Description

  The present invention relates to a support structure for optical sheets and a display device including the support structure, and relates to a support structure for an optical sheet suitably applied to a liquid crystal display device and a display device including the support structure.

  Among flat display devices, for example, a transmissive liquid crystal display device has a light source disposed on the back side of a display panel (that is, a liquid crystal panel), and transmits light emitted from the light source so that an image is displayed on the display panel. Is displayed in a visible state. Between the light source and the display panel, there is a plate-like or sheet-like member such as a diffusion plate, a diffusion sheet, a lens sheet, or a polarizing reflection film in order to adjust the characteristics of light incident on the display panel from the light source. Arranged to be stacked. Hereinafter, these plate-like or sheet-like members disposed between the light source and the display panel are collectively referred to as “optical sheets”.

  Since the cold-cathode tube generally used as a light source of such a display device has mercury, it is necessary to remove the cold-cathode tube that is no longer needed from the display device and collect it. Also, when a failure occurs or when the life of the cold cathode tube is long, it may be necessary to disassemble the display device and replace the cold cathode tube. However, since the cold cathode tube of the light source is disposed on the back side of the display panel and the optical sheets, in order to remove the cold cathode tube, the display panel and the optical sheets must first be removed, In the configuration in which the optical sheets are removed one by one, it takes time to disassemble. For this reason, the structure which can remove optical sheets easily from a display apparatus is desired.

  FIG. 6 is an exploded perspective view schematically showing an assembly structure of a conventional display device having a structure in which the optical sheets can be easily detached. In the display device 101 shown in FIG. 6, a reflection sheet 103 is laid on a backlight angle 102 formed in a flat plate shape, and a cold cathode tube 104 is disposed thereon and held by a lamp holder 105. The lamp holder 105 is a substantially rod-like member formed of, for example, a synthetic resin material, and is attached along the short side of the backlight angle 102 to hold both ends of the cold cathode tube 104.

  The optical sheets 106 are collectively supported by the dedicated angle 110 and are arranged on the lamp holder 105 while being supported by the dedicated angle 110. The dedicated angle 110 includes a front-side member 110a and a back-side member 110b each formed into an open quadrilateral. The optical sheets 106 are collectively held between the front-side member 110a and the back-side member 110b, and the front-side member 110a and the back-side member 110b are coupled together by screws or the like so as to be optical. Sheets 106 are supported. A frame 107 formed in an open quadrilateral is disposed on the front surface of the dedicated angle 110, and the display panel 108 is disposed on the front surface of the frame 107. A bezel 109 formed in a quadrilateral opening from above is mounted and fixed.

  According to the structure shown in FIG. 6, the optical sheets 106 are collectively supported by the dedicated angle 110, and are arranged between the lamp holder 105 and the frame 107 in that state. For this reason, when disassembling the display device 101, the optical sheets 106 can be removed together by removing the dedicated angle 110.

  However, the configuration including the dedicated angle for holding the optical sheets has a problem that the number of parts of the display device increases, resulting in an increase in the weight of the display device and an increase in manufacturing cost.

  In view of the above circumstances, the problem to be solved by the present invention is to provide a support structure or display device for optical sheets that can be easily removed and replaced, or to support optical sheets without using a dedicated angle. It is an object to provide a support structure or a display device for optical sheets.

  In order to solve the above-described problems, the four sides of the optical sheet that is arranged between the light source and the display panel and adjusts the characteristics of light incident on the display panel from the light source are formed into an open quadrilateral to support the light source. By sandwiching the first frame body between the first frame body and the second frame body that is formed into an open quadrilateral and supports the display panel, the optical sheet is supported.

  The first frame includes four members each formed in a substantially L shape, and is formed into an open quadrilateral frame by arranging the ends of these members to face each other. . Moreover, it may be formed in an open quadrilateral frame by disposing a member formed in a substantially straight bar shape between the ends of the members formed in a substantially L shape. .

  In addition, a reflection surface that reflects light emitted from the light source and enters the display panel is formed on the inner peripheral surface of the first frame.

  Since the optical sheets are supported by being sandwiched between the first frame that supports the light source and the second frame that supports the display panel, a dedicated angle for supporting the optical sheets is not required. become. For this reason, the number of parts can be reduced, and the weight of the display device can be reduced and the manufacturing cost can be reduced.

  And when disassembling a display apparatus and removing a light source, optical sheets can be removed from a display apparatus with the state supported between the 1st frame and the 2nd frame. In other words, at least the optical sheet, the first frame body, and the second frame body can be integrally removed and thereby the light source can be accessed immediately. Therefore, it is not necessary to separate and remove the optical sheets one by one, and the cold cathode tube can be easily removed.

