Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a display device which is frequently used in a small information processing device such as a notebook type personal computer or a laptop type personal computer.

[0002]

2. Description of the Related Art Generally, in a display device which is rotatably mounted on an information processing device body so as to show a display surface when in use, a back cover of the display device is mounted on the information processing device body in an unused state. In order to configure the outer shell, it is necessary to consider so that the display unit such as the liquid crystal unit is not damaged by the stress load on the back cover.

Conventionally, as a display device satisfying such a need, a display device having a structure shown in FIG. 3 is widely used. That is, in this conventional example, the mica plate 8 is interposed between the back cover 2 and the display unit 3 such as a liquid crystal unit fixed to the front cover 1 via the mounting bracket 7, and the back cover 2 is attached to the back cover 2. Absorption of impact force or back cover 2
Dispersion of the point load applied to the can be achieved.

[0004]

On the other hand, in the above-mentioned conventional example, although the display unit 3 has a standardized effective display area of the display panel 30, the outer shape of the entire display unit 3 including the control board 31 and the like. The dimensions, thickness, etc. differ depending on the manufacturer, etc., and it is difficult to apply a process to imitate the display unit 3 on the surface of the mica plate 8. Therefore, when a point load test is carried out by mounting it on an actual machine, a concentrated load site is generated at the boundary of the control board 31 or near the fixed portion of the display unit 3 to the front cover 1. There is a problem that the display panel 30 is broken.

In order to solve such a problem, conventionally, another reinforcing auxiliary member 9 is intervening in a physical manner based on a load test result.
Alternatively, there is a drawback in that the workability of manufacturing is extremely poor because management of combinations is required.

The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide a display device of an information processing device which has good manufacturing workability and whose display unit is surely reinforced. And

[0007]

According to the present invention, the above object is to provide a display panel 30 of an information processing apparatus in which the front and back covers 1 and 2 cover the display unit 3, and to provide the back cover 2 and the display unit 3. In between, a panel support portion 40 that supports the back surface of the display panel 30 of the display unit 3 and a substrate support portion 4 that supports the back surface of the control board 31 of the display unit 3.
It is achieved by providing a display device of an information processing device in which the reinforcing body 4 is integrally provided with 1 and 1 and having a positioning portion 42 that fits with the positioning portion 20 provided on the back cover 2.

The reinforcing member 4 in the present invention has a predetermined rigidity,
Alternatively, a material, such as a synthetic material, which has strength and is excellent in formability or workability so that a surface state having unevenness can be obtained so as to contact almost the entire area of the display unit 3 including the control board 31. It is made of a resin material.

A panel support portion 40 that supports the rear surface of the display panel 30 and a substrate support portion 4 that supports the rear surface of the control board 31.
By integrally forming 1 and 1, the point load applied to the back cover 2 becomes a force that uniformly presses the entire display unit 3, and concentrated load on the display panel 30 is prevented.

In the second aspect of the present invention, the reinforcing body 4 is formed by fixing the mica plate 6 on one surface of the mold portion 5 made of a synthetic resin material. By forming the reinforcing body 4 by combining the mold portion 5 that is easy to mold and the mica plate 6 that is lightweight and has high strength, the reinforcing body 4 that is lightweight and that can disperse the force to the entire display unit 3 can be obtained. Obtainable.

In the invention according to claim 3, the reinforcing member 4
Is formed in at least an area that can be overlapped with the fixed portion of the display unit 3 on the front cover 1. When the area of the reinforcing member 4 is increased to such an extent that it overlaps with the fixing portion of the display unit 3 on the front cover 1, the load from the back cover 2 becomes a force for pressing the entire display unit 3 against the front cover 1. In addition, stress concentration on the display panel 30 is further prevented.

[0012]

BEST MODE FOR CARRYING OUT THE INVENTION As shown in FIG. 1, a display unit 3 includes a front cover 1 having a display opening 10 in the center thereof.
A display unit 3 such as a liquid crystal unit which is arranged with its display surface exposed from the display opening 10 of the front cover 1, a back cover 2 joined to the front cover 1 at the peripheral portion, and a back cover 2
And a reinforcing body 4 interposed between the display unit 3 and the display unit 3.

The display unit 3 comprises a control board 31 and a display panel 30 such as a liquid crystal panel.
0, or the mounting bracket 7 fixed to the control board 31 is fixed to the front cover 1 with screws or the like.

The reinforcing member 4 is a molded product formed of a synthetic resin material or the like, and is a substrate supporting member 41 on the side of the panel supporting member 40 that abuts the back surface of the display panel 30 of the display unit 3.
Are integrally formed. Further, the reinforcing body 4 is formed with a concave portion (positioning portion 42) for positioning at an appropriate position, and by fitting it into a positioning boss (positioning portion 20) protruding from the back cover 2 side, a predetermined position can be obtained. Be positioned at.

The area of the reinforcing member 4 is preferably as large as possible, and the display unit 3 is at least seen in a plan view.
It is formed in such a size that it can be overlapped with the mounting bracket 7. The reinforcing body 4 can be formed entirely of a synthetic resin material, but can also be formed by attaching a mica plate 6 to one surface of the mold portion 5 as shown in FIG. Yes, in this case, to reduce the overall weight,
The board-shaped ribs 50, 50 ... May be formed on the surface of the mold portion 5.

[0016]

As is apparent from the above description, according to the present invention, it is not necessary to select and use a reinforcing auxiliary material for each display unit manufactured by a maker, so that manufacturing workability is improved, In addition, it is possible to reliably prevent stress concentration on the display panel of the display unit.
