Backlight Bleeding: What It Is and How to Reduce It

Backlight bleeding is a common occurrence in IPS panels and are not exclusive to PRISM+products and does not indicate a defect, neither is it a manufacturing issue with the display.

This effect should not be visible during regular use, with sufficient lighting in the room.

 

What is Backlight Bleeding?

Backlight bleeding is most obvious when viewing a panel's dark screen, in a low light environment. This will manifest as lights appearing along the edge or corner of the display.

 

 Why does Backlight Bleeding occur?

Backlight Bleeding is more common in IPS panels due to the Liquid Crystal alignment that is used. The displays work in a way where there are multiple layers aligned at different angles.

Deviations in such angles and layering can cause pressure, in turn displacing the liquid crystals under the panel. The displacement of the liquid crystals refracts more or less light, causing an uneven brightness. 

This uneven brightness is what we refer to as Backlight Bleeding.

At this current point, there is no possible way to eliminate Backlight Bleed entirely, as this is considered a limitation of IPS panel technology.

However, there is another way to go around this issue. 


How can I reduce Backlight Bleeding?

There is no way to negate backlight bleeding completely, but what you can do is attempt to reduce its degree of visibility.

You may attempt the following to reduce the backlight bleed:

1. Lower the brightness of the display.
2. Ensure the environment is more well lit/ Adjust the brightness of the room.

If the above does not help, and you are still able to see bright lights along the corner when the display is actively displaying a bright screen, please contact us here.
