SEMI D50 - Test Method for Surface Hardness of FPD Polarizing Film
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 December 4, 2015. Available at www.semiviews.org and www.semi.org in March 2016; originally published July 2007.
This Specification defines the procedural guideline for measuring the surface hardness of a film and other components for Flat Panel Display (FPD) excluding glass. These procedures are applicable to manufacturing, quality control, and development work.
This Specification clarifies the differences when evaluating films and other components and its materials, using ISO 15184, Paint and Vanishes – Determination of Film Hardness by Pencil Test, the specification defined for determining the hardness of coating film. It specifically clarifies the load in the test method and evaluation items in the evaluation method.
This Specification defines the measurement method of surface hardness of FPD components excluding glass. This test method is applied for, for example, polarizing film, color filter, plastic substrates, touch panel, and other components of FPD applications.
