Rainbow effect screen protector
A rainbow or oil-slick effect on a screen protector is Newton's rings: the protector's adhesive is not fully bonded to the glass, or a wet-applied protector has liquid trapped, so light interferes between the two surfaces.
Test it now
Full-screen white; press gently beside the rings — they shift. Peel one corner of the protector: the rings vanish.
What it is
A rainbow or oil-slick effect on a screen protector is Newton's rings: the protector's adhesive is not fully bonded to the glass, or a wet-applied protector has liquid trapped, so light interferes between the two surfaces. It moves when you press near it. Real screen damage never moves.
Can it be fixed?
Yes. Peel, clean both surfaces with an alcohol wipe, refit pressing from the centre out; if it returns, replace the protector.
What to do
- Press beside the rings — moving = protector.
- Peel, clean, refit from the centre out.
- Wet-applied protectors: give them 24 hours.
- Returns again: replace the protector.

Warranty
Most makers replace a panel under warranty for physical panel faults that are not accidental damage; pressure marks, cracks and liquid damage are treated as accidental and are not covered. For dead pixels, each brand has a threshold (typically 3–5 bright or 5–8 dark pixels on a laptop; Dell's premium-panel guarantee replaces at one bright pixel).
