BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device for a vehicle, and is most suitable for use in an automobile, for example.

In the conventional display device for automobiles, a black printing process is performed on the surface of the instrument panel made of a transparent substrate except for each warning mark, and the light source is disposed at a position corresponding to the warning mark on the back of the instrument panel. Each warning mark may be light-emitted by being transmitted through the light from the corresponding light source. (See, for example, Japanese Patent Application Laid-Open No. 2002-244595).

Although there is no description regarding the display color of each warning mark in the above-mentioned patent document, for example, if a translucent colored layer is provided on the warning mark on the surface of the instrument panel or on the rear side, and an incandescent lamp is used as a light source, each warning The display marks are light-emitted and displayed in the color of the transmissive colored layer provided respectively.

In addition, if the warning mark on the instrument panel is made transparent, or if a light-transmissive bright color is prepared on the surface or the back of the instrument panel, or a light emitting diode of a predetermined luminous color is adopted as a light source thereon, each warning mark corresponds to each. One light emitting diode is displayed in the color of light emission.

However, in the vehicle display device described above, even when the light source is turned off, that is, there is no abnormality in each part of the vehicle, and the warning mark is not illuminated, the shape of the warning mark can be clearly seen by the driver. have.

Accordingly, the driver must visually see the shape of the warning display mark that does not cause a problem even if the driver does not look in a good relationship with various instruments that are always displayed on the instrument panel, thereby reducing the sharpness of the display device for a vehicle.

In order to solve this problem, a smoke print layer (transparent and low light transmittance) is provided on the instrument panel warning mark portion.

In this case, in the case where the warning display mark is not light-emitting, the visibility of the shape of the warning display mark can be reduced, but it is not to be made completely invisible.

Accordingly, the present invention has been made with reference to these points, and the object thereof is to assemble the study of the instrument panel configuration, and to clearly display the indicator, which is a warning display mark that is displayed by luminescence, so that its shape is not visible when it is a non-luminescence display. It is to provide a vehicle display device that stands out.

The present invention employs the following technical means to achieve the above object.

The vehicle display device according to claim 1 of the present invention is characterized in that the light emitting diode is formed in the same color as the light emitting color of the light emitting diode by light transmitted from the light emitting diode disposed on the face of the face and the face, and the light emitting diode formed in the face. An indicator was provided, and a light-transmissive colored layer was formed on the front surface of the face, including an indicator, and a light-shielding colored layer was removed from the face of the face.

Therefore, when the indicator light emitting display LED is turned off, the face is irradiated with external light incident on the face from the outside so that the entire face of the face is uniformly recognized by the color of the transparent colored layer. .

In other words, the indicator shape is invisible on the face of the face.

Therefore, when the indicator is non-luminescent display, the shape of the vehicle can be provided so that the shape thereof is not seen, so that the indicator can be clearly seen.

In the vehicular display device according to the second aspect of the present invention, a light emitting diode disposed on the back of the face and a face made of a light-transmissive material, and transmitted light from a light emitting diode formed on the face, are emitted and displayed in the same color as the light emitting color of the light emitting diode. An indicator was provided, and the light-shielding colored layer which removed the indicator was provided in the front surface of the face, and it was comprised so that the light-transmitting colored layer of the same color as the electro-shielding colored layer may be made as if it covered the indicator.

When the light emitting diode for the indicator light emitting display is turned off, the face is irradiated by external light incident on the face from the outside and recognized by the eye.

At this time, the boundary between the two sides is not clear because it is the same color as the light-shielding colored layer formed on the face background and the light-transmitting colored layer covering the indicator.

Therefore, the whole face surface is recognized uniformly as the light-shielding colored layer color.

That is, the indicator shape is invisible on the face of the face.

Accordingly, when the indicator is in non-luminescent display, the shape of the indicator is not visible so that a vehicle display apparatus having a clear field of view can be provided.

By the way, although the light-shielding colored layer and the translucent colored layer are the same color, since the containing component etc. are different, they may differ in color, lightness, saturation, etc., or the surface precision of both may differ.

At this time, there is a possibility that the boundary between both sides becomes discernible to the driver.

