[0002]

2. Description of the Related Art As one of display devices used in a traffic monitoring system, a water treatment monitoring system, a power monitoring system and the like, there is a block fitting type display device. This display device
As shown in FIG. 4, a large display panel configured by selectively fitting an LED type block display unit 20 to a required cell in the lattice-shaped frame 10 is provided. Block display 2
For 0, various devices such as a surface display 20a, a numeric display 20b, a character display 20c, and a level display are used according to the image configuration of the display panel. Usually, the dimensions and shape of the frame 10 also change for each display panel. A conventional block-fitting display device connects the same type of block display to a dedicated driver separately provided outside the display panel, and centrally controls each driver with a controller.

Reference numeral 11 denotes a frame-shaped outer frame to which the frame 10 fits, 12 denotes a resin-made surface mosaic block fitted from the front side to the non-light-emitting cell, and 13 denotes a filter in the light-emitting cell. It is a frame mosaic block made of resin that is fitted from the front side to the square for mounting the 14.

[0004]

In such a conventional block fitting type display device, since a large number of block display devices are connected to a driver for each type, wiring work is difficult. In order to make the wiring work more efficient, a connector relay sheet or the like is used. However, even in the case of a large display panel, the wiring work is difficult. In addition, the rear side of the display panel could not be prevented from having a complicated structure by wiring.

The present invention has been made in view of such circumstances, and a connector board is provided on the back side of a lattice-like frame, and a block display fitted to the frame is directly connected to the connector, thereby using an electric wire. An object of the present invention is to provide a block fitting type display device which has a simple structure without wiring and is easy to assemble.

[0006]

According to the present invention, there is provided a block-fit type display device, wherein a grid-like frame having a shape corresponding to a display panel is fitted to each cell of the frame according to an image configuration of the display panel. And a block display in which a connector is integrally provided on each back surface, and arranged side by side on the back side of the frame, each having an area corresponding to a predetermined number of cells of the frame, and A connector board in which a connector to be fitted with a connector of the container is provided on the surface corresponding to each cell of the frame, and a block display provided on the back side of each connector board and connected to the connector of each connector board. And a driver on which a driving circuit for driving is mounted.

Normally, various block indicators such as a surface indicator, a numeric indicator, a character indicator, and a level indicator are fitted to the frame. Therefore, it is desirable that the drive circuit mounted on the driver board is a general-purpose driver that can drive the block display regardless of the type of block display connected to the connector of the board.

The connector board is desirably a unit board having the same dimensions and shape corresponding to a predetermined number of cells of the frame. In this case, the dimensional shape of the unit substrates arranged side by side on the rear side of the frame changes only for each fixed unit, whereas the dimensional shape of the frame changes variously depending on the type of display panel required. Therefore, there is usually a portion on the back side of the frame where no connector board exists. In order to cope with this, a conventional block indicator with a line is attached to a cell where no connector board exists, and the line is connected to a surplus connector of a nearby connector board. By doing so, it is possible to construct a display panel of any size and shape despite combining unit boards of the same size.

[0009]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic front view showing an example of a block fitting type display device according to the present invention, FIG. 2 is a schematic side view, and FIG. 3 is a schematic rear view.

The present display device has a lattice-like frame 10 forming a skeleton of a display panel, and a large number of block display devices 20 (20a, 20b,
20c), a plurality of connector boards 30 arranged side by side on the back side of the frame 10, and a plurality of driver boards 40 respectively attached to the back face of each connector board 30.

The frame 10 is basically the same as that used in the conventional display device shown in FIG.
It is configured using a 5 mm square grid as a basic unit. As shown in FIG. 4, the frame 10 is fitted into the frame-shaped outer frame 11, and the surface mosaic block 12 made of resin is fitted from the front side into the cell of the non-light-emitting portion. This is the same as the conventional display device in that the claw-type frame type mosaic block 13 is fitted to the light emitting portion from the front side, and the filter 14 is attached to the square of the portion. The dimensions and shape of the frame 10 are appropriately changed depending on the display panel to be manufactured.

