7.4 Preventing screen burn-in on LCD/TFT displays
Screen burn-in (afterimages, display memory effect, image retention or image sticking) occurs on LCD/TFT displays
if a static image is displayed for a prolonged period of time. This static screen content causes the build-up of
parasitic capacitances within the LCD components that prevent liquid crystal molecules from returning to their
original state. This condition is unpredictable and can depend on the following factors:
•
Type of image displayed
•
Color composition of the image
•
Length of time that the image is displayed
•
Ambient temperature
7.4.1 How can this be avoided?
There is no perfect solution. There are ways to significantly reduce this effect, however:
•
Avoid static images or screen content.
•
Use non-static screensavers when the display is not in use.
•
Frequent picture change
•
Turn off the display when not in use.
Turning off the backlight does not help prevent screen burn-in.
