5. Application examples

  FIG. 1 illustrates an appearance of a display device according to an embodiment of the present disclosure. The display device 1 is used as a thin television device, for example, and has a configuration in which a flat main body 2 for image display is supported by a stand 3. The display device 1 is used as a stationary type with the stand 3 attached to the main body 2 and placed on a horizontal surface such as a floor, a shelf, or a stand, but with the stand 3 removed from the main body 2. It can also be used as a wall-hanging type.

  FIG. 2 is an exploded view of the main body 2 shown in FIG. The main body 2 includes, for example, a front exterior member (bezel) 11, a front bracket 12, a display panel 13, an intermediate housing (middle chassis) 14, an optical sheet 15, and an illumination member 16 from the front side (viewer side). , The balancer substrate 17, the reflection sheet 18, and the rear exterior member (rear cover) 19 are provided in this order. The front exterior member 11 is a frame-shaped member that covers the front peripheral edge of the display panel 13, and a pair of speakers 20 are disposed below the front exterior member 11. The rear exterior member 19 is a resin component that covers the entire back surface of the display panel 13. The bottom outer surface and the side outer surface of the rear exterior member 19 constitute a body surface (outermost surface) of the main body 2. A power supply board 21 and a signal board 22 are mounted and a mounting bracket 23 is fixed to the lower outside of the rear exterior member 19. The mounting bracket 23 is for mounting a wall-mounted bracket, mounting a substrate, etc., and mounting the stand 3. The power supply board 21, the signal board 22 and the mounting bracket 23 are covered with a covering member 24.

  The rear exterior member 19 also serves as a rear housing (back chassis) that houses the display panel 13 or the reflection sheet 18. That is, in the present embodiment, a single-layer structure using only the rear exterior member 19 is used instead of a double structure of a rear casing (back chassis) made of metal and a rear exterior member (rear cover) made of resin, which has been conventionally employed. Have taken. As a result, the conventional rear housing (back chassis) made of metal can be eliminated, and the number of parts can be reduced. Therefore, the display device 1 can be reduced in weight, the manufacturing process can be simplified, and the cost can be reduced.

  The front metal fitting 12 is a metal part provided in the upper central portion and the lower central portion of the front peripheral edge of the display panel 13 in order to enhance the durability of fixing the wall hanging bracket and improve the safety when hanging on the wall. is there. Conventionally, a front case (top chassis) that is a frame-shaped metal part is provided instead of the front metal part 12, and the display panel 13, the intermediate case 14, and the optical sheet are provided on the rear case made of metal. 15, the illumination member 16 and the reflection sheet 18 are accommodated, and the front peripheral edge of the display panel 13 is covered with a frame-shaped front housing to constitute a panel module. The front metal fitting 12 is obtained by leaving a part of the front housing. However, in the present embodiment, as described above, the rear housing made of the conventional metal is abolished, and the front housing or the front metal fitting 12 may be omitted completely in the same manner as the rear housing. Is possible.

  The display panel 13 includes, for example, a liquid crystal cell 13A, a source substrate 13B, and a flexible substrate 13C such as a COF (Chip On Film) that connects them (not shown in FIG. 2). 18). The intermediate housing 14 is a frame-shaped resin component that holds the display panel 13 and the optical sheet 15. The optical sheet 15 is a resin plate such as a diffusion plate.

  The illumination member 16 is composed of, for example, a plurality (for example, four in FIG. 2) of U-shaped cold cathode tubes. Specifically, as shown in FIG. 3, the illumination member 16 includes a plurality of linear light emitting units 16 </ b> A (two in FIG. 3, for example) arranged in the same direction, and a plurality of first light emitting units. And a second light emitting unit 16B that connects 16A to each other.

  The balancer substrate 17 is provided inside the bottom surface of the rear exterior member 19 along the side of the rear exterior member 19. As shown in FIG. 3, for example, a plurality of connectors 17A are mounted on the balancer substrate 17, and the distal end portion of the first light emitting portion 16A of the illumination member 16 is connected to each connector 17A. The illumination member 16 is not limited to the U-shaped tube, and may be a straight tube.

