This article sketches the winding path of the art of measurement of LC‐display contrast and other visual properties versus viewing direction from the beginnings of LCD‐manufacturing in the 1970s until today. It describes two methods of directional scanning: conoscopy—an optical approach without moving parts—and gonioscopy, the motorized scanning of the range of directions of interest, and introduces their features and limitations and a range of instrumental implementations.
