Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device, and more particularly to a display device having a case in which a window member through which a display device is seen is insert-molded.

[0002]

2. Description of the Related Art Conventionally, a display device shown in FIG. 6 has been proposed. Reference numeral 1 is a case, and the case 1 is composed of a front case 1a and a rear case 1b. A liquid crystal display element 2, a light emitting diode display element 3 and a circuit board 4 are housed in the case 1. The circuit board 4 is electrically connected to the liquid crystal display element 2 and the light emitting diode display element 3 and supplies necessary power. Openings 5 and 6 are provided in front of the liquid crystal display element 2 and the light emitting diode display element 3 of the front case 1a, respectively.
Is visible. Translucent sheets 7 and 8 made of polycarbonate are attached to the openings 5 and 6, respectively, to prevent dust from entering through the openings 5 and 6.

[0003]

However, the translucent sheets 7 and 8 are merely attached to the front case 1a and have a fear of peeling off, and dust enters through the openings 5 and 6 to display each display. There is a problem that the display becomes difficult to be visually recognized because it adheres to the surfaces of the elements 2 and 3. Further, when the display device is applied to, for example, a water vehicle, the waterproof property is low, and there is a fear that water may enter and adversely affect the circuit elements mounted on the circuit board 4. The present invention provides a display device having excellent dustproofness and waterproofness.

[0004]

In order to solve the above-mentioned problems, the present invention provides a display device in which a display element is housed in a case, wherein the case is made of a translucent material provided so that the display element can be seen through. The window member is formed by insert molding.

Further, according to the present invention, in a display device in which a first display element and a second display element are housed in a case, the case is provided with a first window through which the first display element can be seen. The window member is integrally insert-molded with a transparent resin and a second window portion provided so that the second display element can be seen through.

Also, in the present invention, the window member has a connecting portion for connecting the first window portion and the second window portion, and the connecting portion is embedded by the insert molding. .

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Since a window member made of a translucent material which is provided so that a display element can be seen through is insert-molded, the window member does not peel off from the case, and the dustproof property and the waterproof property are improved. be able to.

Further, the first window portion which is provided so that the first display element can be seen through and the second window portion which is provided so that the second display element can be seen through are integrally formed of a translucent resin. By doing so, the number of parts of the window member set in the mold during insert molding can be reduced, and there is no fear of making the case complicated.

Further, by embedding the connecting portion connecting the first window portion and the second window portion by insert molding,
The connecting part is not visible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment in which the present invention is applied to a speed display device for a water vehicle will be described below with reference to the accompanying drawings.

Reference numeral 9 denotes a case, which is composed of a front case 9a and a rear case 9b. A window member 10 made of a translucent resin material (for example, PMMA) is insert-molded on the front case 9a. The window member 10 is the first
It has a window part 11 and a second window part 12. First window 11
Is rectangular, the second window 12 is circular, and the first window is
11 and the second window portion 12 are connected by a connecting portion 13.

A liquid crystal display element 14 (first display element), a light emitting diode display element 15 (second display element) and a circuit board 16 are housed in the case 9. Liquid crystal display element 14
The light emitting diode display element 15 can be seen through the first window portion 11 and the second window portion 12, respectively. Reference numeral 17 is a conductive rubber, and the conductive rubber 17 electrically connects the liquid crystal display element 14 and the circuit board 16. Further, the light emitting diode display element 15 is connected to the circuit board 16 by the lead terminal 18.

As shown in FIG. 2, the liquid crystal display element 14 illuminates the sun-shaped segment 19 to indicate the speed of the water vehicle. When the speed of the water vehicle exceeds a predetermined value, the light emitting diode display element 15 lights up in red to warn the driver of the speed excess.

Next, the front case 9a will be described in detail with reference to FIGS. As shown in FIG. 3, the window member 10
The first window portion 11 and the second window portion 12 are connected by a connecting portion 13 and are integrally formed. As shown in FIG. 4, the window member 10
Is set in a mold 20, and a heat-melted non-translucent resin (for example, ABS) is injected under pressure into the mold 20 to form a window member.
10 is insert-molded in the front case 9a. Connecting part 13
Is embedded by insert molding and is no longer visible (see FIG. 5).

Since the window member 10 is insert-molded in the front case 9a, the translucent sheet 7 described in the conventional example,
As in No. 8, there is no fear of peeling and the dustproof property and waterproof property can be improved. Further, since the first window portion 11 and the second window portion 12 of the window member 10 are connected by the connecting portion 13 and integrally formed, the number of parts of the window member 10 is reduced and the window member 10 is inserted at the time of insert molding. There is no fear that the work of setting 10 in the mold 20 becomes complicated.

The window member 10 of this embodiment is formed by integrally molding the first window portion 11 and the second window portion 12 with a light-transmitting resin material, for example, the first window portion. 11 and the second window 12 may be separate members made of glass.

The connecting portion 13 may be provided so as to be visible from the front side, but it is preferable to embed the connecting portion 13 to make it invisible as in this embodiment.

[0018]

According to the present invention, in a display device in which a display element is housed in a case, the case is formed by insert-molding a window member made of a light-transmissive material that is provided so that the display element can be seen through. It is possible to improve the dustproof property and the waterproof property.
