Has been proposed (see Patent Document 1).
JP 2006-201038 A

  However, in the above-described conventional display device, since the entire decoration ring has translucency, there is a problem that the appearance of the display device tends to be monotonous with little change.

  The present invention has been made in view of the above-described problems, and an object of the present invention is to provide a display device having a novel appearance in a configuration including a decorative member that emits light on the front side of a display.

  In order to achieve the above object, the present invention employs the following technical means.

  The display device according to claim 1 of the present invention includes a display that forms various types of information as an image on a screen and displays the light emission, and a decorative member that is disposed on the front side of the display so as to overlap the display. The decorative member is formed in a shape related to the shape of the image, the decorative member is configured by combining a light transmitting portion and a light non-transmitting portion, and the design image portion is located on the display screen at a position corresponding to the light transmitting portion. It is formed, and the light from the design image part is transmitted through the light transmission part and emitted to the front side of the light transmission part, and is visually recognized.

  According to this configuration, the design image portion formed on the screen of the display is not directly recognized, but is made visible through the light transmitting portion of the decorative member. That is, the design image portion is visually recognized by protruding from the front side of the display screen. Furthermore, the decorative member is configured by combining a light transmissive portion and a light transmissive portion, that is, the light transmissive portion is disposed adjacent to the light transmissive portion. It plays an effect that makes it stand out more. As a result, the appearance of the display device can be made novel with enhanced stereoscopic effect.

  In the display device according to the second aspect of the present invention, the light transmitting portion is formed of a light transmitting material, the light transmitting portion is formed of a light transmitting material, and the light transmitting portion extends in the viewing direction of the display. A wall surface is provided, and the wall surface is in close contact with the light-impermeable member over substantially the entire surface.

  According to the above-described configuration, when the light non-transparent portion is in close contact with the wall surface of the light transmitting portion, the wall surface of the light transmitting portion functions as a mirror surface. Therefore, when the light from the design image portion of the display is incident on the light transmitting portion and travels through the light transmitting portion, if this light enters the wall surface of the light transmitting portion, it is reflected there because it is specular. Proceed through the light transmission section again. Therefore, the light from the design image part that has entered the light transmission part can be guided to the front side of the light transmission part with high efficiency. Thereby, the light emission brightness | luminance of a light transmissive part can be raised. Furthermore, according to the above-described configuration, the light from the design image portion can be guided to the front side of the light transmission portion with high efficiency, so that the height of the light transmission portion is maintained while maintaining the high light emission luminance of the light transmission portion. That is, the protrusion length from the display screen in the viewing direction can be increased. For example, even if the height of the light transmission part is such that the viewer cannot directly see the screen of the display device through the light transmission part, the light transmission part can be displayed with light emission with high light emission luminance. Thereby, the appearance of the display device can be made novel while enhancing the stereoscopic effect.

  The display device according to claim 3 of the present invention is characterized in that a diffuse reflection layer is provided on the front surface of the light transmission portion.

  If it is set as the above-mentioned composition, the light which progressed in the inside of a light transmission part and reached the front side surface of a light transmission part can be emitted in the wide direction outside a light transmission part by a diffuse reflection layer. Therefore, even if the viewer's posture changes, the light transmission part is always viewed brightly by the viewer. Thereby, the appearance of the display device can be made novel.

  The display device according to claim 4 of the present invention is characterized in that the light-impermeable portion is formed of an opaque material, and the light-transmitting portion is formed as a space surrounded by the light-impermeable portion.

  According to the above-described configuration, the light transmission part is formed as a space surrounded by the light non-transmission part, that is, an air layer. In this case, the light emitted from the design image portion of the display is repeatedly reflected on the wall surface of the light non-transmissive portion around the light transmissive portion, and is emitted from the decorative member. Therefore, an effect similar to that of the display device according to claim 1 can be obtained.

  The display device according to claim 5 of the present invention is characterized in that a light reflecting layer having a high light reflectance is formed on a wall surface of the light non-transmitting portion facing the light transmitting portion.

  If it is set as the above-mentioned composition, the light radiate | emitted from the design image part of the display can be guide | induced to the front side of a decoration member with high efficiency, and can be radiate | emitted, and the luminescent brightness of a decoration member can be raised.

