Description

FLAT PANEL DISPLAY MODULE AND DISPLAY UNIT HAVING SUCH A FLAT PANEL DISPLAY MODULE}

The present invention relates to a flat panel display module and a display unit having the same, and more particularly, to a structure for receiving and fixing a flat panel display module in a shell structure of the display unit.

As display devices for various electronic devices, flat panel display modules are widely used at present.

As a flat panel display module, what is currently put to practical use is a liquid crystal display module, an electroluminescence (EL) display, a field emission display (FED), a light emitting diode (LED) display module, a plasma display panel (PDP), etc.

Flat panel display modules are typically housed in shell structures of display units of electronic devices.

The following proposals have been made to accommodate and fix the flat panel display module in the shell structure of the display unit.

That is, what is shown in FIG. 20 is the installation structure of the liquid crystal display module proposed by Unexamined-Japanese-Patent No. 9-160670.

Here, the liquid crystal display module 200 has the installation member 201 in four corners.

The screw 202 is inserted into the mounting member 201 in a direction perpendicular to the display surface of the liquid crystal display module 200, and the screw 202 is screwed into the front shell 203 of the display unit. Thus, the liquid crystal display module 200 is fixed.

In this structure, the mounting member 201 protrudes outward from the display surface of the liquid crystal display module 200, and therefore, a portion called a frame outside the display window 204 of the front shell 203 is provided. The width had to be secured more than a certain amount.

In this case, it is not possible to meet the request to make the width of the frame portion as narrow as possible and to increase the area ratio of the display surface of the liquid crystal display module to the area of the display unit as large as possible.

Thus, another flat panel display module mounting structure as shown in sectional view in FIG. 19 has been proposed.

This also exemplifies a liquid crystal display module as a flat panel display module, but this can be said to be a side mounting structure, and forms a mounting screw hole 101 in the side surface of the liquid crystal display module 100, Connect to the body of the device.

The metal member 102 integrally fixed to the member constituting the hinge portion extends to the side of the liquid crystal display module 100.

The screw 103 is screwed into the screw hole 101 in parallel with the display surface of the liquid crystal display module 100 through the metal member 102, thereby connecting the liquid crystal display module 100 and the metal member 102 to each other. By doing so, the liquid crystal display module 100 is assembled into the display unit.

According to this structure, the support member is provided on the side surface of the liquid crystal display module as compared with the method of inserting a screw perpendicular to the display surface of the liquid crystal display module so that the mounting member is protruded to the side of the liquid crystal display module. The thickness of the structure is reduced, and the width of the frame portion of the display unit can be narrowed by that amount.

However, in this system, there is a restriction that the size of the metal member 102 should be about the same as the side shape of the liquid crystal display module 100, and it is difficult to provide the metal member 102 having sufficient strength.

Therefore, there has been a problem that the display unit is weak against forces such as torsion, vibration, shock, etc. applied to the display unit from the outside.

In particular, in recent years, thinning and widening of liquid crystal display modules have been progressed, and accordingly, distortions are easily applied to the display screen.

Such torsion was difficult to be suppressed by the member 102 subject to the shape restriction which should be equivalent to the side surface of the liquid crystal display module, or a similar installation member.

Moreover, also in the assembling workability when the liquid crystal display module is assembled into the display unit, this method is not a good method.

An object of the present invention is to provide a novel installation structure that solves the problems of the installation structure of the display unit of the flat panel display module as described above.

One of the objects of the present invention is to provide an installation structure suitable for narrowing the frame portion of the display unit.

Another object of the present invention is to increase the installation strength of the flat panel display module in response to reduction in the thickness and light area of the display unit.

Another object of the present invention is to improve the assembly workability when the flat panel display module is assembled into the display unit.

(Actual example)

EMBODIMENT OF THE INVENTION Hereinafter, embodiment of this invention is described.

18 is a perspective view of a compact electronic device including the display unit 1 of the present invention.

