A step is formed in the vertical direction on the rear side of the T-shaped column 13, and one side of the T-shaped column 13 comes into contact with this step. Furthermore, a plurality of stepped pins 21' are attached to the upper surface part 20 of the housing 12 (note that the lower surface part may be used, but for convenience, it is assumed to be the upper surface part), while the lower surface part 22 is provided with a plurality of stepped pins 21 as shown in FIG. As shown in FIG. 2, an elongated hole 23 extending in the left-right direction is formed at a position vertically aligned with the stepped pin 21. In addition,
The casing 12 is symmetrical in a vertically and horizontally inverted state except for one stepped pin on the side surface 18 on the center side.

A plurality of display elements 11 (26 in total in 2 rows and 13 columns in this embodiment) are arranged on the front surface of the casing 12 with predetermined clearances and flatness to prevent distortion due to thermal expansion. A controller section connected to the display element 11, a part of the driver, and electric circuits such as a power supply are built into the enclosure 12, and these enclosures 12, 26 display elements 11 and their electrical circuits are built in. The circuit forms one display block 24.

A plurality of positioning holes 26 into which stepped pins 19 are inserted are formed in the center plate 25 of the T-shape 13.

In this embodiment, four positioning holes 26 arranged to form a quadrilateral correspond to a pair of display blocks 24 arranged facing each other on the left and right sides. A plurality of sets are formed in the vertical direction of the center plate 25.

That is, as shown in FIG. 3, the stepped pins 19 of the pair of display blocks 24, which are disposed facing left and right with respect to the T-shape 13, are inserted into two positioning holes 26 that are arranged diagonally to each other. inserted.

In the large-sized display device configured as described above, the left column 14, the T-shaped column 13, and the right column 15 are held at predetermined intervals on a fixed object such as a caulking wall, and the casing 12 is held at a predetermined interval. A display element 11 is disposed in front of the display block 24 to form a display block 24.

Then, the stepped pin 19 of the display block 24 is positioned by sliding it to the right (in the left and right direction of the arrow) towards the positioning hole 26 of the center plate 25 of the T-shape 13, and then the column mounting plate 17 is attached to the column 14 on the left side. and secure it with screws, etc. Next, move the other display blocks 24 in the same direction as the previously fixed display block 24, up, down, left and right,

The flatness of the gap is kept constant.

In addition, since the display blocks 24 are assembled while sliding each display block 24 toward the center (T-shape 13), even though the display is large, the display blocks are all placed in the front without the need for people to go behind the pillars. Since it can be assembled from the ground up, there is no need to prepare a space for assembly behind the pillar, and since the display block has a symmetrical shape that is flipped vertically and horizontally, one type of display block can be assembled for both the left and right sides.
Excellent expandability. Furthermore, since the T-shaped pillar and the housing support pillars at both left and right ends are located within the depth range of the display block, the housing support pillars do not protrude from the display block 24, making it possible to construct a thin display device. .

As explained in detail about the invention, by dividing the display blocks into appropriately sized display blocks, they can be easily transported and assembled without the use of mechanical power such as a crane. It is equipped with a stepped pin and an elongated pin, and a stepped pin is provided on the side of the display block, and a hole is formed in the T-shaped column to insert the stepped pin, so a certain clearance and flatness can be ensured. As it can be assembled from the front, the pillar can be attached to a fixed object such as a wall for better stability.It also saves space, and the display block can be flipped vertically and horizontally to create a symmetrical shape. It is highly expandable because the blocks can be assembled in common on both the left and right sides.
