This part of IEC 61747 is restricted to transmissive liquid crystal display-modules using either
segment, passive or active matrix and achromatic or colour type LCDs. Furthermore, the
transmissive modes of transflective LCD modules with backlights ON are comprised in this
document. An LCD module in combination with a touch-panel or a front-light-unit is excluded
from the scope because measurements are frequently inaccurate. Touch-panels or front-lightunits
are removed before measurement. Throughout the main body of this standard, an
integrated backlight is assumed to provide the illumination for the measurements. Deviations
from this (e.g. segmented displays without integrated backlights) may usually be handled in
the same way as display modules with integrated backlight, if an external backlight is
provided. However, in the case where one of the two situations should be handled differently,
this will be specifically stated.
