This part of IEC 61747 gives details of the quality assessment procedures, the inspection
requirements, screening sequences, sampling requirements, and test and measurement
procedures required for the assessment of liquid crystal display modules.
This standard is restricted to reflective liquid crystal display-modules using either segment,
passive or active matrix and a-chromatic or colour type LCDs (see Note). Furthermore, the
reflective modes of transflective LCD modules with backlights OFF and reflective LCD
modules of front light type without its front-light-unit, are comprised in this standard. A
reflective LCD module with combination of a touch-key-panel or a front-light-unit is out of the
scope of this standard, because its measurements are frequently inaccurate. Its touch-keypanel
or front-light-unit should be removed before it can be included in this scope.
The purpose of this standard is to indicate and list the procedure-dependent parameters and
to prescribe the specific methods and conditions that are to be used for their uniform
numerical determination.
