Description
本発明は、多数の画素を配列して構成する映像表示装置に関するものである。 The present invention relates to a video display device configured by arranging a large number of pixels.
映像表示装置はＬＥＤなどの固体光源を多数配列して構成する表示ユニットを縦横方向に多数タイリングした構成である。映像表示装置を屋外で使用する場合、固体光源が配列された基板をハウジングケースに組み込み、防水用の樹脂等を充填することにより、表示ユニットを構成し、基板及び固体光源電極部の防水を実施している。 The video display device has a configuration in which a large number of display units that are configured by arranging a large number of solid-state light sources such as LEDs are tiled in the vertical and horizontal directions. When the video display device is used outdoors, a display unit is constructed by incorporating a substrate with a solid light source arrayed in a housing case and filling with a waterproof resin, etc., and the substrate and the solid light source electrode section are waterproofed. doing.
高精細な映像表示装置を実現するためには、ＬＥＤなどの固体光源を高密度に基板上に配列させる必要がある。また、同時に映像表示装置において、均一で高画質な画像を得るためには、表示ユニット内の固体光源配列ピッチと表示ユニット間の固体光源配列ピッチを同一にする必要がある。これらのピッチが同一でない場合、表示ユニット間の目地が目立ち、表示画面上に格子状の明暗の線が現れ、画質を劣化させる原因となる。 In order to realize a high-definition image display device, it is necessary to arrange solid-state light sources such as LEDs on a substrate with high density. At the same time, in order to obtain a uniform and high-quality image in the video display device, it is necessary to make the solid light source arrangement pitch in the display unit the same as the solid light source arrangement pitch between the display units. If these pitches are not the same, the joints between the display units are conspicuous, and grid-like light and dark lines appear on the display screen, which causes the image quality to deteriorate.
このように、屋外環境において高精細で高画質の映像表示装置を得るためには、固体光源が高密度に配列された基板をハウジングケースに組み込み、かつ表示ユニット内の固体光源配列ピッチと表示ユニット間の固体光源配列ピッチを同一にする必要がある。
固体光源を高密度に基板へ配列し高精細化するためには、固体光源の配列ピッチを小さくするとともに、ハウジングケースの外周壁の肉厚も薄くすることが要求される。
As described above, in order to obtain a high-definition and high-quality video display device in an outdoor environment, a substrate on which solid light sources are arranged at high density is incorporated in a housing case, and the solid light source arrangement pitch in the display unit and the display unit The solid light source array pitch between them must be the same.
In order to achieve high definition by arranging solid light sources on a substrate with high density, it is required to reduce the arrangement pitch of the solid light sources and to reduce the thickness of the outer peripheral wall of the housing case.
従来はハウジングケース外周壁の肉厚の制限により、固体光源の高密度化にも限界があった。また、固体光源の高密度化のために、無理に外周壁の肉厚を薄く形成しようとすると、ハウジングケースの樹脂成形時や金属成形時に、外周壁となる部分への充填不足の問題が生じていた。ハウジングケースが不十分な形状として形成された場合、その外周壁を枠体として防水樹脂を充填して得られた防水樹脂は、防水機能を満足することができないという問題があった。また、ハウジングケース外周壁の肉厚が薄すぎると、ハウジングケースの成形ができたとしても、外周壁部分の強度不足により、壁の倒れや割れが生じやすくなるという問題があった。 Conventionally, the density of the solid light source has been limited due to the limitation of the wall thickness of the outer peripheral wall of the housing case. In addition, if the thickness of the outer peripheral wall is forcibly reduced in order to increase the density of the solid state light source, there will be a problem of insufficient filling of the portion that becomes the outer peripheral wall during resin molding or metal molding of the housing case. It was. When the housing case is formed in an insufficient shape, the waterproof resin obtained by filling the outer peripheral wall with the waterproof resin with the frame body cannot satisfy the waterproof function. Further, if the thickness of the outer peripheral wall of the housing case is too thin, there is a problem that even if the housing case can be formed, the wall tends to collapse or crack due to insufficient strength of the outer peripheral wall portion.