As the electronic device, a laptop-type PC or a mobile PC may be recalled.

This electronic device is rotatably connected to the display unit 1 via the hinge portion 3 to one end of the main body 2 including an input device such as a keyboard.

The display unit 1 accommodates a flat panel display module in the shell structure 4.

In this embodiment, the liquid crystal display module 5 is selected as the flat panel display module.

The shell structure 4 is constituted by a pair of shells, namely the front shell 4a and the rear shell 4b, in which the display window 6 for exposing the display surface of the liquid crystal display module 5 is exposed. ) Is installed.

Next, the internal structure of the display unit 1 is first described with reference to FIGS. 1 and 2.

1 is sectional drawing cut along arrow A-A of FIG. 18, and FIG. 2 is sectional drawing similar to FIG. 1, but shows the state in the middle of assembly.

The front shell 4a and the rear shell 4b are resin molded articles, respectively, and by combining them, the shell structure 4 which has predetermined storage space inside is comprised.

The metal mounting plate 7 of the form which covers the inner bottom face and the inner side surface is fixed to the rear shell 4b.

The mounting plate 7 also functions as a shield for absorbing electron noise.

In the bottom surfaces of the rear shell 4b and the mounting plate 7, holes 9 and 10 for inserting the mounting screws 8 are formed in the four corners.

The liquid crystal display module 5 has the liquid crystal panel 11 which is a flat display panel, and the base frame 12 made of resin which positions and supports this liquid crystal panel 11.

13 is a metal front frame sandwiching the liquid crystal panel 11 between the base frame 12 and a bending member (not shown) integrally formed on the front frame 13 is attached to the base frame 12. By locking and holding, the liquid crystal panel 11 is held between the base frame 12.

The liquid crystal panel 11 is of a transmissive type whose back is illuminated by a backlight, and the base frame 12 has a stepped structure for holding the backlight 14 on the back of the liquid crystal panel 11. It is installed.

The backlight 14 is a so-called edge light type in which a light source not shown is disposed on one side of the light guide plate 15 having a shape equivalent to that of the liquid crystal panel 11.

The reflective sheet 16 is bonded to the lower surface of the light guide plate 15.

Further, on the upper surface of the light guide plate 15, a plurality of optical sheets 17 such as a prism sheet are stacked and arranged.

However, if the liquid crystal panel 11 is a reflective one, the backlight 14 does not necessarily need to be installed.

The insertion metal member 18 is disposed on the back surface of the base frame 12, that is, on the surface opposite to the display surface of the liquid crystal panel 11.

The inserting metal member 18 is insert molded at the time of forming the base frame 12 and has a hole 19 extending in a direction perpendicular to the display surface of the liquid crystal panel 11.

The hole 19 is a female screw hole which is screwed with the screw 8 and is exposed on the rear surface of the base frame 12.

The holes 19 are arranged at four corners of the base frame 12 corresponding to the holes 9 of the rear shell 4b.

The hole 19 can be arrange | positioned in the place other than the corner of the base frame 12, for example by arrange | positioning the insertion metal member 18 in the middle of the four sides of the base frame 12. As shown in FIG.

The base frame 12 is thickened toward the outside, and the insertion metal member 18 is inserted in this thick portion.

The hole 19 is disposed at a position overlapping with the liquid crystal panel 11 in a plane.

Here, "the liquid crystal panel 11 and the hole 19 overlap planarly" means that part or all of the projection of the hole 19 overlaps with the projection of the liquid crystal panel 11.

Since the screwing of the hole 19 and the screw 8 is performed on the back surface of the base frame 12, even if the liquid crystal panel 11 overlaps the hole 19, the liquid crystal panel 11 is screwed. It does not interfere with screwing in (8).

Thus, the position where the screw 8 which fixes the liquid crystal display module 5 in the perpendicular direction to the display surface, and the hole 19 which receives this screw 8 overlap with the liquid crystal panel 11 in plan view. Since the liquid crystal display module 5 is disposed at the side of the liquid crystal display module 5, the length of the portion other than the display surface extending outward can be shortened, which can contribute to narrowing of the so-called frame portion of the display unit 1.

