Glossary » flicker


in CRT displays, the screen is rapidly refreshed, generally 50-100 times per second. In between refreshes, phosphors dim, but the human eye will only perceive the average luminance provided that the refresh is frequent enough. Unfortunately, the periphery of our eyes is much more sensitive to flicker, and so we are likely to perceive flicker in screens placed to our sides, which may become a distraction and annoyance for some people.
