ICDM

Premier Display Measurement Standard Available  

The International Committee for Display Metrology (ICDM) and the Society for Information Display (SID) released the Information Display Measurements Standard (IDMS) in 2012. The IDMS is the "Go-To" document for standard measurement procedures to quantify electronic display characteristics and qualities. It is the culmination of years of effort by engineers and scientists across dozens of organizations to codify the science of display measurement, explain some of the difficulties associated with making measurements, and offer solutions to help make the measurements properly. The IDMS has benefited from the expertise of display metrologists, electrical, mechanical, software and optical engineers, physicists, vision scientists, and many other display-related disciplines. The ICDM is currently developing v1.1, which will update and add new content to the v1 release.

To promote the spread and use of the measurement procedures and techniques within the display community, an electronic version of the IDMS is freely available. It is unprecedented in the display community that a piece of work of this scope and depth be distributed at no charge. This decision follows the philosophy of the ICDM and SID, which is to provide the standard to as wide of an audience as possible to help establish the techniques within the document as the universal choice for display measurements. SID and the ICDM expect this document to continue to evolve over time, with updates, supplemental files, and other value-added content to follow.

The IDMS features the following:

• Self-contained measurement procedures that are clear and easy to use
• A library of commonly used and newly developed display measurements
• Dozens of new display measurements for current and future displays
• Adaptability - allows a variety of equipment for measurements
• Tutorials and other supplemental sections included
• Includes diagnostics, cautions and useful hints

Benefits of using the IDMS include:

• Lower costs: consume less time and money due to unambiguous definitions of measurement methods
• Reduce development lead times by using standardized metrics
• Provide a common language to reduce risk of disagreements regarding performance
• Increase customer satisfaction by having more accurate, reliable, and repeatable performance characterizations
• Convenience: provide all measurement procedures and auxiliary information under a single cover

Former ICDM Chair, Joe Miseli, stated "The IDMS is the first standard from the ICDM and SID. It is a defining work for evaluating displays and is the most comprehensive display measurement and metrology standard yet produced. It provides a full set of common and more specialized display measurement procedures to characterize display performance. It also includes new and innovative measurements never before standardized for characterizing modern displays, as well as many references to clarify and expand upon metrology foundations and techniques. It builds upon the tremendous amount of work of many, especially the Editor-in-Chief, Ed Kelley, a former NIST physicist and one of the foremost metrologists in the display industry today. The IDMS is written in plain English with abundant use of graphics and examples that makes it simple to use and so can be widely applied throughout the display industry. It is all-inclusive so that everything one needs is available in a single volume."

Former SID President, Brian Berkeley, stated, "SID is proud to [make available] the first release of the IDMS. This landmark standard is the culmination of untold hours of effort on the part of contributors representing a broad cross-section of the display field. The IDMS is the single most significant display measurement standard to be released in more than 10 years. Working under the auspices of SID, and with the cooperation of the Video Electronics Standards Association (VESA), the ICDM has created a valuable standard that truly advances display measurement science. The IDMS will enable and promote consistency in the characterization and reporting of critical display performance parameters. Considering the rapid pace of innovation and advances in display science over the past decade, the IDMS meets a tremendous need for the display industry. SID congratulates and extends its thanks to all of the ICDM members for their profound contribution."

The IDMS is the follow-up to the Flat Panel Display Measurements Standard (version 2.0), used extensively by the industry since its publication by the VESA in 2001. The IDMS does not set performance standards, but gives guidance about how to measure displays. This will allow component suppliers, display manufacturers and customers to clearly communicate, understand and agree with the measurement and characterization methods upon which performance standards are based.

The IDMS is a display measurement and metrology standard to help evaluate displays by providing many measurements, techniques for subjective evaluation, and appendices with helpful references. It may be downloaded without charge provided the user accepts and agrees to the Terms of the Society for Information Display End User License Agreement.

IDMS Revision Record

The errata listed here are changes to sections of the IDMS to correct errors which were found on a per-section basis by users of the document or to add information to help do the measurements and/or evaluation. Most were reviewed internally, and then the ICDM membership was given access to the errata before they were posted here, to help verify their accuracy and to help assure no one had any issues or concerns about them. Some of them were voted to be accepted by ICDM members at Display Week.

Test Pattern Downloads

The ICDM Test Patterns are in the Public Domain.

The ICDM provides display test patterns which can be used for testing with the IDMS1 (Information Display Measurement Standard) or for general display performance measurements or evaluation.

These patterns are native format patterns for a number of display formats (format being the pixel array of the display, sometimes referenced as resolution). You can freely download them for your use. Please be sure to give recognition to the ICDM for making these patterns available to all.

These test patterns are in the public domain presented by the ICDM. They were initially developed by Ed Kelley when he was with NIST, with contributions from Joe Miseli. Thanks also to Michael H. Brill for the concept of the Color Inversion Pattern (CINV01_...). Although you can use them freely, please always give mention to the ICDM for providing them and keep the ICDM name with them in distribution.

We plan to add more to these pattern sets, so be sure check back from time to time. The dash number indicates the revision level of the pattern. Each successive update to the test pattern sets will be seen as an increment to the version number in the title. For example, the current bitmapped test pattern file ICDM-00_1920x1080.zip will increment to be ICDM-01_1920x1080.zip when the next version is available.

On this site we plan to include further test patterns to support the ICDM standard (IDMS), reportingtemplates, and other utilities to help you use the IDMS.

Measurement Report Template Downloads

The ICDM Measurement Report Templates are in the Public Domain.

The ICDM provides display measurement report templates which can be used for recording the results of testing with the IDMS1 (Information Display Measurement Standard). You can freely download them for your use. Please be sure to give recognition to the ICDM for making these templates available to all.

We plan to add more to this set of report templates, so be sure check back from time to time.
