本考案は、ＬＥＤチップ等の点発光する多数の発光素子を用いて発光ドットを 構成してなるドットマトリクス用発光表示体に関する。 This invention uses a large number of light emitting elements such as LED chips that emit point light to create light emitting dots. The present invention relates to a dot matrix light emitting display formed by the present invention.
【０００２】0002
従来より、ＬＥＤチップ等の点発光する発光素子を用いたドットマトリクス用 光表示体としては、例えば、図７に示すような構成のものが提案されている。 Conventionally, for dot matrix using light emitting elements such as LED chips that emit point light. As an optical display, for example, one having a configuration as shown in FIG. 7 has been proposed.
【０００３】 即ち、このドットマトリクス発光表示体１００は、表示体基板１０１に８×８ のマトリクス状にＬＥＤチップ（不図示）を配設してマトリクス点灯表示回路を 構成し、上記各ＬＥＤチップに対応して透孔１０２が穿孔されたマスク板１０３ を重ね合わせ、各透孔１０２内を透明樹脂１０５にて樹脂封止して８×８の発光 ドット１０４を構成したものである。このようなドットマトリクス発光表示体１ ００では、マスク板１０３の各透孔１０２を除く表面を黒色系の光無反射面とす る一方、各発光ドット１０４を構成する透孔１０２内周面を擂鉢状の白系光反射 面として、所望の表示パターンに応じて点灯する各ＬＥＤチップの光を広範囲に 反射散乱させるようになっている。0003 That is, this dot matrix light emitting display 100 has an 8×8 display substrate 101. LED chips (not shown) are arranged in a matrix to form a matrix lighting display circuit. and a mask plate 103 in which through holes 102 are perforated corresponding to each of the above-mentioned LED chips. are overlapped and the inside of each through hole 102 is sealed with transparent resin 105 to form an 8×8 light emitting area. This is made up of dots 104. Such a dot matrix light emitting display body 1 In 00, the surface of the mask plate 103 excluding each through hole 102 is a black non-reflective surface. On the other hand, the inner peripheral surface of the through hole 102 constituting each luminescent dot 104 is shaped like a mortar to reflect white light. As a surface, the light of each LED chip that lights up according to the desired display pattern can be spread over a wide range. It is designed to reflect and scatter.
【０００４】0004
しかしながら、上記構成のドットマトリクス発光表示体１００では、ＬＥＤチ ップの光を拡散放射させる構造のため、視野角は広くなるが反面明るさが不足す るようになり、主としてドットピッチ１０ｍｍ以下のドットサイズの小さい屋内 用途の小型の表示体に有効であって、特に周囲の明るい屋外に配置される大型の ドットマトリクス発光表示体には不適であった。この種の屋外用途向けに簡単に 対応させるには、上記構成のドットマトリクス発光表示体１００の上面の各発光 ドット１０４に対応してそれぞれ前方に突出する凸レンズ体を載置することも考 えられるが、この場合、発光ドット１０４が大きくなる程レンズ体自身が大径， 大型化するなど様々な欠点が生じ、実用的でないものとなる。 However, in the dot matrix light emitting display 100 having the above configuration, the LED chips are The structure diffuses and emits the light of the top, so the viewing angle is wide, but the brightness is insufficient. Mainly used indoors with small dots with a dot pitch of 10mm or less. It is effective for small-sized displays, especially for large-sized displays placed outdoors with bright surroundings. It was unsuitable for dot matrix luminescent displays. Easy to use for this type of outdoor application In order to correspond, each light emission on the upper surface of the dot matrix light emission display body 100 having the above structure It may also be considered to place convex lens bodies that protrude forward in correspondence with the dots 104. However, in this case, the larger the luminous dot 104, the larger the diameter of the lens body itself. It has various drawbacks such as increased size, making it impractical.

上記課題を解決するために本考案の第１のドットマトリクス用発光表示体は、 発光素子を多数配設した表示体基板上に複数個の透孔を形成したマスク板を接合 し、該透孔内に多数の発光素子を収容して発光ドットを形成してなるドットマト リクス用発光表示体にであって、上記マスク板の表面及び透孔内周面を全て光無 反射面とし、該透孔内の各発光素子に対応してその表面側に凸レンズ成形体を設 けて発光ドットを形成したことを特徴とする。 In order to solve the above problems, the first dot matrix light emitting display of the present invention has the following features: A mask plate with multiple through holes is bonded to a display substrate with a large number of light emitting elements. A dot matrix is formed by accommodating a large number of light emitting elements in the through holes to form light emitting dots. The surface of the mask plate and the inner peripheral surface of the through hole are all lightless. A reflective surface, and a convex lens molded body is provided on the surface side corresponding to each light emitting element in the through hole. It is characterized by forming luminescent dots.
