No, this seems to be one of the areas where you misunderstand. Consider, for example, projection glasses (which present an image directly to the eyes) -- there is no 'display surface' on which to measure. In other cases, there is a display surface, but it's inappropriate to apply the measurements directly (e.g. on a billboard display a single pixel may exceed a physical inch on the display surface). As others have indicated, please read the (extensive) threads on this subject, where this was discussed. David Singer Multimedia and Software Standards, Apple Inc.
