Abstract
This study was conducted to evaluate task performance and subjective preference for two color displays with differing image generation technologies, the standard cathode ray tube shadow mask display and the newer liquid crystal/cathode ray tube display. Six subjects performed three different information processing tasks using each of the two color display technologies and expressed their display preference via evaluation questionnaires. Ambient illumination measurements were obtained to determine optimal conditions for each display. Performance data were obtained as errors per unit task quantity for each of the task types. Subjective evaluations consisted of 5-interval bipolar adjective scales and a forced choice rating. Parametric analyses of the performance measures indicated minor differences between the two display technologies, while nonparametric analyses of the subjective data indicated a preference for the liquid crystal display technology.
