JP-A-2003-66444

In the conventional liquid crystal display device, the light guided through the optical path control layer is reflected by the plurality of prism-shaped unevenness and emitted from the optical path control layer. However, when a conventional liquid crystal display device is applied to a display device, depending on the shape of the display device, it is difficult to emit light with sufficient brightness from the design portion of the display device.

Accordingly, an object of the present disclosure is to provide a display device capable of emitting high-luminance light from a design portion of the display device.

A display device according to an aspect of the present disclosure includes a translucent main body having a concave portion on its surface, a light source that emits light toward the concave portion, and a light source formed on a back surface of the main body. a first reflecting portion that reflects the light guided into the main body from the recess, and the concave portion has an inclined surface that reflects the guided light and a design portion that indicates a pattern.

In the present disclosure, light with high brightness can be emitted from the design portion of the display device.

FIG. 2 is a perspective view illustrating the display device according to the embodiment. FIG. 3 is a cross-sectional view illustrating a cross section of the display device taken along line III-III of FIG. FIG. 4 is a block diagram illustrating the display device according to the embodiment. FIG. 5 is a partially enlarged perspective view illustrating a concave portion of the display device according to the embodiment. FIG. 6 is a cross-sectional view illustrating a cross section of the display device taken along line VI-VI of FIG. 7A and 7B are plan views exemplifying the recessed portion of the display device according to the embodiment when it is lit and when it is extinguished. FIG. 8 is a perspective view illustrating a display device according to Modification 1 of the embodiment. FIG. 9 is a partially enlarged perspective view illustrating a concave portion of the display device according to Modification 1 of the embodiment. 10A is a partially enlarged perspective view illustrating concave dots of a display device according to Modification 2 of the embodiment. FIG. 10B is a partially enlarged perspective view illustrating convex dots of the display device according to Modification 2 of the embodiment. FIG.

A display device according to an aspect of the present disclosure includes a translucent main body having a concave portion on its surface, a light source that emits light toward the concave portion, and a light source formed on a back surface of the main body. a first reflecting portion that reflects the light guided into the main body from the recess, and the concave portion has an inclined surface that reflects the guided light and a design portion that indicates a pattern.

Thus, for example, light emitted from a light source is guided through the main body and reflected by the inclined surfaces of the recess. The light reflected by the inclined surface travels toward the first reflecting section and is reflected by the first reflecting section. The light reflected by the first reflecting portion travels toward the design portion. In this way, since the light emitted from the light source gathers at the design portion, the light can be emitted from the design portion. As a result, light with sufficient brightness can be ensured even with a configuration in which light is emitted from the design portion formed in the recess.

Therefore, light with high brightness can be emitted from the design portion of the display device. As a result, the display quality of the design portion displayed with light can be improved.

In the display device according to one aspect of the present disclosure, the first reflecting section is a light reflecting coating agent or a light reflecting sheet.

In this way, the first reflecting section can reliably reflect the guided light.

In the display device according to one aspect of the present disclosure, concave or convex dots are applied to the inclined surface.

In this way, the dots can reflect light toward the first reflecting portion, so the light reflected by the first reflecting portion goes toward the design portion. As a result, light with higher brightness is emitted from the design portion.

In the display device according to one aspect of the present disclosure, a light source pair including a pair of the light sources that emit light toward the recess is arranged so as to sandwich the recess.

In this way, since light enters from both sides of the concave portion, light with reduced luminance unevenness is emitted from the design portion.

In the display device according to an aspect of the present disclosure, a plurality of light source pairs are arranged, and the display device further includes a second reflector that reflects light between two adjacent light source pairs.

In this way, of the two light source pairs, the second reflector is arranged between the light source pair on one side and the light source pair on the other side, so that the light emitted by the light source pair on one side is emitted. The first area of the part and the second area of the design part from which the light emitted by the light source pair on the other side is emitted can be separately illuminated.

For example, when only the light source pair on one side is turned on, it is possible to prevent light from being emitted from the first region and light from the second region. In addition, when only the light source pair on the other side is turned on, it is possible to prevent the light from being emitted from the second region and the light from the first region. Therefore, the user can easily recognize the pattern of the design portion shown in the selected concave portion.

