Display Appratus {Display Appratus}

The present invention relates to a display device, and more specifically, to a display device having a circuit connection structure capable of finely controlling the arrangement between a plurality of panel modules constituting a display panel.

There are various types of display panels that implement images. For example, various display panels such as liquid crystal display panel, LED display panel, plasma display panel, and organic light emitting diode display panel. There is.

In the prior art, a plurality of panel modules are fixedly arranged to form one display panel, and there is a display module that outputs images through the one display panel. In addition, there is a prior art in which a plurality of display panels are connected to output an image larger than the image output by the single display module.

In this case, the spacing between the plurality of panel modules must be set accurately so that the plurality of panel modules can accurately output one image together. Additionally, the interval between the plurality of display panels must be accurately set so that the plurality of display panels can accurately output the entire image together.

The display panel of the prior art may have a portion (non-image portion) at the edge where no image is output, but a display panel such as the LED display panel may not have the non-image portion. Additionally, the panel module may be an LED display panel with a smaller front area than the display panel, and the panel module may not have the non-image portion.

In the case of a display panel without the non-image portion, fine adjustment of the spacing between a plurality of display modules is more important. Additionally, in the case of a panel module without the non-image portion, fine adjustment of the spacing between a plurality of panel modules is more important. For example, depending on the spacing between a plurality of LED display modules and/or the spacing between a plurality of panel modules, when the spacing between adjacent LEDs is relatively distant, a line with low luminance is visually visible, and the spacing between adjacent LEDs When this is relatively close, a line with high luminance is visually visible.

In the prior art, a control unit for controlling image output is provided in a panel module, and a plurality of panel modules forming one display panel are each connected to the control unit through an electrical circuit. In order to adjust the spacing between the plurality of panel modules when assembling a plurality of panel modules to produce one display module, there is a technology that electrically connects the control unit and the plurality of panel modules with a flexible cable.

The second task of the present invention is to provide a structure that connects a panel module to the control unit, connects the panel module and the control unit with a circuit, and allows fine spacing between a plurality of panel modules to be adjusted.

In conventional technology (for example, technology using flexible cables), in order to arrange multiple panel modules at regular intervals, everything from overall arrangement to fine spacing adjustment must be done at once, which reduces the accuracy of the spacing between multiple panel modules and makes assembly inconvenient. There is a problem with termination. The third task is to solve this problem and provide a structure that allows easy and fine spacing adjustment while setting the overall position of the plurality of panel modules.

In order to solve the above problems, a display device according to the present invention includes a display panel that outputs an image forward and includes a first panel module and a second panel module arranged on a vertical plane, and is disposed at the rear of the display panel. a control unit that controls image output of the display panel, a first recessed part fixed to one of the control unit and the first panel module, and a first recessed part fixed to the other one of the control unit and the first panel module.

The connecting portion 130 includes a locking portion 150 that allows the connecting portion 130 to be fixed to a specific position.

The second fixing part 200 of the module 1 includes a receiving part 210 that accommodates the protruding end of the connecting part 130 of the adjacent module 1. The receiving portion 210 of the module 1 forms a receiving hole 210a into which the connecting portion 130 of the adjacent module 1 is inserted. The second fixing part 200 of the module 1 includes an adjusting part 240 that moves along the third direction while in contact with the connecting part 130 of the adjacent module 1. The adjusting unit 240 allows the connecting unit 130 to move along the first direction while being coupled to the receiving unit 210. While the connecting portion 130 of the adjacent module 1 moves in either the first direction or the second direction by the adjusting portion 240 of the module 1, there is a connection between the module 1 and the adjacent module 1. The spacing can be finely adjusted.

Since the connection portion 130 of the module 1 is disposed at the side end in the first direction and the receiving hole 210a of the module 1 is disposed at the side end in the second direction, the connection portion of the module 1 ( 130) cannot be inserted into the receiving hole 210a of the module 1. However, in order to explain the configuration of the first fixing part 100 and the second fixing part 200 of the module 1, the connection part 130 of the module 1 is connected to the receiving hole of the module 1 ( It can be assumed that it is inserted in 210a). The operational relationship between the first fixing part 100 and the second fixing part 200 on this assumption is that the connecting part 130 of the adjacent module 1 is inserted into the receiving hole 210a of the module 1. The operational relationship between the first fixing part 100 of the adjacent module 1 and the second fixing part 200 of the module 1 is the same. The reason why this assumption is necessary is because the present invention can be implemented as a single display module 1, but is manufactured taking into account a situation in which a plurality of display modules 1 of the same shape are arranged and connected to each other. Hereinafter, the description will be made assuming that the connection portion 130 is inserted into the receiving hole 210a.

The insertion end portion 131 is the part that is first inserted into the receiving hole 210a. The insertion distal portion 131 includes a portion that becomes thinner along the first direction. The insertion distal end 131 has a tapered shape.

The connection portion 130 includes a head portion 135 forming an end opposite to the direction in which the connection portion 130 is inserted. The head portion 135 forms the end of the connection portion 130 in the second direction. The head portion 135 may serve to prevent the connection portion 130 from deviating from the guide portion 110 in the first direction. The head portion 135 has a thicker cross section than the connection body 133. The head portion 135 forms a stepped portion in a direction away from the central axis of the connection body 133. The head portion 135 may be caught on the guide portion 110 without being inserted into the guide hole 110a.

The connection portion 130 includes an adjustment response portion 137 that contacts the adjustment portion 240 . The adjustment response portion 137 may be formed on the connection body 133. The adjustment response portion 137 may be formed by recessing the surface of the connection body 133 in a direction perpendicular to the first and second directions. The adjustment response portion 137 may be formed by recessing the surface of the connection body 133 along the third direction. The adjustment counterpart 137 may include an inclined surface. The adjustment response portion 137 slides with the contact portion 241 of the adjustment portion 240 as the adjustment portion 240 moves, and the connection portion 130 moves accordingly. Details about this will be described later.

The connection portion 130 forms a main groove 130a extending in the first and second directions. The main groove 130a may be formed by a depression in the surface of the connection body 133. The main groove 130a may be formed by recessing the surface of the connection body 133 in a direction perpendicular to the first and second directions. The main groove 130a may be formed by recessing the surface of the connection body 133 along the fourth direction. The main groove 130a guides the relative movement of the engaging portion 150 with respect to the connecting portion 130. The locking end portion 151 is inserted into the main groove 130a and can move relative to the extension direction of the main groove 130a.
