Description

  The present invention relates to an image display device and an illumination device configured by a plurality of light emitting elements.

  In a conventional full color image display device, generally, a plurality of light emitting elements of red, green, blue, and three colors are arranged to form one pixel, and an image is displayed by arranging a plurality of these pixels on the image display surface. It was. The accuracy of the image display surface is determined by the size of the pixel interval (pixel pitch), and the smaller the smaller the accuracy, the better the quality of the image display.

  As an example of such an image display device, an “image display unit and image display device” described in Patent Document 1 has been reported.

  In addition, as lighting devices, those using multicolor light emitting elements and those using white light emitting elements have been developed.

As an example of such an illumination device, a “surface illumination device and a liquid crystal display device” described in Patent Document 2 has been reported.

  In such an image display device, it is possible to display a high-quality image with high accuracy by reducing the pixel pitch, but the product price is high due to an increase in the number of light-emitting elements to be used. . On the other hand, when the pixel pitch is increased, the feeling of dots on the image display surface (the feeling of displaying an image instead of a surface) increases, and a high-quality image display becomes impossible and the number of light emitting elements is reduced. There has been a problem that a decrease in luminance is inevitable.

  In general, image display devices proceed to the manufacturing process of the image display part after the specifications (especially pitch) are determined. However, since the period from ordering to delivery of the image display device is short, it is impossible to cope with the manufacturing process. There was a risk of becoming. In addition, there were many cases in which the manufacturing process was unreasonable even after receiving an order. It is impossible to change the pixel pitch in the manufacturing process of the image display part. Therefore, it is not possible to proceed to the manufacturing process before the pixel pitch is determined, and there is a problem that the period from order receipt to delivery becomes longer. . Of course, it was impossible to change the pixel pitch after delivery.

  On the other hand, when displaying a three-dimensional image, for example, a curved surface, a curved surface is formed in a discontinuous manner by connecting a small flat display board, so that a smooth curved image cannot be displayed.

  Moreover, in such an illuminating device, generally, the shape of the light emitter and the light emission area could not be changed. For example, although the light emitting area can be increased by increasing the number of light emitters, there is a problem that it takes time and labor for wiring processing and the like. On the other hand, it is also difficult to manufacture a light emitter having an arbitrary shape. For example, when considering lighting in a room, a light emitter corresponding to the shape of the ceiling is manufactured, for example, when a light source is provided on the entire ceiling surface. It is very difficult. Even if it could be installed, it was impossible to change the light emitting shape and light emitting area of the light emitter by installing or moving furniture after the lighting device was installed.

  The first object of the present invention is to provide an image display device that can suppress the product price even if the pixel pitch is reduced, that is, can suppress the increase in the number of light emitting elements even if the number of pixels on the image display surface is increased. Another object of the present invention is to provide an image display device that can display a high-quality image with little reduction in luminance even when the pixel pitch is increased.

  The second object of the present invention is to proceed to the manufacturing process of the image display part before determining the pixel pitch, and can respond to the change of the pixel pitch both in the manufacturing process and after the delivery, corresponding to the short delivery time. An object of the present invention is to provide an image display device that can be used.

  A third object of the present invention is to provide an image display device capable of displaying a smooth curved surface image.

  In this illuminating device, an object of the present invention is to provide an illuminating device in which the shape and light emitting area of the light emitter can be freely set, and the shape and light emitting area of the light emitter can be freely changed even after the lighting device is installed. is there.

  In order to solve the above-mentioned problem, the invention according to claim 1 is an image display device having a pixel composed of a plurality of light emitting elements, and holding means for holding the plurality of light emitting elements movably in units of the light emitting elements. And mounting means for movably mounting the holding means, and the gist of the invention is that some or all of the plurality of light emitting elements are movable in units of light emitting elements.

  In order to solve the above problem, the invention according to claim 11 is a lighting device constituted by a plurality of light emitting elements, and a holding means for holding the plurality of light emitting elements movably in units of the light emitting elements, It has a mounting means for mounting the holding means so as to be movable, and the gist of the invention is that some or all of the plurality of light emitting elements are movable in units of light emitting elements.

  According to the image display device of the first aspect of the present invention, the image display apparatus has holding means for holding the plurality of light emitting elements so as to be movable in units of the light emitting elements, and has mounting means for mounting the holding means in a movable manner Since some or all of the plurality of light emitting elements can be moved in units of light emitting elements, the pitch, arrangement, arrangement method, and the like of the light emitting elements and the light emitting elements are used for the purpose of use of the image display device. It can be set freely and can be changed after setting.

  According to the illumination device of the eleventh aspect of the present invention, there is provided holding means for holding the plurality of light emitting elements movably in units of the light emitting elements, and having mounting means for detachably attaching the holding means. In addition, since some or all of the light emitting elements can be moved in units of light emitting elements, the pitch, arrangement, arrangement method, and the like of the light emitting elements and the light emitting elements are used for the purpose of use of the lighting device. It can be set freely and can be changed after setting.

  The best mode for carrying out an image display device and a lighting device according to the present invention will be described below with reference to the drawings. Although mainly described as an image display device, of course, it can also be applied to a lighting device.

  One feature of the present invention is that the number of pixels is increased by arranging and arranging light emitting elements instead of pixels so that they can move beyond the pixels.

  An example of this will be described with reference to FIGS.

  FIG. 1 shows an arrangement and an arrangement example (part) of the light emitting elements 1, and the light emitting elements 1 are mounted on the linear members 3 with an interval (pitch) b. The linear members 3 are arranged in order from the top with red, green, and blue at a constant interval (pitch) a. The red light-emitting element 1-1 attached to the linear member 3-1 is configured to be movable in the longitudinal direction along the linear member 3-1, and the green light-emitting element 1-2 is similarly line-shaped. The blue light-emitting element 1-3 can be moved in the longitudinal direction along the linear member 3-3, and the pitch b can be easily changed. is there. Further, the linear member 3 can also move in a direction perpendicular to the moving direction of the light emitting element 1 (in FIG. 1), and the pitch a formed by each linear member 3 can also be changed. Details of the movement of the light emitting element 1 and the change of the pitch b of the light emitting element 1 and the pitch a formed by the linear members 3 will be described later.

  In FIG. 1, red, green, and blue light emitting elements 1-1, 1-2, and 1-3 are vertically arranged to form two pixels 5-1. Here, when only the green light emitting element 1-2 (linear member 3-2) is moved in the direction of the arrow, as shown in FIG. 2, five pixels 5-2 can be formed. In this case, only the green light emitting element 1-2 shown in FIG. 1 has moved to the right by half the pitch b of the same color light emitting elements, but conversely, the red light emitting element 1-1 and the blue light emitting element 1- Even if the linear members 3-1 and 3-3 to which 3 is attached are moved to the left by half of the pitch b, the same effect can be obtained. That is, if the light emitting element is moved by a half of the pitch b of the light emitting element relative to the adjacent light emitting element, the number of pixels is greatly increased. Can be increased.

  Here, when the pitch a of the color and the color (the linear member 3) and the pitch b of the light emitting elements 1 arranged linearly are set to 1: 2√3, the light emitting element 1 is hexagonal. It is possible to form a higher quality image with less dot feeling arranged in a fine grid. This configuration is possible because the light emitting element 1 can move freely in units. However, it goes without saying that it is the purchaser or the user that determines the details of the pitch, arrangement, movement, and the like.

  In FIG. 1 and FIG. 2, the linear member 3 is arranged in a horizontal line, and the linear member 3 is moved sideways (the light emitting element 1 may be moved without moving the linear member 3). However, the linear member 3 may be moved vertically by rotating ± 90 degrees on a plane parallel to the paper surface. However, the same effect can be obtained by moving the same amount of rotation.

  FIG. 1 and FIG. 2 show the original image display portion. In actuality, a plurality of light emitting elements 1 are arranged many times as many as those in this figure. In FIG. 1 and FIG. 2, only three lines, red, green, and blue, are illustrated from the top, but in actuality, blue above red, green above it, and then red, and below blue Are arranged in the order of red, green below and further blue, and all the light emitting elements 1 in the image display section move relative to the light emitting elements 1 adjacent to each other over the frame of the pixels, One light emitting element can form six pixels, and the number of pixels can be dramatically increased.

  Up to this point, an example of the movement has been shown using FIG. 1 and FIG. 2. In this example, the light emitting elements 1 are arranged in a line and the arranged light emitting element groups are moved together. The element 1 can be moved alone.

  To raise the problem of this configuration, when the light emitting elements 1 of the same color shown in FIGS. 1 and 2 are arranged horizontally, lines of respective colors may appear when the image display unit is viewed from the horizontal direction. In order to solve this problem, specific examples 1 to 4 are shown below.

(Specific example 1)
As shown in FIG. 3, protrusions 7-1 are provided between the pitches of the same color in the linear member 3-4. In this case, since the light of the light emitting element 1 may be difficult to see in the lateral direction depending on the height of the projecting portion 7-1, the height of the projecting portion 7-1 is considered in consideration of the viewing angle in the lateral direction. Need to be adjusted.

(Specific example 2)
The light emitting elements 1 of the same color are alternately turned on or off, such as every other two. In this method, it is necessary to consider a decrease in luminance.

