Specifically, the mirror display unit 13 displays a side mirror image that is captured by a side camera (not shown) and shows the scenery behind the left side of the vehicle. The mirror display unit 13 is composed of, for example, a TFT-type liquid crystal display that is rectangular when viewed from the front. For example, a capacitive sensor sheet (not shown) is provided on the front side of the mirror display unit 13. This sensor sheet is configured to be able to detect a touch operation performed by a user's hand touching the front of a portion (a convex curved surface portion 23 described later) of the translucent cover 20 that faces the mirror display unit 13 in the front-rear direction. The mirror display unit 13 is capable of displaying an image captured by a side camera whose shooting direction has been adjusted according to the touch operation detected by this 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.

As shown in FIG. 2, the front surface 11a of the meter display section 11 is located behind the front surface 12a of the multi-function display section 12 and the front surface 13a of the mirror display section 13. Further, the front surface 12a of the multi-function display section 12 is tilted counterclockwise in FIG. 2 with respect to the front surface 11a of the meter display section 11. Further, the front surface 13a of the mirror display section 13 is inclined clockwise in FIG. 2 with respect to the front surface 11a of the meter display section 11. Further, these plurality of display sections are arranged so that adjacent display sections are spaced apart from each other in the left-right direction.

As shown in FIG. 2, the translucent cover 20 is a translucent plate material that covers the plurality of display sections from the front side. The translucent cover 20 is formed to have a curved shape, for example, in accordance with the design of an instrument panel of a vehicle in which the display device 100 is mounted. The translucent cover 20 has a concave curved surface portion 21 and convex curved surface portions 22 and 23 as curved portions. The concave curved surface portion 21 faces the meter display portion 11 in the front-rear direction and has a curved shape that is concave toward the rear. The convex curved surface section 22 faces the multi-function display section 12 in the front-rear direction and has a curved surface shape that is convex toward the front. The convex curved surface portion 23 faces the mirror display portion 13 in the front-rear direction and has a curved surface shape that is convex toward the front.

The plate-shaped portion 30 is a plate-shaped portion that covers the multiple display units from the front side and is located between the multiple display units 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 Figure 3, the plate-shaped portion 30 has translucent regions 31, 32, and 33 that allow the images displayed by the meter display unit 11, the multifunction display unit 12, and the mirror display unit 13 to be viewed.

Specifically, the plate portion 30 includes a plate material 30a and a light shielding layer 30b, as shown in FIG. The plate material 30a is, for example, a plate-shaped member made of a translucent resin.

Here, the above-mentioned translucent cover 20 is formed, for example, from a mixed material of polycarbonate (PC) and acrylic (PMMA) in a smoke color, and the light transmittance is set to about 50%. In addition, the plate material 30a is formed, for example, from polycarbonate (PC) in a smoke color, and the light transmittance is set to about 50%. In this way, by limiting the intrusion of external light from the front of the display device 100, it is possible to reduce the sense of incongruity caused by providing the plate-shaped part 30 in addition to the translucent cover 20, and to improve the sense of unity of the display device 100. Note that the light transmittance of each of the translucent cover 20 and the plate material 30a is arbitrary, and may be 80% or 30%, etc. In addition, 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.

Furthermore, low reflection treatment may be applied to at least one of the front and back surfaces of the translucent cover 20 and at least one of the front and back surfaces of the plate material 30a. 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 rear surface of the translucent cover 20 and the front surface of the plate material 30a. . Note that the low reflection treatment may be AG (Anti-Glare) treatment or the like. As a method for low reflection treatment, film lamination, film insert molding (IML), sputtering, etc. can be used. By preventing reflection in this way, it is possible to reduce the discomfort caused by providing the plate-like portion 30 in addition to the translucent cover 20, and it is possible to improve the sense of unity of the display device 100.

