The reflector 111f may be located between the frame 13 and the light guide plate 111e and is supported by the frame 13.

[0051] Thus, the light from the light source 111b' can be provided to the display panel 11 through the light guide plate 111e and the optical sheet 112. On the other hand, the display panel 11 of this invention can also be an OLED panel or other types of panels that do not require the aforementioned backlight unit 110'.

[0052] Reference Figure 6 and Figure 7 The front bracket 41 can be generally disc-shaped. The front bracket 41 can be attached to the back cover 15 of the display 10 (see reference). Figure 2 The front bracket 41 is parallel to the back of the back cover 15. The front bracket 41 may be referred to as the first bracket 41.

[0053] A plurality of joints 41a, 41b, and 41c may be formed on the edge of the front bracket 41. The plurality of joints 41a, 41b, and 41c may be recessed from the back of the front bracket 41 towards the front.

A hole 41h may be formed at the center of the front bracket 41. The shape of the hole 41h may be the same as the cross-sectional shape of the body 43b of the pivot shaft 43. The pivot shaft 43 may pass through the hole 41h. The pivot shaft 43 and the front bracket 41 may rotate together about the axial direction of the pivot shaft 43.

[0055] A front grab 44G may be located between the head 43a of the pivot 43 and the front face of the front bracket 41. The hole 44Gh of the front grab 44G may be aligned with the hole 41h of the front bracket 41 and has the same shape as the hole 41h. The body 43b of the pivot 43 may pass through the holes 44Gh and 41h. A protrusion 44Gf may protrude from the front grab 44G toward the front bracket 41 and be inserted into and fixed to the slot 41f or hole 41f of the front bracket 41. The protrusions 44Gf may be spaced apart from each other at 90-degree intervals. At least one washer 44W may be located between the front grab 44G and the front bracket 41 and has a circular hole 44Wh. The body 43b of the pivot 43 may pass through the hole 44Wh of the washer 44W. On the other hand, the portion of the front bracket 41 with holes 41h and 41f can be referred to as the pressed portion 41P. On the other hand, at least one hole 41M, 41N, or 41G can be formed on the outside of the pressed portion 41P.

[0056] The rear bracket 42 can be located behind the front bracket 41. The rear bracket 42 can be referred to as the second bracket 42. The rear bracket 42 can be U-shaped in general. The rear bracket 42 may include a mounting base 42M, a first wing 42L, and a second wing 42R.

[0057] The mounting base 42M can face the front bracket 41. The circular hole 42Mh of the mounting base 42M can be aligned with the hole 41h of the front bracket 41. The body 43b of the pivot shaft 43 can pass through the hole 42Mh of the mounting base 42M and can rotate relative to the hole 42Mh. In other words, even if the pivot shaft 43 rotates, the rear bracket 42 can remain stationary. At least one washer 45W can be located between the mounting base 42M of the front bracket 41 and the rear bracket 42, and has a circular hole 45Wh. The body 43b of the pivot shaft 43 can pass through the hole 45Wh of the washer 45W.

[0058] The first wing 42L can extend rearward from one side (left side) of the fixed base 42M. The first wing 42L can form the left side of the rear bracket 42. The first wing 42L can be referred to as the left wing 42L.

[0059] The second wing 42R can extend rearward from the other side (right side) of the mounting base 42M. The second wing 42R can form the right side of the rear bracket 42. The second wing 42R can be referred to as the right wing 42R.

[0060] The components 45G, 45A, 45B, 45C, 45D, and 45E, described later, can be located between the first wing 42L and the second wing 42R, and can be combined with the fixed base 42M.

[0061] Reference Figure 7 and Figure 8 The rear grab 45G can be located behind the mounting base 42M. A protrusion 45Gf can protrude from the rear grab 45G toward the mounting base 42M and insert into and secure it to the slot 42Mf or hole 42Mf of the mounting base 42M (see reference). Figure 6 The protrusions 45Gf can be spaced apart from each other at 90-degree intervals. The circular hole 45Gh of the rear grip 45G can be aligned with the hole 42Mh of the mounting base 42M. The body 43b of the pivot shaft 43 can pass through the holes 42Mh and 45Gh, and can rotate relative to the holes 42Mh and 45Gh. In other words, even if the pivot shaft 43 rotates, the rear bracket 42 and the rear grip 45G can remain stationary.

[0062] A plurality of mounting holes 45Ga and a plurality of slots 45Gb may be formed around the hole 45Gh of the rear gripper 45G. The mounting holes 45Ga and slots 45Gb may be alternately arranged along the boundary of the hole 45Gh. The mounting holes 45Ga may be spaced apart from each other at 90-degree intervals, and the slots 45Gb may be spaced apart from each other at 90-degree intervals. In the arrangement direction of the mounting holes 45Ga and slots 45Gb, the length of the slot 45Gb may be greater than the length of the mounting hole 45Ga.

