Definitions
- the invention relates to a method by which optical filter structures are applied to a carrier substrate which is transparent to light at least in the visible wavelength range.
- filters that have a complex structure perpendicular to the optical axis play a major role.
- An example of this are so-called barrier filters, which are used to allow a viewer of a screen a spatial vision without tools, provided that the image content to be displayed on the screen have been prepared accordingly.
- Such filter structures may be, for example, the arrangement of in the visible wavelength range, i. in a wavelength range of about 400 nm to 800 nm, transparent and opaque surfaces - perpendicular to the optical axis - in a given, complex pattern exist. Even surfaces that are permeable only for specific wavelengths or wavelength ranges are conceivable, as are lattice structures, but less in connection with the realization of spatial representations.
- the filter structures are usually applied to a light-transmitting carrier substrate.
- the carrier substrate is, for example, glass or a corresponding plastic in question.
- a cold laminating film is first laminated onto the carrier substrate.
- the cold laminating film is provided on its underside, with which it is connected to the glass substrate, with an adhesive layer. Also on top of the cold laminating film is such an adhesive layer. This will become a photographic film in a further step laminated.
- the carrier film is also dispensed with and worked only with an adhesive layer.
- Such a photographic film typically comprises a film backing such as cellulose or polyester, and a thin photosensitive layer, the so-called photoemulsion, which is actually a suspension, i. is a mixture of a liquid and solids distributed therein, namely the slurry of finely divided crystals in gelatin.
- the crystals are usually silver halides, i. Silver chloride, silver bromide or silver iodide.
- the photoemulsion is then exposed by imaging a pattern corresponding to the complex optical filter structure onto the film. This can be done for example with the aid of a ready-made mask.
- the photographic filter is then - as usual and known in the art for a long time - developed and fixed to make the optical filter structure, which was imprinted into the photoemulsion, permanently light-resistant.
- the side of the film on which the photo emulsion is located is then laminated to the adhesive layer of the cold laminating film in the next step.
- a system is then obtained from the layers of glass - adhesive agent - cold laminating film - adhesive agent - photo emulsion - film carrier film.
- the filter In the two-time lamination there is a fundamental risk that dust particles, lint or other disorders, such as air bubbles, are incorporated into the photo emulsion, which can lead to significant impairment of the optical effect of the filter structure. In the worst case, the filter can not be used.
- the pressure applied during lamination of between 50 and 70 kPa which is usually applied via a roll or roller, results in slight distortion or stretching of the film, particularly in the direction of rolling.
- filter structures for spatial display screens which have a periodicity, this leads to a disturbance of the accuracy in the periodicity, whereby such a filter may even become unusable. Namely, the optical filter structures must be exactly matched to the pixel pitch of the screen - usually a liquid crystal display (LCD).
- LCD liquid crystal display
- the production method described above also poses problems if several of these optical filter structures are simultaneously applied to the carrier substrate. Smaller structures can be used for example for the screens of mobile phones, navigation devices or portable game consoles. If several filter structures, for example, applied to a glass substrate, the common glass substrate must then be separated between the filter structures. For this, the glass itself must be severed, including but also all other layers of the film carrier film over the cold laminating film to the lower adhesive layer must be severed. This can be done by means of appropriate carbide glass cutter. However, there are always unpredictable, irregular break lines and breakouts that lead to the loss of the entire, already manufactured optical filter. The overall layer system sometimes prevents just a clean separation and also leads to sharp-edged outbreaks that make re-use impossible, and also represent a great risk of injury. Again and again it comes to cuts despite the wearing of gloves.
- optical filter structures are applied to a carrier substrate which is transparent at least in the visible wavelength range by carrying out the following work steps: First, an adhesive is applied to the carrier substrate. Subsequently, a photographic film is brought into contact with the adhesive.
- the photographic film comprises a film carrier film and a photo emulsion applied thereto, in the photoemulsion the optical filter structures are already imprinted by exposure, development and subsequent fixation. The film is then brought into contact with the side of the film on which the photoemulsion is located, with the adhesive.
- the adhesive can be applied in a larger amount only at one point of the carrier substrate, wherein the amount is then dimensioned so that it makes it possible to bring the photographic film continuously in contact with the carrier substrate. Another possibility is to already distribute the adhesive over a surface which corresponds approximately to the surface of the film to be bonded to the carrier substrate.
