Dead pixels — small black, white, or coloured dots that remain stuck on screen regardless of what is displayed — and dark spots are persistent visual defects that affect both the usability and resale value of your phone. Pro-Logic Technologies deals with these faults regularly and can restore your display to a clean, spot-free condition.
Understanding Dead and Stuck Pixels
A pixel is the smallest unit of your display. Each pixel contains red, green, and blue sub-pixels that combine to produce every colour you see. When a pixel fails:
- Dead pixel — the pixel receives no power and appears permanently black.
- Stuck pixel — the pixel is locked on one colour (often red, green, or white) and cannot change.
- Dark spot — a cluster of dead or damaged pixels, often caused by physical pressure or impact, appearing as a dark patch rather than a single dot.
Common Causes
- Physical pressure or impact — pressing the screen hard, bending the phone, or dropping it can crush pixel cells beneath the surface.
- Manufacturing defect — a small number of dead pixels at point of manufacture is technically within tolerance for some manufacturers, though frustrating for users.
- Display cable damage — a partially failing display connection can cause pixel clusters to drop out.
- Age — older LCD panels gradually develop pixel failures as backlighting and liquid crystal layers degrade.
Can Dead Pixels Be Fixed Without Replacement?
Stuck pixels sometimes respond to pixel-cycling techniques — rapidly cycling through colours at the affected area — but this is only effective in a narrow set of cases and offers no guarantee. Truly dead pixels and dark spots caused by physical damage cannot be fixed without replacing the display assembly. We are transparent about this from the outset.
Our Repair Process
We replace the display assembly with a quality panel suited to your phone model. Before handing the phone back, we inspect the new screen under a white background at full brightness to confirm zero dead pixels or defects on the replacement panel. We do not fit screens with pre-existing defects — a quality check that some cheaper repair shops skip.
Dark spots and dead pixels are permanent without professional intervention. Visit Pro-Logic Technologies for a clean, defect-free display replacement.