(Specific example 3)
As shown in FIG. 4, there is a method in which the respective light emitting elements 1 are not arranged in the same line by arranging them in a convex shape in the longitudinal direction. In the example shown in FIG. 4, the light emitting element 1 is mounted on the plurality of protrusions 7-2 provided on the linear member 3-5. Similarly to the above-described method (specific example 1), it is necessary to adjust the height of the protrusion 7-2 in consideration of the horizontal viewing angle.

(Specific example 4)
A part that is not on the same plane, for example, another image display plane slightly behind the image display plane, and when viewed from the front, such as plane P and plane Q shown in FIG. -1 is a green light emitting element 1-4, a green light emitting element 1-2 is blue light emitting element 1-5, and a blue light emitting element 1-3 is red light emitting element 1-6. Make sure they are arranged. In FIG. 5, the light emitting elements 1-1, 1-2, and 1-3 on the surface P are indicated by ○, and the light-emitting elements 1-4, 1-5, and 1-6 on the surface Q are indicated by x Showed. The configuration of the surface P and the surface Q can be easily configured by using the linear member 3-5 having the protrusion 7-2 shown in FIG. For example, the red light-emitting element 1-1 is attached to the protrusion 7-2 of the linear member 3-5, and the green light-emitting element 1-4 is interposed between the protrusions 7-2 (the portion that is not the protrusion 7-2). Attach to.

  In this case, as shown in FIG. 6, it is understood that the distance d between the two image display surfaces P and Q is preferably not large in consideration of the viewing angle θ. In this example, the two image display surfaces having the same arrangement of the light emitting elements 1 are slightly shifted from each other, but it is not necessary to have the same arrangement.

  For example, as shown in the front view of FIG. 7, green light-emitting elements 1-4 and blue light-emitting elements 1-7 are alternately arranged between red linear light-emitting elements 1-1, so that the green linear light-emitting elements are arranged. The blue light emitting element 1-5 and the red light emitting element 1-8 are alternately arranged between 1-2, and further, the red light emitting element 1-6 and the green light emitting element are disposed between the blue linear light emitting elements 1-3. Elements 1-9 are arranged alternately. In FIG. 7, the solid circles are the light emitting elements 1-1, 1-2, and 1-3 on the image display surface P on the near side, and the dotted circles are on the image display surface Q on the back side. Light-emitting elements 1-4, 1-5, 1-6, 1-7, 1-8, and 1-9. With such a configuration, there is an effect that the pixels 5-3 can be formed in a line shape of each color when viewed from the front.

  This problem can be solved by the above method. In addition, in general, the viewing angle is often larger in the left-right direction than in the up-down direction, and considering this, it seems that the effect of arranging the same color line vertically rather than horizontally is less affected.

  Further, although the number of pixels is greatly increased, it is expected that the luminance decreases as the number of light emitting elements is reduced. As one method for solving this, it is conceivable to provide a reflective surface in a portion where the light from the light emitting element is irradiated at a viewing angle other than the viewing angle and reflect the light within the viewing angle. This will be described in detail below.

  The reflecting surface reflects light from the light emitting element, and it is desired to configure light from other sources, for example, sunlight, to converge as much as possible. A flat reflecting surface such as a general mirror cannot converge light from the outside. An example is shown in FIGS.

  FIGS. 8A and 8B are views of the image display surface as viewed from the front, and FIG. 8A illustrates the minimum interval (pitch) between the light emitting elements 1 (the reflective surfaces 9-1 are adjacent to each other). Status). FIG. 8B shows a state in which the interval (pitch) of the light emitting elements 1 in FIG. 8A is changed (expanded).

  FIG. 9 is a cross-sectional view taken along the line AA shown in FIG. The reflecting surface 9-1 is a rotating paraboloid formed by rotating a parabola around the axis, and is installed on the back side of the light emitting element 1, and the light emitting element 1 is disposed at the focal point of the rotating paraboloid. As shown by the line in FIG. 9, the characteristics of the rotating paraboloid are parallel rays when the light from the focal point is reflected by the rotating paraboloid, and converging to the focal point when the parallel rays are reflected. . If the characteristics of this paraboloid are utilized, the light from the light emitting element 1 is reflected by the reflecting surface 9-1 and can be reflected almost to the front surface (within the viewing angle), while the reflected light from the other is suppressed.

The relationship between the parabola and the focal point that forms this rotating paraboloid (reflecting surface 9-1) is as follows. In FIG. 9, the vertical axis is y, the horizontal axis is x, and the focal length is F. A configuration in which y = [1 / (4F)] x ² is the most efficient, and light from the light-emitting element 1 is reflected parallel to the front.

  When the focal length F is increased, the parabola is expanded, and when the focal length F is decreased, the parabola is decreased. Increasing the focal length F improves the heat dissipation efficiency of the light emitting element 1. Further, by reducing the focal length F and bringing the light emitting element 1 closer to the reflecting surface 9, the tip E of the reflecting surface 9-2 is on the front surface (upper side in FIG. 10) than the light emitting element 1 as shown in FIG. 10. If it exists, the light emitting element 1 can be protected.

  Further, the focal length F can be set for each color depending on the characteristics of the emission color. That is, the focal length F can be set in consideration of the environment in which the image display apparatus is installed, the use conditions, the characteristics of the emission color, and the like, and the distance from the rotary paraboloid (reflection surface 9) after the light emitting element 1 is arranged. You may make it the structure which can change and adjust.

  By providing the reflecting surface 9 on the light emitting element 1 as described above, the luminance in the normal direction (front surface) of the image display surface is increased. However, if it is necessary to slightly diffuse in consideration of the viewing angle or the like, the light emitting element 1 May be arranged slightly close to the reflecting surface 9 or mounted so that the light emitting element 1 can be moved by a small amount.

  In the configuration in which the reflecting surface 9 is provided, in consideration of the effective area of the reflecting surface 9 and the size of the light-emitting element 1 itself, a larger one having a smaller pitch is more effective.

  Here, the linear member 3 to which the light emitting element 1 is attached will be described. Also in FIG. 8, it can be set as the structure substantially the same as above-mentioned FIG. 1 and FIG. The light emitting element 1-11 attached to the linear member 3-11 is configured to be movable along the linear member 3-11. Similarly, the light emitting element 1-12 is also moved along the linear member 3-12. The light emitting element 1-13 is also movable along the linear member 3-13. The difference from the example shown in FIG. 1 and FIG. 2 described above is that the light emitting elements 1 of the same color are not arranged on the linear members 3, and all the linear members 3 (3-11, 3-12, 3-13) In addition, three colors of red, green and blue are arranged in order. In other words, the light emitting elements 1-11 mounted on the linear members 3-11 are not the same color, but are arranged so that pixels of red, green, and blue can be formed in order. Similarly, the light-emitting element 1-12 attached to the linear member 3-12 and the light-emitting element 1-13 attached to the linear member 3-13 are not the same color but red, green, and blue 3 The colors are arranged so that the pixels can be formed in order. In the configuration shown in FIG. 8, it is easier to form pixels when the three-color light emitting elements 1-11, 1-12, and 1-13 are arranged on the linear members 3-11, 3-12, and 3-13. Details of this arrangement will be described later. FIG. 8A shows a state in which the distance (pitch) between the light emitting element 1 and the linear member 3 is minimized, and when it is minimized, the reflection surface 9-1 is formed on the entire image display surface. is doing. FIG. 8B shows a state in which the interval (pitch) between the light emitting elements 1 is increased along the linear member 3 and the interval between the linear members 3 is increased in a balanced manner in consideration of the interval between the light emitting elements 1. In such a state where the interval is widened, the efficiency of the reflecting surface 9-1 is deteriorated. In order to make the reflecting surface 9-1 efficient, it is necessary to set a pitch when used in advance to some extent, and the reflecting surface 9 may be provided in accordance with the pitch. Of course, when there is no change in pitch after installation, the entire image display surface can be a reflection surface as shown in FIG.

  11, 12 and 13 show other examples of front views of the image display surface having the reflection surface 9 shown in FIG. Although the reflecting surface 9 is a paraboloid of revolution, the front view is not a hexagon but a circle. FIG. 11 shows a state where the reflecting surfaces 9-3 of the adjacent light emitting elements 1 are adjacent to each other. FIG. 12 shows a state in which the light emitting elements 1 of a single color are arranged on the linear member 3-14, and the interval between the light emitting elements 1 is widened. FIG. 13 illustrates a state in which the light emitting elements 1 of three colors of red, green, and blue are arranged in order on the linear member 3-15, and the interval between the light emitting elements 1 is widened.

  Although not shown in the figure, the area of the reflecting surface can be changed by the light emitting element 1, and for example, the effect that the intensity of each color can be adjusted can be obtained. In any case, in the configuration in which the image display surface is formed in units of conventional pixels, it is difficult to efficiently provide the reflecting surface. In particular, in the configuration in which the paraboloidal surface is used as the reflecting surface, a plurality of light emitting elements 1 are provided at the focal point. It is impossible to arrange them, and it is possible to efficiently provide a reflective surface only when the light emitting element 1 is arranged and arranged in units.

