Why AMOLED Dead Pixels Are Different
AMOLED (Active Matrix Organic Light Emitting Diode) pixels generate their own light — there is no backlight. Each pixel contains three sub-pixels (red, green, blue) made of organic material that emits light when current passes through it.
- True dead pixel (AMOLED): The organic material has degraded or the transistor has failed. The sub-pixel is permanently dark. Cannot be fixed by software.
- Stuck sub-pixel (AMOLED): The transistor is stuck in an on state. The pixel emits light at one colour and cannot turn off. May respond to rapid cycling.
- Burn-in: Organic material in high-use areas degrades faster, leaving a ghost image. The pixel still functions but at reduced efficiency. Not the same as a dead pixel.
How to Test an AMOLED Screen for Dead Pixels
- Black screen: Look for bright or coloured dots (stuck pixels).
- White screen: Look for black dots (true dead pixels).
- 50% grey: Look for ghost images or retention (burn-in, not dead pixels).
- Red, green, blue: Wrong-colour dots indicate stuck sub-pixels.
Fix Dead Pixel AMOLED — Does It Work?
Rapid colour cycling can revive stuck sub-pixels on AMOLED — the method works by forcing the pixel transistor to switch rapidly, which can break it out of the stuck state. Run the fix tool for 10–20 minutes.
True dead pixels on AMOLED cannot be fixed this way — the organic emitter has failed at the hardware level. The only fix is screen replacement.
AMOLED vs LCD — Which Gets More Dead Pixels?
| Factor | AMOLED | LCD |
|---|---|---|
| True dead pixels | Less common | More common (backlight failure) |
| Stuck pixels | More common | Less common |
| Burn-in | Yes (after years) | No (image retention is temporary) |
| Impact dead pixels | Common | Common |
| Self-fixable | Stuck pixels: sometimes | LCD: rarely |
Frequently Asked Questions
What does a dead pixel look like on AMOLED?
A true dead pixel on AMOLED is completely black — the organic emitter has failed and produces no light. It is most visible on a bright white background. A stuck pixel on AMOLED is a bright coloured dot (often red, green, or blue) that does not turn off — most visible on a black background.
Are dead pixels common on AMOLED?
True dead pixels are less common on AMOLED than on LCD because AMOLED pixels emit their own light — there is no backlight that can cause mass dead pixels. However, stuck sub-pixels are more common on AMOLED than on LCD.
Can AMOLED dead pixels be fixed?
Rapid colour cycling (the fix tool) can revive stuck sub-pixels on AMOLED. True dead pixels — where the organic emitter has physically failed — cannot be fixed by software. These require screen replacement.
Is AMOLED burn-in the same as a dead pixel?
No. Burn-in (image retention) is a ghost of a previously static image that appears when viewing a different background. The affected area still functions — it just shows residual colour. A dead pixel is a permanent hardware failure that stays black on all colours.
How do I tell burn-in from a dead pixel on AMOLED?
Test on a white screen: a dead pixel stays black. Burn-in shows a faint ghost image — it may look grey or slightly coloured on white. Also test on 50% grey — burn-in is most visible on mid-grey. Dead pixels are not visible on grey if the grey is close to the grey they have failed at.
Which is better for dead pixels — AMOLED or LCD?
AMOLED has fewer true dead pixels but more stuck sub-pixel issues. LCD has a higher risk of dead pixels (especially from backlight damage) but rarely gets burn-in. For phone use, AMOLED is generally more reliable for pixel failure overall.
