Flickerless Regeneration Rates for CRT Displays as a Function of Scan Order and Phosphor Persistence

Abstract

The effects of two variables on the regeneration rates required to prevent flicker on CRT displays were investigated in this computer-automated experiment. The two variables were the sequential order in which the display was scanned (e.g., horizontal, vertical, or pseudo-random scanning) and the persistence of the phosphor on the display. Twenty-one different scan orders and two phosphors (P-12 and P-38) were used. Results showed that flickerless regeneration rates depended principally upon phosphor persistence; scan order had only a minor influence. The main effect of random and pseudorandom scanning was to reduce the disturbing effects of display flicker when it did occur, rather than to reduce significantly the regeneration rate at which flicker did not occur. © 1970, Human Factors and Ergonomics Society.
