Re: flat screen monitor burn in

Tech-Archive recommends: Speed Up your PC by fixing your registry

LCD monitors are constructed very differently from CRT monitors. CRT monitors fire electron beams at phosphors on a glass surface, which can cause burn-in if the electron beams are firing at the same spot on the glass for a prolonged time. LCD monitors do not fire electron beams nor do they have phosphors, and consequently they do not suffer from burn in.

LCD monitors have their own unique problem, known as 'stuck' or 'dead' pixels. These are pixels that are stuck in a certain position, so they always display the same color. Dead pixels were more of a problem in the 'olden' days of LCD panels, say about three years ago. Improved manufacturing processes have greatly reduced the incidence of dead pixels.

Therefore, if you really do have an LCD monitor with an image permanently burned into it, your LCD panel is defective.

I posted a question about this awhile back, and the answers I got
implied that flat screen LCD monitors did not suffer from image burn
in. However, after taking that advice and not using a screen saver on a
couple of new monitors, I now have bad image burn in from a desktop
wall paper image. How can this be happening?

I had to cut and paste the original thread below, for some reason it
would not allow me to reply to that thread.....

I'm wondering if flat panel monitors are subject to image burn in the
same way CRT monitors are? I've learned the hard way that I needed to
use a screen saver on my CRT screens, but now I'm phasing in flat
screens and am wondering if I need to do the same.

As Carey told you: the answer is no, because LCDs use a different
technology altogether from CRTs.