  Provided that the light emitting element 1 is arranged and arranged in units, a rotating paraboloid as a reflecting surface is provided not only for an image display device but also for character display, traffic signal display on a road, and the like. I can. Furthermore, it is highly useful as a lighting device. For example, when a lighting device is required in a narrow limited space, it is more effective than conventional fluorescent lamps, saving space, reducing power, reducing weight, and extending life. It is effective for transportation equipment such as automobiles, and is particularly suitable for lighting equipment used in airplane cockpits.

  Here, touching on the manufacture of the rotating parabolic reflecting surface, it can be easily manufactured by forming the shape of the rotating parabolic surface by resin molding or the like and depositing metal on the rotating parabolic surface. Of course, it is not limited to this method.

  With this configuration, there is no problem as a lighting device, but there are some problems when used as an image display device. This problem will be described below.

  When displaying black as an image display, the light emitting element 1 does not emit light (turns off) at all. However, since the image display surface on which the light emitting element 1 is mounted is generally black, black is displayed. become. Here, when a reflection surface manufactured by metal vapor deposition or the like is adopted for this image display surface, not all the light from the outside can be converged, so the reflected light from the reflection surface is slightly anxious. For example, a material using a photocatalyst that reacts with light is attached to the reflecting surface. When the light emitting element 1 does not emit light, the light is black (absorbs light), and when it emits light, the light can be reflected. Such a configuration can eliminate the problem of reflected light. Of course, there is no problem for use in dark places because there is no reflected light. In addition, an image display device with low accuracy (a large pixel pitch) may be hardly affected by reflected light.

  In the configuration where the light emitting element 1 is mounted on the image display surface as described above, for example, when the green color is weaker than other colors, the size of only the green light emitting element is increased. It can also be done easily. This is because the light emitting elements adjacent to each other do not interfere with each other, and in the conventional arrangement in which pixels are arranged, when the green light emitting element is enlarged, the red and blue light emitting elements interfere with each other depending on the angle and cannot be seen. There was a possibility.

  When manufacturing an image display apparatus configured to be mounted on the image display surface in units of light emitting elements 1 as described above, a pixel base (pixel) for forming one pixel that has been manufactured and used conventionally. (In order to distinguish it from the “pixel stand”), it is difficult to use. Therefore, a method for arranging and arranging light emitting elements in units using an image display surface having a pixel table will be described below.

  In FIG. 14, the number of light emitting elements 1 arranged on the pixel bases 11-1 and 11-2 differs depending on the pixel base 11, and the pixel base 11-1 having five light emitting elements 1 and four light emitting elements are arranged. The part of the image display surface comprised with the pixel stand 11-2 is shown. In order from the top of the figure, the rows of the pixel bases 11-2 of the four light emitting elements 1 (referred to as rows because they are arranged horizontally) and the rows of the pixel bases 11-1 of the five light emitting elements 1 are alternately arranged. Has been placed. When an image display surface using the pixel base 11 is manufactured, it is easier to manufacture one row of pixel bases 11 having the same arrangement than to make pixel bases 11 having different arrangements. Here, when the center row is moved by one frame (one pixel unit) in the direction of the arrow, as shown in FIG. 15, the pixel unit 11-2 composed of four light emitting elements 1 and the pixel unit composed of five light emitting elements 1. 11-1 is arranged in a checkered pattern. At this time, the light-emitting elements 1 are arranged in a substantially hexagonal lattice pattern, and one light-emitting element 1 can form six pixels beyond the pixel table 11. This will be described by paying attention to the light emitting element 1-15 shown in FIG. The hexagonal shape is indicated by a dotted line with the light emitting element 1-15 as the center. As shown by the dotted line with one side of the hexagonal shape as the base and the light emitting element 1-15 as the apex, there are six triangles. Can be formed. Each of the three light emitting elements 1 forming the triangle has three colors of red, green, and blue, and six pixels 5-4 (only one example is shown in FIG. 15) can be formed. In FIG. 14, if one pixel base 11 is one pixel, the pixel base 11 is arranged in three columns and four rows, resulting in 12 pixels. The light-emitting elements 1 shown in FIGS. 14 and 15 have the same quantity, but in FIG. 15, the number of pixels similar to the pixel 5-4 is 80 pixels, and the number of pixels is dramatically increased.

  As shown in FIGS. 14 and 15, when the row pitch of the light emitting elements 1 is a and the column pitch is b, a: b = 1: √3, and the vertical and horizontal lengths of the pixel base 11 are set. A and B are also configured such that A: B = 1: √3 and a: A = 1: 3 (that is, a: b: A: B = 1: √3: 3: 3√3). Then, since the arrangement of the light-emitting elements 1 in the pixel table 11-1 and the arrangement of the light-emitting elements 1 in the pixel table 11-2 are the same in all the pixel tables, the light-emitting elements 1 are arranged in a hexagonal close-packed lattice. Will be. As in the example shown in FIGS. 1 and 2, the number of pixels increases as the light emitting element 1 moves, and a higher quality image formation with less dot feeling can be achieved. Further, as shown in FIGS. 8 to 13, a reflection surface can be provided.

  14 and 15, the light emitting elements of the same color are arranged in the horizontal direction as in FIGS. 1 and 2. However, FIGS. 14 and 15 are rotated ± 90 degrees to change the vertical and horizontal directions. You can also. However, the same effect can be obtained by moving in the same way no matter how much it is rotated.

  FIG. 16 shows another example (part) using a conventional pixel base. FIG. 16 shows an example in which the size of the pixel base 11 is slightly different. It is composed of a pixel base 11-1 having five light emitting elements 1, a pixel base 11-2 having four light emitting elements 1, and a slightly small pixel base 11-3 having three light emitting elements 1. Yes.

  When the light emitting elements as described above are arranged in a substantially hexagonal close-packed lattice shape, the pixel pitch can be easily changed. An example of this is shown below.

  2 and FIG. 15, the red, green, and blue light emitting elements 1 are arranged in a line at a constant interval a from the top. When the rows of the light emitting elements 1 are turned on every other row (the same applies even when the lights are turned off), the rows of the light emitting elements 1 that are turned on are red, blue, and green from the top. Further, when every other row of light-emitting elements 1 of the same color is lit, only the light-emitting elements indicated by the circles in FIG. 17 are lit, and a pixel that is slightly larger than the pixels in the case where all are lit can be formed. . By lighting up in this way, images with different pitches can be easily displayed. For example, the pitch can be changed between a bright place (such as outdoors in the daytime) and a dark place (such as at night), and the light emitting element 1 to be lit is ¼, so the running cost can be reduced. Furthermore, it is also possible to display images with different pitches on any part of the image display surface. For example, even when a partially high-definition image display is required, it can be handled.

  The problem with this configuration is that the lighting time varies depending on the light emitting element, which also affects the life of the light emitting element, and can be adjusted so that the lighting time does not vary as much as possible.

  As the method, as shown in FIG. 18, a quarter of light emitting elements to be used are divided into four groups (circle 1, circle 2, circle 3, circle 4), and this group can be easily changed. do it. The numbers in the circles shown in FIG. 18 indicate the sets. Further, the lighting times can be adjusted by accumulating and storing the four sets of lighting times and selecting the group to be used from (Circle 1, Circle 2, Circle 3, Circle 4). In the drawing shown in FIG. 18, the group indicated by circle 1 has the same arrangement as that of the light emitting element group lit in FIG.

  Here, one row is lit on two of the light emitting element rows, but if one row is lit on four rows and one of the light emitting element rows of the same color is lit on, four larger pixels can be formed. The number of light emitting elements to be turned on is 1/16 and the running cost is further suppressed. What is necessary is just to divide and adjust lighting time to 16 groups.

  The production of the image display surface in the image display device will be described below. In general, an image display apparatus manufactures a unit on which a plurality of light emitting elements are mounted, and a plurality of the units are arranged to form a display surface. This one unit is manufactured so that the pitch of the light emitting elements is adjusted between adjacent units. Usually, the pitch is determined at the stage of manufacturing the unit, and it is very difficult to change the pitch in the manufacturing process. One of the objects of the present invention is to provide an image display device that can cope with a change in pitch even during the manufacturing process and after delivery, and a method for dealing with this pitch change will be described below.

  FIG. 19 is a diagram showing a portion of a linear member 3-20 as a holding unit in which the light emitting elements 1 of the same color are arranged in a line. The light emitting element 1 is held by the support member 13 and attached to the linear member 3-20. The support member 13 (light emitting element 1) is mounted so as to be movable (slidable) in the longitudinal direction in the linear member 3-20. This movement is preferably continuous rather than discontinuous because fine adjustment is possible. The left figure shows a state where the pitch P (a) is small, and the right figure shows a state where the pitch P (a) 'is widened. Although it is necessary to consider a slightly longer wiring or the like, the pitch can be easily changed in the vertical direction on the drawing.

  At the time of changing the pitch, the interval (pitch) between the adjacent light emitting elements 1 can be easily changed by providing a scale on the linear member 3-20. In addition, there is a method for making the arrangement easy by making a jig or the like so that it can be easily arranged at equal intervals.