In this case, like the vehicle display device described in claim 3 of the present invention, a light transmittance adjusting member is disposed in front of the face, that is, on the driver's seat side, so as to cover the face, and the face is made visible through these light transmittance adjusting means. With the configuration to be recognized, the external light is reduced in the reflected light intensity from the face of the face toward the driver's recognition direction so that the boundary between the light-shielding colored layer and the light-transmitting colored layer is less noticeable or hardly recognized. can do.

In addition, if the vehicle display apparatus light transmittance adjusting member described in claim 4 of the present invention is constituted by a smoke lens, the desired light transmittance can be easily obtained.

The vehicle display apparatus according to claim 5 of the present invention has a configuration in which a plurality of indicators are provided.

Accordingly, as more information displayed on the face is displayed, a vehicle display apparatus having a clear field of view can be provided.

In the vehicular display device according to claim 6 of the present invention, the light emitting color of the light emitting diode is composed of a plurality of types.

 Therefore, for example, the display color of the indicator can be separately used in accordance with the level of importance of the abnormality, so that the driver can recognize the degree of abnormality not only by lighting but also by the display color.

The magnitude of the drive current at the time of light-emitting diode lighting of the display device for vehicles described in Claim 7 of this invention is set so that it may become large so that the wavelength of the light emission color of a light-emitting diode may become farther from the wavelength of the translucent colored layer made in the face. I did.

Here, the brightness of the light from the light emitting diode that has passed through the translucent colored layer, that is, the transmitted light, will be described.

In the case where the light emitted from the light emitting diode is transmitted through the light-transmitting colored layer, if the light-emitting luminance of the light-emitting diode is the same, the transmittance luminance when the wavelength of the light-emitting color of the light-emitting diode is close to the wavelength of the color of the light-transmitting colored layer is obtained. The wavelength is higher than the luminance of the transmitted light when the wavelength is separated from the wavelength of the color of the transparent colored layer.

For example, the transmissive luminance when the transmissive colored layer is orange (610 nm) and the light emitting diode is red (660 nm) or yellow (590 nm) is higher than the transmissive luminance when the light emitting color of the light emitting diode is green (525 nm). .

In this case, in order to make the luminance of the transmitted light of the green light emitting diode equal to the luminance of the transmitted light of the red light emitting diode or the yellow light emitting diode, a method of increasing the emission luminance of the green light emitting diode, for example, a driving current value of the green light emitting diode may be increased.

Therefore, when the size of the driving current at the time of light-emitting diode is set so that the wavelength of the light-emitting color of a light emitting diode will become large away from the wavelength of a light-transmissive colored layer color, the light from a plurality of light-emitting diodes with a different light-emitting color will pass through a light-transmissive colored layer. In this case, since the luminance of each transmitted light can be made almost the same, a vehicle display apparatus having good recognition can be realized.

Hereinafter, a case in which the display device for a vehicle according to the present invention is applied to the combination meter 1 mounted on an automobile will be described based on the drawings.

(1st embodiment)

 1 is a front view of the combination meter 1 according to the first embodiment of the present invention.

In FIG. 1, the vertical direction is the vertical direction of the vehicle.

1 shows light emission display states of the indicators 2c, 2d, and 2e.

FIG. 2 is a partial cross-sectional view of the combination meter 1 according to the first embodiment of the present invention, and is a cross-sectional view taken along the line II of FIG. 1.

In Fig. 2, the upward direction belongs to the driver's seat.

FIG. 3 is a cross-sectional view of the combination meter 1 according to the first embodiment of the present invention, and is a cross-sectional view along the line II-II of FIG. 1.

In Fig. 3, the left side belongs to the driver's seat side.

4 is an explanatory diagram for explaining an electric circuit configuration of the combination meter 1 according to the first embodiment of the present invention.

The combination meter 1, which is a vehicle display device, displays information about the vehicle, which is arranged in front of the driver's seat.

The combination meter 1 which concerns on the 1st Embodiment of this invention forms the speedometer which instruct | indicates the vehicle traveling speed as shown in FIG.

The combination meter 1 is provided with a face 2 for displaying the information and recognizing the driver, and the driver can recognize it with his eyes.

