Method of manufacturing conductive sheet, conductive sheet, and recording medium

Abstract

The method of manufacturing a conductive sheet of the present invention is provided with: a creation step for creating image data that indicates a meshed pattern; and an outputting step for outputting and forming wire materials on a base body on the basis of the created image data, and manufacturing a conductive sheet having the meshed pattern. The image data has, in convolution integration of a power spectrum of the image data and standard vision responsiveness of human beings, a characteristic of having each of the integration values at a spatial frequency band that is not less than 1 / 4 and not more than 1 / 2 of a Nyquist frequency corresponding to the image data to be greater than integration values at a null-space frequency.

Description

technical field [0001] The present invention relates to a method for producing a conductive sheet in which mesh wires are formed on a substrate, the conductive sheet, and a recording medium storing a program for manufacturing the conductive sheet. Background technique [0002] Recently, a conductive sheet in which mesh-like wires are formed on a substrate has been developed. The conductive sheet can be used as an electrode or a heat generating sheet. For example, the conductive sheet is applied not only to electrodes for touch panels, inorganic electroluminescence (EL) elements, organic EL elements, or electrodes of solar cells, but also to defrosters (defrosters) of vehicles. device) or electromagnetic wave shielding material. [0003] For users of the above-mentioned various articles, in terms of the nature of their use, the shape of the mesh pattern may correspond to granular noise that hinders the visibility of the object to be observed. In response to this, various t...

Problems solved by technology

[0010] In this way, in order to further improve the visibility of any one of the windows for passenger vehicles disclosed in Japanese Patent Laid-Open No. 2009-137455 or the transparent conductive substrate disclosed in Japanese Patent Laid-Open No. 2009-016700 , there will be adverse situations in which light transmittance or productivity decreases

[0011] In addition, since the pattern PT3 disclosed in Japanese Patent Laid-Open No. 2009-302439 does not have a mesh shape, a difference occurs in the wiring shape of the cut surface.

Thus, when the pattern PT3 is used as an electrode, for example, there is a disadvantage that stable conduction performance cannot be obtained.
