CONDUCTIVE FILM, DISPLAY DEVICE EQUIPPED WITH SAME, AND METHOD FOR EVALUATING VISIBILITY OF WIRING

摘要

Human visual response characteristics taking into account offset values obtained from a photographic wiring image are applied to the first peak frequencies and the first peak intensities in a plurality of spectrum peaks in a two-dimensional Fourier-transformed spectrum from the photographic image data of the wiring in a conductive film wiring pattern superposed on a display unit to thus obtain second peak intensities in second peak frequencies. A quantitative value indicating the wiring visibility is calculated by summing the second peak intensities among all the second peak frequencies. This quantitative value is no more than a prescribed value.
