This Standard was technically approved by the Flat Panel Display – Materials & Components Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on August 31, 2016. Available at www.semiviews.org and www.semi.org in January 2017; originally published July 2004; previously published July 2010.
Markers on FPD polarizing films, originally used for indicating optical direction of the films, have expanded the variety of products, such as identification for both sides of films, and for equipment. This also complicated the variety of shapes and colors for markers.
This Standard establishes specification for unifying markers used for indicating direction of FPD polarizing films.
This Specification may be applied to manufacturing process, quality control, and designing of Liquid Crystal Display (LCD) panel.
