[Detailed description of the invention] 33 Covering plate; 34 Light shielding part: 35 Another thin layer Lascou: 36 Another thin layer of Lascou; 37 Wide side: 38 Board: 39. Care agent: 40 Element (Element. Kδrper): 41 Surface; 42 Edge area: 43 Lamb: Specification Display device with display area and thin raster, and method for producing thin raster The present invention relates to a display device according to the first part of claim 1.

This type of display device is described in European Patent Application No. 208283 (this document is (considered to be known within the framework of the description). Thin layer rusk (with pleats) screen) fLamellenraster) divides the optical image and It has the effect of ensuring that the image of the object is completely visible only at a certain limited projection angle. . And even if you look at the image from an angle, you can't see it or it's only dark. can not see. In such cases, the observer sees alternating thin layers. It is only.

Here, the smaller the projection angle and the larger the distance from the viewer, the more the image The law applies that the image becomes clearer, but its brightness becomes weaker. The above European patent Application No. 208283 describes a louvered thin layer; In fact, it has been found that the stability is insufficient when the rotation speed is increased. won. This lack of stiffness in the thin layer often results in image distortion or Obfuscates the transition from visible to invisible layers of the image during rotation. Therefore the book The object of the invention is to create a thin lath with sufficient stability in all directions even at high rotational speeds. It's about providing a ku. Also, make sure that the thin layer does not vibrate, Furthermore, the thin layer raster can be manufactured separately from other components of the display, making it easier to assemble the display. The various advantages and improvements of the present invention which can be achieved in a satisfactory manner by Embodiments are set forth in the subclaims and drawing description.

A detailed explanation will be given below using the drawings.

Brief description of the drawing FIG. 1 shows a display area provided with individual spacers; Figure 2 is an enlarged view of a thin layer cast into one block; FIG. 3 shows a plan view, partially in section, of the different surface structures of a monolithic cast block. side view, FIG. 4 is a perspective view of one of the individual spacers made of transparent material; FIG. 5 is a partially cutaway perspective view of two spacers; FIG. 6 shows sections of a honeycomb-shaped lasku (grid) with metal spacers, Figure 7 shows the configuration in a rotating cylinder to improve the optical properties of Lascou. figure, FIG. 8 to FIG. 12 are diagrams showing various modified examples of Lascou; 13 to 15 are diagrams showing the combination structure of raster and image, Figures 16 and 17 are diagrams showing Lascous with modified optical parameters. .

A light source 1 is placed inside the cylinder 13 (FIGS. 1 and 7) on a plane passing through the axis 14 of this cylinder. A light source 16 and one image 15 provided with a transparent image 15 illuminated by In between is provided a lasque consisting of a thin layer 1a parallel to the axis 6?114. thin layer 1a are separated from each other by flat spacers 2a. The spacer is the axis 14 on a plurality of different planes orthogonal to each other. Mount the image directly within the lamina You can also do that.

The cylinder 13 is substantially transparent, but the inner or outer wall on the light source side is mirror-like. 1 The cylinder is rotated by a drive unit (not shown), so the image The display area formed by the 0 image and the raster that can be viewed from the surroundings. It is also possible to rotate the body (especially with an LCD or electroluminescent display) ), but in the case of a transparent image, the side opposite to the image of the light source 16 is shaded in any case. The scope of the present invention also includes a configuration that combines transmitted light and reflected light. Around the included cylinder 13, there is another cylinder (not shown) as a casing. It can also be provided as at least a dust shield.

Even when a strong centrifugal force is applied, the thin layers 1a are reinforced with each other through the spacer 2a. The spacer 2a is arranged in a sheet shape so that it will not be distorted laterally. In addition, below or above the observation plane substantially parallel to the spacer 2a. This has the effect of making it impossible to view the image from a certain angle. . This effect is similar to that of a thin layer 1a and therefore between the spacers 2a. depending on the distance and the distance from the observer.

FIGS. 16 and 17 show spacers 2k and 21 with different planar areas. As shown in FIG. It has a slope, which improves the quality of image reproduction when viewed diagonally from above. There is. Alternatively, in the case of a thin layer of 1 m, it forms an oblique angle to the image plane, and this This is intended to reduce blurring in the edge regions of the thin layer raster. child The angle to the image plane of a 1m thin layer of is determined by the desired distance from the observer. Involved. In other words, each 1m of lamina has a straight line between the observer's eye and each 1m of lamina. It should be on the line connecting .

