The magnets (11M) arranged on each of the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) may be provided in multiple numbers. A plurality of magnets (11M) arranged in each of the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) may be arranged in rows and columns. A plurality of magnets (11M) arranged in each of the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) may be aligned with a plurality of magnets (21M, see FIG. 2) arranged in each of the plurality of regions (21Fa, 21Fb, 21Fc, 21Fd, 21Fe, 21Ff) of the front panel (21F). For example, a plurality of first magnets (11Ma) arranged in the first display panel (11a) may face a plurality of first magnets (21Ma) arranged in the first region (21Fa). The description of the first magnets (11Ma) can be equally applied to the magnets (11M) arranged in each of the second to sixth display panels (11b, 11c, 11d, 11e, 11f).

[0070] The magnet (11M) of the display panel (11) may be referred to as a first coupling member (11M), and the magnet (21M) of the frame (20) may be referred to as a second coupling member (21M). As described above, both the first coupling member (11M) and the second coupling member (21M) may be magnets, and a magnetic attraction may act between the first coupling member (11M) and the second coupling member (21M).

[0072] Alternatively, the second coupling member (21M) may be a magnet, and the first coupling member (11M) may be a magnetic substance such as iron (Fe). The first coupling member (11M) may be magnetically coupled to the second coupling member (21M).

[0073] That is, both the first coupling member (11M) and the second coupling member (21M) may be magnets and may be coupled to each other by magnetic force (magnetic attraction). Alternatively, either the first coupling member (11M) or the second coupling member (21M) may be a magnet, and the other may be a magnetic material coupled to the magnet by magnetic force (magnetic attraction).

[0074]

[0075] Referring to FIG. 8, a guide protrusion (120) may protrude rearwardly from a substrate (110). The guide protrusion (120) may be formed on or coupled to the substrate (110). The guide protrusion (120) may be arranged at the center of the substrate (110) of each of a plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f, see FIG. 1) (see FIG. 7).

For example, the cross-section of the neck (122) may be rectangular or square (see FIG. 7), or trapezoidal (see FIG. 8). Meanwhile, when the body (121) is omitted, the neck (122) may be formed on or bonded to the rear surface of the substrate (110).

[0079] The head (123) may be formed at the end (i.e., rear end) of the neck (122). The head (123) may have a spherical or ball-shaped shape. The diameter (D3) of the head (123) may be larger than the diameter or width of the end of the neck (122). The shape of the head (123) may correspond to the insertion space (222S) of the holder (220) described above with reference to FIG. 5. The head (123) may be inserted into the insertion space (222S). That is, the ribs (222) forming the insertion space (222S) may be arranged along the side of the head (123).

[0080]

[0081] Referring to FIG. 9, a guide protrusion (120') may protrude rearwardly from a substrate (110). The guide protrusion (120') may be formed on or coupled to the substrate (110). The guide protrusion (120') may be arranged at the center portion (see FIG. 7) of each of the substrates (110) of a plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f, see FIG. 1). Alternatively, a plurality of guide protrusions (120') may be provided on each substrate (110).

[0082] The guide protrusion (120') may include a body (121), a neck (122'), and a head (123'). The guide protrusion (120') may be referred to as a guide part (120').

[0083] The body (121') may be formed on the back surface of the substrate (110) or may be coupled to the substrate (110). The body (121') may form a step that increases rearward from the back surface of the substrate (110). The body (121') may have a rectangular plate shape. Alternatively, the body (121') may be omitted.

[0084] The neck (122') may protrude rearwardly from the body (121). The neck (122') may be referred to as a pillar (122'). The neck (122') may have the shape of a circular pillar or an angular pillar. For example, the cross-section of the neck (122') may be rectangular. Meanwhile, when the body (121) is omitted, the neck (122') may be formed on or bonded to the rear surface of the substrate (110).

[0085] The head (123') may be formed at the end (i.e., the rear end) of the neck (122'). The head (123') may have a block shape with an overall rectangular cross-section. The surface of the head (123') may be rounded. The height (H30') of the head (123') may be greater than the height (H20') of the neck (122').

The shape of the head (123') may correspond to the insertion space (222S') of the holder (220') described above with reference to FIG. 6. The head (123') can be inserted into the insertion space (222S'). That is, the ribs (222') forming the insertion space (222S') can be arranged along the side of the head (123').

[0086]

[0087] Referring to FIG. 10, a connector (112) may be coupled to the rear of a substrate (110). The connector (112) may be disposed on a plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f, see FIG. 1). The connector (112) may be referred to as a panel-side connector (112) or a front connector (112). Data and / or signals may be provided to the substrate (110) through the connector (112), and light sources (110L, see FIG. 1) on the substrate (110) may be driven by the signals and / or data.