  The reflecting sheet 18 shown in FIG. 2 is for reflecting the light from the illumination member 16 toward the display panel 13, and is provided on the bottom surface and four side surfaces inside the rear exterior member 19. The reflection sheet 18 is divided into a plurality of sheets (for example, 4 to 5 sheets), and a notch for passing a support member 30 described later, a through hole for passing the illumination member 16 and the like are appropriately provided. Further, in the present embodiment, since the balancer substrate 17 is provided inside the bottom surface of the rear exterior member 19, the reflection sheet 18 also has a role of hiding the balancer substrate 17.

  FIG. 4 shows a configuration of the rear exterior member 19 shown in FIG. 2 viewed from the inside. A support member 30 that supports the illumination member 16 is provided inside the bottom surface of the rear exterior member 19. Two support members 30 are provided for each illumination member 16. As shown in FIG. 5, for example, the support member 30 includes a fixing portion 31, two arm portions 32, a support portion 33, and a needle portion 34. The fixing portion 31 is attached to the inside of the bottom surface of the rear exterior member 19. The two arm portions 32 protrude from the fixed portion 31 to both sides. The support portion 33 is provided at the tip of the arm portion 32 so as to float from the rear exterior member 19. Thereby, in this display apparatus 1, it is possible to protect the illumination member 16 from an impact.

  The support portion 33 has, for example, an arc shape, and holds the illumination member 16 in a point contact state by three projections 33A, 33B, and 33C provided on the inner peripheral surface. The needle part 34 has a function as a spacer that keeps the distance between the rear exterior member 19 and the optical sheet 15.

  Such a support member 30 can be integrally formed with the rear exterior member 19, for example, or can be configured as a separate member from the rear exterior member 19. In the former case, since the support member 30 is made of white resin, the rear exterior member 19 is also made of white resin. In that case, as a constituent material of the rear exterior member 19 and the support member 30, in order to suppress yellowing due to ultraviolet rays, a white resin excellent in light resistance, for example, a PC resin (polycarbonate resin) and an ABS resin (acrylonitrile-butadiene-styrene) are used. What added the resin) is preferable. In the latter case, the support member 30 needs to be made of white resin, but the color of the rear exterior member 19 is not particularly limited.

  FIG. 6 shows a state in which the illumination member 16, the balancer substrate 17, and the reflection sheet 18 are arranged inside the rear exterior member 19 shown in FIG. FIG. 7 is an enlarged view of the vicinity of the second light emitting unit 16B of the illumination member 16 shown in FIG. The illumination member 16 is arranged on the reflection sheet 18 while being supported by the support member 30. It is preferable that a light shielding member 40 is provided in the second light emitting unit 16 </ b> B of the illumination member 16. As a result, it is possible to suppress uneven brightness in the screen.

Specifically, the light shielding member 40 is a black adhesive tape attached to a position around the second light emitting unit 16 </ b> B in the rear exterior member 19. As the black adhesive tape, it is possible to use a commercially available black PET (polyethylene terephthalate) adhesive tape or the like. The light shielding member 40 may be black, gray, or the like, and is not particularly limited as long as it is an achromatic color or a chromatic color other than white. Since the reflective sheet 18 is spread on the bottom surface and the four side surfaces of the rear exterior member 19 as described above, the black adhesive tape as the light shielding member 40 is attached to the reflective sheet 18 instead of the rear exterior member 19 itself. Needless to say, it is.

  The light shielding member 40 is attached to, for example, a position below the second light emitting unit 16 </ b> B in the rear exterior member 19, more preferably a position directly below. The outer end (left side in the width direction) of the light shielding member 40 is desirably aligned with the outer end of the second light emitting unit 16B. Moreover, it is preferable that the light shielding member 40 is provided over the whole longitudinal direction of the 2nd light emission part 16B. This is because if the light shielding member 40 does not exceed the vertical length of the second light emitting unit 16B (that is, the light shielding member 40 does not cover the first light emitting unit 16A), it is possible to make it difficult to generate luminance unevenness.

  Specifically, the width of the black adhesive tape that is the light shielding member 40 is, for example, 10 mm, and the length is, for example, 40 mm. The diameter of the illumination member 16 is, for example, 4 mm, and the interval (pitch) between the two first light emitting units 16A is, for example, 45 mm. The distance from the center of the illumination member 16 to the reflection sheet 18 is, for example, 6.5 mm.

