In the research carried out, a display environment containing both a static and a dynamic section was designed to investigate the effects of the design factors of the dynamic display on users' e-reading comprehension performance in the static and dynamic sections. The dynamic display factors include:1.Display types (leading, RSVP, and flash),2.Speeds [140, 195, 250, and 305 words per minute (wpm)], and3.Text/background colour-combinations (16 colour-combination settings).Experimental results showed that subjects' comprehension on static display mode was not significantly affected by any of the dynamic display factors. Nevertheless, all the dynamic display factors had significant effects on subjects' comprehension of the information in the dynamic display section. With the leading display type, subjects performed best at 195 wpm. When the display type was RSVP or flash, subjects performed best at 140 wpm and worst at both 250 and 305 wpm. The effects of the text/background colour-combinations were that subjects performed the best comprehension at the dynamic display section with the same text/background colour-combinations of the static display sections. The dynamic display section with the same text/background colours but with opposite display polarities of the static display sections was second. Subjects performed the worst comprehension when the text/background colours of the dynamic display section were completely different from that of the static display section.