The block display 20 is an LED display, and a surface display 20a, a numerical display 20b, a character display 20c, and the like are used depending on a configuration image of the display panel. The surface indicator 20a is fitted into the mesh of the frame 10 from the front side, and a pin type connector 21 is attached to the tip of a leg 22 extending to the back side.
It has a structure with attached. Number display 20b is 7
This is called a segment numeric display, and is fitted and held on the frame 10 from the front side over a plurality of cells. The character display 20c is also fitted and held on the frame 10 from the front side over a plurality of cells. Numeric display 2
Each of Ob and the character display 20c has a leg 22 extending to the back side, and has a structure in which a pin type connector 21 is attached to the tip.

Each of the connector boards 30 is a unit board having the same dimensions and shape corresponding to a predetermined number of meshes. Here, the 8 × 8 mesh is a predetermined number of meshes, and if the size of one square is 15 mm square, all the connector boards 3
The size of 0 is about 120 × 10 mm. The surface of each connector board 30 corresponds to each cell. A socket type connector 31 is attached. If the connector board 30 corresponds to an 8 × 8 grid, 8 × 8 connectors 3 are mounted on the surface of the connector board 30 at a constant pitch. Then, the connector 21 of the block display 20 fitted and mounted on the frame 10 is connected to the corresponding connector 31 on the back side.

As for the assembly of the block display 20 and the connector board 30, after the connector 21 of the display 20 is connected to the connector 31 of the connector board 30, the connector board 30 is attached to the frame 10 to mount the display 20. The procedure may be a procedure of mounting the connector board 30 on the frame 10 or a procedure of mounting the display 20 on the frame 10 and connecting the connector 21 to the connector 31 of the connector board 30 after the connector board 30 is mounted on the frame 10.

Now, the size of the connector board 30 is about 120
× 120 mm, and the size of the frame 10 is 1.2 ×
If it is 1.2 m, 10 × 10 substrates 30 are used. In this case, all the meshes correspond to the connectors 31 of the connector board 30. That is, the shortage of the connector 31 does not occur. However, normally, the size of the frame 10 does not become an integral multiple of the size of the connector board 30, and as a result, as shown in the illustrated example, the connector board 30
Occurs in the periphery of the frame 10 and the like,
In this part, the connector 31 is insufficient. For this reason, in a portion where the connector 31 is insufficient, a conventional line display shown in FIG. 4 is used as the block display 20. Then, the connector 23 attached to the end of the line is connected to the surplus connector 31 of the nearby connector board 30. The indicator with a line is fixed in the mesh by snap-fitting.

A driver board 40 mounted on the back of each board 30 has a drive circuit 41 mounted on the back.
The drive circuit 41 is connected to all the connectors 31 mounted on the surface of the connector board 30, and the connectors 31
Is a general-purpose type that can drive the display 20 regardless of what type of block display 20 is connected to it.
Central control is performed by a controller (not shown). Note that 42
Reference numeral denotes an input / output connector mounted on the driver board 40.

In this display device, the block display 20 fitted and held in each cell of the frame 10 has an integrated connector 21 on the back side, and the connector 21 is connected to the connector 31 of the connector board 30 on the back side. Since the connection is made, wiring work with electric wires becomes unnecessary.

Since the connector board 30 is a unit board having the same dimensions, any size and shape of display boards can be easily handled by changing the number of display boards. Further, since the driver board 40 on which the general-purpose drive circuit 41 is mounted is mounted on the back surface of the connector board 30, the type of the block display 20 to be used is not limited. In other words, in the case of a display panel of any size and shape, the frame 1
The display panel can be constructed simply by arranging the connector boards 30 on the back side of the block 0 and mounting the block display 20 on the frame 10.

Depending on the size and shape of the display panel, the frame 1
Although a portion where the connector board 30 does not exist is formed on the back side of the edge of the connector 0, the indicator 20 with a line is used only in the portion where the connector board 30 does not exist. Since the connector 31 is used, both the number of lines and the line length are small, and a complicated wiring operation is unnecessary.

[0020]

As described above, the block fitting type display device according to the present invention has a connector board provided on the back side of a lattice-shaped frame, and a block display fitted to the frame is directly connected to the connector. As a result, wiring by electric wires is not required, and the assembling and wiring work is very easy. Further, the wiring structure on the back side of the display panel becomes very simple. Further, there is an advantage that the size of the frame can be easily changed by adjusting the number of connector boards.