  Examples of the mechanism of the linear member 3-20 and the support member 13 are shown in FIGS. 20-1 (a) to (j) and FIGS. 20-2 (k) to (u) showing the AA cross section of FIG. Explained.

  In FIG. 20A, the linear member 3-20a is composed of two members, and the two members hold the both sides of the support member 13-a. The holding force of the support member 13-a is shown in FIG. Although it is strong, when attaching the support member 13-a to the linear member 3-20a, it is necessary to attach it from the end of the linear member 3-20a or to expand the two members. Take it. A wiring hole 15-a of the light emitting element 1 is provided in the support member 13-a. This wiring hole 15-a is the same in FIGS. 20-1 (b) to (j) and FIGS. 20-2 (k) to (q) shown below, but a conductor is attached to the linear member 3-20a. By simplifying the wiring of the light emitting element 1, it can be omitted.

  FIG. 20B is a type in which the support member 13-b is smoothly moved by the bearing 17-b.

  FIG. 20-1 (c) is a modified example of FIG. 20-1 (b) and is a type in which a plurality of bearings 17-c are provided.

  FIG. 20-1 (d) is a type in which the support member 13-d is attached to one linear member 3-20d, and the holding force is inferior to the type of holding from both sides, but the support member 13-d is attached. Even when the linear member 3-20d is attached to the image display surface, good operability cannot be denied. The support member holding portion 19-d of the linear member 3-20d has a smooth curve (circular shape) in cross section. This is designed so that the mounted support member 13-d does not come off, and may have any shape that does not come off even if it is not circular. However, since there is a possibility that a crack or the like may occur in the support member 13 due to the slide if the support member holding portion 19 has a sharp protruding portion, it is necessary to consider.

  FIG. 20-1 (e) is a modified example of FIG. 20-1 (d), which is a type in which the shape of the linear member 3-20e is changed.

  FIG. 20-1 (f) is a type in which the support member 13-f is moved smoothly by the bearing 17-f.

  FIG. 20-1 (g) is a modified example of FIG. 20-1 (f) and is a type in which a plurality of bearings 17-g are provided.

  FIG. 20-1 (h) shows a modification of the shape of the linear member 3-20h. In this configuration, when the image display surface is viewed from the front, the linear member 3-20h is hidden and light is emitted accordingly. The pitch of the element 1 can be reduced.

  FIG. 20-1 (i) shows a modification of the shape of the linear member 3-20i.

  FIG. 20-1 (j) also shows a modification of the shape of the linear member 3-20j.

  20-2 (k) is a modified example of FIG. 20-1 (h), and is a type provided with a bearing 17-k.

  FIG. 20-2 (l) is also a modified example of FIG. 20-1 (i), and is a type provided with a bearing 17-l.

  FIG. 20-2 (m) is a modified example of FIG. 20-2 (k), and is a type in which a plurality of bearings 17-m are provided.

  FIG. 20-2 (n) shows a modification of the shape of the linear member 3-20n.

  FIG. 20-2 (o) also shows a modification of the shape of the linear member 3-20o.

  FIG. 20-2 (p) is a type in which the linear member 3-20p is a string, and this type also has a configuration in which the support member 13-p is mounted from the end of the linear member 3-20p.

  20-2 (q) is a modified example of FIG. 20-2 (p), and is a type in which the linear member mounting portion 18 is provided on the support member 13-q so that the linear member 3-20q can be easily mounted. . In this drawing, the linear member mounting portion 18 is provided with a straight cut, but it does not have to be linear. Rather, the linear member mounting portion 18 does not need to be linear, so that the support member 13-q is not detached from the linear member 3-20q. A curve cut may be used. By setting it as such a structure, if at least any one of support member 13-q and linear member 3-20q has moderate elasticity, it will become possible to mount from anywhere, not from the end.

  FIG. 20-2 (r) also shows a modification of the shape of the linear member 3-20r, but the wiring hole 15 is not described. This is a type in which a conductor is attached to the linear member 3-20r.

  FIG. 20-2 (s) is a modified example of FIG. 20-2 (r), and is a type in which the shapes of the linear member 3-20s and the support member 13-s are changed.

  FIG. 20-2 (t) is also a modification of FIG. 20-2 (r), and is a type in which the shapes of the linear member 3-20t and the support member 13-t are changed.

  FIG. 20-2 (u) is a modified example of FIG. 20-2 (s) and is a type provided with a bearing 17-u.

  When the support member 13 is manufactured from an elastic member, the mounting on the linear member 3 becomes extremely easy and can be mounted at any position of the linear member 3-20 (except for FIG. 20-2 (p)). ) For this mounting, for example, the linear member 3-20 may be an elastic member, and when the light emitting element 1 is mounted at an arbitrary position, the linear member 3-20 may be held by the elasticity (pressure) of the linear member 3-20.

  Further, although the amount of the light emitting elements 1 (support members 13) to be used varies to some extent due to the difference in the interval (pitch) between the light emitting elements 1, the support members 13 can be easily attached to and detached from the linear members 3-20. The configuration is such that an appropriate number of supporting members 13 (including the light-emitting elements 1) to be mounted are prepared in advance, so that a change in pitch can be dealt with.

  As a method of fixing the support member 13 to the linear member 3-20, there are examples shown in FIGS. 21A and 21B in addition to a method of fixing by the elastic pressure by a member having elasticity.

  In FIG. 21A, the support member 13-1a moves (slides) on the linear member 3-21a. However, the support member 13-1a is linear member by the fixing member 21-a attached to the support member 13-1a. It is fixed to 3-21a. The fixing member 21-a can move without touching the linear member 3-21a when the support member 13-1a moves. When the fixing member 21-a contacts the linear member 3-21a, it cannot move smoothly. In addition, the fixing member 21-a or the linear member 3-21 a is worn, and a problem such as being unable to fix the fixing member 21-a or the linear member 3-21 a occurs. The fixing member 21-a may be a screw-like member or an elastic member. Any member that can fix the supporting member 13-1a may be used.

  FIG. 21B shows an example in which the fixing member 21-b is mounted on the linear member 3-21b side. In this case, since it is necessary to provide a plurality of holes for attaching the fixing member 21-b, the type in which the fixing member 21-a is attached to the support member 13-1a in FIG. Although not shown in the drawings, for example, there is a method using a bayonet coupling that rotates and fixes a support member at a position where it is desired to fix. Moreover, like a string holder (a holder for holding a string often used in sportswear, a rucksack, etc.), it is possible to use a holder that is opened by being pinched with fingers and held when released. This is effective when the linear member 3 has a string shape. The movement and fixation of the string-like linear member 3 will be described later. As described above, there are many fixing (bonding) methods, but they may be selected according to the intended use. If it is often assumed that the pitch is changed, it is easier to deal with if it is easier to attach and detach, and if there is almost no change in the pitch, it may be firmly fixed.

  FIG. 22 shows a state (part) in which a plurality of linear members 3-22 having the same configuration as the linear member 3-20 shown in FIG. 19 are manufactured and arranged and mounted in units (image display devices). . The linear member 3-22a shown in FIG. 22 has a plurality of red light emitting elements 1 mounted thereon, the right adjacent linear member 3-22b has the green light emitting element 1 mounted thereon, and the right adjacent linear member 3-22a. The blue light emitting element 1 is attached to the member 3-22c, and then the red light emitting element 1 is attached to the linear member 3-22d on the right side in the same manner as the linear member 3-22a. Although not shown in FIG. 22, green and blue are continued on the right side. Here, the linear members 3-22 are arranged vertically, but it goes without saying that the same effect can be obtained by arranging them horizontally or diagonally. When arranged side by side, an effect as a louver (antireflection means such as sun rays, rain protection, etc.) can also be expected. The interval between the linear members 3-22 and the pitch P (b) can be freely set, and can be adjusted as long as the members do not overlap. Further, the unit (image display device) can be easily attached and detached, so that the movement of the light emitting element 1 shown in FIG. In FIG. 22, the light emitting elements 1 are arranged in a straight line horizontally. However, the pitch of the light emitting elements 1 can be changed as shown in FIG. In other words, an increase in the number of pixels can be expected depending on the arrangement method as in the configuration shown in FIGS.

  23A, 23B, and 23C show a type in which the linear member 3-23 has a string shape. The linear member 3-23 is thinned in a string shape (thread shape) so as to suppress interference of the member itself, and is similar to the type shown in FIGS. 20-2 (p) and (q). FIG. 23A, FIG. 23B, and FIG. 23C show modifications of the support members 13-3a, 13-3b, and 13-3c, and the support member 13-3, respectively. By making the linear member 3-23 into a string shape (thread shape), the shape can be easily changed and the degree of freedom can be improved, and the impact can be mitigated against an external impact. There is also an effect of making. In FIGS. 23A, 23B, and 23C, the light emitting element 1 (supporting member 13-3) is supported by only one linear member 3-23 (thread-like member). There is a possibility that the irradiation direction of the light emitting element 1 is shifted by rotating in the rotation direction around the member 3-23. In order to prevent this, although there is no description of the drawings, a plurality of linear members 3-23 such as two or three may be used instead of one. Moreover, the linear member 3 can also be made into a plate-shaped member, and the effect substantially the same as the structure which provides two or more thread-like members is acquired.

