Light Wreaks Havoc with Automotive Display Standards
Optimizing vehicular flat panel displays depends greatly on developing standards
for measuring the ambient light that strikes them.
by Silviu Pala, Denso International America
The display that a driver sees inside a vehicle differs vastly from one car model to the next. Display standards — in terms of luminance, legibility, contrast, font size and more — are of concern to automakers.
A group with the Society of Automotive Engineers (SAE), in collaboration with the International Standard Organization, the National Institute of Standards and Technology (NIST) and the Society for Information Display, has been working since 1998 on the Standard Metrology for Vehicular Displays — Optical Performance (SAE J1757/1) for display legibility. The goal is to provide methods to determine the optical performance of vehicular displays in all typical lighting conditions...
