Description

ディスプレイdisplay
本発明は、野外ステージや建造物等に設置されるディスプレイに関する。 The present invention relates to a display installed on an outdoor stage or a building.
ディスプレイには、表示ドットに発光ダイオードを用いた、屋外でも使用可能なものがあり、例えば、特許文献１、特許文献２にその具体例が記載されている。
特許文献１では、ディスプレイの表面に位置する前板部材の表面に黒色塗装がなされ、発光ダイオード（ＬＥＤ）群が黒塗りの枠で仕切られているので、コントラストの高い画像を表示できる。また、特許文献２記載の技術では、各々がモールドレンズを有する複数の発光ダイオードを所望の形状に配置し、各発光ダイオード間に予め着色剤を含む合成繊維を植毛しているので、発光ダイオード間から視認者側に反射する光を低減し、ディスプレイを見え易くしている。 Some displays use light emitting diodes as display dots and can be used outdoors. For example, Patent Documents 1 and 2 describe specific examples.
In Patent Document 1, since the surface of the front plate member positioned on the surface of the display is painted black and the light emitting diode (LED) group is partitioned by a black frame, an image with high contrast can be displayed. In the technique described in Patent Document 2, a plurality of light emitting diodes each having a molded lens are arranged in a desired shape, and synthetic fibers containing a colorant are previously planted between the light emitting diodes. The light reflected from the viewer to the viewer side is reduced to make the display easier to see.

特許文献２記載の技術は、発光ダイオードの隙間を基盤に植設したフロック（短繊維）で埋めているので、特許文献１記載の技術より反射光は少なくなるが、発光ダイオードにモールドレンズを有するものを使用しているので、ディスプレイに表示された画像の見える範囲が狭く、交通信号器として使用する場合は優れているとしても、ディスプレイとして使用すると見える角度が限定され、視野範囲が狭いという問題があった。 However, the technique of Patent Document 1 has a problem that when light such as sunlight is reflected on the surface of the front plate member, an image displayed on the display becomes unclear.
Since the technology described in Patent Document 2 is filled with flocks (short fibers) planted on the basis of the gaps of the light emitting diodes, the reflected light is less than the technology described in Patent Document 1, but the light emitting diode has a molded lens. Because it uses a thing, the visible range of the image displayed on the display is narrow, even if it is excellent when used as a traffic signal, the angle that can be seen as a display is limited, and the field of view is narrow was there.
特許文献２の技術では、植毛された短繊維は予め顔料で着色されているので、仮に顔料に黒色顔料が使用されていたとしても、短繊維の滑らかな表面から多少の反射があり、例えば、太陽光が射した場合には、ディスプレイ自体が見にくくなるという問題があった。
更には、特許文献１、２の技術において、隣り合う発光ダイオードの間の全部の領域が盲状態となっているので、ディスプレイの後ろ側にある物は全く視認できず、野外にこのディスプレイを設けた場合は風の圧力を直に受けるので、強固にディスプレイを設置する必要があった。 In the technique of Patent Document 2, since the implanted short fibers are colored with a pigment in advance, even if a black pigment is used as the pigment, there is some reflection from the smooth surface of the short fibers, for example, When sunlight shines, there is a problem that the display itself is difficult to see.

バックパネル１２は、正面視して横長の矩形であり、バックパネル１２の前面全体には、多数の発光ダイオード１１が縦横に等ピッチで配置されている。発光ダイオード１１の配置ピッチは、本実施例において１５．６２５ｍｍであるが、この配置ピッチに限定されず他の配置ピッチ（例えば、９～３０ｍｍピッチ）にしてもよい。 As shown in FIGS. 1A and 1B, the display 10 includes a back panel 12, a plurality of light emitting diodes 11 provided on the surface of the back panel 12, and a controller that transmits an output signal to each light emitting diode 11. 13.
