Description

[Technical Field]

[0001] The present invention relates to an exhibition system and an exhibition method, and more particularly to a system and a method suitable for exhibiting objects with thin parts, such as plants. [Background technology]

[0002] Traditionally, exhibits such as plants and figurines have been displayed and appreciated in a variety of ways to enjoy their aesthetic and artistic merit. Plant exhibits in particular have a wide variety of display styles, from traditional methods such as bonsai and ikebana to the modern arrangement of ornamental plants as interior décor. In these exhibits, the shape and color of the exhibit itself are important elements, and the visual effect is enhanced by appropriately positioning and setting the environment according to the exhibit.

[0003] Lighting technology has also been widely used to enhance the visual impact of exhibits. Appropriate lighting can emphasize the colors and textures of exhibits and create a three-dimensional effect through shadow effects. In particular, artificial lighting plays an important role in plant exhibits to compensate for the lack of natural light and promote healthy plant growth.

[0004] Against this background, for example, Patent Document 1 proposes a plant lighting device for plant appreciation. This plant lighting device has a base on which a plant is placed, and a light source unit is disposed above the base. The light source unit illuminates the plant placed on the base. Irradiating the plant with light from the light source unit promotes plant growth and improves the plant's aesthetic appeal. Patent Document 1 also discloses a modified example in which the light source unit is disposed behind the plant as viewed from a position where an observer would normally observe (see FIG. 6). With this configuration, the plant is illuminated from behind, resulting in an effect of highlighting the entire plant. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Laid-Open No. 2009-17827 Summary of the Invention [Problem to be solved by the invention]

[0006] However, conventional plant lighting devices are merely technologies aimed at promoting plant growth and improving the aesthetic appeal of plants through lighting, and therefore, no consideration has been given to new visual effects for exhibits in the prior art.

[0007] In particular, there has been no exhibition technology capable of realizing unprecedented and unique visual expressions for exhibits of natural objects such as plants. In conventional exhibition methods, the shape and color of the exhibit itself are the primary viewing elements, and no consideration has been given to new visual effects, for example, by combining the exhibit with the background. Furthermore, even when devising backgrounds to enhance the visual effect of exhibits, this has been limited to simple decorations and color adjustments, and no technological approaches have been adopted that would create unprecedented visual phenomena through the interaction between the exhibit and the background.

[0008] Therefore, a main object of the present invention is to provide an exhibition technique that can realize novel visual effects. [Means for solving the problem]

[0009] After extensive research into ways to solve the above problems, the inventor of the present invention discovered that by installing a matrix display device such as an LED display behind an exhibit and irradiating the exhibit with strong light from this display device, the optical effect brought about by the interaction between the exhibit and the display device makes the exhibit appear as if it were a digital image composed of pixels when viewed from the front. Based on this discovery, the inventor then realized that a novel visual effect not previously seen could be achieved, and completed the present invention. Specifically, the present invention has the following configuration or steps.

[0010] A first aspect of the present invention relates to an exhibition system. The exhibition system according to the present invention includes a matrix display device and a pedestal. A matrix display device is a device for displaying images, whose display screen is composed of a plurality of pixels arranged in a matrix. Examples of matrix display devices include LED displays, liquid crystal displays, organic electroluminescence (EL) displays, and plasma displays. The pedestal is a structure or portion provided in front of the display screen of the matrix display device and used to place an exhibit. The pedestal may be any structure with a predetermined height as long as it is capable of placing an exhibit on it. For example, the pedestal may be a flat portion with no substantial height (thickness) and marked with a mark for placing an exhibit on it, or a portion formed with a recess for placing an exhibit on it. In other words, the pedestal may be any structure or portion intended for placing an exhibit on it. Furthermore, the exhibition system according to the present invention does not necessarily have to include the exhibit itself as a component, or it may be thought of as including the exhibit itself as a component. Furthermore, the exhibits include natural objects such as plants or rocks, processed natural objects such as preserved greenery, preserved flowers, insect specimens, or stuffed animals, and man-made objects that imitate natural objects such as fake greenery (artificial plants), artificial flowers, and artificial stones, as well as various other man-made objects such as art objects such as sculptures and pottery, figures, and industrial products such as home appliances and automobiles.

