Backlight Bleeding

What is backlight bleeding?

Backlight bleeding refers to bright halos or bright areas on the monitor that are primarily visible when viewing dark content, such as in games or movies. The halos usually appear at the edge of the display and are caused by a different arrangement of liquid crystals in the display, which allow different amounts of light to pass through.

How does backlight bleeding occur?

IPS displays consist of several layers that are placed exactly on top of each other at different angles. Even the slightest deviation in layering can cause a slight pressure inside the display, which shifts the liquid crystals slightly. This allows more light to pass through in some places than in others. The resulting halos are called bleeding.

What can I do against backlight bleeding?

Unfortunately, there is not much you can do about this phenomenon. Even changing the display might not solve the problem of backlight bleeding. Therefore, sending in the device is unnecessary in most cases.

Schenker Technologies relies on high quality standards in the production of its products, which keep the impact for the user as low as possible. However, it is unfortunately not possible to completely exclude backlight bleeding for technical reasons.

Does backlight bleeding subside over time?

It happens that certain types of backlight bleeding diminish over time. Freshly produced displays are subject to a certain amount of mechanical stress, which decreases during the first weeks and months of use. This acclimation period does not yet occur in the warehouse, as it depends on the panel's operating temperature. An example of a decrease in backlight bleeding after 25 days is documented in this post on Reddit.
