In FIG. 3, the left side of the figure is the front side, and the right side of the figure is the back side.

  First, the first display 10 of the display device 100 will be described. As shown in FIG. 2, the 1st display 10 has the 1st translucent board | substrate 31 arrange | positioned at the front surface, and the flat 1st control board (support plate) 51 is arrange | positioned at the back surface. The first translucent substrate 31 is made of transparent glass or smoked glass. The first control substrate 51 is a resin substrate that includes a circuit that supports the first light-transmitting substrate 31 and other members and controls a light source disposed on the first control substrate 51. In addition, the material of the 1st translucent board | substrate 31 will not be restricted to glass, if it has translucency. For example, a transparent resin such as polymethyl methacrylate (PMMA) or polycarbonate (PC) or a smoke resin may be used. Moreover, the 1st translucent board | substrate 31 may be colored in arbitrary colors so that it may have translucency.

  A first display panel 11, which is a thin film transistor (TFT) liquid crystal panel, is disposed on the back surface of the first translucent substrate 31. In addition, the control part, wiring, etc. of the 1st display board 11 can use a prior art, and are abbreviate | omitting description.

  More specifically, as shown in FIG. 4A, the first display panel 11 is attached to the back surface of the first light transmissive substrate 31 using a light transmissive adhesive 13. The light transmissive adhesive 13 is a light transmissive adhesive, and can use OCA (Optical Clear Adhesive) or OCR (Optical Clear Resin). The translucent adhesive 13 preferably has the same or equivalent refractive index as the first translucent substrate 31. By using the translucent adhesive 13 having the same or equivalent refractive index as that of the first translucent substrate 31, the first display panel can be used as compared with the case of using the translucent adhesive 13 having a different refractive index. 11 display distortion is reduced. Further, by filling the space between the first light-transmitting substrate 31 and the first display plate 11 with the light-transmitting adhesive 13 having the same or equivalent refractive index as that of the first light-transmitting substrate 31, Loss can be reduced.

  A light shielding layer 36 is provided around the first display panel 11. The light shielding layer 36 is provided on the back surface of the first translucent substrate 31. The light shielding layer 36 can be formed on the back surface of the first translucent substrate 31 by silk printing, offset printing, coating, or the like. The light shielding layer 36 has a dark color tone such as black, shields light unnecessary for display, and makes the difference in light between the first display 10 and the second display 20 inconspicuous. It is a member for making it.

  A non-reflective layer 33 is provided on the entire front surface of the first translucent substrate 31. The non-reflective layer 33 is a layer subjected to an antiglare treatment or an antireflection treatment. The non-reflective layer 33 is a member for suppressing the light incident from the front side of the first light transmissive substrate 31 from being reflected and improving the visibility of the first display panel 11.

  Returning to FIG. 2, a light guide 80 having a size enough to cover the first display plate 11 is arranged on the back side of the first display plate 11 in parallel with and spaced from the first display plate 11. As shown in FIG. 3A, one end of the light guide 80 is bent, and the end 82 faces the first light source (first backlight light source) 90. The light guide 80 is made of, for example, transparent polymethylmethacrylate (PMMA), receives light emitted from the first light source 90 at the end portion 82, reflects the light inside the light guide 80, and 1 Discharge from the surface facing the display panel 11. As described above, the light guide 80 has a role of evenly distributing the light from the first light source 90 over the entire surface of the first display panel 11.

  The first light source 90 is disposed on the first control board 51. The first light source 90 is a white light LED (Light Emitting Diode) backlight light source that uniformly illuminates the first display plate 11 via the light guide 80.

  As shown in FIG. 2 and FIG. 3A, the first control board 51 surrounds the first light source 90 and the light guide 80 from the first control board 51 toward the first display panel 11. Partition plates (first partition plates) 62 and 62a are erected. The partition plate 62 is also provided on the back side of the light guide 80 so as to be separated from the light guide 80. The partition plates 62 and 62 a are reflection plates for reflecting the light from the first light source 90 and the light leaking from the light guide 80 toward the first display plate 11. The partition plate 62a is a partition plate provided on the second display device 20 side, and the partition plate 62 is a partition plate provided in other portions. The partition plates 62 and 62a are made of, for example, white polypropylene (PP) resin.