In the display device according to one aspect of the present disclosure, the width of the second reflecting section in the height direction is larger than the width of the light source pair in the height direction.

Therefore, the first region of the design portion from which the light emitted by the light source pair on one side is emitted and the second region of the design portion from which the light emitted by the light source pair on the other side is emitted can be more reliably aligned. can be distinguished from each other.

In the display device according to an aspect of the present disclosure, the second reflecting section has a metal material or a light reflecting coating agent arranged in a groove formed in the main body.

Thus, since the second reflecting portion is arranged in the groove portion, the light emitted from the light source can be reflected.

A display device according to an aspect of the present disclosure includes a light shielding part that is laminated on the surface of the main body and blocks light other than the part where the design part is formed, and the design part guides light through the main body. light is emitted.

In this way, since the light shielding section suppresses the emission of light, it is possible to suppress the leakage of light from places other than the desired place, and to allow the light to be emitted from the desired place, that is, the design portion.

In the display device according to one aspect of the present disclosure, the light source is arranged in a posture in which the optical axis of the light emitted by the light source intersects the inclined surface.

In this way, since the light source emits light toward the inclined surface, the light reflected by the inclined surface is reflected by the first reflecting portion and easily directed toward the design portion. That is, the dots on the inclined surface can reduce the amount of light reflected toward the light source side, compared to the case where no dots are formed on the inclined surface. Therefore, by reducing the amount of stray light or absorbed light, it is possible to suppress a decrease in the amount of light emitted from the design portion.

In the display device according to one aspect of the present disclosure, the light source is arranged inside the main body.

For example, when the light source is arranged on the side surface of the main body or arranged on the back side of the main body, the size of the display device is increased. However, since the light source can be accommodated inside the main body in this way, it is possible to suppress an increase in size of the display device.

Hereinafter, embodiments will be specifically described with reference to the drawings. It should be noted that each of the embodiments described below is a specific example of the present disclosure. Numerical values, shapes, materials, constituent elements, arrangement positions and connection forms of constituent elements, and the like shown in the following embodiments are examples, and are not intended to limit the present disclosure.

[Constitution]
FIG. 1 is a perspective view illustrating a storage box 100 having a display device 1 according to an embodiment. FIG. 1 illustrates the interior of a vehicle.

As shown in FIG. 1, a storage box 100 is arranged in the compartment of the vehicle. The storage box 100 can store eyeglasses, wallets, and the like. Note that the storage box 100 is not limited to a vehicle, and may be an aircraft, a facility such as a house, or the like, and the place of arrangement is not particularly limited.

A storage box 100 includes a display device 1 .

The display device 1 has, for example, functions such as opening and closing the storage box 100 and the ceiling window (for example, a sunroof) and turning on the lighting device in the passenger compartment. The display device 1 serves as a lid for the storage box 100 . The display device 1 has a plurality of operation units 3 for executing such functions. The operating portion 3 is a portion corresponding to a concave portion 120 of the main body 10, which will be described later. The user can bring out the functions of the display device 1 by touching the operation unit 3 .

The display device 1 will be described with reference to FIGS. 2 to 4. FIG. FIG. 2 is a perspective view illustrating the display device 1 according to the embodiment. FIG. 3 is a cross-sectional view illustrating a cross section of the display device 1 taken along line III-III in FIG. FIG. 4 is a block diagram illustrating the display device 1 according to the embodiment.

As shown in FIG. 2, the display device 1 is a flat panel. The display device 1 displays a pattern (a design portion 110 in FIG. 3 to be described later) for opening and closing the storage box 100 described above. The pattern is omitted in FIG. There are no particular restrictions on the pattern, and any pattern may be used.

As shown in FIGS. 2 to 4, the display device 1 includes a main body 10, a plurality of light sources 20, a first reflector 31, a second reflector 32 in FIG. and Note that the control circuit 40 may be built in the main body 10 or may be provided outside the main body 10 .

As shown in FIGS. 3 and 4, the main body 10 has translucency. The main body 10 is a light guide through which the light emitted by the light source 20 is guided. In the main body 10 , light emitted from the light source 20 mounted on the control circuit 40 is guided, and the guided light is emitted from the design portion 110 . The main body 10 is made of a transparent material, for example, a resin member such as acrylic or polycarbonate.

