[0040] Referring to FIGS. 1 and 2, the display device (1) may include a display panel (10), a side frame (20), a backlight unit, a frame (80), and a back cover (90).

[0041] A display panel (10) can define the front of a display device (1) and can display an image. The display panel (10) can display an image by having multiple pixels output RGB (Red, Green, or Blue) for each pixel in time. The display panel (10) can be divided into an active area where an image is displayed and a de-active area where an image is not displayed. The display panel (10) may include a front substrate and a rear substrate that are opposite each other with a liquid crystal layer in between. The display panel (10) may be referred to as an LCD panel (10). Alternatively, the display panel (10) may be a different type of panel, such as an OLED panel, in which case the backlight unit described above and below may be omitted.

[0042] The front substrate may include a plurality of pixels composed of red, green, and blue subpixels. The front substrate may output light corresponding to the color red, green, or blue according to a control signal.

[0043] The rear substrate may include switching elements. The rear substrate may switch the pixel electrode. For example, the pixel electrode may change the molecular arrangement of the liquid crystal layer according to a control signal input from the outside. The liquid crystal layer may include liquid crystal molecules. The arrangement of the liquid crystal molecules may change in correspondence with the voltage difference generated between the pixel electrode and the common electrode. The liquid crystal layer may transmit light provided by the backlight unit to the front substrate or block it.

[0044] The side frame (20) may extend along the edge of the display panel (10). The side frame (20) may cover the edge of the display panel (10). For example, the side frame (20) may include a plastic or metal material. The side frame (20) may be referred to as a guide panel (20).

[0045] The backlight unit may be located at the rear of the display panel (10). The backlight unit may be located at the front of the frame (80) and may be coupled to the frame (80). The backlight unit may be driven in a full driving mode or in a partial driving mode such as local dimming or impulsive. The backlight unit may include light sources that provide light forward, a substrate (40) on which the light sources are mounted, lenses (53) covering the light sources, a reflective sheet (60) covering the front of the substrate (40), and an optical part (30) located at the front of the reflective sheet (60).

[0046] The optical unit (30) may be opposite to the display panel (10) with respect to the side frame (20). The optical unit (30) may evenly transmit light from the light source to the display panel (10). The optical unit (30) may include a diffuser plate (31) and an optical sheet (32).

[0047] A diffuser plate (31) may be positioned between a reflective sheet (60) and an optical sheet (32). The diffuser plate (31) may diffuse the light of the light source. Additionally, an air gap may be formed between the reflective sheet (60) and the diffuser plate (31). The air gap may function as a buffer, and the light of the light source may spread widely through the air gap. A supporter (39) may be positioned between the reflective sheet (60) and the diffuser plate (31), may be coupled to the reflective sheet (60), and may support the diffuser plate (31).

[0048] The optical sheet (32) may be adjacent to or in contact with the front surface of the diffuser plate (31). The optical sheet (32) may include at least one sheet. For example, the optical sheet (32) may include a plurality of sheets having different functions, and the plurality of sheets may be bonded or in close contact with each other. For example, the first optical sheet (32a) may be a diffuser sheet, and the second optical sheet (32b) may be a prism sheet. The diffuser sheet can prevent the light coming from the diffuser plate (31) from being partially concentrated, thereby making the distribution of light uniform. The prism sheet can concentrate the light coming from the diffuser sheet and provide it to the display panel (10). The number and / or position of the diffuser sheet and the prism sheet may be changed.

[0049] For example, the optical sheet (32) can change the wavelength or color of the light provided by the light source. For example, the optical sheet (32) may include a red-colored phosphor and / or a green-colored phosphor. In this case, the light source may provide blue-colored light, and the optical sheet (32) may change the light of the light source to white. The optical sheet (32) may be referred to as a QD sheet (Quantum Dot Sheet).

[0050] The frame (80) may be located at the rear of the backlight unit. The display panel (10), the side frame (20), and the backlight unit may be coupled to the frame (80). The frame (80) may support the components of the display device described above and below. For example, the frame (80) may include a metal material such as an aluminum alloy. The frame (80) may be referred to as a main frame (80), a module cover (80, module cover), or a cover bottom (80, cover bottom).

[0051] The back cover (90) can cover the rear of the frame (80) and can be attached to the frame (80). For example, the back cover (90) may be an injection-molded product made of resin. As another example, the back cover (90) may include a metal material.

[0068]

[0069] Referring to FIGS. 5 to 7, the board (P) may be a power supply board (P1), and the power supply board (P1) may be referred to as the first board (P1) or the first substrate (P1). For example, the first substrate (P1) may be a rectangular board and may have four corners (C11, C12, C13, C14). The first substrate (P1) may include a hole (13) and a slot (14).

[0070] A hole (13) can be formed by penetrating the first substrate (P1) and can be adjacent to a corner of the first substrate (P1). Each of the holes (13a, 13b, 13c) can be adjacent to each of the corners (C11, C12, C13) of the first substrate (P1). A first corner (C11) can be formed at the point where the lower side and the left side of the first substrate (P1) meet, and a first hole (13a) can be adjacent to the first corner (C11).

A fourth corner (C14) may be formed at the point where the right side and the lower side of the first substrate (P1) meet. The holes (13a, 13b, 13c) may have the same shape as each other. Alternatively, at least one of the first and second holes (13a, 13b) may have the shape of a notch-type hole formed on the left side of the first substrate (P1), like the first and second holes (33a, 33b) described later with reference to FIG. 23. Each of the holes (13a, 13b, 13c) may have a convex shape and may include a first part (131) and a second part (132). The first part (131) may be a rectangular hole having a relatively large width (W2).

The legs (154, 155) of the first clip (15a) can penetrate the first substrate (P1), and the ends of the legs (154, 155) can be soldered to the front surface of the first substrate (P1). Accordingly, the first clip (15a) can be electrically connected to the front surface of the first substrate (P1), i.e., the circuit surface.

