Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a liquid crystal display device in which a conductive sheet is interposed between a liquid crystal panel and a housing accommodating the liquid crystal panel, and an electronic apparatus including the same, and more particularly, to a stable liquid crystal panel and a conductive sheet. The present invention relates to a liquid crystal display device and an electronic device which can secure a stable shield effect by ensuring contact.
[0002]
[Prior art]
In recent years, as a casing material of a liquid crystal display device, a resin material that is lightweight and has excellent moldability into a complicated shape has been used. Since a housing itself cannot function as a shield body with a resin material having no conductivity, a separate shield mechanism is conventionally provided.
[0003]
For example, conductive coating is applied to the surface of the housing, or a conductive sheet such as an aluminum sheet is interposed between the housing and the liquid crystal panel. Alternatively, Patent Literature 1 discloses a housing of an electronic device having a DLC (Diamond Like Carbon) film formed on a surface and having excellent shielding properties.
[0004]
[Patent Document 1]
JP-A-11-346081
[Problems to be solved by the invention]
In the method of conducting coating or coating the DLC film, the coating or the DLC film is hard to turn around the base of protrusions such as bosses protruding from the inner surface of the housing for screwing the liquid crystal panel, etc. Variation is likely to occur. In addition, the conductive coating has a problem in that the cost of the coating jig and the coating is expensive and the cost is high. DLC coating is also costly.
[0006]
In the case of a conductive sheet, a part of the conductive sheet is fastened together with the liquid crystal panel to a boss for screwing the liquid crystal panel in order to make electrical contact with the liquid crystal panel side. However, this structure has a problem in that the contact state changes depending on the degree of screw tightening, and a stable shielding property cannot be obtained.
[0007]
SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and an object of the present invention is to provide a liquid crystal display device capable of performing stable electrical contact between a liquid crystal panel and a conductive sheet, and an electronic apparatus including the same.
[0008]
[Means for Solving the Problems]
In order to solve the above problems, the liquid crystal display device of the present invention is mounted on a side surface of a liquid crystal panel, and an end extending from the side surface is fixed to a housing, on a rear surface side of the liquid crystal display panel. A protruding portion is provided, and a cantilevered leaf spring portion is formed on a conductive sheet laid on the inner surface of the housing and interposed between the housing and the liquid crystal panel, and the leaf spring portion is attached. It is characterized by being elastically connected to the overhang of the tool.
[0009]
Further, in solving the above problems, the electronic device of the present invention is provided with a fixture which is attached to the side surface of the liquid crystal panel and whose end extending from the side surface is fixed to the housing, the back side of the liquid crystal display panel. A cantilevered leaf spring portion is formed on a conductive sheet laid on the inner surface of the housing and interposed between the housing and the liquid crystal panel. The liquid crystal display device having a configuration in which the liquid crystal display device is elastically contacted with the projecting portion of the attachment is rotatably attached to the main body.
[0010]
In the conductive sheet, the portion where the overhanging portion of the fixture comes into contact is a leaf spring portion, so when the overhanging portion of the attachment is brought into contact with the overhanging portion so that the leaf spring portion is elastically deformed, the leaf spring portion is brought into contact with the overhanging portion. A restoring force can be applied. As a result, stable contact between the overhang portion and the leaf spring portion is ensured, and noise generated from the liquid crystal panel or picked up by the liquid crystal panel can be conducted through the mounting fixture, the overhang portion, and the leaf spring portion. You can escape to the seat.
[0011]
The conductive sheet is fixed to the housing by, for example, caulking welding, and the mounting fixture has an end extending from the side surface of the liquid crystal panel, for example, is screwed to the housing. It is possible to maintain a stable elastic contact state between the two without causing a positional shift between them.
[0012]
Examples of the material of the conductive sheet include aluminum, copper, alloys thereof, stainless steel, and other metals and alloys. Alternatively, a non-conductive sheet surface may be coated with a conductive material such as a metal, an alloy, or a carbon-based material by a plating method, a sputtering method, an evaporation method, or the like.
[0013]
Further, if the leaf spring portion is composed of a plurality of small pieces which are divided from each other and can be elastically deformed independently from each other, even when the overhang portion contacts only a part of the leaf spring portion, the overhang portion can be formed. Any one of the small pieces of the leaf spring portion can be reliably elastically contacted to secure stable contact.