[0063] The disc 45A can be located behind the rear gripper 45G and can have a hole 45Ah through which the body 43b of the pivot 43 passes. The shape of the hole 45Ah can be the same as the cross-sectional shape of the body 43b, and the disc 45A can rotate together with the pivot 43. A plurality of protrusions 45At can protrude from the side of the disc 45A facing the rear gripper 45G (front side) and can be spaced apart from each other in the circumferential direction of the disc 45A. The protrusions 45At can be spaced apart from each other at 90-degree intervals. The size of the protrusions 45At can be the same as or correspond to the size of the fixing hole 45Ga. If the protrusions 45At are inserted into the fixing hole 45Ga, the rotation of the disc 45A and the pivot 43 can be restricted by the rear gripper 45G. If the protrusions 45At are inserted into the slot 45Gb, the disc 45A and the pivot 43 can rotate within the slot 45Gb.

[0064] A disc spring 45B may be located behind the disc 45A and may have a circular hole 45Bh through which the body 43b of the pivot shaft 43 passes. The disc spring 45B may be elastic and may protrude forward or backward. The disc spring 45B may generate an elastic force in the axial direction of the pivot shaft 43. For example, a pair of disc springs 45B may be provided. A first disc spring 45Ba may protrude rearward, and a second disc spring 45Bb may protrude forward.

[0065] A cap 45C can be located behind the disc spring 45B and can have a hole 45Ch through which the body 43b of the pivot shaft 43 passes. The shape of the hole 45Ch can be the same as the cross-sectional shape of the body 43b. The cap 45C can be fixed to the body 43b and can press the disc spring 45B and the disc 45A towards the rearward gripping part 45G. The cap 45C, such as a nut, can be threaded onto the body 43b. A first washer 45D can be located between the disc 45A and the disc spring 45B and can have a circular hole 45Dh through which the body 43b of the pivot shaft 43 passes. A second washer 45E can be located between the disc spring 45B and the cap 45C and can have a circular hole 45Eh through which the body 43b of the pivot shaft 43 passes.

[0066] Therefore, the front bracket 41 can rotate together with the pivot 43, the front grip 44G, the disc 45A, and the cap 45C. The front bracket 41 can rotate independently of the rear bracket 42, the rear grip 45G, the disc spring 45B, and the washers 44W, 45D, and 45E. In other words, even if the front bracket 41 rotates, the rear bracket 42, the rear grip 45G, the disc spring 45B, and the washers 44W, 45D, and 45E can remain stationary.

[0067] The pivot axis 43 provides the pivot axis of the front bracket 41. Under the elastic force of the disc spring 45B, the pivot angle of the front bracket 41 can be maintained as long as the front bracket 41 is not subjected to a force exceeding a specified level.

[0068] A first protrusion 41L can protrude rearward from the front bracket 41. A second protrusion 41R can protrude rearward from the front bracket 41. A stopper 42S can protrude from the top of the fixed base 42M and can be located on the rotational trajectory of the first protrusion 41L and the second protrusion 41R. The stopper 42S can restrict the pivoting of the front bracket 41 by interfering with the first protrusion 41L or the second protrusion 41R. The first protrusion 41L and the second protrusion 41R can be spaced 180 degrees apart from each other with respect to the pivoting axis of the front bracket 41, and the front bracket 41 can pivot within the range of +90 degrees to -90 degrees.

[0069] During the pivoting of the front bracket 41, the user can feel a tightening sensation from the fastening of the protrusion 45At and the mounting hole 45Ga or the fastening of the protrusion 45At and the slot 45Gb. For example, when the protrusion 45At disengages from the slot 45Gb and inserts into the mounting hole 45Ga, the user can perceive that the front bracket 41 is at an angle of 0 degrees, +90 degrees, or -90 degrees.

[0070] Reference Figure 8 and Figure 9 The retainer 46 may be located behind the mounting base 42M of the rear bracket 42. The retainer 46 may be located between the wings 42L and 42R of the rear bracket 42. The retainer 46 may be referred to as an ankle joint 46, a hand 46, or a grab 46. The retainer 46 may include a front portion 461, a middle portion 462, and a rear portion 463. The front portion 461, the middle portion 462, and the rear portion 463 may be formed as a single unit.

The first portion 461a can extend from the third portion 461c toward the mounting base 42M and can face the first wing 42L. The second portion 461b can extend from the third portion 461c toward the mounting base 42M and can face the second wing 42R.

[0072] The intermediate portion 462 may form the central portion of the retainer 46. The intermediate portion 462 may be located behind the front portion 461. The intermediate portion 462 may extend rearward from the third portion 461c of the front portion 461. Alternatively, the intermediate portion 462 may be omitted. In this case, the rear portion 463 may be directly attached to the front portion 461.

[0073] The rear portion 463 can form the rear portion of the retainer 46. The rear portion 463 can be located behind the middle portion 462. The rear portion 463 can extend rearward from the middle portion 462. The rear portion 463 can be generally annular in shape. The hole 463H can be formed by penetrating the center of the rear portion 463 in a vertical direction. The rear portion 463 can be engaged with the support wall 50. The rear portion 463 can rotate relative to the support wall 50.