  The upper end of the partition plate 62 a is not in contact with any of the first translucent substrate 31, the first display plate 11, and the second display plate 21. In other words, the height of the partition plate 62a from the first control board 51 is lower than the height of the first display board 11 and the second display board 21 from the first control board 51. Here, the “height” is a vertical distance in FIGS. 2A and 2B, and a horizontal distance in FIGS. 3A and 3B.

  Next, the second display device 20 will be described. As shown in FIG. 2, the second display 20 has a second light-transmitting substrate 32 disposed on the front surface and a flat second control substrate (support plate) 52 disposed on the rear surface. The materials and roles of the second light transmitting substrate 32 and the second control substrate 52 are the same as those of the first light transmitting substrate 31 and the first control substrate 51.

  A second display panel 21, which is a passive liquid crystal panel, is disposed on the back surface of the second light transmissive substrate 32. Conventional techniques can be used for the control unit, wiring, and the like of the second display panel 21, and the description is omitted.

  More specifically, as shown in FIG. 4A, the second display panel 21 is attached to the back surface of the second light transmissive substrate 32 using a light transmissive adhesive 23. The translucent adhesive 23 is a light-transmitting adhesive, and OCA or OCR can be used. The translucent adhesive 23 preferably has the same or equivalent refractive index as that of the second translucent substrate 32. The reason for this is as described in the translucent adhesive 13.

  A light shielding layer 37 is provided around the second display panel 21. The light shielding layer 37 is provided on the back surface of the second light transmissive substrate 32. The role and formation method of the light shielding layer 37 are the same as those of the light shielding layer 36.

  The second display panel 21 includes a diffusion layer 24 on the back surface thereof. The diffusion layer 24 is a member for diffusing light so that light from the second light source 92 is evenly applied to the second display panel 21. The diffusion layer 24 can be formed, for example, by pasting a polycarbonate sheet, which is translucent printed to reduce the transmittance, on the back surface of the second display panel 21. Or you may print directly on the back surface of the 2nd display board 21. FIG. Although not shown, the second display panel 21 may not include the diffusion layer 24. Conversely, the first display panel 11 may also be provided with a diffusion layer on the back surface thereof.

  A non-reflective layer 33 is provided on the entire front surface of the second translucent substrate 32. The non-reflective layer 33 is provided integrally on the front surfaces of the first and second translucent substrates 31 and 32 after the first display 10 and the second display 20 that do not have the non-reflective layer are combined. It is a thing. The non-reflective layer 33 is a member that suppresses reflection of light incident from the front side of the second light-transmissive substrate 32 and improves the visibility of the second display panel 21.

  2 and 3, the second control board 52 includes a first warning light emission source (first emission source) 94 and a second warning light emission source (first emission source) shown in FIG. ) 96, a light emission source 92a (second light emission source) shown in FIG. 2B, and a light emission source 92b and a light emission source 92c (both are second light emission sources) shown in FIG. 3B. The light emission sources 92a, 92b, and 92c, the first warning light emission source 94, and the second warning light emission source 96 are collectively referred to as a second light source (second backlight light source) 92.

  The light emitting sources 92 a, 92 b, and 92 c are white light LED backlight sources for directly illuminating the second display panel 21 from the back surface, and a plurality of light emitting sources 92 a, 92 b, and 92 c are disposed on the second control board 52. The light emitting sources 92a, 92b, and 92c are also arranged at positions not shown in FIGS.

  The second control board 52 is provided with adjusting means (not shown) for adjusting the light emission intensity of the light emitting sources 92a, 92b, and 92c. The emission intensity can be easily adjusted by changing the current value or voltage value of the light source. The adjusting means is for adjusting the visual luminance of the first display 10 and the second display 20 to the same level when the display device 100 is assembled.