  Here, the movement and fixation of the light emitting element 1 (support member 13-3) in the case of the string-like (thread-like) linear member 3-23 will be described with reference to the examples shown in FIGS. .

  FIG. 24A shows a state in which the support member 13-4a is fixed to the string-like linear member 3-24a. When the fixing member 21-1a is pushed in the direction of the arrow, the fixing is released and the state is opened. A member having elasticity (hereinafter referred to as an elastic member 23-a) is mounted between the support member 13-4a and the fixing member 21-1a, whereby the flange of the hole 25-a of the support member 13-4a is fixed to the fixing member 21-1a. The linear member 3-24a is sandwiched and fixed by the flange of the hole 27-a of the member 21-1a. If the flanges of the holes 25-a and 27-a are members having a large friction, the fixing force is increased. Further, both the holes 25-a and 27-a are not uniform in width, but the width of the hole is narrowed at a fixed position, and the width of the hole is set wide at a position where the hole is opened. By adopting such a configuration, the movement can be performed smoothly and the fixing can be strengthened.

  FIG. 24B shows an example in which there are two linear members 3-24b. By providing the plurality of linear members 3-24b as described above, the illumination direction of the light emitting element 1 is stabilized. Although not shown in the drawing, the three linear members 3-24b can be easily formed in the same manner. The linear member 3-24b has a plurality of light emitting elements 1 mounted thereon, and considering the wiring, it is desired to mount the wiring on the linear member 3-24b. It is desired that the light-emitting element 1 can cope with movement in the linear member 3-24b, such as a rail such as a movable lighting fixture used for indoor lighting. In the configuration using the string-like linear member 3-24b shown here, an image display device such as a curtain or a warm bath can be provided.

  Here, a type in which three colors of red, green, and blue are attached to the linear member 3 will be described with reference to FIGS. 25 and 26. FIG.

  In FIGS. 25A and 25B, the types of linear members 3-25a and 3-25b are different, but red, green, and blue (R, G, B) are arranged in order from the top and mounted together. ing. This arrangement is one example, and may be arranged in order of red, blue, and green. The type in which the same color is arranged has an advantage that it is easy to manufacture. However, in the type in which the three colors shown in FIG. 25 are mounted, all the linear members 3-25 are arranged in the same arrangement (in this case, R, G from the top). , B). In the type in which the same color is mounted, pixels cannot be formed because the three colors are not aligned without the three linear members 3, but in this type, similar pixels can be formed with the two linear members 3-25. This is shown in FIG.

  FIG. 26 shows three linear members 3-26a, 3-26b, and 3-26c. However, red, green, and blue (R, G, and B) are detected by the two linear members 3-26a and 3-26b. ) Becomes a triangle to form the pixel 5-5. Here, considering the pixel by paying attention to the blue light emitting element 1-26, red, green, blue (R) linearly from the top with the light emitting element 1-26 in one linear member 3-26a. , G, B), and the pixel 5-6 is formed. Similarly, G, B, and R are formed from the top with the light emitting element 1-26 as the center to form the pixel 5-7, and further, B, R, and G are formed from the top with the light emitting element 1-26 on the pixel 5-8. Is forming. There are three pixels (5-6, 5-7, 5-8) including the light emitting element 1-26 in the linear member 3-26a. The linear pixels 5-9 and 5-10 can also be formed with the light emitting element 1 of the adjacent linear member 3-26b, and three pixels (5-6, 5-7, Similarly to the formation of 5-8), three pixels 5 can be formed in each linear shape. Thus, the light emitting element 1-26 forms nine linear pixels. Since the pixel including the light emitting element 1-26 forms the above-described triangular pixel 5-5, one light emitting element 1 forms 15 pixels depending on the concept.

  In the above-described type in which one linear member 3 is mounted with three colors of red, green, and blue, when the same arrangement and arrangement (pitch) of the light emitting elements 1 are considered, the distance between the linear members 3 is the same color. Can be wider than the type that wears. This can be easily understood by comparing the examples shown in FIGS. 12 and 13, but if the interval between the linear members 3 of the same color type (hereinafter referred to as a single color type) is set to 1, red, green and blue The spacing between the linear members 3 of the type with three colors (hereinafter referred to as the three-color type) is √3, and it can be seen that the three-color type is clearly advantageous. The reason is that the three-color type can make the pitch smaller. Further, when the same arrangement and arrangement (pitch) of the light emitting elements 1 are considered, the usage amount of the linear member 3 is smaller in the three-color type, and the cost is reduced. In addition, the weight can be reduced.

  Next, the movement and fixation of the linear member 3 will be described. 27A and 27B show a state where the linear member 3-27 is fixed. FIG. 27A is a diagram (part) of the image display surface viewed from the front, and FIG. 27B is a cross-sectional view taken along the line AA shown in FIG. A plurality of linear members 3-27 are held and fixed by a holding member 29 (in this case, a wire-like member) as mounting means for mounting and holding the linear member 3-27 and a fixing member 31. The configuration of the fixing member 31 and the linear member 3-27 is the same as the configuration of the string holder described above. When the fixing member 31 is pushed in the direction indicated by the arrow in FIG. The fixing of the holding member 29 by the hole 32 provided in the fixing member 31 and the hole 4 provided in the linear member 3-27 is released, and the linear member 3-27 extends along the wire-like holding member 29. It can move (slide). FIG. 27 (c) shows a different type of linear member 3-27. The fixing member 31-c is also different from the types shown in FIGS. 27 (a) and 27 (b). 27 (a) and 27 (b), a means for fixing the linear member 3-27 to the holding member 29 between the fixing member 31 and the linear member 3-27 is provided. In c), the linear member 3-27c is fixed to the holding member 29-c by the fixing member 31-c alone.

  Although only the upper part is shown in FIG. 27, a plurality of configurations of the holding member 29 and the fixing member 31 can be provided in the lower part and the intermediate part. By providing a plurality of locations in this manner, the holding force increases, and the irradiation direction of the light emitting element 1 is stabilized.

  When changing the interval (pitch) between the adjacent linear members 3-27, similarly to changing the interval (pitch) of the light emitting elements 1 in the linear member 3-20 shown in FIG. By providing a scale on the holding member 29, the interval (pitch) between the adjacent linear members 3-20 can be easily adjusted. Further, a dedicated jig or the like can be manufactured so that the linear members 3-27 are arranged at equal intervals, and the pitch of the linear members 3-27 can be easily changed. Of course, when changing the interval (pitch) of the light emitting elements 1 in the linear member 3-20, it can be manufactured together with the jig to be used.

  28 (a) and 28 (b) show modifications of the holding member 29. FIG. FIG. 28A is a diagram (part) of the image display surface as viewed from the front, and FIG. 28B is a cross-sectional view taken along line AA shown in FIG.

  The holding member 29-1 shown in FIG. 28 (a) shows a case where the holding member 29-1 is formed into a planar shape that forms an image display surface. The holding member 29-1 is provided with a protrusion 33. The protrusion 33 is sandwiched between the linear member 3-28 and the fixing member 31-1 by the elastic pressure of the elastic member 35-1, and obtains a holding force. Yes. This is also substantially the same structure as the above-mentioned string holder, and the elastic member 35-1 is compressed and released by pushing the fixing member 31-1 downward, and the linear member 3-28 moves along the protruding portion 33. (Slide) is possible. FIG. 28 also shows only the upper part, but means equivalent to the protrusions 33 and the like are provided in the lower part and the intermediate part, and the irradiation direction of the light emitting element 1 can be stabilized. The holding member 29-1 may be provided on the entire image display surface (entire surface), but may be provided not on the entire surface but only on a portion where the protrusion 33 is provided (partial).

  Furthermore, the modification of the holding member 29 and its related member is shown to Fig.29 (a)-(i). This is a cross-sectional view showing a coupled state of the linear member 3-29 and the holding member 29-2, similarly to the cross-sectional views shown in FIGS. 27 (b) and 28 (b).

  FIG. 29 (a) has a projection 33-1a similar to FIG. 28, and a linear member 3-29a is fitted into the projection 33-1a, and the linear member 3-29a on the image display surface is externally attached. The linear member 3-29a is mounted so as not to move unless a force from is applied.

  FIG. 29 (b) is a modification of FIG. 29 (a), and is a type in which a protrusion 33-1b is provided on a linear member 3-29a.

  FIG. 29 (c) shows a configuration in which a hook 37-c is provided on the linear member 3-29c and is hooked on the holding member 29-2c, which is also mounted so as not to move unless external force is applied to the linear member 3-29c. ing.

  FIG. 29 (d) is a modification of FIG. 29 (c), in which a bearing 39-d is provided between the holding member 29-2d and the hook 37-d, so that the linear member 3-29d moves smoothly. Is.

  FIG. 29 (e) is a modification of FIG. 29 (c), which is a type in which a fixing member 31-2e is provided in the portion of the hook 37-e, and the holding force becomes strong.

  29 (f) and 29 (g) are types in which a holding member 29-2f such as a curtain rail is provided and a slidable member is attached to the upper part of the linear member 3-29f.

