Description

【0001】
【発明の属する技術分野】
本発明は、例えば車両の計器装置に用いられ、立体感を高めた表示部を備えた表示板に関するものである。
【0002】
【従来の技術】
従来、自動車などの計器装置に用いられる表示板において、目盛や数字などの表示部を立体的に表現するものとして、例えば、特開平5−26697号公報がある。これは基板1の表面に目盛,数字などの表画像部2を形成し、基板1の裏面に陰画像部3を形成したものである。この様に形成することで、基板1の厚みにより目盛,数字などが立体的に見えるというものである。
【0003】
【発明が解決しようとする課題】
しかしながら、前記公報に記載された表示板は、基板1の板厚が薄くなる程立体感が乏しくなって平面的な表示となってしまうということがあった。
【0004】
本発明はこの様な点に鑑みなされたもので、立体感を高めた表示部を備えた表示板を提供することを目的とする。
【0005】
【課題を解決するための手段】
本発明は前記課題を解決するため、光透過性の基板と、この基板の表面側に形成した凸部からなる表示部と、この表示部に対応した前記基板の裏面側に設けた表示層と、前記表示部を除いた前記基板の表面側に設けた地色層と、前記表示部周囲の前記基板に遮光層を設けることによって形成され、前記基板の背後からの光源の発光により前記表示部の周囲が異なる明度で透過する透過部とを備えたものである。
【0008】
また、前記透過部は前記基板に透過性着色層を段階的に重ねて設けることによって前記表示部側が明であり、外側に向かって暗となるように形成したものである。
【0009】
また、前記凸部は前記基板に前記各層を設けた後にエンボス加工されたものである。
【0011】
【発明の実施の形態】
本発明の表示板を適用した車両の計器装置を実施形態として説明する。図1は速度計1と回転計2を備えた計器装置の正面図を示す。図2は図1におけるA−A断面であり、図3は回転計2に用いられる表示板の部分詳細断面図である。
【0012】
計器装置は、硬質な回路基板3と、この回路基板3の裏面側に回路基板3と導通状態で装着され、回路基板3を貫通して前方に延びる回動軸4を有する計器本体5と、回動軸4の先端側に固着された指示部6を有する指針7と、この指針7の後方に配置され指示部6の動作に対応する目盛,数字などの表示部8を設けた表示板9と、回路基板3上に実装され指針7や表示板9を背後から照明する光源としての発光ダイオード10,10Aと、表示板9の背後に配置された導光板11と、この導光板11の背後であって導光板11と回路基板3との間に配置された保持部材12と、回路基板3の裏面側を覆うカバー13と、表示板9の前方側に配置され表示板9の可視領域を定める開口部14を有する覆い部材15と、指針7や表示板9などの前方側を覆う無色透明な透視板16を備えている。
【0013】
指針7は無色透明な合成樹脂からなる指示部6と、指針軸17と、指示部6の基部周囲(指針軸17の上方)を覆う遮光部材としての黒色の指針キャップ18を備えている。指示部6の裏面には赤色の箔19がホットスタンプされている。この指針7は指針軸17を計器本体5の回動軸4の先端側に圧入することによって計器本体5に固着されている。指針7の指示部6は赤色で視認されるが、回路基板3上に実装された発光ダイオード10が発光した際も、指示部6の裏面に設けた赤色の箔19に発光ダイオード10から導かれた光が反射して赤色で視認されるようになっている。
【0014】
表示板9には、前述した如く、図1に示す様に指示部6の指示対象となる例えば車両のエンジン回転数を現す目盛,数字などの表示部8が設けてある(速度計の表示部は記載を省略する)。この表示部8はそれぞれ太目盛表示部8A,細目盛表示部8B,数字表示部8Cからなり、本実施形態の場合、太目盛表示部8Aは凸部20としてある。
【0015】
回転計2用の表示板9の断面を図3に示す。表示板9には、光透過性である無色透明な基板21の表面側に凸部20からなる太目盛表示部8Aを除いてクリーム色の地色層22と、数字表示部8Cとなる黒色の数字表示層23と、凸部20の際に縁取り部24となる黒色の遮光層25とが印刷形成されている。また、図示しないが細目盛表示部8Bに対応する基板21の表面側には黒色の半透過層が設けてある。また、太目盛表示部8Aを除いた基板21の表面側、すなわち、細目盛表示部8B,数字表示部8C,地色層22上には透明艶消し層26が設けてある。なお、縁取り部24となる黒色の遮光層25は太目盛表示部8Aのコントラストを高めるために設けたものであり、太目盛表示部8Aの色調と周囲(地色層22)の色調との兼ね合いを考慮して、必要に応じて設ければよい。
【0016】
