Therefore, the edge P 2 of the base section 42 A is prevented from interfering with a rotation locus R of the board 30 around the rotation axis A 3 as a center.
- the distance L is a distance between P 1 and P 2 in a direction perpendicular to the side 40 AD with the hook sections 41 A and 41 D disposed thereon of the mounting region 40 .

Description
- The present application is a continuation of U.S. patent application Ser. No. 13/346,928, filed Jan. 10, 2012, which claims priority from Japanese Patent Application No. JP 2011-010407 filed in the Japanese Patent Office on Jan. 21, 2011, the entire contents of which are incorporated herein by reference.
- The present technology relates to a display such as a television, and an electronic unit.
- A board including a drive circuit is mounted in a display such as a television or an electronic unit. In related art, such a board is fixed by tightening screws at four corners or more, and the cost of screws and working time for tightening screws are necessary. For example, in Japanese Unexamined Patent Application Publication No. 2009-295738, while a mountain-shaped projection is provided in a downward direction on an L-shaped bracket, a metal through-hole is provided at a corner of a board, and the mountain-shaped projection is inserted into the metal through-hole to fix the board without screws.
- However, in Japanese Unexamined Patent Application Publication No. 2009-295738, the strength of the L-shaped bracket is not sufficient, and the L-shaped bracket may be easily deformed and defective during transport or the like.
- It is desirable to provide a display capable of inhibiting deformation of a component during transport or the like, and an electronic unit including the display.
- According to an embodiment of the technology, there is provided a display including: a main section; and a board-mounting plate disposed on one surface of the main section, and having a board-mounting region on a main surface on a side opposite to a side facing the main section, in which the board-mounting plate includes, at corners at both ends of a side of the mounting region, hook sections allowing corners of a board to be hooked thereto, and the hook sections each are fixed to the main surface on two sides of the corner of the mounting region.
- According to an embodiment of the technology, there is provided an electronic unit including: a main section; and a board-mounting plate disposed on one surface of the main section, and having a board-mounting region on a main surface on a side opposite to a side facing the main section, in which the board-mounting plate includes, at corners at both ends of a side of the mounting region, hook sections allowing corners of a board to be hooked thereto, and the hook sections each are fixed to the main surface on two sides of the corner of the mounting region.
- In the display according to the embodiment of the technology, or the electronic unit according to the embodiment of the technology, while the board is inclined with respect to the main surface, the corners at both ends of a side of the board are slid into the hook sections. Next, the board is rotated around ends of the hook sections as rotation axes toward the main surface. Thus, the corners of a board are hooked to the hook sections, and the board is positioned in the mounting region.
- In the display according to the embodiment of the technology, or the electronic unit according to the embodiment of the technology, the hook sections allowing the corners of a board to be hooked thereto are disposed at corners at both ends of a side of the mounting region, and the hook sections are fixed to the main surface on two sides of the corner of the mounting region; therefore, the strength of the hook sections is enhanced, and deformation of the hook sections during transport or the like is allowed to be inhibited.
- It is to be understood that both the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the technology as claimed.
- The accompanying drawings are included to provide a further understanding of the disclosure, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments and, together with the specification, serve to explain the principles of the technology.

Adisplay 1 has, for example, a configuration in which adisplay section 10 is supported by astand 11. A frame-shaped exterior member (a so-called bezel) is disposed on a front surface of thedisplay section 10. A board-mounting plate 20 for mounting aboard 30 with a drive circuit is disposed on a rear surface of thedisplay section 10. The whole rear surface of thedisplay section 10 and the whole board-mounting plate 20 are covered with arear cover 13. It is to be noted that thedisplay section 10 corresponds to a specific example of “a main section” in the technology. - The
display section 10 includes, for example, a backlight unit (not illustrated) on a rear surface of a liquid crystal panel (not illustrated). - The board-
mounting plate 20 is configured of, for example, a metal plate made of aluminum (Al), iron (Fe), or the like. It is to be noted that the board-mounting plate 20 may be provided separately from thedisplay section 10, or may also serve as an enclosure (a so-called back chassis) of the backlight unit (not illustrated) of thedisplay section 10. - A
