BenævnelseDenominations
Bag projektbar skærm eller lærred Frembringelsens anvendelses områdeBehind projectable screen or canvas The scope of application
Denne opfindelse kan benyttes som bag belyst skærm eller lærred, eventuelt ved benyttelse afbag belysning af film, lysbilleder, projektion af data, tekst eller lyseffekter, samt alle medie gengivelses apparat baseret på lys.This invention can be used as behind illuminated screen or canvas, optionally by using off-light illumination of film, slides, projection of data, text or lighting effects, as well as any media rendering apparatus based on light.
Folien som projekteres på er Ink Jet lignede Film, af polyester, PVC, polyethylen eller polyprophylene, alle mat eller halv mat hvidmeleret overfladeThe film projected on is Ink Jet resembled Film, made of polyester, PVC, polyethylene or polyprophylene, all matte or semi matte whitewashed surface
Kendt teknikPrior art
Bag projekteret skærm er i dag kendt princip. Denne består af en dug/skærm monteret af et transparent materiale som gengiver det bagfra kommende medie projekteret på skærmen. De kendte principper er i dag 1 En grå polyester/akrvl bagprojekterende gummilignedc dug.Behind the projected screen is today known principle. This consists of a tablecloth / screen mounted on a transparent material that reproduces the background media projected on the screen. The known principles are today 1 A gray polyester / acrylic back projecting rubber lined fabric.
2 Cineflex en fleksibel gummilignede dug til udspænding på ramme.2 Cineflex a flexible rubber-like tablecloth for frame tension.
3 Diffusions bagprojekteringsskærm - specialstobt matgrå akrylplade. Antirekflektiv betragtningsside.3 Diffusion rear projection screen - specially molded matte gray acrylic plate. Antireflective viewing site.
Det tekniske problemThe technical problem
Ved kendt bagprojektionsskærm vil man fra en betragtnings position af signalet med 90 graders position kunne oplever billedkvalitet maksimalt hvad angår lys og gengivelse.With a known rear projection screen, from a viewing position of the signal with a 90 degree position, image quality can be experienced maximum in terms of light and reproduction.
Ved en afvigelse fra en 90 graders betragtning position til skærmen vil en + - 90 graders ændring til denne position forvrænge billedkvalitet proportionalt med lys og kvalitet. Ved en 170 graders placering vil et billede på kendt skærm være umulig.By deviating from a 90 degree viewing position to the screen, a + - 90 degree change to this position will distort image quality in proportion to light and quality. At a 170 degree location, an image on familiar screen will be impossible.
Den nye teknikThe new technique
Ved denne teknik er et minimalt signal / lys tabIn this technique, a minimal signal / light loss
Enten placeret alene, ved eller imellem glas eller plast pladerEither placed alone, by or in between glass or plastic sheets
Den tekniske virkningThe technical impact
Plastfoliens gengivelse forringes ikke ved opfattelse af billedmediet ved ændring af beskuerens placering DK 2002 00083 U3The plastic film reproduction is not impaired by perception of the image medium by changing the viewer's location DK 2002 00083 U3
Brugsmodelkrav.Use Model Requirements.
Bag projekter bar skærm eller lærred, enten placeret alene, eller ved, eller imellem glas/ plast.Behind projects carried a screen or canvas, either placed alone, or by, or in between glass / plastic.
Skærm eller lærred består af en folie lignede film. Materialet er klar eller hvid meleret plastfolie, med en mat eller halv mat meleret overflade.Screen or canvas consists of a film similar to film. The material is clear or white coated plastic foil, with a matte or semi matte surface.
