Publication number: 20120044561Abstract: In an electrochromic module combined with organic and inorganic materials and a display device combined with the module, the display device has the electrochromic module installed on a surface of an image display module, and the electrochromic module comprises a first transparent substrate, a second transparent substrate, and a transparent conductive element and an electrochromic layer disposed between the substrates, and the electrochromic layer is made of mixing an organic material and an inorganic material into a solvent. With the transfer of electrons between the organic and inorganic materials, the valence of ions of the materials is changed. By gaining electrons for a reduction, and losing electrons for an oxidation, a color change is achieved, and the invention has the advantages of high speed, uniformity, and a low driving voltage.Type: ApplicationFiled: May 3, 2011Publication date: February 23, 2012Applicant: J TOUCH CORPORATIONInventors: YU-CHOU YEH, CHAO-YI WANG, WEN-CHIH LO, TSUNG-HER YEH

Publication number: 20120038966Abstract: In an electrochromic module and a display device integrated with the electrochromic module, the electrochromic module is installed on a surface of the display device and includes a first transparent substrate and a second transparent substrate. A transparent conductive element and an electrochromic layer are disposed between the two substrates, and the material of the electrochromic layer is prepared by dissolving an indicator into a solvent, and electrons are used to change the valence of ions inside the material, such that a coloration is resulted from reduction and oxidation caused by supplying and removing electrons to the ions respectively, and the electrochromic coloration rate is quicker and more uniform than present existing electrochromic materials. Unlike achromic mechanism that produces a decoloration by the oxidation and reduction of organic electrochromic materials, the electrochromic module and the display device have the advantages of a quick decoloration and a small driving voltage.Type: ApplicationFiled: November 23, 2010Publication date: February 16, 2012Applicant: J TOUCH CORPORATIONInventors: YU-CHOU YEH, CHAO-YI WANG

Patent number: 8064119Abstract: This invention provides a novel electrochemical display element, which can realize bright white display, high-contrast black and white display, and full-color display by a simple member construction, and a method for driving the display element. The display element is characterized in that it comprises opposed electrodes, and an electrolyte, an electrochromic compound, a metal salt compound, and a white scattering material between the opposed electrodes, and multicolor display of three or more colors is carried out by black display, white display, and display of color other than black by driving the opposed electrodes by taking advantage of 1) a color change as a result of oxidation and reduction reactions of the electrochromic compound, and 2) a color change as a result of reduction precipitation and oxidation dissolution of a metallic element contained in the metal salt compound in at least one of the opposed electrodes.Type: GrantFiled: November 14, 2007Date of Patent: November 22, 2011Assignee: Konica Minolta Holdings, Inc.Inventors: Noriyuki Kokeguchi, Takeshi Hakii, Osamu Ishige
