Hereinafter, with reference to the accompanying drawings will be described in detail the advantages, features and preferred embodiments of the present invention.

2A is a cross-sectional view of a first embodiment of a reflective bonded image panel according to the present invention. As shown in FIG. 2A, a first embodiment of a reflective junction image panel according to the present invention is a transmissive diffusion medium between a pair of substrates composed of a dislocation element 10 and a back element 20. (40, transmissive diffusing medium) is injected, and the dislocation element and the rear element are sealed while the gap between the substrates is maintained by the sealing material 30. In addition, one side of the substrate of the back element 20 is formed so as to form a reflective mirror having a reflective layer 20b for reflecting most of visible light (visible light reflectance of about 80% or more) and a protective layer 20a for protecting the reflective layer. do. Preferably, the visible light reflectance of the reflective layer 20b is 15 to 95%. When the reflectance of the reflective layer 20b is 15% or less, the reflection efficiency is reduced and the brightness of the screen is weakened. In the present technology, reflectors such as an optical surface mirror or a metal reflector used as a reflective layer have a reflectance of 95% or more. Because it is impossible to have. The preferred reflectance range (15 to 95%) of the reflective layer is of course applied to the reflective layer to be applied to the following various embodiments.

On the other hand, the transmissive diffusion medium 40 is surrounded by a pair of substrates consisting of the dislocation element 10 and the rear element 20, specifically, the transmissive diffusion medium is a cell made of a pair of substrates and a sealing material It is filled in and sealed. The spacing between the pair of substrates in which the transmissive diffusion medium 40 is filled is not limited, and is to be formed to 0.01 to 10 mm, preferably 0.1 to 1 mm. If the spacing between the pair of substrates is less than 0.01 mm, it is very difficult to inject the composition for the diffusion medium to form the diffusion medium 40 into the cells formed between the substrates, as well as the diffusion medium for the entire area of the substrate. It becomes difficult to form so as to have a uniform thickness. Also, when the distance between the pair of substrates is larger than 10 mm, the distance between the light rays reflected by the reflective layer 20b and the light rays reflected by the outer surface of the substrate of the dislocation element 10 is widened, so that the image projected on the screen is double or Overlapping three times makes it difficult to implement a clear image. Therefore, in order to facilitate the process of injecting the composition for the diffusion medium and to distribute the diffusion medium with a uniform thickness over the entire area of the reflective junction image panel, and to ensure the image quality of the projection image on the screen, The spacing between the rear element 20 substrate is to be formed to 0.01 to 10mm. In addition, the preferred range of the distance between the front element and the rear element substrate is also applicable to the various embodiments described below.

As the base material composed of the dislocation element 10 and the rear element 20 according to the present invention, a glass plate, a plastic sheet, a ceramic plate, and a metal sheet may be selected and used. Preferably, transparent or translucent glass or plastic material is used as the dislocation element 10. Specifically, in the case of using glass, various forms such as general transparent glass, translucent glass, etched glass, colored glass, tempered glass, laminated glass, wired glass, heat absorbing glass, reflective glass, ultraviolet absorbing glass, metal coated glass, or mirror glass Glass can be used. In addition, when plastic is used, it is not only a transparent or translucent acrylic resin sheet, a PET resin sheet, a polycarbonate sheet, but also a general PET film and a heating wire. It can be used without limitation, such as a special film such as a blocking film, a UV blocking film, a metal coated film, a Saran film made by Dow Product or an Aclar film made by Allied Product. In addition, when using a metal, it is possible to use a metal of various materials, such as aluminum, copper, iron or stainless steel.

In addition, the substrate on one side of the pair of substrates composed of the dislocation element 10 and the rear element 20 may be formed in one or more layers. That is, functional surface treatments can be performed on the outer surface of the substrate constituting the cells of the bonded image panel by using a plurality of substrates overlapping each other. Functional surface treatments include non-glare treatments to prevent glare from ambient lighting and sunlight, anti-reflection treatments to prevent light reflections from illumination and sunlight, and generation of static electricity. Anti-static treatment to remove, prism treatment to enhance brightness and selective absorption treatment to selectively absorb specific wavelengths. In addition, the surface treatment method may be a method of applying the functional coatings (functional coatings) to the surface or attaching functional films (functional films) using an adhesive.

