The object of this standard is to establish uniform preferred test methods with preferred values for stress levels for judging the mechanical properties of liquid crystal display devices. This first edition of IEC 61747-10-1 cancels and replaces Clauses 1 and 2 of the first edition of IEC 61747-5 published in 1998. This edition constitutes a technical revision.

These requirements are applicable when the detail specification is published (e.g. for standard product). This second edition of IEC 61747-2-1 cancels and replaces the first edition published in 1998, and constitutes a technical revision. The main changes from the previous edition are as follows: - several words and test conditions were added in Clause 7 and Clause 8; - the new edition was editorially changed according to the current ISO/IEC Directives - Part 2.

IEC 61747-4:2012 describes the essential ratings and characteristics of LCD cells and passive matrix monochrome liquid crystal display modules. It does not apply to active matrix LCD cells nor to multicolour cells. This edition includes the following significant technical changes with respect to the previous edition: - 2.1 and 3.1 of IEC 61747-4:1998 were deleted because these items are defined in IEC 61747-1; - 2.7.6, in 2.7, Supplementary information, of IEC 61747-4:1998 was deleted because the scope of this standard is about passive matrix monochrome liquid crystal display modules; - The item 'Gray scale: digital or analog' in 2.3.1 of IEC 61747-4:1998 was changed to 'Gray scale: number' because it is more accurate; - Contrast mode: light symbol on dark background ('LOD' or 'positive image') or dark symbol on light background ('DOL' or 'negative image') was introduced in this part of IEC 61747 to replace the description in 2.3.1 and 3.3.1 of IEC 61747-4:1998.

IEC 61747-30-1:2012 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. This first edition cancels and replaces IEC 61747-6 published in 2004. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: a) the document structure was brought in line with 61747-6-2; and b) various technical and editorial changes were made.
