What is a dead pixel and what are the levels of acceptance?
LCD displays are made up of millions of pixels (each one then made up of 3 sub-pixels red, blue and green). Each sub pixel has its own transistor so due to the complex nature of the technology, defects can occur in the manufacturing process. Unfortunately such defects cannot be repaired. An ISO standard has been established to regulate acceptable levels of defects and protect the consumer. ISO 13406-2 states how many pixel faults are acceptable before a display should be replaced. Morgans company policy is to work to the ISO standard.
