[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a black face meter used in a vehicle, and to a display device suitable for displaying an indication by the meter at a distance from a driver's seat by using a lens. .

[0002]

2. Description of the Related Art The display surface of an instrument incorporated in an instrument panel is generally short in distance from a driver's eye point. Due to the large amount, it is conceivable that the instrument display is difficult to read and the danger of driving, especially during high-speed driving.

In order to make it easier to see the display of the instrument during operation, a lens is arranged at the opening of the instrument panel, and a self-luminous instrument body is provided behind the lens. When the display is viewed through a lens, the display of the instrument main body becomes a virtual image by the lens and is displayed at a position further back than the position of the instrument main body, thereby enabling a remote display of the instrument main body. This improves the visibility of the display by the user.

[0004]

However, in the case of a conventional instrument for a vehicle, for example, FIG.
As shown in FIG. 3, a main instrument main body 1 for displaying a speed display and an engine rotation display, and a sub-instrument main body 2 for displaying a liquid temperature and a remaining fuel amount are arranged in the same instrument frame 3 and a composite instrument 4. , The overall display surface A of the composite instrument 4
Are of a wide variety of shapes. 5 is each instrument main body 1, 2
1 shows an illumination sphere for illuminating a transmitted light.

In order to perform the above-described distant display of the entire composite instrument 4 having such a wide display surface by using a lens, it is larger than the display surface A of the composite instrument 4 as shown in FIG. One or more lenses (Fresnel lenses) 6 having an area must be used. However, a general lens having a large display area has a problem that the aberration is large, and a display image is particularly distorted at a peripheral portion of the lens, thereby deteriorating the display quality.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of such a conventional problem. In a composite instrument comprising a plurality of instrument bodies, the instrument body which is expected to be displayed at a distance is located at the center of the lens. The other instrument body that is located at the rear of the lens and that does not expect distant display is located close to the back of the lens at the periphery of the lens, and the instrument body located at the center is not effective distant display. , The instrument body placed on the lens periphery is displayed in the vicinity without distortion,
An object of the present invention is to provide a display device capable of improving display quality.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described in detail based on an embodiment shown in FIG.

Reference numeral 11 denotes a main instrument main body for displaying, for example, the speed of an automobile or the number of revolutions of an engine. The main instrument body 11 is provided with a pointer 13 and a character by a lighting means 12 provided in the instrument main body 11. The plate 14 is for light emission display. Reference numeral 15 denotes a sub-instrument main body for displaying, for example, liquid temperature and the like, and 16 denotes a sub-instrument main body for displaying the remaining amount of fuel.
2, the display surface 17 is illuminated and displayed.
Reference numeral 18 denotes the main instrument main body 11 and the sub instrument main body 15,
16 is a wide Fresnel lens disposed in front of the two Fresnel lenses 1 in this embodiment.
Although 8 is superimposed, this may be a single Fresnel lens. The main instrument main body 11 is disposed at the center behind the Fresnel lens 18 with a distance L therebetween.
Are arranged close to the peripheral portion and the back surface.

Therefore, each of the above-mentioned instrument main bodies 11, 15, 16
When the display is viewed through the Fresnel lens 18, the main instrument main body 11 arranged at the center has the Fresnel lens 18 because the display surface and the rear surface of the Fresnel lens are separated by the distance L. Is enlarged and displayed as a virtual image at a position twice as long as the distance L, and the display of the main instrument main body is a high magnification distant display. Further, since the display surfaces of the sub-instrument bodies 15 and 16 are close to the rear surface of the Fresnel lens 18, there is no lens effect, and therefore, no aberration is caused by the lens and the sub-instrument body 1
The display of high display quality can be obtained without changing the display of 5 and 16.

[0010]

As described above, according to the present invention, the instrument main body 11, which is expected to provide a distant display in a composite instrument composed of a plurality of instrument main bodies 11, 15, and 16, is separated at the center of the lens and behind the lens. Since the instrument main bodies 15 and 16 which are disposed and do not expect a distant display are arranged close to the peripheral portion and the rear surface of the lens, the display of each instrument main body is viewed through the lens, and therefore, it is a display device. According to this, the instrument main body 11 disposed at the center of the lens is displayed at a distance according to the lens magnification, and the instrument main bodies 15 and 16 disposed at the peripheral edge of the lens are not affected by the lens and have high quality. The effect that a good 1: 1 display is obtained is obtained.