The balancer substrate 17 is provided inside the bottom surface of the rear exterior member 19 along the side of the rear exterior member 19. The rear exterior member 19 has a projecting piece 19 </ b> A at a position between the plurality of connectors 17 </ b> A mounted on the balancer substrate 17. The protrusions 19A are intended to prevent the rear exterior member 19 from being locally heated due to heat generated from the connector 17A, and intersect the arrangement direction of the plurality of connectors 17A from the inner side surface of the rear exterior member 19. It protrudes in the direction of

  That is, when the protrusion 19A is not provided, the thermal airflow 19B generated in the connector 17A proceeds straight from the vicinity of the connector 17A as indicated by the dotted arrow in FIG. Therefore, in the rear exterior member 19, as shown in FIG. 10B, local high temperature portions 19 </ b> C are formed on the back surface of the connector 17 </ b> A and the upper side surface. In the present embodiment, by providing the projecting piece 19A on the inner side surface of the rear exterior member 19, as shown by the solid line arrow in FIG. The formation of the portion 19C can be suppressed.

  In addition, it is desirable that such a projecting piece 19 </ b> A is provided in a space range that does not block the reflection sheet 18 and does not contact the balancer substrate 17.

  Further, as shown in FIG. 8, the rear exterior member 19 has depressions (thin portions) 19D at positions below the plurality of connectors 17A inside the bottom surface. The recess 19D is provided to easily release heat generated in the connector 17A by forming an air layer under the connector 17A. The depth of the recess 19D is, for example, about 0.5 mm. The balancer substrate 17 is fixed to the rear exterior member 19 with a double-sided adhesive tape or the like, and there is a gap of about 0.8 mm between the balancer substrate 17 and the rear exterior member 19, for example. Therefore, by providing the recess 19D, it is possible to secure, for example, a total air layer of about 1.3 mm below the connector 17A and improve the heat dissipation performance.

  FIG. 11 shows a planar configuration of the main body 2 shown in FIG. 1 as viewed from the back side. A plurality of screw holes 19 </ b> E for fixing to the front exterior member 11 are provided in the peripheral portion of the rear exterior member 19. A covering member 24 is covered on the outside lower region of the rear exterior member 19. Inside the covering member 24, a power supply board 21, a signal board 22, and a wall bracket mounting bracket 23 (not shown in FIG. 11, all refer to FIG. 2) are provided. A screw hole 24 </ b> A for fixing the mounting bracket 23 is provided below the covering member 24.

  FIG. 12 shows a state in which the covering member 24, the power supply board 21, the signal board 22, and the mounting bracket 23 are removed from the rear outer side of the rear exterior member 19 shown in FIG. A pair of bosses 19 </ b> F and umbrella-shaped ribs 19 </ b> G are provided on the lower outside of the rear exterior member 19.

  The pair of bosses 19F are for fixing the lower part of the wall-mounted bracket (see FIG. 13). The covering member 24 has a through hole 24B at a position aligned with the pair of bosses 19F. The pair of bosses 19 </ b> F and the through holes 24 </ b> B constitute lower VESA (Video Electronics Standard Association) holes built in the main body 2.

  The umbrella-shaped rib 19G has a triangular shape extending from the middle upper position of the pair of bosses 19F to the lower left and lower right. By providing such umbrella-shaped ribs 19G, it is possible to prevent the pair of bosses 19F from being corroded and damaged by the oil adhering to the appearance surface (the bottom surface outside and the side surface outside) of the rear exterior member 19.

  A pair of connecting parts 51 are provided at the upper center outside the rear exterior member 19 shown in FIG. As shown in FIG. 13, the connecting part 51 connects the upper part outside the bottom surface of the rear exterior member 19 and the upper part of the wall hanging bracket 52 when the wall hanging bracket 52 is attached to the back surface of the main body 2. It is an attachment. Further, as shown in FIG. 13, a gap G caused by a step between the covering member 24 and the outer bottom surface of the rear exterior member 19 is formed between the upper outside of the bottom surface of the rear exterior member 19 and the upper portion of the wall hanging bracket 52. Although generated, the gap G is absorbed by the connecting component 51.

