Pixel pitch refers to the distance between the centers of two adjacent pixels on a display screen or imaging sensor. It is typically measured in millimeters and is a crucial specification in determining the resolution and image quality of a display or camera. A smaller pixel pitch generally results in higher image clarity and detail, as more pixels are packed into a given area, allowing for finer detail to be represented. Pixel pitch is commonly found in specifications for various display technologies such as LED screens, LCD monitors, digital cameras, and other imaging devices.