  In the display device according to the sixth aspect of the present invention, the image includes an instruction graphic, and the instruction graphic indicates a change in the information indicated by the movement, and is a dotted pattern on the design image portion on the extension of the display graphic of the display. Alternatively, a high-luminance portion that is linear and has a higher luminance than the surroundings is formed, and the high-luminance portion moves in conjunction with the movement of the pointing graphic.

  According to the above-described configuration, the viewer visually recognizes both the movement of the instruction graphic that appears on the display screen and the movement of the high-luminance portion displayed on the light transmission portion in conjunction with the movement. Therefore, it is possible to improve the visibility of information indicated by the pointing graphic. At the same time, the appearance of the display device can be made novel by displaying the high luminance portion in addition to the instruction graphic.

  In the display device according to claim 7 of the present invention, the image of the display is a pointer instrument that indicates a physical quantity by the rotation angle position of the pointer, the indicating graphic is the pointer, and the decorative member is the rotation center of the pointer. It is characterized by being formed in a concentric annular shape and arranged at a position away from the tip of the pointer.

  With the above-described configuration, a high brightness portion is formed on the light transmitting portion away from the tip of the pointer and on the extension of the tip of the pointer, and this high brightness portion is integrated with the pointer in conjunction with the rotation of the pointer. Since it rotates as if it exists, the effect of the invention of claim 6 can be realized reliably.

  In this case, as in the display device according to claim 8 of the present invention, the design member made of a translucent material disposed adjacent to the inner peripheral side of the decorative member, and the interior of the design member from the end of the design member The design member is provided with a light source arranged so that light can be incident on the display member, and the display design of the pointer instrument is formed on the design member by reflecting light from the light source traveling in the design member. Thus, the appearance of the display design of the pointer instrument can be made novel.

  In the display device according to claim 9 of the present invention, the image of the display device is a navigation instruction display image of the navigation system, the instruction graphic is a navigation instruction arrow, the decorative member is formed outside the navigation instruction display image, and It is characterized by being arranged at a position away from the tip of the route direction arrow.

  With the above-described configuration, a high-luminance portion is formed on the light transmitting portion that is separated from the tip of the route indication arrow and on the extension of the tip of the route indication arrow, and this high-luminance portion is interlocked with the rotation of the route indication arrow. Since it rotates as if it is integral with the course instruction arrow, the effect of the invention of claim 6 can be realized with certainty.

  According to a tenth aspect of the present invention, the display device is a liquid crystal display device. Thereby, an image can be easily formed.

  Hereinafter, the case where the display device according to the present invention is applied to a combination meter 1 mounted on an automobile will be described as an example with reference to the drawings.

(First embodiment)
The combination meter 1 is arranged in the instrument panel in front of the driver's seat in the car interior, and forms information necessary for driving the car and information on the operating state of each part of the car on the screen 21 of the liquid crystal panel 2 as an image. This is what the driver sees. In the combination meter 1 according to the first embodiment of the present invention, as shown in FIG. 1, a speedometer S for instructing the traveling speed of the automobile and a navigation guide N for instructing a route to the destination are provided on the liquid crystal panel 2. An image is formed on the screen 21.

  Below, the structure of the combination meter 1 by 1st Embodiment of this invention is demonstrated.

  In the combination meter 1 according to the first embodiment of the present invention, a liquid crystal display is used as a display. Specifically, a TFT (Thin Film Transistor) type dot matrix type is used. As shown in FIG. 2, the liquid crystal panel 2 is transmitted and illuminated by a backlight (not shown) disposed behind it (right side of FIG. 2), and is lit and displayed. In the liquid crystal panel 2, the speedometer S and the navigation guide N described above are formed as images on the screen 21.

  First, the configuration of the speedometer S will be described.

  The speedometer S is formed as a pointer instrument. That is, as shown in FIG. 1, numerals 22, pointers 23 that are instruction figures, and characters 24 are formed on the screen 21 as images. Furthermore, the scale 31 which is a display design is formed in the scale ring 3 mentioned later which is a design member arrange | positioned on the liquid crystal panel 2 in piles. The pointer 23 is displayed by rotating around the virtual center C on the screen 21 corresponding to the traveling speed of the automobile. When the pointer 23 as an instruction graphic indicates the numeral 22 and the scale 31, the traveling speed is displayed. Here, as shown in FIG. 1, the numbers 22 are arranged radially along the same arc centered on the virtual center C.