The light shielding layer 30b is made of a black printed layer formed on the back surface of the plate material 30a by, for example, 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 where the light-shielding layer 30b is not provided. Although the enlarged cross-sectional view of FIG. 4 shows the light-transmitting region 31 corresponding to the meter display section 11 and the light-transmitting region 32 corresponding to the multi-function display section 12, the same applies to the light-transmitting region 33. Note that 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. Moreover, the light-shielding layer 30b may be a printed 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.

As mainly shown in FIG. 2, the plate-shaped portion 30 has flat portions P1 to P3 and curved portions C1 and C2 as portions having a shape unique to this embodiment. The aforementioned light-transmitting regions 31-33 are provided in each of the planar portions P1-P3.

The plane portion P1 is a portion that faces the meter display portion 11 with a gap in the front-rear direction. The back surface of the plane section P1 and the front surface 11a of the meter display section 11 are set to be approximately parallel (including exactly parallel; the same applies hereinafter). The plane portion P2 is a portion that faces the multifunction display portion 12 with a gap in the front-rear direction. The back surface of the plane section P2 and the front surface 12a of the multi-function display section 12 are set approximately parallel to each other. The plane portion P3 is a portion that faces the mirror display portion 13 with a gap in the front-rear direction. The back surface of the plane portion P3 and the front surface 13a of the mirror display portion 13 are set approximately parallel to each other.

The gaps between these plane parts P1 to P3 and each of the plurality of display parts are set to be approximately constant (including exactly constant), for example, about 1 mm. It is filled with a photocurable adhesive OB such as Clear Resin). In other words, the plate-shaped portion 30 includes a gap between the back surface of the planar section P1 and the front surface 11a of the meter display section 11, a gap between the back surface of the planar section P2 and the front surface 12a of the multi-function display section 12, a gap between the back surface of the planar section P3 and the mirror. It is fixed to the front side of the plurality of display parts by a photocurable adhesive OB filled in each of the gaps between the display part 13 and the front surface 13a. The plate-shaped portion 30 and the plurality of display portions are formed by, for example, stacking a photo-curing adhesive OB made of an ultraviolet (UV)-curing adhesive and then curing the adhesive by irradiating light. They are bonded by so-called optical bonding. Note that the setting value of the gap between the plane parts P1 to P3 and each of the plurality of display parts 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.

The curved surface portion C1 has a curved shape formed to cover the gap between the meter display portion 11 and the multifunction display portion 12 and to connect the meter display portion 11 and the multifunction display portion 12. Specifically, the curved surface portion C1 is a portion that connects the flat portion P1 and the flat portion P2, and is located between the front right end of the meter display portion 11 and the front left end of the multifunction display portion 12.
The curved surface portion C2 has a curved shape formed to cover the gap between the meter display portion 11 and the mirror display portion 13 and to connect the meter display portion 11 and the mirror display portion 13. Specifically, the curved surface portion C2 is a portion that connects the flat portion P1 and the flat portion P3, and is located between the front left end of the meter display portion 11 and the front right end of the mirror display portion 13.

The curved surface portions C1 and C2 are formed such that the curves constituting each surface (at least the front surface of the front surface and the back surface) satisfy the condition of tangential continuity or curvature continuity. As a result, the planar shapes of the plate portions 30 that can be seen through the transparent cover 20 can be connected with a continuous and smooth curved shape, and the display device 100 can have a unified appearance. .

The light-transmitting region 31 located on the plane portion P1 of the plate-shaped portion 30 is provided at a position facing the concave curved surface portion 21 of the light-transmitting cover 20. When the plate-shaped portion 30 is viewed from the front side as shown in FIG. , L1b. Specifically, the boundary line L1 has a generally rectangular shape that is elongated in the left-right direction, and swells inward so that the curve L1a and the curve L1b corresponding to the pair of long sides approach each other.
By forming the curves L1a and L1b in this way, the user is given the illusion that the flat part P1 of the plate part 30 is also concavely curved, similar to the concave curved part 21 of the translucent cover 20. This makes it possible to give a curved surface to the flat portion P1 and the meter display portion 11 that is visible through the light-transmitting region 31. As a result, the display device 100 can have a unified appearance.

