WebJan 6, 2010 · Phosphor trails are visible when fast movement of high contrast edges (black next to while) happens. This happened on CRTs too since they also use phosphor and the light emitted takes time to "decay" after the sub-pixel is turned off. In Panasonic plasmas the green phosphor decays more slowly that the others so you may see green trails. WebPhosphor persistence of CRT monitor. Phosphor persistence lasts approximately 6.4 ms after peak amplitude. Data are averages of 100 trials of single frame presentations of pure white light...
