Returning to FIGS. 2 and 3, on the second control board 52, the light emitting source for the first warning light (first light emitting source) 94 and the light emitting source for the second warning light (first light emitting source) shown in FIG. 2A are shown. ) 96, The light emitting source 92a (second light emitting source) shown in FIG. 2 (b), and the light emitting source 92b and the light emitting source 92c (both are second light emitting sources) shown in FIG. 3 (b) are arranged. The light emitting sources 92a, 92b, 92c, the light emitting source 94 for the first warning light, and the light emitting source 96 for the second warning light are collectively referred to as a second light source (second backlight light source) 92.

The light emitting sources 92a, 92b, and 92c are white LED backlight light sources for directly illuminating the second display plate 21 from the back surface, and a plurality of light emitting sources 92a, 92b, and 92c are arranged on the second control board 52. The light emitting sources 92a, 92b, and 92c are also arranged at positions not shown in FIGS. 2 and 3.

Further, an adjustment means (not shown) for adjusting the light emission intensity of the light emission sources 92a, 92b, and 92c is provided on the second control board 52. 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 extent when the display device 100 is assembled.

The light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light are red or yellow LEDs for individually illuminating the first warning display 27 and the second warning display 28 of the second display board 21. It is a light emitting source.

It may be displayed in red or yellow.

The light emitting colors of the first light source 90 of the first display 10 and the light emitting 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 become 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 color tones are unified. It looks good.

When the visible brightness (display brightness) of the first display 10 and the second display 20 is different, the light emission intensity of the light emitting sources 92a, 92b, and 92c is adjusted by the above-mentioned adjusting means, and the light emitting intensity is adjusted with the first display 10. The visible brightness of the second display 20 can be adjusted to the same extent. As a result, the visual brightness of the entire display device 100 can be unified and the sense of unity can be increased.

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

As shown in FIGS. 2A and 2B, a partition is placed 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 board 21. Plates (second partition plates) 72 and 72a are erected. Further, the partition plate 72 is also provided parallel to the second control board 52 at a position separated from the second control board 52. The partition plates 72 and 72a are reflectors for reflecting the light from the light emitting sources 92a, 92b and 92c 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 72a is not in contact with any of the second translucent 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 in contact with each other and adjacent to each other. As described above, the upper end of the partition plate 62a is not in contact with any of the first translucent substrate 31, the first display plate 11, and the second display plate 21. That is, as shown in FIG. 4B, there is a gap 63 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 plate 21.

Further, as described above, the upper end of the partition plate 72a is not in contact with any of the second translucent substrate 32, the first display plate 11, and the second display plate 21. That is, as shown in FIG. 4B, there is a gap 73 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 plate 11.

With the above configuration, 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. Further, the light from the light emitting sources 92a, 92b, 92c irradiates the end portion of the first display plate 11 through the gaps 63 and 73 formed in the upper part of the partition plate 62a and the partition plate 72a. 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 emitting sources 92a, 92b and 92c, and the arrangement of the first display plate 11 and the second display plate 21. It can be set as appropriate according to the arrangement and the like.

In the first embodiment, the partition plate 62a and the partition plate 72a are formed in contact with each other and adjacent to each other. In this case, the partition plate 62a and the partition plate 72a may be combined to form one partition plate. Then, the height from the first control board 51 (or the second control board 52) at the upper end of the partition plate is set to the height of the first control board 51 (or the second control board 52) of the first display board 11 and the second display board 21. It may be configured to be lower than the height from 52).

The upper end of the partition plate 62 may or may not be in contact with the first translucent 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), for the first warning light from the second control board 52 toward the second display board 21 on the four peripheral surfaces of the light emitting source 94 for the first warning light. The light guide tube portion 74 of the above is erected. The light guide tube portion 74 is provided up to a height in contact with the second display plate 21 (when 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). Has been done. This is to prevent the light from the light emitting source 94 for the first warning light from leaking to the outside of the light guide tube portion 74, and to illuminate only the first warning display 27 to make it shine brightly.

Similarly, as shown in FIG. 2A, the light guides for the second warning light are provided on the four peripheral surfaces of the light emitting source 96 for the second warning light from the second control board 52 toward the second display board 21. The tubular portion 76 is erected. The light guide tube portion 76 is provided up to a height in contact with the second display plate 21 (when 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). Has been done. This is to prevent the light from the light emitting source 96 for the second warning light from leaking to the outside of the light guide tube portion 76, and to illuminate only the second warning display 28 to make it shine brightly.

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

The light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light may be light emitting sources whose color tone can be adjusted from white light to yellow light to red light. By configuring the color tones of the light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light to be adjustable, the first warning display 27 and the second warning display 28 of the second display board 21 can be changed. , Can be applied in common to many types of second indicators 20 having various warning lights.

(effect)
The display device 100 having the above configuration is provided with a gap 63 above the partition plate 62a and a gap 73 above the partition plate 72a. Therefore, the light from the light emitting sources 92a, 92b, 92c passes through the gaps 63 and 73 above the partition plate 62a and the partition plate 72a and irradiates the end portion of the first display plate 11. Further, the light from the first light source 90 passes through the gaps 63 and 73 above the partition plate 62a and the partition plate 72a and irradiates the end portion of the second display plate 21. 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 near the boundary between the first display 10 and the second display 20 Are mixed and become uniform, and the boundaries are not noticeable. Further, when the first light source 90 and the light emitting sources 92a, 92b, 92c emit light in the same color or the same system color, the backlight light becomes uniform in the same color or the same system color, and the boundary is not conspicuous.

Further, if the intensity of the display light of the first display board 11 and the second display board 21 is different, the difference in the visible luminance (display luminance) may be conspicuous even if the color tone is the same. In that case, the emission intensity of any of the first light source 90 or the emission sources 92a, 92b, and 92c can be adjusted so that the visible brightness becomes the same. As a result, the sense of discomfort due to the difference in visible brightness becomes less noticeable. At this time, only the 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-mentioned features are, for example, a first display 10 including a first display board 11 in which the display device 100 is active (relatively expensive), and a second display including a passive (relatively inexpensive) second display board 21. Even in the display device 100 in which display devices having different configurations called the device 20 are adjacent to each other, the boundary between the first display device 10 and the second display device 20 is made inconspicuous, and a unified display is performed as the display device 100. It is excellent in that it can be done.

Further, since the light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light are provided independently of the light emitting sources 92a, 92b, 92c, the first warning display is displayed using the light emitting sources 92a, 92b, 92c. 27, The first warning display 27 and the second warning display 28 can be displayed brighter than the case where the second warning display 28 is illuminated. Further, since the light guide cylinders 74 and 76 for the light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light are provided respectively to suppress the leakage of light, the light can be displayed more clearly. it can.

May be good. In the configuration shown in FIG. 4A, when the light emitting sources 92a, 92b, and 92c are not lit, the effect that the entire second display board 21 looks uniformly dark can be obtained. However, as shown in FIG. 5, by illuminating without passing through the diffusion layer 24, the effect that the display brightness of the first warning display 27 at the time of light emission can be further increased can be obtained. This configuration is also applicable to the light emitting source 96 for the second warning light.

It is not necessary to provide both or either of the light emitting source 94 for the first warning light and the light emitting source 96 for the second warning light.