As shown in Fig. 1, the dial 2 has a scale portion 2a and a character portion 2b as a speedometer, an ABS indicator 2c as an indicator, a non-seat indicator 2d as a indicator, and a photogram lighting indicator 2e. have.

The ABS indicator 2c lights up when an abnormality occurs in the ABS (anti-lock brake system).

In addition, the seat belt non-wearing indicator 2d lights up when the driver's seat driver is seated in the driver's seat when the seat belt is in a non-wearing state.

In addition, the formgram lighting indicator 2e lights up while the formgram of the said vehicle is lighting.

The dial 2 makes a transparent colored layer 21 on the front surface (left surface of FIG. 3, driver's side surface) of the transparent sheet 20 made of a translucent material, for example, a polycarbonate resin or the like. The light-shielding colored layer 22 is formed on the back surface (right side surface of FIG. 3) of the transparent sheet 20. As shown in FIG.

That is, the scale portion 2a and the character portion 2b are allowed to transmit light (for example, while being transparent) on the entire front surface of the transparent sheet 20, as shown in FIG. The translucent colored layer 21 is made in the background parts other than 2a) and the character part 2b by printing or a hot stamp.

In the combination meter 1 which concerns on 1st Embodiment of this invention, the translucent colored layer 21 is formed in vermilion.

On the other hand, a part of the rear surface of the transparent sheet 20, that is, the portion downward from the oblique line D in FIG. 1, as shown in FIG. 2, is provided with a light-shielding colored layer on a background portion other than the indicators 2c, 2d, and 2e. 22) is made by printing or hot stamp etc.

That is, each indicator 2c, 2d, and 2e is formed in the state which is the surface of the transparent sheet 20 which does not produce the light-shielding colored layer 22 in the part shown in black in FIG. .

In the combination meter 1 which concerns on the 1st Embodiment of this invention, the light-shielding colored layer 22 is formed in black, removing glossiness.

That is, each of the indicators 2c, 2d, and 2e in the face 2 is formed uncolored on the back side of the face 2 (as shown in the lower part of FIG. 2), and the surface side of the face 2 ( In the upper part of Fig. 2, a translucent colored layer 21 is formed so as to cover the indicators 2c, 2d and 2e.

Therefore, when the driver sees the face 2, when the indicators 2c, 2d and 2e do not display light emission, the indicators 2c, 2d and 2e are blocked by the translucent colored layer 21 and the eyes are closed. Is not recognized.

Moreover, as shown in FIG. 3, the through hole 2f for making the shaft 6a of the drive part 6 mentioned later is made in the center part of the face 2 is made.

Behind the face 2, a light emitting diode, which is a light source for emitting light of each of the indicators 2c, 2d, and 2e, is arranged corresponding to each of the indicators 2c, 2d, and 2e, as shown in FIG.

That is, in response to the ABS indicator 2c, the orange diode 10 corresponds to the seat belt non-wear indicator 2d, and the red light emitting diode 11 corresponds to the photogram lighting indicator 2e. ) Are arranged respectively.

Each light emitting diode 10, 11, 12 is mounted on a printed board 5 disposed behind the light guide plate 3 (lower in FIG. 2) as shown in FIG.

In addition, a light shielding frame 14 is formed between the character board 2 and the printed board 5 as shown in FIGS. 1 and 2.

The light shielding frame 14 individually receives each of the light emitting diodes 10, 11, 12 formed on the cross-sectional legs, such as resin or metal, and the light emitted from each of the light emitting diodes 10, 11, 12 corresponds to each of them. Irradiation other than the indicators 2c, 2d, and 2e is prevented.

Since the light shielding frame 14 is attached to both the face 2 and the printed board 5 in close contact with each other, a good light leakage suppressing effect can be obtained.

In the light shielding frame 14, a light guide 13 formed of a transparent acrylic resin, for example, is disposed as a transparent material.

The light guide 13 is for illuminating the light from each light emitting diode 10, 11, 12 with the respective indicators 2c, 2d and 2e with high efficiency.

On the back of the face 2, the light guide plate 3 is arranged to overlap the face 2 as shown in FIG. 3.

In addition, the light emitting diode 4 is arranged to allow light to enter the light guide plate 3.

