Description

  The present disclosure relates to a display device such as a thin television device.

  The display screen of a display device such as a thin television device is desirably perpendicular to the installation surface such as a floor or a stand. For this reason, for example, it has been proposed to adjust the distance between the stand and the chassis using a screw to correct the forward or backward tilt of the display screen (see, for example, Patent Document 1).

JP 2010-128347 A

  However, in such a conventional configuration, since the distance between the stand and the chassis is adjusted by pressing the display panel with the tip of the screw, there is a risk of image quality deterioration such as unevenness in the image.

  An object of the present disclosure is to provide a display device capable of correcting the tilt in the elevation direction of the display panel without degrading the image quality.

  A display device according to the present disclosure includes a display panel, a display panel attachment target, a first contact portion provided at a different position in the vertical direction of the display panel between the back surface of the display panel and the attachment surface of the display panel, and A second contact portion, and the first contact portion and the second contact portion are provided on the back surface of the display panel itself or a convex portion provided on the back surface of the display panel, or on the attachment surface of the attachment target or the attachment surface of the attachment target. It is a provided convex part.

  Here, the first contact portion and the second contact portion being the back surface of the display panel itself means that the first contact portion or the second contact portion is flush with the back surface of the display panel (the first contact portion). Or the height of a 2nd contact part is zero). That the first contact portion and the second contact portion are the attachment surface of the attachment target means that the first contact portion or the second contact portion is flush with the attachment surface of the attachment target (the first contact portion or The height of the second contact portion is zero).

  In the display device of the present disclosure, the first contact portion and the second contact portion are provided at different positions in the vertical direction of the display panel between the back surface of the display panel and the attachment surface to be attached. The first contact portion and the second contact portion are a convex portion provided on the back surface of the display panel itself or the back surface of the display panel, or a convex portion provided on the attachment surface itself to be attached or the attachment surface to be attached. Therefore, by appropriately adjusting the height of the first contact portion and the second contact portion, the inclination of the boundary surface (contact surface) between the first contact portion and the second contact portion and the back surface of the display panel changes, The inclination of the display panel in the elevation direction is corrected to a desired value.

  According to the display device of the present disclosure, the first contact portion and the second contact portion are provided at different positions in the vertical direction of the display panel between the back surface of the display panel and the attachment surface to be attached. Since the second contact portion is a convex portion provided on the back surface of the display panel itself or the back surface of the display panel, or a convex portion provided on the attachment surface of the attachment target or the attachment surface of the attachment target. The tilt of the display panel in the elevation direction can be corrected without causing image quality degradation such as image unevenness due to the pressing force of the screw as in the conventional case.

  FIG. 1 illustrates an appearance of a display device (television device) according to an embodiment of the present disclosure as viewed from the back side. This display device has, for example, a configuration in which a back surface 1A of a display panel 1 for image display is supported by a stand 2. Here, the stand 2 corresponds to a specific example of “attachment target” in the present disclosure. In the following description and drawings, the horizontal direction of the display panel 1 is the x direction, the vertical direction of the display panel 1 is the y direction, and the opposing direction (front-rear direction) of the back surface 1A of the display panel 1 and the stand 2 is the z direction.

  For example, as shown in FIG. 2, the display panel 1 is a liquid crystal display in which a panel body 12 including a liquid crystal cell and a backlight unit (both not shown) is provided on the back surface of a transparent plate 11 such as glass or resin. It is a panel. The side surface of the panel body 12 is covered with a frame-shaped exterior member 13 such as aluminum (Al). The back surface of the panel body 12 is covered with a back cover (rear cover) 14 made of metal or resin. The outer surface of the back cover 14 corresponds to the back surface 1 </ b> A of the display panel 1.

  For example, as shown in FIG. 3, the stand 2 has a flat base 2B at the lower end of a cylindrical column 2A, and a coupling member 2C at the upper end of the column 2A. The column 2A incorporates a tilt / swivel mechanism (not shown) for performing a tilt operation for rotating the display panel 1 in the up-and-down direction At and a swivel operation for rotating the display panel 1 in the left-right direction As. The coupling member 2 </ b> C is a bracket that is attached to the upper end of the support 2 </ b> A and fixes the back surface 1 </ b> A of the display panel 1, that is, the outer surface of the back cover 14 to the stand 2. Screw holes 21 and 22 for fixing the back surface 1A of the display panel 1 are provided on the mounting surface 20 of the coupling member 2C. A notch 23 for hooking the display panel 1 using a pulley 53 described later is provided above the screw hole 22.