  The first warning light emission source 94 and the second warning light emission source 96 are red or yellow LEDs for individually illuminating the first warning indication 27 and the second warning indication 28 of the second display panel 21, respectively. It is a luminescence source. The first warning light emission source 94 and the second warning light emission source 96 are also white light, and the first warning indication 27 and the second warning indication 28 of the second display panel 21 are colored red or yellow, respectively. You may display in red or yellow.

  The emission colors of the first light source 90 of the first display 10 and the emission sources 92a, 92b, and 92c of the second display 20 are all the same white color or the same system color. As a result, the display colors of the first display 10 and the second display 20 are the same or the same system color, and even when the first display 10 and the second display 20 are arranged adjacent to each other, the respective colors are unified. Good looking.

  Further, when the first display 10 and the second display 20 have different visual luminances (display luminances), the light emission intensity of the light emission sources 92a, 92b, and 92c is adjusted by the adjusting means described above, and the first display 10 and The visual luminance of the second display device 20 can be adjusted to the same level. Thereby, the visual brightness of the entire display device 100 can be unified and the sense of unity can be increased.

  Instead of adjusting the emission intensity of the emission sources 92a, 92b, 92c, the emission intensity of the first light source 90 of the first display 10 may be adjusted. That is, it is only necessary to adjust the light emission intensity of at least one of the light emission sources 92a, 92b, and 92c and the first light source 90.

  As shown in FIGS. 2A and 2B, a partition is formed on the second control board 52 so as to surround the second light source 92 from the second control board 52 toward the second display panel 21. Plates (second partition plates) 72 and 72a are provided upright. The partition plate 72 is also provided in parallel to the second control board 52 at a position spaced from the second control board 52. The partition plates 72 and 72 a are reflection plates for reflecting light from the light emission sources 92 a, 92 b, and 92 c and directing the light toward the second display plate 21. The partition plate 72a is a partition plate provided on the first display 10 side, and the partition plate 72 is a partition plate provided in other portions. The upper end of the partition plate 72 a is not in contact with any of the second light transmitting substrate 32, the first display plate 11, and the second display plate 21. In other words, the height of the partition plate 72a from the second control board 52 is lower than the height of the first display board 11 and the second display board 21 from the second control board 52. Here, “height” has the same meaning as described above.

  The partition plate 62a of the first display 10 and the partition plate 72a of the second display 20 are formed adjacent to and in contact with each other. As described above, the upper end of the partition plate 62 a is not in contact with any of the first light transmitting substrate 31, the first display plate 11, and the second display plate 21. That is, as shown in FIG. 4B, a gap 63 is vacant on the partition plate 62a. The gap 63 is a gap for allowing the light L1 from the first light source 90 and the light guide 80 to reach the adjacent second display panel 21.

  As described above, the upper end of the partition plate 72 a is not in contact with any of the second light transmitting substrate 32, the first display plate 11, and the second display plate 21. That is, as shown in FIG. 4B, a gap 73 is vacant on the partition plate 72a. The gap 73 is a gap for allowing the light L2 from the light emitting sources 92a, 92b, and 92c to reach the adjacent first display panel 11.

  With the configuration as described above, the light from the first light source 90 and the light guide 80 passes through the gaps 63 and 73 formed in the upper part of the partition plate 62a and the partition plate 72a, and the end portion of the second display plate 21. Irradiate. In addition, light from the light emitting sources 92a, 92b, and 92c irradiates the end portion of the first display plate 11 through gaps 63 and 73 formed on the upper portions of the partition plate 62a and the partition plate 72a. In addition, the height of the partition plate 62a and the partition plate 72a or the size of the gaps 63 and 73 is determined by the arrangement of the first light source 90 and the light emission sources 92a, 92b, and 92c, the first display plate 11 and the second display plate 21. It can set suitably according to arrangement | positioning etc.

