SEMI D34 - Test Method for FPD Polarizing Films
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 2003; previously published June 2010.
This Standard establishes implementation guidelines for the measurement of visual appearance, thickness, and optical characteristics of FPD Polarizing Films. These methods can be applied in manufacturing, quality control, and research and development.
This Document specifies measurement methods.
Specifies measurement methods for visual appearance (dot defects, line defects, visual exclusion area), thickness, optical characteristics (single transmittance, parallel transmittance, cross transmittance, UV cut performance, polarization efficiency, hue a, b and hue a*, b* and haze) of polarizing films.