mounting region 40 for theboard 30 is disposed in amain surface 20A, on a side opposite to a side facing thedisplay section 10, of the board-mounting plate 20. Themounting region 40 is appropriately provided according to the number ofboards 30 mounted on the board-mounting plate 20, the dimensions and shape of eachboard 30. -
FIG. 3 illustrates an enlarged view of onemounting region 40 illustrated inFIG. 2 .FIG. 4 illustrates a state where theboard 30 is removed from themounting region 40 illustrated inFIG. 3 . It is to be noted that inFIGS. 3 to 11 , and later drawings, a horizontal direction, a vertical direction, and a direction orthogonal to themain surface 20A (a height direction) are represented by x, y, and z, respectively. - The
board 30 is configured of, for example, a printed circuit board, and has a horizontally-oriented rectangular shape with fourcorners chip 31 is mounted on theboard 30. - The
mounting region 40 has a horizontally-oriented rectangular shape with fourcorners board 30 is mounted on themounting region 40, themounting region 40 is a recessed section which is lower in height than a peripheral region of themain surface 20A. -
Hook sections corners mounting region 40.Base sections hook sections upstanding section 43A and a secondupstanding section 43B are disposed between thehook sections screw holes hook sections upstanding section 43A and the secondupstanding section 43B, and four surrounding sides 40AB, 40BC, 40CD, and 40AD are preferably as small as possible. - The
hook sections corners board 30 to be hooked thereto, and are rectangular bump sections formed by embossing on the board-mountingplate 20. Thehook section 41A is fixed to themain surface 20A on two sides 40AB and 40AD of thecorner 40A of the mountingregion 40. Thehook section 41D is fixed to themain surface 20A on two sides 40AD and 40CD of thecorner 40D of the mountingregion 40. Therefore, in the display, deformation of thehook sections - The
hook sections region 40, because when theboard 30 is mounted, rotation on an xy plane of theboard 30 is allowed to be inhibited. - The
base sections corners board 30, respectively, and confine a z-direction position of theboard 30 with thehook sections base sections plate 20. - The first
upstanding section 43A and the secondupstanding section 43B confine a y-direction position of theboard 30, and controls rotation on the xy plane of theboard 30, and are disposed on a side with thehook sections region 40, and are orthogonal to themain surface 20A, and abut against a side surface on the side 30AD of theboard 30. The firstupstanding section 43A and the secondupstanding section 43B are formed by a cutting-bending process on the board-mountingplate 20. - The second
upstanding section 43B is disposed on a more inner side than the firstupstanding section 43A. In other words, the secondupstanding section 43B is disposed in a position shifted from the firstupstanding section 43A in a direction toward the side 40BC facing the side 40AD with thehook sections region 40. On the other hand, theboard 30 includes, on the side 30AD, anotch 33B allowing the secondupstanding section 43B to be inserted thereinto. Therefore, an x-direction position of theboard 30 is allowed to be confined. - The screw holes 44B and 44C fix the
corners board 30 byscrews 60, and are disposed on the side 40BC facing the side 40AD with thehook sections region 40. The screw holes 44B and 44C are preferably disposed on top surfaces ofbump sections corners region 40, respectively, to prevent thescrews 60 from causing damage to thedisplay section 10. Thebump sections plate 20.Dowels board 30 may be disposed on the top surfaces of thebump sections -
FIG. 5 illustrates a sectional configuration of thehook section 41A. Two sides 40AB and 40AD of thehook section 41A are closed by aside wall section 47 fixed to themain surface 20A as described above. Thus, thehook section 41A is fixed to themain surface 20A on the two sides 40AB and 40AD; therefore, compared to an L-shaped bracket in related art, mechanical strength is enhanced, and defective components caused by deformation during transport or the like are reduced. On the other hand, the other two sides of thehook section 41A are open ends, and thecorner 30A of theboard 30 is allowed to be contained in a gap G between thehook section 41A and themain surface 20A. It is to be noted that thehook section 41D has the same configuration as that of thehook section 41A. - A
guide projection 48A projected toward a side opposite to themain surface 20A is disposed at an end of thehook section 41A. When theguide projection 48A is provided, thecorner 30A of theboard 30 is allowed to be guided to thehook section 41A, and workability is allowed to be improved. It is to be noted that as in the case of thehook section 41A, aguide projection 48D (not illustrated) is disposed at an end of thehook section 41D. - Moreover, the
hook section 41A includes a projectedsection 49A on a surface facing themain surface 20A, and the projectedsection 49A abuts against a surface of thecorner 30A of theboard 30. A recessedsection 39A (not illustrated inFIG. 5 , refer toFIG. 11 ) allowing the projectedsection 49A to be inserted thereinto is disposed on the surface of thecorner 30A of theboard 30. Therefore, positioning of theboard 30 is performed more easily. It is to be noted that as in the case of thehook section 41A, thehook section 41D includes a projectedsection 49D (not illustrated). -
