CONDUCTIVE FILM, DISPLAY DEVICE EQUIPPED WITH SAME, AND METHOD FOR DETERMINING PATTERN OF CONDUCTIVE FILM

摘要

The conductive film has a wiring pattern which, with respect to the frequencies and intensities of moire obtained by applying a human visual response characteristic to the frequency information and intensity information of moire calculated from peak frequencies and peak intensities of the two-dimensional Fourier spectrums of the transmittance image data of the wiring pattern and the transmittance image data of a pixel array pattern, causes the sum of intensities of moire each corresponding to frequencies of moire falling within a frequency range predetermined depending on the visual response characteristic to be less than or equal to a predetermined value. The conductive film allows suppression of moire and significant improvement in visibility.

1. A conductive film adapted to be installed on a display unit of a display device, comprising:
a transparent substrate; and a conductive portion including a plurality of thin metal wires that is formed on at least one surface of the transparent substrate, wherein the conductive portion has a wiring pattern which is formed by the plurality of thin metal wires in a meshed manner and provided with a plurality of openings arrayed, wherein the wiring pattern is superimposed on a pixel array pattern of the display unit, and wherein the wiring pattern is a wiring pattern which, with respect to frequencies of moire and intensities of moire obtained by applying a visual response characteristic of human beings to frequency information of moire and intensity information of moire calculated from peak frequencies and peak intensities of plural spectrum peaks in a two-dimensional Fourier spectrum of transmittance image data of the wiring pattern and peak frequencies and peak intensities of plural spectrum peaks in a two-dimensional Fourier spectrum of transmittance image data of the pixel array pattern, causes a sum of intensities of moire each corresponding to frequencies of moire falling within a predetermined frequency range determined depending on the visual response characteristic to be less than or equal to a predetermined value.