[0014]
If the tip of the leaf spring is bent toward the inner surface of the housing, the tip of the leaf spring abuts against the inner surface of the housing, so that the leaf spring is elastically deformed more than necessary (falling down). Can be prevented, and poor contact with the overhang portion can be avoided.
[0015]
In addition, the conductive sheet can function as a heat sink. That is, an inverter circuit board for driving the light source of the liquid crystal panel is disposed on the conductive sheet with a heat conductive member interposed therebetween, or a portion of the liquid crystal panel where the light source is built is electrically connected with the heat conductive member interposed therebetween. If it is arranged on the conductive sheet, the heat generated from the inverter circuit board or the light source built-in portion can be released to the conductive sheet via the heat conductive member.
[0016]
The heat conduction member has a function of removing air between the inverter circuit board or the liquid crystal panel and the conductive sheet, which hinders heat conduction, as well as having high heat conductivity. For example, a sheet-like material having elasticity and being able to adhere to both can be used. In addition, if it has elasticity, a buffering action for protecting the inverter circuit board or the liquid crystal panel from external impact can be obtained. For example, acrylic rubber, silicon rubber and the like can be mentioned.
[0017]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
[0018]
[First Embodiment]
FIG. 1 shows a plan view of a housing 52 on which the conductive sheet 3 according to the present embodiment is laid. The housing 52 is made of a resin material and has a flat box shape. A plurality of ribs 9 for reinforcing mechanical strength are formed on the inner surface of the housing 52, and the conductive sheet 3 is laid thereon. Hereinafter, the conductive sheet 3 will be described.
[0019]
(Configuration of conductive sheet)
The conductive sheet 3 is made of, for example, an aluminum material, and a plurality of (for example, four) leaf spring portions 7a to 7d and an inverter circuit board arrangement portion 15 are integrated with the main plate portion 4 occupying most of the conductive sheet 3. Connected.
[0020]
The leaf spring portions 7a to 7d are formed at four corners of the main plate portion 4, of which the leaf spring portions 7a and 7b are opposed to the inner wall surface of the housing 52 on the left side in the drawing, and the leaf spring portions 7c and 7d are shown in the drawing. It faces the inner wall surface of the housing 52 on the right side when viewed.
[0021]
Next, the details of the leaf spring portion 7a will be described with reference to FIG. 4. However, since the other leaf spring portions 7b to 7d have the same configuration as the leaf spring portion 7a, detailed description thereof will be omitted.
[0022]
The leaf spring portion 7 a has, for example, four small pieces 8 protruding toward the side inner wall surface of the housing 52, and the base of each small piece 8 is connected to the main plate portion via the connecting portion 13 raised from the main plate portion 4. 4 and is cantilevered with respect to the main plate portion 4. In a natural state, each small piece 8 has a substantially horizontal posture floating from the inner surface of the housing 52.
[0023]
Each of the small pieces 8 is separated from each other except for the base portion, and can be elastically deformed individually and independently. Specifically, when an overhang portion of a mounting tool, which will be described later, comes into contact with the tip end side of each small piece 8 and rides on it, the lower portion (of the housing 52) is supported by the root portion connected to the main plate portion 4 as a fulcrum. It is possible to individually and independently fall down on the (inner side), and at that time, an elastic restoring force acts to return to the original horizontal posture. The tip of each small piece 8 is bent toward the inner surface of the lower housing 52.
[0024]
In each of the leaf spring portions 7a to 7d, the number of the small pieces 8 is four, and the shape of each small piece 8 is rectangular. However, it is only necessary that each small piece 8 can be elastically deformed independently and independently. Never. Alternatively, the small pieces 8 may be provided with irregularities so as to undulate, and the projecting portions may be elastically contacted with the projecting portions of the mounting fixture described later. Further, the extending direction of the slit for dividing each small piece 8 is also the horizontal direction (the direction in which the tip end of the small piece 8 faces the inner wall surface of the side of the housing 52), but is formed along the vertical direction so that each small piece 8 is formed. Each of the leaf springs 7a to 7d may be supported on the upper edge side or the lower edge side and extend along the vertical direction.