  FIG. 29 (g) is a modification of FIG. 29 (f), and a bearing 39-g is added between the linear member 3-29g and the holding member 29-2g.

  FIG. 29 (h) is a type in which a ring-shaped hook 37-h is attached to a wire-shaped holding member 29-2h.

  FIG. 29 (i) is a modification of FIG. 29 (h), and is a type in which a hook 37-i is attached to a wire-like holding member 29-2i. If this type of hook 37-i is used, the linear member 3-29i can be easily attached to and detached from the holding member 29-2i.

  Although only the upper part is shown in FIGS. 29A to 29I shown here, a plurality of these holding members 29-2 can also be provided in the lower part and the intermediate part. With regard to the movement (slide) of the linear member 3-29 shown above, it is necessary to consider the wiring, etc., and the wiring (for example, the wiring itself can be lengthened corresponding to the movement (sliding) interval. Easy wiring, etc.)

  With the configuration shown here, the arrangement of the light-emitting elements 1 on the unit (image display device) can be freely arranged on the vertical and horizontal planes in the unit (image display device) both at the manufacturing stage and after delivery. The pitch of the element 1 can be changed and the pixel pitch can be changed.

  Up to this point, the movement of the linear member 3 has been described. The movement direction of the linear member 3 is on the image display surface to be formed, and moves in the direction perpendicular to the longitudinal direction of the linear member 3 ( Although a configuration for sliding) is shown, the present invention is not limited to this configuration.

  As shown in FIG. 30, the moving direction of the linear member 3-30 is not perpendicular to the longitudinal direction of the linear member 3-30 even on the same image display surface, but the holding member 29-3. And 45 degrees by changing the angle formed by the linear member 3-30. This angle of 45 degrees is an example. If the angle is further changed, it can be moved to 30 degrees, 60 degrees, and the like. Although there is no description of the drawings, for example, it is not parallel to the image display surface, and can also be moved at an angle of 30 degrees, 45 degrees, 60 degrees, and the like.

  Conventionally, when displaying an image of a curved surface, since a discontinuous curved surface is formed by connecting small flat display panels, a smooth curved surface cannot be obtained. If the linear member 3 described so far is used, it is possible to display a smooth curved image on a columnar display panel such as a column. This example is shown in FIGS. 31 (a) and 31 (b).

  FIG. 31A shows a state in which a plurality of linear members 3-31 having a plurality of light emitting elements 1 mounted thereon are arranged in a columnar shape around the column portion 40 to form an image display surface.

  FIG. 31 (b) is a partially enlarged view of a portion B shown in FIG. 31 (a). The linear member 3-31 is connected to an adjacent linear member 3-31 by an angle adjusting member 42 such as a hinge via a holding member 29-4 so that the angle can be freely adjusted. The angle adjusting member 42 may be integrated with the holding member 29-4.

  Here, an example in which the shape of the image display surface changes will be described with reference to a perspective view shown in FIG. As shown in FIG. 31B, the angle adjusting member 42 allows the linear member 3-31 to freely adjust the angle with the adjacent linear members 3-31. The state in which the image display surface is formed in a cylindrical shape around the column portion 40 can be changed to a state in which the flat image display surface shown in FIG. The deformation shown in FIG. 31 (c) is a planar image obtained by causing the holding member 29-4 to be gradually 180 degrees from the adjacent linear members 3-31 by an external force. A state in which the shape changes to the display surface is shown.

  Regarding the angle adjustment by the angle adjustment member 42, the angle that can be adjusted by a member such as wiring is limited to some extent, but the angle adjustment is possible in units of the linear members 3-31 adjacent to each other, and the image The number of linear members 3-31 on the entire display surface may be large, and even a small amount of angle adjustment results in a large shape change on the entire image display surface.

  Such deformation of the shape of the image display surface is possible even when the image is being displayed. As shown in FIG. 31 (c), the cylindrical image display surface is developed (in a flat shape). Can be repeated. The shape of the image display surface can be greatly changed, such as widening or closing, and a strong impact can be given to the viewer. If the configuration can be changed in such a state that an image is displayed, the commercial effect becomes very large.

  In order to cope with this deformation, it is necessary to consider the wiring, and the holding member 29-4 for holding the above-described linear member 3-31 is easy in addition to the type shown in FIG. It is an essential condition that the shape can be changed (for example, the wire-shaped member shown in FIGS. 29H and 29I).

  In FIG. 31, the image display surface covers the entire periphery of the column portion 40 and the entire image display surface can be changed in shape. However, the entire image display surface does not need to be covered, and the entire shape needs to be changed. Nor. It may be a partial shape deformation.

  Furthermore, as shown in FIG. 32, the linear member 3-32 can be a curved line instead of a straight line, and an effect that a three-dimensional smooth curved surface that can never be obtained by a flat display panel can be expressed. is there.

  33A, 33B, and 33C show examples in which the spherical surface is the image display surface. FIG. 33A is a perspective view showing a spherical image display surface. In this spherical image display device, linear members 3-33 are arranged along meridians from the axis of a sphere.

  FIG. 33 (b) is a cross-sectional view showing a state perpendicular to the axis of the sphere shown in FIG. 33 (a), that is, a state cut along a latitude line.

  FIG. 33C is a cross-sectional view showing a state cut along the meridian of the sphere shown in FIG.

  As this linear member 3-33, it is preferable to use one in which the three colors shown in FIGS. 25A, 25B and 26 are attached to one linear member 3. The reason is that the area where the linear member 3-33 is arranged is small around the axis (the uppermost part and the lowermost part), and the monochromatic linear member 3 does not have the three colors of red, green, and blue, so that pixels cannot be formed. This is because there is a possibility. In this sphere, if the pitch of the light emitting elements 1 is not changed, the light emitting elements can be arranged on the spherical surface from the manufacturing process.

  FIG. 34A shows an example in which the image display unit moves (changes the shape) in a state where an image is displayed as shown in FIG. In FIG. 34A, the linear member 3-34 has an amplitude in the front-rear direction. If the linear member 3-34 that continues to the next side repeats the amplitude in order, it becomes like a wave motion. Similarly, a strong impact can be given to the viewer, and the commercial effect is increased.

  FIGS. 34B and 34C show the shape changing means for the image display surface. A method of applying an external force to move as shown in FIG. 34 (a) will be described with reference to FIGS. 34 (b) and 34 (c). FIG. 34 (b) is a plan view of the shape changing means, and FIG. 34 (c) is a front view.

The shape control members 43 shown in FIG. 34 (b) are provided radially at intervals of 30 degrees. Since it is arranged at the same position as the position of the timepiece, the shape control member 43-1 at the position of (9) is at the uppermost position, which will be described with reference to the timepiece. This is shown in FIG. It can be easily understood by looking at FIG. Next, there is a shape control member 43-2 at the position (8), and then there is a shape control member 43-3 at the position (7). In this way, the shape control member 43 is provided at an equal phase difference, in this case, 30 degrees, and the shape control members 43 are mounted at equal intervals as shown in FIG. This interval is an interval between the linear members 3-34, and a plurality of shape control members 43 are provided so as to correspond to the respective linear members 3-34. In FIG. 34 (b), only 12 are visible due to the nature of a plan view, but as shown in FIG. 34 (c), a large number of shape control members 43 are provided. In FIG. 34 (c), the shape control member 43- Although up to 17, the number of the linear members 3-34 can be provided. In FIG. 34 shown here, the shape control member 43-1 and the shape control member 43-13, the shape control member 43-2 and the shape control member 43-14 have the same phase, and there are 12 types of phases. A waveform (sine curve) of one cycle is formed by the twelve linear members 3-34 controlled by the shape control members 43-1 to 43-12.

  FIG. 34 (d) is a side view of the image display surface in a state where the shape changing means is shown in FIG. 34 (c). The linear member 3-34 has a waveform (sine curve).

  FIG. 34 (e) shows an image display screen when the shape changing means shown in FIG. 34 (b) is rotated 30 degrees in the direction of the arrow, that is, with a phase difference of 30 degrees from FIG. The waveform of the linear member 3-34 is shifted by one frame from FIG. 34 (d). Further, by rotating, the movement of the waveform moves, and an image display that gives an impact to the viewer is possible. For smooth waveform movement, the phase difference may be reduced to 15 degrees, 5 degrees, or the like. When the phase difference is 15 degrees, there are 24 types of phases, and 24 linear members 3-34 form one sine curve for one cycle.

  Further, the amplitude can be changed by changing the length of the shape control member 43. On the other hand, although this configuration is considered mechanically, it can also be controlled electronically. This configuration is capable of impacting not only the image display but also the viewer as a lighting device, and has high utility value.

  When considering the method of using the linear member 3 described above, the linear member 3 can be attached to a shutter attached to an entrance of a building and the surface of the shutter can be used as an image display surface. Further, the linear members 3 can be arranged and arranged in a shutter shape. This is also an effect made possible by manufacturing the linear member 3. Also in this case, it is necessary to consider the wiring.

  35 (a) and 35 (b) show diagrams in which the linear member 3-35 is formed of an elastic member and the shape can be changed.

  FIG. 35A shows a state in which the linear member 3-35a is deformed (moves) on the surface of the image display surface.