【０００６】 また、本考案の第２のドットマトリクス用発光表示体は、発光素子を多数配設 した表示体基板上に複数個の透孔を形成したマスク板を接合し、該透孔内に多数 の発光素子を収容して発光ドットを形成してなるドットマトリクス用発光表示体 であって、上記マスク板の表面及び透孔内周面を全て光無反射面とし、該透孔内 の各発光素子の一つ以上に対応して表面側横方向にそれぞれに棒状凸レンズ成形 体を設けて発光ドットを形成したことを特徴とする。[0006] In addition, the second dot matrix light emitting display of the present invention has a large number of light emitting elements.

【０００７】[0007]
上記構成の第１のドットマトリクス用発光表示体では、マスク板の表面及び穿 孔された各透孔内周面を全て光無反射面とすると共に、各透孔内の各発光素子に 対応してその表面側に凸レンズ成形体を設けて発光ドットを形成しているため、 該凸レンズ成形体によって各発光素子より発する光の指向性が上下左右共集光さ れて中心点に向かった均一方向の鋭いものとなり、且つ上記マスク板の効用によ り隣接する発光ドットに対して光の漏れが低減され、各発光素子の点灯・消灯時 の表示パターンのコントラストが向上する。また、第２の発光表示体では、一つ 以上の発光素子に対応して設けられる横方向の棒状レンズ成形体によって各発光 素子より発する光が上下方向が均一に集光して絞られるようになり、上記同様に マスク板の効用により隣接する発光ドットに対する光の漏れが低減され、各発光 素子の点灯・消灯時の表示パターンのコントラストが向上する。 In the first dot matrix light emitting display having the above structure, the surface of the mask plate and the perforations are The inner circumferential surface of each hole is made into a non-reflective surface, and each light emitting element inside each hole is Correspondingly, a convex lens molded body is provided on the surface side to form light emitting dots, so The convex lens molded body allows the directivity of the light emitted from each light emitting element to be focused both vertically and horizontally. It becomes sharp in the uniform direction toward the center point, and due to the effectiveness of the mask plate, This reduces light leakage to adjacent light emitting dots, making it easier to turn on and off each light emitting element. The contrast of the display pattern is improved. In addition, in the second light emitting display, one Each light emitted by a horizontal rod-shaped lens molded body provided corresponding to the above light emitting elements. The light emitted from the element is now focused and focused evenly in the vertical direction, and as above, The effectiveness of the mask plate reduces light leakage to adjacent light emitting dots, and each light emitting dot The contrast of the display pattern when the element is turned on and off is improved.
【０００８】 従って、上記何れの発光表示体であっても縦横に多数枚配置してそれぞれの発 光表示体自体を一つの発光ドットとして点灯表示する大型のドットマトリクス発 光表示体とした場合、各発光表示体による実用視認位置での表示輝度を向上させ られるので周囲の明るい屋外に配置してもドットマトリクス発光表示体における 表示パターンの視認性が高まり且つ、点灯・消灯時のコントラストが向上するよ うになる。[0008] Therefore, no matter which of the above light-emitting displays are used, a large number of light-emitting displays can be arranged vertically and horizontally, each emitting A large dot matrix display that lights up the light display itself as a single light emitting dot. When used as a light display, the display brightness at the practical viewing position of each light-emitting display can be improved. This allows the dot matrix light-emitting display to be used even when placed outdoors in bright surroundings. This increases the visibility of the display pattern and improves the contrast when turning on and off. I'm going to growl.

