3d glasses weird but good weird
Maybe somebody like roller11 with a background in electronics would care to comment on this.
I have had my system w/3d glasses since approx. mid Oct. 2010.

I noticed the first time using the samsung 3d glasses that whenever I turned on the glasses that the
on/off button on the answering machine of my vtech model# cs6229-3 portable dect6.0 phone would start
blinking on and off as well.
I always have the answering machine turned on, so the light is always on as well.
I only see the blinking when the glasses are turned on and while looking through the glasses.
When the glasses are turned off I just see a steady red light thru them.
This button is red in color. It has a frosty looking clear plastic cap over what i assume is a red
led light underneath.
This is actually a quite helpful unintended consequence, as I am able to verify that my glasses are
indeed on or off. It's much easier than taking the glasses off and fiddling with the little button
on top of the frames. The phone base is right there on my computer desk.

I'm not griping at all, just curious!
Has anybody else experienced this?
Could there be some kind of practical application for this phenomenon?

Quite simple.
LED on your answering machine is not 'on' constantly, but is blinking on/off all time, but with higher frequency, like 100Hz.
So, without glasses it seems just to be ON, while with glasses, it's different story :)

Haha, yes I took a call during a 3D gaming session and for a second thought my cell phone screen was toast. Flickering bigtime with the 3D glasses on! Never thought about the cell screen having a refresh rate...duh!

I see the same thing when I look at the LED read out on my A/V receiver

I can't read my cordless phone screen with my glasses on =P It just looks black lol, looks fine without them =D And if I look at my neighbours TV across the road I can see their screen flickering like a madman lol.

That's because the glasses and the screen are polarized, if you turn the screen or tilt your head it should become visible.

It's easier to control the brightness of a LED changing the frequency at which is lit on and off, so it's common. You can also see the intermittence swinging the thing fast with your hand. Well, if it's light enough to do it.

It can also happen that the power indicator light is a low power incandescent mini-bulb, powered by alternate current, so it flashes with the frequency of the current. 50Hz in Europe.
