Description

  The present invention relates to a panel type display device in which a frame-shaped bezel is combined with a front surface portion of a display panel with its effective display area facing outward from a display opening.

  The panel type display device includes a display panel such as a liquid crystal panel, a plasma display panel, or an electroluminescence display panel, and realizes a large display screen by reducing the weight and size as compared with the cathode ray tube display device. A panel type display device generally includes a chassis or a built-in speaker mounted with a display panel or a circuit board in a housing composed of a front cabinet (bezel) and a back cabinet to form a main body, and the main body is supported by a stand or the like. .

  In the panel type display device, the bezel is formed in a frame shape with a display opening that faces the effective display area of the display panel to the outside with a synthetic resin material, and a holder member and a back cabinet for holding the display panel And the like are integrally formed. As the panel type display device increases in size, a frame-like bezel that is integrally formed with a synthetic resin material also increases in size, and deformation due to factors such as molding conditions and load handling increases. In the panel type display device, an appropriate positioning portion is integrally formed on the bezel so that an effective display area of the display panel is accurately exposed outward from the display opening (for example, (See Patent Document 1).

  In a panel type display device (for example, a liquid crystal television receiver) 100, as shown in FIG. 5, a display panel (liquid crystal panel) 101 is fixed to a structure such as a chassis or a stay (not shown) such as a steel plate or an aluminum plate. The outer peripheral portion is held by a holder member 102 formed in a frame shape by a metal plate. In the panel type display device 100, the bezel 103 is combined with the front surface portion of the display panel 101 via the holder member 102. In the panel type display device 100, a bezel 103 or a back cabinet (not shown) is formed using, for example, a polycarbonate (PC) resin, a polystyrene (PS) resin, an acrylonitrile butadiene styrene (ABS) resin, or a mixed resin thereof.

  The bezel 103 is formed in an overall frame shape having a display opening 106 having an opening size that covers the outer peripheral area 105 while facing the effective display area 104 of the display panel 101 outward. The bezel 103 is integrally formed with an edge flange portion 107 that is inclined inward at a portion along the opening edge of the display opening 106. In a state where the bezel 103 is combined with the front surface portion of the display panel 101, the front end edge 107A of the rim flange portion 107 is held at a predetermined interval a with respect to the display surface and extends over the entire circumference, thereby displaying the display. The effective display area 104 of the panel 101 is trimmed.

  On the inner surface of the bezel 103, a large number of abutting ribs 108 having a predetermined height with an appropriate interval are projected integrally, and a large number of mounting bosses 109 are projected integrally. The Each abutment rib 108 is formed at a position facing the outer peripheral area 105 in a state where the bezel 103 is combined with the display panel 101, and the distance between the leading edge 107 </ b> A of the edging flange portion 107 and the display surface by hitting the outer peripheral area 105. a is defined. Each mounting boss 109 is configured to fix the bezel 103 to the holder member 102 by screwing the mounting screw 110 into each mounting boss 109.

  Although not shown in detail, the holder member 102 is integrally formed with a front holding piece portion 112 that holds the front surface of the display panel 101 on the front side of the outer peripheral holding portion 111 that holds the outer peripheral portion of the display panel 101. The back holding piece is fixed to the base plate combined with the display panel 101 on the back side, and is formed in a U-shaped cross section formed integrally. The holder member 102 is provided with a mounting bracket piece 113 which is formed of a separate member which is integrally bent on the back side of the outer peripheral holding portion 111 or which is fixed at one end to constitute a bezel mounting portion. The holder member 102 is appropriately formed according to the unit configuration including the display panel 101.

  In the holder member 102, the front holding piece 112 is formed with a height smaller than the width of the outer peripheral area 105 of the display panel 101. The outer holding part 111 holds the outer peripheral part and the front holding piece 112. Holds the outer peripheral region 105 and is combined with the outer peripheral portion of the display panel 101. The mounting bracket piece 113 is provided with a plurality of mounting holes, and each mounting hole faces the mounting boss 109 on the bezel 103 side in a state where the bezel 103 is combined with the display panel 101. The holder member 102 combines the bezel 103 and the display panel 101 by mounting the mounting screw 110 into the mounting boss 109 through the mounting hole from the mounting bracket piece 113 side.