[0025]
Referring again to FIG. 1, a rectangular inverter circuit board arrangement portion 15 is connected via a connection portion 16 to a substantially center of the lower edge portion of the main plate portion 4. The connection portion 16 is inclined downward from the main plate portion 4 toward the inner surface of the housing 52, and the inverter circuit board arrangement portion 15 is substantially horizontal. Therefore, the inverter circuit board arrangement portion 15 is located at a position lower than the main plate portion 4 on the inner surface side of the housing 52.
[0026]
Further, the conductive sheet 3 is formed with a plurality of drawn portions 10 that are recessed on the side facing the inner surface of the housing 52 and protruded toward the front side to improve the strength. Thereby, the conductive sheet 3 can be made thinner, and the weight of the entire liquid crystal display device can be reduced.
[0027]
Further, in the main plate portion 4, a recessed groove 12 for routing the antenna wire for wireless communication in the housing is formed in a portion near the leaf spring portions 7 a and 7 b so as to extend in the vertical direction.
[0028]
The conductive sheet 3 configured as described above is fixed to the housing 52 by caulking and welding. Specifically, caulking pins 11 are protruded at a plurality of locations on the inner surface of the housing 52, and the caulking pins 11 pass through the through holes formed in the conductive sheet 3 as shown in FIG. Then, the tip of the caulking pin 11 protruding from the through hole is welded and caulked.
[0029]
Thus, the conductive sheet 3 functions as a reinforcing plate that supplements the mechanical strength of the housing 52. As a result, the thickness of the housing 52 can be reduced, and the thickness of the liquid crystal display device can be reduced. In addition, caulking welding can reduce the gap between the inner surface of the housing 52 and the conductive sheet 3 as compared with screwing, which also contributes to a reduction in the thickness of the liquid crystal display device.
[0030]
Also, when transporting the components, the conductive sheet 3 is not handled alone, but is handled together with the housing 52 in a state where the conductive sheet 3 is attached to the inner surface of the housing 52. Can be prevented from being deformed.
[0031]
As shown in FIG. 2, an inverter circuit board 25 on which components such as a transformer 26 are mounted and a light source of a liquid crystal panel is driven includes an adhesive member 27a disposed on the inverter circuit board placement section 15 and an inverter circuit board placement section. The adhesive member 27b is adhered and fixed to the adhesive member 27b disposed on the side of the reference numeral 15.
[0032]
The inverter circuit board 25 is connected via a wiring cable and a connector to electrodes of a light source such as a cathode fluorescent lamp incorporated in a liquid crystal panel housed in the housing 52 via a fixture described later.
[0033]
3 are attached to the left and right side surfaces of the liquid crystal panel 2 indicated by alternate long and short dash lines, respectively, and the liquid crystal panel 2 is accommodated in a housing 52 together with the attachments 20a and 20b. The attachments 20a and 20b are made of, for example, a stainless material, and have strength for supporting the liquid crystal panel 2 in the housing 52 and conductivity as a conductive path for releasing noise to the conductive sheet 3. Other than stainless steel, for example, an Al-Mg alloy may be used.
[0034]
As shown in FIG. 6, for example, four screw holes 34 are formed in the side plate portion 35 facing the side surface of the liquid crystal panel 2 in the fixture 20 b, and screws are passed through these screw holes 34 so that the side surface of the liquid crystal panel 2 is formed. By being fastened, the fixture 20b is fixed to the side surface of the liquid crystal panel 2. The same applies to the other attachment 20a.
[0035]
A substantially rectangular overhang 21 bent from the side plate 35 is integrally formed on each of the attachments 20a and 20b, and these overhangs 21 are formed on the rear surface of the liquid crystal panel 2 (the surface opposite to the display surface). ) Are attached to the side surfaces of the liquid crystal panel 2 so as to protrude and overlap the sides. For example, two overhangs 21 are formed for each of the attachments 20a, 20b, and the interval between these two overhangs 21 is the above-described interval between the leaf springs 7a, 7b or the leaf spring 7c, The distance is substantially the same as the distance between 7d.