一方、防水用の樹脂として高流動性のものを用いることや、ハウジングケースを金属製とする、あるいは固体樹脂や固体金属を削り出すことにより形成することで、ハウジングケース外周部の厚み不足を補い、固体光源を高密度に配列する方法も考えられる。しかし、これらの方法を用いることは、高コスト化の要因となり、量産には不向きであるという問題があった。 On the other hand, by using a highly fluid resin as a waterproof resin, or by forming the housing case by metal, or by cutting out solid resin or solid metal, it compensates for the insufficient thickness of the outer periphery of the housing case. A method of arranging the solid light sources at high density is also conceivable. However, the use of these methods has been a cause of cost increase and is not suitable for mass production.
本発明は、上記のような問題点を鑑み、ハウジングケースの外周壁の厚みを抑制しつつ、外周壁の強度を確保することが可能な映像表示装置の構造を提供することを目的としている。 In view of the above problems, an object of the present invention is to provide a structure of a video display device capable of ensuring the strength of the outer peripheral wall while suppressing the thickness of the outer peripheral wall of the housing case.
この発明に係わる映像表示装置は、複数の固体光源が行列配置された平板状の基板、上記基板を載置する基板支持部と上記基板の外周を取り囲む外周壁を有するハウジングケース、上記外周壁で囲まれた上記基板上の領域に充填された防水樹脂を備え、上記ハウジングケースは、上記外周壁の内側に突出するとともに上記外周壁の高さ方向に伸びる中実柱状の突起部を有し、上記基板の外周部には、上記突起部を収める切り欠き部が形成され、上記切り欠き部は、上記基板上の隣り合う上記固体光源間に設けられたことを特徴とするものである。
An image display device according to the present invention includes a flat substrate on which a plurality of solid light sources are arranged in a matrix, a substrate support portion on which the substrate is placed, a housing case having an outer peripheral wall surrounding the outer periphery of the substrate, and the outer peripheral wall. It is provided with a waterproof resin filled in a region on the surrounded substrate, and the housing case has a solid columnar protrusion protruding inward of the outer peripheral wall and extending in the height direction of the outer peripheral wall , A cutout portion for accommodating the protrusion is formed on the outer peripheral portion of the substrate, and the cutout portion is provided between the adjacent solid light sources on the substrate.
この発明の映像表示装置によれば、高精細化のためにハウジングケースの外周壁の厚みを小さくしても、外周壁の内側に突起部を設けたことで、外周壁の強度を確保することが可能となる。 According to the video display device of the present invention, even if the thickness of the outer peripheral wall of the housing case is reduced for high definition, the strength of the outer peripheral wall can be ensured by providing the protrusion on the inner side of the outer peripheral wall. Is possible.
実施の形態１．
本発明の映像表示装置について図１から図３を参照して説明する。
図１は、映像表示装置１の構成図であり、映像を表示する画面を前面として示した斜視図である。映像表示装置１は、多数の表示ユニット２をタイリングすることによって構成される。
図２は、一般的な表示ユニット２の構造を示す図であり、図２（ａ）は表示ユニット２の前面、図２（ｂ）は表示ユニット２の側面、図２（ｃ）は、図２（ａ）のＡ−Ａ断面を示す図である。さらに、図２（ｄ）は、図２（ａ）から遮光ルーバ７を取り去った表示ユニット２の上面図をそれぞれ示している。
Embodiment 1 FIG.
The video display apparatus of the present invention will be described with reference to FIGS.
FIG. 1 is a configuration diagram of the video display device 1 and is a perspective view showing a screen for displaying video as a front surface. The video display device 1 is configured by tiling a large number of display units 2.
2A and 2B are diagrams showing the structure of a general display unit 2. FIG. 2A is a front view of the display unit 2, FIG. 2B is a side view of the display unit 2, and FIG. It is a figure which shows the AA cross section of 2 (a). Furthermore, FIG.2 (d) has each shown the top view of the display unit 2 which removed the light-shielding louver 7 from Fig.2 (a).
図２に示すように、表示ユニット２は、発光ダイオード（ＬＥＤ）などの固体光源３を多数配列した基板４、基板４を支持し固定するハウジングケース５、基板４及び固体光源３の電極部を防水するために充填された防水樹脂６によって主に構成されている。また、映像表示装置１のコントラストを高めるため、表示ユニット２前面に遮光ルーバ７が取り付けられている。
ハウジングケース５は、図２（ｃ）に示すように、基板４を載置する基板支持部５ａと、基板支持部５ａの外周を取り囲み、基板４上に防水樹脂６を充填する際の枠体となる外周壁５ｂを備えている。外周壁５ｂの厚みは、図２（ｄ）に示すように、全周に亘って同じ寸法である。また、遮光ルーバ７は、固体光源３を露出させた状態となるように基板４上に配置される平板部７ａと、その平板部７ａから前方に突き出し、外光を遮る庇部７ｂを備えている。
As shown in FIG. 2, the display unit 2 includes a substrate 4 on which a large number of solid light sources 3 such as light emitting diodes (LEDs) are arranged, a housing case 5 that supports and fixes the substrate 4, and electrode portions of the substrate 4 and the solid light sources 3. It is mainly constituted by a waterproof resin 6 filled for waterproofing. In order to increase the contrast of the video display device 1, a light shielding louver 7 is attached to the front surface of the display unit 2.
