Description

  The present invention relates to a video display device such as a flat panel display or a flat panel color television using, for example, a plasma display panel (PDP) or a liquid crystal panel, and more particularly, this kind of lack of strength due to the thinning of the video display device. In this way, an image display device that can be made ultra-thin is realized by using a reinforcing frame that is strengthened to supplement the reinforcement.

  Flat panel displays or flat panel color televisions that can be made thinner are becoming thinner due to recent technological improvements. For example, as an example of the thinning configuration of a flat liquid crystal panel, the outer periphery of the liquid crystal panel is held by a plurality of stays and fixed to the front panel, thereby enabling the flat panel color TV to be reduced in weight and thickness. Technology is disclosed. (For example, refer to Patent Document 1).

The technique of Patent Document 1 described above is that the front panel can be thinned because there is no need for a screw receiving structure that is long in the thickness direction for screwing the liquid crystal panel to the front panel.

  However, as measures to realize further thinning of the flat panel display, it is also necessary to improve the layout of the chassis portion on which the flat panel is mounted or to construct the front panel from a short frame assembly. However, there is a frame that also serves as a reinforcement that determines the strength of the entire display set. In order to further reduce the overall thickness of this set, the depth of the entire set is significantly reduced, so that there is not enough depth space. Therefore, the width of the channel shape of the frame is larger than the conventional specifications. There is a problem that a sufficient strength of the set main body cannot be obtained because it is narrow and has a low height.

  The present invention was made to solve the above-described problems, and by increasing the strength of the frame while keeping the depth of the entire set thin, the strength of the entire set is increased and the thickness is further reduced. An object of the present invention is to obtain a video display device that can realize the above.

  In order to solve the above-mentioned problems and achieve the object of the present invention, a video display device according to claim 1 according to the present invention is fixed to the front panel and a front panel comprising an assembly of a plurality of short frames. An image display device comprising a filter glass, a flat panel display disposed behind the filter glass, and a rear cover that integrally fixes the flat panel display together with the front panel, from the back of the flat panel display A frame is attached to reinforce the strength of the assembly structure including the flat panel display body, and the frame is attached to the channel-shaped main frame with a U-shaped cross section and the reverse channel shape with a U-shaped cross section. The reinforcing frame is assembled and fixed to form a square cross section.

  The video display device according to claim 2 is characterized in that the entire frame has a bridge shape.

  The video display apparatus according to claim 3 is characterized in that the reinforcing frame is intermittently assembled to the main frame.

  According to a fourth aspect of the present invention, the video display device is a flat panel display or a flat panel color television.

  According to the video display device of the first aspect of the present invention, even if the frame width size is narrow and the height is low, the cross-section is the same as the U-shaped channel-shaped main frame. By installing a U-shaped reverse channel reinforcement frame and forming a square cross-sectional shape, the strength of the frame can be improved and the strength of the assembled structure can be increased, making the video display device even thinner Can be realized.

  According to the video display device of the second aspect, since the entire frame is configured in a bridge shape, the rigidity can be increased from the shape of the frame.

  According to the video display device of the third aspect, since the reinforcing frame is intermittently assembled with the short frame with respect to the main frame, the frame strength can be sufficiently maintained and the weight of the frame can be reduced.

  According to the video display device of the fourth aspect, an ultra-thin flat panel display or a flat panel color television is obtained.

  Reference numeral 8 denotes a plate-like frame called a so-called bezel having an opening 8a having approximately the same size as the video display screen 1, and this frame 8 is formed by injection molding a glossy resin such as an acrylic resin. It is a thing. 9L and 9R are a left speaker mounting plate and a right speaker mounting plate, and both the left speaker mounting plate 9L and the right speaker mounting plate 9R are U-shaped symmetrically and are injection-molded with resin. . A speaker is attached to each of the left speaker attachment plate 9L and the right speaker attachment plate 9R.

  The left speaker mounting plate 9L and the right speaker mounting plate 9R are slid and engaged from the left side and the right side of the frame 8. In this example, a plurality of engaging holes 8b are integrally formed on the left end and the right end of the frame 8, respectively, and a plurality of engaging protrusions 9a are formed on the inner ends of the speaker mounting plates 9L and 9R, respectively. , 9R are slid onto the frame 8 so that the engaging projections 9a engage with the engaging holes 8b, and the speaker mounting plates 9L, 9R are assembled to the frame 8.

