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 or IPS Glow?

Backlight bleeding and IPS Glow are 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 it occur?

This 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 and light leakage around the edges are what we refer to as Backlight Bleeding and IPS Glow.

At this current point, there is no possible way to eliminate these entirely, as it is considered a limitation of IPS panel technology. Note that IPS glow and backlight bleeds vary across different units of the TV, even if it’s the same model in question

How can I reduce these?

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

You may attempt the following to reduce the effect:

1. Lower the brightness of the display.
2. Ensure the environment is well-lit/ Adjust the brightness of the room by adding ambient lighting.
