Title:
ELECTRICALLY-CONDUCTIVE FILM, DISPLAY DEVICE PROVIDED WITH SAME, AND METHOD OF EVALUATING ELECTRICALLY-CONDUCTIVE FILM
Document Type and Number:
WIPO Patent Application WO/2016/002676
Kind Code:
A1
Abstract:
In an electrically-conductive film, a method of evaluating a pattern in the electrically-conductive film, and a display device, thin metal wires in at least one wiring line portion of two wiring line portions include thin metal wires forming a wiring line pattern in which opening portions are parallelograms, the angles of said parallelograms being maintained in relation to rhombic shapes in a regular rhombic wiring line pattern, and the pitches of said parallelograms being made to be irregular in relation to the pitches of the rhombic shapes in said regular rhombic wiring line pattern. The wiring line patterns of the two wiring line portions are configured in such a way that a moiré evaluation index is at most equal to an evaluation threshold. The moiré evaluation index is calculated from moiré evaluation values for each color, obtained by causing a human visual response characteristic to act, in accordance with an observation distance, on a moiré intensity for each color, said moiré intensity being at least equal to an intensity threshold, at a moiré frequency for each color, said moiré frequency being at most equal to a frequency threshold, where said moiré intensity and said moiré frequency are calculated for each color from two peak frequencies and two peak intensities in two-dimensional FFT spectra from image data of the wiring line patterns of the two wiring line portions, and brightness image data from pixel arrangement patterns for each color when the colors are lit individually.