  In addition, since the optical sheets are sandwiched between the first frame body and the second frame body at the four sides, the deformation of the optical sheets is suppressed, and the first frame body and the second frame body. Can be prevented from falling out from between the frame.

  Here, the first frame is configured by combining four members formed in a substantially L shape, but at least diagonal members may have the same shape. it can. For this reason, what is necessary is just two types of this substantially L-shaped member, and the raise of the manufacturing cost of this 1st frame can be suppressed. In addition, since the first frame has a four-part structure, the size of each member can be reduced, and the manufacturing cost can be reduced.

  In addition, if the first frame is configured to combine a member formed in a substantially L shape and a member formed in a substantially straight bar shape disposed therebetween, the dimensions of each member can be reduced. An increase in manufacturing cost can be suppressed.

  And even if it is a case where each member which comprises the 1st frame by a temperature change changes a dimension, a dimension change can be absorbed in the joint of each member.

  Conventionally, the side where the lamp holder on the backlight angle does not exist reflects the light from the light source to be incident on the display panel by bending the reflection sheet, but it is reflected on the first frame. By providing the surface, there is no need to bend the reflection sheet.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a view showing an embodiment of a display device provided with a support structure for optical sheets according to the present invention. Specifically, an assembly of a liquid crystal display device provided with a support structure for optical sheets according to the present invention is shown. It is the disassembled perspective view which showed the structure typically. Hereinafter, the support structure for optical sheets according to the present invention and the display device according to the present invention may be referred to as “the present structure” and “the present display device”, respectively.

  First, an outline of the configuration of the display device having the present structure will be described with reference to FIG. The display device 1 includes a cold cathode tube 4 as a light source, a reflection sheet 3 that reflects light emitted from the cold cathode tube 4, an optical sheet 6 that adjusts the characteristics of the light emitted from the cold cathode tube 4, The display panel 8 displays the image in a visible state by transmitting the light that has passed through the optical sheets 6. The lamp holder 5 and the frame 7 are provided, the cold cathode tube 4 is supported by the lamp holder 5, the display panel 8 is supported by the frame 7, and the optical sheet 6 is interposed between the lamp holder 5 and the frame 7. It is sandwiched and supported. Furthermore, it comprises a backlight angle 2 formed in a flat plate shape and a bezel 9 formed in an open quadrilateral, and between the backlight angle 2 and the bezel 9, a reflective sheet 3, a cold cathode tube 4, The lamp holder 5, the optical sheets 6, the frame 7, and the display panel 8 are arranged.

  A method of assembling the display device 1 having such a configuration is as follows. In this specification, the side on which the bezel 9 is disposed (upper side in FIG. 1) is referred to as the front side of the display device 1, and the side on which the backlight angle 2 is disposed (lower side in FIG. 1). This is referred to as the back side of the display device 1.

  A reflection sheet 3 is laid on the front side of the backlight angle 2, and cold cathode tubes 4 are arranged side by side on the front side, and a lamp holder 5 is attached thereto. As a result, the cold cathode fluorescent lamp 4 is held on the backlight angle 2. Further, an optical sheet 6 is placed on the front side of the lamp holder 5, a frame 7 is attached thereto, a display panel 8 is placed on the front side of the frame 7, and a bezel 9 is further attached. Then, the bezel 9 and the frame 7, the bezel 9 and the lamp holder 5, and the frame 7 and the backlight angle 2 are coupled by screws or the like (not shown). Thereby, the display device 1 is assembled.

  Next, each member constituting the display device 1 will be described. As shown in FIG. 1, the backlight angle 2 is a member formed in a flat plate shape, and is formed, for example, by pressing from a metal plate material. The reflection sheet 3 is a flat sheet-like member having a high surface reflectance, and is formed of, for example, a synthetic resin material. Since the backlight angle 2 and the reflection sheet 3 and the cold cathode tube 4 used as the light source can be those commonly used in the related art, detailed description thereof is omitted.

  The lamp holder 5 includes a first member 51 and a second member 52 each formed in a substantially L shape, and an open quadrilateral by combining the first member 51 and the second member 52. Formed.