  On the front side of the liquid crystal panel 2 (left side in FIG. 2), a scale ring 3 is disposed so as to overlap the liquid crystal panel 2. The scale ring 3 is made of a translucent material such as a colorless and transparent polycarbonate resin or acrylic resin. The scale ring 3 has a shape related to the shape of the speedometer S, that is, as shown in FIG. 1, is formed in an annular shape with a part cut off, and a virtual center C that is the rotation center of the pointer 23 on the liquid crystal panel 2. And are arranged on the same axis. As shown in FIG. 1, the scale ring 3 is disposed on the liquid crystal panel 2 at a position away from the tip of the pointer 23 formed on the screen 21 of the liquid crystal panel 2, that is, on the outer peripheral side of the pointer 23. . The scale ring 3 includes a scale 31 that is a display design of the speedometer S.

  The scale 31 is formed by providing an elongated recess on the back side (right side in FIG. 2) of the scale ring 3. As shown in FIG. 3, the cross-sectional shape of the concave portion as the scale 31 is an inverted V-shape, and is composed of two inclined surfaces 31a and 31b. The scale 31 is provided radially on the scale ring 3 with the virtual center C as the center. On both end faces 32 of the scale ring 3, light emitting diodes 4 as light sources are arranged so that light can enter the scale ring 3 respectively. As shown in FIG. 3, the light from the light emitting diode 4 traveling in the scale ring 3 is reflected by the inclined surfaces 31a and 31b and emitted from the scale ring 3 to the front side of the combination meter 1, that is, the driver side. This reflected light is visually recognized as a scale 31. The light from the light emitting diode 4 incident on the scale ring 3 from each end face 32 travels in the scale ring 3 while repeating reflection on each face of the scale ring 3 and reaches the vicinity of the opposite end face 32. In the meantime, it is incident on the slopes 31a and 31b in the middle and is reflected there. As a result, all the scales 31 provided on the scale ring 3 are lit and displayed with substantially the same brightness.

  Next, the configuration of the navigation guide N will be described.

  As shown in FIG. 1, the navigation guide N instructs a route to a destination by a route arrow 25 that is a pointing graphic formed as an image on the liquid crystal panel 2. When the car approaches the intersection, as shown in FIG. 1, a schematic diagram of the intersection is displayed, and the direction in which the vehicle should travel is displayed superimposed on the schematic diagram of the intersection. In the case of FIG. 1, the intersection is a five-way intersection, indicating that the direction in which the vehicle should travel is about 45 ° to the right. These displays are performed based on display signals from the navigation system device 14 mounted on the automobile. The navigation system device 14 is a known device that calculates the position of the vehicle based on a position signal from a satellite and a signal from a built-in inertial navigation device. When it is sufficient to proceed on the road that is currently running, the navigation guide N displays only the route arrow 25, and the route arrow 25 points upward in FIG.

  Next, the decorative ring 15 that is a decorative member disposed on the front side of the liquid crystal panel 2 will be described.

  As a whole, the decorative member 15 is formed in a circular arc shape coaxial with the scale ring 3 as shown in FIG. Similarly to the scale ring 3, the decorative member 15 is arranged in close contact with the surface of the liquid crystal panel 2 as shown in FIG. 2. The decorative member 15 is arranged in order from the scale ring 3 side toward the outer peripheral side thereof, a trim ring 15b that is a light opaque portion, a transparent ring 15a that is a light transparent portion, and a trim ring 15c that is a light opaque portion. It is configured to be in close contact with each other.

  The transparent ring 15a is made of a colorless and transparent acrylic resin or polycarbonate resin. The trim rings 15b and 15c are formed, for example, by applying chromium plating to an ABS resin so as to have a light shielding property.

As shown in FIG. 5, the trim rings 15 b and 15 c are provided with a chrome plating layer P on all surfaces except the surface facing the liquid crystal panel 2. Accordingly, the chromium plating layer P is also applied to the wall surfaces 15ba and 15ca, which are the wall surfaces facing the transparent ring 15a of the trim rings 15b and 15c. The chromium plating layer P applied to the wall surfaces 15ba and 15ca functions as a light reflection layer having a high reflectance.
The transparent ring 15a, the trim ring 15b, and the trim ring 15c are fixed with their entire interfaces closely contacting each other.

