表示装置Display device
　本発明は、乗り物に搭載される表示装置に関する。 The present invention relates to a display device mounted on a vehicle.
　乗り物に搭載される表示装置として、例えば、特許文献１には、表示部の前面に光硬化型接着剤を介して透光性カバーが固定された構造の表示装置が開示されている。この表示部は、平面状の前面に画像を表示するディスプレイ（以下、平面ディスプレイと言う。）から構成されている。 As a display device mounted on a vehicle, for example, Patent Document 1 discloses a display device having a structure in which a translucent cover is fixed to the front surface of a display unit via a photocurable adhesive. This display unit is composed of a display (hereinafter, referred to as a flat display) that displays an image on a flat front surface.
特開２０１５－１４８７１８号公報Japanese Unexamined Patent Publication No. 2015-148718
　車両等の乗り物においては搭乗者に様々な情報を表示すべく、複数の表示部を備える表示装置が提案されている。また、表示部を覆う透光性カバーは、例えば車両のインストルメントパネルのデザインに合わせて、曲面形状で形成されることがある。このような表示装置において、特許文献１に開示された技術を適用した場合、曲面形状の透光性カバーを複数の表示部の各々の前面に光硬化型接着剤で固定すればよい。しかし、複数の表示部に平面ディスプレイが含まれている場合、平面ディスプレイの前面と、曲面形状の透光性カバーとの間の空間が広くなるため、光硬化型接着剤が大量に必要となり、コストの増大に繋がる虞がある。 For vehicles such as vehicles, a display device having a plurality of display units has been proposed in order to display various information to passengers. Further, the translucent cover that covers the display unit may be formed in a curved surface shape, for example, according to the design of the instrument panel of the vehicle. When the technique disclosed in Patent Document 1 is applied to such a display device, a curved translucent cover may be fixed to the front surface of each of a plurality of display units with a photocurable adhesive. However, when a plurality of display units include a flat display, a large amount of photocurable adhesive is required because the space between the front surface of the flat display and the curved translucent cover becomes wide. It may lead to an increase in cost.
　一方、曲面形状の透光性カバーで平面ディスプレイを含む複数の表示部を覆う場合に何の対策も施さなければ、平面ディスプレイだけが曲面感を失い、表示装置における複数の表示部に一体感が感じられなくなる虞もある。 On the other hand, if no measures are taken when covering a plurality of display units including a flat display with a curved translucent cover, only the flat display loses the curved surface feeling, and the multiple display parts in the display device have a sense of unity. It may not be felt.
　本発明は、上記実情に鑑みてなされたものであり、光硬化型接着剤の使用量を低減し、又は使用せずに、一体感のある見栄えの表示装置を提供することを目的とする。 The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a display device having a sense of unity and appearance without using or reducing the amount of the photocurable adhesive used.
　上記目的を達成するため、本発明に係る表示装置は、
　乗り物に搭載される表示装置であって、
　隙間を空けて隣り合う第１表示部及び第２表示部と、
　前記第１表示部及び前記第２表示部の各々が表示する情報を視認可能とする透光領域を有し、前記第１表示部及び前記第２表示部を前面側から覆う板状部と、
　曲面形状を有し、前記板状部を前面側から覆う透光性カバーと、を備え、
　前記第１表示部は、平面状の前面に画像を表示するディスプレイからなり、
　前記第１表示部の前面と前記第２表示部の前面は、傾きと前後方向における位置との少なくともいずれかが異なり、
　前記板状部は、前記隙間を覆うとともに、前記第１表示部と前記第２表示部とを繋ぐように形成された曲面部を有する。 In order to achieve the above object, the display device according to the present invention is

　本発明によれば、光硬化型接着剤の使用量を低減し、又は使用せずに、一体感のある見栄えの表示装置を提供することができる。 According to the present invention, it is possible to provide a display device having a sense of unity and appearance without using or reducing the amount of the photocurable adhesive used.

　メータ表示部１１は、表示装置１００の左右方向における中央部に位置し、車速、エンジン回転数などの車両に関する計測量を表示する。メータ表示部１１は、例えば、正面視で矩形状をなすＴＦＴ（Thin Film Transistor）型の液晶ディスプレイ（ＬＣＤ：Liquid Crystal Display）から構成されている。液晶ディスプレイは、液晶パネル、液晶パネルを背後から照明するバックライト等を有して構成されている。バックライトは、例えば、ＬＥＤ（Light Emitting Diode）やＬＥＤが発した光を導く導光部材等から構成されている。メータ表示部１１は、平面状の前面１１ａに画像を表示する平面ディスプレイである。 The meter display unit 11 is located at the center of the display device 100 in the left-right direction, and displays measured quantities related to the vehicle such as vehicle speed and engine speed. The meter display unit 11 is composed of, for example, a TFT (Thin Film Transistor) type liquid crystal display (LCD: Liquid Crystal Display) having a rectangular shape when viewed from the front. The liquid crystal display is configured to include a liquid crystal panel, a backlight that illuminates the liquid crystal panel from behind, and the like. The backlight is composed of, for example, an LED (Light Emitting Diode), a light guide member that guides the light emitted by the LED, and the like. The meter display unit 11 is a flat display that displays an image on a flat front surface 11a.
