Scope
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. The present revision does not address the usage of polarized sunglasses.
Rationale
A new line was introduced in Table 1A and clarifications related to reflections from white cloth in critical light source cone area (CLSC). A new image and method were added for cross talk luminance non-uniformity (LNU) determination.

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.
