Modern smartphone displays come with high resolutions and millions of pixels working together to produce sharp images. However, two common issues often experienced by users are dead pixels and stuck pixels. At first glance, they may look similar since both appear as tiny dots on the screen, but they have important differences.
What Is a Dead Pixel?
A dead pixel is a spot on the screen that no longer functions. It cannot display light or color, usually appearing as a permanent black dot. In some cases, it may look white or gray, depending on the type of damage.
Nature: permanent and cannot be fixed by software.
Common causes: manufacturing defects, damage to the LCD/AMOLED panel, or aging screens.
Solution: usually requires replacing the LCD/AMOLED display.
What Is a Stuck Pixel?
Unlike a dead pixel, a stuck pixel still lights up but gets stuck on one color, such as red, green, or blue. That’s why stuck pixels appear as bright-colored dots on the screen.
Nature: temporary and sometimes repairable.
Common causes: electrical flow disruption in sub-pixels, or prolonged intensive use.
Solution: some cases can be resolved using pixel fixer apps, flashing rapid color patterns, or gently massaging the screen around the pixel area.
How to Tell the Difference Between Dead and Stuck Pixels
Dead Pixel: dark (black/white), permanent, does not change color.
Stuck Pixel: bright (red, green, or blue), may disappear on its own or be repairable.
Conclusion
Although both appear as small dots on the screen, dead pixels and stuck pixels are significantly different. Dead pixels are permanent and require screen replacement, while stuck pixels may be temporary and sometimes fixable.