  FIG. 2 is an external perspective view schematically showing the structures of the first member 51 and the second member 52 that form the lamp holder 5, wherein (a) shows the first member 51, and (b) shows the first member 51 and (b). Shows the second member 52. FIG. 2C is a cross-sectional view taken along line AA of the first member 51 or the second member 52 shown in FIGS. 2A and 2B. As shown in FIG. 2, the first member 51 and the second member 52 are each formed in a substantially L shape, and a support surface 501 that supports the optical sheets 6 is formed on the front side. A reflection surface 503 having a predetermined inclination angle with respect to the support surface 501 is formed on the inner peripheral surface side of the support surface 501. Further, on the outer peripheral surface side of the support surface 501, a standing wall 502 is formed that protrudes in a partition shape toward the front surface side.

  Further, both the first member 51 and the second member 52 are configured such that the distal ends thereof can be connected to the distal ends of the other adjacent members 52 and 51. Specifically, as shown in FIG. 2, one end of each of the members 51 and 52 (the tip located on the left side in FIG. 2A and the tip located on the upper side in FIG. 2B) A stepped overlapping portion 504 that is one step lower than the support surface 501 and the reflecting surface 503 is formed, and an engaging arm 505 extends from the overlapping portion 504. As shown in FIG. 2C, the engagement piece 506 is provided at the other tip (the tip located on the right side in FIG. 2A and the tip located on the lower side in FIG. 2B). It is installed in a state of floating on the back side of the support surface 501.

  In addition, a screwing portion 591 and a bezel engagement piece 592 that protrude toward the front surface are formed in the vicinity of the outer peripheral edge of the support surface 501 of the first member 51 and the second member 52. The screwing portion 591 has a substantially cylindrical shape in which a screw hole is formed at the center.

  The first member 51 and the second member 52 are integrally formed of, for example, a synthetic resin material. At least each of the reflecting surfaces 503 is preferably a white color having a high light reflectance. Specifically, white polycarbonate resin or the like can be applied.

  In order to connect the first member 51 and the second member 52, the distal ends of the first member 51 and the second member 52 are brought into contact with each other, and the engaging arm 505 is supported on the supporting surface 501 of the other distal end. The overlapping portion 504 is overlapped with the supporting surface 501 and the reflecting surface 503 at the tip of the other end. Thereby, the open quadrilateral lamp holder 5 is formed. At this time, the first members and the second members are arranged diagonally.

  Since the engaging arm 505 is only inserted between the back surface of the counterpart support surface 501 and the engaging piece 506, the first member 51 and the second member 52 are connected. The engaging arm 505 can reciprocate so that it can be inserted and removed. And since the superimposition part 504 is superimposing on the back side of the support surface 501 climbing slope 503 of the other party member, a clearance gap does not arise between front-end | tip parts.

  FIG. 3 is an external perspective view of the lamp holder 5 and shows a state in which the first member 51 and the second member 52 are connected. As shown in FIG. 3, a support surface 501 is formed on the front side of the lamp holder 5 over four sides, and the support surface 501 is surrounded by a standing wall 502. The reflective surface 503 is configured to form an inclined surface having an opening area that increases from the back side toward the front side and reflect light toward the front side. Since the 1st member 51 and the 2nd member 52 can reciprocate removably in a connection part, each side of the lamp holder 5 becomes telescopic in a longitudinal direction (namely, direction of arrow a, respectively).

  FIG. 4 is an exploded perspective view schematically showing the structure of each member of the lamp holder 5, the frame 7, and the bezel 9 of the display device 1 and the assembly structure including the optical sheets 6 and the display panel 8. .

  Referring to FIG. 4, the frame 7 is formed by, for example, pressing a metal plate material, and has substantially the same configuration as that generally used conventionally. And it forms in the open quadrilateral, and the cross section is formed in the substantially L shape by which the outer peripheral side was bent up toward the back side. On the front side, a positioning piece 71 for positioning and placing the display panel 8 is bent and formed, and an engagement hole 74 for engaging a bezel engagement protrusion 592 of the lamp holder 5, An insertion hole 75 for inserting the screwing portion 519 is formed. In addition, a screw hole for connecting to the bezel 9 and a screw hole for connecting to the backlight angle 2 are formed, but they are omitted in the drawing.

  The bezel 9 is a member formed by, for example, pressing a metal plate material, and has substantially the same configuration as that generally used conventionally. The bezel 9 also has an open quadrilateral shape, and the cross section is formed in a substantially L shape with the outer peripheral surface side bent and raised toward the back surface side. Then, an insertion hole 92 for inserting the screwing portion 591 of the lamp holder 5 and an engagement hole 93 for engaging the engagement protrusion 592 are formed. In addition, an insertion hole 91 for passing a screw for coupling to the frame 7 and a screw hole for coupling the frame 7 and the backlight angle 2 are formed, but these are omitted in the drawing.