That is, compared with the prior art of FIG. 20, narrowing of the frame portion can be realized.

Further, as compared with the prior art of Fig. 19, the frame portion can be narrowed by a portion corresponding to the thickness of the metal member 102 in the figure.

On the back surface of the base frame 12, a circuit board 20 electrically connected to the liquid crystal panel 11 is disposed through a flexible circuit board (not shown) or the like, and is made of metal so as to cover the circuit board 20. Rear plate 21 is disposed.

The back plate 21 is preferably sized to cover at least the entire circuit board 20 so as to absorb the noise generated in the circuit board 20.

The back plate 21 is mechanically and electrically connected to the front frame 13 through a connecting metal member (not shown) and is electrically connected to the ground potential pattern of the circuit board 20 directly or through circuit wiring. It is.

Therefore, the front frame 13 and the back plate 21 are maintained at the ground potential of the internal circuit of the liquid crystal display module 5, and function as a shield material for removing noise.

In addition, when the back plate 21 overlaps with the insertion metal member 18 planarly, the hole 22 is formed in the position corresponding to the hole 19 of the back plate 21. As shown in FIG.

The display unit 1 of Fig. 1 is assembled as follows.

First, the liquid crystal display module 5 assembled previously is overlapped with the rear shell 4b, and the position of the hole 19, 22, 10, 9 is aligned.

And the screw 8 from the outer surface side of the rear shell 4b, the hole 9 of the rear shell 4b, the hole 10 of the mounting plate 7, and the hole 22 of the back plate 21 Screw through the hole 19 of the insertion metal member 18 through.

As a result, the liquid crystal display module 5 is fixed to the rear shell 4b.

At this time, the mounting plate 7 is pressed into contact with the back plate 21 of the liquid crystal display module 5 so that the mounting plate 7 is interposed between the three plates of the mounting plate 7, the back plate 21, and the front frame 13. Connection is formed, and the mounting plate 7 is also maintained at the ground potential of the liquid crystal display module 5 in the same way as the rear plate 21 and the front frame 13, and functions as a shield material for removing noise. will be.

The periphery of the hole 9 of the rear shell 4b is thicker than another part, and the recessed part which accommodates the head of the screw 8 is formed in the outer surface of this thick part.

In addition, when the liquid crystal display module 5 does not include the back plate 21, the end of the front frame 13 is configured to be the outermost end of the liquid crystal display module 5, and the front frame 13 By making the tip contact the mounting plate 7, the electrical connection can also be achieved.

In this case, the front frame 13 and the mounting plate 7 are electrically connected to the ground potential pattern of the circuit board 20 by any suitable means other than the back plate 21.

Finally, the front shell 4a is superimposed on the rear shell 4b to fix the shells together, thereby completing the display unit 1.

Moreover, in order to raise the intensity | strength of the hinge part 3, in the shell structure 4, it is preferable to put a hinge member in the position which comprises the hinge part 3.

Thus, the liquid crystal display module 5 is shell-structured by arranging the hole 19 in the back surface of the liquid crystal display module 5, and screwing the screw 8 from the outer side of the shell structure 4 to this hole. Since it is set as the structure fixed to (4), the liquid crystal display module 5 can be fixed reliably, aiming at narrowing of a frame part.

In particular, by directly fixing the liquid crystal display module 5, which is easily twisted by thinning and light area, to the rear shell 4b, the occurrence of the twist can be suppressed.

That is, the installation strength is higher than the prior art of FIG. 19 with respect to the force from the outside, equivalent to the prior art of FIG. 20, or without the display window 6 of the rear shell 4b.

In addition, the installation of the liquid crystal display module 5 to the shell structure 4 is performed by a screw perpendicular to the display surface which is well adopted in such a case, and the liquid crystal display module ( In terms of 5), the assembly workability can be improved from the prior art shown in FIG.

