Description

  The present invention relates to a display device that illuminates a display and a surrounding frame portion.

  2. Description of the Related Art Conventionally, for example, a display device for a vehicle, particularly an automobile, has been provided with a display for performing various displays, which is illuminated by light emitted from a light emitter disposed on the back side. ing. In this case, on the back side of the display, a reflector for reflecting the light emitted from the light emitter toward the display is provided together with the light emitter, thereby illuminating the display evenly. It has become.

  By the way, in recent years, it has been considered to illuminate not only the above-mentioned display but also the surrounding frame portion in, for example, a ring shape. The reflector which reflects the light which emitted from toward the frame part is provided.

  However, as described above, in order to illuminate the display and the surrounding frame portion, if the display reflector and the frame reflector are individually provided, from individual manufacture to assembly of those components. It can be time consuming and costly.

  The present invention has been made in view of the above circumstances, and therefore the object thereof is to separately provide a reflector for the display and a reflector for the frame to illuminate the display and the surrounding frame. Therefore, it is desirable to provide a display device capable of reducing the cost.

  In order to achieve the above object, a display device according to the present invention illuminates a display and a surrounding frame portion with light emitted from light emitters arranged on the back side thereof, and emits light from the display light emitter. A reflector unit formed by integrally forming a reflector for display that reflects light toward the display and a reflector for frame that reflects light emitted from the light emitter for the frame toward the frame; Features.

  According to the above means, since the reflector for display and the reflector for frame portion are integrally formed in the reflector unit, it is possible to save time and labor from manufacturing to assembling these components.

Hereinafter, an example (one embodiment) of the present invention will be described with reference to the drawings.
First, FIG. 2 shows one of display devices for vehicles, particularly for automobiles. In this case, a wind direction / air volume display device for displaying a wind blowing direction and an air volume, 1, wind direction and air volume display 2 on the person's head, wind direction and air volume display 3 on the person's feet, car front wind display 4 and wind direction and air volume display 5 on the front wind In this case, the liquid crystal display 6 is used. The air volume is indicated by the number of arrows indicating the wind direction.

  As shown in FIG. 1, the liquid crystal display 6 has a front surface covered with a clear cover 7. The clear cover 7 is surrounded by an inner frame 8 and an outer frame 9, and is further surrounded by a transparent frame portion constituting member. The clear ring 10 is disposed so that almost all of the inner peripheral portion 10a of the clear ring 10, the front portion of the outer frame 9, and the clear cover 7 are exposed forward from the circular opening 12 of the panel 11. .

  A reflector unit 13 is disposed on the back side of the liquid crystal display 6. The reflector unit 13 is formed by integrally forming a display reflector 14 and a frame reflector 15 as shown in FIGS. 3 and 4. Specifically, the display reflector 14 has a bowl-like shape at the center ( A parabolic reflector), and a frame-shaped (ring-shaped) reflector 15 for the frame portion is located around it, and these are connected by four radial ribs 16. A rectangular frame 17 is present.

  The frame reflector 15 is formed in a slope shape that gradually decreases its height from one pair of diagonal corresponding positions 18, 18 of the frame 17 toward the other pair of diagonal corresponding positions 19, 19. Yes. Then, light emitter assembly holes 20, 21, and 21 are formed at diagonal positions of the frame 17 corresponding to the center portion of the display reflector 14 and the lowest portions (19, 19) of the frame reflector 15, respectively. is doing.

  Therefore, a circuit board 22 is disposed on the back side of the reflector unit 13, and the circuit board 22 has a necessary circuit pattern (not shown) and lamps 23, 24, and 24 are mounted thereon. is doing. These lamps 23, 24, and 24 are light emitters as backlights, and the lamps 23 are inserted into the light emitter assembly holes 20 in the display reflector 14 of the reflector unit 13 so that the lamps 24 and 24 are framed. The light emitter assembly holes 21 and 21 in the part reflector 15 are respectively inserted.

  Note that the liquid crystal display 6 has a translucent portion 25 that always transmits light (even if no voltage is applied by the transparent electrode plates 22, 23) around the periphery, and this translucent portion 25 is connected to the clear cover 7. This is brought into contact with the lower surface of the flange 7a so as to face the inner peripheral portion 10a of the clear ring 10.

  With the above configuration, the light emitted from the lamp 23 is reflected directly and by the display reflector 14, and is then applied to a portion of the central portion of the liquid crystal display 6 (the portion where the displays 1 to 5 are present). It works as a light. The light emitted from the lamps 24 and 24 is reflected directly and by the frame reflector 15, passes through the flange 7 a of the clear cover 7 from the light transmitting portion 25 around the liquid crystal display 6, and further clears. Through the inner peripheral portion 10a of the ring 10, the inner peripheral portion 10a of the clear ring 10, which is a peripheral frame portion of the portion where the above displays 1 to 5 of the liquid crystal display 6 covered with the clear cover 7 are present, is illuminated. .

  As described above, in the present configuration, the liquid crystal display 6 and the surrounding frame portion (the inner peripheral portion 10a of the clearing 10) are illuminated by the light emitted from the light emitters disposed on the back side thereof. The display reflector 14 that reflects the light emitted from the lamp 23 that is a light emitter for the liquid crystal toward the liquid crystal display 6, and the frame that reflects the light emitted from the lamps 24 and 24 that are light emitters for the frame toward the frame. The reflector for part 15 is integrally formed by the reflector unit 13. Thereby, compared with the thing of the conventional concept which has the reflector 14 for displays and the reflector 15 for a frame part separately, the effort from manufacture of those components to an assembly can be saved, and cost can be reduced.

Note that the present invention is not limited to a display device for a vehicle such as an automobile, and can be similarly applied to other display devices. Further, the display exemplified by the liquid crystal display 6 is not limited thereto.
In addition, the present invention is not limited to the embodiments described above and shown in the drawings, and can be implemented with appropriate modifications within a range not departing from the gist.