[0076] The second clip (15b) may be adjacent to the second hole (13b), and the body (151) of the second clip (15b) may be located on the back surface of the first substrate (P1). The groove (151g) of the body (151) may be aligned with the second part (132) of the second hole (13b), and the width of the groove (151g) may be equal to or slightly different from the width (W1) of the second part (132). The arms (152, 153) of the second clip (15b) may be located in the first part (131) of the second hole (13b). The legs (154, 155) of the second clip (15b) can penetrate the first substrate (P1), and the ends of the legs (154, 155) can be soldered to the front surface of the first substrate (P1). Accordingly, the second clip (15b) can be electrically connected to the front surface of the first substrate (P1), i.e., the circuit surface.

[0077] The third clip (15c) may be adjacent to the third hole (13c), and the body (151) of the third clip (15c) may be located on the back surface of the first substrate (P1).

The arms (152, 153) of the third clip (15c) may be located in the first part (131) of the third hole (13c). The legs (154, 155) of the third clip (15c) can penetrate the first substrate (P1), and the ends of the legs (154, 155) can be soldered to the front surface of the first substrate (P1). Accordingly, the third clip (15c) can be electrically connected to the front surface of the first substrate (P1), i.e., the circuit surface.

[0078]

[0079] Referring to FIGS. 8 through 11, a first portion (80a) of the frame (80) may face a first substrate (P1, see FIG. 6).

The first recess (80Ra) may be provided in two or more (see FIG. 9) or as one (see FIG. 10). A pair of first recesses (80Ra) may include a first fixed recess (80Raa) and a first guide recess (80Rab).

[0081] The second recess (80Rb) can be recessed from the frame (80) toward the second hole (13b, see FIG. 6) of the first substrate (P1).

[0082] The third recess (80Rc) may be recessed from the frame (80) toward the third hole (13c, see FIG. 6) of the first substrate (P1).

The first contact portion (82a) may include a first part (821) and a second part (822). The first part (821) may include an inclined portion (821a) connected to the bottom part (80Raz) of the first recess (80Ra) forming the rear end of the first recess (80Ra), and a horizontal portion (821b) that curves from the inclined portion (821a) in a direction parallel to the first portion (80a). The second part (822) may extend obliquely from the horizontal portion (821b) and may be connected to the bottom part (80Raz). The width (Wa) of the first part (821) may be equal to or smaller than the width (W2, see FIG. 5) of the first part (131) of the first hole (13a). The width (Wb) of the second part (822) may be equal to or smaller than the width (W1, see FIG. 5) of the second part (132) of the first hole (13a). For example, the first contact portion (82a) may be formed by pressing from the front to the rear of the bottom part (80Raz), and in response to the pressing process, a first hole (80Rah) larger than the first contact portion (82a) may be formed in the bottom part (80Raz).

[0085] The second contact portion (82b) may protrude from the second recess (80Rb) toward the second hole (13b, see FIG. 6). The second contact portion (82b) may be referred to as the second coupling portion (82b) or the second protrusion (82b). The second contact portion (82b) may include a first part (821) and a second part (822). The first part (821) may include an inclined portion (821a) connected to the bottom part (80Rbz) of the second recess (80Rb) forming the rear end of the second recess (80Rb), and a horizontal portion (821b) that bends from the inclined portion (821a) in a direction parallel to the first part (80a).

The width (Wb) of the second part (822) may be equal to or smaller than the width (W1, see FIG. 5) of the second portion (132) of the second hole (13b). For example, the second contact portion (82b) may be formed by pressing from the front to the rear of the bottom part (80Rbz), and a second hole (80Rbh) larger than the second contact portion (82b) may be formed in the bottom part (80Rbz) in response to the pressing process.

[0086] The third contact portion (82c) may protrude from the third recess (80Rc) toward the third hole (13c, see FIG. 6). The third contact portion (82c) may be referred to as the third coupling portion (82c) or the third protrusion (82c). The third contact portion (82c) may include a first part (821) and a second part (822). The first part (821) may include an inclined portion (821a) connected to the bottom part (80Rcz) of the third recess (80Rc) which forms the rear end of the third recess (80Rc), and a horizontal portion (821b) that bends from the inclined portion (821a) in a direction parallel to the first part (80a). The second part (822) may extend obliquely from the horizontal portion (821b) and may be connected to the bottom part (80Rcz). The width (Wa) of the first part (821) may be equal to or smaller than the width (W2, see FIG. 5) of the first part (131) of the third hole (13c). The width (Wb) of the second part (822) may be equal to or smaller than the width (W1, see FIG. 5) of the second part (132) of the third hole (13c). For example, the third contact portion (82c) may be formed by pressing from the front to the rear of the bottom part (80Rcz), and a third hole (80Rch) larger than the third contact portion (82c) may be formed in the bottom part (80Rcz) in response to the pressing process.

[0087] The first to third contact portions (82a, 82b, 82c) may have the same shape as each other. The first to third contact portions (82a, 82b, 82c) may be collectively referred to as the contact portion (82). The contact portion (82) may include the metal material of the frame (80) and the recess (80R) and may have electrical conductivity. The contact portion (82) may have elasticity.

[0088] The first pin (82Pa, pin) may protrude from the first recess (80Ra) toward the first slot (14a, see FIG. 6). The diameter or width of the first pin (82Pa) may be smaller than the length of the first slot (14a), and the first pin (82Pa) may move relative to the first slot (14a). The first pin (82Pa) may be referred to as the first projection (82Pa) or the first boss (82Pa, boss).

[0089] The second pin (82Pb) may protrude from the third recess (80Rc) toward the second slot (14b, see FIG. 6). The diameter or width of the second pin (82Pb) may be smaller than the length of the second slot (14b), and the second pin (82Pb) may move relative to the second slot (14b). The second pin (82Pb) may be referred to as the second projection (82Pb) or the second boss (82Pb).

[0090] The first and second pins (82Pa, 82Pb) may have the same shape. The first and second pins (82Pa, 82Pb) may be collectively referred to as a pin (82P). The pin (82P) may have a hollow or solid cylinder shape. Either of the first and second pins (82Pa, 82Pb) may be omitted, in which case the slot of the first substrate (P1) corresponding to the omitted pin may also be omitted. A pin (82P) may be additionally formed in other recesses (80Rb, 80Rd, 80Re) in addition to the first and second pins (82Pa, 82Pb), in which case a slot may be added to the first substrate (P1) corresponding to the added pin.

