Patent number: 9128369Abstract: A method by which optical filter structures may be applied onto a substrate that is transparent to light at least in the visible wavelength range suitable for a barrier filter. In such a method, an adhesive is applied onto the substrate; then, a photographic film comprising a base film and a photographic emulsion layer applied on it is brought into contact with the adhesive. The optical filter structures are impressed in the photographic emulsion layer by exposure, development and fixation. The side of the film brought into contact with the adhesive is the one that bears the photographic emulsion layer. The adhesive is then spread between film and substrate by means of a roller rolling across the film at a specified contact pressure and a specified feed rate of the roller and thus pressing the film against the substrate. A permanent joint between substrate and photographic emulsion layer is then established by the curing of the adhesive.Type: GrantFiled: April 16, 2010Date of Patent: September 8, 2015Assignees: Secco GmbH, 3D International Europe GmbHInventors: Ullrich Daehnert, Juergen Schwarz, Stephan Otte

Patent number: 8421934Abstract: The invention relates to a method for orienting an optical element (e. g. a parallax barrier screen or lenticular screen) on a screen comprising pixels x(i, j) in a raster composed of lines (i) and columns (j) in order to produce a screen for three-dimensional representation. In said method, especially a test pattern is presented which consists of various views A(k), wherein k=1, . . . , n, and n>1. The test pattern comprises at least two first straight lines that are located in different horizontal positions in the n>1 views A(k) as well as at least two second straight lines which each extend parallel to one of the first straight lines and are located in at least the same horizontal positions in the n>1 views A(k). The method according to the invention can be carried out quickly and with high accuracy and is therefore suitable for industrial use to produce screens for three-dimensional representation.Type: GrantFiled: June 2, 2008Date of Patent: April 16, 2013Assignee: VisuMotion GmbHInventors: Stephan Otte, Jens Meichsner

Publication number: 20120104637Abstract: The invention relates to a method for fabricating objects with a structured optically effective surface for fabricating lenticular screens. The method may comprise: applying a liquid plastic layer, consisting of a plastic that will cure by the input of energy, onto a substrate, smoothing the surface of the liquid plastic layer, inputting energy into the plastic, wherein the amount of energy to be applied per unit of time is specified for different positions as a function of the structure height to be produced in these positions, so that, as a result of the energy input, different quantities of still uncured and already cured solidified plastic exist in different positions of the surface, and removing the uncured plastic whereby the remaining, cured plastic defines an optically effective structure.Type: ApplicationFiled: April 16, 2010Publication date: May 3, 2012Applicants: 3D INTERNATIONAL EUROPE GMBH, SECCO GMBHInventors: Ullrich Daehnert, Juergen Schwarz, Stephan Otte