　多機能表示部１２は、メータ表示部１１よりも車両の中心寄りに位置し、種々の情報を表示可能なＣＩＤ（Center Information Display）として構成されている。なお、本実施形態に係る表示装置１００は、左ハンドル車用のものであるため、表示装置１００の右側が車両の中心側となる。多機能表示部１２は、例えば、正面視で矩形状をなすＴＦＴ型の液晶ディスプレイから構成されている。例えば、多機能表示部１２の前面側には、図示しない静電容量式のセンサシートが設けられている。このセンサシートは、透光性カバー２０のうち前後方向において多機能表示部１２と対向する部分（後述の凸曲面部２２）の前面に対してユーザの手が触れることでなされるタッチ操作を検出可能に構成されている。多機能表示部１２は、このセンサシートで検出されたタッチ操作に応じて、カーナビゲーション情報、娯楽情報、バックモニタ情報などの各種情報を表示可能となっている。多機能表示部１２は、平面状の前面１２ａに画像を表示する平面ディスプレイである。なお、センサシートは、多機能表示部１２の前面１２ａや透光性カバー２０の背面に設けられていればよい。 The multifunction display unit 12 is located closer to the center of the vehicle than the meter display unit 11 and is configured as a CID (Center Information Display) capable of displaying various information. Since the display device 100 according to the present embodiment is for a left-hand steering wheel vehicle, the right side of the display device 100 is the center side of the vehicle. The multifunctional display unit 12 is composed of, for example, a TFT-type liquid crystal display having a rectangular shape when viewed from the front. For example, a capacitance type sensor sheet (not shown) is provided on the front side of the multifunction display unit 12. This sensor sheet detects a touch operation performed by the user's hand touching the front surface of a portion (convex curved surface portion 22 described later) facing the multifunction display unit 12 in the front-rear direction of the translucent cover 20. It is configured to be possible. The multifunctional display unit 12 can display various information such as car navigation information, entertainment information, and back monitor information in response to the touch operation detected by the sensor sheet. The multifunction display unit 12 is a flat display that displays an image on a flat front surface 12a. The sensor sheet may be provided on the front surface 12a of the multifunction display unit 12 or the back surface of the translucent cover 20.
　ミラー表示部１３は、メータ表示部１１よりも左側に位置し、サイドミラーの反射像を模した画像を表示する。具体的に、ミラー表示部１３は、図示しないサイドカメラにより撮影され、車両の左側後方の風景を示すサイドミラー画像を表示する。ミラー表示部１３は、例えば、正面視で矩形状をなすＴＦＴ型の液晶ディスプレイから構成されている。例えば、ミラー表示部１３の前面側には、図示しない静電容量式のセンサシートが設けられている。このセンサシートは、透光性カバー２０のうち前後方向においてミラー表示部１３と対向する部分（後述の凸曲面部２３）の前面に対してユーザの手が触れることでなされるタッチ操作を検出可能に構成されている。ミラー表示部１３は、このセンサシートで検出されたタッチ操作に応じて、撮影方向が調整されたサイドカメラが撮影した画像を表示可能となっている。ミラー表示部１３は、平面状の前面１３ａに画像を表示する平面ディスプレイである。なお、センサシートは、ミラー表示部１３の前面１３ａや透光性カバー２０の背面に設けられていればよい。 The mirror display unit 13 is located on the left side of the meter display unit 11 and displays an image imitating the reflected image of the side mirror. Specifically, the mirror display unit 13 displays a side mirror image taken by a side camera (not shown) and showing a landscape on the left rear side of the vehicle. The mirror display unit 13 is composed of, for example, a TFT-type liquid crystal display having a rectangular shape when viewed from the front. For example, a capacitance type sensor sheet (not shown) is provided on the front side of the mirror display unit 13. This sensor sheet can detect a touch operation performed by a user's hand touching the front surface of a portion (convex curved surface portion 23 described later) facing the mirror display portion 13 in the front-rear direction of the translucent cover 20. It is configured in. The mirror display unit 13 can display an image taken by the side camera whose shooting direction is adjusted in response to the touch operation detected by the sensor sheet. The mirror display unit 13 is a flat display that displays an image on a flat front surface 13a. The sensor sheet may be provided on the front surface 13a of the mirror display unit 13 or the back surface of the translucent cover 20.
　図２に示すように、メータ表示部１１の前面１１ａは、多機能表示部１２の前面１２ａ及びミラー表示部１３の前面１３ａよりも後方に位置する。また、多機能表示部１２の前面１２ａは、メータ表示部１１の前面１１ａに対して図２における反時計回りに傾いている。また、ミラー表示部１３の前面１３ａは、メータ表示部１１の前面１１ａに対して図２における時計回りに傾いている。また、これら複数の表示部は、左右方向において隣り合うもの同士が隙間を空けて配列されている。 As shown in FIG. 2, the front surface 11a of the meter display unit 11 is located behind the front surface 12a of the multifunction display unit 12 and the front surface 13a of the mirror display unit 13. Further, the front surface 12a of the multifunction display unit 12 is tilted counterclockwise in FIG. 2 with respect to the front surface 11a of the meter display unit 11. Further, the front surface 13a of the mirror display unit 13 is tilted clockwise in FIG. 2 with respect to the front surface 11a of the meter display unit 11. Further, in these plurality of display units, adjacent ones in the left-right direction are arranged with a gap.
　透光性カバー２０は、図２に示すように、複数の表示部を前面側から覆う透光性を有する板材である。透光性カバー２０は、例えば、表示装置１００が搭載される車両のインストルメンタルパネルのデザインに合わせて曲面形状を有して形成されている。透光性カバー２０は、曲面形状に形成された部分として、凹曲面部２１と、凸曲面部２２，２３を有する。凹曲面部２１は、メータ表示部１１と前後方向において対向し、後方に向かって凹む曲面形状を有している。凸曲面部２２は、多機能表示部１２と前後方向において対向し、前方に向かって凸となる曲面形状を有している。凸曲面部２３は、ミラー表示部１３と前後方向において対向し、前方に向かって凸となる曲面形状を有している。 As shown in FIG. 2, the translucent cover 20 is a plate material having translucency that covers a plurality of display units from the front side. The translucent cover 20 is formed, for example, having a curved surface shape in accordance with the design of the instrument panel of the vehicle on which the display device 100 is mounted. The translucent cover 20 has a concave curved surface portion 21 and convex curved surface portions 22, 23 as portions formed in a curved surface shape. The concave curved surface portion 21 has a curved surface shape that faces the meter display unit 11 in the front-rear direction and is recessed toward the rear. The convex curved surface portion 22 has a curved surface shape that faces the multifunction display unit 12 in the front-rear direction and becomes convex toward the front. The convex curved surface portion 23 has a curved surface shape that faces the mirror display portion 13 in the front-rear direction and becomes convex toward the front.
