MULTI-TOUCH OPERATING PANEL
15 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 is eliminated by switching off the screen for a longer period of time or by
displaying dynamic content, serious cases of burn-in can lead to permanent damage to the
display.
This effect can have the following causes:
l
Operation without a screen saver
l
The same contents displayed over a longer time period (e.g. a single screen)
l
Operation at high environmental temperatures
l
Operation above specifications
The effect can be avoided/reduced by the following actions:
l
Using a screen saver
l
Deactivating the display when not in use (e.g. screen display black)
l
Continuously changing screen content (e.g. video)
INFORMATION
Deactivating the display backlighting only does not prevent Burn-In!
15.1 Screen Saver
The device has an integrated screen saver, which is activated by default and turns off the
screen after 60 minutes of inactivity. The screen can be reactivated with an input via the
touch screen or a USB operating device. The wait time for the screen saver can be
adjusted in the application via the HW class. This change is only active as long as the
device is running the application, in Reset mode, the 60-minute default setting is restored.
