[0047] In this document, some exemplary embodiments of the present disclosure will be described with reference to the accompanying drawings.

[0048] Figure 1 This is a plan view illustrating a splicing display device including a display device according to an embodiment of the present disclosure.

[0049] Reference Figure 1 A video wall display device TD may include multiple unit display devices UD. The video wall display device TD may be a large-size display device in which the unit display devices UD are arranged adjacent to each other (e.g., spliced). For example, the video wall display device TD may include unit display devices UD arranged in a matrix of four rows by four columns. For example, when each of the unit display devices UD has a screen size of approximately 36.5 inches diagonally, the video wall display device TD may have a screen size of approximately 146 inches diagonally. However, embodiments of this disclosure are not limited to any particular number or size of unit display devices UD.

[0050] The display quality of the screen of a video wall display device TD can be determined based on the arrangement of adjacent unit display devices UD. To achieve a natural image on the screen of the video wall display device TD, precise alignment techniques are required for the adjacent unit display devices UD. A display device according to one or more embodiments of this disclosure may include a position adjustment device for display modules (hereinafter referred to as a display module position adjustment device) to precisely adjust the position of the display modules and to align them with another adjacent display device. In this disclosure, "display device" is used in the same sense as "unit display device".

[0051] Figure 2 This is an exploded perspective view illustrating a display device according to an embodiment of the present disclosure. The display device UD of the present disclosure may include a display module DM. Although not shown in detail, the display module DM may include a display panel, an input sensor, and a cover panel.

[0052] According to the implementation method, the display device UD can be combined with a splicing display device TD (see reference). Figure 1A unit display device UD corresponds to a display module DM. The display device UD may include a display module DM and a cabinet CB. That is, the display module DM can be connected to the cabinet CB to form a unit display device UD. When the display module DM is connected to the cabinet CB, the position of the display module DM can be adjusted by a display module position adjustment device.

[0053] Reference Figure 2 Assembly components FP can be disposed on the rear surface of the display module DM. Assembly components FP can be used to secure the display module DM to the cabinet CB. Multiple assembly components FP can be provided. According to an embodiment, at least two assembly components FP can be provided. Although not shown in the figures, when two assembly components FP are provided, they can be disposed diagonally at the edges of the display module DM, spaced apart from each other. Figure 2 The diagram shows four assembly components FP. The assembly components FP can be attached to the rear surface of the display module DM and spaced apart from each other.

[0054] In one embodiment, the shielding member SH may also be disposed on the rear surface of the display module DM. The shielding member SH can be used to protect the circuit board included in the display module DM.

[0055] In an implementation, the opening AA may be defined as extending through the cabinet CB. The opening AA may be configured to expose a portion of the display module position adjustment device, described later, to the outside. For example, the controller of the display module position adjustment device may be exposed to the outside through the opening AA of the cabinet CB. This will be described in more detail later.

[0056] Figure 3 This is a view showing a display module position adjustment device connected to a display device according to an embodiment of the present disclosure. Figure 3 It is shown Figure 2 Adjust the device's view by positioning the display module in area XX'. Figure 4A and Figure 4B This is a perspective view showing a display module position adjustment device according to an embodiment of the present disclosure. Figure 4B It is along Figure 4A The three-dimensional sectional view taken from the second direction DR2.

[0057] Reference Figure 3The display module position adjustment device 1000 can be connected to the display module DM. In one embodiment, the display module position adjustment device 1000 can be connected to an assembly member FP disposed on the rear surface of the display module DM. The display module position adjustment device 1000 can be connected to the assembly member FP of the display module DM to slightly move the display module DM in a first direction DR1, a second direction DR2, and a third direction DR3. In this embodiment, the first direction DR1 can correspond to the thickness direction of the display module DM, and each of the second direction DR2 and the third direction DR3 can be substantially perpendicular to the first direction DR1. The second direction DR2 and the third direction DR3 can be substantially perpendicular to each other in the same plane. In the coordinate system, the first direction DR1 can correspond to the z-axis direction, the second direction DR2 can correspond to the x-axis direction, and the third direction DR3 can correspond to the y-axis direction.

