    Abstract - (Show below) - (Hide below)

    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.
