Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a display device excellent in display quality that can be applied to, for example, a vehicle instrument.

[0002]

[Prior art]

 In order to enhance the impression given to the user, a display device is known in which a light control member that is opaque on the surface of the display board at all times and is transparent only when used is placed so that the display board can be viewed only when it is used. (See, for example, Japanese Laid-Open Patent Publication No. 63-61118 and Japanese Utility Model Laid-Open No. 5-59242).

[0003]

[Problems to be solved by the device]

 In such a configuration, the display plate can be seen through the light control member when in use, and when not in use, the surface of the display device becomes dark black due to the light control member, which causes a large difference in the appearance and makes it difficult for the user. Although it gives a strong impression, when it was used, it had the same monotonous display as a typical display device covered with a transparent glass plate, and tended to lack interest.

Further, in a display device that displays an indicated amount or an indicated value in an analog (bar or segment) manner, it is difficult to instantly recognize the positional relationship of the indicated amount or the indicated value with respect to the whole. there were.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention provides a semi-transparent smoke member that reduces the transmission of light, a half mirror that is a display plate that is inclined behind the smoke member at a predetermined angle, and a rear half mirror The first light-emitting part that produces a display image by illuminating the indicated amount and the indicated value in the real image by the light passing through the half mirror and making the others dimly lit and the half mirror that is placed in front of the half mirror And a second light emitting member that forms a background with a virtual image by reflected light.

[0006]

[Action]

 When not in use, the surface of the display becomes dark black due to the smoke member, and when in use, a real display image appears floating on the background of a virtual image that is formed in the distance. It is bright and the others are half-lit and dim.

[0007]

【Example】

 Hereinafter, the present invention will be described with reference to the embodiments illustrated in the accompanying drawings.

Reference numeral 1 denotes a display device of the present invention, which is applied to a fuel gauge for a vehicle and shows a case of displaying a remaining fuel amount (indicated amount) by a bar display. Reference numeral 2 is a smoke member located in front of the display device 1, 3 is a half mirror serving as a display plate arranged behind the smoke member 2 at a predetermined angle (45 degrees forward), and 4 is a rear surface of the half mirror 3. The first light emitting member 5 which makes the display image A by illuminating the other image dimly in the real image by the light L1 passing through the half mirror 3 and making the others dimly illuminate is arranged in front of and below the half mirror 3 and the half mirror 3 It is a second light emitting member that forms a background B in a virtual image by the light L2 reflected by. Reference numeral 6 is a substrate that holds the light emitting members 4 and 5.

The first light emitting member 4 is designed to have a light transmitting portion corresponding to the display image A and is arranged on the rear surface of the half mirror 3, and is selectively driven according to the remaining amount of fuel during use. The display panel 41 has a plurality of light emitting diodes (LEDs) 42 for irradiating the light L1 from behind, and the display color of the light L1 is determined by the color of the design panel 41 and the emission color of the LED 42. The LED 41 is selectively driven according to the instruction amount to light a predetermined number to display the instruction amount, but those which should not be turned off are also driven by half lighting and are displayed dimly. . In addition, 43 is a case which divides the light emitting member 4.

The second light emitting member 5 includes a design panel 51 which is arranged to face a front surface of the half mirror 3 with a light transmitting portion corresponding to the background B, and a rear panel of the design panel 51 which is always driven during use. At least one lamp 52 for irradiating the light L2 is provided, and the display color of the light L2 is determined by the color of the design panel 51 and the emission color of the lamp 52. Reference numeral 53 is a case for partitioning the light emitting member 5.

In such a configuration, when not in use, the LED 41 and the lamp 51 are off, so that the display device 1 is dark and nothing is displayed on the smoke member 2.

During use, the lamp 52 is turned on, and the light L 2 that has passed through the design panel 51 is reflected by the front surface of the half mirror 3, so that the background B appears as a virtual image formed forward through the half mirror 3. Then, the display image A appears to overlap the background B by the light L1 that has passed through the design panel 41 and the half mirror 3 from the LED 42 that is lit or semi-lit depending on the remaining fuel amount. At this time, if the distance from the lamp 52 to the half mirror 3 is set to be longer than the distance from the LED 42 to the half mirror 3, the display image A looks as if it floats on the background B. . Therefore, the impression on the user is strong, and the instruction amount can be visually recognized instantly.

Further, since the display image A is configured such that the indicated amount is bright when illuminated and the other is semi-illuminated when dim, it is possible to instantly recognize the positional relationship of the indicated amount with respect to the whole.

It should be noted that the present invention is not limited to the above-described embodiment, and various modifications can be made within the scope of the gist. For example, when used as a cooling water thermometer, it is common to display the temperature (indicated value) in points. In this case, only one LED 42 corresponding to the indicated value should be turned on and the other half turned on. You can use segment display. Also, the display color of the background B can be switched by switching and lighting using a plurality of lamps 52 of different colors.

[Effect of device]

 The present invention relates to a semi-transparent smoke member that reduces the transmission of light, a half mirror that is a display plate that is placed behind the smoke member at a predetermined angle, and a light that passes through the half mirror behind the half mirror. Therefore, the indicated amount and indicated value are bright in the real image, and the others are dimly lit to produce the display image. The first light emitting member is arranged in front of the half mirror and the light reflected by the half mirror creates a virtual image. By using the second light emitting member that forms the background, the surface of the display device becomes dark black due to the smoke member when not in use, and the real display image floats on the background of the virtual image formed at a distance when in use. In addition, the displayed image is bright when the indicated amount and the indicated value are lit, and the other is dim when it is half lit, so the impression given to the user can be strengthened, and the finger for the whole is displayed. It is possible to instantly recognize the positional relationship between the quantity and the indicated value, and for example, it is possible to provide a display device having excellent display quality that can be adapted to something that must be instantly read, such as a vehicle instrument. .