The light guide plate 3 is formed in plate shape, such as a translucent material, for example, a transparent polycarbonate resin.

The planar shape of the light guide plate 3 completely covers the upper part than the oblique line D of FIG. 1 of the face 2, and does not overlap with the light blocking frame 14 indicated by the broken line in FIG. It is formed in the shape of.

The light guide plate 3 emits light in the state where the surface of the face 2 faces as the light is introduced from the light emitting diode 4.

The light guide plate 3 itself and the positional relationship between the light guide 9 and the light emitting diode 4 are adjusted so that the illuminance of the light emitting surface is uniform throughout the light emitting surface.

Therefore, when the light emitting diode 4 is turned on, the dial 2 is displayed with the scale 2a and the character 2b emitting light in the color of the fermentation, for example, white, and the scale 2a and the character ( 2b) The surrounding background portion is displayed in luminescent uniform brightness.

However, the portion below the oblique line D in FIG. 1 of the face 2 is not light-emitting due to the light-shielding colored layer on the back side of the face 2.

In addition, the indicators 2c, 2d, and 2e do not display light emission in the same way because light irradiation from the outside is suppressed by the light shielding frame 14.

On the back surface of the face 2, the printed board 5 which comprises the electrical circuit part of the combination meter 1 is arrange | positioned by 1st Embodiment of this invention.

The printed board 5 is made of, for example, a glass epoxy board or the like.

The orange light emitting diode 10, the red light emitting diode 11, the green light emitting diode 12 and the light emitting diode 4 described above are mounted on the printed board 5.

In addition, on the printed board 5, as shown in FIG. 3, the light emitting diode 8 which is a light source for emitting light of the guideline 7 described later is mounted.

In the printed board 5, a light guide 9 is provided at a position corresponding to the light emitting diode 8 so that the light from which the light emitting diode 8 emits light is incident on the guide 7.

The light guide 9 is formed of a light-transmissive material, for example, a transparent polycarbonate resin, like the light guide plate 3.

In addition, as shown in FIG. 3, on the printed board 5, the shaft 6a which is a guide shaft by an angle corresponding to an electric signal from the outside (in the combination meter 1 according to the first embodiment of the present invention) is a speed. It is attached and fixed by the drive part 6 which is a rotating machine which rotates.

The printed circuit board 5 also has the indicators 2c, 2d, and 2e for displaying the orange light emitting diodes 10, the red light emitting diodes 11, and the green light emitting diodes 12; The control circuit 16 which controls the lighting / lighting-off of the light emitting diode 4 of the light emitting diode 4 and the instruction | indication 7, and drives the drive part 6 is equipped.

The control circuit 16 is composed of a microcomputer or the like.

 The driving unit 6 of the rotating machine is composed of, for example, a cross-coiled actuator (a driving device that converts energy into rotational motion by hydraulic or electric motor), a stepping motor, or the like, and responds to electric signals from the outside. The shaft 6a, which is the guide shaft, is rotated by an angle.

The shaft 6a of the drive part 6 passes through the through hole 2f of the dial 2 and emerges from the front direction, that is, from the left side of FIG. 3, and the guide 7 is fixed at the end thereof.

The guideline 7 is made of a translucent material acrylic resin or the like, and has a diffuse reflection layer (not shown) on the lower surface, that is, the surface opposite to the driver.

For example, a time signal surface (a kind of metal micromachining for forming a film on the metal surface) or a coated surface is formed.

Accordingly, the guideline 7 displays light emitted from the light emitting diode 8 incident on the guideline 7 by the light guide 9 by reflecting the light on the diffuse reflection layer described above.

In addition, the light shielding cap 15 is attached to the instruction | indication 7.

The light shielding cap 15 is formed of a resin or metal plate having light shielding properties, and prevents light from the light emitting diodes 8 from directly entering the driver's eyes.

The dial 2, the light guide plate 3, the printed board 5, the driving unit 6, and the like described above are housed in the case 17.

In addition, the transparent cover 19 is mounted on the surface of the face 2 via a frame-shaped paper plate 18.

The transparent cover 19 is formed of a thin plate or glass plate of transparent resin.

