Description

  The present invention relates to a panel type display device having a large display screen in which a joint portion between a display panel body and a frame member is blinded by a blindfold frame portion that borders the outer peripheral portion of an image display region over the entire circumference.

  The panel type display device uses a display panel body such as a plasma display panel (PDP), a liquid crystal display panel, or an electro luminescent light source display panel, for example. Compared with the cathode ray tube (CRT), it realizes a large display screen, lighter weight and thinner. For example, a PDP display device realizes a large display screen of 50 inches or more and has features such as a good image quality and a lightweight and thin shape that can be used as a wall-mounted type. It is attracting attention as a receiver and a large display device (Patent Document 1).

  In general, the panel type display device is configured by combining a display panel body with a rectangular frame-shaped holder member called a bezel with its display surface facing outward from a rectangular opening. On the other hand, like the panel type display device 100 shown in FIGS. 4 and 5, the front panel 102 formed of a glass plate, a transparent polycarbonate resin, or the like is superimposed on the front surface of the display panel body 101 and these are displayed. There is also provided a panel type display device having a bezelless structure in which the assembly is housed in a frame member 103 formed in a substantially frame shape by a transparent resin material.

  In the panel type display device 100, the front panel 102 is overlaid on an outer peripheral flange portion 104 having an outer peripheral portion formed integrally with the opening of the frame member 103, and a channel-shaped outer peripheral holder member 105 is fitted on these outer peripheral portions. By being combined, the overlapping state is maintained. In the panel type display device 100, a mounting portion 106 is integrally formed on the inner peripheral surface of the frame member 103, and a metal panel holder member 107 and a back cover member 108 are set to the mounting portion 106. 109 is fixed with screws.

  In the panel type display device 100, since the level of electromagnetic waves radiated from the display panel body 101 is strong, it is possible to cope with electromagnetic shielding. In the panel type display device 100, an electromagnetic wave shielding layer 110 made of a copper fine wire mesh layer formed by, for example, a photo-etching process of copper foil is provided on the inner surface of the front panel 102. In the panel type display device 100, the electromagnetic wave shielding layer 110 and the back cover member 108 are electrically connected via the panel holder member 107, whereby the internal space is configured as the shield space portion 111. In the panel type display device 100, a first speaker box 112 and a second speaker box 113 are combined on both sides as shown in FIG.

  Although the details are omitted, the back cover member 108 has an overall rectangular box shape covering the periphery of the display panel body 101, and an attachment portion 114 formed integrally with the outer peripheral portion of the opening portion is used as the attachment portion 106 of the frame member 103. They are combined so as to overlap and fixed by a set screw 109. The back cover member 108 has a taper that gradually increases the opening diameter of the outer peripheral portion toward the opening, and is formed with a height sufficient to cover the display panel body 101.

  The panel holder member 107 includes a receiving piece portion 115 that is abutted against the inner surface of the front panel 102, a base portion 116 that is abutted against the distal end portion of the attachment portion 106 of the frame member 103, and an attachment piece that is superimposed on the bottom surface of the attachment portion 106. The part 117 is integrally formed and formed in a crank shape. The panel holder member 107 is combined with the mounting piece 117 so as to overlap the mounting section 106 and fixed by a set screw 109, whereby the outer peripheral portion of the front panel 102 is held by the receiving piece 115.

  In the panel type display device 100 configured as described above, the feeling of thinness is further emphasized by eliminating the outer peripheral frame shape of the bezel as compared with the conventional panel type display device. In the panel type display device 100, so-called floating display is performed in which a unique display in which an image floats in space is performed on a flat display surface. In the panel type display device 100, a large screen feeling can be obtained by giving a feeling of spreading to the outer periphery. In the panel type display device 100, the display area efficiency of the front part is improved.

  By the way, in the panel type display device 100, the frame member 103, the back cover member 108, and the panel holder member 107 described above are coupled at the outer periphery of the display panel body 101 as shown in FIG. . In the panel type display device 100, from such a structure, the coupling site, the outer peripheral portion of the display panel body 101, the substrate of the optical display unit (not shown), the wiring of the speaker boxes 112 and 113, and the like are visible from the front side.

  In the panel type display device 100, a blind frame part 118 that blinds the above-described parts appearing on the outer peripheral part of the display panel body 101 from the outside is formed on the inner surface of the front panel 102. The blindfold frame portion 118 is formed of a black opaque layer on the inner surface of the front panel 102, for example, with a black ceramic print from the position facing the outer peripheral portion of the effective display area of the display panel body 101 to the outer peripheral portion. In the panel type display device 100, each of the above-described outer peripheral portions of the display panel body 101 is covered with the blind frame portion 118, and the floating display effect is obtained by displaying the image so that the image is lifted up. It will be even higher.

  By the way, in the panel type display device 100, as described above, the frame member 103, the back cover member 108, and the panel holder member 107 are coupled together at the outer peripheral portion of the display panel body 101, and the coupling portion is blindfolded by the blindfold frame portion 118. To do. In the panel type display device 100, the blindfold frame 118 is, specifically, as shown in FIG. 5, the area A facing the outer part from the effective display area of the display panel body 101, and the front panel holder of the panel holder member 107. The region B facing the width of the portion 107 and the region C facing the mounting portion 106 of the frame member 103 are shielded.