There is. The convex lens molded body 11 is made of a translucent resin such as silicone rubber as described above. It is formed into a semi-elliptical cross-sectional shape, and each light emitting element 51, 52 and each convex lens The center points of the molded body 11 are made to substantially coincide with each other, and the two are molded into one piece by, for example, thermosetting. There is. The light emitted by each light emitting element 51, 52 is transmitted by each convex lens molded body 11. It focuses the light and suppresses the scattering of light in the vertical, horizontal, and horizontal directions, resulting in sharp directivity. Na In addition, without placing the tip of each convex lens molded body 11 inside the mask plate 4, at least Even if the mask plate 4 is made to protrude with a length of about 1/3 or less of the thickness, the light condensing property and adjacent This makes it possible to prevent light leakage from the cutter. In addition, the cross-sectional shape of the convex lens molded body 11 is shown in the figure. The center line of each light emitting element 51, 52 is not limited to a semi-elliptical shape such as It can be changed to various shapes that provide upward directivity, and each The corresponding arrangement of the optical elements 51, 52 and the convex lens molded body 11 is slightly changed depending on each. It goes without saying that the directional characteristics of the light emitting dots can be changed by providing Nor. Further, depending on the case, a light diffusing agent may be mixed into the resin. And each shot After integrally molding convex lens moldings corresponding to the optical elements 51 and 52 on the sheet in advance, It can be integrally molded with the translucent resin 10 by heating, or it can be molded into each convex lens molded body 11 in advance. Using a mold or the like that has been cut out accordingly, each light emitting element 51, 52 is sealed with resin and a convex layer is formed. The convex lens molded body 1 is formed through various manufacturing processes, such as molding the lens molded body 11 at the same time. 1, and the means for producing this convex lens molded body 11 is not particularly limited. It is not determined. Moreover, this convex lens molded body 11 is made of rubber elastic material as described above. It is preferable to use a hard plastic molded article.
【００１４】 上記構成の発光表示体１では、各発光ドット６内に樹脂封止されたそれぞれの 発光素子５１及び各発光素子５２を同時に点灯・消灯する点灯制御回路を構成と することで、例えば、各発光素子５１を点灯して２×２の発光ドット６をそれぞ れ赤色発光させたり、また、各発光素子５２を点灯して各発光ドット６をそれぞ れ緑色発光させたり、更には発光素子５１，５２を全て点灯して発光ドット６を 混合色である略黄色に発光させることができる。[0014] In the light-emitting display body 1 having the above structure, each light-emitting dot 6 is sealed with resin. A lighting control circuit is configured to simultaneously turn on and off the light emitting element 51 and each light emitting element 52. By doing so, for example, each light emitting element 51 is lit to create a 2×2 light emitting dot 6. or each light emitting element 52 is turned on to make each light emitting dot 6 emit red light. The light-emitting dot 6 can be emitted by lighting up all the light-emitting elements 51 and 52. It can emit light in a mixed color, approximately yellow.
【００１５】 このような発光表示体１では、各発光ドット６に樹脂封止される各発光素子５ １，５２に対応させて凸レンズ成形体１１を成形一体としているため、各発光素 子５１，５２からの光がそれぞれ凸レンズ成形体１１によって上下左右両方向は 勿論周囲に向かって発する光が中心方向へビーム状に絞られて光が集光放射され 、その分だけ明るさが大幅に増し、かつ中心方向の一定した均一な指向性が得ら れるようになる。また、各発光ドット６内の発光素子５１，５２は黒色系の光無 反射面としたマスク板４の透孔３内に収容されているため、隣接する発光ドット ６へ光が漏れ難く、凸レンズ成形体１１による光の指向性の向上に伴い、隣設さ れる発光ドット６から発せられる光との干渉が起こり難く、各発光ドット６の明 瞭さが確保されるようになる。そして、マスク板４自体が黒色系又は灰色系の光 無反射面となっているため、それぞれの発光ドット６の点灯時と消灯時とのコン トラストも良好となる。その上、マスク板４がゴム弾性体であり、透孔３内の各 発光素子５１，５２を封止した透光性樹脂１０もシリコーンゴム等のゴム弾性体 であるため、各発光素子５１，５２の発光による発熱や反り等による歪みや内部 応力を吸収すると共に、封止樹脂による放熱性も良好となる。この効果は凸レン ズ成形体１１もゴム弾性体とすることにより効果的となる。[0015] In such a light emitting display 1, each light emitting element 5 is sealed with resin in each light emitting dot 6. Since the convex lens molded body 11 is integrally molded in correspondence with the light emitting elements 1 and 52, each light emitting element The light from the lenses 51 and 52 is reflected in both the vertical and horizontal directions by the convex lens molded body 11, respectively. Of course, the light emitted toward the surroundings is condensed into a beam toward the center and emitted. , the brightness increases significantly, and uniform directivity in the center direction can be obtained. You will be able to do it. In addition, the light emitting elements 51 and 52 in each light emitting dot 6 have a black colorless light. Since it is accommodated in the through hole 3 of the mask plate 4 which serves as a reflective surface, adjacent light emitting dots 6, and the convex lens molded body 11 improves the directivity of light. Interference with the light emitted from the light-emitting dots 6 is difficult to occur, and the brightness of each light-emitting dot 6 is Clarity will be ensured. Then, the mask plate 4 itself emits black or gray light. Since it is a non-reflective surface, there is no contrast between when each luminous dot 6 is lit and when it is turned off. Trust will also be good. Moreover, the mask plate 4 is made of a rubber elastic body, and each of the through holes 3 is The light-transmitting resin 10 that seals the light-emitting elements 51 and 52 is also made of rubber elastic material such as silicone rubber. Therefore, distortion and internal damage due to heat generation and warpage due to the light emission of each light emitting element 51, 52, etc. In addition to absorbing stress, the sealing resin also improves heat dissipation. This effect is a convex lens. It becomes more effective if the rubber molded body 11 is also made of a rubber elastic body.
