Display Measurements. Measurement of Reflectance-Type Displays.

摘要

This report applies the Equation of Spencer and Gray to specify the reflectance of reflective-type displays. This reflectance specification uses both a diffuse component function and a specular component function to completely describe any reflecting surface. The particular display chosen to illustrate the use of this method of specifying reflectance was the Hughes' Liquid Crystal Matrix Display. This display is a matrix display and produces an image by electrically controlling the reflectance of each individual cell. In the appendix, a simplified example using this method of reflectance specification to evaluate a liquid crystal display optical system is given. (Author)