  The screw holes 21 and 22 are preferably arranged in a triangular shape. This is because stable and secure fixing is possible with a small number of screws. For example, the screw hole 21 is provided at the upper center of the mounting surface 20, and the screw hole 22 is provided at the lower left and lower right of the mounting surface 20.

  FIG. 4 shows the configuration of the back cover 14 shown in FIG. 2 as viewed from the outside. An attachment region 30 to which the coupling member 2C of the stand 2 is attached is provided below the center of the back cover 14. That is, the attachment region 30 is a region where the back cover 14 and the coupling member 2C of the stand 2 overlap (overlap).

  The attachment region 30 is provided with a first screw hole 31 and a second screw hole 32 for fixing the back surface 1A of the display panel 1 to the coupling member 2C of the stand 2. Above the second screw hole 32, a third screw hole 33 for attaching a pulley 53 (see FIG. 7) for hooking the display panel 1 to the stand 2 is provided. A fourth screw hole 34 for fixing the back cover 14 to the panel body 12 is provided obliquely above the second screw hole 32.

  It is preferable that the 1st screw hole 31 and the 2nd screw hole 32 are arrange | positioned at the triangle corresponding to the screw holes 21 and 22 of 2 C of coupling members. This is because stable and secure fixing is possible with a small number of screws. For example, the first screw hole 31 is provided at the upper center of the attachment region 30, and the second screw hole 32 is provided at the lower left and lower right of the attachment region 30.

  Further, the attachment region 30 is provided with a first contact portion 41 and a second contact portion 42 at different positions in the vertical direction (y direction) of the display panel 1. The first contact portion 41 and the second contact portion 42 serve as a contact point between the back surface 1A of the display panel 1 and the mounting surface 20 of the coupling member 2C of the stand 2, and as shown in FIGS. It is a convex portion provided on the back surface 1A of the display panel 1 (that is, the outer surface of the back cover 14). Thereby, in this display device, it is possible to correct the inclination of the display panel 1 in the elevation direction without degrading the image quality.

  That is, the display panel 1 is designed to be in an upright posture perpendicular (vertical) to the installation surface (horizontal plane) of the stand 2 in a state of being attached to the stand 2. However, as the development progresses, the weight of the display panel 1 increases or the center of gravity shifts, and the display panel 1 may tilt forward or backward from the vertical direction with the display panel 1 attached to the stand 2. It was. The first contact portion 41 and the second contact portion 42 have a gap between the back surface 1A of the display panel 1 and the mounting surface 20 of the coupling member 2C of the stand 2 when such an unintended inclination of the display panel 1 occurs. It has a function as a spacer for adjusting. By appropriately adjusting the heights of the first contact portion 41 and the second contact portion 42, the gap between the back surface 1A of the display panel 1 and the mounting surface 20 of the coupling member 2C of the stand 2 is adjusted in the y direction. The inclination of the boundary surface between the first contact part 41 and the second contact part 42 and the back surface 1A of the display panel 1 can be changed to reduce or reduce the unintended forward or backward inclination of the display panel 1. Become.

  Specifically, the height H41 of the first contact portion 41 is fixed. In other words, the height H41 is a value common to the plurality of display panels 1. On the other hand, the height H42 of the second contact portion 42 is adjusted so that the inclination in the elevation direction At of the display panel 1 becomes a desired value. That is, the height H42 is a value that is changed or selected so as to correct or correct the inclination according to the inclination of each display panel 1 in the elevation direction. Here, the “height” of the first contact portion 41 or the second contact portion 42 is the first contact portion 41 or the second contact portion in the facing direction (z direction) between the back surface 1A of the display panel 1 and the stand 2. 42 dimensions. The heights H41 and H42 may be different or the same. The “desired value” is an angle perpendicular to the installation surface (horizontal plane) of the stand 2 (vertical), that is, 0 ° (vertical direction) or the vicinity thereof. Specifically, for example, 0 ° ( (Vertical direction) or 1 degree backward from the vertical direction.

