BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mounting structure of a display device on a panel surface, and in particular, for example, an LCD illuminating from the back of the display device.
The present invention relates to a display mounting structure suitable for mounting such as

[0002]

2. Description of the Related Art Conventionally, many mounting structures for a display device, for example, an LCD, as shown in a sectional view of FIG. 2, have been provided. In the figure, 1 is a panel, 1c is a mounting boss for mounting the panel 1 on a printed circuit board, 2 is an LCD mounted on the panel 1 surface,
3 is a light guide plate provided on the back of the LCD 2, 3 a is a light guide plate 3
4 is a light source mounted on the printed circuit board and provided near the notch 3a of the light guide plate 3, 5 is a rubber connector connecting the LCD 2 and the printed circuit board, and 6 is printed on the mounting boss 1c of the panel 1. A screw for attaching the board, 7 is a printed board, and 10 is a holder for holding the display 2.

[0003] The L attached to a predetermined position of the panel 1
The CD 2 is firmly fixed by a substantially U-shaped holder 10 soldered to the printed board 7, and is illuminated from the back of the LCD 2 by the light source 4 attached to the printed board 7 via the light guide plate 3. The printed circuit board 7 is mounted on the mounting boss 1c of the panel 1 with screws 6.

On the other hand, input / output terminals of the LCD 2 are protected by a rubber connector 5 and are wired on a copper foil pattern of a printed circuit board 7, and various displays can be performed by the back-lit LCD 2.

[0005]

However, in the above-described conventional display mounting structure, the display 2 and the light guide plate 3 are fixed by the holder 10, and the holder 10 is mounted on the printed circuit board 7 by soldering. In addition, there is a disadvantage that the assembly work is difficult, the number of production steps is increased, and the production cost is increased.

In addition, since it is mounted with the holder 10, the number of parts is increased and the material cost is increased.

The present invention has been made in view of the above points, and aims at solving the drawbacks of the conventional example and providing a fixing boss having a hook for fixing the display 2 and the like inside the panel 1. It is an object of the present invention to provide a display mounting structure with high productivity in display assembly.

[0008]

According to the present invention, there is provided a display mounting structure in which a light source is provided in a cutout portion of a light guide plate provided on the back of a panel display, and the light source illuminates the display. A fixed boss provided inside the panel of the display mounting portion, and a hook formed on the fixed boss, and the notch of the light guide plate is engaged with the hook to connect the display and the light guide plate to the panel. It is configured to be positioned and fixed.

[0009]

According to the present invention, fixed bosses are provided inside the panel of the display mounting portion, for example, at the upper and lower positions of the display, and protruding hooks are provided near the center of the fixed boss to overlap the display. The hook is engaged with the notch of the light guide plate to be attached together.

That is, a display illuminated via a light guide plate with light from a light source attached to a printed circuit board is sandwiched between the printed circuit board and the panel so as to overlap the light guide plate, and the hook of the fixed boss is provided. The light guide plate and the display are pressed against the panel.

Further, the printed circuit board is screwed to a mounting boss of the panel, and input / output terminals from the display are wired to the printed circuit board by a rubber connector, and the back illuminated display is mounted on the panel. The number of parts can be reduced for the mounting structure of the display, and the production cost can be reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a display mounting structure according to the present invention will be described with reference to the sectional view of FIG. The same parts as those in the conventional example are denoted by the same reference numerals, and description thereof will be omitted.

In the figure, reference numeral 1a denotes a fixed boss provided on the display 2 mounting portion of the panel 1, and 1b denotes a hook provided near a substantially central portion of the fixed boss 1a. The hook 1b has a protruding shape as shown in the figure. And is engaged with the notch 3a of the light guide plate 3,
And press the display 2 against the panel 1.

As described above, the display 2 and the light guide plate 3, which are attached to the panel 1 by being pressed against the panel 1 by the hooks 1b of the fixing boss 1a, are sandwiched between the printed circuit board 7 and the printed circuit board 7 as in the conventional example. The screw 6 is fixed to the mounting boss 1c of the panel 1.

On the other hand, the light source 4 mounted on the printed circuit board 7 is disposed in the notch 3a of the light guide plate 3, and the light from the light source 4 is attached to the light guide plate 3 in close contact with the light guide plate 3 via the light guide plate 3. The entire display 2 can be illuminated from the back.

As described above, for example, the resin molded panel 1
By generating a plurality of fixed bosses 1a having hooks 1b therein, components for mounting the display 2 and the light guide plate 3 (such as a conventional holder) are not required, and the assembling work is facilitated.
Moreover, the display 2 can be attached to the panel 1 in close contact.

[0017]

According to the present invention, the mounting structure of the display device according to the present invention can position and fix the display device and the light guide plate with respect to the panel by the hook of the fixing boss provided on the panel. Points can be reduced.

In addition, since assembly can be performed only from the back side of the panel and screwing is not required, the operation can be simplified.

Therefore, productivity can be improved.