　板状部３０は、複数の表示部を前面側から覆うとともに、複数の表示部と透光性カバー２０との間に位置する板状の部分である。板状部３０と透光性カバー２０との間には、若干の隙間（エアギャップ）が形成されている。板状部３０は、図３に示すように、メータ表示部１１、多機能表示部１２及びミラー表示部１３の各々が表示する画像を視認可能とする透光領域３１，３２，３３を有する。 The plate-shaped portion 30 is a plate-shaped portion that covers the plurality of display portions from the front side and is located between the plurality of display portions and the translucent cover 20. A slight gap (air gap) is formed between the plate-shaped portion 30 and the translucent cover 20. As shown in FIG. 3, the plate-shaped portion 30 has translucent regions 31, 32, and 33 that make it possible to visually recognize the image displayed by each of the meter display unit 11, the multifunctional display unit 12, and the mirror display unit 13.
　具体的に、板状部３０は、図４に示すように、板材３０ａと遮光層３０ｂを有する。板材３０ａは、例えば、透光性を有する樹脂から形成された板状の部材である。 Specifically, as shown in FIG. 4, the plate-shaped portion 30 has a plate material 30a and a light-shielding layer 30b. The plate material 30a is, for example, a plate-shaped member formed of a translucent resin.
　ここで、前述の透光性カバー２０は、例えば、ポリカーボネート（ＰＣ）とアクリル（ＰＭＭＡ）の混合材料からスモーク色に形成されており、光の透過率が５０％程度に設定されている。また、板材３０ａは、例えば、ポリカーボネート（ＰＣ）からスモーク色に形成されており、光の透過率が５０％程度に設定されている。このようにして、表示装置１００の前方からの外光の侵入を制限することで、透光性カバー２０に加えて板状部３０を設けたことの違和感を低減することができ、表示装置１００の一体感を向上させることができる。なお、透光性カバー２０及び板材３０ａのそれぞれの光の透過率は任意であり、８０％や３０％等であってもよい。また、透光性カバー２０や板材３０ａの材料も任意である。例えば、透光性カバー２０は、スモーク色の無機ガラスから構成されてもよい。 Here, the above-mentioned translucent cover 20 is formed in a smoke color from, for example, a mixed material of polycarbonate (PC) and acrylic (PMMA), and the light transmittance is set to about 50%. Further, the plate material 30a is formed of, for example, polycarbonate (PC) in a smoke color, and the light transmittance is set to about 50%. By limiting the intrusion of external light from the front of the display device 100 in this way, it is possible to reduce the discomfort of providing the plate-shaped portion 30 in addition to the translucent cover 20, and the display device 100 can be used. The sense of unity can be improved. The light transmittance of the translucent cover 20 and the plate material 30a is arbitrary, and may be 80%, 30%, or the like. Further, the material of the translucent cover 20 and the plate material 30a is also arbitrary. For example, the translucent cover 20 may be made of smoke-colored inorganic glass.
　また、透光性カバー２０の前面及び背面の少なくともいずれかと、板材３０ａの前面及び背面の少なくともいずれかに低反射処理を施してもよい。低反射処理として、例えば、透光性カバー２０の前面と板材３０ａの背面にＡＲ（Anti-Reflection）処理を施し、透光性カバー２０の背面と板材３０ａの前面にモスアイ処理を施すことができる。なお、低反射処理は、ＡＧ（Anti-Glare）処理などであってもよい。低反射処理の方法としては、フィルム貼合、フィルムインサート成形（ＩＭＬ：Insert Molding Laminate）、スパッタリング等を用いることができる。このように反射を防止することで、透光性カバー２０に加えて板状部３０を設けたことの違和感を低減することができ、表示装置１００の一体感を向上させることができる。 Further, at least one of the front surface and the back surface of the translucent cover 20 and at least one of the front surface and the back surface of the plate material 30a may be subjected to a low reflection treatment. As the low reflection treatment, for example, AR (Anti-Reflection) treatment can be applied to the front surface of the translucent cover 20 and the back surface of the plate material 30a, and moth-eye treatment can be applied to the back surface of the translucent cover 20 and the front surface of the plate material 30a. .. The low reflection treatment may be an AG (Anti-Glare) treatment or the like. As a method of low reflection treatment, film bonding, film insert molding (IML: Insert Molding Laminate), sputtering and the like can be used. By preventing reflection in this way, it is possible to reduce the discomfort of providing the plate-shaped portion 30 in addition to the translucent cover 20, and it is possible to improve the sense of unity of the display device 100.
　遮光層３０ｂは、例えば、スクリーン印刷やパッド印刷により板材３０ａの背面に形成された黒色の印刷層からなる。板状部３０における透光領域３１，３２，３３の各々は、板材３０ａの遮光層３０ｂが設けられていない部分により形成される。なお、図４の拡大断面図では、メータ表示部１１に対応する透光領域３１及び多機能表示部１２に対応する透光領域３２について示したが、透光領域３３についても同様である。なお、遮光層３０ｂは、板材３０ａの前面と背面の少なくともいずれかに設けることができる。また、遮光層３０ｂは、黒色以外の色を有する印刷層であってもよいし、塗布により形成されるものであってもよいし、板材３０ａに固定される遮光性シートであってもよい。 The light-shielding layer 30b is composed of, for example, a black printing layer formed on the back surface of the plate material 30a by screen printing or pad printing. Each of the light-transmitting regions 31, 32, and 33 in the plate-shaped portion 30 is formed by a portion of the plate material 30a in which the light-shielding layer 30b is not provided. In the enlarged cross-sectional view of FIG. 4, the translucent region 31 corresponding to the meter display unit 11 and the translucent region 32 corresponding to the multifunction display unit 12 are shown, but the same applies to the translucent region 33. The light-shielding layer 30b can be provided on at least one of the front surface and the back surface of the plate material 30a. Further, the light-shielding layer 30b may be a printing layer having a color other than black, may be formed by coating, or may be a light-shielding sheet fixed to the plate material 30a.