The sealing material 30 according to the present invention serves to block the external environment while the transmission diffusion medium 40 maintains a constant thickness between the substrates. As the sealing material 30, a double-sided tape having a constant thickness is used, or polyvinyl butyral, epoxy resin, acrylic resin, and isobutylene, which are used in the manufacture of general multilayer glass or laminated glass, are used. (isobutylene), silicon (silicon) or polysulfide (polysulfide), etc. may be used, and frit, which is a low-temperature molten glass paste, may be used. Such a sealant has a kind having different characteristics such as moisture curability, heat curability, and photocurability, and may be selectively used according to the needs of a manufacturing process of the reflective junction image panel according to the present invention. On the other hand, the sealing material 30 is composed of a spacer material spaced apart from the first substrate and the second substrate by a predetermined distance, and an adhesive applied to the upper and lower portions of the spacer, and the adhesive is polyvinyl butyral and epoxy resin. Of course, any one selected from acrylic resin, isobutylene, isobutylene, silicon, polysulfide, and frit, which is a low temperature molten glass paste, may be used.

The transparent or translucent diffusing medium 40 according to the present invention comprises at least one water-soluble polymeric material which is soluble in water to form a transparent solution, hydrophilic and highly dispersible in water. A light cure is a medium comprising a composition comprising at least one selected photocurable hydrophilic monomer, a solvent and a photoinitiator that reacts with the photocurable hydrophilic monomer to cause a polymer reaction. . The diffusion medium 40 realizes an image by uniformly diffusing the projection image while being transparent or translucent. The water-soluble polymer material is 0.5 to 35% by weight based on the total weight of the composition, the photocurable hydrophilic monomer is 31 to 98.5% by weight based on the total weight, and the photoinitiator is based on the total weight of the photocurable hydrophilic monomer. To 0.1 to 5% by weight. In addition, the solvent is to be 0.5 to 35% by weight based on the total weight of the composition. As the water-soluble polymer material, at least one selected from derivatives of polymethylvinyl ether and polymethylvinyl ether may be used. As the photocurable hydrophilic monomer, hydroxyethyl acrylate and hydroxyethyl methacrylate ), Hydroxypropyl acrylate, hydroxypropyl methacrylate, dimethyl acrylamide, methoxy polyethyleneglycol methacrylate and methoxy polyethylene glycol acrylate At least one selected from (methoxy polyethyleneglycol acrylate) may be used. In addition, as a photoinitiator, benzophenone, ethyl 4- (dimethylamino) benzoate, benzyl dimethyl ketal, 1- (4- (2-hydroxyethoxy) -phenyl) -2-hydroxy-2-methyl-1 At least one selected from -propane-1-one, 2-hydroxy-2-methyl-1-phenyl-propane-1-one, trimethyl benzoyl diphenyl phosphine oxide and bisacrylphosphine oxide can be used, and as a solvent, May be any one selected from pure water, an organic solvent, and a mixture of pure water and an organic solvent. Such a diffusion medium is transparent or translucent and uniformly diffuses the projection image to realize the image.

On the other hand, the transparent or translucent transparent diffusion medium 40 according to the present invention is selected from at least one water-soluble polymer material, methoxy polyethyleneglycol methacrylate and methoxy polyethyleneglycol acrylate A composition consisting of at least one selected methoxy monomer, at least one selected photocurable hydrophilic monomer, a solvent and a photoinitiator may be obtained through photocuring. At this time, the water-soluble polymer material is 4 to 40% by weight, 7 to 50% by weight relative to the total monomer, 7 to 20% by weight based on the total weight of the composition. If out of the range, the diffusion characteristics of the diffusion medium are insufficient. In addition, the hydrophilic methoxy monomer serves to improve the diffusion properties of the diffusion medium, 20 to 43% by weight based on the total weight of the composition. If less than 20% by weight or more than 43% by weight of methoxy monomer is used, the diffusion characteristics of the diffusion medium will be insufficient. Since the photocurable hydrophilic monomer should be easily dispersed in water to maintain a transparent state so as not to affect the transparent aqueous solution of the water-soluble polymer material, a hydrophilic property is preferable, and a monomer having high dispersibility in water is preferable. Moreover, it is preferable that a monomer is not polyfunctional. If a multifunctional monomer is used, the adhesion to the substrate of the bonded transmissive panel is affected. That is, the multifunctional monomers are cross-linked with each other when polymerized by the initiator, thereby increasing a volume reduction rate that becomes smaller than the volume of the original mixed composition. Therefore, as the medium in the cell consisting of the substrates 10 and 20 and the sealing material 30 of the reflective junction image panel undergoes a polymer reaction, the shrinkage increases as a result of the polymer reaction, thereby separating the medium from the substrate of the cell. As the peeling phenomenon occurs, the quality of the product is degraded as the bonded image panel, which makes it difficult to use. As the photocurable hydrophilic monomer, selected hydrophilic monomers which are dispersible in water and undergo a polymer reaction by a photoinitiator can be used, and 10 to 50% by weight in comparison with the hydrophilic methoxy monomer to maintain the diffusion characteristics of the diffusion medium. Keep the range. On the other hand, the photoinitiator can be used any photoinitiator that can react with the photocurable hydrophilic monomer to cause a polymer reaction, and generally about 0.1 to 5% by weight, preferably 0.2 to 4% by weight for each monomer. do.

