MT 61747 - TC 110/MT 61747

IEC 61747-30-3:2019(E) applies to transmissive type active matrix liquid crystal displays.
This document defines general procedures for quality evaluation related to the motion performance of transmissive thin film transistor (TFT) LCDs. It defines artefacts in the moving image and methods for motion artefact measurement.
NOTE Motion blur measurement methods and analysis methods introduced in this document are not universal tools for all the different LCD motion enhancement technologies due to their complexity. Users’ attention is drawn to this fact.
This first edition cancels and replaces the first edition of IEC 61747-6-3 published in 2011. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
a) added test positions and areas;
b) revised standard measuring conditions;
c) added calculation of the standard deviation of the line-spread function of the eye;
d) added requirements for high speed camera;
e) changed “LCDs” to “transmissive TFT LCDs” in Clause 1.

IEC 61747-40-1:2019 is available as IEC 61747-40-1:2019 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 61747-40-1:2019 provides mechanical performance testing guidelines for cover glass used in electronic flat panel displays in mobile devices. This document focuses on key mechanical testing performance parameters and covers mainly strength and damage resistance attributes. The test methods focus on the cover glass level testing only. This edition includes the following significant technical changes with respect to the previous edition:
- withdrawal of test methods unsuitable for mobile display cover,
- revision of test methods based on newly developed market relevance,
- addition of test method for abraded strength,
- addition of explanations about the relevance between the test methods and the fracture mode, and
- revision of terms and definitions.
