This part of IEC 61747 specifies the standard measurement conditions and measuring methods for determining the optical properties of transparent liquid crystal display modules which operate in a transmissive mode. More specifically, this document focuses on three particular aspects of the transparent properties, i. e. transmittance, haze, and image distortion.