  On the screen 21 of the liquid crystal panel 2, as shown in FIG. 3, an illumination image A, which is a design image portion, is formed in a portion overlapping the transparent ring 15 a or a portion slightly wider than a portion overlapping the transparent ring 15 a. Yes. The illumination image A plays a role of a light source for causing the transparent ring 15a of the decorative ring 15 to emit and display light. The transparent ring 15a is transmitted and illuminated by the light emitted from the illumination image A and is emitted and displayed. The As a result, the decorative member 15 is visually recognized with the metallic glossy trim rings 15b and 15c arranged on both sides of the transparent ring 15a that emits and displays arcs.

  The light emitted from the illumination image A enters the transparent ring 15a, and a part of the light travels while being repeatedly reflected on the wall surface of the transparent ring 15a as shown in FIG. Exit. Here, the transparent ring 15a, the trim ring 15b, and the trim ring 15c are fixed in close contact with the entire interface. In other words, the transparent ring 15a and the trim ring 15b and the trim ring 15c arranged on both sides thereof are fixed with the entire opposing surfaces being in close contact with each other. For this reason, the wall surface facing the trim ring 15b of the transparent ring 15a and the wall surface facing the trim ring 15c act as mirror surfaces for the light traveling in the transparent ring 15a. Therefore, the light from the illumination image A that has entered the transparent ring 15a is reflected with high efficiency on each wall surface and guided to the front surface of the transparent ring 15a with almost no attenuation. As a result, even when the projection length of the transparent ring 15a from the liquid crystal panel 2 (H in FIG. 4) is increased to enhance the stereoscopic effect of the decorative ring 15, the illumination ring incident on the transparent ring 15a is used. Light from the image A can be guided and emitted to the front surface of the transparent ring 15a with high efficiency, and the emission luminance of the transparent ring 15a can be increased. Further, a chromium plating layer P as a light reflection layer is applied to the wall surfaces 15ba and 15ca which are the wall surfaces of the trim rings 15b and 15c facing the transparent ring 15a. For this reason, even if light leaks from the transparent ring 15a, the light is reflected by the chromium plating layer P on the wall surfaces 15ba and 15ca and travels again in the transparent ring 15a. Therefore, the light from the illumination image A that has entered the transparent ring 15a can be guided and emitted to the front surface of the transparent ring 15a with high efficiency, and the emission luminance of the transparent ring 15a can be increased.

  In the illumination image A which is a design image portion, as shown in FIG. 1, a pointer indicator 26 which is a high-intensity portion having a dot shape and higher brightness than the surroundings is provided as an image in a portion corresponding to an extension of the pointer 23. Is formed. The pointer indicator 26 always rotates around the virtual center C integrally with the pointer 23. When this is viewed from the driver side, the pointer indicator 26 is visually recognized as a bright luminescent spot on the extension of the tip of the pointer 23 on the transparent ring 15a. When the pointer 23 is rotated in response to the change in the traveling speed, the pointer indicator 26 is also rotated so as to be always on the extension of the pointer 23 in synchronization with the rotation. Thereby, the visibility of the speedometer S can be improved while making the appearance of the speedometer S novel. Here, the decorative ring 15, specifically, the trim ring 15 b on the inner peripheral side of the decorative ring 15 is installed away from the tip of the pointer 23 as shown in FIG. 1. Thereby, the pointer 23 and the pointer indicator 26 are completely separated and visually recognized as two displays.

  Further, in the illumination image A that is the design image portion, a route arrow indicator that is a linear and high-brightness portion having higher brightness than the surroundings is shown in a portion corresponding to the extension of the route arrow 25 as shown in FIG. 27 is formed as an image. When the direction of the direction arrow 25 changes, the direction arrow indicator 27 rotates around the virtual center C so that it is always on the extension of the direction arrow 25 in conjunction with it. When viewed from the driver side, the route arrow indicator 27 is visually recognized as a bright bright line on the extension of the tip of the route arrow 25 on the transparent ring 15a. Then, when the course arrow 25 rotates in response to the indicated change in the course direction, the course arrow indicator 27 also rotates so as to be always on the extension of the course arrow 25 in synchronization therewith. Thereby, the visibility of the navigation guide N can be improved while making the appearance of the navigation guide N novel. Here, the decorative ring 15, specifically, the trim ring 15 b on the inner peripheral side of the decorative ring 15 is installed away from the tip of the path arrow 25 as shown in FIG. 1. Thereby, the course arrow 25 and the course arrow indicator 27 are completely separated and visually recognized as two displays.

