Abstract

PURPOSE:To improve the visibility of a liquid crystal display part even if the solar light is front or rear, by opening light-transmittably the rear side of the display part and conducting the solar light to the rear side. CONSTITUTION:A liquid crystal cell body 12 of a liquid crystal display part 11 wherein a liquid crystal is sandwiched between glass or plastic plates is supported with a liquid crystal cell support part 13. A semitransparent reflection plate 12a is provided on the rear of the body 12, and the front and rear sides are protected with light transmittable protective plates 14 consisting of glass or plastic plates. The rear side of the display part 11 is light-transmittably opened and the liquid crystal display part is mounted to a frame body 15. If the solar light is the front light S2 that irradiates the vehicle from behind the same, segments 26 are dark by absorbing the light reflected by the plate 12a and a margin part 27 is bright by reflecting the solar light, thus making the display distinctly visible. In the case of rear light S1, the segments 26 are silhouetted and are dark by absorbing the light on the front side and the part 27 is brightly visible by allowing the transmission of the solar light.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal meter for a motorcycle that has good visibility and has a modern feel.

Liquid crystal meters have started to be adopted for vehicles, mainly in four-wheeled vehicles and motorcycles, because they match modern sensibilities, consume little power, and can be installed in any location. There is. However, conventionally, as shown in FIG. 1, a liquid crystal meter installed in a motorcycle has a meter case 3 attached to a top bridge 5 above a front fork 4 in front of a steering handle 2 of a vehicle body 1 of the motorcycle. , a liquid crystal display section 6 of a liquid crystal meter is provided on the front surface of the meter case 3.

A screen 7 made of a glass plate or a transparent plastic plate for night illumination and a lighting moon 8 are installed on the back side of the liquid crystal display section 6, and an electric circuit section 9 is housed inside the meter case 3, and the liquid crystal cells of the liquid crystal display section 6 are housed inside the meter case 3. electrically connected to.

In such a liquid crystal meter, the liquid crystal, which does not have self-luminous properties, is illuminated by sunlight shining on the front surface of the liquid crystal during the day, and from twilight to night by the illumination light from the back.

The present invention provides an LCD meter for a motorcycle that is attached to the front of the motorcycle body and whose front surface is oriented toward the rear of the motorcycle body. By guiding sunlight to the back side of the
[During the day when sunlight is shining brightly.

Or make the display clear even when backlit,
(2) We offer a liquid crystal meter for motorcycles that has a sleek appearance due to the ability to separate the electrical circuit section.

Embodiments of the present invention will be described below based on the drawings.

FIG. 2 shows a vertical cross-sectional view of a liquid crystal meter, in which the liquid crystal display section of the liquid crystal meter 10]l shows a liquid crystal cell main body 12 with a liquid crystal sandwiched between glass plates or plastic plates, supported by a liquid crystal cell support part 13, and a liquid crystal display part of the liquid crystal meter 10. A transflective plate L2a is provided on the back surface of the cell body 12. In addition, the front and back sides are transparent protective plates 14 made of glass or plastic plates.
The liquid crystal display section 11 is attached to the frame body 15 with its back side opened to allow light to pass through. Furthermore, the frame body 15
The second part has a canopy 16 for making it easier to see the liquid crystal display section 11.
is formed.

Fig. 3 shows an example in which the liquid crystal display unit 11 as shown in Fig. 2 is mounted on a standard motorcycle. 15 is removed (=J is removed, the back side of the liquid crystal display section 11 is open, and the sun is in front of the vehicle body 1 and backlight S
In the case of , the back surface of the liquid crystal display section 11 is directly irradiated with sunlight. A night illumination light 18 is provided on the back side of the headlight 17 to illuminate the liquid crystal display section 11 from the back side. Further, the electric circuit section 19 is connected to one side of the display panel 20 by a wiring 21 for moving the liquid crystal display section 11.

Figure 4 (Tsuko's LCD meter 1 ())
1'! An example is shown in which it is mounted on a vehicle, in which a headlamp 17 and a windshield 22 are installed in front of the di body 1, and a meter space 24 is installed inside the fair link 23 which is cut out. A liquid crystal display section 11 is fitted into the front surface. In this case, the two-part eave 16' is formed as a part of the meter case 24. Then, the surface of the fair link 23 facing the back surface of the liquid crystal display section +1 is opened 1-1, the transparent plate 25 is fitted therein, and when the sun is in front of the vehicle body 1 and jφ light S1, sunlight is guided to the back surface of the liquid crystal display section 11 through the transparent plate 25. The electric circuit section 19 is housed within the meter housing 2'l and is connected to the city pole wiring 21, and a night illumination device 118 is provided within the meter housing 24.

In such a liquid crystal display section 11, in the case of front light S2 in which the daytime sun illuminates the rear of the vehicle body, the segments 26 of the liquid crystal display section 11 shown in FIG. The blank space 27 is bright by reflecting sunlight, and the display of Setamen 1-26 can be clearly seen. Conversely, in the case of backlight S where the sun shines from the front of the vehicle body, on the front side of the liquid crystal display section 11, the segment 2G absorbs light and becomes a dark silhouette, and the margin section 27 transmits sunlight and becomes bright. Again, the display of segment 26 can be clearly seen.

As described above, according to the present invention, the back side of the liquid crystal display section is opened to allow light to pass through, and sunlight is guided to the back side of the liquid crystal display section. Alternatively, it is possible to provide a liquid crystal meter for a motor vehicle that improves the visibility of the display section even in backlight conditions and that matches modern sensibilities.
