DANSK DSF/IEC TR 62977-5-2 ED1 PDF

This part of IEC 62977 describes visual assessment method of viewing direction characteristics of display devices. This technical report reviews the visual assessment on viewing direction by using special test patterns to estimate colour changes, image structure, and image luminance. Experimental results are shown to reveal the effectiveness of this kind of visual assessment. This method is a valuable tool for identifying image quality issues, but physical measurements should be used to confirm display performance specifications. Note: The visual assessment results will depend on the test pattern parameters and display setup conditions. As the viewing direction is changed, characteristics such as contrast ratio, resolution, and device colour-shift simultaneously change in the perceived image.