　板状部３０は、主に図２に示すように、本実施形態に特有の形状を有する部分として、平面部Ｐ１～Ｐ３、及び、曲面部Ｃ１，Ｃ２を有する。平面部Ｐ１～Ｐ３の各々に、前述の透光領域３１～３３が設けられている。 As shown mainly in FIG. 2, the plate-shaped portion 30 has flat surface portions P1 to P3 and curved surface portions C1 and C2 as portions having a shape peculiar to the present embodiment. The above-mentioned translucent regions 31 to 33 are provided in each of the flat surface portions P1 to P3.
　平面部Ｐ１は、メータ表示部１１と前後方向において隙間を空けて対向する部分である。平面部Ｐ１の背面とメータ表示部１１の前面１１ａとは、概ね平行（丁度平行も含む。以下同様。）に設定されている。平面部Ｐ２は、多機能表示部１２と前後方向において隙間を空けて対向する部分である。平面部Ｐ２の背面と多機能表示部１２の前面１２ａとは、概ね平行に設定されている。平面部Ｐ３は、ミラー表示部１３と前後方向において隙間を空けて対向する部分である。平面部Ｐ３の背面とミラー表示部１３の前面１３ａとは、概ね平行に設定されている。 The flat surface portion P1 is a portion facing the meter display unit 11 with a gap in the front-rear direction. The back surface of the flat surface portion P1 and the front surface 11a of the meter display unit 11 are set to be substantially parallel (including just parallel. The same shall apply hereinafter). The flat surface portion P2 is a portion facing the multifunction display unit 12 with a gap in the front-rear direction. The back surface of the flat surface portion P2 and the front surface 12a of the multifunction display unit 12 are set to be substantially parallel to each other. The flat surface portion P3 is a portion facing the mirror display unit 13 with a gap in the front-rear direction. The back surface of the flat surface portion P3 and the front surface 13a of the mirror display unit 13 are set to be substantially parallel to each other.
　これら平面部Ｐ１～Ｐ３と複数の表示部の各々との隙間は、例えば１ｍｍ程度に概ね一定（丁度一定も含む。）に設定され、各隙間には、ＯＣＡ（Optical Clear Adhesive）やＯＣＲ（Optical Clear Resin）等の光硬化型接着剤ＯＢが充填されている。つまり、板状部３０は、平面部Ｐ１の背面とメータ表示部１１の前面１１ａとの隙間、平面部Ｐ２の背面と多機能表示部１２の前面１２ａとの隙間、平面部Ｐ３の背面とミラー表示部１３の前面１３ａとの隙間の各々に充填された光硬化型接着剤ＯＢによって、複数の表示部の前面側に固定されている。板状部３０と複数の表示部とは、例えば、紫外線（ＵＶ）硬化型接着剤からなる光硬化型接着剤ＯＢを挟んで重ね合わせた後に、光を照射して接着剤を硬化させる方法（いわゆるオプティカルボンディング）により接着されている。なお、平面部Ｐ１～Ｐ３と複数の表示部の各々との隙間の設定値は任意であり、１ｍｍ以下であっても１ｍｍよりも大きくてもよい。ただし、光硬化型接着剤ＯＢを低減する観点から、当該隙間は、１ｍｍ以下であることが好ましい。 The gap between the flat surfaces P1 to P3 and each of the plurality of display units is set to be substantially constant (including just constant), for example, about 1 mm, and each gap is set to OCA (Optical Clear Adhesive) or OCR (Optical). It is filled with a photocurable adhesive OB such as Clear Resin). That is, the plate-shaped portion 30 has a gap between the back surface of the flat surface portion P1 and the front surface 11a of the meter display unit 11, a gap between the back surface of the flat surface portion P2 and the front surface 12a of the multifunction display unit 12, and the back surface of the flat surface portion P3 and a mirror. Each of the gaps between the display unit 13 and the front surface 13a is fixed to the front surface side of the plurality of display units by the photocurable adhesive OB. A method in which the plate-shaped portion 30 and the plurality of display portions are overlapped with each other by sandwiching a photocurable adhesive OB made of, for example, an ultraviolet (UV) curable adhesive, and then irradiated with light to cure the adhesive ( It is bonded by so-called opticarboning). The set value of the gap between the flat surfaces P1 to P3 and each of the plurality of display units is arbitrary, and may be 1 mm or less or larger than 1 mm. However, from the viewpoint of reducing the photocurable adhesive OB, the gap is preferably 1 mm or less.
　曲面部Ｃ１は、メータ表示部１１と多機能表示部１２との間の隙間を覆うとともに、メータ表示部１１と多機能表示部１２とを繋ぐように形成された曲面形状を有する。具体的に、曲面部Ｃ１は、平面部Ｐ１と平面部Ｐ２とを繋ぐ部分であり、メータ表示部１１の右端部前方と多機能表示部１２の左端部前方との間に位置する。
　曲面部Ｃ２は、メータ表示部１１とミラー表示部１３との間の隙間を覆うとともに、メータ表示部１１とミラー表示部１３とを繋ぐように形成された曲面形状を有する。具体的に、曲面部Ｃ２は、平面部Ｐ１と平面部Ｐ３とを繋ぐ部分であり、メータ表示部１１の左端部前方とミラー表示部１３の右端部前方との間に位置する。 The curved surface portion C1 has a curved surface shape formed so as to cover the gap between the meter display unit 11 and the multifunction display unit 12 and to connect the meter display unit 11 and the multifunction display unit 12. Specifically, the curved surface portion C1 is a portion connecting the flat surface portion P1 and the flat surface portion P2, and is located between the front of the right end portion of the meter display unit 11 and the front of the left end portion of the multifunction display unit 12.
