Problems solved by technology

However, due to the method of making a part of the display panel 1 three-dimensionally protruded and molding the display panel, the deformation of the index letters printed on the back side during molding is affected, or due to the influence of the shrinkage of the molding material, forming on the display panel 1 Unnatural lines, so the method is not preferred

[0032] The following will refer to Figure 1 to Figure 6 The first embodiment is described in detail. figure 1 is a front view of the vehicle meter according to the first embodiment. The display panel 1 is made of transparent acrylic resin, which is called a molded dial, and is positioned on the figure 1 The back of the display panel is flat on the inner side of the plane. The surface of the display panel 1 is molded in a gently curved shape. Meanwhile, the curved shape of the surface is not necessary.

[0033] As in Patent Document 1, the display panel 1 is illuminated by edge lighting that introduces illumination light into the display panel 1 from the edge portion 3 of the display panel 1 on which the scale 2 is formed. The pointer 4 rotates on the display panel 1 , and the end of the pointer points to a numeral portion forming an indication portion 5 in particular. Index letters including at least the indicator portion 5 are printed on the back side of the display p...

[0060] Next, a second embodiment will be described. Meanwhile, the same components as those of the above-described first embodiment are denoted by the same reference numerals, descriptions thereof will be omitted, and structures and characteristics different from the above-described first embodiment will be described in the following embodiments. Figure 7 is a front view of a part of the vehicle meter according to the second embodiment.

[0061] and Figure 5 The inclined surface 10 of the V-shaped cutout 5b1 identical to the V-shaped cutout shown in , is colored red in this second embodiment, so that the V-shaped cutout 5b1 is shown in red. Therefore, a stereoscopic display that changes between daytime and nighttime can be realized. Specifically, since the inclined surface 10 of the V-shaped cutout 5b1 emits red light at night using illumination light emitted from the LED 8 and introduced into the display panel 1, display with a sense of tension can be implemented.

[0067] Next, a third embodiment will be described. Characteristic portions different from the above-described embodiments will be described. Figure 9 is a front view of a part of the vehicle meter according to the third embodiment. Figure 10 yes Figure 9 The enlarged front view of a part of "20" and "40" of the indication part 5 in the area X. exist Figure 10 In , the V-shaped cutout 5b1 surrounds the entire periphery of the indicating portion 5 with a single stroke.

[0068] Each of the indicating portions 5 includes a numeral indicating portion 5 a that is printed on the back side of the display panel 1 and indicates numerals. In addition, each of the indicating portions 5 includes a stereoscopic display portion 5b that allows the numerical indicating portion 5a to be seen stereoscopically so as to surround the periphery of the numerical indicating portion 5a. The stereoscopic display portion 5 a is formed by an annular ring on “ 20 ” which is, for example, one indi...

Abstract

A vehicle instrument utilizing edge light illumination, the edge light illumination introduces illumination light into the display panel (1) from a side edge portion (3) of a display panel (1) on which scales (2) are formed, the The vehicle instrument includes indicator letters arranged on the inner side of the display panel (1) and formed by indicating portions (5). The indicating part (5) includes: at least one digital indicating part (5a), which is printed on the inner side of the display panel (1) and indicates numbers; and a three-dimensional display part (5b), which is arranged on the digital indicating part (5a ) at the position of the shadow of ), and make the number indicator (5a) visible three-dimensionally. The stereoscopic display portion (5b) is formed by a V-shaped cutout (5b1) including an inclined surface (10) recessed from the back side of the display panel (1) to the surface side of the display panel. Illumination light of edge lighting is reflected on the inclined surface (10), so that the three-dimensional display part (5b) allowing the indication part (5) to be visible three-dimensionally emits light at night.