As shown in FIG. 2 (c), the housing case 5 surrounds the outer periphery of the substrate support portion 5 a on which the substrate 4 is placed and the substrate support portion 5 a and fills the substrate 4 with the waterproof resin 6. The outer peripheral wall 5b is provided. The thickness of the outer peripheral wall 5b is the same dimension over the entire circumference as shown in FIG. 2 (d). Further, the light shielding louver 7 includes a flat plate portion 7a disposed on the substrate 4 so that the solid light source 3 is exposed, and a flange portion 7b protruding forward from the flat plate portion 7a to block outside light. Yes.
図２（ｄ）に示すように、遮光ルーバ７を取り去った表示ユニット２では、基板４の平面に固体光源３が行列配置（４×４個）されるとともに、基板４上のハウジングケース５の外周壁５ｂの内側には防水樹脂６が、固体光源３間を埋設するように充填されている。 As shown in FIG. 2D, in the display unit 2 from which the light shielding louver 7 is removed, the solid light sources 3 are arranged in a matrix (4 × 4) on the plane of the substrate 4, and the housing case 5 on the substrate 4 is arranged. A waterproof resin 6 is filled inside the outer peripheral wall 5b so as to embed between the solid light sources 3.
次に、図３に、本発明の映像表示装置１の表示ユニット２を示して説明する。図３の表示ユニット２では、画像の高精細化のために、１つの表示ユニット２内に配置する固体光源３の個数が図２のものよりも多くなっている（６×６個）。そのため、表示ユニット２の面積を図２のものと同一とした場合に、図３に示す本発明の表示ユニット２では、固体光源３間のピッチが小さくなる。図３（ｃ）の図面上部に示すように、ハウジングケース５の外周壁５ｂは、画素の高精細化に伴って、高精細化以前のもの（図２）よりも厚さが薄くなる。そこで、本発明の表示ユニット２では、ハウジングケース５の外周壁５ｂの厚みが減少したとしても、部分的に外周壁５ｂの厚さを増大させることにより、外周壁５ｂの強度を確保することが可能な構造を提案する。 Next, FIG. 3 shows and describes the display unit 2 of the video display device 1 of the present invention. In the display unit 2 of FIG. 3, the number of solid light sources 3 arranged in one display unit 2 is larger than that of FIG. 2 (6 × 6) in order to increase the definition of the image. Therefore, when the area of the display unit 2 is the same as that of FIG. 2, the pitch between the solid light sources 3 is reduced in the display unit 2 of the present invention shown in FIG. As shown in the upper part of FIG. 3C, the outer peripheral wall 5b of the housing case 5 becomes thinner than the one before the high definition (FIG. 2) as the pixels become higher in definition. Therefore, in the display unit 2 of the present invention, even if the thickness of the outer peripheral wall 5b of the housing case 5 is reduced, the strength of the outer peripheral wall 5b can be ensured by partially increasing the thickness of the outer peripheral wall 5b. A possible structure is proposed.