[0011] The above configuration allows multiple optical effects to interact with each other to create a unique visual effect, as if the exhibit were composed of the pixels of a digital image. This visual effect is referred to herein as "pixelation" of the exhibit. Specifically, first, diffraction occurs when light passes through the edges of thin parts of exhibits such as plants (e.g., stems and leaves of grass), causing the light to bend slightly as it travels. Second, the high-intensity light from the matrix display device is thought to cause a glare phenomenon, in which the intense light obscures the shadows of the exhibits. This occurs because excessively strong light overstimulates the visual cells, making it difficult for the brain to recognize weak information such as the shadows of adjacent exhibits. Third, these optical effects are thought to cause the lines of the exhibit to become identical to the pixel pitch of the matrix display device when the thickness of the lines is comparable to or thinner than the pixel pitch, making it appear as if parts of the exhibit are transparent or disappear. This results in the pixelated appearance of the exhibit. Furthermore, these optical effects can be observed not only by human vision but also by photography, so they are objective optical phenomena and not simply optical illusions.With these complex optical effects, the present invention can realize modern and artistic exhibition expressions that differ from conventional displays using simple lighting.

[0012] The display system of the present invention may further include a plant as an exhibit placed on the pedestal. It is preferable for the plant to have thin leaves and stems with moderate translucency. The characteristics of such plants allow the above-mentioned optical effects (diffraction, glare, and integration with pixel spacing) to occur more effectively, resulting in a clearer transparency or disappearance effect due to the interaction between the plant's details and the pixel pattern of the matrix display device. In particular, the pixelated visual effect unique to the present invention is more likely to appear when the plant's line thickness is comparable to or thinner than the pixel spacing of the matrix display device.

[0013] In the exhibition system according to the present invention, the pedestal preferably has a height sufficient to support the exhibit so that the exhibit at least partially overlaps the display screen of the matrix display device when viewed horizontally. As long as the height of the support surface for the exhibit can be ensured, the pedestal may be installed on the floor or on a wall. By appropriately setting the height of the pedestal in this manner, the positional relationship between the lines of the exhibit and the pixel spacing of the matrix display device is optimized when a viewer views the exhibit from the front, thereby improving the transparency effect of the exhibit due to the optical effect described above. Furthermore, by making the height position of the exhibit adjustable, it is also possible to adjust the degree to which the above-mentioned combined optical effect is manifested.

[0014] In the exhibition system of the present invention, the pedestal is preferably located within 500 mm of the display screen of the matrix display device. By locating the pedestal within this distance, the high-intensity light from the matrix display device can sufficiently reach the exhibit, appropriately generating effects such as shadow obscuration of the exhibit due to the glare phenomenon and light wraparound effects due to the diffraction phenomenon. It also enables viewers to view the pixelated exhibits at a natural viewing angle.

[0015] In the exhibition system of the present invention, the matrix display device is preferably an LED display. Because LED displays can emit light at high brightness, they can effectively create glare and diffraction effects on exhibits, making it easier to achieve optical effects that obscure shadows on the exhibits. Furthermore, because LED displays can independently control the brightness and color of each pixel, they can generate optimal light patterns according to the shape and layout of the exhibits, and easily adjust the relationship between pixel spacing and the thickness of the lines on the exhibits.

[0016] In the exhibition system of the present invention, the matrix display device preferably displays a grid image on the display screen, which displays some pixels in black at predetermined intervals. Note that "black display" refers to the following actions depending on the type of pixels (display elements) constituting the matrix display device. For example, in the case of an LED display, it means turning off pixels designated for black display, while in the case of an LCD display, it means blocking backlight light from pixels designated for black display. This grid image adjusts the effective pixel spacing, making it easier to optimize the effect of integrating the line thickness of the exhibit. Specifically, in a high-resolution matrix display device, intentionally displaying pixels in black at regular intervals makes it possible to artificially create pixel spacing appropriate for the transparency / disappearance effect of the exhibit. This further emphasizes the above-mentioned complex optical effects and more clearly realizes the visual effect of the exhibit pixelating.