[0091] The projection (82S) may protrude from the first recess (80Ra) in the same direction as the first pin (82Pa) and may be spaced apart from the first pin (82Pa) in the longitudinal direction of the first slot (14a). The distance between the first pin (82Pa) and the projection (82S) may correspond to the length of the first slot (14a). The first surface (82S1) of the projection (82S) facing the first pin (82Pa) may be inclined at an obtuse angle with respect to the bottom part (80Raz) of the first recess (80Ra). The second surface (82S2) of the projection (82S) opposite to the first surface (82S1) may intersect (perpendicular) with respect to the bottom part (80Raz). The protrusion (82S) may have a pyramid shape with a portion cut out, and a second surface (82S2) may be formed in the cut-out portion. For example, the protrusion (82S) may be formed by pressing from the front to the rear of the bottom part (80Raz), and a hole (80Rh) larger than the protrusion (82S) may be formed in the bottom part (80Raz) in response to the pressing process. The protrusion (82S) may be formed in other recesses (80Rb, 80Rc, 80Rd, 80Re) in place of or in addition to the first recess (80Ra), and in this case, a slot may be added to the first substrate (P1) in response to the protrusion (82S) that is replaced or added.

[0092]

[0093] Referring to FIGS. 12 and 8, the first substrate (P1) can be placed on the recesses (80R) of the first part (80a) of the frame (80). The front surface of the first substrate (P1) can be placed on the rear surface of the bottom parts of the recesses (80R). The first substrate (P1) placed on the recesses (80R) can be positioned parallel to the first part (80a) of the frame (80).

[0094] Each of the first to third contact portions (82a, 82b, 82c) can be inserted into the first portion (131) of each of the first to third holes (13a, 13b, 13c). Each of the first and second pins (82Pa, 82Pb) can be inserted into each of the first and second slots (14a, 14b).

[0095] The user can move the first substrate (P1) so that the first to third clips (15a, 15b, 15c) come closer to the first to third contact portions (82a, 82b, 82c). For example, the user can push the first substrate (P1) seated on the recesses (80R) to the left.

[0096]

[0097] Referring to FIGS. 13 and 14, in response to a user pushing the first substrate (P1) to the left, the first clip (15a) fixed to the first substrate (P1) can move closer to the first contact portion (82a). At this time, the first pin (82Pa) can move relative to the first slot (14a) and can guide the movement of the first substrate (P1).

[0098] Accordingly, the second part (822) of the first contact portion (82a) can be inserted into the second part (132) of the first hole (13a) and the groove (151g) of the first clip (15a), and the front surface of the horizontal portion (821b) of the first part (821) of the first contact portion (82a) can be positioned on the rear surface of the body (151) of the first clip (15a).

[0099] Furthermore, the first substrate (P1) can be moved along the first surface (82S1) of the protrusion (82S) and slightly lifted, and the protrusion (82S) can be lowered back onto the first recess (80Ra) as it is inserted into the first slot (14a). One end of the first slot (14a) can be caught on the first pin (82Pa), and the first pin (82Pa) can restrict the first substrate (P1) from moving to the left. The other end of the first slot (14a) can be caught on the second surface (82S2) of the protrusion (82S), and the protrusion (82S) can restrict the first substrate (P1) from moving to the right.

[0100]

[0101] Referring to FIGS. 15 and 16, in response to a user pushing the first substrate (P1) to the left, the second clip (15b) fixed to the first substrate (P1) can be brought closer to the second contact portion (82b).

[0102] Accordingly, the second part (822) of the second contact portion (82b) can be inserted into the second part (132) of the second hole (13b) and the groove (151g) of the second clip (15b), and the front surface of the horizontal portion (821b) of the first part (821) of the second contact portion (82b) can be positioned on the rear surface of the body (151) of the second clip (15b).

[0103]

[0104] Referring to FIGS. 17 and 18, in response to a user pushing the first substrate (P1) to the left, the third clip (15c) fixed to the first substrate (P1) can move closer to the third contact portion (82c). At this time, the second pin (82Pb) can move relative to the second slot (14b) and can guide the movement of the first substrate (P1).

[0105] Accordingly, the second part (822) of the third contact part (82c) can be inserted into the second part (132) of the third hole (13c) and the groove (151g) of the third clip (15c), and the front of the horizontal part (821b) of the first part (821) of the third contact part (82c) can be positioned on the rear surface of the body (151) of the third clip (15c).

[0106] Furthermore, one end of the second slot (14b) can be caught on the second pin (82Pb), and the second pin (82Pb) can restrict the first substrate (P1) from moving to the left.

[0107]

[0108] Referring to FIGS. 19 and 20, the ends (152a, 153a) of the arms (152, 153) of the clips (15a, 15b, 15c) can form a step that rises from the rears of the bodies (151). The horizontal portion (821b) can be fixed to the recess (80R) by the inclined portion (821a) and the second part (822), and the ends (152a, 153a) of the arms (152, 153) can be pressed forward. Accordingly, the contact between the contact portion (82) and the clip (15) can be maintained continuously and stably, and the first substrate (P1) can be electrically grounded to the frame (80) through the clip (15) and the contact portion (82).

[0109] The movement of the first substrate (P1) in the horizontal direction (i.e., left-right direction) and vertical direction (i.e., up-down direction) may be restricted by pins (82Pa, 82Pb) and protrusions (82S) inserted into slots (14a, 14b) and contact parts (82a, 82b, 82c) inserted into holes (13a, 13b, 13c). In addition, the horizontal parts (821b) of the contact parts (82a, 82b, 82c) may press the clips (15a, 15b, 15c) fixed to the first substrate (P1) forward, and the backward movement of the first substrate (P1) may be restricted by the contact parts (82a, 82b, 82c).

[0110] Accordingly, the first substrate (P1) can be detachably coupled to the first part (80a) of the frame (80). That is, the first substrate (P1) can be coupled to the first part (80a) without fastening members.

[0111] Alternatively, portions of the first substrate (P1) adjacent to the first to third corners (C11, C12, C13) may be joined to the first to third recesses (80Ra, 80Rb, 80Rc), and portions of the first substrate (P1) adjacent to the fourth corner (C14) may be joined to the fourth and fifth recesses (80Rd, 80Re) by fastening members (F1, F2) such as screws.

