IEC 62977-2-11 Ed. 1.0 en:2023

This part of IEC 62977 specifies the local luminance and uniformity measurement methods of emissive displays.

The local luminance and uniformity measurement methods identify optical variations within the local block where over 500 emission pixels are regularly placed.