[0017] In the exhibition system according to the present invention, the display screen of the matrix display device may be divided into a graphic drawing area and a viewing area. The graphic drawing area is an area where a predetermined graphic image is displayed and where exhibits do not overlap when viewed horizontally. The viewing area is an area where exhibits at least partially overlap when viewed horizontally. In this way, the positions and heights of the matrix display device and the pedestal are adjusted so that the display screen of the matrix display device has a graphic drawing area where exhibits do not overlap when viewed horizontally and a viewing area where exhibits overlap. With this configuration, it is possible to display normal images in the graphic drawing area while pixelating the exhibits in the viewing area.

[0018] A second aspect of the present invention relates to an exhibition method. The exhibition method of the present invention includes placing an exhibit in front of a display screen of a matrix display device (exhibition step) and displaying an image on the matrix display device (display step). In the exhibition step, the exhibit may be placed on a pedestal provided in front of the display screen of the matrix display device. The exhibition step and the display step may be performed in any order, and either step may be performed first. [Effects of the Invention]

[0019] The present invention provides an exhibition technology that can realize novel visual effects, particularly by using light from a matrix display device that is transmitted through or reflected from an exhibit, making it possible to provide new artistic expressions in which the exhibit and the background image are integrated.

[0021] Hereinafter, embodiments of the present invention will be described with reference to the drawings. The present invention is not limited to the embodiments described below, and includes appropriate modifications of the embodiments described below within the scope obvious to those skilled in the art.

[0022] Referring to FIG. 1, an exhibition system 100 according to a first embodiment of the present invention will be described. As shown in FIG. 1, the exhibition system 100 includes a matrix display device 10 and a pedestal 20. The exhibition system 100 may further include an exhibit 30 placed on the pedestal 20 as a component thereof. The matrix display device 10 is a display capable of displaying a predetermined image. As shown in FIG. 1, in the first embodiment, the matrix display device 10 has a vertically elongated shape. Specifically, the matrix display device 10 is configured such that its vertical length is greater than its horizontal length. The matrix display device 10 is disposed behind the pedestal 20 and the exhibit 30 from the viewpoint of a viewer of the exhibit 30. In this embodiment, the matrix display device 10 is attached to a wall surface perpendicular to the floor. Meanwhile, the pedestal 20 is disposed in front of the display screen of the matrix display device 10, and the exhibit 30 is placed on its top surface. The exhibit 30 is placed on the pedestal 20 and viewed by a viewer against the background of the image displayed on the matrix display device 10.

[0023] The matrix display device 10 is a display device whose display screen is composed of a plurality of pixels arranged in a matrix. In this embodiment, an LED display is used. The matrix display device 10 has a plurality of panels 11, each of which has a plurality of pixels 12 arranged thereon. Each pixel 12 is provided with a light-emitting element 13, and an image is displayed by the light emitted by the light-emitting element 13. In this embodiment, the panel 11 is rectangular, e.g., 600 mm x 337.5 mm. However, the size of the panel 11 is not limited to this. A plurality of panels 11 are combined horizontally and vertically to form the entire display screen of the matrix display device 10. The pixels 12 are arranged in a regular matrix (rows and columns) on each panel 11. Examples of the spacing (pixel pitch) between the pixels 12 are 0.78 mm, 0.9 mm, 1.8 mm, and 2.5 mm. The pixel pitch affects the appearance of the pixelation phenomenon of the exhibit 30, which will be described later. An appropriate pixel pitch can be selected depending on the degree of the phenomenon that the viewer wants to see. The light-emitting elements 13 are LED elements, and for example, LED chips of three colors, red (R), green (G), and blue (B), are combined to form one pixel 12. This allows the color and brightness of each pixel 12 to be controlled independently, making it possible to display a full-color image. In particular, by lighting up all of the red (R), green (G), and blue (B) light-emitting elements 13, the pixel 12 can emit white light. It is also possible to use a combination of LED chips of four colors, red (R), green (G), blue (B), and white (W), as the light-emitting elements 13.

