Abstract

PROBLEM TO BE SOLVED: To provide display device capable of improving visibility of the display (numerical values) formed on a display board of a meter or the like for an automobile. SOLUTION: In a vehicle speed display 12, graduations 14 for vehicle speed display are formed on a circular arc whose center is a pointer shaft insertion hole 13 bored in a dial 11. In these main graduations 14, display numerical values 15 are formed. The display numerical values 15 in this practical mode have twenty numerical value intervals, so that display figures showing speeds per hour of 0, 20, 40, 60, 80, 100, 120, 140, 160 and 180 are formed. A zero display of each of the first digits of the display numerical values 15 showing the speed per hour uses a figure having a size smaller than the sizes of figures of a second digit and a third digit.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device provided, for example, in front of a driver's seat in a vehicle cabin. The present invention relates to a display device having a display form that can be improved.

[0002]

2. Description of the Related Art A dial and a display value (numerical value) displayed on a dial of a general analog display device used for an instrument for an automobile have a dial 1 as shown in FIG. In addition, there are provided a speedometer 2 for displaying a vehicle speed, a tachometer 3 for displaying an engine speed, a fuel gauge 5 for displaying a remaining fuel amount, and a thermometer 4 for displaying an engine temperature. .

A scale 6 corresponding to the speedometer 2 and the tachometer 3 is provided along a circumference drawn around a pointer shaft 8 for indicating the hands 2A and 3A. Value 7 of speedometer 2 corresponding to
Is displayed in two- and three-digit numbers with a numerical interval of 20,
In addition, the display value 7 of the tachometer 3 is displayed with only the first digit of the highest digit 0 to 8 corresponding to the scale, and the lower three digits are simply displayed as a magnification display (× 1000). That is, the display value 7 in the speedometer 2 is a numerical value of 2 to 3 digits,
The display value 7 in the tachometer 3 is a one-digit numerical value.

As described above, the number of digits displayed on the speedometer 2 is two to three digits, and the number of digits displayed on the tachometer 3 is one digit. , The discrimination between the speedometer 2 and the tachometer 3 is facilitated, and the misreading of the speedometer 2 and the tachometer 3 by mistake can be eliminated.

[0005]

However, in the speedometer 2 using a numerical value of 2 to 3 digits, a numerical value of 2 to 3 digits is set within a designated area (display area) of a limited size. If a large number of numerical displays are to be performed by using the numerical display, the size of the numerical display is limited, and the size of the numerical display is naturally reduced. When the size of the numerical display is reduced, there is a problem that the numerical display of the speedometer becomes difficult to see for a driver with reduced visual acuity, such as the elderly.

The present invention has been made in view of such conventional inconveniences. In particular, in a display mode of an instrument for displaying a numerical value with two or more digits, at least the first digit is displayed small and the remaining two digits are displayed. It is an object of the present invention to provide a display device in which a digit or a third digit is displayed in a large size to improve the readability and readability of a numerical value, and to clarify a display distinction from another display instrument adjacent thereto. .

[0007]

According to a first aspect of the present invention, there is provided a display device for an instrument dial for displaying a numerical value of two or three digits at a desired numerical interval. The display device is characterized in that the size of the first digit of the display numerical value is set smaller than the sizes of the second and third digits.

According to a second aspect of the present invention, in addition to the first aspect, the present invention is directed to a display device in which the numeral color of the first digit display is set to be different from the second and third digit display colors. Features.

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

Reference numeral 11 denotes a transmission illumination type or reflection type dial used for a display device. The dial 11 is provided with a vehicle speed display 12 corresponding to a pointer of a vehicle speed indicator (not shown). The left and right sides of the vehicle speed display 12 are provided with the same rotation display (not shown), fuel display, and temperature display (not shown) as shown in the conventional example of FIG. In this embodiment,
Since the present invention is characterized by a vehicle speed display in which the displayed numerical value is displayed in two or three digits, the vehicle speed display 12 will be described in particular.

The vehicle speed display 12 is provided with scales 14 for displaying the vehicle speed on an arc line centered on the pointer shaft insertion hole 13 formed in the dial 11 and these main scales 14 are provided. , The display numerical value 15 is given. The display numerical value 15 in this embodiment is given at a numerical interval of 20, so that 0, 20, 40, 60, 80, 10
The display numbers indicate the speeds of 0, 120, 140, 160, and 180. And the display numerical value 1 which shows those speed
The zero display of the first digit of 5 is characterized in that it is displayed with a number smaller than the size of the second and third digits.

By setting the size of the first digit of the display numerical value 15 to be smaller than the sizes of the second and third digits, the vehicle speed display 1 in a limited display space can be obtained.
Since the size of the second and third digits of each numerical value 15 to be displayed in the two parts can be relatively large, the vehicle speed numerical value 15 becomes easy to see, and especially the visual acuity of the elderly and the like. For a viewer who has reduced the display, the display is excellent in instantaneous readability and legibility.

The number of display digits of the vehicle speed display value 15 is as follows:
Since the display is two or three digits as before,
It is possible to prevent erroneous reading of numerical values without misunderstanding as a display value of an adjacent tachometer or the like.

It is also possible that the color of the first digit set smaller than the size of the second and third digits is different from the color of the second and third digits. Again,
The color can be easily distinguished from an adjacent tachometer, etc., so that erroneous reading can be prevented, and instantaneous readability and legibility are further improved. Further, by forming the line width of the first digit set smaller than the size of the second and third digits to be narrower (thinner) than the second and third digits, applicability is further improved. I do.

[0015]

As described above, according to the display device of the present invention, it is possible to display the second and third digits of the numerical value to be displayed in two or three digits in large numbers. This makes it possible to provide a display device with excellent instantaneous readability and legibility, and also clearly distinguishes display from an adjacent display device, thereby preventing misreading.