The curved surface portion C2 has a curved surface shape formed so as to cover the gap between the meter display unit 11 and the mirror display unit 13 and to connect the meter display unit 11 and the mirror display unit 13. Specifically, the curved surface portion C2 is a portion connecting the flat surface portion P1 and the flat surface portion P3, and is located between the front of the left end portion of the meter display unit 11 and the front of the right end portion of the mirror display unit 13.
　曲面部Ｃ１，Ｃ２は、各々の表面（前面と背面のうち少なくとも前面）を構成する曲線が接線連続又は曲率連続の条件を満たして形成されている。これにより、透光性カバー２０を透かして見える板状部３０の平面形状の間を連続性のある滑らかな曲面形状で繋ぐことができ、表示装置１００を一体感のある見栄えとすることができる。 The curved surface portions C1 and C2 are formed so that the curves constituting the respective surfaces (at least the front surface of the front surface and the back surface) satisfy the condition of continuous tangential line or continuous curvature. As a result, the flat surface shape of the plate-shaped portion 30 that can be seen through the translucent cover 20 can be connected by a continuous and smooth curved surface shape, and the display device 100 can have a unified appearance. ..
　板状部３０の平面部Ｐ１に位置する透光領域３１は、透光性カバー２０の凹曲面部２１と対向する位置に設けられている。そして、図３に示すように板状部３０を前面側から見ると、透光領域３１と遮光層３０ｂが設けられている領域との境界線Ｌ１は、透光領域３１に向かって膨らむ曲線Ｌ１ａ，Ｌ１ｂを含んで構成されている。具体的に、境界線Ｌ１は、左右方向に長尺の概ね長方形状をなしており、一対の長辺に対応する曲線Ｌ１ａと曲線Ｌ１ｂとが互いに近付くように内側に向かって膨らんでいる。
　このように曲線Ｌ１ａ，Ｌ１ｂを形成することにより、透光性カバー２０の凹曲面部２１と同様に、板状部３０の平面部Ｐ１も凹状に湾曲しているかのような錯覚をユーザに与えることができ、平面部Ｐ１と、透光領域３１を透かして視認されるメータ表示部１１とに曲面感を与えることができる。結果として、表示装置１００を一体感のある見栄えとすることができる。 The translucent region 31 located on the flat surface portion P1 of the plate-shaped portion 30 is provided at a position facing the concave curved surface portion 21 of the translucent cover 20. When the plate-shaped portion 30 is viewed from the front side as shown in FIG. 3, the boundary line L1 between the translucent region 31 and the region where the light-shielding layer 30b is provided is a curve L1a that swells toward the translucent region 31. , L1b are included. Specifically, the boundary line L1 has a substantially rectangular shape that is long in the left-right direction, and the curve L1a and the curve L1b corresponding to the pair of long sides bulge inward so as to approach each other.
By forming the curves L1a and L1b in this way, the user is given the illusion that the flat surface portion P1 of the plate-shaped portion 30 is curved in a concave shape as well as the concave curved surface portion 21 of the translucent cover 20. This makes it possible to give a curved surface feeling to the flat surface portion P1 and the meter display unit 11 which is visually recognized through the translucent region 31. As a result, the display device 100 can have a cohesive appearance.
　また、板状部３０の平面部Ｐ２に位置する透光領域３２は、透光性カバー２０の凸曲面部２２と対向する位置に設けられている。そして、図３に示すように板状部３０を前面側から見ると、透光領域３２と遮光層３０ｂが設けられている領域との境界線Ｌ２は、透光領域３２から離れる方向へ膨らむ曲線Ｌ２ａ，Ｌ２ｂを含んで構成されている。具体的に、境界線Ｌ２は、左右方向に長尺の概ね長方形状をなしており、一対の長辺に対応する曲線Ｌ２ａと曲線Ｌ２ｂとが互いに離れるように外側に向かって膨らんでいる。
　このように曲線Ｌ２ａ，Ｌ２ｂを形成することにより、透光性カバー２０の凸曲面部２２と同様に、板状部３０の平面部Ｐ２も凸状に湾曲しているかのような錯覚をユーザに与えることができ、平面部Ｐ２と、透光領域３２を透かして視認される多機能表示部１２とに曲面感を与えることができる。結果として、表示装置１００を一体感のある見栄えとすることができる。なお、透光性カバー２０の凸曲面部２３と対向する位置に設けられ、板状部３０の平面部Ｐ３に位置する透光領域３３についても同様である。 Further, the translucent region 32 located on the flat surface portion P2 of the plate-shaped portion 30 is provided at a position facing the convex curved surface portion 22 of the translucent cover 20. When the plate-shaped portion 30 is viewed from the front side as shown in FIG. 3, the boundary line L2 between the translucent region 32 and the region where the light-shielding layer 30b is provided is a curve that swells in a direction away from the translucent region 32. It is configured to include L2a and L2b. Specifically, the boundary line L2 has a substantially rectangular shape that is long in the left-right direction, and the curves L2a and the curves L2b corresponding to the pair of long sides bulge outward so as to be separated from each other.
By forming the curves L2a and L2b in this way, the user is given the illusion that the flat surface portion P2 of the plate-shaped portion 30 is also convexly curved in the same manner as the convex curved surface portion 22 of the translucent cover 20. It is possible to give a curved surface feeling to the flat surface portion P2 and the multifunctional display unit 12 which is visually recognized through the translucent region 32. As a result, the display device 100 can have a cohesive appearance. The same applies to the translucent region 33 provided at a position facing the convex curved surface portion 23 of the translucent cover 20 and located on the flat surface portion P3 of the plate-shaped portion 30.

The control unit is composed of a microcomputer including a storage unit including a ROM (Read Only Memory) and a RAM (Random Access Memory), and a CPU (Central Processing Unit) that executes an operation program stored in the ROM. .. The control unit may be provided at a location other than the circuit boards 51 to 53.