[0058] The display module position adjustment device 1000 can slightly move the display module DM connected to it in the first direction DR1, the second direction DR2 and the third direction DR3, and thus adjust the position of the display module DM so that the display module DM is aligned with other adjacent display modules.

[0059] Reference Figure 3 , Figure 4A and Figure 4B The display module position adjustment device 1000 may include a first direction control module 100, a second direction control module 200 and a third direction control module 300.

[0060] The first direction control module 100 can control the position of the display module DM in the first direction DR1. That is, the first direction control module 100 can make the display module DM move closer to or further away from the cabinet CB (see reference). Figure 2 The display module DM moves in the direction of DR1. The second direction control module 200 can control the position of the display module DM in the second direction DR2. For example, the second direction control module 200 can move the display module DM left or right. The third direction control module 300 can control the position of the display module DM in the third direction DR3. For example, the third direction control module 300 can move the display module DM up or down. The display module position adjustment device 1000 can slightly move the display module DM in the first direction DR1, the second direction DR2, and the third direction DR3 to precisely adjust the relative position of the display module DM with respect to other display modules.

[0061] Reference Figure 4A and Figure 4B The first direction control module 100 may include a first stage 110 and a connecting screw 120.

[0062] The first stage 110 may be provided with a fixing slot 111, to which the display module DM is fixed. The fixing slot 111 may be defined in the upper surface of the first stage 110. The fixing slot 111 may be defined in a first surface of the first stage 110 facing the display module DM. More specifically, an assembly member FP attached to the display module DM may be fixed to the fixing slot 111.

[0063] A connecting screw 120 may protrude from a first stage 110 to a second stage 210. The connecting screw 120 may be disposed on a second surface of the first stage 110 opposite to the first surface, and a retaining groove 111 is defined in the first surface of the first stage 110. The connecting screw 120 may include a plurality of first thread crests. The plurality of first thread crests may engage with a plurality of first thread roots of the second stage 210. In this disclosure, thread crests and thread roots are used to distinguish them from each other for ease of illustration, but they should not be particularly limited thereto or thereby restricted. For example, it may be stated that the thread roots of the connecting screw 120 engage with the thread crests of the second stage 210.

[0064] That is, the first stage 110 can be rotatably connected to the second stage 210 via the connecting screw 120. When the connecting screw 120 is tightened, the first stage 110 can move in the first direction DR1 to approach the second stage 210. When the connecting screw 120 is loosened, the first stage 110 can move in the first direction DR1 to move away from the second stage 210. In other words, the rotational movement of the connecting screw 120 can cause linear movement of the first stage 110 in the first direction DR1.

[0065] In one embodiment, a plurality of protrusions and recesses 112 may be provided on a third surface connecting the first surface and the second surface of the first stage 110. The first surface, the second surface, and the third surface may correspond to the upper surface, the lower surface, and the side surface of the first stage 110, respectively. The protrusions and recesses 112 may correspond to the controller of the first direction control module 100. The user may rotate the first stage 110 by attaching an adjustment tool to the protrusions and recesses 112. As the first stage 110 rotates, the connecting screws 120 are loosened or tightened from the second stage 210, and the first stage 110 may move in the first direction DR1.

[0066] The second direction control module 200 may include a second stage 210 and a first controller 220. The second stage 210 can be moved in the second direction DR2 via the first controller 220. That is, the user can operate the first controller 220 to allow the second stage 210 to move in the second direction DR2, and thus adjust the position of the display module DM connected to it in the second direction DR2.

[0067] More specifically, the second stage 210 can be moved in the second direction DR2 via the first controller 220, and in this case, the first stage 110 connected to the second stage 210 can also be moved in the second direction DR2. Therefore, the display module DM fixed to the first stage 110 can be moved in the second direction DR2.

[0068] The first controller 220 can be rotatably connected to the second stage 210 and the third stage 310. That is, the first controller 220 can rotate by user operation while being connected to the second stage 210 and the third stage 310. The first controller 220 can rotate while moving along the second direction DR2. The first controller 220 can push or pull the second stage 210 connected to it in the second direction DR2 while moving along the second direction DR2. That is, the rotational movement of the first controller 220 can cause linear movement of the second stage 210 in the second direction DR2.

