Flicker is a visible fading between cycles displayed on which type of displays, especially the refresh interval on Cathode ray tube televisions and computer monitors as well as Plasma based computer screens and/or Television (TV) is a telecommunication medium used for transmitting moving images in monochrome (black and white), or in color, and in two or three dimensions and sound?
Flicker (screen) Flicker is a visible fading between cycles displayed on video displays, especially the refresh interval on Cathode ray tube televisions and computer monitors as well as Plasma based computer screens and/or TVs. Flicker occurs on CRTs when they are driven at a low refresh rate, allowing the brightness to drop for time intervals sufficiently long to be noticed by a human eye – see persistence of vision and flicker fusion threshold. For most devices, the screen's phosphors quickly lose their excitation between sweeps of the electron gun, and the afterglow is unable to fill such gaps – see phosphor persistence. A similar effect occurs in PDPs during their refresh cycles.
Carrier wave In telecommunications, a carrier wave, carrier signal, or just carrier, is a waveform (usually sinusoidal) that is modulated (modified) with an input signal for the purpose of conveying information. This carrier wave usually has a much higher frequency than the input signal does. The purpose of the carrier is usually either to transmit the information through space as an electromagnetic wave (as in radio communication), or to allow several carriers at different frequencies to share a common physical transmission medium by frequency division multiplexing (as, for example, a cable television system). The term is also used for an unmodulated emission in the absence of any modulating signal.