The back panel 12 has a horizontally long rectangle when viewed from the front, and a large number of light emitting diodes 11 are arranged at equal pitches vertically and horizontally on the entire front surface of the back panel 12. The arrangement pitch of the light emitting diodes 11 is 15.625 mm in this embodiment, but is not limited to this arrangement pitch and may be other arrangement pitches (for example, 9 to 30 mm pitch).
バックパネル１２には、複数の縦長のスリット１４が形成され、発光ダイオード１１の縦列の各間には、上下に２つのスリット１４が間隔を有して配置されている。バックパネル１２は、このスリット１４によって軽量化が図られ、更に、前後に風の通過路を形成するので、バックパネル１２に生じる風圧の大きさを抑えることができる。 A plurality of vertically long slits 14 are formed in the back panel 12, and two slits 14 are vertically arranged between the columns of the light emitting diodes 11. The back panel 12 is reduced in weight by the slits 14, and further, wind passages are formed in the front and rear, so that the magnitude of the wind pressure generated in the back panel 12 can be suppressed.
バックパネル１２は、同一平面上に密接して並べられた複数のパネルユニット１５からなり、各パネルユニット１５の前面には、複数の発光ダイオード１１が露出して設けられている。なお、本実施例では、バックパネル１２は、縦２列、横１６列で合計３２個のパネルユニット１５から形成されているが、３２個より多い、あるいは少ないパネルユニット１５を用いることもでき、パネルユニット１５の数によって、バックパネルの大きさを調整可能である。また、バックパネル１２の裏面には、図示しない固定フレームが設けられ、各パネルユニット１５は周知のねじ部材によって、固定フレームに取り付けられている。 The back panel 12 includes a plurality of panel units 15 closely arranged on the same plane, and a plurality of light emitting diodes 11 are exposed on the front surface of each panel unit 15. In the present embodiment, the back panel 12 is formed of a total of 32 panel units 15 in 2 rows and 16 rows, but more or less than 32 panel units 15 can be used. The size of the back panel can be adjusted by the number of panel units 15. Further, a fixed frame (not shown) is provided on the back surface of the back panel 12, and each panel unit 15 is attached to the fixed frame by a known screw member.
図３（Ａ）、（Ｂ）に示すように、パネルユニット１５は、複数の発光ダイオード１１が設けられたＬＥＤ基板１６と、ＬＥＤ基板１６の前面に密接配置された表面パネル材１７を有している。
図２（Ａ）、（Ｂ）に示すように、表面パネル材１７とＬＥＤ基板１６は、正面視して略同一の形状を有し、ＬＥＤ基板１６の前面は、発光ダイオード１１の配置箇所（即ち、発光ダイオードの露出領域）等を除いた部分が、表面パネル材１７によって覆われる。 As shown in FIGS. 3A and 3B, the panel unit 15 includes an LED substrate 16 provided with a plurality of light emitting diodes 11, and a surface panel material 17 disposed in close contact with the front surface of the LED substrate 16. ing.
As shown in FIGS. 2A and 2B, the front panel member 17 and the LED substrate 16 have substantially the same shape when viewed from the front, and the front surface of the LED substrate 16 is disposed at the place where the light emitting diodes 11 are disposed ( That is, the portion excluding the exposed region of the light emitting diode) is covered with the surface panel material 17.
表面パネル材１７の全体には、正面視して正方形の複数の貫通孔１８が縦横に等間隔で形成されており、表面パネル材１７とＬＥＤ基板１６が固定された状態で、発光ダイオード１１は、正面から貫通孔１８を介して視認可能である。発光ダイオード１１は、赤色ＬＥＤ素子、青色ＬＥＤ素子及び緑色ＬＥＤ素子を有するＳＭＤタイプ（即ち、表面実装型）のチップ（ＬＥＤチップ）であり、ディスプレイ１０は、映像をカラー表示することができる。ＳＭＤタイプの発光ダイオードは発光面が平面かつ正方形となって、しかも黒色となって反射光を減少させている。 The front panel member 17 has a plurality of square through holes 18 formed at equal intervals in the vertical and horizontal directions when viewed from the front, and the light emitting diode 11 is in a state where the front panel member 17 and the LED substrate 16 are fixed. It is visible from the front through the through hole 18. The light emitting diode 11 is an SMD type (that is, surface mount type) chip (LED chip) having a red LED element, a blue LED element, and a green LED element, and the display 10 can display an image in color. The SMD type light emitting diode has a light emitting surface that is flat and square, and has a black color to reduce reflected light.