【００１６】 さらに、凸レンズ成形体１１が各発光素子５１，５２に個々に対応して設けら れているため、同一の凸レンズ効果を出すためのレンズ径、レンズ高さを小さく することができるため、従って、マスク板４の厚みも薄くでき、全体として薄型 の発光表示体１とすることができる。[0016] Further, a convex lens molded body 11 is provided corresponding to each light emitting element 51, 52 individually. Therefore, the lens diameter and lens height can be reduced to achieve the same convex lens effect. Therefore, the thickness of the mask plate 4 can be reduced, and the overall thickness can be reduced. The light emitting display body 1 can be made into the following.
【００１７】 図３，図４及び図５は何れも本考案の第２の実施例に係るドットマトリクス用 発光表示体２０であり、図４は図３におけるＢ−Ｂ線に沿った概略断面図、図５ は図４におけるＣ−Ｃ線に沿った概略断面図を示している。この発光表示体２０ は、前記発光表示体１と発光素子５１，５２の配置と、樹脂封止された各発光素 子５１，５２の表面側に設けられた棒状レンズ成形体２１を除き、他の構成は実 質的に発光表示体１と同一であるため、同一部材には同一符号を付してここでは 説明を省略し、棒状レンズ成形体２１について説明する。[0017] 3, 4 and 5 are all for the dot matrix according to the second embodiment of the present invention. 4 is a schematic cross-sectional view taken along line BB in FIG. 3, and FIG. 5 is a light emitting display body 20. shows a schematic cross-sectional view taken along the line CC in FIG. 4 . This light emitting display body 20 The arrangement of the light-emitting display body 1 and the light-emitting elements 51 and 52 and the resin-sealed light-emitting elements are shown below. Except for the rod-shaped lens molded body 21 provided on the surface side of the lenses 51 and 52, the other components are actually Since it is qualitatively the same as the light emitting display 1, the same members are given the same reference numerals and will be referred to here. The explanation will be omitted and the rod-shaped lens molded body 21 will be explained.
【００１８】 即ち、棒状レンズ成形体２１は、表示体基板２に配設された発光色の異なる各 発光素子５１，５２のうち、横方向に配列された一つ以上の各発光素子５１，５ ２に対応して表面側に設けられたもので、略半楕円形断面を有するシリコーンゴ ム等の透明樹脂弾性体であり、透孔３内の上下５箇所にそれぞれ長さを異ならせ て並設されており、各発光素子５１，５２に対応して棒状レンズ成形体２１の中 心線を略一致させた状態で成形一体としている。この場合、棒状レンズ成形体２ １は上記凸レンズ成形体１１と同様ゴム弾性体とするのが好ましいが、硬質プラ スチック成形品であってもよい。[0018] That is, the rod-shaped lens molded body 21 is arranged on the display substrate 2 to emit light of different colors. Among the light emitting elements 51 and 52, one or more of the light emitting elements 51 and 5 arranged in the horizontal direction A silicone rubber with an approximately semi-elliptical cross section is provided on the surface side corresponding to 2. It is a transparent resin elastic body such as a transparent resin material, and has different lengths at five locations above and below inside the through hole 3. They are arranged in parallel in the rod-shaped lens molded body 21 corresponding to each light emitting element 51, 52. It is integrally molded with the core wires substantially aligned. In this case, the rod-shaped lens molded body 2 1 is preferably made of a rubber elastic body similar to the above-mentioned convex lens molded body 11, but it is preferable to use a hard plastic. It may also be a stick molded product.