図３に示すように、本発明の映像表示装置１では、ハウジングケース５には外周壁５ｂの内壁面から内側に突出する筋状の突起部５１が設けられ、部分的に外周壁５ｂの厚さが増した状態となっている。そして、この突起部５１は、外周壁５ｂの強度を増大させる補強リブの役割を果たしている。そのため、ハウジングケース５の外周壁５ｂの厚みが小さくなっても、突起部５１によって、外周壁５ｂの強度を確保することが可能となる。
筋状の突起部５１は、ハウジングケース５の基板支持部５ａから立ち上がる外周壁５ｂの高さ方向（枠体の高さ方向）に直線的に形成され、例えば、外周壁５ｂの全高さに亘って図３（ｄ）に示した突出形状となるように形成される。
図３（ｃ）に示すように、突起部５１が形成された部分（図面下部）では、外周壁５ｂの厚さｄが、外周壁５ｂの他部（図面上部、符号５ｂで指し示す部分）の肉厚よりも大きくなり、突起部５１形成部の外周壁５ｂの強度が増していることが分かる。
As shown in FIG. 3, in the video display device 1 of the present invention, the housing case 5 is provided with a streak-like protrusion 51 protruding inward from the inner wall surface of the outer peripheral wall 5b, and the thickness of the outer peripheral wall 5b is partially provided. It is in an increased state. And this protrusion part 51 has played the role of the reinforcement rib which increases the intensity | strength of the outer peripheral wall 5b. Therefore, even if the thickness of the outer peripheral wall 5b of the housing case 5 is reduced, the strength of the outer peripheral wall 5b can be ensured by the protrusion 51.
The line-shaped protrusion 51 is linearly formed in the height direction of the outer peripheral wall 5b rising from the substrate support portion 5a of the housing case 5 (the height direction of the frame), and extends over the entire height of the outer peripheral wall 5b, for example. Thus, the protruding shape shown in FIG.
As shown in FIG.3 (c), in the part (lower part of drawing) in which the projection part 51 was formed, the thickness d of the outer peripheral wall 5b is the other part (upper part of the drawing, the part shown with the code | symbol 5b) of the outer peripheral wall 5b. It turns out that it becomes larger than thickness and the intensity | strength of the outer peripheral wall 5b of the projection part 51 formation part is increasing.
ここで、突起部５１をハウジングケース５の外周壁５ｂの内側に突出させて形成する場合に、ハウジングケース５の基板支持部５ａ上に載置する基板４の外周部と、突起部５１との干渉を避けるために、基板４の外周部に切り欠き部４１を形成する。この切り欠き部４１を基板４の周囲に、突起部５１の配置に合わせて設けることで、ハウジングケース５の突起部５１を切り欠き部４１に収めるように位置合わせして基板４をハウジングケース５に実装することができる。
また、切り欠き部４１は、基板４の外周部の、基板４上に多数搭載された隣り合う固体光源３間（固体光源３間に位置する間隙部で、防水樹脂６が充填される部分）に配置形成される。これにより、固体光源３の配列ピッチに影響を与えることなく、固体光源３間の隙間（非発光領域）を活用したレイアウトが可能となる。
Here, when the protruding portion 51 is formed so as to protrude inside the outer peripheral wall 5 b of the housing case 5, the outer peripheral portion of the substrate 4 placed on the substrate supporting portion 5 a of the housing case 5 and the protruding portion 51 In order to avoid interference, a notch 41 is formed in the outer periphery of the substrate 4. By providing the notches 41 around the substrate 4 in accordance with the arrangement of the protrusions 51, the protrusions 51 of the housing case 5 are aligned so as to be accommodated in the notches 41, and the substrate 4 is placed in the housing case 5. Can be implemented.
In addition, the notch 41 is a portion between the adjacent solid light sources 3 mounted on the substrate 4 at the outer peripheral portion of the substrate 4 (a portion where the waterproof resin 6 is filled in a gap located between the solid light sources 3). Is formed. Thereby, the layout using the gap (non-light emitting area) between the solid light sources 3 is possible without affecting the arrangement pitch of the solid light sources 3.
なお、突起部５１は、外周壁５ｂ（防水樹脂６充填時の枠体）の高さ方向に伸びる柱状であると近似できるが、例えば、その柱状端部であって外周壁５ｂの最も高い部分をＲ状に形成することで、このＲ状の部分が、基板４の実装時にガイドの役割をし、基板挿入作業を容易とすることができる。
また、ハウジングケース５の外周壁５ｂの強度を確保することができれば、突起部５１の突出量が、外周壁５ｂの高さ方向に一様となるように形成されていなくてもよい。
The protrusion 51 can be approximated to have a columnar shape extending in the height direction of the outer peripheral wall 5b (frame body when the waterproof resin 6 is filled). For example, the protrusion 51 is the columnar end and the highest portion of the outer peripheral wall 5b. The R-shaped portion serves as a guide when the substrate 4 is mounted, thereby facilitating the board insertion operation.
Further, as long as the strength of the outer peripheral wall 5b of the housing case 5 can be ensured, the protruding amount of the protrusion 51 may not be formed to be uniform in the height direction of the outer peripheral wall 5b.