FIG. 6 illustrates a sectional configuration taken along a line VI-VI ofFIG. 3 . A heat dissipation pad (thermal pad) 50 is disposed between themain surface 20A of the board-mountingplate 20 and the rear surface of theboard 30. Theheat dissipation pad 50 is disposed directly below thechip 31 mounted on theboard 30, and releases heat generated in thechip 31 to the board-mountingplate 20. Theheat dissipation pad 50 is made of a material with electrical insulation and high thermal conductivity, for example, a urethane-based material. It is to be noted that instead of theheat dissipation pad 50, a heat dissipation sheet may be provided. -
FIGS. 7 to 11 illustrate steps of mounting theboard 30 onto such a mountingregion 40 in order. First, as illustrated inFIG. 7 , theboard 30 is held above the mountingregion 40 while being inclined with respect to themain surface 20A, and as indicated by an arrow A1, thecorners board 30 are slid into thehook sections - At this time, as illustrated in
FIG. 8 , first, when the side 30AD of theboard 30 abuts against theguide projection 48A at the end of thehook section 41A, as indicated by an arrow A2, thecorner 30A of theboard 30 is allowed to be easily slid into thehook section 41A. It is to be noted that although not illustrated, the same applies to the case of thehook section 41D. - Next, as illustrated in
FIG. 9 , a side surface on the side 30AD of theboard 30 abuts against the firstupstanding section 43A and the secondupstanding section 43B to confine the y-direction position of theboard 30, and to control rotation on the xy plane of theboard 30. Moreover, the x-direction position of theboard 30 is confined by inserting the secondupstanding section 43B into thenotch 33B of theboard 30. - Then, continuing with
FIG. 9 , theboard 30 is rotated around the ends of thehook sections main surface 30A in a downward direction indicated by an arrow A4. Therefore, as illustrated inFIG. 10 , thecorners board 30 are hooked to thehook sections corners board 30 abut against thebase sections board 30 in the mountingregion 40. - For information, in related art, a method of fixing a board to a bracket by sliding the board in a horizontal direction is performed. However, in the fixing method by sliding, a region where the board touches the bracket during sliding the board is an unmountable region; therefore, it is necessary to increase the size of the board accordingly, thereby causing an increase in cost. Moreover, there are issues that during sliding the board, the heat dissipation pad bonded to the rear surface of the board is displaced, and the chip mounted on the rear surface of the board is damaged and defective. Further, as it is necessary to have a clearance between the board and the bracket, chattering noise is generated.
- On the other hand, in the embodiment, an unmountable region in the
board 30 includes only regions contacting thehook sections base sections bump sections board 30 is preventable. Moreover, as illustrated inFIG. 9 , theboard 30 is mounted by rotation; therefore, there is no possibility that theheat dissipation pad 50 on the rear surface of theboard 30 is displaced, and the chip mounted on the rear surface of theboard 30 is damaged and defective. Further, while the front surface of theboard 30 is in contact with thehook sections board 30 is in contact with thebase sections board 30 to be deflected, thereby reducing chattering noise. -
FIG. 11 illustrates a sectional configuration taken along a line XI-XI ofFIG. 10 . A distance L between an end P1 of thehook section 41A and an edge P2 of a surface, abutting against the rear surface of thecorner 30A of theboard 30, of thebase section 42A preferably satisfies L>0 (mm). Therefore, the edge P2 of thebase section 42A is prevented from interfering with a rotation locus R of theboard 30 around the rotation axis A3 as a center. It is to be noted that the distance L is a distance between P1 and P2 in a direction perpendicular to the side 40AD with thehook sections region 40. - After that, the
corners board 30 are fixed to the board-mountingplate 20 with use of thescrews 60 inserted into the screw holes 44B and 44C. Thus, mounting of theboard 30 onto the mountingregion 40 is completed. - Thus, in the embodiment, the
hook sections corners region 40, respectively, and thehook section 41A is fixed to themain surface 20A on two sides 40AB and 40AD of thecorner 40A, and thehook section 41D is fixed to themain surface 20A on the sides 40AD and 40CD of thecorner 40D. Therefore, the strength of thehook sections hook sections - Moreover, the
corners board 30 are hooked to thehook sections board 30 is rotated around the ends of thehook sections main surface 20A; therefore, theboard 30 is allowed to be easily positioned in the mountingregion 40, thereby improving workability in board installation. - Further, during an operation until fixing the position of the
board 30, thecorners board 30 are allowed to be hooked to thehook sections board 30. Therefore, a chip mounted on the rear surface of theboard 30 is allowed to be prevented from being damaged and defective during positioning of theboard 30. - In addition, two
corners board 30 are allowed to be fixed without screws, and the number of components and cost of components are allowed to be reduced. Further, cost reduction is achievable by reducing working time for tightening screws. - Application examples of the display described in the above-described embodiment will be described below.
