IEC 61947-1:2002规定了测量和记录具有固定分辨率投影仪的电子投影系统的关键性能参数的要求，其中光源和投影/放大光学器件是系统的组成部分（即单个像素光源或矩阵显示器，如液晶、DMD、等离子或电致发光面板）。它也适用于LCD面板或其他固定分辨率成像设备本身，这些设备与高架投影仪一起使用。该双语版本（2013-02）对应于2002年至2008年出版的单语英语版本。

IEC 61947-1:2002 specifies requirements for measuring and documenting key performance parameters for electronic projection systems with fixed resolution projectors in which the light source and projection/magnification optics are an integral part of the system (i.e. individual pixel light sources or matrix displays such as liquid crystal, DMD, plasma, or electroluminescent panels). It also applies to LCD panels or other fixed resolution imaging devices themselves that are used with overhead projectors. This bilingual version (2013-02) corresponds to the monolingual English version, published in 2002-08.
