Stimulus Duration
Pixels are not on continuously during
a frame
In part this is necessary for clean motion
Typical CRT phosphors last about 4
msec. (Bridgeman, 1998)
On LCD and other technologies,
persistence is longer
Makes motion less clean but flicker less
noticeable
On clean motion:
observe lcd’s which are generally slower and thus on longer and recall the old green monochrome monitors on the early PCs
Bridgeman, B. (1998).
Durations of stimuli displayed on video display terminals: (n-1)/f+persitence.
