Japanese Utility Model Publication No. 7-26870

The above-described method for forming a back cover for a display device has the following problems. That is, the back cover has a very large molding area, and an expensive metal mold is required for the integral molding, resulting in a problem that the manufacturing cost of parts increases. In addition, the manufacturing method by integral molding requires a die corresponding to each size even when the sizes are different, so that the component manufacturing cost is similarly increased. Therefore, the present invention reduces the manufacturing cost of the back cover. An object of the present invention is to provide a display device and a housing for a display device that can be manufactured at low cost.

  In order to solve the above problems and achieve the object, the display device casing and the display device of the present invention are configured as follows.

(1) A frame member that supports a display device, an electric board that is attached to the opposite side of the frame device to the display device and controls the display device, and a back cover that covers the frame member from the electric board side The back cover is formed by combining a plurality of members.

(2) The display device casing described in (1) above, wherein a protrusion is formed on the member.

(3) The display device casing according to (1), wherein the back cover includes the member and a cover member in which a hole for heat dissipation is provided in the vertical direction. It is characterized by that.

(4) The display device casing described in any one of (1) to (3), wherein the member is a metal member.

(5) a display device, a frame member that supports the display device, an electric board that is attached to the opposite side of the display device to the display device and controls the display device, and the frame member is attached from the electric board side. The back cover is formed by combining a plurality of members.

  According to the present invention, it is possible to reduce the manufacturing cost of the back cover and to reduce the manufacturing cost of the housing.

  FIG. 1 is a perspective view of the display device 10 according to the first embodiment of the present invention, with the main part cut away, and FIG. 2 is an exploded perspective view of the display device 10.

  The display device 10 is attached to the display panel 20, a front bezel 21 provided on the front surface of the display panel 20, a frame 22 provided on the rear surface of the display panel 20, and controls the display panel 20. An electric board 23 on which the control device is mounted and a back cover 30 that covers the electric board 23 are provided. Note that plates (cover members) 24 and 24 having a large number of ventilation holes are attached to the top and bottom of the back cover 30. The frame 22, the electric substrate 23, and the back cover 30 constitute a display device casing.

  As shown in FIG. 3, the back cover 30 is formed by combining a plurality of substantially flat panel members (metal members) 31 made of aluminum. The panel member 31 is formed by, for example, extrusion molding.

  The panel member 31 has a pair of flat plate portions 32, 33. The flat plate portions 32, 33 are arranged in a stepped manner so that the opposed surfaces 32 a, 33 a are partially exposed. A protrusion (projection) 34 is formed.

  A plurality of panel members 31 formed in this way are used, and as shown in FIG. 4, one surface 32a and the other surface 33a of adjacent panel members 31 are brought into contact with each other, and rivets, caulking, etc. Join with. Then, the back cover 30 is formed by combining necessary numbers. Thus, the back cover 30 can be formed without using a mold.

  5 and 6 are perspective views showing a plate-like panel member 35 according to a modification of the panel member 31. FIG. The panel member 35 has a so-called snap-fit structure having a convex portion 36 and a concave portion 37 at both ends, respectively, and a ridge portion 38 is formed on one surface side.

  A plurality of panel members 35 formed in this way are used, and as shown in FIG. 6, one projection 36 and the other recess 37 of adjacent panel members 35 are fitted and joined. Then, the back cover 30 is formed by combining necessary numbers.

  As described above, according to the display device 10 in which the display device casing according to the present embodiment is incorporated, the manufacturing cost of the back cover 30 can be reduced, and the combined parts of the panel members 31 and 35 are combined. It is possible to easily cope with the size change by adjusting the number. Further, the protrusions 34 and 38 provided on the panel members 31 and 35 can improve the heat radiation efficiency by limiting the flow paths that guide the heat inside and outside the display device casing upward.

  FIG. 7 is an exploded perspective view showing the display device 40 in which the display device housing according to the second embodiment of the present invention is incorporated. 7, the same functional parts as those in FIG. 2 are denoted by the same reference numerals, and detailed description thereof is omitted.

  In the present embodiment, the heat conductive sheet 41 is adhered to the convex surface of the protrusion 34. With the heat conductive sheet 41, the display device 40 according to the present embodiment can achieve the same effects as the display device 10 according to the first embodiment described above, and can further improve the heat dissipation. .

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the components without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the embodiment. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined.
