Evaluation of a Portable Computer With a Wireless Transflective Display for Use in Avionics Cockpits

Abstract

Display technologies are being developed to enable commercial products like electronic paper, electronic tablets, and wireless information appliances. These products offer an opportunity for evaluation to determine their suitability for use in the cockpit environment and other defense applications. It is important to evaluate the maturity of a new technology alternative, in this case a transflective active matrix liquid crystal display (AMLCD), before considering its use in critical applications. This paper reports the results of an initial evaluation of a portable computer with a light-weight wireless transflective display. The display is characterized in a dark ambient and then again when illuminated with simulated full sunlight in terms of its luminance and contrast ratio. The contrast ratio values are evaluated to determine the optimum viewing angles and conditions. Also, an operator performance study was conducted to assess display legibility.