The manufacturing process of the reflective junction image panel of FIG. 2A is described below.

First, the dislocation element 10 is formed of a chemical etching glass pane which is anti-glare treatment. In addition, the reflective layer 20b is formed on the surface of the back element 20 and then formed as an optical surface mirror having a protective layer 20a formed thereon.

Next, the substrate of the dislocation element 10 and the rear element 20 are cut to a certain size, and a cell is formed of a pair of the substrate and the sealing material 30 formed of the dislocation element and the rear element. Then, the composition to be used as the diffusion medium 40 is injected into the empty space of the formed cell and then sealed.

When the sealed panel is exposed to ultraviolet rays, electron beams, or visible light for a predetermined time, the composition for the diffusion medium in the cell causes a polymer reaction. After the polymer reaction is completed, the panel becomes a laminated image panel that realizes an image at room temperature.

When the image is projected on the panel manufactured by the above process with the projector, the reflective layer 20b of the rear element 20 can obtain an image of very bright and high brightness with a maximum of 20 gains, and the diffusion medium 40 This enables nano-scale ultra-high resolution and high-definition projection images that go well beyond the concept of pixels of several millimeters, which determines the resolution in a typical video display.

2B is a cross-sectional view of a second embodiment of a reflective bonded image panel according to the present invention. As shown in FIG. 2B, the second exemplary embodiment of the reflective bonded image panel according to the present invention includes a total reflection layer 20b having most of the visible light reflected on one surface of the substrate of the back element 20 in the form of a transparent film. It forms in the protective layer 20a, and the reflecting layer 20b is adhere | attached on the inner surface of the back element 20 by the adhesive layer 20c. Specifically, an oxide film, that is, a planar metal reflective sheet having a protective layer 20a formed thereon as a reflective layer 20b, is attached to one surface of the substrate of the back element 20 with an adhesive 20c to form a rear mirror element as a kind of reflective mirror. Can be. In addition, a reflective film coated with aluminum or silver on one surface of a polyethylene (PE) film, polypropylene (PP), or PET (PET) film may be attached to the adhesive layer 20c using the reflective layer 20b. As the metal reflective sheet, aluminum, copper, iron or stainless steel having a constant reflectance may be used.

The manufacturing process of the second embodiment of the reflective bonded image panel according to the present invention is performed in the same process as described above, and a detailed description thereof will be omitted.

On the other hand, when a temporary fixing adhesive is used as the adhesive 20c when the metal reflective sheet or the reflective film is adhered to the rear element 20, the composition for the diffusion medium 40 is polymerized by the exposure process, thereby completely curing. The back element 20 can be removed later. In this case, the reflecting layer 20b made of the metal reflecting sheet or the reflecting film becomes the rear element 20.

3 is a cross-sectional view of a third embodiment of a reflective bonded image panel according to the present invention, illustrating an embodiment of a reflective bonded image panel having an inclined surface. As shown in FIG. 3, the third embodiment of the reflective junction image panel according to the present invention is a reflective layer 20b having an inclined angle surface treatment instead of the flat reflective layer 20b (for example, a flat aluminum reflective sheet) shown in FIG. 2B. For example, aluminum reflective sheet) can be used. In this case, on one surface of the backing element 20, an aluminum film, that is, a protective layer 20a, is formed and attached to the aluminum reflector 20b, which is surface treated to form an inclination angle, by using an adhesive 20c to form a rearview mirror. The element 20 will be fabricated. Further, after forming a cell with a pair of substrates and the sealing material 30 composed of the transmissive dislocation elements 10 prepared separately, the composition for diffusion medium is injected and sealed in the empty space of the formed cell. As described above, when the surface of the reflective layer 20b is inclined, the projection distance can be shortened, thereby saving the projection space. Meanwhile, in addition to forming the reflective layer 20b to form an inclined angle as shown in FIG. 3, the surface treatment may be performed to form an uneven shape.

Upon completion of sealing of the panel, exposure to ultraviolet light, electron beam or visible light for a certain time cures the composition for diffusion medium in the cell. Meanwhile, an antiglare treatment 500 may be applied to one surface of the dislocation element 10 of the completed reflective image panel as a surface treatment. According to the third exemplary embodiment of the reflective junction image panel manufactured as described above, an image may be realized even at a location where a projection distance of a projector or a beam projector is short.