【００１９】 このような発光表示体２０では、発光表示体１と同様に表示体基板２上に配設 される各発光素子５１，５２で点灯表示回路を構成し、各発光ドット６内の全て の発光素子５１の点灯・消灯や、各発光ドット６内の全ての発光素子５２の点灯 ・消灯、又は全ての発光素子５１，５２の点灯・消灯を制御して発光表示体２０ を点灯制御することができる。このとき、各発光素子５１，５２の表面側に設け られた棒状レンズ成形体２１によって上下方向に発する光が中心線に向かって集 光して絞られるが、実用上有用な左右方向へ発する光は狭められないため、不要 な上下方向の視野角が狭められない分だけ実質的な明るさが増し、実用視認位置 での視認性が向上する。そして、各発光素子５１，５２と棒状レンズ成形体２１ の中心線を略一致させることにより、どの発光素子５１，５２が点灯されても指 向性が上下に変化することなく一定で均一となり、見る方向によって明度が低下 することはない。特に、横列の発光素子５１，５２を同時に点灯した場合に、合 成色の色相や明度が見る方向によって変化することがなく、均一となる。そして 、各発光ドット６内の発光素子５１，５２は黒色系の光無反射面となったマスク 板４の透孔３内に収容されているため、隣接する発光ドット６に光が漏れ難く、 各発光ドット６点灯・消灯におけるコントラストも十分に得られる。[0019] In such a light-emitting display body 20, like the light-emitting display body 1, a The light-emitting elements 51 and 52 constitute a lighting display circuit, and all of the light-emitting elements 51 and 52 in each light-emitting dot 6 Turning on/off the light-emitting elements 51 and lighting all the light-emitting elements 52 in each light-emitting dot 6 ・The light-emitting display body 20 is turned off, or by controlling the lighting/extinguishing of all the light-emitting elements 51 and 52. The lights can be controlled. At this time, each light emitting element 51, 52 is provided with a The light emitted in the vertical direction is focused toward the center line by the rod-shaped lens molded body 21. Although the light emitted in the left and right directions, which is useful for practical purposes, is not narrowed, it is unnecessary. The actual brightness increases to the extent that the vertical viewing angle is not narrowed, making it easier to see at a practical viewing position. Improves visibility. Then, each light emitting element 51, 52 and the rod-shaped lens molded body 21 By substantially matching the center lines of the The tropism remains constant and uniform without changing up or down, and the brightness decreases depending on the viewing direction. There's nothing to do. In particular, when the light emitting elements 51 and 52 in the horizontal row are turned on at the same time, the combination The hue and brightness of the coloring do not change depending on the viewing direction and are uniform. and , the light-emitting elements 51 and 52 in each light-emitting dot 6 are masked with a black non-reflecting surface. Since it is housed in the through hole 3 of the plate 4, light hardly leaks to the adjacent light emitting dots 6. Sufficient contrast can also be obtained when each light-emitting dot 6 is turned on and off.
【００２０】 さらに、棒状レンズ成形体２１が各発光素子５１，５２の棒状配列毎に対応し て設けられているため、本考案の上記実施例同様棒状レンズ体の径及び高さを薄 くでき、従って、薄型発光表示体２０とすることができる。[0020] Furthermore, a rod-shaped lens molded body 21 corresponds to each rod-shaped arrangement of the light emitting elements 51 and 52. Therefore, the diameter and height of the rod-shaped lens body can be reduced as in the above embodiment of the present invention. Therefore, a thin light emitting display 20 can be obtained.
【００２１】 また、この発光表示体２０でも発光表示体１と同様に、マスク板４と各発光素 子５１，５２を封止した透光性樹脂１０がシリコーンゴム等の弾性体であるため 、発光素子５１，５２の発光による発熱や反り等による歪みや内部応力を吸収す ると共に、封止樹脂による放熱性も良好となる。この効果は棒状レンズ成形体２ １もゴム弾性体とすることにより、より効果的となる。[0021] Also, in this light-emitting display body 20, similarly to the light-emitting display body 1, the mask plate 4 and each light-emitting element are connected to each other. Because the transparent resin 10 that seals the elements 51 and 52 is an elastic body such as silicone rubber. , to absorb distortion and internal stress due to heat generation and warpage caused by light emission of the light emitting elements 51 and 52. At the same time, the heat dissipation by the sealing resin is also improved. This effect can be seen in the rod-shaped lens molded body 2. If 1 is also made of rubber elastic body, it becomes more effective.