In FIG. 2, an actuator is placed within a circle 813 similar in function and structure to that of FIG. There are thin layers 1c spaced apart by rill glass 2f. These thin layers is cast into an acrylic glass block 5a. This configuration allows thin laminated The star becomes extremely strong, and the spacer 2f does not limit the field of view. Forming the layer 2 and the thin layer 1 with silicone rubber increases heat resistance and reduces thermal expansion. Forming a thin layer with adhesive, which is thin and has good adhesion, makes manufacturing easier. Also, since there is no need to apply paint to the layer surface 3a, the effort of drying the paint is saved. can.

The thin layer 1c consists of a dark or black metal, as shown in the right part of the second section. Bu The surface of the lock 5a is flat and does not have any special structure, as shown on the right side. The light can be intentionally diffused or focused, as shown in the middle section. It may also have a surface structure 7, for example a plurality of glass beads.

On the left side of the image, the surface of the block 5a is provided with a coating 6 that weakens reflection. . This coating preferably has a polarizing effect. Usually there is only one type of table on the block surface. Only surface processing is applied, but for example, seeds such as the one shown in Figure 3 are applied to achieve a specific effect. Different surface treatments can also be applied.

In Figure 3, a glass ball is shown on the left, which is an acrylic glass ball. It is formed integrally with the lock 5b. Furthermore, next to it is an anamorphic (an A cross section of a block with an amorphic lens 9 is shown. This announcer The morphic lens is applied to the entire height of the thin layer Lascou or glass block 5b. It extends across the country. These lenses are formed in a convex shape. However, It is also possible to provide a concave structure. Next to it is a block with a Fresnel structure IO. There is a cross-sectional area of the lock 5b. This structure is a special parallel focusing of the light that passes through it. enable.

The main effect of the lens is that the glass absorbs various types of metal or metal oxide ions. It can also be obtained by having a dipping concentration. Show this next to it . Between the thin layers 1d, the acrylic glass in the left region is The central portion 12 is doped with ions at a significantly higher concentration than the central portion 12.

In the lateral region, the doping increases as it approaches the middle 12 of the two adjacent thin layers 1d. The density of ngllb is increasing. By doping method, the refractive index of glass is It is changed to form the refractive index as a lens. The central area 12 has a metal If ON is concentrated, it corresponds to a concave structure. The concentration is increased at the edge near the thin layer 1d. If it is raised, it corresponds to configuring the surface of the glass block 5b to be a convex surface.

On the left side of the glass block, the lamina 1e does not reach the surface of the block 5b. , its pressure end is covered with glass. This prevents corrosion of thin layers, but In some cases, light mixing may occur in the region between the glass surface and the edge of the thin layer 1d. There is. In the right-hand region, the thin layer 1d reaches the surface, which allows the two The individual images between the thin layers 1d are each clearly separated. Thin layer 1 and spacer 2 It may also be formed from polarizing foil, with adjacent foils canceling out each other's light. Since the light is polarized, the image 15 can be seen by an observer observing the thin layer 1 from an oblique direction. When they overlap, they immediately become dark. In this way, the thin layer 1 itself will be It can be transparent and does not absorb light like a black surface, so it absorbs light energy. - You can save some money.

Adjacent polarizing foils polarize in the same plane of polarization, so one polarizing foil can be lathed at the same time. When placed flat on top of the screen, or when the entire display area is surrounded by polarizing foil. In some cases (eg, as shown at 30 in FIG. 7), the desired optical darkening effect is obtained.

Such a polarizing foil can also be attached to a second outer cylinder, not shown. That should be obvious.

In FIG. 4, thin layer 1b substantially covers one side of glassy spacer 2b or 2c. The individual spacers 2b to 2c formed by coloring each have a spacer color. The surface 3a of the spacer 2c is attached to the surface 4a of the next spacer 2c on the opposite side to the surface 3a. They are pasted together one after another in a way that they can be attached. In this way, the spacer 2c is They are each separated from each other by one thin layer 1b.

In FIG. 5, one surface 4a is shown with some of the thin layers removed. Practically, The adhesive for joining the spacer 2c is colored dark. This allows the spacer to be attached. No need for additional coloring.

In the 6th section, a thin layer 1e consisting of metal, carbon laminated hard paper or synthetic resin and 1f are combined into one honeycomb raster with spacers 2e and 2d. It is. The spacing between the spacers is chosen as large as possible to increase the viewing angle. ing.