Further, the light-transmitting region 32 located on the flat surface P2 of the plate-shaped portion 30 is provided at a position facing the convex curved surface portion 22 of the light-transmitting cover 20. When the plate-shaped portion 30 is viewed from the front side as shown in FIG. It is configured to include L2a and L2b. Specifically, the boundary line L2 has a generally rectangular shape that is elongated in the left-right direction, and swells outward so that the curve L2a and the curve L2b corresponding to the pair of long sides are separated from each other.
By forming the curves L2a and L2b in this way, the user is given the illusion that the flat part P2 of the plate-shaped part 30 is also curved in a convex shape, similar to the convex curved part 22 of the translucent cover 20. It is possible to give a curved surface to the flat portion P2 and the multifunctional display portion 12 that is visible through the light-transmitting region 32. As a result, the display device 100 can have a unified appearance. The same applies to the light-transmitting region 33 provided at a position facing the convex curved surface portion 23 of the light-transmitting cover 20 and located on the flat portion P3 of the plate-like portion 30.

The inner case 40 is located on the back side of the plate-shaped portion 30, and is a case that accommodates each of the plurality of display portions, and is made of, for example, resin. In the inner case 40, the front surface other than the portion housing each of the plurality of display sections is formed in a shape corresponding to the shape of the plate-like section 30. Note that the plate-like portion 30 is fixed to the front surface of each of the plurality of display portions via the photocurable adhesive OB as described above, but the portions that are not filled with the photocurable adhesive OB (for example, The outer edge portion of the plate-like portion 30 may be fixed to the front surface of the inner case 40 by a known fixing method such as adhesion, fitting, or screwing.

The circuit boards 51 to 53 are located at the rear of the inner case 40 and are composed of printed circuit boards on which drive circuits for driving each of the plurality of display sections are mounted. The circuit board 51 is located behind the meter display section 11, the circuit board 52 is located behind the multifunction display section 12, and the circuit board 53 is located behind the mirror display section 13. A control unit (not shown) that controls the overall operation of the display device 100 is mounted on at least one of the circuit boards 51 to 53. 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 operating program stored in the ROM. . Note that the control section may be provided at a location other than the circuit boards 51 to 53.

The control unit communicates with various systems configured in the vehicle such as the ECU (Electronic Control Unit) that controls each part of the vehicle, various sensors, car navigation equipment, back camera, TV tuner, side camera, etc., and acquires information from the various systems. Control is performed to display the information on multiple display units. Specifically, the control section (i) causes the meter display section 11 to display an image showing measured quantities related to the vehicle, such as vehicle speed and engine rotation speed, and (ii) causes the multifunction display section 12 to display car navigation information, entertainment information, An image indicating rear monitor information is displayed, and (iii) a side mirror image is displayed on the mirror display section 13.

Further, the control unit switches the display content of at least one of the plurality of display units in response to a touch operation performed by the user on each of the multi-function display unit 12 and the mirror display unit 13 configured as a touch panel. Performs control, etc. Note that the touch operation is an input operation performed by touching the front surface of the portion of the translucent cover 20 that faces the multifunction display section 12 and the mirror display section 13. The control unit can specify the content of the input operation based on the detection signal from the sensor sheet. Note that the target device that allows input operations using the touch panel is not limited to the plurality of display units, and may be any of the various systems described above (such as any ECU or car navigation system in the vehicle). In this case, the control unit may communicate with the target device using a known method and control the target device in response to input operations on the touch panel.

The board holder 60 is a frame located at the rear of the inner case 40 and holds the circuit boards 51 to 53. Although FIG. 2 shows an example in which the circuit boards 51 to 53 are held on the back side of the board holder 60, the manner in which the circuit boards 51 to 53 are held is arbitrary, and they may be held on the front side. good.