In the case where the front shell 4a and the rear shell 4b are formed of a metal material such as magnesium alloy, the mounting plate 7 serving as a noise shield can eliminate this.

In addition, the head of the screw 8 is exposed to the outer surface of the rear shell 4b, and this can be covered with an adhesive tape or a decorative plate to improve aesthetics.

Next, a second embodiment of the display unit 1 will be described with reference to FIGS. 3 and 4.

FIG. 3 is a cross-sectional view taken along arrow A-A of FIG. 18, and FIG. 4 is a cross-sectional view similar to FIG. 3, but showing a state during assembly.

The same code | symbol is attached | subjected to the component which has a function common to 1st Embodiment, the description is abbreviate | omitted, and a different part is demonstrated.

This second embodiment differs from the first embodiment in that the liquid crystal display module 5 is fixed to the shell structure 4.

That is, in the first embodiment, the liquid crystal display module 5 is fixed by being screwed on the outside of the rear shell 4b. In this second embodiment, the mounting disposed inside the shell structure 4 is performed. The configuration in which the liquid crystal display module 5 is screwed to the plate 7 is eliminated, thereby eliminating the need to provide the holes 9 in the rear shell 4b.

Therefore, in the first embodiment, the mounting plate 7 fixed before the installation operation of the liquid crystal display module 5 on the inner surface of the rear shell 4b is mounted on the rear shell after the installation of the liquid crystal display module 5. 4b).

The mounting plate 7 may be configured to be completely detachable from the rear shell 4b, or may be configured to be rotatably connected to the shell structure 4 with the hinge 3 as the center.

In addition, one end of the mounting plate 7 may be fixed to a hinge member (not shown) constituting the hinge portion 3 so that the mounting plate 7 may be used as a hinge metal member.

The liquid crystal display module 5 is positioned and disposed on the mounting plate 7, and the hole of the insertion metal member 18 is formed through the hole 10 of the mounting plate 7 and the hole 22 of the back plate 21. By screwing the screw 8 into the 19, the liquid crystal display module 5 is fixed to the mounting plate 7. As shown in FIG.

Thereafter, the mounting plate 7 is fixed to the rear shell 4b using fixing means (not shown) such as screw fixing or a locking structure.

Thereafter, the display unit 1 is completed by providing the front shell 4a to the rear shell 4b.

Fixing to the shell structure 4 of the mounting plate 7 on which the liquid crystal display module 5 is fixed may be performed simultaneously with the connection of the front shell 4a and the rear shell 4b.

As described above, in the second embodiment, since the liquid crystal display module 5 is fixed to the mounting plate 7 disposed inside the shell structure 4, the screw 8 is attached to the display unit 1. The aesthetic appearance can be improved without exposing to the outer surface of the skin and damaging the aesthetic appearance.

In addition, in the shape of the mounting plate 7, since the restriction to be equal to the side shape of the liquid crystal display module 5 is not excessive, the shape having sufficient strength can be obtained, and the display unit can be thinned and the light area is increased. Can respond to demands of anger.

Moreover, since the installation of the liquid crystal display module 5 is performed by the screw which is perpendicular | vertical to a display surface similarly to 1st Embodiment, this also can raise assembly workability compared with the prior art of FIG.

In the above description, the screw 8 is screwed into the insertion metal member 18 inserted into the base frame 12 of the liquid crystal display module 5, but the screwing position of the screw 8 is shown. You can also configure

When the base frame 12 is formed of high strength resin or a material other than resin, the insertion metal member 18 can be abolished and the hole 19 can be directly provided in the base frame 12.

The hole 19 provided in the base frame 12 may have a screw groove as a screw hole, or one without a screw groove.

In the case where the screw groove is not drilled, a self-tapping screw is used as the screw 8, and the screw groove is formed simultaneously with the screw engagement.