  In the first embodiment, the partition plate 62a and the partition plate 72a are formed adjacent to each other in contact with each other. In this case, the partition plate 62a and the partition plate 72a may be collectively formed as one partition plate. Then, the height of the upper end of the partition plate from the first control board 51 (or the second control board 52) is set to the first control board 51 (or the second control board) of the first display board 11 and the second display board 21. What is necessary is just to comprise below the height from 52).

  Note that the upper end portion of the partition plate 62 may or may not be in contact with the first light-transmitting substrate 31 or the first display plate 11. Further, the upper end portion of the partition plate 72 may or may not be in contact with the second translucent substrate 32 or the second display plate 21.

  As shown in FIGS. 2 (a) and 3 (b), the first warning light for the first warning light is directed from the second control board 52 to the second display board 21 on the four surrounding surfaces of the first warning light emission source 94. The light guide tube portion 74 is erected. The light guide tube portion 74 is provided up to a height in contact with the second display plate 21 (if the diffusion layer 24 is provided, the diffusion layer 24 provided on the surface of the second display plate 21 as shown in FIG. 4A). It has been. This is to prevent the light from the light source 94 for the first warning lamp from leaking out of the light guide tube portion 74, and to illuminate only the first warning display 27 to brighten it.

  Similarly, on the four surrounding surfaces of the second warning light source 96, as shown in FIG. 2A, the second warning light is guided from the second control board 52 toward the second display panel 21. A cylindrical portion 76 is erected. The light guide tube portion 76 is provided up to a height in contact with the second display plate 21 (if the diffusion layer 24 is provided, the diffusion layer 24 provided on the surface of the second display plate 21 as shown in FIG. 4A). It has been. This is because the light from the light source 96 for the second warning lamp is prevented from leaking outside the light guide tube portion 76, and only the second warning display 28 is illuminated and brightened.

  As described above, the first warning light emission source 94 and the second warning light emission source 96 emit red light or yellow light for warning, unlike the white light of the light emission sources 92a, 92b, and 92c. The first warning light emission source 94 and the second warning light emission source 96 can emit light independently of the light emission sources 92a, 92b, and 92c. The first warning light emission source 94 and the second warning light emission source 96 can emit light independently of each other.

  The first warning light emission source 94 and the second warning light emission source 96 may be light emission sources capable of adjusting the color tone from white light to yellow light to red light. By changing the first warning display 27 and the second warning display 28 of the second display board 21 by adjusting the color tone of the first warning light emission source 94 and the second warning light emission source 96. The present invention can be applied in common to many kinds of second indicators 20 having various warning lights.

(effect)
In the display device 100 having the above configuration, the gap 63 is provided above the partition plate 62a, and the gap 73 is provided above the partition plate 72a. Therefore, the light from the light emitting sources 92a, 92b, and 92c irradiates the end portion of the first display plate 11 through the gaps 63 and 73 at the upper part of the partition plate 62a and the partition plate 72a. Further, the light from the first light source 90 irradiates the end portion of the second display panel 21 through the gaps 63 and 73 at the upper part of the partition plate 62a and the partition plate 72a. Therefore, in the display device 100 in which the first display 10 and the second display 20 of different display methods are arranged adjacent to each other, the backlight light in the vicinity of the boundary between the first display 10 and the second display 20 Are mixed and uniform, and the boundary is not noticeable. Furthermore, when the first light source 90 and the light emitting sources 92a, 92b, and 92c emit light in the same color or the same color, the backlight light becomes uniform in the same color or the same color, and the boundary is not noticeable.

  In addition, if the display light intensities of the first display plate 11 and the second display plate 21 are different, a difference in visual luminance (display luminance) may be conspicuous even if the color tone is the same. In that case, the light emission intensity of either the first light source 90 or the light sources 92a, 92b, and 92c can be adjusted so that the visual luminance becomes the same level. Thereby, the sense of incongruity due to the difference in visual luminance becomes inconspicuous. At this time, only the light emission intensity of the light source closer to the boundary between the first display 10 and the second display 20 may be adjustable.