- the adhesive is distributed between the film and the carrier substrate.
- the film is pressed by rolling a roller on the film with a predetermined contact pressure and a predetermined feed rate of the roller against the carrier substrate.
- the adhesive for example a viscous liquid with the viscosity of low-viscosity honey, is slowly distributed.
- both the surface of the carrier substrate, for which glass can be used, for example, and the photoemulsion on the film are wetted with the propagating adhesive.
- the contact pressure exerted by the roller on the film when rolling on the glass plate may not be too strong, otherwise it can come to stretching and stretching of the elastic film carrier film especially in larger film formats, especially in unwinding, resulting in corresponding changes in the regular intervals in result in the optical filter structures that can significantly disturb the desired three-dimensional effect.
- the contact pressure must not be too weak, since otherwise the adhesive would not spread sufficiently and the layer thickness of the adhesive layer between carrier substrate and photo emulsion could also be too thick.
- the layer thicknesses for the layer of the adhesive are between 10 ⁇ m and 30 ⁇ m.
- Contact pressure and feed rate are also given as a function of the temperature, which influences the viscosity of the adhesive, and of the properties of the selected adhesive.
- a contact pressure between 1 and 20 kPa - so much lower than in the prior art usual - and a feed rate of the roller between 0.5 and 20 mm / s is particularly preferred less than 10 mm / s, for example 3 mm / s, with contact pressure and feed rate also being coordinated.
- roller it is also possible to use a roller or another pressing means with which substantially the same effect can be achieved.
- a roller may also be used, which may be in the form of a ruler.
- a slider with triangular cross-sectional area - a surface to which the feed direction is parallel - can be used, wherein the slider can rest with a flat side, or with one edge of the triangle, preferably one with two legs of the triangle includes obtuse angle.
- the roller or roller can also have a very small diameter like a wire, provided that a sufficiently high contact pressure can be exerted.
- feed rate of about 3 mm / s has been found.
- the feed rate is still high enough to distribute the adhesive agent between the carrier substrate and the photo emulsion over the entire surface within a reasonable time, ie to apply the film completely to the carrier substrate.
- the speed is low enough to ensure that existing air pockets are virtually completely eliminated.
- a permanent bond between the carrier substrate and the photoemulsion is produced by curing the adhesive.
- “Permanent” refers to the usual life of such an adhesive bond under the conditions of normal use, not under extreme conditions of temperature, humidity, etc. If the adhesive, for example, water soluble and the compound is dissolved by the composite system is placed in water, so is Nevertheless, the connection can be regarded as permanent, since immersion in water is not considered to be a customary use.Curing can be carried out in various ways and, in particular, also depends on the adhesive used, for example, component adhesives can be used after the film has been unwound It is preferred, however, to use a liquid or viscous adhesive as the adhesive, which cures on exposure to ultraviolet light (UV light). Adhesion agents based on monomers are particularly preferably used here. which polymerize under UV exposure, i. linked to polymers.
- the film carrier sheet is thermally separated and removed from the photo emulsion.
- the temperature must be chosen so that the film support film on the one hand so much heated that it can be removed without residue from the gelatin layer, which forms the essential part of the photoemulsion.
- the gelatin layer should not be heated as much as possible: if the gelatin layer is heated too much, it can be destroyed when the film carrier film is removed.
- a heating element in the form of a heating plate can be used, which radiates heat with gleichverteilter temperature.
- This heating plate is used in the simultaneous heating of the entire film carrier film, the distance which the heat radiating heating plate has to the film carrier film is selected as a function of the temperature of the heating plate and on the thickness of the film carrier film or its thermal material properties.
- the film should heat up so much that it can be peeled off, the underlying photoemulsion, which consists mainly of a gelatin layer, not. This may at most in a very thin, near-surface layer warm enough that it is elastic in this area, but the photoemulsion layer is not destroyed when the film backing film is peeled off.
- Composite system and heating plate can be arranged in this case to each other stationary to each other, but also a relative movement between the two can be provided.
- a heating element with a surface heat-radiating in the direction of the film carrier film is guided over the film carrier film at a predefined distance at a predetermined speed for thermal separation of film carrier film and photoemulsion.
- the heating element can be, for example, a heating rail or a heating wire, it does not have to irradiate the entire film surface at the same time.