4 is a cross-sectional view of a fourth embodiment of a reflective bonded image panel according to the present invention, illustrating an embodiment of a reflective bonded image panel having a curved surface. One of the reasons that the screen of a theater forms a round curved surface is to make the projection light of the projector or the beam projector equal to the projection distance reaching the screen of the center and the projection distance on the left and right sides. Therefore, especially in the case of a large reflective junction image panel, when formed into a curved surface as in the fourth embodiment of the reflective junction image panel of the present invention, the central and left and right images have more uniform brightness.

In order to process the reflective junction image panel as a curved surface, the dislocation element 10 and the rear element 20 must be manufactured through an appropriate processing process. When glass or plastic is used as the dislocation element and the rear element, a reflective junction image panel having a curved surface may be manufactured by any one of the following curved processing processes. Hereinafter, each curved surface treatment process will be described with reference to FIGS. 5 to 7.

It is explanatory drawing of the curved surface process process using the metal plate mold | die. As shown in FIG. 5, when both the dislocation element 10 and the rear element 20 are made of glass (or an optical surface mirror) or a plastic material, a mold 600 having a required curvature and size is first made of a thick iron plate. After the production by cutting the glass or plastic to the same size as the mold 600 produced. Next, after placing the cut glass or plastic on the mold 600, it is left in the heating furnace by the heater 120 for a predetermined time so as to have a temperature range of the temperature at which the glass or plastic softens. Therefore, the glass or plastic on the mold softens on the mold and adheres to the mold so that the glass or plastic sheet has the same curvature and size as the mold, and when these are cooled at room temperature, the dislocation element 10 and the back element having a constant curvature ( 20) can be generated. The pair of substrates formed of the dislocation element 10 and the rear element 20 generated as described above also form a cell using the sealing material 30.

FIG. 6 is an explanatory diagram of a curved surface processing process using the coefficient of thermal expansion of a metal reflective sheet, showing an embodiment in which the reflective element 20b is adhered to the rear element 20 and the rear element is curved. In FIG. 6, a metal reflective sheet (such as an aluminum reflective sheet) is used as the reflective layer 20b, and a thermal adhesive film is used as the adhesive layer 20c.

First, the heat-adhesive film 20c is placed on one surface of the rear element 20 of glass material cut to a certain size, and then the aluminum reflective sheet 20b having the same size as the rear element 20 is placed thereon. Next, the trailing element 20 is passed through the laminator equipped with the roller 110 in the heating furnace heated by the heater 120. At this time, the heat-adhesive film 20c in contact with the glass softens and bonds the glass, which is the rear element 20, to the aluminum reflective sheet 20b, and because the thermal expansion coefficient of aluminum is higher than that of the aluminum reflective sheet 20b. ) Is thermally bonded to the glass 20 in an increased state. When the rear element 20 of the glass material to which the aluminum reflective sheet 20b is bonded is left at room temperature, the rear element 20 having a naturally curved surface is formed due to the force to which the stretched aluminum reflective sheet 20b returns to its original size. Will be. Apart from the curved rear element 20, the dislocation element 10 is curved through a process as shown in FIG. 5 and the like, and then a pair of substrates of the dislocation element and the rear element are formed using the sealing material 30.

7 is an explanatory diagram of a curved surface processing process using a change in vertical cooling air. As shown in FIG. 7, when the dislocation element 10 and the rear element 20 are both formed of a glass material, the glass is cut to an appropriate size and then softened in a heating furnace having a temperature range in which the glass softens. Let's do it. Next, when the air is constantly blown from the upper and lower portions of the softened glass 10 or 20, the tempered glass is formed. At this time, when the cool air 700 or more air is blown from the lower portion than the air blowing from the upper portion, the glass is curved by the temperature difference between the upper and lower portions of the glass 10 or 20. Since it becomes a kind of curved tempered glass, the dislocation element 10 and the rear element 20 of the reinforced glass material having a constant curvature are formed.

Meanwhile, the reflective junction image panel may be used in which nothing is filled in the empty space of the cell generated by the substrate of the dislocation element 10 and the back element 20. That is, the cell may be formed into an empty space only without the process of injecting and photocuring the composition for the diffusion medium. In this case, although the resolution and image quality of the reflective junction image panel including the diffusion medium are not as high, it is possible to realize a high brightness image.

An embodiment of manufacturing a reflective junction image panel according to the present invention is as follows.

Example 1
