Contrast ratio is the ratio between the luminance of a full-white pixel and a full-black pixel on a display. It measures how much the display can differentiate the brightest and darkest parts of an image. For example, a 1000:1 contrast ratio means the white level is 1000 times brighter than the black level.
A higher contrast ratio produces deeper blacks and more vivid whites and grays, enhancing image sharpness and readability, especially in challenging lighting. This is a key parameter for high-quality displays used in medical, industrial, and digital signage applications. Note that measured contrast can differ from perceived contrast depending on viewing angle, panel technology, and coatings.