  FIG. 14 illustrates a cross-sectional configuration taken along line XIV-XIV in FIG. One end of the connection component 51 is fixed to an upper VESA hole 51B provided in the rear exterior member 19 and the front metal fitting 12 by a screw 51A. By fixing the connecting member 51 not only to the rear exterior member 19 made of resin but also to the front metal part 12 made of metal, it is possible to improve the durability of fixing the wall hanging bracket 52 and improve the safety when hanging on the wall. It becomes. The other end of the connecting part 51 is provided with a screw hole 51C to which the wall hanging bracket 52 is actually fixed.

The lower end of the mounting bracket 23 of the wall-mounted bracket shown in FIG. 2 is fixed to the covering member 24, the rear exterior member 19 and the front bracket 12 by screws 23A. By fixing the lower end of the mounting bracket 23 not only to the rear exterior member 19 and the covering member 24 made of resin but also to the front bracket 12 made of metal, the durability of fixing the wall hanging bracket 52 is improved, and safety when hanging on the wall Can be improved.

  FIG. 16 illustrates a cross-sectional configuration taken along line XVI-XVI in FIG. As described above, the power supply substrate 21 is mounted on the left side of the rear exterior member 19 on the lower side outside the bottom surface. The power supply substrate 21 is preferably disposed with the electronic component mounting surface 21 </ b> A facing the rear exterior member 19. As a result, it is possible to maximize the space and reduce the thickness of the main body 2 of the display device 1.

  FIG. 17A shows the overall configuration of the intermediate casing 14 shown in FIG. The intermediate housing 14 includes a frame-shaped main body 14A and an outward flange 14B that protrudes downward from the frame-shaped main body 14A as shown in an enlarged view in FIG. The frame-shaped main body 14 </ b> A is for mounting the liquid crystal cell 13 </ b> A of the display panel 13. As shown in FIG. 18, the flange 14B holds the source substrate 13B in a state of hanging from the liquid crystal cell 13A mounted on the frame-shaped main body 14A. More specifically, the collar portion 14B reduces the stress on the flexible substrate 13C by temporarily placing the source substrate 13B in the manufacturing process, and suppresses the breakage of the flexible substrate 13C in the manufacturing process. Is.

  The display device 1 can be manufactured as follows, for example.

  19 to 21 show the manufacturing method of the display device 1 in the order of steps. First, as shown in FIG. 19, the balancer substrate 17 on which the plurality of connectors 17 </ b> A are mounted is provided along the side of the rear exterior member 19 inside the bottom surface of the rear exterior member 19.

  Next, the reflection sheet 18 is spread on the bottom surface and the three side surfaces of the rear exterior member 19. Similarly, as shown in FIG. 19, a light shielding member 40 made of a black adhesive tape is attached to the reflective sheet 18 at a position below the second light emitting portion 16 </ b> B of the illumination member 16, preferably at a position directly below.

  Subsequently, similarly as shown in FIG. 19, the illumination member 16 is fitted and held in the support portion 33 of the support member 30, and the tip end portion of the first light emitting portion 16A of the illumination member 16 is connected to the connector 17A. The balancer substrate 17 is hidden by the reflection sheet 18.

  After that, as shown in FIG. 20B, the optical sheet 15 is placed on the needle portion 34 of the support member 30.

  On the other hand, as shown in FIG. 20A, the display panel 13 is inserted into the intermediate housing 14 using a fully automatic jig (not shown). At this time, since the intermediate casing 14 is provided with the downward and outward flange portions 14B, when the liquid crystal cell 13A is placed on the frame-shaped main body 14A, as shown in FIG. The portion 14B is held in a state of hanging from the liquid crystal cell 13A placed on the frame-shaped main body 14A (temporary placement state).

  Subsequently, as shown in FIG. 21, the intermediate casing 14 on which the display panel 13 is placed is inserted into the rear exterior member 19. As a result, the source substrate 13B is inserted into a predetermined accommodation position of the rear exterior member 19 in a temporarily placed state, and is received by a fitting portion (not shown) provided inside the rear exterior member 19.

  On the other hand, when the intermediate housing 14 does not have the collar portion 14B, the source substrate 13B and the flexible substrate 13C are hooked anywhere in the process until the display panel 13 is accommodated in the rear exterior member 19. It is in a state where it can move freely without being. Therefore, when the intermediate housing 14 is inserted into the rear exterior member 19, the source substrate 13 </ b> B gets on the upper end of the rear exterior member 19, and the source substrate 13 </ b> B is manually moved to the predetermined accommodation position of the rear exterior member 19. Need to plug. During this manual operation, the flexible substrate 13 may be subjected to stress such as bending and may be damaged. In the present embodiment, by temporarily placing the source substrate 13B on the flange portion 14B in the manufacturing process, stress on the flexible substrate 13C can be reduced, and damage to the flexible substrate 13C in the manufacturing process can be suppressed. It becomes possible.

