Monitor burn in

by TheChas In reply to Monitor burn in

Not exactly.

Theoretically, a LCD monitor should have as clear an image 10 years from now as it has today.

The burn-in effect on CRT monitors comes from burring away part of the phosphor coating on the back surface of the screen.

A LCD monitor will still suffer the effects of aging. Many of which will be unrelated to the on-time for the LCD.

On an LCD monitor, the pixels either light or do not light.
Over time, a few pixels will burn out.
The burn out comes from a combination of manufacturing tolerances and the amount of time the pixel is at full brightness.

Another thing that will happen is that the bulbs for the back light will loose luminosity, and the display will get darker.

Scratches and impact damage to the face of a LCD display will show up as distortion or discoloration over time.

Some clear plastics discolor over time, and that can cause a dim or dingy display.
Smoking and other chemical fumes near a LCD will hasten this degradation.

So, no you will not see a shadow image on the screen after years of the same image being displayed. Still, there will be a degradation in the display as it ages.

Hope this helps.

Good answer by Chas and well detailed. NO the LCD monitor will not suffer burn marks, so the only thing a screen saver will do is look pretty. The cathode gun (Cathode Ray,)inside the picture tube, shooting electrons on the phosphor painted behind and on the glass screen you look at, is what causes burn marks over time. No such animal in an LCD monitor.
