Hereinafter, an LED display device of the present invention will be described in detail with reference to the drawings.
In the description, the image display side (LED bar side viewed from the screen) of the LED display device is defined as the front, and the opposite side (screen side viewed from the LED bar) is defined as the rear.

<1> Overall configuration (FIG. 1).
The LED display device 1 of the present invention includes at least an LED bar 10, a screen 20, a holder clip 30, and a control device 40 (not shown).
The LED bar 10 is connected to the screen 20 via a holder clip 30. The LED bar 10 is electrically connected to the control device 40.

<2> LED bar (FIG. 2).
The LED bar 10 is a rod-like light emitting member.
The LED bar 10 includes at least an LED substrate 11 and a cylindrical holder 12, and the LED substrate 11 is inserted into the holder 12 along the axial direction.

<2.1> LED substrate.
The LED substrate 11 is a long substrate that causes the LED element 11 a to emit light in accordance with an image signal from the control device 40.
A plurality of LED elements 11 a are arranged on the surface of the LED substrate 11 with a predetermined interval in the longitudinal direction.
A connection line is connected to the back surface or the end of the LED substrate 11 (not shown). The connection line extends through the screen 20 to the control device 40 and electrically connects the LED substrate 11 and the control device 40.

<2.2> Holder.
The holder 12 is a cylindrical member that covers the LED substrate 11. The material of the holder 12 is preferably a lightweight and high strength material such as aluminum.
The holder 12 has at least an internal space 12 a, an open window 12 b, and a coupling groove 12 c that pass through both ends of the holder 12.

<2.2.1> Internal space.
The internal space 12a is a space that accommodates the LED substrate 11.
The long LED substrate 11 is inserted from the end of the holder 12 into the internal space 12a and accommodated.
Similarly, the LED substrate 11 can be removed by pulling it out from the end of the holder 12. Therefore, maintenance of the LED substrate 11 is easy.

<2.2.2> Open window.
The open window 12b is a window for communicating the internal space 12a and the outside of the holder 12 to emit light emitted from the LED element 11a to the outside.
The open window 12 b is provided on the front surface of the holder 12 along the longitudinal direction of the holder 12. The open window 12b may be covered with a transparent member.

<2.2.3> Bonding groove.
The coupling groove 12 c is a groove for engaging with a coupling convex portion 31 (described later) of the holder clip 30.
The coupling groove 12 c is provided in the rear part of the holder 12 along the longitudinal direction of the holder 12.
The coupling groove 12c has an inverted T-shaped cross section with respect to the longitudinal direction of the holder 12, and the lower end of the T-shape communicates with the outside.

<3> Screen.
The screen 20 is a lattice-like member formed by connecting a plurality of wires 21 extending in the horizontal direction vertically with a plurality of wires 22. It is desirable that the plurality of wires 21 be separated by a certain distance.
In this example, a decorative wire mesh is used in which a plurality of stainless steel wire rods 21 are alternately knitted with four wires 22 (FIG. 1). However, the present invention is not limited to this, and any lattice-like structure including a horizontal wire may be used.

<4> Holder clip (FIG. 3).
The holder clip 30 is a jig for connecting the LED bar 10 to the screen 20.
In this example, the holder clip 30 has a divided structure, and two divided bodies 30a, 30a having a shape of an Arabic numeral “5” in a side view are combined left-right symmetrically.
Each divided body 30a includes a coupling protrusion 31 for engaging with the coupling groove 12c of the LED bar 10, and a clamping groove 32 for sandwiching and fixing the wire 21 of the screen 20.
Each connecting convex portion 31 corresponds to a horizontal bar at the top of the Arabic numeral “5”. By combining the two divided bodies 30a and 30a, a T-shape corresponding to the shape of the coupling groove 12c is obtained.
Each clamping groove 32 corresponds to a curved portion of “5”. By combining the two divided bodies 30a and 30a, a ring shape that sandwiches the wire 21 of the screen 20 is obtained.
The holder clip 30 is not limited to a two-part structure, and may be a structure such as a laundry scissor whose open end is closed by a spring.

<5> Image display function.
The LED display device 1 of the present invention uses a plurality of LED elements 11a arranged in a matrix on the front surface of the LED bar 10 as pixels, and controls the light emission by the control device 40, whereby various kinds of moving images including a moving image are displayed on the front surface of the screen 20. Images can be displayed. Since the display image control technique by the control device 40 is well known, it will not be described in detail here.
Since each LED element 11a is fixed in the LED bar 10 and the LED bar 10 is fixed to the front surface of the screen 20 via the holder clip 30, unlike the prior art, the relative position between the LED elements 11a is difficult to move. . Therefore, a finer image can be clearly displayed.

[Assembly method of LED display device]
Next, a method for assembling the LED display device will be described in detail with reference to the drawings.

<1> Installation of a screen.
The screen 20 is suspended at the place where the LED display device 1 is installed.
Since there is a gap between the upper and lower wires 21 in the screen 20, it can be used as a window blind. This makes it possible to display a desired image at the same time while taking in the daylight and wind from the outside into the room.
Moreover, it can also be hung on a wall surface instead of a window.

<2> Attaching the holder clip.
A holder clip 30 is attached to the wire rod 21 of the screen 20.
The holder clip 30 is attached to an arbitrary location on the screen 20 in correspondence with the installation location of the LED bar 10.
In this example, two wire rods 21 and 21 adjacent to each other in the vertical direction are sandwiched and fixed by the sandwiching grooves 32 and 32 of the two divided bodies 30a and 30a (FIG. 4).
First, the divided body 30a is covered from above the upper wire 21 so that the holding groove 32 faces downward. Subsequently, from the lower side of the lower wire 21, the divided body 30 a is lifted with the holding groove 32 facing upward, and the two divided bodies 30 a and 30 a are combined with the two wires 21 and 21 being sandwiched.
Both divided bodies 30a and 30a are temporarily fixed by a known method such as adhesion or tape fastening.

<3> Connection of LED bars.
The LED bar 10 is connected to two holder clips 30 attached at the same height of the screen 20.
The coupling groove 12c at the end of the LED bar 10 is aligned with the side surface of the coupling convex portion 31 of the holder clip 30, and the LED bar 10 is slid in the horizontal direction to engage the coupling convex portion 31 in the coupling groove 12c (see FIG. 5).
By engaging the coupling convex portion 31 with the coupling groove 12c, the coupling convex portion 31 is limited within the coupling groove 12c, and the two divided bodies 30a and 30a are fixed to each other.
Similarly, the LED bar 10 is connected to at least two holder clips 30 each.
Finally, a connecting line extending from each LED bar 10 is connected to the control device 40.
Thus, the LED display device 1 of the present invention is very easy to assemble.
Further, the LED bar 10 can be detached from the screen 20 simply by pulling the LED bar 10 from the holder clip 30. And if the position of the holder clip 30 is changed, the installation position of the LED bar 10 can be changed easily.
Furthermore, the LED elements 11a for one row can be removed together by simply pulling out the LED substrate 11 from the holder 12 with the LED bar 10 attached to the screen 20. Therefore, inspection and replacement of parts are easy.

<4> When diverting an existing screen.
As described above, the case where the LED display device 1 is newly installed has been described. However, the LED display device 1 of the present invention is a simple operation of holding the wire rod 21 of the existing screen 20 with the holder clip 30 and attaching the LED bar 10. The existing screen 20 can be diverted to a display device.
