SAE J 1757/1:2021-08-24

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.
