Why is it bad to touch the screen on an HDTV?

Question

My dad just bought an HDTV and he spazzes out if anyone goes near the screen. He says touching it will ruin it. Is this true?

Answer 1

a lcd will break the crystals. a plasma i dont think it causes damage

Answer 2

The screen is made of heavy glass and just touching it will not damage it.   However, if you leave fingerprints and someone tries to clean them off that could cause a problem  There are special cleaners for LCD and plasma screens, and also instructions in the user manual.  If done correctly, the screen can be cleaned.   But it is better not to get it dirty in the first place.

Answer 3

I think gp4arts got negative rating for the last comment  "But it is better not to get it dirty in the first place."  Otherwise, gp4arts is correct.  

I have two HDTV, three analog TV, and two computer monitors that all attracts dust.  I'm sure a lot of people have the same experience. It is not like tossing dirt and dust at the screen.  Short of feather dusting every day,  it is impossible to keep the screens dust free. I rather not touch the screen at all.  The less you touch it the less likely to cause damages or scratches. I will only clean the screen when the dust can't be ignored.  

To respond to the question, gp4arts is correct.  Let Dad notice the dirty screen and he will clean it himself.

Answer 4

gp4arts got negative ratings for his answer? Wow, who did that and why? ^^ He / she is perfectly right. So, just to support his / her post:

As mentioned before: Touching the screen leaves fingerprints / traces of your skins natural oils / sebum and whatever else there may be. Cleaning it is possible, but even with special equipment for cleaning screens: Every cleaning process has an influence on the surfaces affected ... be it as minimal as possible. So to maximize the lifetime of your screen (or so to say: to minimize the disturbance of the tv picture by minimal defects of the surface of the screen) you're really better of not to touch it with anything.

Answer 5

no your dad is telling you a fib the only thing it will do is leave finger prints and for finger prints get a screen cleaner not windex or anything like that

Answer 6

It will ruin the whole thing if you press on it too hard. It will break the crystals. But just touching it will put smudges or prints on it, thats all.
