Abstract

PURPOSE:To improve the recognition performance by covering a fluorescent display body by a smoke lens, interlocked with a lighting switch, when the environment is dark such as at night, etc., in the captioned device which allows an image to be formed on a front glass through the illumination display by the fluorescent display body. CONSTITUTION:A fluorescent display tube unit 4 built in an instrument panel 3 irradiates the light supplied from a fluorescent display body 5 onto a front window glass 1 through a lens 7 in an opened port 6 formed onto the upper surface of the panel 3, and allows an image to be formed on the glass 1. In this case, a bracket 9 is pivotally supported 10 onto the fluorescent display tube unit 4, and a smoke lens 8 is installed onto the bracket 9. The bracket 9 is turned to the position covering above the fluorescent display body 5 by the operation of a solenoid 11 excited in the case when a lighting switch 12 is closed at night, etc. Therefore, the lighting to the periphery of the display body 5 at night, etc. is permitted, and the trouble that the shape of figures on the display body 5 becomes dim is prevented.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a display device for a vehicle, and particularly to a hand-held display.

[Prior art]

As a conventional vehicle display device, Japanese Patent Application Laid-Open No. 52-5763
There is Publication No. 3.

[Problems to be solved by the present invention]

However, with such conventional vehicle display devices, when the surroundings are dark, such as at night, the glowing segments illuminate the surrounding area, making the fonts of the fluorescent display blurry and reducing visibility. I needed to improve. or,
To prevent the surrounding area from being illuminated,
When a smoke lens is used to cover the fluorescent display tube unit, there is a problem in that it is dark during the daytime when the lighting switch is not set to ONL, and the shapes of the fluorescent display cannot be seen.

Therefore, the object of the present invention is to enable direct viewing of the fluorescent display when the surroundings are bright, such as during the day, and to cover the fluorescent display with a smoked lens in conjunction with a lighting switch when the surroundings are dark, such as at night. It is said that

[Configuration of the present invention]

In order to achieve this object, the present invention uses a fluorescent display tube unit built into an instrument panel and a lens provided in an opening of the instrument panel facing the fluorescent display of the unit to form an image on the front windshield. In the display device, the fluorescent display tube unit is configured such that a smoke lens is superimposed on the display body when the lighting switch is turned on, and the display body is exposed when the lighting switch is turned off.

[For production]

Therefore, with the above configuration, when the surroundings are bright, the smoke lens does not cover the fluorescent display and can be visually recognized as is, and when the surroundings are dark, the smoke lens covers the fluorescent display and the letters can be accurately recognized. It is something.

〔Example〕

Next, the configuration of an embodiment of the present invention will be explained using FIG. 1 and FIG. 2.

In the figure, 1 is the front windshield, 2 is the eye range (the driver's eye area), 3 is the instrument panel, 4 is the fluorescent display tube unit built into the instrument panel 3, and 5 is the fluorescent light of the unit 4. Display body (segment), 6
is an opening provided on the upper surface of the instrument panel 3; 7 is a lens provided in the opening 6; 8 is a smoke lens mounted on the unit 4 via a bracket 9; 10 is a bracket 9 supported on the unit 4. 11 is a solenoid fixed to the bracket 9, 12 is a lighting switch, 13 is a battery, and 14 is an image displayed by the unit 4.

Therefore, when the surroundings are bright, such as during the day, Figures 1 and 2
As shown in the figure, the light from the fluorescent display 5 directly passes through the lens 7.
In order to focus the image on the front windshield 1 through the
Ensures sufficient brightness.

When the lighting switch 12 is turned on when the surroundings are dark, such as at night, the solenoid 11 is activated and the bracket 9 is operated, and the smoke lens 8 is superimposed on the fluorescent display 5, allowing correct display. Become.

〔effect〕

As described above, according to the present invention, it is possible to obtain a display device that always has excellent visibility regardless of changes in ambient brightness.