Next, an electric circuit configuration and operation of the combination meter 1 according to the first embodiment of the present invention described above will be described based on FIG. 4.

As shown in FIG. 4, power is always supplied from the battery 31 to the control circuit 16.

In addition, the ignition switch 30 is connected to the control circuit 16 so that the operation state (ON or OFF) can be detected.

The control circuit 16 is connected to a speed sensor 32 that detects the traveling speed of the vehicle so that a detection signal can be input.

In addition, the control circuit 16 is connected to the ABS system controller 33 that controls the ABS system of the vehicle so as to detect the operation state thereof.

The control circuit 16 is connected to a seat belt wearing sensor 34 for detecting a seat belt wearing state of the vehicle so as to input a detection signal.

In addition, the fog lamp switch 35 of the vehicle is connected to the control circuit 16 so as to detect its operating state (ON or OFF).

In addition, the control circuit 16 includes an orange light emitting diode 10, a red light emitting diode 11, and green, which are driven based on detection signals from the various sensors, switches 30, 32, 33, 34, and 35 described above. The light emitting diode 12, the light emitting diodes 4 and 8, and the drive part 6 are connected.

When the ignition switch 30 is turned on by the driver and the vehicle is in an operating state, the control circuit 16 detects that the ignition switch 30 is in the ON state and turns on the light emitting diodes 4 and 8.

Accordingly, the scale 2a and the character 2b are transmitted through the light from the light-emitting diode 4 and displayed on the dial 2, and the guide 7 is applied to the light from the light-emitting diode 8 at the same time. Luminous display.

Further, the control circuit 16 drives the drive unit 6 based on the detection signal from the speed sensor 32 to rotate the shaft 6a to a predetermined angle, that is, an angle indicating the traveling speed of the vehicle.

Next, the recognition state by the eye of the face 2 and the indicators 2c, 2d, and 2e, which are the features of the combination meter 1 according to the first embodiment of the present invention, will be described.

(A) When the indicators 2c, 2d, and 2e do not all emit light.

In this case, in the dial 2, the scale 2a and the letter 2b are displayed in white, and the upper part of the background part in the diagonal line D of FIG.

Further, the downward portion from the oblique line D of FIG. 1 of the background portion does not emit light, and is irradiated with external light, so that it is recognized as darker scarlet than the upward portion of the diagonal line D of FIG.

In addition, since the orange light emitting diode 10, the red light emitting diode 11, and the green light emitting diode 12 are not all lit, the indicators 2c, 2d, and 2e on the face 2 are not completely recognized.

In other words, it is recognized that the indicators 2c, 2d, and 2e do not exist on the character board 2 themselves.

In the conventional vehicle display apparatus, the indicator is formed by removing the indicator on the front face of the face and making a colored layer or a method of making a semi-transparent colored layer having a color different from that of the indicator background.

In this case, the shape of the indicator can be reliably recognized by the driver even when the light source for the indicator light emission display is turned off.

In other words, at that point, even a figure that is not required to be recognized by the driver is seen, and there is a problem that the sharpness of the face decreases.

On the other hand, in the combination meter 1 according to the first embodiment of the present invention, as described above, it is possible to completely hide the unnecessary indicators 2c, 2d, and 2e from the face 2, and thus a combination meter having a clear field of view. (1) can be realized.

(B) When the indicators 2c, 2d, and 2e all display light emission.

If an abnormality occurs in the ABS system during operation of the vehicle, the control circuit 16 of the combination meter 1 receives the abnormality signal from the ABS system controller 33 and turns on the orange light emitting diode 10.

Therefore, the ABC indicator 2c is displayed in orange on the face 2.

When the driver is not wearing the seat belt while the vehicle is in operation, the control circuit 16 turns on the red light emitting diode 11 based on the detection signal from the seat belt wearing sensor 34.

As a result, the seat belt non-wear indicator 2d is displayed in red on the face 2.

When the driver operates the fog lamp switch 35 to turn on the fog lamp (not shown) during the operation of the vehicle, the control circuit 16 detects this and turns on the green light emitting diode 12.

Thus, the program indicator 2e is displayed in green on the face 2.

