The scope of this SAE Standard is to provide methods to determine display optical performance in all typical automotive ambient light illumination - with focus on High Ambient Contrast Ratio, which is critical for display legibility in a sunshine environment. It covers indoor measurements and simulated outdoor lighting.
It is not the scope of this document to set threshold values for automotive compliance. However some recommended values are presented for reference.
A new method was added to calculate the contrast in high ambient illumination based on scalable illumination data, it may be applicable to in vehicle white shirt / skirt reflections.

Vehicular Flat Panel Display Standards Committee
SAE J1757 objective is to define a consistent terminology and metrology for vehicular Flat Panel Displays (FPD). It will allow the user to measure the automotive compliance of the FPD (and any visual source of information).
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
