Abstract
We compared the characteristics of state-of-the-art mobile display systems
based on reflective and transmissive liquid crystal displays (LCDs) and an
organic light-emitting display with respect to physical characterization
metrics and observer studies. Physical performance factors provided
information on the differences among display technologies. Observer studies
resulted in different system ranking between the task-based performance and
user-preference approaches. The results of the physical characterization and
preference study showed that the reflective LCD ranked lower. We also found
that ambient illumination played a lesser role than previously seen in
large-format workstation displays. The methodology developed in this study
provides an initial insight into the comparison of alternative technologies
for display of diagnostic images in small portable devices.