太目盛表示部8Aに対応する基板21の裏面側には、金属調であるシルバーやゴールドなどの表示層27と、この表示層27が透過するのを防ぐための黒色の遮光層25Aが設けてある。また、表示板9には基板21の背後から光源としての例えば発光ダイオード10Aを発光させた際に、太目盛表示部8Aの周囲が透過する透過部28が設けてある。本実施形態においては、太目盛表示部8Aに対して片側約2mmの隙間を有して例えば黒色の遮光層25Bを設けることによって透過部28が形成されるものである。この透過部28となる基板21の裏面側に例えば白色の透過性着色層29を段階的に3層設ける。すなわち、1層を透過部28に対応する全面に設け、2層目を太目盛表示部8A側を僅かに除いた状態で設け、3層目は太目盛表示部8Aから更に離した周囲のみに設ける。この様に形成したことにより、透過部28は異なる明度で透過するようになる。つまり、平面方向に従って明度が異なる(透過輝度が変化する)。
【0017】
同様に、数字表示部8Cの周囲にも透過部28Aが設けてある。この透過部28Aも太目盛表示部8A用の透過部28と同様に、黒色の遮光層25Bを設けることによって形成される。そして、この透過部28Aにも段階的に3層からなる例えば白色の透過性着色層29が設けてある。なお、透過部28,28Aを形成するための黒色の遮光層25Bは太目盛表示部8Aおよび数字表示部8Cの周囲に透過部28,28Aを形成するためのものであるから、基板21の裏面に直に設けても良いし、白色の透過性着色層29を設けた後でも良く、あるいは基板21の表面側に設けても良い。また、白色の透過性着色層29も基板21の表面側に設けても良い。
【0018】
太目盛表示部8Aである凸部20は基板21に各層を設けた後、エンボス加工したものである。凸部20の形成は真空成形あるいは圧空成形でも良いが、真空成形や圧空成形では太目盛表示部8A(凸部20)にシャープ感が無く丸みを帯びた状態となって高級感に欠けてしまう。さらに成形コストも高くなるため、エンボス加工の方が良い。板厚の薄い基板をエンボス加工することにより、車両の計器装置に用いられる表示板のように比較的細かい表示部であっても、シャープ感が出せ、より立体的な表示部となる。
【0019】
保持部材12は遮光性のある白色の合成樹脂からなり、回動軸4周囲の指針7照明用の発光ダイオード10と表示板9を照明する発光ダイオード10Aとの間に立設した筒状部30と、この筒状部30の周囲に設けられ、発光ダイオード10Aからの光を周囲に反射する第1の反射部31と、発光ダイオード10A周辺から筒状部30を取り巻くように表示板9の周囲側に向かって傾斜して形成された第2の反射部32と、導光板11あるいは表示板9が載置される前面部33を備えている。この様に、保持部材12は導光板11および表示板9を保持するとともに、反射部材としての役目も果たしている。
【0020】
導光板11は光透過性の合成樹脂からなる。導光板11は前述したように保持部材12の前面部33に載置され、その上に表示板9が載置されるようになっている。従って、例えば接着剤や両面テープを用いて導光板11に表示板9を固着すれば、本実施形態のように板厚の薄い表示板9を用いたとしても表示板9がばたついたり変形するようなことは無い。また、発光ダイオード10Aから直接、あるいは保持部材12の第2の反射部32に反射して表示板9の裏面側に向かったそれぞれの光が導光板11で拡散されて、均一な表示板照明ができる。さらに、導光板11にシボなどの光拡散処理や網点印刷などの調光用処理を施すことによって、より均一な照明が可能となる。
【0021】
この様に、太目盛表示部8Aがシルバーやゴールドなどの金属調の凸部20からなるため、太目盛表示部8Aが立体的であり、かつ、高級感のある表示板9となる。また、太目盛表示部8A以外に透明艶消し層26が設けてあるため、金属調の太目盛表示部8Aのみが光沢状態となり、太目盛表示部8Aがより明瞭に視認される。
【0022】
また、夜間あるいは周囲が暗い時、例えば緑色で発光する発光ダイオード10Aを点灯させると、発光ダイオード10Aからの光は直接、あるいは第1の反射部31に反射した後第2の反射部32で反射してそれぞれ導光板11の裏面側に向かう。そして、導光板11を透過した光は表示板9の裏面側を照射する。すると、昼間時にはクリーム色の地に金属調で視認されていた太目盛表示部8Aと太目盛表示部8A周囲の透過部28を除いた地色層22とが暗く(黒く)なり、太目盛表示部8A周囲の透過部28が明度の異なる緑色で透過する。
【0023】
この際、透過部28は段階的に設けた白色の透過性着色層29によって太目盛表示部8A側が淡い緑色で透過表示し、外側に向かって徐々に緑色で透過表示する。すなわち、明から暗へと徐々に変化して透過する。これは太目盛表示部8A側の透過率が高く、外側の透過率が低いためである。従って、板厚の薄い表示板9であっても太目盛表示部8Aと背景(透過された透過性着色層)との間に奥行き感が与えられ、太目盛表示部8Aが少し浮いた状態で視認されるとともに、斬新な表示が可能となる。なお、発光ダイオード10Aが白色の発光色の場合は、透過性着色層29を例えば緑色とするようにしても良い。
【0024】