  10U and 10D are an upper transparent member and a lower transparent member, and the upper transparent member 10U and the lower transparent member 10D have a length of a predetermined width along the upper side and the lower side of the video display screen 1, and are transparent, for example. It is injection-molded with a simple acrylic resin. The upper transparent member 10U and the lower transparent member 10D are slid and engaged with the upper side and the lower side of the frame body 8, respectively. In this example, a plurality of engagement holes 8c are integrally formed on the upper side and the lower side of the frame body 8, respectively, and a plurality of engagement protrusions 10a are provided on the opposing ends of the upper transparent member 10U and the lower transparent member 10D with the frame body 8, respectively. Then, the upper transparent member 10U and the lower transparent member 10D are slid to the frame body 8 so that the engagement protrusion 10a engages with the engagement hole 8c, and the upper transparent member 10U and the lower transparent member 10D are engaged with the frame body 8. I try to assemble it.

The front panel 2 is assembled as follows.
First, the left speaker attachment plate 9L and the right speaker attachment plate 9R are attached to the left end and the right end of the frame 8, and the upper transparent member 10U and the lower transparent member 10D are attached to the upper and lower sides of the frame 8, respectively. Then, a filter glass 3 that is slightly larger than the video display screen 1 is disposed on the back surface of the frame body 8, and thereafter, an upper front frame 11a, a lower front frame 11b, a left front frame 11c, and a right front frame that are formed by processing iron plates. 11d and four corner brackets 12a, 12b, 12c and 12d processed with an iron plate are used, and the frame body 8, the left speaker mounting plate 9L and the right speaker mounting plate 9R, the upper transparent member 10U and the lower transparent using screws or the like. The member 10D and the filter glass 3 are fixed integrally as shown in FIG.

  The front panel 2 assembled as described above has a filter glass 3 so that the plasma display panel 4 is spaced from the filter glass 3 by a predetermined gap as shown in FIGS. A chassis 5 and a pair of left and right speakers 13 on which the plasma display panel 4 and its drive circuit are mounted are incorporated via a cushion material C attached to the outer periphery of the rear surface of the TV. Composed.

  As described above, according to this example, the front panel 2 has the five-piece structure including the frame body 8, the left and right speaker mounting plates 9L and 9R, and the upper and lower transparent members 10U and 10D. The mold can be made inexpensive without being enlarged, and the front panel 2 can be thinned to realize a novel design.

  Here, with the thinning of the set of the television main body, a frame 14 for reinforcing the strength of the set is provided. In this example, as shown in FIG. 8, the frame 14 is provided in parallel by passing in the vertical direction from the rear side of the chassis 5 on which the driving circuit of the plasma display panel 4 is mounted. In this example, two frames 13 are used, and the chassis 5 is arranged at a position obtained by dividing the horizontal length of the chassis 5 into approximately three equal parts. In addition, when the number of the frames 13 exceeds 40 inches, for example, it is a design matter to reinforce the set by appropriately increasing the number of frames 13.

  As shown in FIGS. 9 and 10, the frame 14 has a U-shaped channel shape in cross section, and a main frame 15 formed in a so-called bridge shape as a whole, and a reverse channel having a U-shaped cross section in the main frame 15. A plurality of short reinforcing frames 16 are intermittently fitted, and each of the reinforcing frames 16 is fixed to the main frame 15 with screws 17 so that the cross section has a square shape.

  Mounting plates 15 a and 15 b are provided at both ends of the main frame 15, and both the mounting plates 15 a and 15 b are fixed so as to be sandwiched between the front panel 2 and the rear cover 6. At this time, the frame 14 is assembled to the chassis 5 via a spacer 18a made of a cushion material as shown in FIG. Further, a spacer 18b made of a cushion material is interposed so that the rear cover 6 does not hit the frame 14.

  Note that a cylindrical portion 15c is formed on the lower end side of the main frame 15, and when the television main body set in the cylindrical portion 15c is supported on the stand 7, a projection (not shown) protruding from the stand 7 is inserted. To increase the assembly strength.

  Since the frame 14 is configured as described above, even if the width size of the frame 14 is narrow and the height is low, the strength of the frame is improved, whereby the strength of the entire set can be increased, and the plasma can be increased. The color television can be made thinner. For example, in a plasma color television of 42 inches or more, a conventional set depth dimension of about 10 cm can be reduced to 89 cm.

  In addition, since the main frame 15 has a bridge shape, it is possible to obtain rigidity without being deformed even with respect to stress in the vertical and horizontal directions of the set or stress in the torsional direction. Further, since the auxiliary frame 16 is obtained by intermittently assembling a short frame with respect to the main frame 15, the weight can be reduced and the entire set can also be reduced.

  The present invention is not limited to the embodiment described above and shown in the drawings, and various modifications can be made without departing from the scope of the invention.

  In the embodiment of the present invention, the plasma color television using the plasma display panel has been described as an example. However, the present invention can be widely applied to the case where the strength of a set of a flat panel display such as a liquid crystal panel is increased.

  Further, although the example in which the auxiliary frame 16 is screwed to the main frame 15 has been described, the auxiliary frame 16 may be fixed to the main frame 15 by rivets or spot welding.