[0088] The connector (112) may protrude rearwardly from the rear surface of the substrate (110). The connector (112) may be spaced apart from a plurality of magnets (11M) and guide protrusions (120, see FIG. 8; 120', see FIG. 9) (see FIG. 7). With respect to the rear surface of the substrate (110), the heights (i.e., protrusion heights) of the magnets (11M), the guide protrusions (120, see FIG. 8; 120', see FIG. 9), and the connector (112) may be different from each other. The height (Ha) of the magnets (11M) may be smaller than the height (Hc) of the connector (112). The height (Hb) of the guide protrusions (120, see FIG. 8; 120', see FIG. 9) may be larger than the height (Hc) of the connector (112). That is, the guide protrusion (120) can protrude further rearward from the rear surface of the substrate (110) than the magnet (11M) and the connector (112).

[0089]

[0090] Referring to FIGS. 11 and 12, a connector (J) may protrude forward from the front surface of the board (C). The connector (J) may be arranged in each of a plurality of regions (Ca, Cb, Cc, Cd, Ce, Cf, see FIG. 1) of the board (C). The connector (J) may be referred to as a board-side connector (J) or a rear connector (J). A first connector (Ja) may be arranged in a first region (Ca) and may correspond to a first display panel (11a) (see FIG. 1). A second connector (Jb) may be arranged in a second region (Cb) and may correspond to a second display panel (11b) (see FIG. 1). A third connector (Jc) may be arranged in a third region (Cc) and may correspond to a third display panel (11c) (see FIG. 1). The fourth connector (Jd) may be arranged in the fourth area (Cd) and may correspond to the fourth display panel (11d) (see FIG. 1). The fifth connector (Je) may be arranged in the fifth area (Ce) and may correspond to the fifth display panel (11e) (see FIG. 1). The sixth connector (Jf) may be arranged in the sixth area (Cf) and may correspond to the sixth display panel (11f) (see FIG. 1).

[0091] The guide protrusion (120) of the display panel (11) can be directed toward the holder (220) of the frame (20). The head (123) of the guide protrusion (120) can be inserted into the insertion space (222S) inside the ribs (222) of the holder (220). The diameter (D3) of the head (123) can be larger than the diameter (D1) of the insertion space (222S) formed by the front ends of the ribs (222). That is, as the head (123) is inserted into the insertion space (222S), the ribs (222) can be spread by the head (123). In other words, the head (123) inserted into the insertion space (222S) can be caught by the ribs (222) due to the elasticity of the ribs (222) that are trying to return to their original state, and the detachment of the guide protrusion (120) can be limited to a certain level. In particular, as the thickness (t1) of the front end of the ribs (222) is formed relatively thin, the flexible characteristics of the ribs (222) can be improved.

[0092] Likewise, referring to FIGS. 6 and 9, the guide protrusion (120') of the display panel (11) may be directed toward the holder (220') of the frame (20). The head (123') of the guide protrusion (120') may be inserted into the insertion space (222S') inside the ribs (222') of the holder (220'). The width (W30') and the height (H30') of the head (123') may be greater than the width (W1') and the height (H1') of the insertion space (222S') formed by the front ends of the ribs (222'). That is, as the head (123') is inserted into the insertion space (222S'), the ribs (222') may be spread apart by the head (123'). In other words, the head (123') inserted into the insertion space (222S') can be caught by the ribs (222') due to the elasticity of the ribs (222') that are trying to return to their original state, and the detachment of the guide protrusion (120') can be limited to a certain level. In particular, as the thickness (t1') of the front end of the ribs (222') is formed relatively thin, the flexible characteristics of the ribs (222') can be improved.

[0093] When the guide protrusion (120, see Figs. 11 and 12; 120', see Fig. 9) is inserted into the holder (220, see Figs. 11 and 12; 220', see Fig. 6), the horizontal movement of the display panel (11) can be limited, and the display panel (11) can be guided to the correct position. Here, the horizontal movement can be a movement on the xy plane (i.e., x-axis and y-axis movement). The height (Hb) at which the guide protrusion (120; 120') protrudes from the rear surface of the substrate (110) can be greater than the height (Hc) at which the connector (112) protrudes from the rear surface of the substrate (110). In this case, before the connector (112) of the display panel (11) is coupled to the connector (J) of the board (C), the guide protrusion (120; 120') can be inserted into the holder (220; 220').

[0094] At this time, the distance (Daa, see Fig. 7) between the guide protrusion (120; 120') and the connector (112) may be equal to the distance (Da, see Fig. 2) between the holder (220; 220') and the connector (J).