同様に、昼間時にはクリーム色の地に黒色で視認されていた数字表示部8Cと数字表示部8C周囲の透過部28Aを除いた地色層22とが暗く(黒く)なり、数字表示部8C周囲の透過部28Aが明度の異なる緑色で透過する。この透過部28Aは太目盛表示部8A箇所と同様に数字表示部8C側が淡い緑色で透過表示し、外側に向かって徐々に緑色で透過表示する。すなわち、明から暗へと徐々に変化して透過する。そして、太目盛表示部8Aと同様に数字表示部8Cが少し浮いた状態で視認されるとともに、斬新な表示を可能とする。
【0025】
なお、本実施形態においては、白色の透過性着色層29を段階的に3層設けたが、3層に限定するものではなく、透過性着色層29の色調も任意である。また、3層を異なる色とすることによって、透過部28,28Aの明るさをリング状で変化させることも出来る。また、透過性着色層29を網点状として、表示部側が粗で外側が密となるように設けることによって、明から暗へと徐々に変化する領域(透過部28,28A)を形成し、この領域で囲まれた表示部に奥行き感を持たせるようにしても良い。
【0026】
また、表示層27の裏側に黒色の遮光層25Aを設けたが、設けなくとも良い。但し、遮光層25Aを設けることによって、夜間時などに発光ダイオード10Aが点灯した際に、太目盛表示部8Aの周囲が透過するため、太目盛表示部8Aを不透過とした方が視認性が良い。また、凸部20からなる表示部を太目盛表示部8Aのみとしたが、細目盛表示部8B,数字表示部8Cの一方あるいは両方に適用しても良い。
【0027】

DETAILED DESCRIPTION OF THE INVENTION
A vehicle instrument device to which the display board of the present invention is applied will be described as an embodiment. FIG. 1 shows a front view of an instrument device provided with a speedometer 1 and a tachometer 2. 2 is a cross-sectional view taken along the line AA in FIG. 1, and FIG. 3 is a partial detailed cross-sectional view of a display panel used in the tachometer 2.
[0012]
The instrument device includes a rigid circuit board 3, an instrument body 5 that is mounted on the back side of the circuit board 3 in a conductive state with the circuit board 3 and has a pivot shaft 4 that extends forward through the circuit board 3, A display plate 9 provided with a pointer 7 having an indicator 6 fixed to the distal end side of the rotating shaft 4 and a display unit 8 arranged behind the pointer 7 and corresponding to the operation of the indicator 6 such as scales and numerals. The light emitting diodes 10 and 10A that are mounted on the circuit board 3 as light sources for illuminating the pointer 7 and the display plate 9 from behind, the light guide plate 11 disposed behind the display plate 9, and the back of the light guide plate 11 The holding member 12 disposed between the light guide plate 11 and the circuit board 3, the cover 13 covering the back side of the circuit board 3, and the visible region of the display board 9 disposed on the front side of the display board 9. A cover member 15 having an opening 14 to be defined, a pointer 7 and a display board 9 And a colorless transparent perspective plate 16 covering the rectangular side.
