- Abstract
- An experiment was carried out to compare the suitability in visual tasks between flat
and conventional (convex) cathode-ray tube (CRT) displays. The subjects performed
visual search tasks during 2-h for detecting target words among distracters presented
on the screen. The subjects′visual performance was evaluated with average time and
number of errors made to complete the tasks. Visual fatigue after the search tasks was
also evaluated in terms of degradations in accommodative power and subjective ratings.
Difference was not found in task time between the two displays, but flat CRT showed a
lower number of errors than conventional CRT. The difference in number of errors was
statistically significant at α=0.05. Although there was no difference between the
displays in degradations of accommodative power, results from the subjective ratings
showed that flat CRT yields less fatigue than conventional CRT. The results partially
support the hypothesis that panel convexity of CRT displays has a significant effect on
the performance and fatigue during visual tasks and thus flat CRT is the better display
than conventional one.