【００２２】 上記した何れの発光表示体１，２０も形成された２×２の発光ドット６の点灯 ・消灯によってコントラストの十分な発光表示体となるものであり、例えば、図 ６に示すように、この発光表示体１を縦横に８枚づづ並べ、２×２の４箇所の発 光ドット６を有する各発光表示体１を一つの発光ドット３０として８×８の大型 のドットマトリクス発光表示体４０を構成することができる。この場合、各発光 表示体１の発光ドット６をそれぞれ同時に点灯・消灯する点灯制御と共に、更に ＣＰＵ等で構成されるコントローラ（図示せず）のプログラムに従って各発光表 示体１を点灯制御することで所望の文字、図形、記号等の表示パターンを点灯表 示できるようになる。[0022] Lighting of the 2×2 luminescent dots 6 formed with any of the luminescent display bodies 1 and 20 described above ・When the light is turned off, it becomes a light-emitting display with sufficient contrast, for example, As shown in Fig. 6, 8 pieces of this light emitting display 1 are arranged vertically and horizontally, and the light emitting display bodies 1 are arranged in 4 places of 2 x 2. Each light-emitting display body 1 having a light dot 6 is treated as one light-emitting dot 30 in a large size of 8×8. A dot matrix light-emitting display body 40 can be constructed. In this case, each emission In addition to lighting control for simultaneously lighting and extinguishing the light-emitting dots 6 of the display body 1, Each light emitting table is controlled according to the program of a controller (not shown) consisting of a CPU, etc. By controlling the lighting of Display 1, the desired display pattern of characters, figures, symbols, etc. can be displayed on the lighting table. be able to show

It is installed and used appropriately, and each 2 x 2 luminescent dot 6 of the luminescent display 1 above The light emitted from the convex lens molded on the surface side corresponds to each light emitting element 51, 52. The brightness is improved by the body 11 and the directivity becomes sharper, and the contrast with the mask plate 4 is improved. Since the trust is also good, there is no leakage of light between the light emitting displays 1 arranged vertically and horizontally. It is said that the desired display pattern becomes blurry and difficult to see, reducing visibility. This eliminates the problems of This makes it possible to create a dot matrix light-emitting display. In addition, due to the light emission of each light emitting display body 1, Distortion and internal stress caused by heat generation and warping are absorbed, and because it is integrally molded, it has good heat dissipation. Since they are so good, these problems do not occur even if a large number of them are arranged vertically and horizontally.
【００２４】 尚、発光表示体２０を上記発光表示体１と同様に用いると、各発光表示体２０ が実用上有用な左右方向の視野角が確保されて明るさが向上し、隣接する発光表 示体２０間で光の漏れを生じず、所望の表示パターンの視認性が低下することも ない。[0024] Incidentally, when the light emitting display body 20 is used in the same manner as the light emitting display body 1 described above, each light emitting display body 20 This ensures a practically useful left and right viewing angle, improves brightness, and allows you to see the adjacent light emitting surface. No light leakage occurs between the displays 20, and the visibility of the desired display pattern may be reduced. do not have.

A light-emitting device with improved contrast when the optical elements 51 and 52 turn on and off. This is preferable because the cut 6 can be configured.
【００２６】 さらに、各発光表示体１及び２０は２×２の４箇所の発光ドット６を有するも のとしたが、これに限らず、各発光表示体に４×４や８×８またはそれ以上の発 光ドット６を縦横に形成しても何等問題はないが、この発光表示体を縦横に配列 して更にドットマトリクス状の発光表示体を構成したときの各発光ドットとする 点を考慮すると、各発光表示体は縦横２×２から８×８の発光ドット６で構成す ることが好ましい。[0026] Furthermore, each light-emitting display body 1 and 20 has four light-emitting dots 6 of 2×2. However, the present invention is not limited to this, and each light-emitting display may have 4×4, 8×8 or more light-emitting displays. There is no problem if the optical dots 6 are formed vertically and horizontally, but if the light emitting display bodies are arranged vertically and horizontally, and each luminescent dot when a dot matrix luminescent display body is constructed. Taking this point into consideration, each light-emitting display body is composed of light-emitting dots 6 with dimensions ranging from 2 x 2 to 8 x 8 in the vertical and horizontal directions. It is preferable that