  In the panel type display device 100, the nonwoven fabric 114 is joined to the abutment rib 108 of the bezel 103, and the nonwoven fabric 114 is interposed between the front holding piece 112 of the holder member 102 and the display panel 101. A combination is made. In the panel type display device 100, the nonwoven fabric 114 exhibits a buffering action between the abutment rib 108 and the front holding piece 112 due to sound emission from the built-in speaker, thereby reducing the occurrence of chattering.

  In the panel type display device 100, the bezel 103 is combined with the display panel 101 at a distance a between the display surface and the leading edge 107A of the edge flange portion 107 by the abutment rib 108 as described above. . The panel-type display device 100 prevents the occurrence of defects such as whitening by preventing the load from the bezel 103 side on the display panel 101 by providing this interval a. The panel type display device 100 is set such that the distance a is substantially equal to the sum of the height difference between the abutment rib 108 and the mounting boss 109 and the thickness of the nonwoven fabric 114.

Utility Model Registration No. 3110997

  By the way, in the panel type display device 100, distortion and deformation generated in the entire synthetic resin bezel 103 increase as the size of the panel type display device 100 increases, and even though the abutting rib 108 and the mounting boss 109 are formed precisely. In some cases, the combination accuracy with the display panel 101 varies. In the panel type display device 100, as described above, the display panel 101 and the bezel 103 are combined by setting an interval a of 1 mm to 2 mm between the display surface and the leading edge 107A of the edging flange portion 107. It is extremely difficult to accurately maintain the distance a over the entire area.

  In the panel type display device 100, the interval a becomes non-uniform over the entire area, thereby causing a problem that the finished appearance is impaired. In the panel type display device 100, the holder member 102 that holds the display panel 101 via the interval a is externally provided at a location where the interval a becomes larger than the design value in a state where the display panel 101 and the bezel 103 are combined. The problem that it will be visually recognized from will arise. Further, in the panel type display device 100, when the distance a is smaller than the design value, the front edge 107A of the rim flange portion 107 hits the display surface to damage the display panel 101 or deteriorate display characteristics such as whitening. Cause it to occur.

  Therefore, the present invention provides a simple structure in which a uniform gap is formed over the entire area between the front surface of the display panel and the inner surface of the opening edge of the display opening of the bezel, and a buffer material for preventing voice chatter is provided. An object is to provide an unnecessary panel type display device.

  The panel type display device according to the present invention that achieves the above-described object is directed to a display panel that has an effective display area outside the display opening with respect to a bezel that is formed of a synthetic resin material and has a display opening. The bezel mounting portion provided on the holder member for holding the display panel is fixed to the bezel. The panel type display device has a mounting boss that is screwed into the inner surface of the bezel to fix the bezel mounting portion of the holder member, and is abutted against the front surface of the holder member, so that the opening edge of the display opening and the display panel Abutting ribs that form a predetermined gap are integrally formed between the two. In the panel type display device, the mounting boss formed on the bezel is formed at a height that constitutes a gap between the mounting boss and the opposing bezel mounting in a state where the butting rib is butted against the holder member.

  In a panel type display device, a combination of a bezel and a display panel is formed by screwing a mounting screw into a mounting boss portion through a bezel mounting portion so that an effective display area is exposed outward from a display opening through a holder member. Is done. In a panel type display device, a bezel formed in a frame shape from a synthetic resin material may be slightly distorted or deformed due to molding conditions, mold temperature, or the like. In the panel type display device, the bezel is partly centered on the part where the mounting boss portion is erected in the range of the gap formed between the mounting boss portion and the bezel mounting portion by screwing the mounting screw. While being bent and drawn toward the holder member, the abutment rib protruding at a predetermined height from the inner surface hits the holder member. Therefore, in the panel type display device, even if the bezel is distorted or deformed, the height of the abutting rib is defined over the entire area between the front surface of the display panel and the inner surface of the opening edge of the display opening of the bezel. A uniform gap is formed.