[0112]

[0113] Referring to FIG. 21, clips (15d, 15e) can also be fixed to a portion of the first substrate (P1) adjacent to the fourth corner (C14), in which case contact portions (82d, 82e) can be formed in the fourth and fifth recesses (80Rd, 80Re) and coupled to the clips (15d, 15e). Accordingly, the first substrate (P1) can be coupled more stably to the first portion (80a) of the frame (80).

[0114]

[0115] Referring to FIG. 22, a catch hole (82h) may be formed in the bottom part (80Raz) of the first recess (80Ra) and / or the inclined part (821a) of the first contact part (82a). The catch hole (82h) may be adjacent to the boundary between the bottom part (80Raz) and the inclined part (821a). The catch hole (82h) may be located at the boundary between the bottom part (80Raz) and the inclined part (821a). The catch hole (82h) may be a circular (elliptical) hole. Accordingly, mold stability may be improved.

[0116] The first substrate (P1) may include a protrusion (13p) protruding from one side boundary of the first hole (13a). The first hole (13a) may extend in the left-right direction, and a second part (132) may be formed by being recessed into the interior of the first substrate (P1) from a part of the right boundary of the first hole (13a). The first substrate (P1) may include a first protrusion (13ap) protruding to the right from a part of the left boundary of the first hole (13a). The first protrusion (13ap) may protrude from the center of the left boundary of the first hole (13a). The first protrusion (13ap) may be inserted into the catch hole (82h).

[0117] Likewise, the catch hole (82h) may be formed in the bottom parts of other recesses (80Rb, 80Rc, 80Rd, 80Re) and / or in the inclined parts of other contact parts (82b, 82c, 82d, 82e, see FIG. 21), and the protrusion (13p) may protrude from one side boundary of other holes (13b, 13c, see FIG. 5).

[0118] When the first substrate (P1) is pushed to the right, the protrusion (13p) catches on the catch hole (82h), thereby limiting the movement distance of the first substrate (P1) to a specific distance, and accordingly, the right side of the first substrate (P1) can be prevented from colliding with another substrate (P) or another component of the display device (1).

[0119]

[0120] Referring to FIG. 23, the board (P) may be a main board (P3), and the main board (P3) may be referred to as a second board (P3) or a second substrate (P3). For example, the second substrate (P3) may be a rectangular board and may have four corners (C31, C32, C33, C34). The second substrate (P3) may include a hole (33) and a slot (34).

[0121] A hole (33) can be formed by penetrating the second substrate (P3) and can be adjacent to a corner of the second substrate (P3). Each of the holes (33a, 33b, 33c) can be adjacent to each of the corners (C31, C32, C33) of the second substrate (P3). A first corner (C31) can be formed at the point where the lower side and the left side of the second substrate (P3) meet, and a first hole (33a) can be adjacent to the first corner (C31). A second corner (C32) can be formed at the point where the left side and the upper side of the second substrate (P3) meet, and a second hole (33b) can be adjacent to the second corner (C32). The third corner (C33) may be formed at the point where the upper side and the right side of the second substrate (P3) meet, and the third hole (33c) may be adjacent to the third corner (C33). The fourth corner (C34) may be formed at the point where the right side and the lower side of the second substrate (P3) meet. The first and second holes (33a, 33b) may be formed from the left side of the second substrate (P3) toward the inside of the second substrate (P3) and may be notch-type holes. Alternatively, at least one of the first and second holes (33a, 33b) may have a convex shape such as the third hole (33c). The third hole (33c) may include a first part (331) and a second part (332). The first part (331) may be a rectangular hole having a relatively large width (W3). The second part (332) may be a rectangular hole having a relatively small width (W4).

[0122] Additionally, the end of the hole (33) may form a chamfer portion. The portion adjacent to the left end of the first hole (33a) may form a chamfer portion (33ab, chamfer portion), and the width of the chamfer portion (33ab) may increase as it approaches the left side of the second substrate (P3). Accordingly, the second part (842) of the first contact portion (84a) described later can easily enter the first hole (33a). The portion adjacent to the left end of the second hole (33b) may form a chamfer portion (33bb, chamfer portion), and the width of the chamfer portion (33bb) may increase as it approaches the left side of the second substrate (P3). Accordingly, the second part (842) of the second contact portion (84b) described later can easily enter the second hole (33b). The portion adjacent to the first portion (331) of the second portion (332) of the third hole (33c) can form a chamfer portion (33cb), and the width of the chamfer portion (33cb) can increase as it approaches the first portion (331). Accordingly, the second part (842) of the third contact portion (84c) described later can easily enter the second portion (332).

[0123] The slot (34) can be formed by penetrating the second substrate (P3) and can be spaced apart from the hole (33). The slot (34) can be extended in the longitudinal direction of the hole (33). For example, the longitudinal direction of the hole (33) and the slot (34) can be defined in the left-right direction. The number of slots (34a, 34b) may be equal to or less than the number of holes (33a, 33b, 33c). The first slot (34a) can be adjacent to the second corner (C32) and can be extended in the left-right direction. The second slot (34b) can be adjacent to the fourth corner (C34) and can be extended in the left-right direction.

[0124] The insertion hole (34h) may be formed by penetrating the second substrate (P3) and may be spaced apart from the first slot (34a) in the longitudinal direction of the first slot (34a). The insertion hole (34h) may be located closer to the left side of the second substrate (P3) than the first slot (34a). The insertion hole (34h) may be spaced apart from the first slot (34a) in a direction intersecting the longitudinal direction of the first slot (34a).

[0125] The contact area (35) may be formed around the hole (33) and may be part of the rear surface of the second substrate (P3). The contact area (35) may be formed along the hole (33). A first contact area (35a) may be formed along the first hole (33a) around the first hole (33a). A second contact area (35b) may be formed along the second hole (33b) around the second hole (33b). A third contact area (35c) may be formed along the second part (332) around the second part (332) of the third hole (33c). The contact area (35) may be part of the circuit surface of the second substrate (P3). For example, the second substrate (P3) may be a double-sided PCB or a multi-layer PCB. The circuit surface of the second substrate (P3) on which the circuit pattern is formed may be the rear surface of the second substrate (P3) or the rear and front surfaces of the second substrate (P3). The contact area (35) may be an area where a part of the circuit surface of the second substrate (P3) is open.

