Contrast ratio意思

"Contrast ratio" is a term used to describe the difference between the brightest color (white) and the darkest color (black) that a display device can produce. It is an important factor in determining the quality of an image displayed on a screen. A higher contrast ratio means that the device can produce darker blacks and brighter whites, which results in a more vivid and detailed image. Contrast ratio is often used to compare the quality of different display devices, such as televisions, computer monitors, and smartphones.