The body 10 also has a plurality of recesses 120 on the surface 10a. The concave portion 120 is a guide for guiding the user's finger when the user operates the display device 1 . A third reflecting portion 113 is layered on the surface 10 a of the concave portion 120 of the main body 10 . The recess 120 has a bottom surface 121 and an inclined surface 122 .

The design portion 110 showing the pattern is laminated on the bottom surface 121 . The design section 110 is a pattern that displays the functions of the display device 1 to the user who performs the operation. When the surface of the display device 1 is viewed, the pattern of the design portion 110 cannot be recognized or is difficult to recognize when the light source 20 is turned off. It is an aspect that can recognize. The pattern may be any pattern, but in this embodiment, the function of the display device 1 is shown.

The design portion 110 is a portion from which light is emitted from the display device 1 . The design portion 110 has a decorative portion 111a and a thin portion 111b. The decorative portion 111 a is a translucent film or sheet-like layer laminated on the bottom surface 121 of the recess 120 . The thin portion 111b is part of the third reflecting portion 113 laminated on the upper surface (the surface on the positive side of the X-axis) of the decorative portion 111a. In the thin portion 111b, the third reflecting portion 113 is laminated thinner than other portions. Specifically, the decorative portion 111a corresponding to the pattern of the design portion 110 is laminated on the surface 10a of the main body 10, and the third reflecting portion 113 is further laminated thereon. Therefore, the surface of the operation portion 3 (the portion corresponding to the concave portion 120 of the main body 10) of the display device 1 is flush, but the upper surface portion (thin portion 111b) of the decorative portion 111a is thin. As a result, light is transmitted through the thin portion 111b.

As another example, the design portion 110 may be part of the main body 10 (protruding portion). That is, a part of the main body 10 may be formed instead of the decorative portion 111a. As yet another example, the design portion 110 is a portion where the third reflecting portion 113 is not laminated, that is, a portion where the surface 10a of the main body 10 is exposed, and is a space through which the light guided through the main body 10 passes. may In this way, it is sufficient to emit light for highlighting the pattern indicated by the design section 110 .

As shown in FIG. 3 , the third reflecting portion 113 reflects the light guided through the main body 10 toward the first reflecting portion 31 . In this embodiment, the third reflecting portion 113 is laminated on the surface 10a of the main body 10. As shown in FIG. The third reflecting portion 113 is a light-reflecting coating agent, a light-reflecting sheet, or the like having a light-reflecting function. The third reflecting portion 113 is an example of a light shielding portion. A light absorbing material may be used instead of the third reflecting portion 113 .

The inclined surface 122 is a portion of the main body 10 that surrounds the bottom surface 121 when the concave portion 120 is viewed from the surface 10a. When the concave portion 120 is viewed in cross section, the inclined surface 122 is inclined so as to narrow from the X-axis positive direction of the concave portion 120 toward the X-axis negative direction. The inclined surface 122 receives the light emitted by the light source 20 and reflects the incident light. It is preferable that the inclined surface 122 totally reflects the light. The light reflected by the inclined surface 122 travels toward the first reflecting section 31 .

The multiple light sources 20 emit light toward the recess 120 . Specifically, the plurality of light sources 20 are mounted on the control circuit 40 in a state of being fixed by the reflectors 22, for example, in an attitude of emitting light in the Y-axis direction in FIG. More specifically, the light source 20 is arranged on the main body 10 in a posture in which the direction of the optical axis of emitted light, that is, the Y-axis direction, and the inclined surface 122 intersect.

Moreover, the plurality of light sources 20 emit light toward the recess 120 so as to sandwich the recess 120 . That is, the pair of light sources 20 among the plurality of light sources 20 are arranged on one side of the recess 120 (for example, the Y-axis plus direction side) and on the other side of the recess 120 (for example, the Y-axis minus direction side). and a light source 20 arranged. In other words, the pair of light sources 20 (hereinafter sometimes referred to as a light source pair 20t) is such that the light source 20 arranged on one side and the light source 20 arranged on the other side of the recess 120 face each other with the recess 120 interposed therebetween. . FIG. 3 of the present embodiment illustrates a case where a pair of light sources 20 are arranged in the Y-axis direction.

