Next, look at the operation of the left and right connecting member 180, as shown in Figure 8 by aligning the outer frame 110 and another outer frame 110 'laterally to match the fastening holes 182 It is coupled to the fastening member 184 through the fastening hole 182.

The fastening member 184 is bolted to form a handle 186 at one end to facilitate the user's tightening operation, the tightening direction of the fastening member 184 of the fastening hole 182 so that a separate nut is not required The thread is formed in the outer fastening hole 182 with respect to.

At this time, the side reinforcing piece 185 is formed on the inner side fastening hole 182 of the outer frame 110 to deepen the depth of the fastening hole 182, thereby improving the supporting force.

The inside of the handle 186 is provided with a magnet can be attached to the inside of the outer frame 110 made of steel has the advantage of easy storage.

Then, a buffer pad 220 is attached to the side of the outer frame 110 to mitigate the impact when the side of the outer frame 110 'is coupled, thereby increasing the support strength by the frictional force.

In this way, by combining the electronic display panel 100 vertically, left and right, it is easy to install and dismantle in forming the large electronic display panel 100, there is an advantage that can maximize the advertising effect by the large electronic display board.

In the case of a large display board, a plurality of display boards are provided and set by a position control button formed on a lower surface of the center frame to display information for each location.

An opening hole 142 is formed at the center of the cover 140 when the position is set by the position control button, and is displayed on the display unit 212 through the opening hole 142, thereby simplifying operation.

As described above, according to the LED display board according to the present invention is composed of the outer frame and the center frame, combined with the bar-shaped LED board to maintain a constant interval, and is not affected by strong wind by the permeability, separate the LED board case To be accommodated in the protected and waterproof, and by the sealing member and the cover on the central frame provided with the control, there is an advantage that can be used without limitation in weather conditions.

In addition, the upper and lower, left and right connection member is provided to increase the size of the LED display board to maximize the advertising effect, there is an advantage that easy installation and disassembly, easy to move.

In addition, by solving the structural problem that the front of the signboard is completely blocked, when you want to create a unique and distinctive atmosphere by using the ambient light on the back of the signboard at various event events such as broadcasting stations, there is an advantage to create the atmosphere as the director intended. .

In addition, when the large display board is configured by the connecting member, the display unit may be set while checking the display unit at the rear of the display board, thereby providing convenience of operation.