[0126]

[0127] Referring to FIGS. 24 and 25, a second part (80c) of the frame (80) may face a second substrate (P3, see FIG. 23). Recesses (80F) may be formed at locations on the second part (80c) corresponding to holes (33) and slots (34) of the second substrate (P3). The recesses (80F) may include the metal material of the frame (80) and may be electrically conductive. The recesses (80F) may be formed by pressing from the front to the rear of the second part (80c) and may form a step that rises relative to the rear of the second part (80c). The heights of the recesses (80F) relative to the rear of the second part (80c) may be equal or slightly different. The recesses (80F) may be referred to as press parts (80F). The second part (80c) may also be called a flat plate (80c).

[0128] The first recess (80Fa) can be recessed from the frame (80) toward the first hole (33a, see FIG. 23) of the second substrate (P3).

[0129] The second recess (80Fb) may be recessed from the frame (80) toward the second hole (33b) of the second substrate (P3). The second recess (80Fb) may be provided in two or more (see FIG. 24) or as one. The plurality of second recesses (80Fb) may include a second fixed recess (80Fba), a second guide recess (80Fbb), and a second coupling recess (80Fbc).

[0130] The third recess (80Fc) can be recessed from the frame (80) toward the third hole (33c, see FIG. 23) of the second substrate (P3).

[0131] The fourth recess (80Fd) can be recessed from the frame (80) toward the part adjacent to the fourth corner (C34, see FIG. 23) of the second substrate (P3).

[0132] The first contact portion (84a) may protrude from the first recess (80Fa) toward the first hole (33a, see FIG. 23). The first contact portion (84a) may be referred to as the first coupling portion (84a) or the first protrusion (84a). The first contact portion (84a) may include a first part (841) and a second part (842). The first part (841) may include an inclined portion (841a) connected to the bottom part (80Faz) of the first recess (80Fa) forming the rear end of the first recess (80Fa), and a horizontal portion (841b) that bends from the inclined portion (841a) in a direction parallel to the second part (80c). The second part (842) may extend obliquely from the horizontal portion (841b) and may be connected to the bottom part (80Faz). The width of the first part (841) may be greater than the width of the first hole (33a), and the width of the second part (842) may be equal to or smaller than the width of the first hole (33a). For example, the first contact portion (84a) may be formed by pressing from the front to the rear of the bottom part (80Faz), and in response to the pressing process, a first hole (80Fah) larger than the first contact portion (84a) may be formed in the bottom part (80Faz).

[0133] The second contact portion (84b) may protrude from the second recess (80Fb) toward the second hole (33b, see FIG. 23). The second contact portion (84b) may be referred to as the second coupling portion (84b) or the second protrusion (84b). The second contact portion (84b) may include a first part (841) and a second part (842). The first part (841) may include an inclined portion (841a) connected to the bottom part (80Fbz) of the second recess (80Fb) forming the rear end of the second recess (80Fb), and a horizontal portion (841b) that bends from the inclined portion (841a) in a direction parallel to the second part (80c). The second part (842) may extend obliquely from the horizontal portion (841b) and may be connected to the bottom part (80Fbz). The width of the first part (841) may be greater than the width of the second hole (33b), and the width of the second part (842) may be equal to or smaller than the width of the second hole (33b). For example, the second contact portion (84b) may be formed by pressing from the front to the rear of the bottom part (80Fbz), and a second hole (80Fbh) larger than the second contact portion (84b) may be formed in the bottom part (80Fbz) in response to the pressing process.

[0134] The third contact portion (84c) may protrude from the third recess (80Fc) toward the third hole (33c, see FIG. 23). The third contact portion (84c) may be referred to as the third coupling portion (84c) or the third protrusion (84c). The third contact portion (84c) may include a first part (841) and a second part (842). The first part (841) may include an inclined portion (841a) connected to the bottom part (80Fcz) of the third recess (80Fc) forming the rear end of the third recess (80Fc), and a horizontal portion (841b) that bends from the inclined portion (841a) in a direction parallel to the second part (80c). The second part (842) may extend obliquely from the horizontal portion (841b) and may be connected to the bottom part (80Fcz). The width of the first part (841) may be equal to or smaller than the width (W3, see FIG. 23) of the first portion (331) of the third hole (33c). The width of the second part (842) may be equal to or smaller than the width (W4, see FIG. 23) of the second portion (332) of the third hole (33c). For example, the third contact portion (84c) may be formed by pressing from the front to the rear of the bottom part (80Fcz), and a third hole (80Fch) larger than the third contact portion (84c) may be formed in the bottom part (80Fcz) in response to the pressing process.

[0135] The first to third contact portions (84a, 84b, 84c) may have the same shape as each other. The first to third contact portions (84a, 84b, 84c) may be collectively referred to as the contact portion (84). The contact portion (84) may include the metal material of the frame (80) and the recess (80F) and may have electrical conductivity. The contact portion (84) may have elasticity.

[0136] The first pin (84Pa, pin) may protrude from the second recess (80Fb) toward the first slot (34a, see FIG. 23). The diameter or width of the first pin (84Pa) may be smaller than the length of the first slot (34a), and the first pin (84Pa) may move relative to the first slot (34a). The first pin (84Pa) may be referred to as the first projection (84Pa) or the first boss (84Pa, boss).

[0137] The second pin (84Pb) may protrude from the fourth recess (80Fd) toward the second slot (34b, see FIG. 23). The diameter or width of the second pin (84Pb) may be smaller than the length of the second slot (34b), and the second pin (84Pb) may move relative to the second slot (34b). The second pin (84Pb) may be referred to as the second projection (84Pb) or the second boss (84Pb).

[0138] The first and second pins (84Pa, 84Pb) may have the same shape. The first and second pins (84Pa, 84Pb) may be collectively referred to as a pin (84P). The pin (84P) may have a hollow or solid cylinder shape. Either of the first and second pins (84Pa, 84Pb) may be omitted, and in this case, the slot of the second substrate (P3) corresponding to the omitted pin may also be omitted. A pin (84P) may be additionally formed in other recesses (80Fa, 80Fc) in addition to the first and second pins (84Pa, 84Pb), and in this case, a slot may be added to the second substrate (P3) corresponding to the added pin.