Each of the plurality of light sources 20 is configured by, for example, an LED (Light Emitting Diode). Each of the plurality of light sources 20 can emit light such as white light, blue light, red light, and green light. Note that each of the plurality of light sources 20 may be configured by a light-emitting element other than an LED, and may be configured by, for example, an organic EL (Electro Luminance) light bulb.

In addition, each of the plurality of light sources 20 may be configured by the same kind of light source, for example, the same kind of light-emitting element (for example, LED). In this case, the same kind of light-emitting elements are light-emitting elements that emit light with the same luminance under the same light-emitting conditions (for example, the magnitude of applied current or power).

The first reflecting portion 31 is laminated on the back surface 10b of the main body 10, and reflects the light guided through the main body 10 toward the second reflecting portion 32, the design portion 110, and the like. The first reflector 31 functions as a circuit board on which a plurality of light sources 20 and the like are mounted and which has a conductive pattern (not shown). The first reflecting portion 31 is a light-reflecting coating material, a light-reflecting sheet, or the like. Although the first reflecting portion 10b is laminated on the rear surface 10b of the main body 10, the rear surface 10b of the main body 10 may be the first reflecting portion having a light reflecting function.

The second reflector 32 will be described with reference to FIGS. 5 and 6. FIG.

FIG. 5 is a partially enlarged perspective view illustrating the concave portion 120 of the display device 1 according to the embodiment. FIG. 6 is a cross-sectional view illustrating a cross section of the display device 1 taken along line VI-VI of FIG.

The second reflecting portion 32 is a metal material or a light reflecting coating material disposed in the groove portion 10c formed in the main body 10. As shown in FIG. Specifically, the light reflecting coating material as the second reflecting portion 32 may be formed by forming a light reflecting coating such as white or silver on the surface of a film such as polycarbonate or polyethylene terephthalate. Alternatively, the second reflecting portion 32 may be configured by filling the groove portion 10c with a light reflecting paint as a light reflecting coating material. A control circuit 40 is layered on the second reflecting section 32 . As shown in FIG. 6, the main body 10 exists between the second reflecting section 32 and the third reflecting section 113, but the main body 10 may be omitted. In addition, the width of the second reflecting portion 32 in the height direction (the thickness in the X-axis direction) is larger than the width in the height direction of the light source 20 (the width in the X-axis direction). The thickness (thickness in the Z-axis direction) of the second reflecting portion 32 is several millimeters or less.

As shown in FIG. 4, control circuit 40 controls the operation of light source 20 . The control circuit 40 exhibits a function according to the position of the design portion 110 corresponding to the position detected by the touch sensor 50 . For example, when the touch sensor 50 detects the position corresponding to the design portion 110 and the operation portion 3 is touched, the control circuit 40 detects the pattern indicated by the design portion 110 corresponding to the touched operation portion 3 . Accepts input of commands according to

Further, the control circuit 40 operates the display device 1, the ceiling window, the lighting device, etc. in a plurality of operation modes. For example, the control circuit 40 has an operation mode for opening/closing the storage box 100, an operation mode for opening/closing the ceiling window, an operation mode for turning on/off the lighting device in the passenger compartment, and the like. That is, the control circuit 40 operates the display device 1, the ceiling window, the lighting device, etc. according to the pattern indicated by the design section 110. FIG. Note that the control circuit 40 may be formed integrally with the first reflecting section 31 .

The touch sensor 50 is arranged, for example, on the front surface 10a side or the rear surface 10b side of the main body 10, and detects a touch position, which is a position touched by the user. The touch sensor 50 is, for example, a capacitive sensor, an electromagnetic induction sensor, or the like.

[motion]
As shown in FIG. 3 , in such a display device 1 , for example, light emitted by the light source 20 is guided through the main body 10 and enters the inclined surface 122 of the concave portion 120 . The light incident on the inclined surface 122 is reflected by the inclined surface 122 and travels toward the first reflecting section 31 . The light incident on the first reflecting portion 31 is reflected by the first reflecting portion 31 and travels toward the design portion 110 . Part of the light that has entered the design portion 110 is emitted from the design portion 110 , and the other portion of the light is reflected by the third reflection portion 113 and enters the first reflection portion 31 . In this way, the light is emitted from the design portion 110 while being repeatedly reflected inside the main body 10 .