上述の図３（ｄ）では、一つの表示ユニット２内において、外側に等ピッチで配置された隣り合う固体光源３間の、全ての箇所（破線で囲んだＢ領域内の、二つの固体光源３に挟まれた間隙部）に、突起部５１および切り欠き部４１を一つずつ配置形成する例を示した。しかし、これに限定することなく、突起部５１を、外周壁５ｂの補強が必要な特定の箇所にのみ形成し、他の箇所には突起部５１を形成しない構造とすることも可能であることは言うまでもない。 In FIG. 3D described above, in one display unit 2, two solid light sources in all locations (B region surrounded by a broken line) between adjacent solid light sources 3 arranged at equal pitches on the outside. In this example, the protrusions 51 and the cutouts 41 are arranged and formed one by one in the gap portion 3). However, the present invention is not limited to this, and it is also possible to have a structure in which the protruding portion 51 is formed only at a specific location where the outer peripheral wall 5b needs to be reinforced and the protruding portion 51 is not formed at other locations. Needless to say.
このように、基板４の外周に切り欠き部４１を、ハウジングケース５の外周壁５ｂの内壁に突起部５１を設けたことにより、基板４に固体光源３が多数個高密度に配列されハウジングケース５の外周壁５ｂの肉厚を薄く形成せざるを得ない場合でも、ハウジングケース５の外周壁５ｂに必要な強度を持たせることができ、防水樹脂６充填の際の枠体としての役割を果たすことが可能となる。よって、防水樹脂６を良好な条件下で形成することができ、屋内環境はもとより屋外環境においても利用可能な、防水性に優れた高精細な映像表示装置１を得ることができる。
上述したように、ハウジングケース５の外周壁５ｂの突起部５１は、外周壁５ｂの補強リブとしての役割を果たすため、外周壁５ｂの倒れや割れなどの破損を防止することができ、ハウジングケース５の強度を向上させることが可能となる。
As described above, by providing the notches 41 on the outer periphery of the substrate 4 and the protrusions 51 on the inner wall of the outer peripheral wall 5b of the housing case 5, a large number of the solid light sources 3 are arranged on the substrate 4 with high density. Even if the outer peripheral wall 5b of the housing 5 has to be formed thin, the outer peripheral wall 5b of the housing case 5 can be provided with the required strength, and can serve as a frame when the waterproof resin 6 is filled. Can be fulfilled. Therefore, the waterproof resin 6 can be formed under favorable conditions, and a high-definition video display device 1 excellent in waterproofness that can be used not only in an indoor environment but also in an outdoor environment can be obtained.
As described above, the protrusion 51 of the outer peripheral wall 5b of the housing case 5 serves as a reinforcing rib of the outer peripheral wall 5b, so that the outer peripheral wall 5b can be prevented from being damaged such as falling or cracking. The strength of 5 can be improved.
実施の形態２．
先述の実施の形態１では、図３（ｄ）に、表示ユニット２内の隣り合う固体光源３の間に位置する間隙部を領域Ｂとして破線で囲んで示していたが、この実施の形態２では、領域Ｂの要部拡大断面図を図４に示し、ハウジングケース５の突起部５１の形状と、基板４の切り欠き部４１の形状についてより詳細に説明する。図４は、図３（ｃ）のＣ−Ｃ断面図に相当し、基板４の上面の高さに沿った断面図である。
Embodiment 2. FIG.
In the first embodiment described above, FIG. 3 (d) shows the gap located between the adjacent solid light sources 3 in the display unit 2 as a region B surrounded by a broken line, but this second embodiment. FIG. 4 shows an enlarged cross-sectional view of the main part of the region B, and the shape of the protrusion 51 of the housing case 5 and the shape of the notch 41 of the substrate 4 will be described in more detail. 4 corresponds to a cross-sectional view taken along the line C-C in FIG.