  As shown in FIG. 2, a printed circuit board 5 is disposed on the back side of the liquid crystal panel 2. The printed board 5 is made of, for example, a glass epoxy board or the like, and forms an electric circuit of the combination meter 1. The liquid crystal panel 2 and the light emitting diode 4 described above are electrically connected to the printed circuit board 5. For the connection between the liquid crystal panel 2 and the printed circuit board 5, for example, an FPC (Flexible Printed Circuit) (not shown) is used. A controller 10 that controls the display operation of the liquid crystal panel 2 is mounted on the printed circuit board 5. The controller 10 calculates the traveling speed of the vehicle based on an external electrical signal, that is, a detection signal from the vehicle speed sensor 13, drives the liquid crystal panel 2 to display it, and outputs a position signal from the navigation system device 14. Based on this, the liquid crystal panel 2 is driven so that the course arrow 25 is displayed on the navigation guide N. The controller 10 is composed of, for example, a microcomputer. The controller 10 also performs lighting / extinguishing control of the light emitting diode 4.

  A facing plate 7 is mounted on the front side of the liquid crystal panel 2. The facing plate 7 is formed, for example, in a substantially frame shape from a resin material or the like, and is disposed in close contact with the outer peripheral portion of the liquid crystal panel 2. A transparent cover 8 is attached to the viewer side (left side in FIG. 2) end of the facing plate 7. The transparent cover 8 is formed of a light-transmitting material, for example, a thin plate such as acrylic resin or polycarbonate resin, and prevents foreign matter (dust, water droplets, etc.) from entering the combination meter 1 to keep the surface of the liquid crystal panel 2 clean. Yes.

  A casing 6 is arranged behind the facing plate 7 (right side in FIG. 2). The casing 6 is formed of, for example, a resin material or the like, and accommodates and fixes the liquid crystal panel 2 and the printed board 5 described above.

  A lower cover 9 is disposed behind the casing 6 (on the right side in FIG. 2). The lower cover 9 covers the opening on the rear end side of the casing 6 to prevent entry of dust, moisture, etc. into the casing 6.

  Next, the electric circuit configuration of the combination meter 1 according to the first embodiment of the present invention will be described with reference to FIG.

In the combination meter 1 according to the first embodiment of the present invention, as shown in FIG.
The controller 10 is constantly supplied with power from the battery 12. Further, an ignition switch 11 is connected to the controller 10 so as to be able to detect its operating state (ON or OFF). A liquid crystal panel 2 and a light emitting diode 4 are connected to the controller 10. The controller 10 is connected to a vehicle speed sensor 13 for detecting the traveling speed of the vehicle so that a detection signal can be input. The vehicle speed sensor 13 detects the rotational speed of the output shaft of the transmission, for example, the rotational speed of the propeller shaft, for example. A navigation system device 14 is connected to the controller 10 so that a route instruction information signal can be input.

  Next, the operation of the combination meter 1 according to the first embodiment of the present invention will be described.

  When the ignition switch 11 is turned on by the driver, the controller 10 detects this and controls the combination meter 1 to be in an operating state. That is, the controller 10 activates the liquid crystal panel 2 and lights the light emitting diode 4. When the liquid crystal panel 2 is activated, the following three images are formed on the screen 21. First, a speedometer S composed of numbers 22 and hands 23 is formed, and the traveling speed of the automobile calculated by the controller 10 based on the detection signal from the vehicle speed sensor 13 is displayed. Second, a navigation guide Nga composed of a course arrow 25 and the like is formed, and the course of the automobile calculated by the controller 10 based on the course instruction information signal from the navigation system device 14 is displayed as the course arrow 25. Third, an illumination image A for illuminating the transparent ring 15a of the decoration ring 15 is formed, and the transparent ring 15a is lit and displayed by being transmitted and illuminated by the light emitted from the illumination image A. At this time, in the illumination image A, a pointer indicator 26 is formed on the extension of the pointer 23 of the speedometer S, and a route arrow indicator 27 is formed on the extension of the route arrow 25 of the navigation guide N. In the illumination image A, the light emission luminance of the pointer indicator 26 and the route arrow indicator 27 is set higher than the light emission luminance of the surrounding portions, for example, so that the driver looks conspicuously bright.