[0095] That is, when the guide protrusion (120, see FIGS. 11 and 12; 120', see FIG. 9) is inserted into the holder (220, see FIGS. 11 and 12; 220', see FIG. 6), the first coupling member (11M) of the display panel (11) can be aligned with the second coupling member (21M) of the frame (20) and can be magnetically coupled to the second coupling member (21M). In addition, when the guide protrusion (120, see FIGS. 11 and 12; 120', see FIG. 9) is inserted into the holder (220, see FIGS. 11 and 12; 220', see FIG. 6), the connector (112) of the display panel (11) can be aligned with the connector (J) of the board (C) and can be coupled to the connector (J) and electrically connected.

[0096] Accordingly, the combination of the guide protrusion (120, see Figs. 11 and 12; 120', see Fig. 9) and the holder (220, see Figs. 11 and 12; 220', see Fig. 6) can guide not only the combination of the first and second coupling members (11M, 21M) but also the combination of the connectors (112, J). The protrusion (213) of the frame (20) adjacent to the second coupling member (21M) and the second coupling member (21M) can be positioned forward of the holder (220; 220'). Even when the coupling of the connectors (112, J) is completed, the head (123; 123') of the guide projection (120, see FIGS. 11 and 12; 120', see FIG. 9) can be spaced apart from the body (221) of the holder (220, see FIGS. 11 and 12; 220', see FIG. 6) (see the separation distance (De) of FIG. 12), so that the guide projection (120; 120') and the holder (220; 220') can guide the coupling of the connectors (112, J) to the end. In addition, when the connectors (112, J) are coupled to each other, the first and second coupling members (11M, 21M) can be adjacent to each other and magnetically coupled to each other. For example, when the connectors (112, J) are coupled to each other, the first and second coupling members (11M, 21M) can come into contact with each other.

[0097] A user can easily and quickly couple each of a plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) to each of a plurality of areas (21Fa, 21Fb, 21Fc, 21Fd, 21Fe, 21Ff) of a frame (20). In addition, poor coupling or connection of connectors (112, J) due to misalignment can be minimized, and damage to connectors (112, J) can be minimized. The board (C) can provide data and / or signals to each of a plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) through connectors (112, J), and the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) can be driven by the data and / or signals.

[0098] Meanwhile, a protruding portion (213) may protrude from the front panel (21F) toward the display panel (11). The protruding portion (213) may have a cylindrical shape. The protruding portion (213) may be adjacent to the second connecting member (21M) of the frame (20). Each of the plurality of protruding portions (213) may be adjacent to each of the second connecting members (21M). The front end of the protruding portion (213) may be positioned forward of the front end of the holder (220). The display panel (11) may be restricted from moving backward by contacting the protruding portion (213).

[0099]

[0100] Referring to Fig. 13, a hook (223) may be formed on the inner side of each of the ribs (222) adjacent to the front end of the ribs (222). The hook (223) may be a protrusion formed on the inner side of each of the ribs (222). The head (123) of the guide protrusion (120) inserted into the insertion space (222S) inside the ribs (222) may be caught on the hook (223), thereby increasing the bonding force between the guide protrusion (120) and the holder (220).

[0101] Likewise, a hook may be formed on the inside of each of the ribs (222', see FIG. 6) adjacent to the front end of the ribs (222'), and the head (123', see FIG. 9) of the guide projection (120') inserted into the insertion space (222S) inside the ribs (222) may be caught on the hook.

[0102]

[0103] Referring again to FIGS. 1 and 2, each of the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) may be coupled to a holder (220) of each of the plurality of regions (21Fa, 21Fb, 21Fc, 21Fd, 21Fe, 21Ff) of the frame (20). Each of the plurality of display panels (11a, 11b, 11c, 11d, 11e, 11f) may be electrically connected to each of the plurality of connectors (Ja, Jb, Jc, Jd, Je, Jf) of the board (C). A specific holder (220) and a specific connector (J) may be coupled or connected to a specific display panel (11).

[0104] For example, the first display panel (11a) can be coupled to the holder (220) of the first area (21Fa), and the connector (112, see FIG. 7) of the first display panel (11a) can be electrically connected to the first connector (Ja).

[0105] For example, the second display panel (11b) can be coupled to the holder (220) of the second area (21Fb), and the connector (112) of the second display panel (11b) can be electrically connected to the second connector (Jb).

[0106] The distance (Da) between the holder (220) of the first region (21Fa) and the first connector (Ja) may be the same as the distance (Db) between the holder (220) of the second region (21Fb) and the second connector (Jb). The distances (Da, Db) may be referred to as linear distances (Da, Db) or horizontal distances (Da, Db). In this case, the second display panel (11b) may be a panel similar to the first display panel (11a), and may be mounted on the second region (21Fb) in an inverted state by 180 degrees compared to the first display panel (11a).

[0107] Accordingly, by unifying the distance between each holder (220) and each connector (J), the display device (1) can be equipped with display panels (11a, 11b, 11c, 11d, 11e, 11f) that are identical to each other. In other words, the types of the display panels (11a, 11b, 11c, 11d, 11e, 11f) can be specified as one.
