1 Scope
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-light-units
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.