This type of honeycomb raster appears similar to the texture of rolled metal. Casting a raster that looks like 0 or 0 into a transparent compound This can be considered to be extremely strong. The spacer is straight In this case, for example, the wall thickness is 0.1 mm, the thin layer spacing is 6 mm, and the spacer spacing is Using a black-colored raster made of dieralumin, 10 mm long and 22 mm deep. can be done. Such a raster consists of pixels cut from a molded tube (bike separator). It can also be constructed from Such rascous are particularly useful for large display surfaces. I can stay.

The apparatus shown in FIG. 7 differs from the cylinder 13 in FIGS. 1 and 2 in that the polarizing foil 3 0, this polarizing sheet has an anti-reflection effect on the one hand and a flat surface on the image 15 on the other hand. This prevents the image from being seen through the cylinder 13 in the horizontal direction. in this observation direction In some cases, the light existing in the shadow of the cylinder 13 may be transmitted to the observer due to the polarization effect. becomes invisible. This prevents interfering light reflection effects. or Instead of or in addition to the polarizing foil, a light shielding portion 34 that performs the same role is provided. An appropriate dimension of the light shielding part is c:d/2=0.4 to 0.8 (preferably 0.4 to 0.8). 6]. Here, d is the width of the raster, and C is the depth of the shaded part or the cylinder. With respect to the outer circumference d×π of the zero cylinder 13, which represents the width along 13, the light shielding part is approximately It should be 8%.

The non-zero projection angle of the thin lasku or image necessarily reduces the viewing area. When the area is rotated, a light shielding section 34 is provided so that the viewer cannot see the image from the front when the image is still. A thin layer raster 35 is shown having a thin layer 36, which also has a thin layer 36. It is integrated into the cylinder 13 or is integrally connected thereto. This thin layer The raster 25 makes the image 15 difficult to see from vertically above, making it difficult for the viewer to see the image. The image must be viewed from the horizontal direction, which causes the image to be distorted due to a shift in the viewing angle. This eliminates the inconvenience of having to wait.

The spacers 2g and 2h according to the configuration of FIG. 8 and section 9 are entirely made of metal. Become. The transparent plate 32 is provided with a slot 31 into which a thin layer l is inserted. h is inserted. Of course, similar to plate 32, there is another slot on the opposite side. It is also possible to provide an attached plate, but this is not necessarily required, as shown in Figure 8. It's fine. In many cases, it is sufficient to have a configuration in which the cover plate 33 also does not have slots, as shown in the figure. be. Such a coating plate may include a reflection-attenuating coating 6 and/or a coating already described in FIG. It is meaningful to provide a surface treatment 1 such as an anamorphic lens 9. This structure As shown in the figure, because the spacers 2g and 2h are only partially provided, The amount of light absorbed by these spacers is small. If the cover plate 33 is removed, furthermore, This prevents visible afterglow effects on the viewer side of the plate material and improves darkening. You can make it as you like.

The thin layer 11 in FIG. It is provided in the slot 31a in the width surface 37. The slot 31a is a side milling cutter, formed by jet beam, laser beam, or plasma cutting; 38 using a corresponding mold. The slot 31a is made as thin as possible. The surface tension of the dye or paint must be extremely high in order to inject it into the slot. It must be very small. Of course, such a slot 31a is manufactured in advance. You can also insert a thin layer. This manufacturing method is particularly advantageous when the thin layer is Advantageous in the case of non-rectangular structures or structures with different dimensions .

Due to the geometrical angular ratio when the display area is rotated, the edge area 42 as shown in FIG. A thin spacer is provided in the area so that the projection angle in the edge area of the thin lasku is similar to that in the center. It is advantageous to make it smaller than that. The projection angle of the edge region is If the image is too large (compared to the diameter of the For example, in the configuration shown in Figure 17, the area may become blurry. Prevents blurry edges. Here, the formula a:tana/2=b holds true. where a is the spacing between the laminae, b is the depth of the laminae, and a is the desired projection angle. desire The new projection angle is 60°. a is determined by the distance between the viewer and the display device.

If the distance is more than 2 m, a thin layer spacing of about 1 mm is sufficient, so in this case b = 1.7 It will be 3mm. Of course, other conditions are also possible, for example, Shin-Etsu Polymer Co., Ltd. A foil [1VCFJ can be used.

By using the spacer 21 formed as an optical fiber shown in FIG. 11, the minimum projection angle can be It is possible to produce extremely compact thin-layer rasters with . optical fiber The totally reflective surface of the wafer has the same effect as the thin layer according to the invention. With such a configuration, Each optical fiber or each optical fiber can be individually controlled by its own light source. If this is done, digital image display can also be performed. Optical fiber is flexible Therefore, the joining position with the light source (not shown) can be arbitrarily selected.

