Definitions

  • the goal of the herewith patent of invention is to supply the public, through specific assembly process, a gadget to receive image projection, that is: a projection screen that allows the configuration of a view at an 360 angles, overcoming all the inconveniences and limitations of screens known nowadays and available in the market, being inclusively certain new projection screens being used at any environment, commercials or residentials, availabling the projected images on both opposite sides of the referred screen, using as projector equipment any conventional equipment of image projection, as projector, datashow, big screen or the retro projector.
  • PICTURE 1 represents a perspective screen view projection, standing out the parts that consist the assembly process, in a specific sequence
  • PICTURE 2 represents in a blown up way, the three parts of the projection screen;
  • PICTURE 3 figures another view as how the projected image will be available simultaneously on both sides of the projection screen;
  • PICTURE 4 figures a view, representing how the users will have access to the 360 angles field of view.
  • a DESIGN FILM AND RESULTANT PRODUCT is consisted of a board of glass, acrylic or Lexan ( 1 ), self adhesive, duo part or optic adhesive ( 2 ) and a vinyl film or pellicle ( 3 ), properly adhered to themselves in an specific order, forming the projection screen ( 4 ), that allows the image on both sides, frontal anterior ( 4-A ) e posterior ( 4-B ), obeying the following manufacturing process that consists of adhere first the self adhesive ( 2 ) on one of the vinyl film surfaces ( 3 ) through specific equipment and followed by gluing the specific vinyl film ( 3 ) already properly plastered to the self adhesive ( 2 ) on the board of glass, acrylic or Lexan ( 1 ), using specific machine for such gluing operation or through manual execution, using plastic spatula and water being that, for the last process, the period for drying is from 10 to 30 days, depending on air humidity.
  • Picture 3 approach shows how the projected image on screen ( 4 ) is perfectly available simultaneously on both sides: frontal ( 4-A ) and posterior ( 4-B ); this picture, we have the evidence that the image projected on the surface ( 4-B ) is inverted, however, with the fidelity on the quality of the projected image and making use of available resources in the retro projector equipments, which allow the automatic inversion of eventual subtitles, the user will not have any loss, for the inversion is practically unnoticed.
  • the resultant product that is, the screen ( 4 ) could be used at any environment, professional, commercial or residential, increasing considerably the aesthetic point of the referred environment, the screen being able ( 4 ) to be adapted to the own environment construction, sharing it, or being fixed through the specific gadgets on the ceiling, in the mezzanine, about eventual boards and even on the wall, in this case, the projected image will be available only at one side, being put a dark background on the other surface, that shows the referred equipment the similar qualities of a plasm screen, due to its thin thickness.
  • the dimensions of the screen ( 4 ) resultant product of this patent of invention can vary according to the size of the films or pellicles available in the market nowadays, following the eventual variations that market shows.
  • the users will be able to use this projection screen, object of this patent of invention, replacing the retro projection TVS screens, whose quality of image is known very low, using from the same TV equipment.

Abstract

La présente invention concerne un procédé d’obtention et de visualisation simultanée d’images sur les deux côtés d’un écran de projection et le dispositif résultant, qui se caractérise par le fait d’un appariement, au moyen d’une liaison spécifique, d’un type de film ou pellicule vinylique (3) à un adhésif optique (2), appliqué sur un support en verre, acrylique ou Lexan (1), avec réflexion sur un écran de projection (4) permettant la visualisation d’images provenant de différentes sources, notamment : TV, TVHD, DVD, vidéos, diapositives, données informatiques ou toute autre source électronique de projection d’images. L’image est projetée sur l’une des surfaces de l’écran de projection (4), mais sa visualisation est possible sur les deux côtés de l’écran. L’utilisateur dispose ainsi d’un affichage classique de la surface frontale, mais également d’un autre affichage inhabituel sur la face arrière de l’écran.