表面パネル材１７は、正面から見て、そのアウトラインが矩形状となっている。
表面パネル材１７には、この実施例では平行配置された４本の帯板部１９が間隔を有して設けられ、各帯板部１９は表面パネル材１７の長尺方向に沿っている。隣り合う帯板部１９の間にはスリット２０が形成されている。なお、スリット２０の幅は帯板部１９の幅の０．３～１．７倍の範囲となっている。
帯板部１９の両端には、正面視して矩形の固定部２１、２２がそれぞれ連続して形成されている。固定部２１、２２には、それぞれ丸孔２３、２４が設けられ、丸孔２３、２４には、表面パネル材１７及びＬＥＤ基板１６を固定フレームに固定するためのねじ部材が挿通可能である。 The front panel member 17 has a rectangular outline when viewed from the front.
In this embodiment, four strips 19 arranged in parallel are provided at intervals on the surface panel member 17, and each strip 19 is along the longitudinal direction of the surface panel member 17. A slit 20 is formed between adjacent band plate portions 19. The width of the slit 20 is in the range of 0.3 to 1.7 times the width of the band plate portion 19.
At both ends of the band plate portion 19, rectangular fixing portions 21 and 22 are formed continuously in front view, respectively. The fixing portions 21 and 22 are provided with round holes 23 and 24, respectively, and screw members for fixing the surface panel member 17 and the LED substrate 16 to the fixing frame can be inserted into the round holes 23 and 24, respectively.
露出面が黒色の表面パネル材１７の前面全体には、ポリカーボネイト、ＡＢＳ樹脂、ナイロン等を植毛素材とする黒色の静電植毛加工（例えば、特許３８４８９７７号公報）がなされている。この静電植毛加工は、黒色の短繊維を植毛してもよいが、この実施例では、静電植毛を行った後、短繊維を所定長（例えば０．６ｍｍ）に切断し、しかる後に短繊維に黒色の着色加工（染色加工）を施している。表面パネル材１７の前面は、この静電植毛加工によって、光の反射が抑制された状態になっている。従って、ディスプレイ１０は、バックパネル１２に太陽光や照明等が照射されても、光の反射が抑制され、映像を鮮明に表示することができる。このように、表面パネル材１７の表面に静電植毛を行った後、黒色に染めると、光の波長によって多少異なるが、光の反射率は、０．６１～０．９７％の範囲であった。一方、黒色の表面パネル材のみでは、光の反射率は４．７７～５．３１％程度であり、静電植毛を行った方が格段に反射率が下がる。 A black electrostatic flocking process (for example, Japanese Patent No. 3848977) using a polycarbonate, ABS resin, nylon or the like as a flocking material is performed on the entire front surface of the surface panel member 17 having a black exposed surface. In this electrostatic flocking process, black short fibers may be flocked, but in this embodiment, after performing electrostatic flocking, the short fibers are cut into a predetermined length (for example, 0.6 mm) and then short. The fiber is subjected to black coloring (dyeing). The front surface of the surface panel member 17 is in a state in which reflection of light is suppressed by the electrostatic flocking process. Therefore, even if sunlight, illumination, etc. are irradiated to the back panel 12, the display 10 can suppress reflection of light and can display an image clearly. As described above, when electrostatic flocking is performed on the surface of the surface panel member 17 and then dyed black, the reflectance of light is in the range of 0.61 to 0.97%, although it varies slightly depending on the wavelength of light. It was. On the other hand, only the black surface panel material has a light reflectivity of about 4.77 to 5.31%, and the reflectivity decreases significantly when electrostatic flocking is performed.
