Abstract

PURPOSE:To create color gradation effect and sensation of three dimensions by providing a display of a scale, etc., on the surface of a transparent plate by the coloring of a fluorescent material, and then providing a translucent material which varies in plate thickness vertically and continuously and a colored material. CONSTITUTION:The display 1a of a scale, etc., is printed on the surface of the transparent plate 1 in ink of the fluorescent material, and then the transparent or translucent plate 2 which varies in plate thickness vertically and continuously and the cemented body of the colored plate 3 with light transmittivity and a photoconductor 4 are provided. Then, a pointer 6 colored with a fluorescent material, the transparent plate 1, and an ultraviolet-ray lamp 5 which allows the pointer 6 to luminesce are provided in front of the transparent plate 1. Thus, the display 1a of the scale, etc., and the colored surface other than the display 1a are not on the same plane unlike a conventional device and separated from each other, so that the color gradation effect and sensation of three dimensions are created.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a display device for a combination gauge meter for an automobile.

Conventional combination meters print patterns such as the background color, scale, and numbers on acrylic or polyurethane, and the pointer moves on top of that, making it possible to print with a design effect or create a three-dimensional effect. Have difficulty.

The present invention has been made with attention to the above-mentioned points of view, and its purpose is to apply various shading processes, which are difficult with conventional printing, to the area corresponding to the background color, and to print scales, numbers, etc. The purpose is to create a color shading effect and a three-dimensional effect by laying it out apart from the panel. In addition, for night lighting, by irradiating light from the front of the transparent plate with a lamp, lighting with a three-dimensional effect and a sense of depth that could not be achieved conventionally can be realized.

The present invention will be described below with reference to embodiments shown in the drawings.

Figures 1 and 2 show the application of the present invention to an automobile combination meter. Indications 1a such as scales are printed on the surface of a transparent plate 1 with fluorescent ink, and then the plate thickness is adjusted up and down. A transparent or semi-transparent plate 2 having a translucent property that changes continuously in the direction, a colored plate 3 having a translucent property, and a light guide 4 are provided, and the front part of the transparent plate 1 is coated with a fluorescent substance. A colored pointer 6, a transparent plate 1, and an ultraviolet lamp 5 for making the pointer 6 emit light are provided. Further, an illumination lamp 7 is provided on the rear side of the light guide 4.

Since this embodiment has the above-described structure, the display 1a such as a scale and the colored surface other than the display 1a are not on the same plane as in the conventional display device, but can be configured in a separate state (transparent plate Separation of 1 and 2) Furthermore, the display on the front side of transparent material 1 and the pointer 6
and are colored with fluorescent substances, so they can be seen during the day and at night (
Not only can the display color be changed (when lamp 5.7 is off and on), but when lamp 5 is on, it becomes a very clear and beautiful display, improving visibility and readability. Significant improvements can be achieved.

In this embodiment, the thickness of the semi-transparent plate 2 is changed continuously in the vertical direction in order to further enhance the three-dimensional effect and perspective created by separating the transparent plates 1 and 2. The coloring density of the colored plate 3 appears to change continuously from the upper side of the semi-transparent plate 2 where the plate thickness is thicker to the lower side where the plate thickness is thinner. A similar effect can be obtained by continuously changing the plate thickness from the top to the top.

Further, light from lighting of the illumination lamp 7 is guided to the light guide 4 and illuminates the colored plate 3 through the light.
