Abstract

Flat panel displays can exhibit undesirable visual effects previously unseen with other display devices. One such effect is the presence of bright bands, or multiple images, surrounding the mirror image of a small, intense light source, like the sun. These bands and multiple images have been identified as diffraction patterns caused by the display pixels. With some displays, the diffraction patterns are obvious, while others exhibit minimal diffraction. The appearance of a pattern varies considerably between display designs, while remaining consistent between displays of similar design and construction. Specific display design features and materials are responsible for many pattern characteristics. If the pattern is very bright, information presented by the display may be obscured. This presents obvious problems when the display must be read accurately and quickly, as in avionics or vehicle applications. In order to use flat panel displays effectively in these environments, a means must be found to control or eliminate the bands. The purpose of this paper is to present an overview of the characteristics, causes, measurements, and strategies for prevention of diffraction bands on display devices.