Integrates with the display area by assembling raster individual light cubes 40 A transparent light cube (cubic lig htelements) The surface of 40 is first made reflective and then coated black. or colored with black adhesive and pasted in the direction of the arrow to A mosaic structure consisting of the tubes 40 is formed. Surface 4 facing the observer 1, the color and adhesive are removed and polished, so light can only pass through this surface. Not released.

The light is provided by a light emitting diode or small discharge lamp within the light cube 40 - preferably is emitted by a micro-halogen lamp. This lamp is abbreviated as 43 . The distance between the lamp and the surface 41 depends on the projection angle. Again, the individual display areas Since input can be controlled individually, digital image content can be displayed. La like this The light cube 40 may be made integrally with the lamp 43 by injection molding, or It is made by cutting a bar-shaped material manufactured in advance, and in that case, the lamp 43 is attached to this bar-shaped material. For example, if a display raster like this, in which blind holes are continuously cut out for Controlled through a computer, the storage capacity of a Combi21 allows you to store a large number of images. can be displayed while automatically replacing the display device. There is no need to make external electrical connections to the The same is true for LCD or electronics, where the computer will rotate with the raster. 9.Polarized light in translucent LCDs also applies to chromoluminescent displays. Foils can be selectively rotated to create a positive or negative display. Any one of the displays can be selected arbitrarily.

Rask the same surface as the space between the bike cells with an electroluminescent screen. If you make the area occupied by -, the image content will not be reduced. Scratch raster pixel This is advantageous because it can be directly integrated into the tube.

As shown in FIG. 24 and the transparent positive 20 are reinforced for convenient assembly and replacement. It turns out that Create such a combination structure in advance using various different images. It would be useful if it were possible to easily replace the image content on the display device by hand. A removable cover is provided on the rotatable part of a certain 0 display device, and this cover has a radius A take-out groove is provided in the direction to position and hold the above-mentioned combination structure in the axial direction. It is advantageous to do so. The base of this element is mirror-symmetrically formed. anti The radiation-absorbing coating 6 also prevents unwanted reflections in this configuration. Transparency and A translucent image is provided, which image preferably has a white light-diffusion layer on its back side. It is coated with a colored coating. This coating provides optimal color reproduction depending on the color of the light source. You can change it to make it achievable.

A similar combination structure is shown in Figure 14, but in the case of Figure 14, the rear transparent The plate 21c is formed to widen toward the end, and is integrally connected to the plate 21. This structure differs from the structure shown in FIG. 13 in this point. Light enters the lower surface of the plate 25 facing the annular light source 16a. A shooting hole 23 is provided. The entire outer surfaces (22, 26) of plates 21c and 25 It is reflective, so light is directed from the transparence 20 around the thin layer 24 to the front. The light is emitted only through the other transparent plate 21a. The advantage of this variant is that the light source This means that the display device cannot be slip-linked. A light emitting hole 27 is provided in the front part of the six plates 25, which can be driven without any adjustment. This hole is anti-reflective and allows the light passing through the thin layer 25 to be imaged. Project toward 20.

This causes a light mixing effect (mixing of transmitted light and incident light) at image 20. Therefore, the amount of light emitted from the light source 16a can be efficiently utilized. Board 2 1b and 21c preferably if the light source 16 also emits ultraviolet light; Shall block ultraviolet rays.

In the modification shown in FIG. 15, the projector 29 and the projection surface 19 are schematically shown. They rotate together with the laminar raster 24 lying on the axis of rotation 14. projector 29 can store multiple images that can be exchanged by remote control. projection surface 19 from the center to the side, the projector 29 can be aligned with the rotation axis 19. Since they can be placed as close together as possible, centrifugal force can be kept small. thin lath It is crucial that the coupe 24 is on the axis of rotation. This allows a small amount of light energy to be Only light energy is absorbed, which means that only a small amount of light energy is converted into heat. throw The shadow surface may, of course, be curved, and the projector must not be rotated with it. A slip ring-power supply is required.

The invention is in no way limited to the figures shown in the drawings and the description thereof; As a spacer, there are various variants of synthetic resin glass or mineral glass. Ru. In addition, another structure made of metal or synthetic resin may be provided as a spacer. can. Alternatively, the thin layer may be coated with paper or waves (known for example as catalyst structures). To form a honeycomb plate with a spacer consisting of a plate rolled into a cylindrical shape. can also be considered. Furthermore, the rascous and the image are slightly bent at least in the edge area. 8 Anti-reflection may also be provided by matte paint.