  The insertion holes 75 and 92 and the engagement holes 74 and 93 formed in the frame 7 and the bezel 9 have a long hole shape that is long along the longitudinal direction of the side. For this reason, the screwing part 519 and the engagement protrusion 516 of the lamp holder 5 can reciprocate in the insertion holes 75 and 92 and the engagement holes 74 and 93 along the longitudinal direction of each side.

  The display panel 8 includes a pair of substrates that sandwich the liquid crystal and a drive circuit substrate that controls the alignment state of the liquid crystal. Since the display panel 8 can be a conventional general liquid crystal display panel, detailed description thereof is omitted.

  Details of the assembly structure of the lamp holder 5, the optical sheets 6, the frame 7, the display panel 8, and the bezel 9 are as follows.

  As shown in FIG. 4, the optical sheet 6 is mounted on the support surface 501 of the lamp holder 5 at the four peripheral edges. Here, the notch 61 formed in the peripheral edge portion of the optical sheet 6 is positioned by engaging with the positioning piece 507 of the support surface 501 of the lamp holder 5.

  When the frame 7 is attached to the lamp holder 5 on which the optical sheets 6 are placed, the tip of the standing wall 502 of the lamp holder 5 and the back side of the frame 7 come into contact with no gap. For this reason, the optical sheets 6 are supported in such a manner that the peripheral edges of the four sides are sandwiched between the support surface 501 of the lamp holder 5 and the back side of the frame 7 and are surrounded by the standing wall 502.

  The display panel 8 is placed in a region surrounded by positioning pieces 71 formed on the front side of the frame 7, and the bezel 9 is mounted from the front side. Then, the engagement protrusion 592 of the lamp holder 5 engages with the engagement holes 74 and 93 formed in the bezel 9 and the frame 7. The screwing portion 591 passes through the insertion holes 75 and 92 and is exposed to the front side of the bezel 9. In this state, the bezel 9 and the frame 7, the bezel 9 and the lamp holder 5, and the frame 7 and the backlight angle 2 are coupled to each other.

  The bezel 9 and the frame 7 are assembled together by screwing. Thereby, the display panel 8 is sandwiched and supported between the bezel 9 and the frame 7. The frame 7 and the backlight angle 2 are also assembled together by screwing.

  The bezel 9 and the lamp holder 5 are coupled by fastening a screw to a screwing portion 519 of the lamp holder 5 that passes through the insertion holes 75 and 92 of the bezel 9 and the frame 7 and is exposed to the front surface of the bezel 9. As a result, the optical sheets 6 are supported while being sandwiched between the lamp holder 5 and the frame 7. As described above, the optical sheet 6 is supported by sandwiching the peripheral portions of the four sides between the support surface 501 of the lamp holder 5 and the frame 7. Therefore, the deformation of the optical sheets is suppressed, and it is possible to prevent the optical sheets from falling off due to the bending deformation.

  Thus, since a dedicated angle is not required to support the optical sheets as in the prior art, the weight of the display device can be reduced and the manufacturing cost can be reduced.

  Moreover, according to such a structure, the difference of the expansion-contraction amount resulting from the difference in the thermal expansion coefficient of the lamp holder 5 and the combined body of the bezel 9 and the frame 7 can be absorbed. That is, when the temperature inside the display device 1 rises due to heat generation of the cold cathode tube 4 or other causes when the display device 1 is used, the members such as the lamp holder 5, the bezel 9 and the frame 7 are thermally expanded. In general, since the difference in coefficient of thermal expansion between the resin material and the metal material is large, the elongation amount of each side of the lamp holder 5 formed of the resin material, and the bezel 9 or the side of the frame 7 formed of the metal material. A large difference occurs in the amount of elongation.

  As described above, the first member 51 and the second member 52 constituting the lamp holder 5 can reciprocate in the longitudinal direction of the side at the connecting portion, respectively, and the screwing portion 519 and the engaging protrusion 516 are also provided. It can reciprocate in the longitudinal direction of the sides of the bezel 9 and the frame 7. Therefore, the first member 51 and the second member 52 can expand and contract without interfering or being restrained by the mating member, the bezel 9 or the frame 7 that are connected to each other.

  In this way, by combining the members having a substantially L-shape and connecting them in a stretchable manner between the sides, the four sides of the optical sheets 6 are supported and the deformation of the optical sheets 6 is suppressed. However, it is possible to absorb a difference in expansion / contraction amount of each member due to a temperature change.

  Even if the first member 51 or the second member 52 expands or contracts, there is no gap between the members 51 and 52 due to the overlapping portion, so the optical sheets 6, the lamp holder 5, and the reflection sheet It is possible to prevent dust from entering the space surrounded by or leakage of light from this space.