FIGS. 7A and 7B exemplify states when the lamp is lit and when the lamp is extinguished. FIG. 7 is a plan view exemplifying the recessed portion 120 of the display device 1 according to the embodiment when it is lit and when it is extinguished.

As shown in FIG. 7, when the light source 20 is turned on, in the design portion 110, light passes through the decorative portion 111a and the thin portion 111b in this order and is emitted. Thereby, the user can recognize the pattern of the design portion 110 that appears when the light is turned on. Further, when the display device 1 is turned off, the surface of the operation portion 3 of the display device 1 is flush with the surface, so that the user cannot or hardly recognizes the pattern of the design portion 110 .

[Effect]
Next, functions and effects of the display device 1 according to the present embodiment will be described.

The display device 1 according to the present embodiment has a translucent main body 10 having a concave portion 120 on the surface 10a, a light source 20 that emits light toward the concave portion 120, and a back surface 10b of the main body 10. A first reflecting portion 31 that reflects the light that is laminated and guided from the light source 20 to the inside of the main body 10 is provided. The concave portion 120 has an inclined surface 122 that reflects guided light and a design portion 110 that shows a pattern. Further, the light source 20 is arranged in a posture in which the optical axis J of the light emitted by the light source 20 and the inclined surface 122 intersect.

For this reason, the light reflected by the inclined surface 122 is reflected by the first reflecting portion 31 and easily travels toward the design portion 110 . Light emitted by the light source 20 can be collected in the design portion 110 . Accordingly, even with a configuration in which light is emitted from the design portion 110 formed in the concave portion 120, light with sufficient brightness can be ensured.

Therefore, light with high brightness can be emitted from the design portion 110 of the display device 1 . As a result, the display quality of the design portion 110 displayed with light can be improved.

Further, in the display device 1 according to the present embodiment, a light source pair 20t including a pair of light sources 20 that emit light toward the recess 120 is arranged so as to sandwich the recess 120 therebetween. Therefore, since light enters from both sides of the concave portion 120 , light with luminance unevenness suppressed is emitted from the design portion 110 .

Moreover, the display device 1 according to the present embodiment further includes a second reflecting portion 32 that reflects light between the two adjacent light source pairs 20t. As a result, since the second reflecting portion 32 is arranged between the light source pair 20t on one side and the light source pair 20t on the other side of the two light source pairs 20t, the light emitted by the light source pair 20t on one side is The first region R1 of the design portion 110 from which light is emitted and the second region R2 of the design portion 110 from which the light emitted by the light source pair 20t on the other side is emitted can be separately illuminated.

For example, when only the light source pair 20t on one side is turned on, it is possible to prevent light from being emitted from the first region R1 and from the second region R2. Further, when only the light source pair 20t on the other side is turned on, it is possible to prevent light from being emitted from the second region R2 and from the first region R1. Therefore, it becomes easier to recognize the pattern of the design portion 110 of the display device 1 in the concave portion 120 selected by the user.

Further, the display device 1 according to the present embodiment includes a third reflecting portion 113 which is laminated on the surface 10a of the main body 10 and blocks light other than the portion where the design portion 110 is formed. Light guided through the main body is emitted from the design portion. Accordingly, since the light shielding section suppresses light emission, it is possible to suppress light leakage from places other than the desired place, and to allow light to be emitted from the desired place, ie, the design portion 110 .

Further, in the display device 1 according to the present embodiment, since the light source 20 is arranged inside the main body 10, for example, when the light source 20 is arranged on the side surface of the main body 10 or arranged on the rear surface 10b side of the main body 10, Compared to , the display device 1 can be suppressed from becoming large.

(Modification 1 of Embodiment)
A configuration of a display device 200 according to Modification 1 of the embodiment will be described with reference to FIGS. 8 and 9. FIG.

