発明の名称 (英語) ELECTROCHROMIC RENDERING/DISPLAYING DEVICE
発明の概要(英語) The present invention is provided with: a substrate 10; a lower conductive film 12 disposed on the substrate; an electrochromic material 14 and an electrolyte 16 disposed on the lower conductive film; an upper transparent conductive film 24, disposed on the electrochromic material and the electrolyte, with an insulating spacer 22 interposed therebetween; a transparent film 26 disposed on the upper transparent conductive film; and a means (28) for applying a voltage between the lower transparent conductive film and the upper transparent conductive film, wherein when the transparent film is pressed from the upper surface thereof, the transparent film is bent, a gap formed by the spacer disappears, the upper transparent conductive film is brought into electrical contact with the electrochromic material or the electrolyte thereunder so as to locally pass an electrical current, an electric field is applied only to a portion, of the electrochromic material, directly under the contact point, and thereby, a local color of the electrochromic material is changed. Accordingly, the electrochromic rendering/displaying device which allows a local color change (coloring, decoloring, discoloring) by means of a simple structure is provided.
従来技術、競合技術の概要(英語) BACKGROUND ART
Voltage, by applying high current, electrochemical oxidation, a reversible color change is obtained by the reduction of the electrochromic material is known.
Such as the electrochromic material, an inorganic material or organic material systems are present. As inorganic materials, oxide (tungsten oxide, vanadium oxide, molybdenum oxide, iridium oxide, rhodium oxide, nickel oxide, an oxide such as chromium oxide), metal complex (Prussian blue, and complexes of ruthenium purple), such as a nitride-based (indium nitride or the like), the various material systems. As an organic material, the viologen system, the leuco dye-based compound, a terephthalic acid compound, , polymer-based (conductive polymer compound, such as metallo supramolecular polymer) or the like, the various material systems.
Is an electrochromic device, the electrochromic material layer is sandwiched between the electrode and electrolyte layers, by applying a voltage, principally oxide, such as the reduction of the electrochemical reaction causes a color change is used. In such an electrochromic device, the electrochromic layer and the liquid type and a solid-state, the liquid-type electrolyte layer, the gel mold, is a solid-state.
Such as an application of the electrochromic device, the electronic paper, display, and a display device such as a finder, light control glass, an electron curtain, sunglasses, the light-shielding device such as the anti-glare mirror has been known.
The electronic paper, as a display, a viologen compound-based full-color electronic paper (non-patent document 1) and, using the metallo supramolecular polymer (Patent Document 1) or a color electronic paper, using a Prussian blue (non-patent document 2) and the like. The finder is, the oxide-based electrochromic material are sometimes used. Light control glass, an electron curtain, sunglasses, anti-glare mirror has been put into practical use.
In addition, with respect to the electrochromic film, a liquid or solid electrolyte portion mounted to the front end (the pen) is prepared, the distal end of the implanting ions from the electrolyte out of the color, the drawing, erasing (Patent Document 2) is electrochromic printing apparatus. In addition, with respect to the method of application, as an application associated with the electrochromic method other than by, an electronic white board or an electronic notepad and the like (note).