　制御部は、車両の各部を制御するＥＣＵ（Electronic Control Unit）、各種センサ、カーナビゲーション装置、バックカメラ、テレビチューナー、サイドカメラ等の車両に構成された各種システムと通信を行い、各種システムから取得した情報を複数の表示部に表示させる制御を行う。具体的に、制御部は、（ｉ）メータ表示部１１に車速、エンジン回転数などの車両に関する計測量を示す画像を表示させ、（ｉｉ）多機能表示部１２にカーナビゲーション情報、娯楽情報、バックモニタ情報を示す画像を表示させ、（ｉｉｉ）ミラー表示部１３にサイドミラー画像を表示させる。 The control unit communicates with various systems configured in the vehicle such as ECU (Electronic Control Unit) that controls each part of the vehicle, various sensors, car navigation device, back camera, TV tuner, side camera, etc., and acquires from various systems.

An image showing the back monitor information is displayed, and the side mirror image is displayed on the (iii) mirror display unit 13.
　また、制御部は、タッチパネルとして構成された多機能表示部１２及びミラー表示部１３の各々に対して行われたユーザによるタッチ操作に応じて、複数の表示部の少なくともいずれかの表示内容を切り替える制御等を行う。なお、タッチ操作とは、透光性カバー２０における多機能表示部１２及びミラー表示部１３と対向する部分の前面をタッチすることでなされる入力操作である。制御部は、当該入力操作の内容をセンサシートからの検出信号に基づき特定することができる。なお、タッチパネルによる入力操作が可能となる対象機器は、複数の表示部に限られず任意であり、前述の各種システム（車両内の任意のＥＣＵやカーナビゲーション等）であってもよい。この場合、制御部は、当該対象機器と公知の手法で通信し、タッチパネルへの入力操作に応じて、当該対象機器を制御すればよい。 Further, the control unit switches at least one of the display contents of the plurality of display units according to the touch operation performed by the user on each of the multifunctional display unit 12 and the mirror display unit 13 configured as the touch panel. Perform control, etc. The touch operation is an input operation performed by touching the front surface of the portion of the translucent cover 20 facing the multifunction display unit 12 and the mirror display unit 13.

The target device capable of input operation by the touch panel is not limited to a plurality of display units, and may be any of the above-mentioned various systems (arbitrary ECU in the vehicle, car navigation, etc.). In this case, the control unit may communicate with the target device by a known method and control the target device in response to an input operation on the touch panel.

（変形例）
　以上では、複数の表示部の各々が液晶ディスプレイから構成されている例を示したが、これに限られない。複数の表示部の少なくとも１つは、有機ＥＬ（Electro-Luminescence）ディスプレイから構成されていてもよい。また、複数の表示部は、少なくとも１つの平面ディスプレイを含んでいれば、曲面状の表示面に画像を表示する曲面ディスプレイを含んでいてもよい。また、複数の表示部は、少なくとも１つの画像表示ディスプレイを含んでいれば、指針式のアナログ計器を含んでいてもよい。複数の表示部が指針式計器を含む場合、例えば、指針式計器のケースの前方端部に板状部３０を固定したり、指針式計器の前面を構成するカバーレンズに光硬化型接着剤ＯＢを介して板状部を固定したりすればよい。また、以上では、複数の表示部が３つの表示部から構成される例を示したが、複数の表示部は、２つの表示部から構成されてもよいし、４つ以上の表示部から構成されてもよい。また、複数の表示部の各々が表示可能な情報は、以上の例に限定されず、目的に応じて任意である。 (Modification example)
In the above, an example in which each of the plurality of display units is composed of a liquid crystal display has been shown, but the present invention is not limited to this. At least one of the plurality of display units may be composed of an organic EL (Electro-Luminescence) display. Further, the plurality of display units may include a curved display that displays an image on a curved display surface as long as it includes at least one flat display. Further, the plurality of display units may include a pointer type analog instrument as long as it includes at least one image display display. When a plurality of display units include a pointer type instrument, for example, a plate-shaped portion 30 is fixed to the front end of the case of the pointer type instrument, or a photocurable adhesive OB is attached to a cover lens constituting the front surface of the pointer type instrument. The plate-shaped portion may be fixed via the above. Further, in the above, the example in which the plurality of display units are composed of three display units has been shown, but the plurality of display units may be composed of two display units or may be composed of four or more display units. May be done. Further, the information that can be displayed by each of the plurality of display units is not limited to the above examples, and is arbitrary depending on the purpose.
　以上では、透光性カバー２０が凹曲面部２１と凸曲面部２２，２３を有する例を示したが、透光性カバー２０は、曲面形状を有するものであれば、その形状は任意である。例えば、透光性カバー２０は、全体が凹状又は凸状に湾曲しているものであってもよい。また、透光領域３１と遮光層３０ｂが設けられている領域との境界線Ｌ１や、透光領域３２と遮光層３０ｂが設けられている領域との境界線Ｌ２に含まれる曲線は、透光性カバー２０の曲面形状と同様に板状部３０が湾曲しているかのような錯覚をユーザに与えることができれば、その構成は任意である。例えば、任意の境界線Ｌ１は、透光領域３１に向かって膨らむ曲線と、透光領域３２から離れる方向へ膨らむ曲線との双方を含んでいてもよい。 In the above, an example in which the translucent cover 20 has a concave curved surface portion 21 and convex curved surface portions 22 and 23 has been shown, but the translucent cover 20 has an arbitrary shape as long as it has a curved surface shape. .. For example, the translucent cover 20 may be entirely curved in a concave shape or a convex shape. Further, the curves included in the boundary line L1 between the translucent region 31 and the region provided with the light-shielding layer 30b and the boundary line L2 between the translucent region 32 and the region provided with the light-shielding layer 30b are translucent. The configuration is arbitrary as long as it can give the user the illusion that the plate-shaped portion 30 is curved as in the curved shape of the sex cover 20. For example, the arbitrary boundary line L1 may include both a curve that bulges toward the translucent region 31 and a curve that bulges toward the direction away from the translucent region 32.