  Therefore, in the panel type display device 100, as shown in FIG. 4, a relatively wide blind frame 118 is provided so as to surround the outer periphery of the effective display area of the display panel body 101. The panel type display device 100 has the feature of improving the floating display effect by the blindfold frame portion 118 as described above. However, there is a problem that the balance of the display surface is deteriorated by increasing the width. there were. Further, in the panel type display device 100, since the area ratio of the blind frame portion 118 is increased, there is a problem that the effective display area efficiency of the front portion cannot be obtained so much as compared with the conventional display device. It was.

  In the panel type display device 100, the blindfold frame portion 118 is formed by applying a relatively wide black ceramic print, but there is a problem that accurate printing is difficult because there is no variation in thickness. In the panel type display device 100, since the large front panel 102 and the frame member 103 are required, the member cost increases and the handling becomes troublesome.

  In the panel type display device 100, in particular, the frame member 103 has sufficient mechanical strength by constituting the structure of the entire device, and the occurrence of weld lines as an exterior member is reduced, resulting in a highly accurate finish.

For this purpose, the frame member 103 is molded by a special molding method using a molding machine capable of molding a large product with high performance and a molding die having a high accuracy and a complicated structure.

  Further, in the panel type display device 100, as described above, the back cover member 107 whose outer peripheral portion has a height sufficient to cover the display panel body 101 is formed by drawing. For this reason, the back cover member 107 has a problem that the processing cost is high, and it is difficult to perform processing such as providing a step or providing a bent portion as necessary, and the degree of freedom in shape is small.

  In the panel type display device 100, as described above, the electromagnetic wave shielding layer 110 provided on the inner surface of the front panel 102 and the back cover member 108 are electrically connected to each other through the panel holder member 107 so that the display panel body 101 is shielded. Must be housed in 111. Therefore, in the panel type display device 100, the panel holder member 107 is formed with relatively high accuracy so that the electromagnetic wave shielding layer 110 and the back cover member 108 are firmly connected. In the panel type display device 100, the long panel holder member 107 formed in a crank shape is likely to bend in the length direction, and the inner surface of the front panel 102 extends over the entire area with respect to the panel holder member 107. A process of adjusting to keep it in a stable state was also necessary.

  Accordingly, the present invention has been proposed for the purpose of providing a panel-type display device that follows the characteristics of the floating display structure and has a blindfold frame portion formed on the inner surface of the front panel that is reduced in width without impairing its characteristics.

Is formed. The blindfold frame portion 12 is formed on the back surface of the front panel 5 by, for example, black ceramic printing. Further, as shown in FIG. 1, the blindfold frame portion 12 constitutes a frame-shaped transparent region 13 having a predetermined width along the outer peripheral edge of the front panel 5. Therefore, in the panel type display device 1, an image is displayed in the area surrounded by the blind frame 12 of the front panel 5, and the display image is lifted by the surrounding frame-shaped transparent area 13. A display form is exhibited.

  In the panel type display device 1, for example, an optical display unit 14 that optically displays a power-on state and a setting state of a mounted function is provided in the left and right frame-like transparent regions 13 of the front panel 5, although details are omitted. It has been. Further, in the panel type display device 1, a light receiving portion is formed which is located in the blindfold frame portion 12 of the front panel 5 and receives an infrared ray of a control signal emitted from a remote controller (not shown).

  The frame member 6 is composed of an upper frame member 6A and a lower frame member 6B having a halved structure constituting an overall substantially rectangular tube in the combined state. The frame member 6 is formed of an upper frame member 6A and a lower frame member 6B that are substantially symmetrical in the vertical direction, and the above-described substantially rectangular tube body is configured by integrating the abutting end portions via a joint member (not shown).

  In the frame member 6, the display panel body 4 is housed in the exterior cylinder part 15 from the opening on the front side, and the display panel body 4 is fixed on a mounting portion (not shown) formed in the exterior cylinder part 15. In this state, the frame member 6 extends so that the attachment portion 17 wraps around the back side of the display panel body 4. Although not described in detail, the frame member 6 is appropriately formed with an attachment portion for positioning and assembling the back cover member 7, the outer periphery holder member 8, the panel holder member 9, or the bracket member 10.

  In the panel type display device 1, the frame member 6 is a housing for attaching and holding the function of the exterior member and the heavy display panel body 4 and the speaker boxes 2 and 3 having a large screen of 60 inches or more as described above. It is a member having a function and a function of superposing the front panel 5 to constitute a part of the front member or a light guide function of internally illuminating the optical display unit 14. The frame member 6 is formed of a transparent synthetic resin material as described above, but has a sufficient mechanical strength, a high-precision flatness that does not cause distortion and the like, and a weld line that is not noticeable. Is required.

  When the frame member 6 having such characteristics is integrally molded, a high-precision and large-sized molding machine and a precise and complicated molding die are used. However, the molding efficiency and the yield are poor and the cost becomes extremely high. At the same time, it is difficult to obtain sufficient molding accuracy. Therefore, as described above, the frame member 6 is formed by being divided into the upper frame member 6A and the lower frame member 6B, and these halves are integrally combined. By adopting such a structure, the frame member 6 achieves the above-mentioned predetermined functions and improves finishing accuracy and cost reduction.