[0013]
The pointer 7 includes a pointing portion 6 made of a colorless and transparent synthetic resin, a pointer shaft 17, and a black pointer cap 18 as a light shielding member that covers the periphery of the base of the pointing portion 6 (above the pointer shaft 17). A red foil 19 is hot stamped on the back surface of the instruction unit 6. The pointer 7 is fixed to the meter body 5 by press-fitting the pointer shaft 17 into the distal end side of the rotating shaft 4 of the meter body 5. The indicator portion 6 of the pointer 7 is visually recognized in red. However, when the light emitting diode 10 mounted on the circuit board 3 emits light, it is guided from the light emitting diode 10 to the red foil 19 provided on the back surface of the indicator portion 6. The reflected light is reflected in red.
[0014]
As shown in FIG. 1, the display board 9 is provided with a display unit 8 such as a scale or a number indicating the engine speed of the vehicle to be instructed by the instruction unit 6 as shown in FIG. Is omitted). Each of the display sections 8 includes a thick scale display section 8A, a fine scale display section 8B, and a number display section 8C. In this embodiment, the thick scale display section 8A is a convex section 20.
[0015]
A cross section of the display board 9 for the tachometer 2 is shown in FIG. The display board 9 has a cream-colored ground color layer 22 on the surface side of the transparent and transparent substrate 21 that is light transmissive, except for the thick scale display portion 8A formed of the convex portions 20, and the black color that becomes the number display portion 8C. A number display layer 23 and a black light-shielding layer 25 that becomes an edge portion 24 at the time of the convex portion 20 are printed. Although not shown, a black translucent layer is provided on the surface side of the substrate 21 corresponding to the fine scale display portion 8B. A transparent matte layer 26 is provided on the surface side of the substrate 21 excluding the thick scale display portion 8A, that is, on the fine scale display portion 8B, the numeric display portion 8C, and the ground color layer 22. Note that the black light shielding layer 25 serving as the rim portion 24 is provided to increase the contrast of the thick scale display portion 8A, and the balance between the color tone of the thick scale display portion 8A and the color tone of the surrounding (ground color layer 22). May be provided as necessary.
[0016]
On the back surface side of the substrate 21 corresponding to the thick scale display portion 8A, there is provided a display layer 27 such as silver or gold which is metallic, and a black light shielding layer 25A for preventing the display layer 27 from being transmitted. is there. Further, the display plate 9 is provided with a transmission portion 28 through which the periphery of the thick scale display portion 8A transmits when, for example, the light emitting diode 10A as a light source emits light from behind the substrate 21. In the present embodiment, the transmission portion 28 is formed by providing, for example, a black light shielding layer 25B with a gap of about 2 mm on one side with respect to the thick scale display portion 8A. For example, three layers of, for example, a white transmissive colored layer 29 are provided in a stepwise manner on the back side of the substrate 21 to be the transmissive portion 28. That is, the first layer is provided on the entire surface corresponding to the transmission portion 28, the second layer is provided with the thick scale display portion 8A slightly removed, and the third layer is provided only around the periphery of the thick scale display portion 8A. Provide. By forming in this way, the transmissive part 28 is transmitted with different brightness. That is, the brightness varies according to the planar direction (transmission luminance changes).
[0017]
Similarly, a transmission portion 28A is also provided around the number display portion 8C. This transmissive portion 28A is also formed by providing a black light shielding layer 25B, similarly to the transmissive portion 28 for the thick scale display portion 8A. The transmitting portion 28A is also provided with, for example, a white transparent colored layer 29 composed of three layers step by step. The black light shielding layer 25B for forming the transmissive portions 28 and 28A is for forming the transmissive portions 28 and 28A around the thick scale display portion 8A and the numeric display portion 8C. It may be provided directly on the surface of the substrate 21 or after the white transparent colored layer 29 is provided. A white transparent colored layer 29 may also be provided on the surface side of the substrate 21.
[0018]
The convex portion 20 which is the thick scale display portion 8A is obtained by embossing after providing each layer on the substrate 21. The convex portion 20 may be formed by vacuum forming or pressure forming. However, in the vacuum forming or pressure forming, the thick scale display portion 8A (the convex portion 20) is not sharp but rounded and lacks a high-class feeling. . Furthermore, since the molding cost increases, embossing is better. By embossing a thin substrate, even a relatively fine display portion such as a display plate used in a vehicle instrument device can provide a sharp feeling and become a three-dimensional display portion.