  According to the panel type display device of the present invention, the mounting boss for screwing the mounting screw into the inner surface of the bezel and fixing it to the holder member, and the inner surface of the opening edge of the display opening by being abutted against the holder member A predetermined gap between the mounting boss portion and the bezel mounting portion provided on the holder member in a butted state so that a predetermined gap is maintained between the display panel and the display panel. Integrally formed. According to the panel type display device, when the mounting screw is screwed in, the bezel is partially pulled toward the holder member side, and the abutting rib protruding at a predetermined height from the inner surface hits the holder member, Even if the bezel has the distortion or deformation, the inner surface of the opening edge of the display opening and the front surface of the display panel are held in a constant gap over the entire area. Therefore, according to the panel type display device, it is possible to simplify the molding conditions and the handling of the load so as not to cause the bezel to be distorted or deformed, and the finish is good and the load is not applied to the display panel. It is possible to obtain a good appearance. According to the panel type display device, since the bezel and the holder member are firmly combined over the entire region, it is possible to eliminate a shock-absorbing material that prevents chatter due to sound emission, and the cost can be reduced.

  In the holder member 12, a plurality of bezel mounting portions 17 are integrally bent at appropriate intervals on the back side of each side of the holding frame portion 15. The bezel mounting portion 17 is a portion that is fixed to be opposed to the mounting portion provided on the bezel 6 side in a state in which the liquid crystal panel unit is combined with the bezel 6 as will be described later. A hole 18 is provided. The bezel mounting portion 17 is illustrated as a rectangular piece bent at a substantially right angle from the back side of the holding frame portion 15, but it is needless to say that the shape is not limited thereto. The bezel attachment portion 17 may be a portion where mechanical strength is achieved by, for example, an L-shaped cross section having a side surface portion or a channel shape.

  The holder member 12 has been described as a member in which the front holding piece 16, the back holding piece, or the bezel mounting portion 17 is integrally bent on the frame-like holding frame portion 15, but is not limited to this configuration. Of course. As for the holder member 12, for example, another member having the same function as the back surface holding piece portion or the bezel attaching portion 17 may be attached directly or via an interposed member. The holder member 12 can be a member equivalent to various holder members used in various conventional panel type display devices.

  When the above-described bezel mounting portion 17 is configured by a member different from the holder member 12, the liquid crystal television 1 does not need to use the same shape mounting member at all locations. In the liquid crystal television 1, the mounting member provided on the bottom side where the weight load is large is formed so as to have a large mechanical rigidity using a metal plate having a large thickness, and is provided on the side portion or the ceiling portion side where the weight load is relatively small.

An edge flange 21 that is integrally formed with an inward inclination along the opening edge of the portion 19, and an integrally formed along the outer peripheral edge of the front frame portion 20. It consists of a substantially channel frame-shaped member composed of a part of the outer peripheral flange portion 22. Although not shown in the figure, the bezel 6 is improved in mechanical strength by forming ribs on the inner surface of the front frame portion 20 in the form of a lattice, so that the back cabinet 7, the chassis plate 4 or the base plate of the liquid crystal panel unit is provided. A mounting boss part, a positioning convex part, and the like for positioning and combining are appropriately formed integrally. The bezel 6 is integrally formed with a mounting boss portion and a positioning convex portion for positioning and combining the built-in speaker unit 5 and the display portion substrate on the inner surface of the front frame portion 20. Further, the bezel 6 is formed with an attachment portion for positioning and combining with the stand 10 on the bottom surface of the front frame portion 20.

  A large number of mounting bosses 23 and abutment ribs 24 are integrally formed on the inner surface of the front frame 20 on the bezel 6 so as to position and combine the liquid crystal panel 2 via the holder member 12 as will be described later. Is done. Similarly to the conventional panel type display device 100, the bezel 6 also has a fringe flange in a state where the effective display area 14 is faced outward from the display opening 19 and is combined with the front portion of the liquid crystal panel 2 by the structure described later. The leading edge 21 </ b> A of the part 21 is held at a predetermined interval a with respect to the display surface and extends over the entire circumference, thereby bordering the effective display area 14.