[0036]
In each of the fixtures 20a and 20b, a through hole is formed at the upper end extending from the side surface of the liquid crystal panel 2 so as to match a screw hole 19 provided on the inner surface of the housing 52. The screw is fastened by fastening the screw. Similarly, a through hole is formed at the lower end extending from the side surface of the liquid crystal panel 2 so as to match the screw hole 18 provided on the inner surface of the housing 52, and a screw is fastened to the screw hole 18 through this through hole. It is screwed by.
[0037]
As described above, the liquid crystal panel 2 is fixed to the housing 52 by the attachments 20a and 20b, and is accommodated in the housing 52 with the conductive sheet 3 interposed between the liquid crystal panel 2 and the housing 52. In addition, the lower surface of each projecting portion 21 of each of the fixtures 20a and 20b is in contact with the upper surface on the tip end side of each of the leaf spring portions 7a to 7d of the conductive sheet 3. The conductive sheet 3, the projecting portions 21 of the attachments 20a and 20b, and the inverter circuit board 25 are all located on the back side of the liquid crystal panel 2, and the liquid crystal panel 2 is accommodated with its display surface facing up.
[0038]
(Shielding action by conductive sheet)
As shown in FIG. 5, when the projecting portion 21 of the fixture 20 a supporting the liquid crystal panel 2 (not shown in FIG. 5) comes into contact with the tip end side of each small piece 8 and gets on the top, With the root portion connected to the main plate portion 4 as a fulcrum, it falls down (the inner surface side of the housing 52), and at this time, an elastic restoring force to return to the original horizontal posture acts on the overhang portion 21. Then, the small piece 8 elastically contacts the overhang portion 21.
[0039]
As a result, stable contact between the overhang portion 21 and the leaf spring portions 7a to 7d is ensured, and noise generated in the liquid crystal panel 2 or picked up by the liquid crystal panel 2 from the outside is electrically conductive via the fixtures 20a and 20b. The seat 3 can be reliably released.
[0040]
In addition, in assembling, the projecting portion 21 and the leaf spring portions 7a to 7d are simply brought into contact with each other, and are superior in workability as compared with the conventional example in which conductive coating or screwing is used to connect to the liquid crystal panel. I have.
[0041]
Further, even in a situation in which the overhang portion 21 contacts only a part of the leaf spring portions 7a to 7d due to a displacement or the like, the small pieces 8 of the leaf spring portions 7a to 7d are separated from each other except for the base portions thereof. Since each of the small pieces 8 can be elastically deformed independently and independently, any one of the plurality of small pieces 8 can be reliably elastically contacted with the overhang portion 21, and the stable overhang portion 21 and the conductive sheet 3 Contact can be secured.
[0042]
Further, since the distal ends of the leaf spring portions 7a to 7d (each small piece 8) are bent toward the inner surface of the housing 52, the distal ends of the leaf spring portions 7a to 7d (each small piece 8) come into contact with the inner surface of the housing 52 so that the leaf spring portions 7a to 7d ( Unnecessary elastic deformation (falling) of each small piece 8) is prevented, and poor contact with the overhang portion 21 can be avoided.
[0043]
The above description can be applied to the other three projecting portions 21 other than those shown in FIG.
[0044]

The thickness of the heat conducting member 28 is made slightly thicker than the adhesive members 27a and 27b arranged on both left and right sides thereof. As a result, as shown in FIG. 8, the inverter circuit board 25 can be bonded and fixed to both adhesive members 27a and 27b in a state where the adhesive strength to the heat conductive member 28 is increased. Note that, among the components mounted on the inverter circuit board 25, the transformer 26 that generates a particularly large amount of heat is arranged on the heat conducting member 28.
[0046]
(Function of heat conduction member)
The heat generated from the inverter circuit board 25, particularly from the transformer 26, can be released to the conductive sheet 3 made of, for example, aluminum having excellent heat dissipation through the heat conductive member 28. Since the inverter circuit board 25 is in close contact with the heat conducting member 28, the heat from the inverter circuit board 25 is efficiently conducted without intervening air in the heat transfer path from the inverter circuit board 25 to the conductive sheet 3. Can be diffused to the conductive sheet 3. As a result, it is possible to prevent each component in the inverter circuit board 25 from malfunctioning or malfunctioning.
