Display “Burn-In” Effect
The “Burn-In” effect describes a pattern burned into the display after displaying the same
contents over a longer period of time (e.g. a single screen).
This effect is also described mostly as “image sticking”, “memory effect/sticking” or “ghost
image”. Here, a distinction is made between a temporary and permanent effect. While the
temporary effect fades after the screen has been turned off for some time or when dynamic
content is displayed, damage from the permanent effect is irreversible.
This effect can have the following causes:
•
Operation without a screen saver
•
The same contents displayed over a longer time period (e.g. a single screen)
•
Operation at high ambient temperatures
•
Operation above specifications
The effect can be avoided/reduced by the following actions:
•
Use of a screen saver with continuous content change (e.g. video)
•
ATTENTION: Switching off the backlight does not prevent this effect but only increases
the life of the backlight