  After that, the front metal fitting 12 is attached to the front peripheral edge of the display panel 13, and the front exterior member 11 provided with the speaker 20 is fixed. Further, the power supply board 21 and the signal board 22 are mounted below the back surface of the rear housing 28, and the mounting bracket 23 of the wall-mounted bracket is fixed. After that, the lower outer side of the bottom surface of the rear exterior member 19 is covered with the covering member 24.

  In this way, the main body 2 shown in FIG. 1 is formed. Finally, the display device 1 shown in FIG. 1 is completed by attaching the stand 3 to the back surface of the main body 2.

  In the display device 1, the light from the illumination member 16 is reflected directly or by the reflection sheet 18, is uniformly diffused by the optical sheet 15, and enters the liquid crystal cell 13 </ b> A of the display panel 13. The incident light passes through a polarizing plate (not shown) and is then modulated for each pixel based on a video voltage applied between a pair of substrates (not shown) of the liquid crystal cell 13A. )). The light transmitted through the liquid crystal layer passes through a color filter (not shown), and is extracted outside the polarizing plate (not shown) as color display light.

  Here, the support portion 33 that supports the illumination member 16 is provided in a state of floating from the rear exterior member 19 at the tip of the arm portion 32. Therefore, as shown in FIG. 22, when the impact S1 is applied to the position on the back side of the support portion 33 in the rear exterior member 19, the lighting member 16 supported by the support portion 33 may receive the impact S1. Is small. In addition, when an impact S <b> 2 is applied to a position on the back side of the fixing portion 31 in the rear exterior member 19, the impact S <b> 2 is reduced when the arm portion 32 is transmitted.

  Incidentally, as shown in FIG. 23A, a normal display device has a double structure of a rear housing (back chassis) 119A made of metal and a rear exterior member (rear cover) 119B made of resin. Therefore, the possibility that the illumination member 116 in the rear housing 119A is damaged by the impact S3 from the back surface is not so great. On the other hand, as shown in FIG. 23B, when the rear exterior member 19 also serves as a rear housing (back chassis) that houses the display panel 13 or the reflection sheet 18, the rear exterior member 19 The impact S4 is easily transmitted directly to the illumination member 16 via the rear exterior member 19 made of resin. In the present embodiment, the illumination member 16 is protected from the impacts S1 and S2 by providing the support portion 33 that supports the illumination member 16 in a state of being lifted from the rear exterior member 19 at the tip of the arm portion 32. Is. In FIG. 23 (A), the same reference numerals in the 100s are assigned to the components corresponding to FIG.

  Moreover, since the black adhesive tape is affixed as the light shielding member 40 at a position below the second light emitting portion 16B in the rear exterior member 19 and preferably at a position directly below, the light from the second light emitting portion 16B is shielded. It is absorbed by the black adhesive tape which is the member 40. Therefore, the light from the second light emitting unit 16B is blocked by the light blocking member 40, and the display panel 13 is illuminated with uniform brightness by the light from the first light emitting unit 16A.

  On the other hand, when the light shielding member 40 is not provided, the right side of the display panel 13 is illuminated only by the first light emitting unit 16A, while the left side of the first light emitting unit 16A and the second light emitting unit 16B. Since both are illuminated, the luminance is uneven on the left and right sides of the screen. In the present embodiment, since the light-shielding member 40 is provided in the second light emitting unit 16B, such a difference in brightness between the left and right sides of the screen is corrected or adjusted, and uneven brightness in the screen is reduced.

  Further, as shown in FIG. 8 and FIG. 9, since the projecting piece 19A is provided inside the side surface of the rear exterior member 19, as shown in FIG. 10 (A), it rises right above the connector 17A. The hot air flow 19B is deflected laterally by the projecting piece 19A. Therefore, formation of the local high temperature part 19C of the rear exterior member 19 shown in FIG. 10 (B) is suppressed.
