Description of the Related Art Generally, when displaying using light emitting diodes, as shown in FIG. 2, a light emitting diode 1 is mounted on a printed circuit board 2, and opaque ink is printed in color on a transparent plate 4 facing the printed circuit board 2. In this structure, an opaque part and a window part through which light passes are provided, and the light from the light emitting diode 1 can be seen through the window part. When displaying a plurality of light emitting diodes side by side, and in order to prevent the light from the light emitting diodes 1 from leaking to other parts of the transparent plate 4, it was necessary to attach the light shielding plate 3 to the printed circuit board 2 from above the light emitting diodes 1. .

た。Problems to be Solved by the Invention However, since a display device using such light emitting diodes requires a light shielding plate 3, it is difficult to narrow the distance between the light emitting diodes when installing multiple light emitting diodes. Moreover, it was not possible to attach other parts near the light emitting diode, which caused a big problem in reducing the size and increasing the density of the entire device. Additionally, if a component taller than the light-emitting diode is installed on the same side as the light-emitting diode, the distance between the printed circuit board and the transparent plate on the front surface, that is, the distance from the light source of the light-emitting diode increases, resulting in a reduction in brightness. had.

By printing opaque ink on the opposite side of the printed circuit board, the printed circuit board itself can be used as a light shielding plate. Therefore, a light-shielding plate is not required, the distance between the printed circuit board and the transparent plate on the front surface can be narrowed, and other parts can be attached around the light emitting diode. Furthermore, when a plurality of light emitting diodes are mounted, the mounting interval can be reduced. Furthermore, when printing this opaque ink, a service map can also be printed at the same time.

同時に印刷することができる。 As shown in FIG. 1, a light emitting diode 1 is attached to a printed circuit board 2 by processing terminals so that the light emitting surface faces the printed circuit board. Printed circuit board 2
A hole 2a is formed at a position centered on the light source portion of the light emitting diode 1, and an opaque ink layer 5 is provided by printing opaque ink around the hole 2a on the opposite side to where the light emitting diode 1 is attached. . A transparent panel 4 is attached thereon. In this way, since the printed circuit board 2 acts as a light shielding plate due to the opaque ink layer 5, the range of the light source of the light emitting diode can be determined by the hole 2a provided in the printed circuit board 2 and the printed part on the transparent panel. Light leakage to other parts can be prevented, and a light shielding plate can be eliminated. Furthermore, the distance between the printed circuit board 2 and the transparent panel 4 can be reduced. Furthermore, other components 6 can be mounted close to the light emitting diode 1. Note that the opaque ink layer can be printed simultaneously with the copper foil insulation layer or service map of the printed circuit board.

事もでき、実用上極めて有利なものである。Effects of the Invention As described above, the present invention has a structure in which the light-emitting diode is mounted with the light-emitting surface facing the surface of the printed circuit board, and a transparent plate is attached to the surface opposite to the mounting surface. A hole is provided and the light from the hole is used as a light source for display, and the distance between the printed circuit board on which the light emitting diode is attached and the outer transparent plate can be reduced. Further, even when a component higher than the light emitting diode is mounted on the printed circuit board, the distance from the light emitting diode light source to the transparent plate does not change, and brightness is ensured. By printing an opaque ink layer around the hole on the opposite side of the printed circuit board from where the light emitting diode is mounted, the printed circuit board itself can be used as a light shielding plate to prevent light scattering and leakage from the light emitting diode. You can focus the light on the area you want to display. Furthermore, by eliminating the light shielding plate, other parts can be mounted close to the light emitting diode, making it possible to downsize and increase the density of the entire device. The opaque ink layer can be printed simultaneously with the copper foil insulating layer and the service map, which is extremely advantageous in practice.