[0024] The matrix display device 10 is not limited to an LED display. For example, a liquid crystal display can also be used as the matrix display device 10. When a liquid crystal display is used, liquid crystal cells are provided instead of the light-emitting elements 13, and light from a backlight is controlled by the orientation state of the liquid crystal cells to display an image. Alternatively, an organic EL display, a plasma display, an electronic paper display, or the like can also be used as the matrix display device 10. Whichever display device is used, it is important that the pixels 12 are arranged in a matrix and that each pixel 12 can be controlled independently. However, in order to achieve the effects of the present invention, it is preferable that the matrix display device 10 be capable of emitting light with high brightness, and from this perspective, an LED display is particularly suitable.

[0025] The pedestal 20 is a structure for placing the exhibit 30. In this embodiment, the pedestal 20 is installed on the floor and is formed as a structure with a predetermined height. The exhibit 30 can be stably placed on the top surface (mounting surface) of the pedestal 20. The height of the pedestal 20 is adjusted appropriately depending on the type and size of the exhibit 30, the size of the matrix display device 10, etc. For example, it is preferable that the height from the floor to the top surface of the pedestal 20 be set in the range of 200 mm to 1000 mm. The material of the pedestal 20 is not particularly limited, and wood, metal, resin, stone, etc. can be used. The shape of the pedestal 20 is also not particularly limited, and various shapes such as a rectangular parallelepiped, a cylindrical shape, or a polygonal prism can be adopted. The pedestal 20 may be formed as a single structure or may be formed by combining multiple members. Furthermore, the pedestal 20 may be fixed to the floor surface or may be movable. The pedestal 20 may also be height-adjustable.

[0026] The exhibit 30 is an object placed on the base 20 and is an object to be appreciated. In this embodiment, a plant 31 is used as the exhibit 30. The plant 31 is placed on the base 20 in a pot 32. Plants 31 that are particularly suitable for the present invention have thin leaves and stems. Appropriate translucency is also effective. Specifically, plants with stems and leaves with a thickness of approximately 0.5 mm to 3 mm are suitable. Examples of such plants 31 include herbaceous plants, ornamental plants, bonsai, and flower arrangements. More specifically, pine plants (black pine, red pine, etc.), rush plants (rush, etc.), ferns (bracken, fern, etc.), grass plants (Japanese pampas grass, Korean grass, etc.), narrow-leaf ornamental plants (asparagus, rosemary, etc.), coniferous trees (cedar, cypress, spruce, etc.), Asteraceae plants, caprifoliage plants, deciduous trees (zelkova, plum, persimmon, weeping cherry), etc. are particularly suitable. These plants have many thin stems and leaves, which, in relation to the pixel spacing of the matrix display device 10, can effectively produce the optical effect unique to the present invention. In particular, it is preferable that the exhibit 30 has linear portions that are the same as or thinner than the pixel spacing of the matrix display device 10.

[0027] The exhibit 30 is not limited to living plants, but may be preserved flowers, dried flowers, artificial plants, etc. Furthermore, the exhibit 30 is not limited to plants, but may be other objects having thin parts, such as sculptures, crafts, figurines, wire art, etc. The exhibit 30 should preferably have linear parts that are as thin as or thinner than the pixel spacing of the matrix display device 10.

[0028] Furthermore, the position and height of the support surface of the pedestal 20 for the exhibit 30 are adjusted so that the exhibit 30 at least partially overlaps the display screen of the matrix display device 10 when viewed horizontally. Specifically, the height of the pedestal 20 is set so that the height of the display screen of the matrix display device 10 coincides with the height of the exhibit 30 placed on the pedestal 20. For example, if the matrix display device 10 is installed 100 mm above the floor, the height of the pedestal 20 is adjusted so that the overall height, including the exhibit 30, overlaps with that position. This height setting optimizes the positional relationship between the thin linear portions of the exhibit 30 and the pixel array of the matrix display device 10, effectively achieving the pixelated effect of the exhibit 30 due to the optical effect described below. In particular, it is most preferable to set the position and height of the support surface of the pedestal 20 so that the entire exhibit 30 placed thereon fits within the display screen of the matrix display device 10.