  The above-described feature is that, for example, the first display 10 including the first display panel 11 in which the display device 100 is active (relatively expensive) and the second display including the second display panel 21 that is passive (relatively inexpensive). Even in the display device 100 in which the display devices 20 having different structures, ie, the display devices 20, are adjacent to each other, the boundary between the first display device 10 and the second display device 20 is made inconspicuous, and the display device 100 displays a unified display. It is excellent in that it can be.

  Further, since the first warning light emission source 94 and the second warning light emission source 96 are provided independently of the light emission sources 92a, 92b, 92c, the first warning display is performed using the light emission sources 92a, 92b, 92c. 27, the first warning display 27 and the second warning display 28 can be displayed brighter than when the second warning display 28 is illuminated. In addition, since light guide tube portions 74 and 76 for the first warning light emission source 94 and the second warning light emission source 96 are provided to prevent light from leaking, it is possible to display more clearly. it can.

(Modification 1)
In the first embodiment, as shown in FIG. 4A, the upper end portion of the light guide tube portion 74 is in contact with the diffusion layer 24. However, as shown in FIG. 5, the diffusion layer 24 at a position facing the first warning light emission source 94 is partially eliminated so that the upper end portion of the light guide tube portion 74 is in direct contact with the second display panel 21. Also good. In the configuration shown in FIG. 4A, an effect is obtained that the entire second display panel 21 appears to be uniformly dark when the light emitting sources 92a, 92b, and 92c are not lit. However, as shown in FIG. 5, by illuminating the light without passing through the diffusion layer 24, it is possible to further increase the display brightness when the first warning display 27 is emitted. This configuration can be similarly applied to the second warning light emission source 96.

  It is not necessary to provide both or either of the first warning light emission source 94 and the second warning light emission source 96. The light guide tube portions 74 and 76 may not be provided in the first warning light emission source 94 and the second warning light emission source 96, respectively.

(Modification 2)
In the first embodiment, the partition plate 62a and the partition plate 72a are formed adjacent to and in contact with each other. However, as shown in FIG. 6, the partition plate 62a and the partition plate 72a may be separated from each other and adjacent to each other. The spaced intervals can be appropriately set according to the arrangement configuration of the first display plate 11 and the second display plate 21 and the first light source 90 and the second light source 92.

(Modification 3)
In the first embodiment, the first display 10 has a first light-transmitting substrate 31 and a first control substrate 51, and the second display 20 has a second light-transmitting substrate 32 and a second control substrate 52. have. However, as shown in FIG. 7, the first translucent substrate 31 and the second translucent substrate 32 may be combined to form one translucent substrate 38. In this case, the light shielding layers 36 and 37 may be combined to form one light shielding layer 36. Similarly, the first control board 51 and the second control board 52 may be combined and formed as one control board 53. This modification 3 has a simple configuration and can reduce the manufacturing cost.

(Other variations)
In the first embodiment, two displays, the first display 10 and the second display 20, are adjacent to each other. However, the number of indicators is not limited. Three or more displays may be adjacent to each other, and two adjacent displays may be configured as in the first embodiment (not shown). Further, a third indicator without a gap may be added between the partition plate and the display plate so as to be adjacent to each other (not shown).

  These indicators may use the same illumination method or may use different illumination methods. For example, the first display device may include a display plate with a built-in light source, and the second display device may be of a type in which the light source is arranged on a substrate. Moreover, you may adjoin the indicator using the same type of illumination system.

  Further, the non-reflective layer 33, the light shielding layers 36 and 37, and the diffusion layer 24 may not include any or all of them.

  In the first embodiment, each of the first light source 90 and the light emission sources 92a, 92b, and 92c is a light source that emits white light. However, the light source may emit light with another color tone or a different color tone. For example, if the first light source has the first color tone and the second light source has the second color tone, the boundary between the first display and the second display is displayed in an intermediate color between the first color tone and the second color tone. The In addition, either or both of the first light source and the second light source may be light sources capable of changing the color tone.

  In the first embodiment, the means for adjusting the emission intensity of the light emitting sources 92a, 92b, and 92c is provided, but the adjusting means may not be provided.