図３（Ａ）、（Ｂ）に示すように、表面パネル材１７の前面は、貫通孔１８の周囲が貫通孔１８に向かって角度θ（本実施例では、０．５°＜θ＜５°）で下り傾斜している。貫通孔１８に配置されている発光ダイオード１１は、この貫通孔１８の周囲の傾斜面によって、視野角が広げられている。
また、表面パネル材１７は、貫通孔１８の周囲を貫通孔１８に向かって下り傾斜することによって、その他の傾斜していない部分にある程度の厚み（本実施例では、１～２ｍｍ）を確保している。ここで、表面パネル材に傾斜部を設けることなく、表面パネル材１７と同程度の発光ダイオード１１の視野角を確保しようとすると、表面パネル材の全体を表面パネル材１７の最も薄い部分、即ち貫通孔１８の外周部と同程度の厚みにする必要がある。この場合、表面パネル材は、強度を保つことができず、小さな衝撃等により、割れ等が発生する。 As shown in FIGS. 3A and 3B, the front surface of the surface panel member 17 has an angle θ around the through hole 18 toward the through hole 18 (in this embodiment, 0.5 ° <θ <5 It is inclined down at °). The light emitting diode 11 disposed in the through hole 18 has a wide viewing angle by an inclined surface around the through hole 18.
Further, the surface panel member 17 is inclined down toward the through hole 18 around the through hole 18 so that a certain amount of thickness (1 to 2 mm in this embodiment) is ensured in other non-inclined portions. ing. Here, if the viewing angle of the light-emitting diode 11 comparable to that of the surface panel material 17 is to be secured without providing an inclined portion in the surface panel material, the entire surface panel material is the thinnest portion of the surface panel material 17, that is, It is necessary to make the thickness about the same as the outer peripheral portion of the through hole 18. In this case, the surface panel material cannot maintain strength, and cracks or the like are generated due to a small impact or the like.
図２（Ｂ）に示すように、ＬＥＤ基板１６は、表面パネル材１７と同様に正面から見て、そのアウトラインが矩形となっており、間隔を有して平行配置された４本の帯板部１９ａを備えている。ＬＥＤ基板１６には、表面パネル材１７と同様に、隣り合う帯板部１９ａの間にスリット２０ａが形成されている。
ＬＥＤ基板１６と表面パネル材１７が密接配置された際、ＬＥＤ基板１６のスリット２０ａは、正面視して表面パネル材１７のスリット２０と同位置となり、バックパネル１２のスリット１４を形成する（図１（Ａ）参照）。
帯板部１９ａの両端には、矩形の固定部２１ａ、２２ａがそれぞれ連続して形成され、固定部２１ａ、２２ａには、表面パネル材１７の丸孔２３、２４に挿通されるねじ部材が貫通する丸孔２３ａ、２４ａがそれぞれ設けられている。 As shown in FIG. 2 (B), the LED board 16 has four outlines that are rectangular in outline when viewed from the front as in the case of the surface panel member 17, and are arranged in parallel at intervals. A portion 19a is provided. In the LED substrate 16, similarly to the surface panel material 17, a slit 20 a is formed between adjacent strip plate portions 19 a.
When the LED substrate 16 and the surface panel material 17 are closely arranged, the slit 20a of the LED substrate 16 is located at the same position as the slit 20 of the surface panel material 17 when viewed from the front, forming the slit 14 of the back panel 12 (FIG. 1 (A)).
Rectangular fixing portions 21a and 22a are respectively formed continuously at both ends of the band plate portion 19a, and screw members inserted into the round holes 23 and 24 of the surface panel material 17 penetrate the fixing portions 21a and 22a. Round holes 23a and 24a are provided respectively.
