SEMI D76 - Test Method for Viewing Angle Characteristic Using Reference Color on Visual Displays
This Standard was technically approved by the Flat Panel Display Global Technical Committee. This edition was approved for publication by the global Audits and Reviews Subcommittee on December 13, 2017. Available at www.semiviews.org and www.semi.org in March 2018.
The viewing angle characteristic of display panel is one of the most important components of image quality.
Even though there are several viewing angle measuring methods for luminance and color, they do not sufficiently deal with real world mixed colors for viewing angle.
A new viewing angle measuring method is suggested which evaluates the variation of mixed color using reference color patches based on CIELAB color difference metric.
This Standard is applicable to large screen flat panel display such as non-portable TV and monitor in a dark room.
The scope of the term ‘viewing angle characteristic’ is related to both luminance and color variation in this Standard.
This Standard defines only horizontal and vertical viewing angles for measurement.
