Abstract
We present and validate an easy-to-setup approach to measure the reflection properties of displays. It is based on a wide field of view conoscopic lens in conjunction with an orientation detection algorithm. Using this approach, we can measure not only the specular, haze, and Lambertian components of display reflection but also the diffractive component. We then investigate the fundamental dependencies of this fourth reflection component through a series of measurements using a variable aperture source and an LC and OLED display. Through these experiments, we can show that the diffractive component scales linearly with the light source's luminance and depends on the angular subtense of the light source.
期刊介绍：
The Journal of the Society for Information Display publishes original works dealing with the theory and practice of information display. Coverage includes materials, devices and systems; the underlying chemistry, physics, physiology and psychology; measurement techniques, manufacturing technologies; and all aspects of the interaction between equipment and its users. Review articles are also published in all of these areas. Occasional special issues or sections consist of collections of papers on specific topical areas or collections of full length papers based in part on oral or poster presentations given at SID sponsored conferences.