  The heights H41 and H42 of the first contact portion 41 and the second contact portion 42 form the first contact portion 41 and the second contact portion 42 in a mold (not shown) for manufacturing the back cover 14, for example. It is preferable to adjust by the depth of the recessed part for doing. In this way, the heights H41 and H42 of the first contact portion 41 and the second contact portion 42 can be adjusted only by the back cover 14 regardless of the configuration of the stand 2. Therefore, even if the configuration of the display panel 1 changes, the stand 2 can be shared, and the number of parts and the cost can be reduced.

  The heights H41 and H42 of the first contact part 41 and the second contact part 42 are the dimensions and weight of the display panel 1, the position of the mounting region 30 in the back cover 14, and the y of the first contact part 41 and the second contact part 42. It is possible to set appropriately considering the distance in the direction. In the present embodiment, for example, the diagonal size of the display panel 1 is 40 inches, the weight is 13.1 kg, and the total weight of the display panel 1 and the stand 2 is 17.0 kg. As shown in FIG. 4, the first contact portion 41 is on the longitudinal center line CL <b> 1 of the back cover 14. The y-direction distance D1 between the first contact portion 41 and the lateral center line CL2 of the back cover 14 is, for example, 182.20 mm. The y-direction distance D2 between the second contact portion 42 and the lateral center line CL2 of the back cover 14 is, for example, 227.20 mm. The x-direction distance D3 between the two second contact portions 42 is, for example, 260.00 mm. In this case, the height H41 (fixed) of the first contact portion 41 is, for example, 2.5 mm, the height H42 (variable) of the second contact portion 42 is, for example, 0.5 mm, and the difference between the heights H41, H42 is, for example, 2.0 mm.

  Such convex portions of the first contact portion 41 and the second contact portion 42 are formed from the viewpoint of improving the appearance of the back cover 14, for example, as shown in FIGS. 4 to 6, the first screw hole 31 and the second contact portion 42. It can also serve as the seating surface of the screw hole 32. Although omitted in FIGS. 4 and 5, protrusions serving as seating surfaces for the third screw hole 33 and the fourth screw hole 34 may be provided around the third screw hole 33 and the fourth screw hole 34 as necessary. A portion may be provided. At this time, the height of the convex portions serving as the seating surfaces of the third screw hole 33 and the fourth screw hole 34 is used to correct or correct the inclination of the display panel 1 by the convex portions of the first contact portion 41 and the second contact portion 42. It is desirable that it does not hinder the function.

  Hereinafter, a method of attaching the display panel 1 to the stand 2 will be described.

  First, as shown in FIG. 2, the panel body 12 is installed on the back surface of the transparent plate 11, and the side surface of the panel body 12 is covered with a frame-shaped exterior member 13. Next, the back cover 14 is fixed to the panel body 12 using the fourth screw holes 34, and the back surface of the panel body 12 is covered with the back cover 14. Thereby, the display panel 1 is formed.

  Moreover, as shown in FIG. 3, the lower end of the support | pillar 2A is fixed to the foundation 2B. Subsequently, as illustrated in FIG. 7, the upper end of the support 2 </ b> A is accommodated in the accommodating portion 2 </ b> D of the coupling member 2 </ b> C and is fixed by the screw 2 </ b> E. Thereby, the stand 3 is formed.

  After that, as shown in FIG. 8, a pulley 53 is attached to the third screw hole 33 of the back cover 14, and the display panel 1 is attached to the notch 23 of the attachment surface 20 of the coupling member 2 </ b> C of the stand 2 using this pulley 53. Hang on.

  After the display panel 1 is hooked on the notch 23 of the coupling member 2C of the stand 2, as shown in FIG. 7, the back surface 1A of the display panel 1 and the stand are used using the screw hole 21 and the first screw hole 31. The two coupling members 2 </ b> C are fixed with screws 61. Similarly, as shown in FIG. 8, the back surface 1 </ b> A of the display panel 1 and the coupling member 2 </ b> C of the stand 2 are fixed by screws 62 using the screw holes 22 and the second screw holes 32.

  Here, as shown in FIG. 9, when the display panel 1 and the stand 2 are coupled only by the screws 61 and 62 and the first contact portion 41 and the second contact portion 42 are not provided, the arrow A1 As shown in FIG. 5, there is a possibility that the upper part of the display panel 1 is inclined forward. Alternatively, although not shown, the upper side of the display panel 1 may be inclined backward. Such a forward or backward tilt of the display panel 1 is caused by the weight of the display panel 1 itself without using a tilt mechanism (not shown) built in the column 3A.

