iPhone 11 Dead Pixel — LCD vs OLED Testing

The iPhone 11 and 11 Pro use different display technologies, which changes how dead pixels appear. The standard iPhone 11 uses Liquid Retina LCD — a dead pixel appears as a permanently black dot on all colours. The 11 Pro and 11 Pro Max use OLED (Super Retina XDR) — on these models, a stuck sub-pixel appears as a bright coloured dot on a black background, while a true dead pixel stays black.

The iPhone dead pixel test works for all three models. On the LCD iPhone 11, also check for backlight bleed — uneven brightness near the edges, which is a different issue from dead pixels.

Repair Cost Without Warranty

All iPhone X through 11 models are well outside their standard warranty. Screen repair costs vary:

  • iPhone X / XS / XS Max: $150–$280 (Apple or third-party)
  • iPhone XR: $130–$200
  • iPhone 11: $130–$200
  • iPhone 11 Pro / Pro Max: $180–$280

For models this old, third-party repair or trade-in often makes more economic sense than an Apple repair.