  FIG. 35B shows a type in which the linear member 3-35b is deformed (moved) in the normal direction of the image display surface.

  Of course, both the configurations of FIGS. 35A and 35B can be adopted. In such a configuration, the shape can be changed while the image is displayed, and the effect can be alleviated even when some impact is applied to the image display surface.

  Next, in addition to the fixing method of the linear member 3 described above, a fixing method when the linear member 3 hardly moves after the linear member 3 is mounted on the unit (image display surface) will be described.

  FIG. 36 shows an example. Although the upper part, the middle part, and the lower part are shown, the number of the holding members 29-10 only needs to be such that the linear members 3-36 can be appropriately arranged. In FIG. 36, the fixing member 31-10 is fixed using screws, but other fixing methods such as riveting, clamping, fixing with a spring, fixing with an adhesive, a hook, and fixing with a string may be used. When the arrangement and arrangement of the light emitting elements 1 are assumed to be changed, it is preferable that the light emitting elements 1 be easily attached / detached. However, when the light emitting elements 1 are hardly moved after being set once, a strong fixing method may be used. If there is no wind or vibration, there is no problem because the arrangement of the light emitting element 1 does not shift even if the upper part is fixed.

  The method of configuring the image display surface with the linear members 3 as described above can be used not only for image display but also for illumination. There is an effect that the size and pitch of the illumination can be easily adjusted. Details thereof will be described later.

  Here, the manufacture of the image display device main body will be described. When using said linear member 3, roughly dividing, two types are assumed. The first type is shown in FIGS. 37 (a) and (b). FIG. 37 (a) is a diagram showing the entire image display device, and FIG. 37 (b) is an enlarged view of the portion shown in FIG. 37 (a). FIG. 37 shows a type in which the linear member 3-37 is directly attached to the image display unit, and it is necessary to manufacture a relatively long linear member 3-37. The long linear member 3 may be manufactured by joining the short linear members 3 together.

  An example of joining the linear members 3 is shown in FIGS. 38A shows a type in which the connecting means 41-1 is independent, and FIG. 38B shows a type in which the connecting means 41-2 and 41-3 are provided at both ends of the linear member 3-38b. Is shown. Both linear members 3-38 are connected via connecting means 41. Although FIG. 38A is independent, it may be configured to be attached or bonded to either one of the linear members 3-38a. This connection (fixing) method is the same as the method for fixing the linear member 3 shown in FIG. 36 to the unit (image display device), such as screws, rivets, clamps, spring fixing, adhesives, and hooks. Other fixing methods such as fixing with a string or string may be used.

  FIG. 38B shows only one example, and various shapes and connection methods can be used. FIG. 38B shows a configuration that can be connected by sliding perpendicular to the longitudinal direction of the linear member 3-38b. This sliding direction may be either a vertical direction or a parallel direction with respect to the image display surface. Moreover, it is good also as a structure which slides (for example, inserts) like a bayonet coupling, rotates, and connects. By combining the slide and rotation, such as bayonet coupling, the connection is hard to come off and becomes strong. In the configuration in which the connecting means 41 is provided as described above, the short linear members 3 are connected to each other so that the light emission can be performed when the interval (pitch) between the adjacent light emitting elements 1 is changed as compared with the long linear members 3. The length of the movement of the element 1 is shortened and the adjustment becomes easy.

  The second type is a type in which the image display unit is divided into several units as shown in FIGS. 39A and 39B, and a linear member 3-39 is attached to this unit. FIG. 39A is a diagram illustrating the entire image display device, and FIG. 39B is a diagram illustrating one unit that is a part of the image display device. In FIG. 39, 4 × 4 16 units are used, but any number can be handled in the same manner. In this type, it is necessary to adjust the color and position of the light emitting element because it is desired to form a pixel similar to the pixel in the unit between adjacent units (to make the unit compatible). .

  One example of this method is shown in FIG. 40 is an enlarged view of each of the corners (A, B, C, D) of the unit shown in FIG. 39 (b) (the enlarged view of the corner A is FIG. 40 (a), the enlarged view of the corner B). FIG. 40B corresponds to FIG. 40 (b), and shows a case where the linear member 3-40 having the single-color light emitting element 1 disposed thereon is attached. a), linear members 3-40 each having red, green and blue (R, G, B) light emitting elements 1 arranged from the left side of the unit shown in FIG. A blue linear member 3-40 is attached to the right end side as shown in FIGS. 40 (c) and 40 (d). If the number of the linear members 3-40 attached to one unit is a multiple of 6, pixels are easily formed between adjacent units. Moreover, also about adjustment of the space | interval of the linear member 3-40, it comprises so that the space | interval of the linear member 3-40 with an adjacent unit may become equal to the space | interval of the linear member 3-40 in a unit. Similarly, the adjustment in the vertical direction needs to be adjusted so that pixels similar to the pixels in the unit can be formed between the units connected vertically. In the example shown in FIG. 40, pixels similar to those in the unit can be formed between the units connected vertically and horizontally. It is desirable that the linear member 3-40 has a length from the upper end to the lower end of the unit so as to cope with a change in pitch (in the case of the unit shown in FIG. 40). The problem with this configuration is that when changing or adjusting the pitch, the number of the linear members 3-40 may not be a multiple of 6, depending on the pitch. There is an arrangement of the light emitting elements shown in FIG.

  FIG. 41 shows a state in which the linear member 3-41 on which the light emitting elements 1 of the three colors red, green, and blue shown in FIGS. 25 and 26 are arranged is attached to the unit. Similarly to that shown in FIG. 40, each of the corners (A, B, C, D) of the unit shown in FIG. 39B is enlarged (the enlarged view of the corner A is shown in FIG. 41). (A), an enlarged view of the corner B corresponds to FIG. 41 (b),..., And pixels similar to those in the unit are formed between the units connected vertically and horizontally. It is configured so that it can. In this configuration, the number of the linear members 3-41 does not need to be set to a multiple of 6, and may be a multiple of 2. It is also easy to handle fine pitch adjustment.

  If this configuration cannot be used, the size of the unit housing can be adjusted by sliding the housing portion of the unit so that the size of the unit can be easily changed. There is a method of changing the length of the image display surface. That is, it is a method of adjusting the area of the image display surface so that the number of the linear members 3 is a multiple of six.

  So far, when assembling the units, even when the units are connected randomly, the pixels formed between adjacent units (between each unit) have the same configuration as the pixels in the unit, and there is no sense of incongruity So, we have described a method of configuring a unit that can display a good image (compatible), but if this method is difficult (a compatible unit cannot be configured), the unit number etc. It can be handled by attaching and deciding the position.

  As described above, another advantage of the configuration shown in FIG. 41 (in which three light emitting elements 1 are mounted on one linear member 3-41) is as described above. That is, the pitch of the linear member 3-41 can be larger than that of the linear member 3-40 (if the pitch or the pixel pitch is the same). That is, even with the same pixel pitch, the number of the linear members 3-41 can be reduced from the linear members 3-40, the cost can be reduced, and the weight can be reduced.

  Although the linear member 3 shown here has a configuration in which the light emitting elements are arranged in one column (one row), it requires some man-hours when being mounted on the image display unit. In order to reduce this, not only one column (one row) but two columns (two rows) or three columns (three rows) may be used, and the number can be increased. At this time, it is desirable that the column and column (row and row) can be slid to change the interval so that the pitch of the light emitting elements 1 can be changed to some extent. If the light emitting elements 1 of the same color are arranged in 1 column (1 row), 3 columns (3 rows) or 6 columns (6 rows) are sufficient, and the type in which three colors of red, green and blue are arranged. If there are, 2 columns (2 rows), 4 columns (4 rows), 6 columns (6 rows), etc. are desirable. In this configuration, there is a part that must be taken into consideration when displaying a curved image, but since a plurality of linear members 3 can be mounted together, the mounting time is shortened.

  42 to 45 show modified examples of the arrangement method of the light emitting elements 1 constituting the image display surface. FIGS. 42A, 43, 44, and 45 are types in which the light emitting element 1 of two colors is attached to one linear member 3. First, FIG. From -42a, (1) red and green, (2) green and blue, (3) blue and red, (4) red and green,...

  43 shows (1) red and green, (2) blue and red, (3) red and green, (4) blue and red,... Has been.

  44 shows the left side linear member 3-44, (1) red and green, (2) green and blue, (3) red and green, (4) green and blue,... Has been.

  Fig. 45 shows the left side linear member 3-45 (1) Blue and red, (2) Green and blue, (3) Blue and red, (4) Green and blue, ... Has been.

  In FIG. 43, the red light emitting element 1 is twice as large as the other colors, so that red can be displayed strongly. In FIG. 44, the green light-emitting element 1 is twice as large as the other colors, so that green can be displayed strongly. In FIG. 45, the blue light-emitting element 1 is twice as many as the other colors, so that blue can be displayed strongly. In FIG. 42, the red, green, and blue light emitting elements 1 are mounted in a balanced manner.

