Subpixel anomalies
From Applepedia
Subpixel anomalies are when a pixel on an LCD is broken.
[edit]
How many need to be broken to get it replaced?
According to a document leaked by ThinkSecret, Apple will replace your LCD if you have:
- More than 3 pixels stuck in a bright state
- More than 5 pixels stuck in a dark state
- A combination of more than 7 pixels stuck in a bright or dark state.