FIG. 8 is a perspective view illustrating a display device 200 according to Modification 1 of the embodiment. FIG. 9 is a partially enlarged perspective view illustrating the concave portion 120 of the operation unit 203 in the display device 200 according to Modification 1 of the embodiment.

Other configurations in this modified example are the same as those in the embodiment unless otherwise specified, and the same configurations are denoted by the same reference numerals, and detailed description of the configuration is omitted.

The operation unit 203 of the display device 200 illustrated in FIG. 8 is elongated in the Z-axis direction. As shown in FIG. 9 , in this modified example, the second reflecting portion 32 is also arranged on the X-axis negative direction side of the concave portion 120 of the operating portion 203 . Specifically, a plurality of light source pairs 20 t are arranged in one recess 120 . A second reflector 32 is arranged between the light source pair 20t on one side and the light source pair 20t on the other side of the two adjacent light source pairs 20t. As shown in FIG. 9, if one light source 20 of one light source pair 20t is the first light source 20a and the other light source 20 is the second light source 20b, the second reflecting portion 32 straddles the concave portion 120. , it extends from the first light source 20a side to the second light source 20b side. The length in the longitudinal direction (Y-axis direction) of the second reflecting portion 32 is longer than the length from the first light source 20a to the second light source 20b.

In this modified example, the light emitted from the design portion 110 of the concave portion 120 will be described.

For example, the region of the design portion 110 of the recess 120 corresponding to the light source pair 20t on one side is defined as a first region R11, and the region of the design portion 110 of the recess 120 corresponding to the light source pair 20t on the other side is defined as a second region R12. and The first region R11 and the second region R12 are adjacent to each other. In this case, light emitted from the light source pair 20t on one side is emitted from the first region R11. Since the light emitted from the light source pair 20t on one side is reflected by the second reflecting portion 32, it is difficult for the light to be emitted from the second region R12. The light emitted from the light source pair 20t on the other side is emitted from the second region R12. Since the light emitted from the light source pair 20t on the other side is reflected by the second reflecting portion 32, it is difficult for the light to be emitted from the first region R11.

In this way, since the second reflecting portion 32 is arranged between the light source pair 20t on one side and the light source pair 20t on the other side, and the second region R12 of the design portion 110 from which the light emitted by the light source pair 20t on the other side is emitted.

(Modification 2 of Embodiment)
A configuration of a display device according to Modification 2 of the embodiment will be described with reference to FIGS. 10A and 10B.

FIG. 10A is a partially enlarged perspective view illustrating concave dots 122a of the display device according to Modification 2 of the embodiment. FIG. 10B is a partially enlarged perspective view illustrating convex dots 122b of the display device according to Modification 2 of the embodiment.

Other configurations in this modified example are the same as those in the embodiment unless otherwise specified, and the same configurations are denoted by the same reference numerals, and detailed description of the configuration is omitted.

In this modification, as shown in FIG. 10A, a plurality of concave dots 122a are formed on the inclined surface 122 of the concave portion 120. As shown in FIG. Further, as shown in FIG. 10B, a plurality of convex dots 122b are formed on the inclined surface 122 of the concave portion 120. As shown in FIG. The concave dots 122a or the convex dots 122b may be conical, truncated conical, pyramidal, truncated pyramidal, and the like. Such dots 122a may be formed, for example, by shaving with a tool such as a diamond turning tool after preparing the main body 10, or by laser irradiation.

In the display device according to this modified example, since the concave or convex dots 122 a are provided on the inclined surface 122 , the light incident on the inclined surface 122 is easily reflected toward the first reflecting section 31 . . That is, the dots 122a on the inclined surface 122 can reduce the amount of light reflected toward the light source 20 compared to the case where the dots 122a are not formed on the inclined surface 122. FIG. Therefore, by reducing the amount of stray light or absorbed light, it is possible to suppress a decrease in the amount of light emitted from the design portion 110 .

(others)
As described above, the present disclosure has been described based on the embodiment and modified examples 1 and 2 of the embodiment, but the present disclosure is not limited to the display device described above.

For example, in the display devices according to each of the above-described embodiments and modifications 1 and 2 of the embodiments, a member in which the light source, the control circuit, the second reflector, etc. are arranged on the surface of the first reflector is formed of prepared gold.
