Abstract
(EN) A conductive film has a transparent substrate and a conductive portion having a wiring pattern. At least from one perspective, the wiring pattern has a moiré evaluation index of less than or equal to a prescribed value. The moiré evaluation index is calculated from a moiré evaluation value, obtained by applying the effect of human visual response characteristics in accordance with the observation distance, to a moiré strength at each moiré frequency at or below a maximum moiré frequency, which is determined according to the display resolution of a display unit, at a moiré frequency and strength respectively calculated from the peak frequency and peak strength of prescribed data, and from the peak frequency and peak strength of another prescribed data.
(FR) L'invention porte sur un film conducteur qui possède un substrat transparent et une partie conductrice ayant un motif de câblage. Au moins d'un point de vue, le motif de câblage possède un indice d'évaluation de moiré inférieur ou égal à une valeur prescrite. L'indice d'évaluation de moiré est calculé à partir d'une valeur d'évaluation de moiré, obtenue par application de l'effet de caractéristiques de réponse visuelle humaine selon la distance d'observation, sur une intensité de moiré à chaque fréquence de moiré égale ou inférieure à une fréquence de moiré maximale, qui est déterminée selon la résolution d'affichage d'une unité d'affichage, à une fréquence et une intensité de moiré respectivement calculées à partir de la fréquence de pic et de l'intensité de pic de données prescrites, et à partir de la fréquence de pic et de l'intensité de pic d'autres données prescrites.