　以上では、板状部３０の平面部Ｐ１～Ｐ３と、複数の表示部の各々との隙間に充填した光硬化型接着剤ＯＢにより、板状部３０を複数の表示部に固定した例を示したが、光硬化型接着剤ＯＢを使用しなくともよい。例えば、板状部３０をインナーケース４０に、接着、嵌合、螺着等の公知の固定手法により固定してもよい。光硬化型接着剤ＯＢを使用しない場合は、板状部３０の板材３０ａの背面にＡＲ処理等の低反射処理を施すことが好ましい。 In the above, an example in which the plate-shaped portion 30 is fixed to the plurality of display portions by the photocurable adhesive OB filled in the gap between the flat portions P1 to P3 of the plate-shaped portion 30 and each of the plurality of display portions is shown. However, it is not necessary to use the photocurable adhesive OB. For example, the plate-shaped portion 30 may be fixed to the inner case 40 by a known fixing method such as adhesion, fitting, or screwing. When the photocurable adhesive OB is not used, it is preferable to apply a low reflection treatment such as AR treatment to the back surface of the plate material 30a of the plate-shaped portion 30.
　複数の表示部のうち隙間を空けて隣り合うもの同士の前面は、傾きと前後方向における位置との少なくともいずれかが異なっていればよい。当該隣り合う表示部の前面同士は、一軸での傾き角が異なっていてもよいし、二軸での傾き角が異なっていてもよいし、三軸での傾き角が異なっていてもよい。これは、複数の表示部の前面と対応して設定される板状部３０の平面部Ｐ１～Ｐ３についても同様である。 Of the plurality of display units, the front surfaces of those adjacent to each other with a gap may differ in at least one of the inclination and the position in the front-rear direction. The front surfaces of the adjacent display units may have different tilt angles on one axis, different tilt angles on two axes, or different tilt angles on three axes. This also applies to the flat surface portions P1 to P3 of the plate-shaped portion 30 that are set corresponding to the front surfaces of the plurality of display units.
　表示装置１００が搭載される乗り物は、自動四輪車でなく、自動二輪車等の車両であってもよいし、車両以外の船舶、航空機、スノーモービルなどの乗り物であってもよい。表示装置１００は、乗り物の運転席の近傍に設けることが好ましい。 The vehicle on which the display device 100 is mounted may be a vehicle such as a motorcycle instead of a motorcycle, or a vehicle such as a ship, an aircraft, or a snowmobile other than the vehicle. The display device 100 is preferably provided near the driver's seat of the vehicle.
（１）以上に説明した乗り物（例えば車両）に搭載される表示装置１００は、隙間を空けて隣り合う第１表示部（例えばメータ表示部１１）及び第２表示部（例えば多機能表示部１２又はミラー表示部１３）と、板状部３０と、透光性カバー２０と、を備える。板状部３０は、第１表示部及び第２表示部の各々が表示する情報を視認可能とする透光領域（例えば、透光領域３１，３２、又は、透光領域３１，３３）を有し、第１表示部及び第２表示部を前面側から覆う。透光性カバー２０は、曲面形状を有し、板状部３０を前面側から覆う。第１表示部は、平面状の前面に画像を表示するディスプレイからなる。また、第１表示部の前面と第２表示部の前面は、傾きと前後方向における位置との少なくともいずれかが異なる。そして、板状部３０は、前記隙間を覆うとともに、第１表示部と第２表示部とを繋ぐように形成された曲面形状の曲面部（例えば曲面部Ｃ１又は曲面部Ｃ２）を有する。
　この構成によれば、透光性カバー２０と第１表示部及び第２表示部との間の空間に光硬化型接着剤ＯＢを充填せずに済むとともに、板状部３０の曲面部によって透光性カバー２０の曲面形状と対応した曲面感を創出することができる。結果として、光硬化型接着剤ＯＢの使用量を低減し、又は使用せずに、一体感のある見栄えの表示装置１００を提供することができる。 (1) The display device 100 mounted on the vehicle (for example, a vehicle) described above has a first display unit (for example, a meter display unit 11) and a second display unit (for example, a multifunctional display unit 12) that are adjacent to each other with a gap. Alternatively, a mirror display unit 13), a plate-shaped portion 30, and a translucent cover 20 are provided. The plate-shaped portion 30 has a translucent region (for example, translucent regions 31, 32, or translucent regions 31, 33) that makes it possible to visually recognize the information displayed by each of the first display unit and the second display unit. Then, the first display unit and the second display unit are covered from the front side. The translucent cover 20 has a curved surface shape and covers the plate-shaped portion 30 from the front surface side. The first display unit includes a display that displays an image on a flat front surface. Further, at least one of the inclination and the position in the front-rear direction is different between the front surface of the first display unit and the front surface of the second display unit. The plate-shaped portion 30 has a curved surface portion (for example, a curved surface portion C1 or a curved surface portion C2) formed so as to cover the gap and connect the first display portion and the second display portion.
According to this configuration, it is not necessary to fill the space between the translucent cover 20 and the first display portion and the second display portion with the photocurable adhesive OB, and the curved surface portion of the plate-shaped portion 30 allows transparency. It is possible to create a curved surface feeling corresponding to the curved surface shape of the optical cover 20. As a result, it is possible to provide the display device 100 having a sense of unity and appearance without using or reducing the amount of the photocurable adhesive OB used.
（２）板状部３０は、第１表示部及び第２表示部の各々の前面に光硬化型接着剤ＯＢを介して固定されている。
　この構成によれば、透光性カバー２０と第１表示部及び第２表示部との間の空間に光硬化型接着剤ＯＢを充填せずに済み、必要最小限の箇所に光硬化型接着剤ＯＢを使用すればよいため、光硬化型接着剤ＯＢの使用量を低減しつつ、板状部３０と第１表示部及び第２表示部との間で反射する外光を低減することができる。 (2) The plate-shaped portion 30 is fixed to the front surfaces of the first display portion and the second display portion via a photocurable adhesive OB.