[0069] The third-direction control module 300 may include a third stage 310 and a second controller 320.

[0070] The third stage 310 can be moved to DR3 by a third party. The third stage 310 can be connected to the first controller 220, and the first controller 220 can be connected to the second stage 210. That is, the third stage 310 can be connected to the second stage 210 through the first controller 220.

[0071] The second stage 210 can be connected to the first stage 110. Therefore, the third stage 310 can be connected to the first stage 110. The display module DM can be fixed to the first stage 110. When the third stage 310 moves on the third-party direction DR3, the first stage 110 can also move on the third-party direction DR3. When the first stage 110 moves on the third-party direction DR3, the position of the display module DM fixed to it can move on the third-party direction DR3. Therefore, when the third stage 310 moves on the third-party direction DR3, the position of the display module DM on the third-party direction DR3 can be adjusted.

[0072] The second controller 320 can control the third stage 310, causing the third stage 310 to move on the third-party axis DR3. The second controller 320 can be rotatably coupled to the third stage 310. The second controller 320 can be rotated by user operation. The third stage 310 can move on the third-party axis DR3 by rotating the second controller 320. This will be described in more detail later.

[0073] The display module position adjustment device 1000 may further include a first housing CS1, a second housing CS2, and a third housing CS3. The first housing CS1, the second housing CS2, and the third housing CS3 may be connected to each other to form the housing of the display module position adjustment device 1000. The housing of the display module position adjustment device 1000 may cover the second stage 210 and the third stage 310, and may expose the first stage 110, the first controller 220, and the second controller 320.

[0074] In this implementation, the first controller 220 of the second direction control module 200 and the second controller 320 of the third direction control module 300 can be arranged along the same direction. For example, the first controller 220 and the second controller 320 can be arranged to be exposed to the second direction DR2. The first controller 220 and the second controller 320 can overlap each other in the first direction DR1 and can extend in the second direction DR2.

[0075] In one embodiment, the uneven portion 112 on the third surface of the first stage 110 may be exposed in the same direction as the first controller 220 and the second controller 320. Each of the uneven portion 112, the first controller 220, and the second controller 320 may be accessible via a cabinet CB (see reference CB). Figure 2 The opening AA (refer to) Figure 2 )Exposed to the outside.

[0076] The first housing CS1 and the second housing CS2 can be connected to each other to surround the second direction control module 200, and the second housing CS2 and the third housing CS3 can be connected to each other to surround the third direction control module 300.

[0093] Figure 9 is a cross-sectional view showing a display module position adjustment device according to an embodiment of the present disclosure. In Figure 9 , the first thread crest 10 of the first direction control module 100 (refer to Figure 4B ) may be coupled to the first thread root 20 of the second stage 210. The second thread crest 30 of the first controller 220 (refer to Figure 4B ) may be coupled to the second thread root 40 of the second stage 210. Refer to Figure 9 , and repeated descriptions of the same components will be omitted.

[0094] Figure 10B and Figure 10C are views showing the first controller 220 according to an embodiment of the present disclosure.

[0095] Refer Figure 10B and Figure 10C , in an embodiment, the first controller 220 may include a first portion 221 having a spherical shape, a second portion 222 including the second thread crest 30, and a third portion 223 in which an adjustment slot 50 is defined.

[0096] In an implementation, the travel distance LT of the first controller 220 can be determined based on the interval PI between adjacent second thread crests 30 and the rotation angle AG of the third portion 223. In an implementation, the travel distance LT can be obtained using the equation LT = (AG / 2π) × PI. For example, when the interval PI between the thread crests is “p” and the rotation angle of the third portion 223 is “a”, the first controller 220 can move “b” in the second direction DR2 (i.e., b = (a / 2π) × p). Therefore, the second stage 210 connected to the first portion 221 (see reference) Figure 4B The position of the display module can be adjusted by moving a distance "b" in the second direction DR2.
