How can pixel defects be recognized?

The LCD panel consists of numerous pixels. The larger the size of the panel, the more pixels and the greater the chance that some will be defective and remain fully on/off or partially active. It is difficult to manufacture a large panel with zero defects using current LCD manufacturing technology. These defective pixels can usually be recognized as constant white/dark/colored areas on the screen.