[0029] Furthermore, the base 20 is preferably located within 500 mm from the display screen of the matrix display device 10. More specifically, the shortest distance from the base 20 to the display screen of the matrix display device 10 is preferably set in the range of 0 to 500 mm, and more preferably in the range of 50 to 400 mm or 100 to 300 mm. By placing the base 20 within this distance range, high-intensity light from the matrix display device 10 can sufficiently reach the exhibit 30, appropriately generating effects such as the shadow obscuring effect of the exhibit 30 due to the glare phenomenon and the light wraparound effect due to the diffraction phenomenon. If the distance is less than 100 mm, the exhibit 30 may be too close to the matrix display device 10 and may be thermally affected. On the other hand, if the distance exceeds 500 mm, the light intensity tends to be insufficient, resulting in an insufficient pixelation effect. A particularly suitable distance range is 200 mm to 350 mm, which provides a stable pixelation effect. Furthermore, this distance setting allows the viewer to view the exhibit 30 at a natural viewing angle.

[0030] Next, the pixelation phenomenon of the exhibit will be explained with reference to Figure 2. Figure 2 shows a schematic diagram of the pixelation phenomenon of the exhibit (plant). This phenomenon is a complex optical phenomenon that occurs as a result of the interaction of multiple optical effects.

[0031] As shown in Figure 2, when high-intensity light is irradiated from a matrix display device, multiple optical effects occur simultaneously in the thin parts of a plant (stems and leaves). First, diffraction is thought to occur when light passes through the edges of thin parts of a plant. Diffraction is a physical phenomenon in which light bends around the edges of obstacles, and occurs due to the relationship between the light's emission range and the size of the obstacle. As light bends around the edges of the plant, a small amount of light reaches areas that should be in shadow. Second, glare is thought to occur when high-intensity light from a matrix display device obscures the shadowed parts of the plant. Glare occurs when excessively strong light overstimulates visual cells, making it difficult for the brain to recognize weak information about the adjacent dark areas (in this case, the plant's shadow). This phenomenon is similar to the phenomenon in which a person cannot see the surrounding scenery when looking directly at a car's headlights at night. In other words, this phenomenon is more pronounced when the stems or leaves of a plant are thinner than the area where the light-emitting elements (LED pixels) are continuously lit and the light-emitting elements are spaced far apart. In the present invention, the high-brightness light emitted by the matrix display device significantly reduces the visibility of the shadow areas of the plants. Third, when the thickness of the plant's lines is the same as or thinner than the pixel pitch of the matrix display device, it is believed that the phenomenon of the plant's lines becoming one with the pixel pitch occurs. Specifically, this effect of becoming one with the pixel pitch is most pronounced when the thickness of the plant's stems and leaves is within the range of approximately 0.5 to 1.5 times the pixel pitch. For example, when the pixel pitch is 2.5 mm, it is believed that the appropriate effect can be achieved when the thickness of the plant's lines is within the range of approximately 1.2 mm to 3.75 mm.

[0032] These combined optical effects create a phenomenon in which parts of the plant appear to become transparent or disappear. As shown in Figure 2, the visual effect is such that light from the matrix display in the background is transmitted through the thin stems and leaves of the plant. This results in a unique visual effect in which the plant appears to be composed of pixels in a digital image, a phenomenon referred to herein as "pixelation" of the exhibit.