  Further, since the light emitted from the cold cathode tube 4 is reflected by the reflecting surface 503 of the lamp holder 5 and enters the display panel 8, it is necessary to bend the reflecting sheet to form a reflecting surface as in the conventional case ( (See FIG. 6) disappears.

  On the other hand, in order to remove the cold cathode tube 4, it is only necessary to release the connection between the frame 7 and the backlight angle 2 by a screw. The backlight angle 2 is only coupled to the frame 7, and the lamp holder 5 and the frame 7 are coupled to the bezel 9. Accordingly, when the coupling between the frame 7 and the backlight angle 2 is released and the bezel 9 is removed, the display panel 8, the frame 7, the optical sheets 6 and the lamp holder 5 are integrally detached from the backlight angle 2, Immediately the cold cathode tube 4 is exposed. In addition, since the optical sheets 6 remain supported between the lamp holder 5 and the frame 7, the optical sheets 6 do not fall apart. Thus, it is possible to make the cold cathode tube 4 removable very easily.

  This configuration can be suitably applied as a support structure for optical sheets having a particularly large size. That is, since all of the optical sheets are thin sheet-like members, bending deformation occurs due to their own weight as the size increases, and the optical sheets easily fall off. For this reason, in order to support large-sized optical sheets so as not to fall out, a structure for suppressing the bending deformation of the optical sheets is required. According to this structure, since the four sides of the optical sheets 6 are sandwiched between the lamp holder 5 and the frame 7, the occurrence of bending deformation can be suppressed even if the size of the optical sheets is increased.

  As the size increases, the difference in the amount of expansion / contraction between the lamp holder 5 and the bezel 9 and the frame 7 due to temperature change also increases. This difference in the amount of expansion / contraction increases the first of the lamp holder 5 as described above. Absorption can be performed at the connecting portion between the member 51 and the second member 52. In this way, when the lamp holder 5 is formed by combining substantially L-shaped members and is connected so as to be stretchable in the middle of each of the four sides, the temperature change can be suppressed while suppressing the bending deformation of the optical sheets 6. It is possible to absorb the difference in expansion / contraction amount of each member due to the above. Therefore, it can be suitably applied as a support structure for optical sheets having a large size.

  Next, a second embodiment will be described. FIG. 5 is an external perspective view of a lamp holder 5 ′ applied to the second embodiment of the present structure or the present display device. The lamp holder 5 ′ applied to the second embodiment includes a first member 53 and a second member 54 formed in a substantially L shape, a third member 55 and a second member formed in a substantially straight bar shape. 4 member 56. The first members 53 and the second member 54 are arranged diagonally, and the third member 55 or the fourth member 56 is disposed between the first member 53 and the second member 54, respectively. Is placed. And the front-end | tip parts of each member 53,54,55,56 are connected, Thereby, lamp holder 5 'is formed in the open quadrilateral.

  The lamp holder 5 ′ in the second embodiment and the lamp holder 5 in the first embodiment are formed by combining a lamp holder with an L-shaped member and a linear member, or by using a lamp holder. The only difference is whether or not only L-shaped members are formed in combination, and the other configurations are the same. That is, each of the members 54, 55, 56, and 57 is formed with an overlapping portion and an engagement arm at one end, and an engagement piece that engages with the engagement arm at the other end. Since other configurations have the same configuration as the lamp holder 5 in the first embodiment, the description thereof is omitted. Further, the assembly procedure and the assembly structure of the backlight angle, optical sheets, frame, display panel, and bezel are the same as those in the first embodiment, and thus the description thereof is omitted.

  According to such a configuration, substantially the same operational effects as described in the first embodiment can be obtained. Note that the first member 53 and the second member 54 formed in an L shape may be formed in the same shape. In this way, only one type of member is formed in a substantially L shape, and the types of members constituting the lamp holder 5 'can be reduced, so that an increase in manufacturing cost can be suppressed.

  Further, although not shown, a configuration may be adopted in which straight bar-shaped members (third member 55 in FIG. 5) are arranged only on the long sides of the four sides, and no straight bar-shaped members are arranged on the short sides. In this case, the short side is configured to directly connect the first member 53 and the second member 54 by designing the straight portions of the first member 53 and the second member 54 to be long. .

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to each said embodiment at all, A various change is possible in the range which does not deviate from the meaning of this invention. For example, in each of the embodiments described above, the reflection surface 503 of the lamp holders 5 and 5 ′ is configured to have an inclined surface shape having a predetermined angle with respect to the support surface 501. The angle may not be limited.