図４（ａ）に、ハウジングケース５の外周壁５ｂ内側の突起部５１の断面形状を示す。突起部５１の突出量は、二つの固体光源３間の中心となる位置に近づくにつれて徐々に大きくなるように形成される。そして、突起部５１の突出形状は、例えば、三角形状と円弧形状を組み合わせた形状であり、その三角形の角部や外周壁５ｂとの接続部の表面は緩やかな曲線形状（滑らかなカーブ）となるように形成されている。
突起部５１の表面を滑らかな形状とすることにより、外周壁５ｂの肉厚が従来のものより薄くなった場合でも、ハウジングケース５の成形型となる金型成形の段階や、その金型に樹脂充填してハウジングケース５を樹脂成形する段階において、充填する樹脂や金属の流動性を良くすることができ、樹脂成形や金属成形が容易となる。
なお、基板４の切り欠き部４１の形状は、ハウジングケース５の突起部５１に応じた形状であり、突起部５１と同様の三角形状と円弧形状を組み合わせた形に形成され、その三角形の角部や基板４の外周端部との接続部は、緩やかな曲線形状に形成される。
FIG. 4A shows a cross-sectional shape of the protruding portion 51 inside the outer peripheral wall 5 b of the housing case 5. The protrusion amount of the protrusion 51 is formed so as to gradually increase as it approaches the center position between the two solid light sources 3. And the protrusion shape of the projection part 51 is a shape which combined triangle shape and circular arc shape, for example, and the surface of the connection part with the corner | angular part of the triangle or the outer peripheral wall 5b is a gentle curve shape (smooth curve). It is formed to become.
By making the surface of the projection 51 smooth, even when the outer peripheral wall 5b is thinner than the conventional one, the mold forming stage of the housing case 5 and the mold In the step of resin-molding and housing case 5 to be resin-molded, the fluidity of the resin or metal to be filled can be improved, and resin molding or metal molding becomes easy.
The shape of the notch 41 of the substrate 4 is a shape corresponding to the protrusion 51 of the housing case 5 and is formed in a combination of a triangular shape and an arc shape similar to the protrusion 51, and the corner of the triangle The connection part with the outer peripheral end of the part and the substrate 4 is formed in a gentle curved shape.
次に、ハウジングケース５の外周壁５ｂに形成する別の形状の突起部５２を、図４（ｂ）を用いて説明する。この図４（ｂ）に示すように、例えば、Ｃ−Ｃ断面が三角形状となるような突起部５２を形成し、基板４の外周部に、突起部５２に対応した三角形状の切り欠き部４２を形成することも可能である。 Next, another shape of the protrusion 52 formed on the outer peripheral wall 5b of the housing case 5 will be described with reference to FIG. As shown in FIG. 4B, for example, a protrusion 52 having a triangular C-C cross section is formed, and a triangular notch corresponding to the protrusion 52 is formed on the outer periphery of the substrate 4. 42 can also be formed.
同様に、図４（ｃ）に示すように、円弧形状の突起部５３と、円弧形状の切り欠き部４３を備えた表示ユニット２を形成することもできる。
ハウジングケース５の外周壁５ｂの突起形状は、上記以外の形状とすることも可能であり、例えば、台形、正方形、長方形などの四角形状や、他の多角形の形状することもでき、これによって、ハウジングケース５の外周壁５ｂの強度を確保しつつ、固体光源３のピッチを表示ユニット２間にも適応できる高精細な映像表示装置１を得ることが可能である。
Similarly, as shown in FIG. 4C, the display unit 2 including the arc-shaped protrusion 53 and the arc-shaped notch 43 can be formed.
The protrusion shape of the outer peripheral wall 5b of the housing case 5 can be a shape other than those described above, for example, a trapezoidal shape, a square shape, a rectangular shape such as a rectangle, or another polygonal shape. In addition, it is possible to obtain a high-definition video display device 1 that can adapt the pitch of the solid light sources 3 between the display units 2 while ensuring the strength of the outer peripheral wall 5 b of the housing case 5.
さらに、一枚の表示ユニット２に対し、ハウジングケース５の外周壁５ｂに異なる形状の突起部を組み合わせて配置形成することも可能であることは言うまでもない。異なる形状の突起部をハウジングケース５の外周壁５ｂに選択的に形成することによって、ハウジングケース５に対する基板４の位置決め効果を持たせることが可能である。 Furthermore, it goes without saying that it is also possible to arrange and form protrusions having different shapes on the outer peripheral wall 5b of the housing case 5 for one display unit 2. By selectively forming the protrusions having different shapes on the outer peripheral wall 5 b of the housing case 5, it is possible to have a positioning effect of the substrate 4 with respect to the housing case 5.
なお、本発明は、その発明の範囲内において、各実施の形態を自由に組み合わせたり、各実施の形態を適宜、変形、省略することが可能である。 It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