The back plate 21 can also be used as a substitute for the inserting metal member 18.

That is, by carrying out burring process to the hole 22 of the back plate 21, a cylindrical part is integrally formed and a screw is engaged with this burring process hole.

It is good to put a screw groove in this burring hole previously, and it is also good to make a screw groove simultaneously with screwing by the self-tapping type screw.

As described above, in preparing a coupling point of a screw in the liquid crystal display module 5, a hole is provided in a component inserted into the base frame 12, a hole is provided in the base frame 12 itself, Although three types of methods, such as providing holes in the metal back plate 21 of the base frame 12 by burring, were introduced, these methods can be used by selecting one type of method and using one display unit 1. It does not mean that it must be applied to.

In the single display unit 1, these three types of methods can be used in combination.

Next, a third embodiment of the display unit 1 will be described with reference to FIGS. 5 and 6.

FIG. 5 is a cross-sectional view taken along arrow A-A of FIG. 18, and FIG. 6 is a cross-sectional view similar to FIG. 5, but showing a state during assembly.

The same code | symbol is attached | subjected to the component which has a function common to 1st Embodiment, the description is abbreviate | omitted, and a different part is demonstrated.

This third embodiment is a modification of the second embodiment.

That is, in the second embodiment, the mounting plate 7 was shaped to cover the entire inner bottom of the rear shell 4b, but in the third embodiment, the cross section in which the central portion of the mounting plate 7 is omitted is L-shaped. The angled mounting plate (7a) of this was replaced.

The mounting plate 7a covers the edge portion of the side where the hole 19 of the liquid crystal display module 5 exists.

The mounting plate 7a may be a two-piece type supporting two sides located on opposite sides of the liquid crystal display module 5, or a frame supporting four sides of the liquid crystal display module 5. It may be of a form.

Like the mounting plate 7, the mounting plate 7a may be configured to be completely separated from the rear shell 4b, or may be rotated around the hinge structure 3 in the shell structure 4. It is good also as a structure connected freely.

In addition, one end of the mounting plate 7a is fixed to a hinge metal member (not shown) constituting the hinge portion 3, and the mounting plate 7a can be used as a hinge member.

In any case, it is possible to reduce the weight of the display unit 1 by making the mounting plate cut out in the middle, but it is necessary to reflect it in the design so that sufficient strength can be secured with only the remaining parts.

Next, a fourth embodiment of the display unit 1 will be described with reference to FIGS. 7 and 8.

FIG. 7 is a cross-sectional view taken along arrow A-A of FIG. 18, and FIG. 8 is a cross-sectional view similar to FIG. 7, but showing a state during assembly.

The same code | symbol is attached | subjected to the component which has a function common to 1st Embodiment, the description is abbreviate | omitted, and a different part is demonstrated.

This embodiment is characterized by fixing the liquid crystal display module 5 without using a method of screwing the rear shell 4b or the mounting plate 7.

That is, the protrusion 23 is formed in the position corresponding to the hole 19 of the liquid crystal display module 5 in the inner surface of the rear shell 4b.

The protrusion 23 has a conical shape in which the top is cut off, and enters the hole 19 of the base frame 12 through the hole 22 of the back plate 21.

The hole 19 is provided directly in the base frame 12 itself.

If the front shell 4a is covered by the rear shell 4b with the projections 23 inserted in the holes 19, the liquid crystal display module 5 is sandwiched between both shells, and the shells are fixed. The module 5 is fixed in such a way that the projection 23 prevents the movement in the direction parallel to the display surface.

The hole 19 and the protrusion 23 are in close contact with the front shell 4a securely covered by the rear shell 4b.

The projection 23 must be a diameter that can withstand the holding of the liquid crystal display module 5.

If necessary, projections for pushing the liquid crystal display module 5 toward the rear shell 4b are added to the inner surface of the front shell 4a.

The mounting plate which existed in the previous embodiment is abolished in this embodiment.