[0019]
The holding member 12 is made of a white synthetic resin having a light shielding property, and a cylindrical portion 30 is provided between the light emitting diode 10 for illuminating the pointer 7 around the rotation shaft 4 and the light emitting diode 10A for illuminating the display board 9. A first reflecting portion 31 provided around the cylindrical portion 30 to reflect the light from the light emitting diode 10A to the periphery, and the periphery of the display plate 9 so as to surround the cylindrical portion 30 from the periphery of the light emitting diode 10A. A second reflecting portion 32 that is inclined toward the side and a front surface portion 33 on which the light guide plate 11 or the display plate 9 is placed are provided. Thus, the holding member 12 holds the light guide plate 11 and the display plate 9 and also serves as a reflecting member.
[0020]
The light guide plate 11 is made of a light transmissive synthetic resin. As described above, the light guide plate 11 is placed on the front surface portion 33 of the holding member 12, and the display plate 9 is placed thereon. Therefore, if the display plate 9 is fixed to the light guide plate 11 using, for example, an adhesive or a double-sided tape, the display plate 9 flutters or deforms even when the thin display plate 9 is used as in this embodiment. There is nothing to do. Further, each light reflected from the light emitting diode 10 </ b> A directly or to the second reflecting portion 32 of the holding member 12 toward the rear surface side of the display plate 9 is diffused by the light guide plate 11, and uniform display plate illumination is achieved. it can. Further, by applying light diffusion processing such as embossing and light control processing such as halftone printing to the light guide plate 11, more uniform illumination is possible.
[0021]
In this way, since the thick scale display portion 8A is composed of the metallic convex portions 20 such as silver and gold, the thick scale display portion 8A is a three-dimensional and high-quality display board 9. Further, since the transparent matte layer 26 is provided in addition to the thick scale display portion 8A, only the metallic thick scale display portion 8A is in a glossy state, and the thick scale display portion 8A is more clearly visible.
[0022]
Further, when the light emitting diode 10A that emits green light is turned on at night or in the dark, for example, the light from the light emitting diode 10A is reflected directly or reflected by the first reflecting portion 31 and then reflected by the second reflecting portion 32. Then, each goes to the back side of the light guide plate 11. And the light which permeate | transmitted the light-guide plate 11 irradiates the back surface side of the display board 9. FIG. Then, during the daytime, the thick scale display portion 8A that has been visually recognized in a metallic color on the cream-colored ground and the ground color layer 22 excluding the transmission portion 28 around the thick scale display portion 8A become dark (black), and the thick scale display. The transmissive part 28 around the part 8A transmits in green having different brightness.
[0023]
At this time, the transmissive portion 28 is transmissively displayed in light green on the thick scale display portion 8A side by the white transmissive colored layer 29 provided in stages, and gradually transmissively displayed in green toward the outside. That is, the light gradually changes from light to dark and transmits. This is because the transmittance on the thick scale display portion 8A side is high and the transmittance on the outside is low. Therefore, even in the thin display board 9, a sense of depth is given between the thick scale display portion 8A and the background (transmitted transparent colored layer), and the thick scale display portion 8A is slightly lifted. In addition to being visually recognized, a novel display becomes possible. When the light emitting diode 10A has a white emission color, the transmissive colored layer 29 may be green, for example.
[0024]
Similarly, the number display portion 8C, which was visually recognized in black on a cream-colored ground during the daytime, and the ground color layer 22 excluding the transmission portion 28A around the number display portion 8C become dark (black), and the number display portion 8C surroundings The transmission part 28A of the light is transmitted in green with different brightness. As with the thick scale display portion 8A, the transmissive portion 28A is transmissively displayed in light green on the numeric display portion 8C side, and gradually transmissively displayed in green toward the outside. That is, the light gradually changes from light to dark and transmits. Then, like the thick scale display portion 8A, the numeric display portion 8C is visually recognized in a slightly floating state, and a novel display is enabled.
[0025]
In the present embodiment, three white transparent colored layers 29 are provided stepwise, but the number is not limited to three, and the color tone of the transparent colored layer 29 is also arbitrary. Moreover, the brightness of the transmissive portions 28 and 28A can be changed in a ring shape by making the three layers have different colors. In addition, by forming the transparent colored layer 29 as a halftone dot so that the display side is rough and the outside is dense, a region (transmission portions 28 and 28A) that gradually changes from light to dark is formed. You may make it give a feeling of depth to the display part enclosed by this area | region.
[0026]
Further, although the black light shielding layer 25A is provided on the back side of the display layer 27, it is not necessary to provide it. However, by providing the light shielding layer 25A, when the light emitting diode 10A is turned on at night or the like, the periphery of the thick scale display portion 8A is transmitted. Therefore, the visibility is better when the thick scale display portion 8A is opaque. good.
