IPS glow vs backlight bleed

IPS glow is an angle-dependent haze that appears mostly on dark backgrounds.

Backlight bleed behaves more like a fixed light leak from a corner or edge.

  • Many users call every dark-scene brightness problem bleed even when the panel is showing normal IPS behavior.

How to test it

Open a black or near-black full-screen image.

Dim the room lights.

  • Check the screen from your normal position and then from different angles.

When is it a problem?

A little glow is normal on many IPS panels.

A corner that stays obviously brighter in all conditions is more concerning.

  • Phone photos often exaggerate the effect.