The outer case 70 accommodates the plurality of display sections, the plate-like section 30, the inner case 40, the circuit boards 51 to 53, and the board holder 60, and is made of, for example, a light-shielding resin, so that it is It is shaped like an open box. The transparent cover 20 is fixed to the open end of the outer case 70 by a known fixing method such as adhesion, fitting, or screwing. The outer case 70 to which the translucent cover 20 is attached constitutes the exterior of the display device 100. The description of the display device 100 according to this embodiment is above.

Note that the present invention is not limited to the above embodiments and drawings. It is possible to make changes (including deletion of constituent elements) as appropriate without changing the gist of the present invention.

(Modified example)
Although an example has been described above in which each of the plurality of display units is configured from a liquid crystal display, the present invention is not limited to this. At least one of the plurality of display units may include an organic EL (Electro-Luminescence) display. Further, as long as the plurality of display units includes at least one flat display, they may also include a curved display that displays an image on a curved display surface. Furthermore, the plurality of display units may include pointer-type analog instruments as long as they include at least one image display display. In the case where the plurality of display units include pointer-type instruments, for example, the plate-shaped portion 30 may be fixed to the front end of the case of the pointer-type instrument, or a light-curing adhesive OB may be applied to the cover lens that constitutes the front surface of the pointer-type instrument. What is necessary is just to fix a plate-shaped part via. Furthermore, in the above example, the plurality of display sections is composed of three display sections, but the plurality of display sections may be composed of two display sections or four or more display sections. may be done. Further, the information that can be displayed by each of the plurality of display sections is not limited to the above example, but is arbitrary depending on the purpose.

In the above example, the light-transmitting cover 20 has the concave curved surface portion 21 and the convex curved surface portions 22 and 23, but the shape of the light-transmitting cover 20 may be arbitrary as long as it has a curved shape. . For example, the entire translucent cover 20 may be curved in a concave or convex shape. Further, the curve included in the boundary line L1 between the light-transmitting region 31 and the region where the light-shielding layer 30b is provided, and the boundary line L2 between the light-transmitting region 32 and the region where the light-shielding layer 30b is provided, is The configuration is arbitrary as long as it can give the user the illusion that the plate portion 30 is curved in the same way as the curved shape of the sexual cover 20. For example, the arbitrary boundary line L1 may include both a curved line that expands toward the transparent area 31 and a curved line that expands in a direction away from the transparent area 32.

In the above, an example is shown in which the plate-like part 30 is fixed to a plurality of display parts using a photocurable adhesive OB filled in the gaps between the flat parts P1 to P3 of the plate-like part 30 and each of the plurality of display parts. However, the photocurable adhesive OB may not be used. 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 perform low reflection treatment such as AR treatment on the back surface of the plate material 30a of the plate-shaped portion 30.

The front surfaces of the plurality of display sections that are adjacent to each other with a gap between them 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 inclination angles in one axis, different inclination angles in two axes, or different inclination angles in three axes. This also applies to the flat parts P1 to P3 of the plate-shaped part 30, which are set to correspond to the front surfaces of the plurality of display parts.

The vehicle on which the display device 100 is mounted may be a vehicle such as a motorcycle instead of a four-wheeled motor vehicle, or a vehicle other than a vehicle such as a ship, an aircraft, or a snowmobile. The display device 100 is preferably provided near the driver's seat of the vehicle.