[0074] The tilt shaft 47 can extend in a direction intersecting with the wings 42L and 42R of the rear bracket 42.

The head 47a of the tilt shaft 47 can form one end of the tilt shaft 47 and can be inserted into the hole 42Lh fixed to the first wing 42L. A portion 47b of the tilt shaft 47 can form the other end of the tilt shaft 47 and can be inserted into the hole 42Rh fixed to the second wing 42R. A fastening member 47F, such as a nut, can be threaded onto the portion 47b of the tilt shaft 47 protruding from the second wing 42R.

[0075] At this point, a circular first hole 461ah can be formed in the first portion 461a, and a circular second hole can be formed in the second portion 461b. An inclined shaft 47 can pass through both the first hole 461ah and the second hole. The inclined shaft 47 and the brackets 41 and 42 coupled thereto can rotate relative to the retainer 46.

[0076] The elastic member 470 may be located between the first portion 461a and the second portion 461b of the retainer 46. The elastic member 470 may be wound multiple times around the outer peripheral surface of the inclined shaft 47 and may be elastic. The elastic member 470 may be a coil-shaped spring. The coil section 471 of the elastic member 470 may be the portion of the elastic member 470 wound around the outer peripheral surface of the inclined shaft 47. The support section 472 of the elastic member 470 extends from one end of the coil section 471, forming one end of the elastic member 470, and may be supported on the inner side of the front portion 461 of the retainer 46. The engagement section 473 of the elastic member 470 may extend from the other end of the coil section 471, forming the other end of the elastic member 470, and may be supported on the rear bracket 42. The support portion 42F may protrude rearward from the lower side of the fixing seat 42M of the rear bracket 42 and may be adjacent to the first wing 42L. The locking section 473 can be locked into the groove 42Fg of the support part 42F.

[0077] A disc spring 470S may be located between the elastic member 470 and the second part 461b. An inclined shaft 47 may pass through the disc spring 470S. The disc spring 470S may protrude toward the elastic member 470 or the second part 461b and may be elastic. The disc spring 470S may generate an elastic force along the axial direction of the inclined shaft 47. A washer 470W may be located between the second part 461b and the second wing 42R and may have a circular hole through which the inclined shaft 47 passes.

[0078] Thus, the front bracket 41 and the rear bracket 42 can rotate together with the tilting shaft 47 and the fastening member 47F (see reference). Figure 9 (RDa, RDb). The tilting shaft 47 can provide the axis of rotation of the brackets 41, 42 relative to the retainer 46. The tilting shaft 47 can provide the tilting axis of the brackets 41, 42. Under the elastic force of the disc spring 470S, the tilting angle of the brackets 41, 42 can be maintained as long as the brackets 41, 42 are not subjected to a force exceeding a specified level.

[0079] Pin 46P can be fixed to the first part 461a and / or the second part 461b. The first pin 46Pa can protrude from the outer side of the first part 461a. The second pin 46Pb can protrude from the outer side of the second part 461b.

[0080] Guide grooves 42G can be formed on the first wing 42L and / or the second wing 42R. A first guide groove 42Ga can be formed from the rear end of the first wing 42L toward the inner side of the first wing 42L. A second guide groove 42Gb can be formed from the rear end of the second wing 42R toward the inner side of the second wing 42R. The first groove 42G1 of the guide groove 42G can be formed in an arc shape from a reference point 42G0 along a first rotation direction RDa. The second groove 42G2 of the guide groove 42G can be formed in an arc shape from a reference point 42G0 along a second rotation direction RDb opposite to the first rotation direction Rda.

[0081] Here, the tilting shaft 47 can rotate in either a first rotation direction Rda or a second rotation direction RDb. During the rotation of the tilting shaft 47 in the first rotation direction Rda, the pin 46P can move relative to it in the second groove 42G2. As the second groove 42G2 engages with the pin 46P, the rotation (tilting) of the tilting shaft 47 and the brackets 41, 42 connected thereto can be restricted. During the rotation of the tilting shaft 47 in the second rotation direction RDb, the pin 46P can move relative to it in the first groove 42G1. As the first groove 42G1 engages with the pin 46P, the rotation (tilting) of the tilting shaft 47 and the brackets 41, 42 connected thereto can be restricted.

[0082] Therefore, brackets 41 and 42 can tilt up and down within a specified angle range. For example, brackets 41 and 42 can tilt within a range of +25 degrees to -25 degrees.

The second edge 492 may be referred to as the rear rim 492 or the second wall 292.

[0097] The first connecting portion 493 can protrude rearward from the second edge 492. The first connecting portion 493 can face the first wing 42L of the rear bracket 42. The second fastening member F2 can pass through the hole 493h of the first connecting portion 493 and be fastened to the hole 42Lf of the first wing 42L.
