Default CRT static electricity

This has been getting on my nerves for a while now (not the electricity). My computer CRT gives off no static shock at all, nor does any I’ve had, but every CRT TV I’ve had gives off static shocks and if you get some aluminium foil you can get a nice (and painful) arc especially (painful) when grounded.

Does anyone know why, is it just a conspiracy so everyone has to buy dusters because your TV attracts dust?

Dont know why but both have tvs always pick up static but my crt monitor never does. Could be the arial?

On a related note I was using my xbox with a hands free mike plugged in for online gaming and I wiped the tv screen, there was a cracking sound in my ear and a sharp pain

It could have something to do with the fact that TV screens still use interlaced technology whist CRTs for PC' are non interlaced

Possibly you get more charge on the screen with an interlaced mode - it's just a guess though.

Why is this in Against the Mainstream?

This site talks about the static electricity issue with CRTs, but makes no distinction between TVs and computer monitors except to say:

Quote:
As a footnote to all of this, many CRT monitor manufacturers are now coating the screens of their products with a metal film which serves to conduct the electrostatic charge away from the screen. No more ZAPS!
Maybe that's it?

I suppose a lot more people touch their computer screens than touch their TV screens, and that's why the computer folks decided to do something about it . . .

And why is that I wonder. Why do people insist on sticking their sticky little fingers on a computer screen? I hate a screen full of finger prints. Really hate it. Gotta clean them all the time. Keep your fingers away from the computer screen. You don't know where that crt has been.

Sorry, had to rant. :P

I don't tend to post questions in babbling like this because there is normally lots of conflicting idea's. Journal stuff I try and post on babbling unless it's ATM.

Also i'd think people would rather have static free TV's than monitors. I always have to use a wet cloth to dust my TV screen because a dry duster doesn't pick it up because of the charge on the TV screen. So I use a wet cloth and i have to clear the static first or i get a really nasty shock, especially if I'm doing the downstairs one. We have nice hard wood flooring with a big enough gaps in them to conduct the shock to the insulator (aluminium foiling) and as that's grounded by the radiators I can feel the nerves in my arm for about 10 minutes. So I refuse to dust till someone gets proper flooring

Anyone being shocked by the igniter spark on a gas cooker? That one feels like it stops your heart.

If you want some static fun, get yourself some clean-room sticky-mats. Pulling off the top one generates some serious charge - I get a nice, nasty shock when I open the door afterwards, on a dry morning like today. My hair stands up on end first, of course.

I know the casing on my Mac G5 is pretty prone to static shocks as well.
Manys the time I've gone to change a cd and gotten a zap.

Do you have an office chair with wheels? does it roll around on a carpet?
It's the best way to build up a charge.
