Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a transilluminated display board used, for example, in automobile instruments.

[Background of the idea]

An example of a conventionally used transilluminated display panel of this type is the one shown in FIG. That is, in this conventional transmissive illumination type display board, characters, scales, etc. 2 on the surface of a transparent substrate 1 are printed in white or a semi-transparent light color of another color, and furthermore, the characters, scales, etc. Part 3 is printed in black or another color that does not transmit light, and during the day, letters, scales, etc. 2 are displayed using external light (reflected light), and in dark places such as at night, By lighting up an internal light source placed on the back side of the display board, the characters, scales, etc. 2 are illuminated semi-transparently.

However, in the case of such conventional transmissive illumination type display boards, there is a strong contrast between semi-transparent light parts such as letters and scales and non-transmissive parts during transmissive lighting such as at night. The problem was that there was a lot of glare in some parts, which caused driver's eyes to get tired.

[Purpose of invention]

The present invention was developed by focusing on such conventional problems, and in a transilluminated display board, the semi-transmitted light portion near the periphery of characters, scales, etc. 2,
By forming the weak semi-transparent light portion which is weaker than the amount of transmitted light of the character scale etc. 2, the contrast of the characters, scale etc. 2 will be felt to be weak, and the transmitted illumination method can solve the above-mentioned conventional problems. It is possible to provide a display board.

[Example of idea]

The present invention will be explained in detail below based on the embodiments shown in FIGS. 1 to 3.

Reference numeral 4 denotes a meter storage frame, and a meter 5 is housed inside this meter storage frame 4. 6 is instrument 5
A transilluminated display board located in front of the
A pointer 8 is attached to the tip of a pointer shaft 7 that passes through the transmitted illumination type display plate 6. The structure of the above-mentioned transilluminated display panel 6 includes a substrate 9 made of a transparent material.
On the surface, a first translucent printing layer 11 of white color, for example, is formed in a substantially fan shape in the vicinity where display portions 10 such as letters and scales are to be provided. Then, the first
A second semi-transparent printing layer 12 of, for example, blue color is formed on the surface of the semi-transparent printing layer 11 of do. Next, the portions other than the first semi-transparent printed layer 11 and the second semi-transparent printed layer 12 are coated with an opaque printed layer 13 of black color, for example.
It is completed by forming. Note that reference numeral 14 indicates a light source provided within the instrument housing frame 4 for transmitting illumination of the transmissive illumination type display board 6.

In this way, the transmitted illumination type display board 6 according to this embodiment
The display portion 10 such as characters and scales is displayed by the light transmitted by the first semi-transparent printing layer 11, and the peripheral portion of the display portion 10 such as the characters and scales are displayed by the first semi-transparent printing layer 11. Since it is displayed with weak transmitted light due to polymerization with the second semi-transparent printing layer 12,
The contrast of transmitted light of the display unit 10 such as a scale is
This has the effect of being weakened by the transmitted light from the periphery, thereby increasing visibility.

In the above embodiment, the first semi-transparent printed layer 11 and the second semi-transparent printed layer 12 are provided, but the object of the present invention cannot be achieved even if the first semi-transparent printed layer 11 is omitted. However, in this case, it is desirable that the substrate 9 be made of a translucent material, such as milky white.

[Summary of the idea]

As described above, the present invention includes a translucent printed layer 12 that surrounds the display section 10 except for the display section 10 that displays numbers, characters, symbols, scales, etc. on the upper surface of the substrate 9 made of a translucent material. provided, the semi-transparent printing layer 12
and a transmissive illumination type display board characterized in that an opaque printed layer 13 is provided in addition to the display section 10.

[Effect of idea]

Therefore, according to this transilluminated display board, characters,
Since the peripheral parts of the display section 10, such as symbols and scales, shine with transmitted light that is weaker than the brightness of the display section, the contrast of the display section 10 is relaxed, making it easier for drivers etc. to see and preventing fatigue. There is an effect that can be done.

Claims (1)

[Scope of utility model registration request] A semi-transparent printed layer 12 is provided on the upper surface of the substrate 9 made of a translucent material and surrounds the display section 10 except for the display section 10 for displaying numbers, characters, symbols, etc., and the semi-transparent printed layer 12 and the display are A transmissive illumination type display board characterized in that an opaque printed layer 13 is provided in a portion other than the portion 10.
