Abstract

Screens are already used for projecting images in cinema, video projection, television, computers and slides. Not all of these screens bring the image to life sufficiently due to a saturation with light which overwhelms the image and which is too intense for the eye. The aim of the inventive method is to respect the physiological parameters of sight and present the image in three dimensions and to give it a chromatic dynamic and a much greater range of shades, the latter being obtained by light diffraction of multilayer screens. The multiple layers diffract the rays of light coming from the projector, which are partially reflected on at least one first transparent or translucid layer that is embossed in places, with slightly different angles of incidence, and on at least one second, very reflective structure. The image seen by the viewer is the sum of all of these effects of diffraction. The overall perception is that of a three-dimensional image and an impression of intensified light. According to the inventive method, a fabric-type device is produced with a very luminescent thread at the back and a transparent thread woven in the surface. This fabric is embossed so as to produce a relief. The fabric is also useful for acoustics for use in a cinema screen. Another variant can be produced for television and computer screens according to this method. The method and device for high definition image vision and light intensification using direct light incidences can be applied to the fields of cinema, audio visual technology and image projection.

Description

High definition screen

Background of the present invention

In film, video-projection, lantern projection, TV and computer realm, use screen to come as far as possible directly projection to go out image colored or black and white, and directly the intensity at peak is tended to " flooding " image.

Screen has the pearlitic texture that uses independent particle or band particle decorative pattern net, has sharp-pointed or level and smooth edge, and TV screen is then used the film of fluorescent material.The screen that use in the film field is a kind of special situation, because they should have micropore, allows can see through screen from the tail sound of screen, passes to the audience there that is sitting in the motion picture screen front.

Such screen can not give image with enough fidelitys, promptly can not make shades of colour have same intensity of colour.Stereopsis also lacks good compensation, because light is saturated too strong concerning eyes, causes a dull impression without any the yardstick in space.

Summary of the present invention

This method is intended to follow the physiologic parameters to the visually-perceptible impression, makes it possible to provide three-dimensional outward appearance and color fidelity, and compensation is owing to use the excessive look that tone range caused that is obtained by optical diffraction poor by force.

This method comprises sets up a sandwich construction with at least two different structure unit, unit be arranged on another above: the layer of luminous light in other words is generally overleaf, form main image at this, on the surface of spectators' one side be at least one deck translucent or transparent the layer.

This sandwich construction is being pressed decorative pattern at least one of its structural unit, perhaps become the concaveconvex shape of irregular surface, such as the three-dimensional pattern of diamond shaped or repetition.This three-dimensional pattern that obtains can have square, rectangle, cellular or coniform, and decorative pattern side by side can be staggered fully or connect, and perhaps locatees with another fully for one.

Therefore this method relates to the screen field of the film, lantern projection, image projecting or the TV that use the high definition image display packing, the method has strengthened the light component of the raw video of diffraction, make it produce diffraction by different reflection horizon, this screen one deck at least in its multilayer has embossing decorative pattern or concavo-convex decorative pattern (lenticulations) with taking up an official post choosing.The method relates to the light amplification that the image reflection that produced by the repetition decorative pattern sandwich construction screen of image projecting on it is carried out.The screen bottom that produces a part of main image be bright, have high reflectance, this screen also has a kind of in other words member of one deck, also forms another part spectrum of image here, this part is translucent or transparent, and is colourless.Become diffraction light from projector's emitted light beams, on two faces of its first surface layer member by partial reflection, also allow light beam pass the backing layer that arrives screen, this backing layer has height fluorescence, this layer is delivered to light on the superficial layer more for the second time, owing to its uneven looks make incident angle slightly different.The image that audience or spectators accept is the summation of these diffracting effects of selecting meticulously, and its general impression is the image of high definition.Because the diffraction on Mnltilayered structures, little significantly light component feels just much better than from physiological viewpoint, can demonstrate three-dimensional, and has eliminated because " flooding " phenomenon that too strong direct reflected light causes.The information content of the abundanter and less aggressiveness of visual physiology preference (aggressive), feeling of visual intensity is the summation of same levels light component information.This method is followed the physiology needs of vision.Can clearly feel the spectral resolution that causes by natural optical filtering form and structure, make the spectators can be tired, and total light intensity be much higher.

Being described in detail of preferred embodiment

The equipment of implementing this method comprises at least one first member, this member is the minute surface of a silver color, this minute surface is the 2m height, and 5m is wide, is made by glass or Perspex , has the mold pressing pattern above, embossing or ridge design, decorative pattern are millimetre-sized diamond shaped and arrange each diamond shaped object depth 5mm, long 8mm, wide 3mm.This minute surface with irregular surface is provided with at least one second translucent or transparent component, and this member comprises the thin glass plate that 1mm is thick, has ridge design in the decorative cover of part shoot mark formula (shot blasted type) or the mold pressing.These two members are tightly fit together by synthetic material, form the multilayer screen with light amplification effect for visual projection usefulness.This screen is placed by wall, can allow the people feel the image of high definition, and this embodiment is not exclusive.

Another also the example of the determinate embodiment of right and wrong be a light amplification type fabric screen, this woven fabric is to have the metal-plastic silk braiding of 0.37mm plane section, the metallic aluminium of this high reflectance-plastics silk is formed the back of fabric.When using with aluminium wire, wide 0.25mm, the polyester capillaries of thick 12 μ m are made at least a transparent fabric in front, form the fabric face in the face of spectators.This fabric that all can make the professional of field of textiles forms decorative pattern, the fabric that obtains having repetition irregular surface effect by the heat embossing operation again.The fabric that so constitutes according to method of the present invention has the performance of optical diffraction, and can see through sound when using at the cinema.This kind fabric screen approximately is 5dB to the absorption of the sound that in fact evenly runs through whole audiorange, so obtains the multilayer screen of high optical property, and its transmission to sound also is quite valuable.

Another embodiment of this method is the screen that uses in TV and computer realm, this screen is on the inside surface or outside surface of pipe, perhaps on front surface that forms image or two sides, rear surface, use micro-embossed or mold pressing ridge design, engraving or shoot mark formula repeat decorative pattern, face at it then and cover a translucent or transparent member on spectators' the front surface, it such as thickness several microns ultra-thin embossing overlay, cover the upward projection of thickness 2mm and the glass plate of optical effect on the whole again, constitute the bonding multilayer screen of high definition thus, this embodiment neither be exclusive.

This method and equipment are used for high definition image and show, have the multilayer screen of irregular surface decorative pattern and have the light amplification effect that obtains by direct incident optical diffraction simultaneously by use, this kind method and apparatus can be used for film and audiovisual field, and all spectra of making video.