  In such a case, conventionally, the stand 2 has been dealt with by providing a rib (not shown) or the like for tilt correction. However, conventionally, since the rib is provided only at one position in the vertical direction (y direction) of the display panel 1, the effect of tilt correction cannot be sufficiently obtained. Further, when the configuration of the display panel 1 is changed, it is difficult to make the stand 2 common, which causes an increase in the number of parts and an increase in cost.

  On the other hand, in the present embodiment, as shown in FIG. 10, different positions in the vertical direction (y direction) of the display panel 1 between the back surface 1A of the display panel 1 and the mounting surface 20 of the stand 2. The first contact part 41 and the second contact part 42 are provided. The first contact portion 41 and the second contact portion 42 are convex portions provided on the back surface 1 </ b> A (the outer surface of the back cover 14) of the display panel 1. Accordingly, by appropriately adjusting the heights H41 and H42 of the first contact portion 41 and the second contact portion 42, the boundary surface between the first contact portion 41 and the second contact portion 42 and the back surface 1A of the display panel 1 ( The inclination of the contact surface P changes, and the inclination of the display panel 1 in the elevation direction is corrected or corrected to a desired value. Here, since the first contact portion 41 and the second contact portion 42 are convex portions provided on the back surface 1A of the display panel 1 (that is, the outer surface of the back cover 14), the boundary surface (contact surface) P Is a plane connecting the lower end of the convex portion of the first contact portion 41 and the lower end of the convex portion of the second contact portion 42.

  Further, in this embodiment, it is not necessary to press the display panel with screws or the like as in the conventional configuration described in Patent Document 1. As a result, image quality such as unevenness does not occur in the displayed image. Further, there is no possibility of damaging the display panel components due to overtightening of the screws.

  As an actual tilt correction method, for example, the tilt angle from the vertical direction to the front or rear is actually measured in a state where each display panel 1 is mounted on the stand 2 before shipment. On the other hand, several types of back cover 14 having different heights H42 of the convex portions of the second contact portion 42 are prepared, and the back cover 14 is replaced with another back cover 14 based on the measurement result. Can be brought close to a desired target value. At this time, since both the first contact portion 41 and the second contact portion 42 are provided on the back cover 14, it is not necessary to change the stand 2 at all, and only the back cover 14 needs to be replaced. Therefore, the work becomes easy and the cost is greatly reduced.

  Thus, in the present embodiment, the first contact is made at a different position in the vertical direction (y direction) of the display panel 1 between the back surface 1A of the display panel 1 and the mounting surface 20 of the stand 2 to be mounted. A portion 41 and a second contact portion 42 are provided. As the first contact portion 41 and the second contact portion 42, convex portions are provided on the back surface 1A of the display panel 1, that is, the outer surface of the back cover 14. Therefore, it is possible to correct the inclination of the display panel 1 in the elevation direction without degrading the image quality.

  In addition, since both the first contact portion 41 and the second contact portion 42 are provided on the back cover 14, it is not necessary to change the configuration of the stand 2, and only the back cover 14 and the first contact portion 41 and the second contact portion 42 are provided. The heights H41 and H42 of the two contact portions 42 can be adjusted. Therefore, the number of parts and the cost can be reduced by using the stand 2 in common.

  In the above-described embodiment, the case where both the first contact portion 41 and the second contact portion 42 are convex portions provided on the back surface 1A of the display panel 1 (that is, the outer surface of the back cover 14) has been described. . However, for example, as shown in FIG. 11, the first contact portion 41 is flush with the back surface 1A of the display panel 1 (the outer surface of the back cover 14) (H41 = 0 mm). Only 42 may be a convex portion. In other words, the first contact portion 41 is not limited to a convex portion as long as the height H41 is a fixed surface (a surface in which the height H41 is commonly set for the plurality of display panels 1), and the back surface of the display panel 1 1A (the outer surface of the back cover 14) itself may be used. However, when the thickness of the display panel 1 is extremely thin, it is desirable that the first contact portion 41 is a convex portion in consideration of the height of the screws 61 and 62.
