Progressive scan is a method of displaying images where each frame is drawn line by line in sequence. This means that all the lines of a single frame are shown at once, resulting in a smoother and clearer image, especially during fast motion. It is commonly used in modern video formats, such as HDTV and Blu-ray. In contrast to interlaced scanning, which displays alternating lines, progressive scan reduces flicker and improves overall picture quality. This technique is particularly beneficial for computer monitors and video games, where clarity and detail are essential for an optimal viewing experience.
