Abstract

The perception of a display’s content can be negatively influenced due to surface properties and variable ambient light conditions. Conventional measurement methods, such as DIN EN ISO 2813, provide limited information on the relationship between gloss values and gloss perception. Generally, there are no further statements about scattering or disturbing reflections and their correlation to perception. This work presents the development of a display measuring device which can measure several optical parameters simultaneously as well as in a spatially resolved manner. The measuring principle was oriented on the DIN EN ISO 2813 standard with measuring reflection geometries of 20° and 60° relative to the normal. The determined objective properties were correlated with the subjective perception of the end user using a laboratory study. In this study, subjects assessed the reflections from the displays in terms of gloss and scatter on a scale of 1 (minimal) to 5(maximal). The influence of different settings of viewing positions, ambient brightness and display brightness was investigated. For the comparison between objective and subjective data, the subjective scale was related to the objective measured value for gloss and dispersion. A correlation between objectively measured data and the subjective perception of optical properties of displays was observed. This correlation occurs mainly in extremely glossy and matt displays.
