Dead Pixel A dead pixel is a malfunctioning pixel on a digital camera sensor or electronic display that does not properly respond to signals and remains permanently "stuck" in one state. Dead pixels can appear as small, bright dots or dark spots in images or on screens, depending on whether they are stuck in an "on" or "off" position.
Dead pixels can occur due to manufacturing defects, physical damage, or age-related deterioration of the sensor or display. While dead pixels are often negligible when they are few in number, they can become noticeable and distracting when they accumulate or appear in prominent areas of an image or display. Dead pixels are typically covered under warranty for electronic devices, and manufacturers may offer repair or replacement for affected units. |
