Paper Abstract

We compare the image quality characteristics of state-of-the-art mobile display systems based on different types of liquid crystal and organic light-emitting materials with respect to luminance and color, viewing angle, resolution, temporal response, and reflectance. The results for a reflective liquid crystal display suggest that the changes in angular contrast and color shifts are more severe than for other LCDs, particularly for medical LCDs, where no color or grayscale inversion is present within the entire hemisphere of viewing directions. A prototype light-emitting device showed a wide viewing angle and large small-spot contrast. Display reflectance and resolution were affected by the additional touch-screen coatings. The methodology developed provides a framework for the comparison of alternative technologies for display of diagnostic images in small portable devices.
