Description

  The present invention relates to a thin display.

In the prior art disclosed in Patent Document 1, an insert nut for attaching a wall hanging bracket is embedded on the rear side of the rear cabinet.
In the prior art disclosed in Patent Document 2, wall mounting is possible by changing the mounting direction of the stand with respect to the rear cabinet.
In the prior art disclosed in Patent Document 3, a bridge-shaped structure is attached in parallel to the back surface of the display panel while being vertically oriented.

FIG. 5 is a perspective view showing an internal configuration of a conventional example.
The figure shows a front cabinet 10, an opening 10a, a rear cabinet 11, a mounting screw hole 11a, a display panel 12, a first frame member 13, a second frame member 14, a PCB 15, and a stand 16.
Next, these will be described.
The front cabinet 10 and the rear cabinet 11 are combined to form a housing that can accommodate the display panel 12 therein. Four mounting screw holes 11a for fixing a wall mounting bracket (not shown) are formed in the center of the rear surface of the rear cabinet 11.

Two bridge-shaped first frame members 13 are attached to the back surface of the display panel 12 in parallel, and the second frame member 14 is attached so as to connect the two. The stand 16 is fixed to the display panel 12 and supports the display panel 12.
In FIG. 5, two parallel first frame members 13 oriented in the vertical direction are provided on the back surface of the display panel 3, and a second frame member 14 is connected between them. The PCB 15 is accommodated between the first frame member 13, the second frame member 14, and the display panel 12.

  According to safety standards, the minimum distance between the electronic component on the PCB 15 and the first frame member 13 or the second frame member 14 is determined. Therefore, in the configuration in which the second frame member 14 is positioned so as to cover the back side of the PCB 15, the overall thickness inevitably increases, and there is a limit to thinness. Moreover, the structure which requires the 1st frame member 13 and the 2nd frame member 14 is not simple, and cost also rises.

The technique disclosed in Patent Document 1 has a problem that it can be used only for a small display that can be supported by a rear cabinet.
In the technique of Patent Document 2 described above, there is a problem that only the mounting direction of the stand can be changed, and the support structure itself adopts the conventional configuration.
In the technology of Patent Document 3 described above, since the structure straddles the main substrate, the height of the main substrate is limited, and two bridge-shaped structures are required, resulting in a complicated structure. was there.

  An object of the present invention is to simplify a wall-hanging structure and relax a substrate height restriction.

  In order to solve the above problems, in the present invention, a front cabinet having a display surface opening and formed in a frame shape on the front side of the housing, and a rear cabinet formed in a thin box shape on the back side of the housing. And a thin display panel that has a display surface on the front side, is covered with a metal case on the back and side surfaces, and is exposed to the opening of the front cabinet while being housed in a housing composed of the front cabinet and the rear cabinet. A PCB plate attached to the rear surface of the thin display panel, a main substrate serving as a control substrate for the thin display panel, one end attached to the PCB plate, extending substantially vertically toward the rear side, and the other end of the rear plate Attach to the cabinet and screw it to the external wall bracket with the rear cabinet in between It is constituted comprising a bearing member formed of ability of the internal thread hole.

  In this invention comprised as mentioned above, a front cabinet and a rear cabinet unite | combine from the front-back direction, and form a housing. The housing contains a thin display panel inside. The thin display panel includes a PCB plate for holding the main substrate on the back side. The PCB plate includes a bearing member, and protrudes substantially vertically toward the back surface side. The bearing member reaches the rear cabinet, and when the wall is hung, a wall-hanging metal fitting is disposed on the rear side of the rear cabinet, and is screwed and fixed to a female screw formed at the tip of the connecting member with a male screw.

In another aspect of the present invention, the main substrate has an avoidance hole that allows the bearing member to pass therethrough.
In the present embodiment configured as described above, since the bearing member is erected on the PCB plate, the size of the main substrate is limited as it is. However, by providing an avoidance hole that can penetrate the bearing member, the bearing member is penetrated through the avoidance hole, and the main substrate is fixed on the PCB plate.

In another aspect of the present invention, the bearing member has a substantially cylindrical shape.
In this aspect configured as described above, one end of a substantially columnar shape is fixed to the PCB plate, and is fixed to an external wall hanging bracket by a female screw formed at the other end.
In another aspect of the present invention, the bearing member is configured to be fitted and fixed to the PCB plate by caulking.

In the present embodiment configured as described above, after one end of the bearing member is disposed at a predetermined position on the PCB plate, the two are crimped and fixed.
In another aspect of the present invention, the bearing member is formed by bending a metal plate.
In this aspect configured as described above, the metal plate is bent so that one end can be fixed to a predetermined position on the main substrate and the other end can be fixed to an external wall-hanging bracket.

In another aspect of the present invention, the bearing member has an L-shaped cross section.
In the present embodiment configured as described above, the bending in parallel with the longitudinal direction is performed at one place, and the necessary strength is generated.
In another aspect of the present invention, the bearing member has a U-shaped cross section.
In the present embodiment configured as described above, the required strength is generated by making the bending parallel to the longitudinal direction into two places.

  According to the present invention configured as described above, the external wall mounting bracket is fixed to the thin display panel via the bearing member and the PCB plate, so that compared with the case where a bridge-shaped connecting member is used as in the prior art. Thus, the configuration can be simplified. Further, when a member for connecting the connecting members is required, it is located on the back side of the main board. However, when straddling the main board, it is necessary to ensure a safety clearance. As a result, the casing had to be unnecessarily thick for the clearance. However, since such a member is not required, the problem of clearance can be eliminated.

According to the second aspect of the present invention, even when the main board interferes with the bearing member depending on the size of the main board, the main board can be accommodated and held while using the coaxial receiving member.
Further, according to the invention of claim 3, it can be formed of a general material by forming a substantially cylindrical shape.
Moreover, according to the invention of Claim 4, it can fix firmly, simplifying a manufacturing process by the fitting fixation by crimping.

According to the invention of claim 5, since the metal plate material is bent, it can be formed at a light weight and at a lower cost than in the case of a cylinder or a prism.
Moreover, according to the invention of claim 6, it can be set as a simple structure.
According to the invention of claim 7, the strength required for compactness can be obtained.