  As shown in FIG. 3, mounting bosses 23 are integrally projected on the bezel 6 at positions corresponding to the mounting holes 18 formed in the bezel mounting portions 17 on the holder member 12 side. As shown in the figure, each mounting boss 23 includes two first mounting holes 18-1 and 18-2 arranged side by side in the length direction on each bezel mounting portion 17 on the holder member 12 side. When formed, it consists of a first mounting boss portion 23-1 and a second mounting boss portion 23-2 formed facing these mounting holes. Each of the mounting boss portions 23 is a cylindrical convex portion having a diameter larger than the hole diameter of the mounting hole 18, and the front end portion becomes a receiving surface of the bezel mounting portion 17 in a state where the bezel 6 and the liquid crystal panel 2 are combined. . Each mounting boss 23 is formed with a shaft hole 25 having an opening at the tip and the same diameter as the mounting hole 18.

  The mounting boss portion 23 includes a first mounting boss portion 23-1 and a second mounting boss portion 23-2 having different axial lengths. As shown in FIG. 3, the mounting boss portion 23 is in front of the first mounting boss portion 23-1 facing the first mounting hole 18-1 near the front frame portion 20 on the holder member 12 side. A second mounting boss portion 23-2 facing the second mounting hole 18-2 away from the frame portion 20 is formed on the long axis.

  The mounting boss 23 is fixed to the bezel mounting portion 17 by screwing mounting screws 26 into the shaft holes 25 from the mounting holes 18 facing each other. As the mounting screw 26, for example, a self-tapping screw that enters the inner wall of the shaft hole 25 while being threaded by a screwing operation is used, but other mounting screws may be used. The mounting screw 26 is also combined with a washer for screwing operation.

  Note that the bezel 6 may be provided by insert-molding a metal nut on the mounting boss portion 23 as necessary, for example, in a large-sized portion where a heavy load is partially applied. . Further, the bezel mounting portion 17 of the bezel 6 and the holder member 12 has not only a fixing structure by the mounting boss portion 23 and the mounting hole 18, but also a positioning structure including a positioning convex portion and a positioning hole that are relatively engaged, for example. You may make it provide.

  In the bezel 6, a plurality of abutment ribs 24 are integrally formed on the inner surface of the front frame portion 20 at appropriate intervals over the entire area. As shown in FIG. 3, each abutment rib 24, as shown in FIG. 3 in a state where the liquid crystal panel 2 is combined, abuts against the front surface holding piece 16 of the holder member 12. 21A is formed with a height that defines a predetermined distance a with respect to the display surface of the liquid crystal panel 2.

  Each abutment rib 24 projects in the vicinity of the bent portion of the holding frame portion 15 with respect to the front holding piece portion 16 of the holder member 12 as shown in FIG. 3 in a state where the bezel 6 and the liquid crystal panel 2 are combined. Hit. As will be described later, each abutment rib 24 presses the front holding piece 16 by being combined with the bezel 6 partially bent toward the holder member 12 side, but a bent portion having a large mechanical rigidity. The pressure contact force does not affect the characteristics of the liquid crystal panel 2 in combination with the plate thickness of the holder member 12.

  The abutment ribs 24 are all formed at the same height when the front frame portion 20 and the front holding piece portion 16 have the same interval over the entire circumference. Each abutment rib 24 has a height that defines the above-mentioned distance a in accordance with the abutment ribs of other parts, for example, for abutment ribs provided at different positions by providing an appropriate mounting portion or the like. Of course, it is formed by.

  In the bezel 6, each of the mounting bosses 23 described above holds the abutting rib 24 against the front holding piece 16 and holds the leading edge 21 </ b> A of the edge flange 21 and the display surface of the liquid crystal panel 2 at a distance a. In the state where it is combined with the liquid crystal panel 2, it is formed with an axial length constituting a distance b between the bezel mounting portion 17 and the opposite. As shown in FIG. 3, the interval b is configured with respect to the bezel mounting portion 17, and the first interval b-1 configured in the first mounting boss portion 23-1 is configured in the second mounting boss portion 23-2. Greater than the second interval b-2.