[0139] The projection (84S) may protrude from the second recess (80Fb) in the same direction as the first pin (84Pa) and may be spaced apart from the first pin (84Pa) in the longitudinal direction of the first slot (34a). The projection (84S) may face the insertion hole (34h, see FIG. 23) of the second substrate (P3). In the longitudinal direction of the first slot (34a), the first surface (84S1) of the projection (84S) may be inclined at an obtuse angle with respect to the bottom part (80Fbz) of the second recess (80Fb). The second surface (84S2) of the projection (84S), opposite to the first surface (84S1), may intersect (perpendicular) with respect to the bottom part (80Fbz). The protrusion (84S) may have a pyramid shape with a portion cut out, and the second surface (84S2) may be formed in the cut-out portion. For example, the protrusion (84S) may be formed by pressing from the front to the rear of the bottom part (80Fbz), and a hole (80Fh) larger than the protrusion (84S) may be formed in the bottom part (80Fbz) in response to the pressing process. The protrusion (84S) may be formed in other recesses (80Fa, 80Fc, 80Fd) in place of or in addition to the second recess (80Fb), and in this case, an insertion hole may be added to the second substrate (P3) in response to the protrusion (84S) that is replaced or added.

[0140] Meanwhile, the protrusion (84S) may be inserted into a slot like the protrusion (82S, see FIG. 14) instead of the insertion hole (34h) of the second substrate (P3). Alternatively, the protrusion (82S, see FIG. 14) may be inserted into an insertion hole like the protrusion (84S) instead of the first slot (14a) of the first substrate (P1).

[0141]

[0142] Referring to FIGS. 26 to 30, the second substrate (P3) can be placed on the recesses (80F) of the second part (80c) of the frame (80). The front surface of the second substrate (P3) can be placed on the rear surface of the bottom parts of the recesses (80F). The second substrate (P3) placed on the recesses (80F) can be arranged parallel to the second part (80c) of the frame (80).

[0143] The first and second contact portions (84a, 84b) may be adjacent to the left side of the second substrate (P3), and the third contact portion (84c) may be inserted into the first portion (331) of the third hole (33c).

[0144] The user can move the second substrate (P3) so that the first to third contact areas (35a, 35b, 35c, see FIG. 23) come closer to the first to third contact portions (84a, 84b, 84c). For example, the user can push the second substrate (P3) placed on the recesses (80F) to the left.

[0145] Referring to FIG. 27, in response to a user pushing the second substrate (P3) to the left, the second part (842) of the first contact portion (84a) can be inserted into the first hole (33a), and the front surface of the horizontal portion (841b) of the first part (841) of the first contact portion (84a) can be positioned on the first contact area (35a). The bending portion (841d) can be bent backward from the end of the horizontal portion (841b) and can facilitate the movement of the first contact portion (84a) relative to the second substrate (P3). The press portion (841c) can be formed by pressing forward from the rear surface of the horizontal portion (841b) and can protrude from the front surface of the horizontal portion (841b). The press portion (841c) can come into contact with the first contact area (35a). Accordingly, the contact between the first contact portion (84a) and the first contact area (35a) can be stably maintained. That is, the second substrate (P3) can be electrically grounded to the frame (80) through the first contact area (35a) and the first contact portion (84a).

[0146] Referring to FIG. 38, in response to a user pushing the second substrate (P3) to the left, the second part (842) of the second contact portion (84b) can be inserted into the second hole (33b), and the front surface of the horizontal portion (841b) of the first part (841) of the second contact portion (84b) can be positioned on the second contact area (35b). The bending portion (841d) can be bent backward from the end of the horizontal portion (841b) and can facilitate the movement of the second contact portion (84b) relative to the second substrate (P3). The press portion (841c) can be formed by pressing forward from the rear surface of the horizontal portion (841b) and can protrude from the front surface of the horizontal portion (841b). The press portion (841c) can come into contact with the second contact area (35b). Accordingly, the contact between the second contact portion (84b) and the second contact area (35b) can be stably maintained. That is, the second substrate (P3) can be electrically grounded to the frame (80) through the second contact area (35b) and the second contact portion (84b).

[0147] Additionally, the first pin (84Pa) can move relative to the first slot (34a) and guide the movement of the second substrate (P3). The second substrate (P3) can move along the first surface (84S1) of the protrusion (84S) and be slightly lifted, and can be lowered back onto the second recess (80Fb) as the protrusion (84S) is inserted into the insertion hole (34h). One end of the first slot (34a) can be caught on the first pin (84Pa), and the first pin (84Pa) can restrict the second substrate (P3) from moving to the left. The insertion hole (34h) can be caught on the second surface (84S2) of the protrusion (84S), and the protrusion (84S) can restrict the second substrate (P3) from moving to the right.

[0148] Referring to FIG. 29, in response to a user pushing the second substrate (P3) to the left, the second part (842) of the third contact portion (84c) can be inserted into the second part (332) of the third hole (33c), and the front of the horizontal portion (841b) of the first part (841) of the third contact portion (84c) can be positioned on the third contact area (35c). The bending portion (841d) can be bent backward from the end of the horizontal portion (841b) and can facilitate the movement of the third contact portion (84c) relative to the second substrate (P3). The press portion (841c) can be formed by being pressed forward from the rear of the horizontal portion (841b) and can protrude from the front of the horizontal portion (841b). The press portion (841c) can come into contact with the third contact area (35c). Accordingly, the contact between the third contact portion (84c) and the third contact area (35c) can be stably maintained. That is, the second substrate (P3) can be electrically grounded to the frame (80) through the third contact area (35c) and the third contact portion (84c).

[0149] Referring to FIG. 30, in response to the user pushing the second substrate (P3) to the left, the second pin (84Pb) can move relative to the second slot (34b) and guide the movement of the second substrate (P3).