(1) The display device 100 mounted on the vehicle (e.g., a vehicle) described above includes a first display unit (e.g., a meter display unit 11) and a second display unit (e.g., a multifunction display unit 12 or a mirror display unit 13) adjacent to each other with a gap therebetween, a plate-shaped unit 30, and a light-transmitting cover 20. The plate-shaped unit 30 has a light-transmitting area (e.g., light-transmitting areas 31, 32, or light-transmitting areas 31, 33) that allows the information displayed by each of the first display unit and the second display unit to be visually recognized, and covers the first display unit and the second display unit from the front side. The light-transmitting cover 20 has a curved shape and covers the plate-shaped unit 30 from the front side. The first display unit is made of a display that displays an image on a planar front surface. In addition, the front surface of the first display unit and the front surface of the second display unit differ in at least one of the inclination and the position in the front-rear direction. The plate-like portion 30 has a curved surface portion (for example, the curved surface portion C1 or the curved surface portion C2) that is curved and is 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 spaces between the light-transmitting cover 20 and the first and second display units with the light-curing adhesive OB, and the curved surface of the plate-shaped portion 30 can create a curved appearance that corresponds to the curved shape of the light-transmitting cover 20. As a result, it is possible to provide a display device 100 that looks unified, with a reduced amount of light-curing adhesive OB used or without the use of the light-curing adhesive OB.

(2) The plate-like section 30 is fixed to the front surface of each of the first display section and the second display section via a photocurable adhesive OB.
According to this configuration, it is not necessary to fill the space between the light-transmitting cover 20 and the first display section and the second display section with the light-curing adhesive OB, and the light-curing adhesive OB can be applied to the minimum necessary locations. Since it is sufficient to use the adhesive OB, it is possible to reduce the amount of the photocurable adhesive OB used and reduce external light reflected between the plate-shaped part 30 and the first display part and the second display part. can.

(3) Furthermore, the second display section may be composed of a display that displays an image on a planar front surface, and in this case, the second display section may be configured of a display that displays an image on a flat front surface, and in this case, the second display section may be configured such that the second display section faces each of the first display section and the second display section in the plate-shaped section 30. The portions (for example, the plane portion P1 and the plane portion P2, or the plane portion P1 and the plane portion P3) have a planar shape.
According to this configuration, it is possible to increase the sense of unity between the plate-shaped part 30 and the first display part and the second display part, and when using the photocurable adhesive OB, light is applied to the minimum necessary location. Since it is sufficient to use a curable adhesive OB, the amount of light curable adhesive OB used can be reduced while reducing external light reflected between the plate-shaped portion 30 and the first display section and the second display section. can do.

(4) The plate-like portion 30 includes a light-transmitting 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 includes a light-transmitting region (for example, a light-transmitting region 31 , 32 or the light-transmitting regions 31, 33) may be regions in the plate material 30a where the light-shielding layer 30b is not provided.

(5) The translucent cover 20 has a concave curved surface portion 21 that is recessed toward the rear in a portion facing the first display portion. If the light-transmitting area (for example, the light-transmitting area 31) that makes the information displayed by the first display part visible is the first light-transmitting area, then when the plate-shaped part 30 is viewed from the front side, the first light-transmitting area and the light-shielding area are The boundary line L1 with the region where the layer 30b is provided includes curves L1a and L1b that swell toward the first light-transmitting region.
According to this configuration, it is possible to give the user the illusion that the plate part 30 is also concavely curved, similar to the concave curved surface part 21 of the translucent cover 20, and the plate part 30 and the A curved surface feeling can be given to the first display section that is visible through the first light-transmitting area. As a result, the display device 100 can have a unified appearance.

(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 section. If the light-transmitting area (for example, the light-transmitting area 32 or 33) that makes the information displayed by the second display part visible is the second light-transmitting area, then when the plate-shaped part 30 is viewed from the front side, the second light-transmitting area is the second light-transmitting area. A 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 the direction away from the second light-transmitting region.
According to this configuration, it is possible to give the user the illusion that the plate-like portion 30 is also curved in a convex shape, similar to the convex-curved surface portion of the translucent cover 20, and the plate-like portion 30 and the A curved surface feeling can be given to the second display section that is visible through the second light-transmitting area. As a result, the display device 100 can have a unified appearance.

In the above description, descriptions of known technical matters have been omitted as appropriate in order to facilitate understanding of the present invention.
