Paper Abstract

The contrast of Liquid Crystal Displays (LCD) was measured under both point source and diffuse illumination. It appears that diffuse lighting is more appropriate to the measurement of visual performance of reflective or transflective displays. The design of integrating spheres for the simulation of diffuse illumination is discussed. Concerning the representation of visual quantities as a function of viewing direction, the stereographic projection is more convenient than the standard pseudo polar plot.