- the speed of movement of the heating element over the film carrier film depends on the temperature of the heating element, the distance of the heating element to the film carrier film, and the thermal properties of the film carrier film.
- the heating element can be stationary and the carrier substrate are guided past the heating element.
- the latter variant is even the preferred one, since all working steps are integrated into one system can be and the carrier substrate can be performed by appropriate workstations in the manner of a conveyor belt.
- the separation or detachment of the usually between 100 and 180 .mu.m thick film carrier film results in several advantages: First, the thickness of the system is reduced by the elimination of a layer, resulting in an improved transmission, so to an increased brightness the display of two- or three-dimensional images leads. On the other hand, however, eliminating an interface at which optical transitions regularly result in volume scattering substantially improves the contrast, both the image contrast decisive for the two-dimensional representation and the stereo or spatial image contrast decisive for the three-dimensional representation. which influences the channel separation.
- the photoemulsion actually a gelatine layer, after its development and fixation on its surface has pores or openings into which the adhesive can penetrate into the photoemulsion. If the adhesive penetrates too far into the pores, this can lead to too little adhesive remaining on the surface, which on the one hand can lead to poorer adhesion, but on the other hand also to the inclusion of air bubbles. For this reason, in a preferred embodiment of the method, a liquid which penetrates into pores or openings which are present in the photoemulsion or on its surface is applied to the photoemulsion.
- the liquid must have a composition which ensures that the pores are at least partially closed. This is the case, for example, when conventional immersion oils or so-called anti-Newton oils are used. Only after the photoemulsion has been treated in such a way - it can be dipped into the liquid or coated with it - is it brought into contact with the adhesive.
- the photo emulsion after removal of the film carrier film, can be provided with a protective layer, for example a protective lacquer, so that it is also protected against the action of aggressive liquids or sharp tools.
- a protective layer for example a protective lacquer
- a screen printing process can be used.
- optical filter structures which are impressed on the photoemulsion are preferably so-called barrier filters which are used for the spatial representation. It is understood that the features mentioned above and those yet to be explained below can be used not only in the specified combinations but also in other combinations or alone, without departing from the scope of the present invention.
- FIG. 1 shows how a photographic film is applied to a carrier substrate
- FIG. 5 shows the process of heating the film carrier film by means of the use of a movable heating rail.
- the carrier substrate 1 used is a glass substrate, which generally has the shape of a flat cuboid. On its underside, the carrier substrate 1 is here provided with an antireflection coating 2, but this coating is not mandatory and serves only for viewing comfort.
- An adhesive 3 is applied to the upper side of the carrier substrate 1. As the adhesive 3, a viscous adhesive of monomers which polymerize and cure under irradiation with ultraviolet light can be used.
- a photographic film comprising a film support film 4 and a photo emulsion 5 applied to the film support film with the side of the film on which the photoemulsion 5 is located with the adhesion agent 3 brought into contact.
- the optical filter structures are impressed into the photoemulsion 5 by exposure, development and fixation. This can be achieved by ke is exposed and imaged on the film. Examples of such optical filter structures are shown in FIGS. 2 a) -c).
- the optical filter structure consists of opaque - black - filter elements and transparent - white - filter elements, which are arranged at regular intervals to each other.
- a liquid can be applied to the photoemulsion or its surface, which penetrates into pores or openings in the photoemulsion and at least partially closes them. This ensures that the adhesive is prevented from penetrating too deeply into the pores, which brings advantages in further processing.
- an immersion oil may be used as the liquid.
- the adhesive 3 is then distributed between the film and carrier substrate 1, in which the film is pressed against the carrier substrate 1 by rolling a roller 6 onto the film at a predetermined contact pressure and at a predetermined feed rate of the roller 6.
- the contact pressure must not be so strong that the film carrier film is overstretched, which can lead to changes in the filter structure, which can lead to a uselessness of the filter: Vary the distances of the transparent filter elements shown in Fig. 2, the effect of spatial perceptibility without aids significantly disturbed.
- the contact pressure is therefore in a range between one and 20 kPa, depending on the ambient temperature and the viscosity of the adhesive agent 3.
- the feed rate is chosen in coordination with the selected pressure, it is usually in ranges between 0.5 and 20 mm / s when the ambient temperature is equal to room temperature. At other temperatures, higher or even lower speeds and / or pressures may be appropriate.