That is, each of the indicators 2c, 2d, and 2e is displayed by the emission color of the corresponding light emitting diodes 10, 11, and 12 in the scarlet background on the face 2, so that the driver can recognize the eyes. .

By the way, in the combination meter 1 which concerns on the 1st Embodiment of this invention, the translucent colored layer 21 of the face 2 is vermilion, and the wavelength is about 600 nm.

On the other hand, the light emission color wavelength of the orange light emitting diode 10 for the ABS indicator 2c is about 590 nm, and the light emission color wavelength of the red light emitting diode 11 for the seat belt non-wearing indicator 2d is about 620 nm, and the green for the photogram indicator 2e is green. The light emission color wavelength of the light emitting diode 12 is about 525 nm.

Since the orange light emitting diodes 10 and the red light emitting diodes 11 have such a light emission color wavelength close to that of the translucent colored layer 21 of the face 2, the light from each light emitting diode 10, 11 has a high transmittance. It transmits through the translucent colored layer 21.

However, compared with the orange light emitting diode 10 and the red light emitting diode 11, the light emission color wavelength of the green light emitting diode 12 is far from the wavelength of the translucent colored layer 21 of the face 2.

Therefore, the light transmittance when the light from the green light emitting diode 12 passes through the translucent colored layer 21 of the face 2 is reduced by the case of the orange light emitting diode 10 and the red light emitting diode 11.

Therefore, when the driving current values of the light emitting diodes 10, 11, and 12 are the same, the light emission luminance of the fog lamp lighting indicator 2e is lower than that of the ABS indicator 2c and the seat belt non-wear indicator 2d. do.

Therefore, in the combination meter 1 which concerns on the 1st Embodiment of this invention, the green light emitting diode 12 which is the light emitting diode in which the emission color wavelength is far from the wavelength of the translucent colored layer 21 of the character board 2 in the control circuit 16 is carried out. ) Is set larger than the driving current values of the orange light emitting diode 10 and the red light emitting diode 11.

As a result, the brightness of the combination meter 1 can be improved by equalizing the light emission luminances of the three indicators 2c, 2d, and 2e.

(2nd embodiment)

5 is a front view of the combination meter 1 according to the second embodiment of the present invention.

FIG. 6 is a partial cross-sectional view of the combination meter 1 according to the second embodiment of the present invention, and is a cross-sectional view taken along the line VI-VI of FIG. 5.

The upward direction in FIG. 6 is a driver's seat side.

The combination meter 1 which concerns on 2nd Embodiment of this invention changes the structure of the character board 2 with respect to the combination meter 1 which concerns on 1st Embodiment of this invention.

That is, the scale 2a, the character 2b, and the indicators 2c, 2d, and 2e are transmitted through the front surface of the transparent sheet 20 (for example, in a transparent state) while the light is transmitted. The semi-shielding colored layer 23 is printed or hot stamped on the background portion other than the portion 2a, the character portion 2b, and the respective indicators 2c, 2d, and 2e.

In the combination meter 1 which concerns on 2nd Embodiment of this invention, the semi-shielding colored layer 23 is formed in scarlet.

In addition, as shown in Figs. 5 and 6 on the front surface of the transparent sheet 20, at least the indicators 2c, 2d, and 2e cover the same system color as that of the semi-shielding colored layer 23, i.e., scarlet semi-transparent The colored layer 24 is made.

In this case, the dial 2 is displayed on the dial 2a and the dial 2b by light from the light emitting diode 4 while the vehicle is in operation.

On the other hand, the background part which is a part other than the scale part 2a and the character part 2b of the character board 2 is irradiated with the external light from the exterior of the combination meter 1, and it is scarlet red which is the color of the semi-shielding colored layer 23. Is recognized.

In addition, the translucent colored layer 24 is similarly recognized as scarlet.

Also in the combination meter 1 according to the second embodiment of the present invention, as the dial 2 is configured as described above, the orange light emitting diode 10, the red light emitting diode 11, and the green light emitting diode 12 Is not lit, the indicators 2c, 2d, and 2e on the face 2 are not completely recognized, and the unnecessary indicators 2c, 2d, and 2e on the face 2 are not completely visible. Thus, the combination meter 1 having a clear field of view can be realized.
