Patent number: 8692765Abstract: A 2D/3D image switching display device includes an image display unit and an image switching unit coupled to the image display unit. The image switching unit includes first and second transparent substrates and first and second transparent conducting elements installed on the first and second transparent substrates respectively. An electrochromic layer and an electrolytic layer are formed on the first and second transparent substrates sequentially. The electrochromic layer produce a color change according to the switching status of the image display unit After a stereo image divided into left and right eye images is received by naked eyes, no moire pattern will be produced, so that no additional light shielding device using a parallax barrier is required for displaying stereo images, and the 2D/3D image switching display device can change a light-shielding angle for adjusting a stereo image display according to the viewing angle.Type: GrantFiled: September 21, 2010Date of Patent: April 8, 2014Assignee: J Touch CorporationInventors: Yu-Chou Yeh, Chao-Yi Wang, Chi-Hsien Sung, Min-Hui Chiang

Patent number: 8368991Abstract: A 3D image display device includes a display module, an electrochromic module, a control unit and a sensing unit. The electrochromic module has a first electrochromic element and a second electrochromic element disposed in the different direction, and the electrochromic element is a solution type electrochromic material, and the valence of ions in the material is changed to produce a quick and uniform coloration. The display device transmits a detect signal of the sensing unit to the control unit, and the control unit controls the coloration/decoloration of the first and second electrochromic elements to switch the horizontal or vertical parallax barrier, such that viewers can view a 3D image from different viewing angles and directions.Type: GrantFiled: May 18, 2011Date of Patent: February 5, 2013Assignee: J Touch CorporationInventors: Yu-Chou Yeh, Chao-Yi Wang, Wen-Chih Lo, Chi-Hsien Sung, Tsung-Her Yeh

Publication number: 20120224246Abstract: A grating structure of a 2D/3D switching display device comprises: a first transparent substrate, a first transparent conductive film; a second transparent substrate, and a second transparent conductive film disposed with an interval apart with each other on a side of the first transparent conductive film, such that a potential difference is produced between the first transparent conductive film and the second transparent conductive film; a solution type electrochromic material, disposed between the two transparent conductive films; an isolating element, made of an inorganic material, and disposed on a side of the second transparent conductive film; and a conductive wire layer, disposed on a lateral periphery of the first transparent conductive film and/or the second transparent conductive film. After the conductive wire layer is electrically conducted, the conductive wire layer with a low resistance accelerates the conduction of current, so as to improve the efficiency and uniformity of coloration.Type: ApplicationFiled: April 13, 2011Publication date: September 6, 2012Applicant: J TOUCH CORPORATIONInventors: YU-CHOU YEH, CHAO-YI WANG, WEN-CHIH LO, CHI-HSIEN SUNG, TSUNG-HER YEH

Publication number: 20120081773Abstract: In an electrochromic module and a stereo image display device having the electrochromic module, the electrochromic module includes a first substrate, a second substrate, at least one electrochromic layer and at least one ion layer. The first substrate upper surface includes at least one first electrically conductive element disposed between the first substrate and the second substrate. The ion layer is formed on a surface of the electrochromic layer and prepared by mixing and dissolving at least one organic material and at least one inorganic material in a solvent. The ion layer not only serves as an ion provider, but also acts as an electrochromic material of an accessory color change layer for improving the difference of the optical transmittance. By the shifting and transmission of electrons between the organic and inorganic materials, the electrochromic module has the advantages of fast and uniform color change and smaller driving voltage.Type: ApplicationFiled: December 15, 2010Publication date: April 5, 2012Applicant: J TOUCH CORPORATIONInventors: YU-CHOU YEH, CHAO-YI WANG, WEN-CHIH LO, CHI-HSIEN SUNG, TSUNG-HER YEH