In this manner, the projection 23 of the rear shell 4b is inserted into the hole 19 on the rear surface of the liquid crystal display module 5, and the front shell 4a is covered thereon to cover the liquid crystal display module 5 between the two shells. Since the liquid crystal display module 5 is fixed to both shells at the same time, the liquid crystal display module 5 is more reliably retained in the front shell 4a and the rear shell 4b. Along with the effect of narrowing, high installation strength can be realized.

In addition, since the fixing of the shells and the fixing of the liquid crystal display module 5 are performed in one operation, the assembly workability is improved.

Next, a fifth embodiment of the display unit 1 will be described with reference to FIGS. 9 to 17.

FIG. 9 is a cross-sectional view taken along the arrow A-A of FIG. 18, and FIG. 10 is a cross-sectional view similar to FIG. 9, but showing a state during assembly.

The same code | symbol is attached | subjected to the component which has a function common to 1st Embodiment, the description is abbreviate | omitted, and a different part is demonstrated.

This embodiment has a feature in that the liquid crystal display module 5 is fixed to the front shell 4a using the holes 19 on its rear surface.

That is, here, L-shaped cross section is used and the two mounting plates 7b which are independent of any of the front shell 4a, the rear shell 4b, and the liquid crystal display module 5 are used.

On the inner side surface of the front shell 4a, the protrusion 24 as shown in FIG. 11 is formed in the position which opposes each other.

Here, as shown in FIG. 13, it is assumed that two projections and four systems are provided for one side.

The hook 25 which catches this protrusion 24 is attached to the mounting plate 7b.

As shown in FIG. 11, the hook 25 is obtained by punching the L-shaped groove 26 formed of the introduction portion 27 and the engaging portion 28 to the mounting plate 7b, and the projection 24 Two are installed in one mounting plate 7b according to the number.

The protrusion 24 plays a role of position regulation such that the liquid crystal display module 5 does not deviate in a direction parallel to the display surface as well as the hook 25.

In addition, on the inner side of the front shell 4a, two projections 29 are provided on one side of the side at right angles to the side on which the protrusions 24 are provided. It is not merely a function of position control of the liquid crystal display module 5.

Next, the procedure for fixing the liquid crystal display module 5 will be described with reference to FIGS. 13 to 17.

FIG. 13 is a view of the inner surface of the front shell 4a from above.

The liquid crystal display module 5 is sandwiched between the protrusions 24 and the protrusions 29 of the front shell 4a as shown in FIG. 14.

Next, as shown in FIG. 15, the mounting plate 7b is placed on the edge of the liquid crystal display module 5.

Then, the mounting plate 7b is slid in a direction parallel to the edge of the liquid crystal display module 5, and the inside of the front shell 4a is at the point where the inlet portion 27 of the groove 26 coincides with the protrusion 24. The mounting plate 7b is pushed into the gap formed between the side surface and the edge of the liquid crystal display module 5.

Then, if the sliding is continued as it is, the hook 25 is caught by the protrusion 24.

At this time, the holes 10 of the mounting plate 7b coincide with the holes 19 of the liquid crystal display module 5.

This is the state of FIG. 16.

In this way, when the screw 8 is coupled to the hole 19 as shown in FIG. 17, the liquid crystal display module 5 is fixed to the front shell 4a via the mounting plate 7b.

The hook 25 of the mounting plate 7b may be formed in the same manner as that of the protrusion 24 as shown in FIG. 12 so as to secure the fixing more securely.

As described above, the liquid crystal display module 5 is fixed to the front shell 4a by using the holes 19 and the mounting plate 7b on the back thereof, and with the effect of narrowing the frame portion, the front shell 4a ) High installation strength can be realized by its rigidity.

Moreover, since the screwing of the mounting plate 7b and the liquid crystal display module 5 is performed by the screw 8 perpendicular | vertical to the display surface of the liquid crystal display module 5, the assembly operation | work rather than the prior art of FIG. Sex is improved.
