Abstract

Commonly used methods for measuring reflections from the surface of an electronic display are often subject to large errors and ignore critical aspects of reflection from modern-day displays. This is largely due to an oversimplificaiton of the reflection process, namely, considering reflection to be a simple combination of diffuse (Lambertian) and regular specular reflections. The Flat Panel Laboratory at NIST is developing an alternative method that accurately predicts the reflected luminance from a flat panel display from known lighting conditions using the bidirecitonal reflectance distribution function (BRDF) of the display. The BRDF reflection model employed separates the reflection into three components: diffuse (or Lambertian), specular, and haze. The simplifications made and methods to obtain the required coefficients are discussed. Calculated values for the reflected luminances are compared to measured values for several lighting conditions.