  In the bezel 6, as described above, the first mounting boss portion 23-1 and the second mounting boss portion 23-2 having different heights are formed. The difference in the distance b due to deformation or the abutting state of the abutting rib 24 is absorbed. Accordingly, in the bezel 6, the axial length of the first mounting boss portion 23-1 and the second mounting boss portion 23-2 is appropriately set, so that the pressure contact from the abutment rib 24 to the front holding piece portion 16 is achieved. The force may be adjusted.

  In the liquid crystal television 1, the liquid crystal panel unit is combined from the back side of the bezel 6 described above, so that the effective display area 14 of the liquid crystal panel 2 can be exposed to the side from the display opening 19, and the abutment rib 24 is a holder. Each mounting boss 23 is opposed to the opposing bezel mounting portion 17 of the holder member 12 by striking the front holding piece 16 of the member 12. In the liquid crystal television 1, if the bezel 6 is distorted or deformed due to molding conditions, mold temperature, handling, or the like, all the abutment ribs 24 against the front holding piece 16 of the holder member 12. The bezel 6 and the liquid crystal panel unit are combined in a state where they are not in contact with each other evenly.

  In the liquid crystal television 1, the mounting member 26 is screwed into the shaft hole 25 of the mounting boss portion 23 from the mounting hole 18 of each bezel mounting portion 17, thereby fixing the holder member 12 to the bezel 6. In the liquid crystal television 1, the bezel 6 and the holder member 12 form the mounting boss portion 23 with an axial length constituting the space b with respect to the bezel mounting portion 17 as described above. It is in a state where it is not kept constant over the entire area due to distortion or deformation. In the liquid crystal television 1, as shown in FIG. 4, the holder member 12 is fixed to the bezel 6 by screwing the mounting screws 26 until the tip ends of the mounting boss portions 23 abut against the bezel mounting portions 17. In the liquid crystal television 1, in this case, the screwing operation of the mounting screw 26 is performed from the second mounting boss portion 23-2 side where the interval b is small.

  In the liquid crystal television 1, by performing the above-described screwing operation of the mounting screw 26, a portion having a large interval b due to distortion or deformation in the bezel 6 or the abutting rib 24 hits the front holding piece 16 of the holder member 12. Even in a portion that is not in contact, the mounting boss 23 is drawn toward the front surface holding piece 16 and the tip end abuts against the bezel mounting portion 17. In the liquid crystal television 1, as shown in FIG. 4, the bezel 6 is distorted or deformed by the portions 20A and 20B in which the mounting boss portions 23 are formed on the inner surface of the front frame portion 20 being partially bent inward. The distance b or the difference in the abutting state of the abutting rib 24 is absorbed and the holder member 12 is combined.

  Therefore, in the liquid crystal television 1, each abutment rib 24 is abutted against the front holding piece 16 over the entire area even if the pressing force exerted on the front holding piece 16 is different, and is held by the bezel 6. The member 12 is fixed. In the liquid crystal television 1, the front edge 21 </ b> A of the rim flange 21 and the display surface of the liquid crystal panel 2 are thereby held at a distance a defined by the abutment rib 24 over the entire area, and the liquid crystal panel with respect to the bezel 6. 2 are combined. In the liquid crystal television 1, simplification of molding conditions and load handling to prevent the bezel 6 from being distorted or deformed is achieved, the finish is good, and the liquid crystal panel 2 is good without being loaded. A finished appearance can be obtained.

  Further, in the liquid crystal television 1, the front frame portion 20 is partially bent inward by the screwing operation of the mounting screw 26 described above, so that the tip end portion of each mounting boss portion 23 abuts against the bezel mounting portion 17. When the attachment is performed in this state, the holder member 12 is firmly fixed to the bezel 6 over the entire area. In the liquid crystal television 1, such a configuration eliminates the need for a shock-absorbing material that is joined to each abutment rib 24 to prevent chatter due to sound emission and a joining process thereof, thereby reducing costs.

  The present invention is not limited to the liquid crystal television 1 shown as the above-described embodiment, but can be applied to various panel type display monitor devices. A plasma display panel or an electroluminescence display panel is used as the display panel. It is also applied to various panel type display devices provided.
