8.2 User tips for increasing the service life of the display

8.2.1 Backlight

The service life of the backlight is specified by its "half-brightness time". An operating time of 50,000 hours would
mean that the display brightness would still be 50% after this time.

8.2.1.1 How can the service life of backlights be extended?

• Set the display brightness to the lowest value comfortable for the eyes.
• Use dark images.
• Reducing the brightness by 50% can increase the half-brightness time by approximately 50%.

8.2.2 Image persistence

Image persistence refers to the "burning in" of a static image on a display after being displayed for a long time. It
does not only occur with static images, however. Image persistence is also referred to in the technical literature as
screen burn-in, image retention, memory effect, memory sticking or ghost image.
There are 2 different types:
• Area type: This type can be seen in a dark gray image. The effect disappears if the display is switched
off for a long time.
• Line type: This can result in permanent damage.

8.2.2.1 What causes image persistence?

• Static images
• No screensaver
• Sharp transitions in contrast (e.g. black/white)
• High ambient temperatures
• Operation outside of specifications

8.2.2.2 How can image persistence be reduced?

• Switch continuously between static and dynamic images.
• Prevent excessive differences in brightness between foreground and background elements.
• Use colors with similar brightness.
• Use complementary colors for subsequent images.
• Use screensavers.

8.3 Pixel errors

Information:
Displays can contain faulty pixels (pixel errors) due to the manufacturing process. They are not
grounds for initiating a complaint or warranty claim.