[0150] The movement of the second substrate (P3) in the horizontal direction (i.e., left-right direction) and vertical direction (i.e., up-down direction) may be restricted by pins (84Pa, 84Pb) inserted into slots (34a, 34b), a projection (84S) inserted into an insertion hole (34h), and contact portions (84a, 84b, 84c) inserted into holes (33a, 33b, 33c). Additionally, the press portions (841c) of the contact portions (84a, 84b, 84c) may press the contact areas (35a, 35b, 35c) of the second substrate (P3) forward, and the backward movement of the second substrate (P3) may be restricted by the contact portions (84a, 84b, 84c).

[0151] Accordingly, the second substrate (P3) can be detachably coupled to the second part (80c) of the frame (80). That is, the second substrate (P3) can be coupled to the second part (80c) without fastening members.

[0152] Alternatively, parts of the second substrate (P3) adjacent to the first to third corners (C31, C32, C33) may be joined to the first to third recesses (80Fa, 80Fb, 80Fc), and parts of the second substrate (P3) adjacent to the fourth corner (C34) may be joined to the fourth recess (80Fd) by fastening members (F3, F4), such as screws.

[0153]

[0154] Referring to FIG. 31, the fourth contact portion (84d) can be formed in the fourth recess (80Fd) and can be coupled to the hole (33d) of the second substrate (P3) adjacent to the fourth corner (C34). Accordingly, the second substrate (P3) can be coupled more stably to the second part (80c) of the frame (80).

[0155]

[0193] Each of the fourth, fifth, and seventh contact portions (86d, 86e, 86g) may have the same shape as the third contact portion (86c), and each of the fourth, fifth, and seventh holes (43d, 43e, 43g) may have the same shape as the third hole (43c). Specifically, the second substrate (P3) may include protrusions (43p) protruding from one side boundary of each of the fourth, fifth, and seventh holes (43d, 43e, 43g), and each of the protrusions (43p) may be inserted into a catch hole (861h) formed in each of the fourth, fifth, and seventh contact portions (86d, 86e, 86g).

[0194] Each of the first, second, and sixth contact portions (86a, 86b, 86f) may have the same shape as the third contact portion (86c).

[0195] When the second substrate (P3) is pushed to the right, the protrusion (43p) catches on the catch hole (861h), thereby limiting the movement distance of the second substrate (P3) to a specific distance, and accordingly, the right side of the second substrate (P3) can be prevented from colliding with the stand (500, see FIG. 34) or the supporter (530, see FIG. 34).

[0196] The clip (17) may include a body (171), arms (172, 173), and legs (174, 175). The clip (17) may be electrically conductive. The clip (17) may be made of a metal material. The clip (17) may be elastic. The body (171) may have a rectangular, flat plate shape. The first arm (172) and the second arm (173) may protrude from one side of the body (171) and may be spaced apart from each other along said side. A groove (171g) may be formed between the first arm (172) and the second arm (173). The arms (172, 173) may extend along the length of the hole (43), and a portion of each arm may overlap with the first portion (431) of the hole (43). A portion of the first arm (172) may be bent to form a first bending portion (172a), and a portion of the second arm (173) may be bent to form a second bending portion (173a). The first bending portion (172a) may be located at the rearmost end of the first arm (172) and may be referred to as one end (172a) of the first arm. The second bending portion (173a) may be located at the rearmost end of the second arm (173) and may be referred to as one end (173a) of the second arm.

[0197] The first bending portion (172a) can form a step that rises from the rear of the body (171). The second bending portion (173a) can form a step that rises from the rear of the body (151). The first leg (174) and the second leg (175) can be bent forward from the other side of the body (171) and can be spaced apart from each other.

[0198] Specifically, the first arm (172) and the second arm (173) may extend to the left from the left side of the body (171), and the second arm (173) may be spaced downward from the first arm (172). The first leg (174) and the second leg (175) may bend forward from the right side of the body (171), and the second leg (175) may be spaced downward from the first leg (174).

[0199]

[0200] Referring to FIG. 37, a third part (80e) of the frame (80) may face a third substrate (P4, see FIG. 33). Recesses (80G) may be formed at locations on the third part (80e) corresponding to holes (43) and slots (44) of the second substrate (P3). The recesses (80G) may include the metal material of the frame (80) and may be electrically conductive. The recesses (80G) may be formed by pressing from the front to the rear of the third part (80e) and may form a step that rises relative to the rear of the third part (80e). The heights of the recesses (80G) relative to the rear of the third part (80e) may be equal or slightly different. The third part (80e) may also be referred to as a flat part (80e). The recessed portion (80G) may be referred to as the press portion (80G). The recessed portion (80G) may include a bottom part (80Gz) that is spaced rearward from the third portion (80e), and the contact portion (86) may protrude rearward from the bottom part (80Gz). A hole (80Gh) may be formed in the bottom part (80Gz), and the hole (80Gh) may be formed at the rear of the contact portion (86). For example, the contact portion (86) may be formed by pressing from the front of the bottom part (80Gz) to the rear, and a hole (80Gh) larger than the contact portion (86) may be formed in the bottom part (80Gz) in response to the pressing process.

[0201] The recess (80G) may include the first to seventh recesses (80G), and each of the first to seventh contact portions (86) may protrude backward from each of the first to seventh recesses (80G).

[0202] Each of the first to seventh recesses (80G) can be recessed from the frame (80) toward the first to seventh holes (43a, 43b, 43c, 43d, 43e, 43f, 43g, see FIG. 32) of the second substrate (P3), and each of the first to seventh contact portions (86a, 86b, 86c, 86d, 86e, 86f, 86g, see FIG. 33) can be recessed from each of the first to seventh recesses (80G) toward each of the first to seventh holes (43a, 43b, 43c, 43d, 43e, 43f, 43g, see FIG. 32) of the second substrate (P3).

[0203]

[0204] Referring to FIG. 33 and FIG. 38 together, the clip (17) may be adjacent to the hole (43), and the body (171) may be located on the rear surface of the second substrate (P3). For example, the second substrate (P3) may be a single-sided PCB. The single-sided PCB may be referred to as a 1-layer PCB or single-layer PCB. The circuit surface of the second substrate (P3) on which the circuit pattern is formed may be the front surface of the second substrate (P3).

