a waste of money

Do they supply only 1 pair of glasses with the TV what if your wife also wants to watch do they charge R1000 for additional glasses oh what if you have guests over they just will have to share

This is so stupid
 
Yep, once I can see 3D without glasses, I might think about taking 3D seriously. I am still of the opinion that 3D is a gimmick.

$200 - $300 more...that is R2000 - R3000. Not an arm and a leg.

Unfortunately $200-$300 overseas means after import duties, bribes to custom officials, bribes to local guavamunt parties to allow the product in, paying off the middle men, etc, it works out at R10000 - R20000 extra in stores in SA, which is an arm and a leg.