  42 to 45 are types in which the light emitting element 1 is arranged at the position of the grid, and the arrangement balance is good when the interval between the light emitting elements 1 mounted on the linear member 3 and the interval between the linear members 3 are equal. One light emitting element 1 can form four pixels. This example will be described by focusing on the light-emitting element 1-42 shown in FIG. 42A. Four light-emitting elements 1 arranged at the positions of the grids are arranged at the vertices of a square, and one pixel is arranged. In the light emitting element 1-20, a pixel 5-20 is formed at the upper left, a pixel 5-21 at the lower left, a pixel 5-22 at the lower right, and a pixel 5-23 at the upper right.

  FIG. 42B shows a type in which three color light emitting elements 1 are mounted on one linear member 3-42b, and one light emitting element 1 forms four pixels. This is also the same as FIG. This arrangement method has a good balance of R, G, and B. FIGS. 42A and 42B show an example of an arrangement method in which R, G, and B are well balanced, but the present invention is not limited to this method.

  46 and 47 are diagrams (parts) showing still another arrangement method. This is also an example in which one pixel is formed by four light emitting elements 1, and FIG. 46 shows a case where the light emitting element 1 of a single color is attached to the linear member 3-46.

  FIG. 47 shows a case where the light emitting element 1 of three colors of red, green, and blue is attached to the linear member 3-47. Even in this configuration, one light emitting element 1 can form four pixels.

  Note that although full-color image display has been mainly described so far, even a display device using the two-color light-emitting elements 1 can have the same configuration. Examples thereof are shown in FIGS.

  48 and 49 show a type in which the light-emitting elements 1 are arranged in a fine grid, and FIG. 48 shows a case where the light-emitting elements 1 of a single color are attached to the linear members 3-48.

  FIG. 49 shows a case where the two-color light emitting elements 1 are alternately mounted on the linear member 3-49.

  50 to 52 are the types in which the light emitting elements 1 are arranged in a grid pattern like a grid, and FIG. 50 is a diagram in which the light emitting elements 1 of two colors are alternately mounted on the linear members 3-50, and the light emission is arranged side by side. For element 1, two colors are alternately arranged and red and green are shown in a checkered pattern.

  FIG. 51 shows a case where the light emitting element 1 of a single color is attached to the linear member 3-51.

  FIG. 52 shows a case in which the light emitting elements 1 of two colors are alternately mounted on the linear member 3-52, and the light emitting elements 1 arranged side by side have a single color.

  FIGS. 53 and 54 are diagrams showing a modification of the arrangement method of the light emitting elements 1.

  FIG. 53 shows a case where the light emitting element 1 of a single color is attached to the linear member 3-53.

  FIG. 54 shows a case where the light emitting elements 1 of two colors are alternately mounted on the linear member 3-54.

  48 to 54 shown here are constituted by the light emitting elements 1 of two colors of red and green, but the invention is not limited to these two colors. The same configuration can be achieved by using red and blue or green and blue light emitting elements 1.

  The lighting device can also be configured in the same manner as the image display device described so far. The color of the light-emitting element 1 is generally configured to be white by emitting three colors of red, green, and blue, but may be configured in two colors as shown in FIGS. 48 to 54 described above. . Moreover, white LED etc. which development progresses recently can also be used. The difference from the image display is the shape of the light emitting surface and the change of the shape. Most of the image displays have a rectangular display surface, and it is unlikely that the shape of the rectangle will be greatly changed (for example, a triangle, a trapezoid, etc.). For example, it is conceivable that the illumination device is provided with illumination (light emitting surface) on the entire ceiling of the room. The shape of the entire ceiling surface is not necessarily rectangular. In addition, after the installation, the shape of the light emitting surface may be inevitably changed by installing or moving furniture. The configuration of the light emitting element 1 and the linear member 3 shown in FIGS. 1 and 2 will be described, and the shape of the light emitting surface and a method corresponding to the change in the shape will be described.

  The linear member 3 can be easily cut and connected, and the length of the linear member 3 can be freely changed. In addition, the light emitting element 1 can be easily attached to the linear member 3. For example, the light emitting element 1 can be attached to the newly connected linear member 3. That is, the linear member 3 can be cut out in accordance with the shape of the light emitting surface to form the light emitting surface. If the shape of the light emitting surface is to be changed, the length of the linear member 3 can be changed by cutting and connecting. . Details of this will be described later.

  Examples of lighting devices are shown in FIGS.

  FIG. 55 shows an illumination device having a rectangular light emitting surface that can be installed on the ceiling or wall of a room, for example. 55 is a rectangular light emitting surface for ease of explanation, but the shape is not limited to this shape, and the linear member 3- may also have a curved shape such as a triangle, pentagon, other polygons, a circle, an ellipse, or a parabola. This can be done by adjusting the length of 55.

  FIG. 56 shows a state where the light emitting surface of the illuminating device shown in FIG. 55 is cut off by a dotted line.

  FIG. 57 shows a state in which a light emitting surface with hatched portions is added to the light emitting surface shown in FIG. Cutting may be performed simply by cutting the linear member 3-57, but connecting (adding) requires a little trouble. This can be connected relatively easily by using the connecting means 41 as shown in FIGS. 38 (a) and 38 (b). Of course, a new long linear member 3-57 may be manufactured.

  FIG. 58 shows a state in which the light emitting surface shown in FIG. 55 is divided into two. In FIG. 58, it is divided into two, but it can be divided into three or four. If the part to divide is a unit of the linear member 3-58, it will be easier to divide than to cut the linear member 3-58.

  FIG. 59 shows a state where the inside shown in FIG. 55 is cut and a hole is made. In FIG. 59, there is one hole 45, but a plurality of holes can be provided, and the shape of the hole is not limited to a circle, and can be any shape such as a triangle, a quadrangle, and a cloud shape. it can.

  The light emitting surface of the lighting device shown in FIGS. 55 to 59 is only an example, and can correspond to various shapes. The light emitting surfaces of the illumination devices shown in FIGS. 55 to 59 are all planar types, but may be three-dimensional light emitting surfaces.

  It can also be set as the illuminating device from which the shape of a light emission surface changes in the state which the light emission surface as shown in FIGS. 31-35 is light-emitting.

  In the illumination device, not only a configuration that can move in units of the light emitting elements 1 but also a configuration that moves in units of pixels can be handled. That is, the light emitting elements of the three colors of red, green, and blue are collectively attached to the support member, even if the light emitting element 1 unit described so far is not configured to be attached to the linear member 3 via the support member 13. A substantially similar effect can be obtained by mounting this support member on a linear member so as to be movable in units of pixels. However, in this configuration, it is difficult to provide a reflecting surface.

  The lighting device can be used not only for providing brightness but also for a lighting device having a bactericidal action by using, for example, a light emitting element that emits ultraviolet rays. It is effective that some or all of the light-emitting elements used in the above-described lighting device are of the ultraviolet light emission type and are installed in places where sterilization is necessary, such as kitchens, hospitals, and operating rooms. When some of the light emitting elements are of an ultraviolet light emitting type, for example, the ultraviolet light emitting type is not turned on during business hours, but can be turned on only when it is acceptable to emit ultraviolet light. Moreover, it can also be used for a curtain, warmth, etc. using the string-like linear member 3-23 as shown in FIG.

  On the other hand, it is also effective for night indicator lights at construction sites. For example, when the construction range changes with time, it can be easily handled by widening or narrowing the pitch of the linear members 3. The light-emitting element 1 used in this indicator lamp may be one red color, and of course, it can handle multiple colors. A battery may be provided on each of the linear members 3 to make it portable. When building a high-rise building, it is necessary to provide an indicator light to inform the aircraft of the existence of a building at night, and this is also provided with a light emitting element 1 (linear member 3) at the end of the crane. This can be easily handled. Since the indicator lamp used in such a construction site or the like does not need to strictly adjust the pitch of the light emitting elements 1 and the interval between the linear members 3, the cost can be remarkably reduced as compared with the image display device and the illumination device.

  FIG. 60 is a perspective view (part) of an image display surface or a light emitting surface showing an example in which a solar cell 51 is provided as a means for generating power by light at a portion irradiated with light of the light emitting element 1. In the example shown in FIG. 60, linear members 3-60, to which light emitting elements 1 of three colors R, G, and B are attached in order, are arranged in the horizontal direction, and the light emitting elements 1 of the same color are arranged in the vertical direction. It is the arrangement which is arranged. A solar cell 51 is attached to each of the linear members 3-60, and power is generated by being irradiated with the light emitting element 1, and electricity from the solar cell 51 is supplied to the image display device or the illumination device. The solar cell 51 also has effects such as louvering and reflected light suppression. In FIG. 60, the linear members 3-60 to which the solar cells 51 are attached are arranged in the horizontal direction, but the present invention is not limited to this, and the linear members 3-60 to which the solar cells 51 are attached are arranged vertically. It can also be set as the structure to do. Further, the configuration is not limited to the configuration of mounting on the linear member 3, and the solar cell 51 can be provided as a member different from the linear member 3. Large-sized image display devices and lighting devices require a considerable amount of power, and running costs are a heavy burden on the user. Although the solar cell 51 is provided as one method for solving this problem, the installation location of the solar cell 51 may be provided anywhere as long as the light from the light emitting element 1 is irradiated at a position other than the viewing angle. .