[0033] To effectively create the pixelation effect of exhibits, it is recommended to adjust the color and brightness of the image displayed on the matrix display device. White light is the most effective color. Because white light contains all wavelengths of visible light, it uniformly generates diffraction and maximizes the plant transparency effect. White light also easily achieves the highest brightness and effectively creates glare. Note that white light refers to light that contains a balanced range of all wavelengths of visible light (approximately 380 nm to 780 nm) and is not limited to strict pure white. For example, light with a color temperature between 3000 K and 10,000 K can be considered white. This range includes incandescent white (3000 K to 3500 K), daylight white (5000 K to 6500 K), and daylight white (6500 K to 10,000 K). In particular, a color temperature of 4000 K to 6000 K is preferred, with 4500 K to 5500 K being particularly preferred. Furthermore, light that is a well-balanced combination of RGB color components can be treated as white even if it is not completely equal in brightness. Because white light contains all wavelength components of visible light, diffraction occurs evenly, maximizing the plant transparency effect. White also makes it easy to achieve the highest brightness, effectively creating a glare effect. On the other hand, using monochromatic light (red, green, blue, etc.) can also produce a certain effect, but the pixelation effect tends to be less than with white light.

[0034] The brightness of the matrix display is 500 cd / m 2 Preferably, it is 700 cd / m or more. 2 or more than 1000 cd / m 2 Preferably, it is 1500 cd / m2 or more than 2000cd / m 2 It is particularly preferable that the brightness is 12000 cd / m or more. With such brightness, it is possible to generate a sufficient glare phenomenon, thereby making it possible to realize the pixelation phenomenon of the exhibit. However, if the brightness is too high, it may strain the eyesight of the viewer, so the brightness of the matrix display device should be, for example, 12000 cd / m 2 Preferably, it is 10,000 cd / m or less. 2 More preferably, it is 8000 cd / m 2 It is particularly preferred that:

[0035] Next, the configuration of an image displayed on the matrix display device will be described with reference to FIG. 3. As shown in FIG. 3, in this embodiment, the final image displayed on the matrix display device is generated by combining two layers: a graphic layer and a grid layer. The graphic layer can include any graphic image. The graphic image is, for example, an image containing artistic expression or decorative elements, and can include, for example, circular calligraphy, abstract patterns, natural landscapes, geometric patterns, characters, symbols, and various other shapes. As mentioned above, the area of ​​the graphic layer other than the graphic image (background image) is preferably white or a color similar to white. Furthermore, the graphic layer may be further divided into layers for the graphic image and the background image. In this case, the final image is generated by combining three layers: the background image layer, the graphic image layer, and the grid layer.

[0036] On the other hand, the grid layer includes a grid image for displaying some of the pixels constituting the matrix display device in black at a predetermined interval. The grid image is an element for realizing pixelation of the exhibit. In the present invention, the matrix display device is configured as a high-resolution display (for example, pixel spacing of 0.9 mm), but such a high resolution does not sufficiently achieve the pixelation effect of the exhibit. Therefore, by intentionally displaying pixels in black (non-emitting state) at a certain interval using the grid image, the effective pixel spacing is made coarse, thereby achieving the effect of matching the thickness of the lines in the exhibit.

[0037] The grid image pattern is basically configured as a regular grid pattern. Specifically, a grid pattern combining vertical and horizontal lines at a predetermined interval, a dot pattern, a stripe pattern, or the like can be used. The spacing between pixels displayed as black in the grid image can be adjusted according to the characteristics of the exhibit. For example, if the original pixel spacing is 0.9 mm, the effective pixel spacing can be made 1.8 mm by displaying every third pixel as black, or 2.7 mm by displaying every third pixel as black.

[0038] The display screen (particularly the graphic layer) of the matrix display device 10 is functionally divided into two areas, as shown in FIG. 3. The first area is the graphic drawing area. The graphic drawing area is an area where graphic images are displayed in high definition and where exhibits 30 do not overlap when viewed horizontally. The second area is the viewing area. The viewing area is an area where exhibits 30 at least partially overlap when viewed horizontally.

[0039] In the graphic drawing area, the application of a grid image is limited to ensure the visibility of the graphic image. Specifically, the mask area (grid invalidation) shown in Figure 3 invalidates (makes transparent) the black display of the grid image in the area that overlaps with the graphic image. This allows the original high resolution to be maintained in the graphic drawing area, allowing the graphic image to be displayed clearly. The mask area is an area that is dynamically generated according to the shape of the graphic image, and is set along the outline of the graphic image.