According to this configuration, it is not necessary to fill the space between the translucent cover 20 and the first display unit and the second display unit with the photocurable adhesive OB, and the photocurable adhesive is adhered to the minimum necessary portion. Since the agent OB may be used, it is possible to reduce the amount of the photocurable adhesive OB used and the external light reflected between the plate-shaped portion 30 and the first display portion and the second display portion. it can.
（３）また、第２表示部は、平面状の前面に画像を表示するディスプレイから構成されてもよく、この場合、板状部３０における第１表示部及び第２表示部の各々と対向する部分（例えば、平面部Ｐ１と平面部Ｐ２、又は、平面部Ｐ１と平面部Ｐ３）は、平面状をなす。
　この構成によれば、板状部３０と第１表示部及び第２表示部との一体感を増すことができ、光硬化型接着剤ＯＢを使用する場合には、必要最小限の箇所に光硬化型接着剤ＯＢを使用すればよいため、光硬化型接着剤ＯＢの使用量を低減しつつ、板状部３０と第１表示部及び第２表示部との間で反射する外光を低減することができる。 (3) Further, the second display unit may be composed of a display that displays an image on a flat front surface, and in this case, the second display unit faces each of the first display unit and the second display unit in the plate-shaped unit 30. The portion (for example, the flat surface portion P1 and the flat surface portion P2, or the flat surface portion P1 and the flat surface portion P3) has a flat shape.
According to this configuration, the sense of unity between the plate-shaped portion 30 and the first display portion and the second display portion can be increased, and when the photocurable adhesive OB is used, light is applied to the minimum necessary portion. Since the curable adhesive OB may be used, the amount of the photocurable adhesive OB used is reduced, and the external light reflected between the plate-shaped portion 30 and the first display portion and the second display portion is reduced. can do.
（４）板状部３０は、透光性を有する板材３０ａと、板材３０ａの前面と背面の少なくともいずれかに設けられた遮光層３０ｂとを有し、透光領域（例えば、透光領域３１，３２、又は、透光領域３１，３３）は、板材３０ａにおける遮光層３０ｂが設けられていない領域であってもよい。 (4) The plate-shaped portion 30 has a translucent plate material 30a and a light-shielding layer 30b provided on at least one of the front surface and the back surface of the plate material 30a, and has a translucent region (for example, a translucent region 31). , 32, or the translucent regions 31, 33) may be regions in the plate material 30a where the light-shielding layer 30b is not provided.
（５）透光性カバー２０は、第１表示部と対向する部分に、後方に向かって凹む凹曲面部２１を有する。第１表示部が表示する情報を視認可能とする透光領域（例えば透光領域３１）を第１透光領域とすると、板状部３０を前面側から見て、第１透光領域と遮光層３０ｂが設けられている領域との境界線Ｌ１は、第１透光領域に向かって膨らむ曲線Ｌ１ａ，Ｌ１ｂを含んで構成されている。
　この構成によれば、透光性カバー２０の凹曲面部２１と同様に、板状部３０も凹状に湾曲しているかのような錯覚をユーザに与えることができ、板状部３０と、第１透光領域を透かして視認される第１表示部とに曲面感を与えることができる。結果として、表示装置１００を一体感のある見栄えとすることができる。 (5) The translucent cover 20 has a concave curved surface portion 21 that is recessed rearward at a portion facing the first display portion. Assuming that the translucent region (for example, the translucent region 31) that makes the information displayed by the first display unit visible is the first translucent region, the plate-shaped portion 30 is viewed from the front side and is shielded from the first translucent region. The boundary line L1 with the region where the layer 30b is provided includes curves L1a and L1b that bulge toward the first translucent region.
According to this configuration, similarly to the concave curved surface portion 21 of the translucent cover 20, the plate-shaped portion 30 can give the user the illusion that the plate-shaped portion 30 is also curved in a concave shape. 1 It is possible to give a curved surface feeling to the first display unit which is visually recognized through the translucent area. As a result, the display device 100 can have a cohesive appearance.
（６）透光性カバー２０は、第２表示部と対向する部分に、前方に向かって凸となる凸曲面部（凸曲面部２２又は２３）を有する。第２表示部が表示する情報を視認可能とする透光領域（例えば、透光領域３２又は３３）を第２透光領域とすると、板状部３０を前面側から見て、第２透光領域と遮光層３０ｂが設けられている領域との境界線Ｌ２は、第２透光領域から離れる方向へ膨らむ曲線Ｌ２ａ，Ｌ２ｂを含んで構成されている。
　この構成によれば、透光性カバー２０の凸曲面部と同様に、板状部３０も凸状に湾曲しているかのような錯覚をユーザに与えることができ、板状部３０と、第２透光領域を透かして視認される第２表示部とに曲面感を与えることができる。結果として、表示装置１００を一体感のある見栄えとすることができる。 (6) The translucent cover 20 has a convex curved surface portion (convex curved surface portion 22 or 23) that is convex toward the front in a portion facing the second display portion. Assuming that the translucent region (for example, the translucent region 32 or 33) that makes the information displayed by the second display unit visible is the second translucent region, the plate-shaped portion 30 is viewed from the front side and the second translucent region is viewed. The boundary line L2 between the region and the region where the light-shielding layer 30b is provided includes curves L2a and L2b that swell in a direction away from the second light-transmitting region.
According to this configuration, similarly to the convex curved surface portion of the translucent cover 20, the plate-shaped portion 30 can give the user the illusion that the plate-shaped portion 30 is also convexly curved. 2 It is possible to give a curved surface feeling to the second display unit that is visually recognized through the translucent area. As a result, the display device 100 can have a cohesive appearance.
