  • Patent number: 9645694
    Abstract: The conductive film which can inhibit the occurrence of moire and can greatly improve recognition property, a display device equipped with the conductive film, and a method for determining a pattern of a conductive film are provide. In the conductive film, a spectral intensity of moire of a lowest frequency is equal to or less than ?3.6 expressed in terms of common logarithm, and the spectral intensity is represented by convolution of spatial frequency characteristics of the mesh pattern that are obtained at least when the mesh pattern is observed from a front side and spatial frequency characteristics of the pixel array pattern of the display unit that are obtained at least when the pixel array pattern is observed from a front side. The mesh pattern may include a plurality of disconnection portions.

  • Patent number: 9612705
    Abstract: An electroconductive film includes a transparent conductive layer having a plurality of electrodes which extend in one direction. The electrodes have different electrode widths depending on the site, and are configured of a plurality of polygonal cells formed of fine metal wires. The sizes of the respective cells are not uniform. The average size of the cells is greater than or equal 1/30, and less than 1/3, of the narrowest width of the electrodes. The average size of the cells is uniform in the electrodes overall.