- the pressure must not be too low, since otherwise the adhesive 3 is not sufficiently distributed on the carrier substrate 1.
- the thickness of the layer of the adhesive 3 should be approximately between 10 ⁇ m and 30 ⁇ m.
- a permanent bond between the carrier substrate 1 and the photoemulsion 5 is produced by curing the adhesive 3.
- the adhesive agent layer 3 shown in Fig. 3 may be cured by irradiation with light from UV light sources 7.
- the necessary exposure time depends on the one hand on the thickness of the layer of the adhesive agent, on the other hand also on the temperature, which is ideally 22 9 C and should not drop well below 10 0 C, the illuminance of the UV light, and of the Thickness of the carrier substrate 1 and its Absorbency in the ultraviolet range. If, for example, 6 mm thick float glass is used as carrier substrate 1, the exposure time is approximately 30 s at room temperature.
- the film base film 4 which forms another unnecessary layer through which the light must pass and which also adversely affects the brightness, does not necessarily remain on the photoemulsion 5.
- the film carrier film 4 is thermally separated from the photo emulsion 5 and removed therefrom.
- the film carrier film 4 itself must be heated so that the photoemulsion 5 can detach from it.
- the film carrier film 4 is not heated too much, otherwise the photo emulsion 5 would be completely warmed up. This could result in attempting to remove the film carrier sheet 4 to destroy the photoemulsion 5. For example, overheating could cause the photoemulsion 5 also to detach from the layer of adhesive 3, leaving only residues thereon.
- FIGS. 4 and 5 Two ways in which one can successfully separate film carrier film 4 and photo emulsion 5 are shown in FIGS. 4 and 5.
- the heating plate 8 radiates downward in the direction of the film carrier film 4 heat, characterized by the thick, downwardly pointing arrows.
- the distance of the heating plate and its temperature, and the duration of heating are chosen depending on the thickness of the film carrier film 4 so that although the film carrier film 4 itself heated sufficiently, but not the underlying layer of the photoemulsion 5.
- the latter may be at most in Heat a very thin, near-surface layer to the extent that its - set by the heating - elastic state does not lead to tearing in the photoemulsion layer itself. This is illustrated by the small arrows pointing to the surface of the photoemulsion 5.
- FIG. 1 Another possibility, with which the heating can be controlled even better, is shown in FIG.
- a heating element configured as a heating rail 9 is guided over the film carrier film 4 with a surface emitting heat in the direction of the film carrier film 4 at a predetermined distance.
- a heating rail and a heating wire or a similar heating element can be used, and the heating element does not have to be passed to the support film, as well as the composite system can be passed to a stationary heating rail 9. It is only important that between film carrier film 4 and heating rail 9 a relative movement as shown in Figure 5 and by pointing to the right, from the heating Rail 9 outgoing arrow shown, takes place.
- the feed rate is in turn chosen depending on the above-mentioned parameters so that the film carrier film 4, although heated, the underlying layer of the photoemulsion 5, however, at most only in a thin, near-surface layer.
- an optimal temperature regime can be set in a simple manner under otherwise constant conditions so that, immediately after the heating rail 9 has been guided past the film carrier film 4, the film carrier film 4 moves behind the heating rail 9 in the direction of movement peel off, as shown by the arrow pointing out vertically from the film carrier film 4.
- an optical filter for example a barrier filter for spatial representation
- a thin, firmly cured adhesive layer is present on the carrier substrate 1 of a thickness between about 10 microns and 30 microns, on which the photoemulsion 5, which are embossed the optical filter structures adheres.
- This adhesion to the cured adhesive 3 corresponds at least to the adhesion, as it had the photo emulsion 5 previously on the film carrier sheet 4. It is in any case smudge and scratch resistant, as long as no sharp or angular objects against the layer of photo emulsion 5 are used.
- the photographic emulsion 5 is provided with a separate protective layer after removal of the film carrier film 4, for example with a special lacquer which can be applied by a screen printing method, the filter structure can even be protected against sharp-edged influences or against aggressive liquids.
- optical filters produced in this way can be separated much more easily and reliably, for example by means of glass cutters, than is possible in the prior art.
- the risk of breakage and injury is thus significantly reduced.
- the contrast is significantly improved both in two- and three-dimensional representations.