[0040] On the other hand, in the viewing area, a grid image is applied across the entire area. Since the main purpose of the viewing area is to realize pixelation of the exhibit 30, the grid image adjusts the effective pixel spacing. The background image displayed in the viewing area is usually a single color (white is preferable) or a relatively simple pattern, and is unlikely to create a visual sense of incongruity when combined with the grid image.

[0041] Furthermore, as shown in Figure 3, it is preferable to apply a grid image to the graphic drawing area as well, except for the masked portion (where the grid is disabled). This allows for visual consistency across the entire display screen. In the background portion of the graphic drawing area where no graphic image is displayed, a grid pattern is displayed using a grid image. It is preferable that the grid image in this background portion is configured with the same pattern and spacing as the grid image in the viewing area, allowing for consistency across the entire display screen.

[0042] By using these two areas appropriately, it is possible to maintain high-resolution graphic images in the graphic drawing area while achieving pixelation of the exhibit 30 in the viewing area. The pattern and spacing of the grid image can be varied in many ways depending on the type of exhibit 30 and the desired visual effect. These details will be explained next with reference to Figure 4.

[0043] 4 shows examples of various grid image patterns for realizing pixelation of the exhibit 30. These patterns are applied to the pixel array of the matrix display device 10, and adjust the effective pixel spacing by displaying some of the pixels in black (non-emitting state) at predetermined intervals.

[0044] Figure 4(a) shows the basic pixel configuration of a matrix display device 10. As shown in Figure 4(a), each pixel 12 has a light-emitting element 13 and is composed of red (R), green (G), and blue (B) color components. In this basic configuration, when all pixels 12 are in a light-emitting state (white display), the matrix display device 10 displays an image at the highest resolution.

[0045] Figure 4(b) shows a pattern in which an emitting pixel is placed every other pixel (every other pixel). In this pattern, one non-emitting pixel (black pixel) is placed between an emitting pixel and the next emitting pixel in both the row and column directions. For example, if the original pixel spacing is 0.9 mm, this pattern results in an effective pixel spacing of 1.8 mm. This pattern is suitable for achieving mild pixelation in relatively thin exhibits, for example.

[0046] Figure 4(c) shows a pattern in which an emitting pixel is placed every third pixel (every third pixel). In this pattern, three non-emitting pixels are placed between an emitting pixel and the next emitting pixel in both the row and column directions. For example, if the original pixel spacing is 0.9 mm, this pattern results in an effective pixel spacing of 3.6 mm. This pattern is suitable for achieving moderate pixelation for exhibits of medium thickness, for example.

[0047] Figure 4(d) shows a pattern in which an emitting pixel is placed every fifth pixel (every 5 pixels). In this pattern, five non-emitting pixels are placed between an emitting pixel and the next emitting pixel in both the row and column directions. For example, if the original pixel spacing is 0.9 mm, this pattern results in an effective pixel spacing of 5.4 mm. This pattern is suitable for achieving a strong pixelated effect on relatively thick exhibits.

[0048] Figure 4(e) shows a pattern in which four emissive pixels in two rows and two columns are grouped together, and these groups are arranged every other pixel (four pixels per group, every other pixel). In this pattern, one non-emissive pixel is placed between each group of four emissive pixels in both the row and column directions. This pattern allows for an appropriate spacing while ensuring the area of ​​the emissive portion. The spacing between the emissive pixel groups is three times the original pixel spacing. For example, if the original pixel spacing is 0.9 mm, the spacing between the emissive pixel groups will be 2.7 mm.

[0049] Figure 4(f) shows a pattern in which four light-emitting pixels in two rows and two columns are grouped together, and these groups are arranged every two pixels (one set of four pixels, every two pixels). In this pattern, two non-light-emitting pixels are placed between each group of four light-emitting pixels and the next group of light-emitting pixels in both the row and column directions. The spacing between the light-emitting pixel groups is four times the original pixel spacing. For example, if the original pixel spacing is 0.9 mm, the spacing between light-emitting pixel groups will be 3.6 mm. This pattern is effective for achieving a larger effective pixel spacing while maintaining the brightness of the light-emitting area.