[0205] The groove (171g) of the clip (17) can be aligned with the second part (432) of the hole (43), and the width (Wg) of the groove (171g) may be equal to or slightly different from the width (W6) of the second part (432). The arms (172, 173) of the clip (17) may be located in the first part (431) of the hole (43). The legs (174, 175) of the clip (17) may penetrate the second substrate (P3), and the ends of the legs (174, 175) may be soldered to the front surface of the second substrate (P3). Accordingly, the clip (17) may be electrically connected to the front surface, i.e., the circuit surface, of the second substrate (P3).

[0206] Specifically, each of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) may be adjacent to each of the first to seventh holes (43a, 43b, 43c, 43d, 43e, 43f, 43g), and the body (171) of each of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) may be located on the rear surface of the second substrate (P3). Each groove (171g) of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) can be aligned with the second part (432) of each of the first to seventh holes (43a, 43b, 43c, 43d, 43e, 43f, 43g), and the width (Wg) of the groove (171g) may be equal to or slightly different from the width (W6) of the second part (432). The arms (172, 173) of each of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) may be located in the first part (431) of each of the first to seventh holes (43a, 43b, 43c, 43d, 43e, 43f, 43g). The legs (174, 175) of each of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) may penetrate the second substrate (P3), and the ends of the legs (174, 175) may be soldered to the front surface of the second substrate (P3). Accordingly, each of the first to seventh clips (17a, 17b, 17c, 17d, 17e, 17f, 17g) can be electrically connected to the front surface, i.e., the circuit surface, of the second substrate (P3).

[0207] Alternatively, the second substrate (P3) may be a double-sided PCB or a multi-layer PCB. The circuit surface of the second substrate (P3) on which the circuit pattern is formed may be the rear surface of the second substrate (P3) or the rear and front surfaces of the second substrate (P3). The ends of the legs (174, 175) of the clip (17) may be soldered to the front or rear surface of the second substrate (P3). Accordingly, the clip (17) may be electrically connected to the circuit surface of the second substrate (P3).

[0208] The catch hole (861h) may be circular, with a cross-section viewed from the front and rear directions having a first diameter (D1). The width (D2) of the protrusion (43p) may be smaller than the first diameter (D1), and accordingly, the protrusion (43p) may be inserted into the catch hole (861h).

[0209] Specifically, when the second substrate (P3) is pushed to the right, the arms (172, 173) of the clip (17) can be positioned to the right of the horizontal portion (861b) of the protrusion (86), and the second part (862) can be separated from the second portion (432) of the hole (43) and positioned in the first portion (431). The protrusion (43p) can be inserted into the catch hole (861h) to prevent the second substrate (P3) from being pushed to the right by more than a certain distance.

[0210]

[0211] Referring to FIG. 39, the second substrate (P3) may be located on the bottom part (80Gz) of the recess (80G), and the thickness (h1) of the second substrate (P3) may be smaller than the height (h3) from the bottom part (80Gz) to the horizontal part (861b) of the contact part (86). The catch hole (861h) may be located across the inclined part (861a, see FIG. 36) and the bottom part (80Gz), and the cross-section viewed from the front and rear directions may be circular. The rightmost boundary (861hr) of the catch hole (861h) may be located at the point where the horizontal part (861b) and the inclined part (861a) meet. As the catch hole (861h) is formed in the inclined portion (861a, see FIG. 36), the far right boundary (861hr) of the catch hole (861h) may be a boundary located at the rearmost end of the catch hole (861h), and the far right boundary (861hr) may also be referred to as the rearmost boundary (861hr). The far right boundary (861hr) may include a first far right boundary (861hr1) formed on the front of the first part (861) and a second far right boundary (861hr2) formed on the rear of the first part (861). The distance between the first far right boundary (861hr1) and the second far right boundary (861hr2) may be equal to the thickness of the first part (861). For example, the distance between the first rightmost boundary (861hr1) and the second rightmost boundary (861hr2) is 0.1 mm or more and may be less than 0.5 mm.

[0212] The height (h2) from the rear of the bottom part (80Gz) to the first rightmost boundary (861hr1) of the catch hole (861h) may be greater than the thickness (h1) of the second substrate (P3). The protrusion length (L1) of the protrusion (43p) may be smaller than the width (D2, see FIG. 38) of the protrusion (43p). The height (h3) from the rear of the bottom part (80Gz) to the horizontal part (861b) may be greater than the thickness (h1) of the second substrate (P3). The protrusion length (L1) of the protrusion (43p) may be smaller than or equal to the thickness (h1) of the second substrate (P3).

[0213] For example, the thickness (h1) of the second substrate (P3) may be greater than or equal to 1.2 mm and less than 1.8 mm. The height (h2) from the rear of the bottom part (80Gz) to the first far right boundary (861hr1) of the catch hole (861h) may be greater than or equal to 1.8 mm and less than 2.1 mm. The height (h3) from the rear of the bottom part (80Gz) to the rear of the horizontal part (861b) may be greater than or equal to 2.0 mm and less than 2.4 mm. The protrusion length (L1) of the protrusion (43p) may be greater than or equal to 1.0 mm and less than 2.0 mm. The width (D2, see FIG. 38) of the protrusion (43p) may be greater than or equal to 2 mm and less than 3.5 mm. The catch hole (861h) may be circular, with a cross-section viewed from the front and rear directions having a first diameter (D1, see FIG. 38), and the first diameter (D1) may be greater than or equal to 3.5 mm and less than 5.5 mm.

[0214] When the second substrate (P3) is pushed to the right from the frame (80), the left boundary (4311, see FIG. 36) of the hole (43) may come into contact with the inclined portion (861a, see FIG. 36), and the second substrate (P3) may be pushed backward along the inclined portion (861a). At this time, the protrusion (43p) may be inserted into the catch hole (861h), and the rear surface of the second substrate (P3) may be positioned in front of the front surface of the horizontal portion (861b) to prevent the second substrate (P3) from being pushed further backward.

[0215] In another embodiment, the second substrate (P3) may have elasticity, and when the second substrate (P3) is slightly lifted backward along the inclined portion (861a, see FIG. 36), the second substrate (P3) may be bent so that the protrusion (43p) faces forward to the right, and accordingly, the protrusion (43p) may be caught in the catch hole (861h).
