This part of IEC 62977, which is a Technical Report, reviews the impact of test pattern colour content and image loading on the measured display’s photometric and colorimetric performance. Experimental data for several display technologies is presented to demonstrate the need for using a broader range of colours in the test patterns, and measuring the display at an image loading level appropriate for the intended application.