[0050] These patterns can be selected according to the type, size, material, etc. of the exhibit 30. Specifically, the optimal pattern can be determined by considering the relationship between the thickness of the thinnest line portion of the exhibit 30 and the effective pixel spacing realized by the grid image. Generally, a noticeable pixelation effect can be achieved when the thickness of the line of the exhibit 30 is about the same as or slightly thinner than the effective pixel spacing.

[0051] Figures 5 to 9 are actual photographs showing the appearance of exhibits when each grid image pattern from Figure 4(b) to Figure 4(f) is actually applied. These photographs show examples using a matrix display device with a pixel pitch of 0.9 mm and rush grass as an exhibit. Each photograph was taken with a different grid image pattern applied, allowing visual confirmation of the change in the pixelated effect of the exhibit due to the different grid image patterns.

[0052] Figure 5 shows the appearance of the exhibit when the 1-pixel-altered pattern shown in Figure 4(b) is applied. Under this condition, the effective pixel spacing is 1.8 mm, and a slight pixelation effect is observed in the thin stems and leaves of the rush grass. Figure 6 shows the appearance of the exhibit when the 3-pixel-altered pattern shown in Figure 4(c) is applied. Under this condition, the effective pixel spacing is 3.6 mm, and a more pronounced pixelation effect is observed. Figure 7 shows the appearance of the exhibit when the 5-pixel-altered pattern shown in Figure 4(d) is applied. Under this condition, the effective pixel spacing is 5.4 mm, and the transparency effect of the rush grass stems and leaves is clearly visible. Figures 8 and 9 show the appearance of the exhibit when the patterns shown in Figures 4(e) and 4(f), respectively, are applied. These photographs demonstrate that the pixelation effect is achieved while maintaining the brightness of the luminous areas by using a pattern consisting of four luminous pixels.

[0053] These examples demonstrate that various degrees of pixelation can be achieved by combining the grid image pattern with the type of exhibit. In particular, for plants with many thin stems, such as rush grass, a visually striking pixelation effect can be achieved when the effective pixel spacing is in the range of 2mm to 5mm. Furthermore, these photographs demonstrate that the effect of the present invention is not simply an optical illusion, but an optical phenomenon that can be objectively recorded even when photographed with a camera.

[0054] Next, an exhibition system 100 according to a second embodiment of the present invention will be described with reference to Fig. 10. The second embodiment has the same basic components and operating principles as the first embodiment, but differs in the arrangement of the matrix display device 10 and the base 20. As shown in Fig. 10, in the second embodiment, the matrix display device 10 has a horizontally elongated shape. The matrix display device 10 is configured so that its horizontal length is greater than its vertical length. Such a horizontally elongated matrix display device 10 allows exhibits 30 to be displayed, for example, in an aisle or the like.

[0055] In the second embodiment, the pedestal 20 is attached to a wall. The pedestal 20, like the matrix display device 10, is fixed to the wall and installed at a predetermined height from the floor. The pedestal 20 can be attached to the wall using various attachment methods, such as brackets, metal fixtures, or wall-mounted structures. This wall-mounted configuration allows for effective use of floor space. In the second embodiment, as in the first embodiment, the height of the pedestal 20 is adjusted so that the exhibit 30 at least partially overlaps the display screen of the matrix display device 10 when viewed horizontally. The pedestal 20 is also positioned within 500 mm of the display screen of the matrix display device 10. These placement conditions allow for a pixelated effect similar to that of the first embodiment.

[0056] In this way, the exhibition system 100 of the present invention allows the arrangement of the matrix display device 10, base 20, and exhibit 30 to be changed in various ways, and can be flexibly applied depending on the installation environment and exhibition purpose.

[0057] In the above description of the present invention, the embodiments of the present invention have been described with reference to the drawings in order to express the contents of the present invention. However, the present invention is not limited to the above embodiments, and includes modifications and improvements that are obvious to those skilled in the art based on the matters described in the present specification.
