Description

The present invention relates to a flexible sheet display that is flexible and can be easily transported and temporarily installed.
More specifically, the present invention relates to a flexible sheet display that is used by temporarily covering a side wall of a building or the like for an outdoor event, or affixing to a pillar or wall in a building for an advertisement.

Conventionally, a large screen-like lighting device using LEDs has been developed.
For example, although an illumination device (see Patent Document 1) has been developed as an outdoor lighting device, there is a limit in scale.
Therefore, a large-scale video spectral rendering device that can be distant in the field has been provided (see Patent Document 2).

This is to form a panoramic screen by unitizing LEDs and attaching them to a support that is made up of a large number of forests on a basic board.
However, since the foundation work is required, the occupied area becomes very large, which increases the cost.
In addition, the panoramic screen is set in a very wide range and has the advantage of being able to be distant. On the other hand, it is fixed and cannot be folded.
Moreover, since it is permanently installed on the foundation board, its movement is naturally impossible.

The best mode for carrying out the present invention will be described below with reference to the drawings.
[First embodiment]
FIG. 1 shows a first embodiment of the flexible sheet display of the present invention.
The flexible sheet display 1 according to the first embodiment is used for an outdoor event, for example, and is provided so as to cover a side wall of a building as shown in FIG.
The flexible sheet display 1 includes a light emitting means 2 and a flexible lattice-shaped holding sheet 3 for attaching the light emitting means 2.
The light-emitting means 2 are arranged in a matrix at the grid point positions of the grid-like holding sheet 3, and the individual light-emitting means 2 produce a colored light image as a whole under wiring control.

As the lattice-shaped holding sheet 3, a net that is rounded or folded in either the vertical or horizontal direction, in the present embodiment, is formed from a synthetic resin or synthetic fiber.
In this case, the lines constituting the net may be a bundle of a plurality of lines, or may be a monofilament.
If the net is made of synthetic resin or synthetic fiber, the flexible sheet display 1 itself is light and can be easily transported even if the display area is increased.

In addition, it can be bent in any direction, and can be folded down by winding or the like, so that it can be easily transported.
Moreover, even if it hangs down on the outer wall of the building by enlarging the eyes of the net, natural light enters through the eyes of the net from the window, so it is possible to see the outside from the inside.
In addition to being able to see the colored light image displayed on the flexible sheet display 1 from the outside, it is also possible to see the outdoors from inside.

Each light emitting means 2 includes, for example, three primary colors of light, for example, a red light emitting diode, a green light emitting diode, and a blue light emitting diode.
Since these light emitting diodes emit only light of a specific wavelength, power consumption is much smaller than incandescent lamps, and there is an advantage that a bright and clear colored light image can be displayed.
Further, the sheet edge 1a of the flexible sheet display 1 is provided with a horizontal driver and a vertical driver having wiring, and each light emitting means 2 can be arbitrarily driven to display a colored light image (FIG. 4). reference).
The functions of the horizontal driver and the vertical driver will be described later, but they have flexibility.

FIG. 2 is an enlarged schematic view showing the flexible sheet display 1 of FIG.
FIG. 3 shows a cross section taken along line III-III in FIG.
The light emitting means 2, the red light emitting diode R, the green light emitting diode G, and the blue light emitting diode B are preferably covered with a transparent resin case as shown in the drawing.
The transparent resin case provided with these light emitting diodes R, G, B is mounted (mounted) on an independent small piece-like printed circuit board 5.
Therefore, the printed circuit board 5 incorporating the wiring is in a protected state without being exposed to the outside.
Here, the resin case or the printed circuit board 5 may have a triangular shape, a circular shape, or the like as long as each diode is disposed.

The small printed circuit board 5 has a size that does not interfere with the adjacent printed circuit board 5 when viewed in plan.
The printed circuit board 5 having wiring therein is connected to the horizontal direction and the vertical direction by the wiring 4 respectively, and the red light emitting diode R, the green light emitting diode G, and the like are connected by a lighting control device (not shown) via a horizontal or vertical driver. Blue light emitting diode B is lit.
In order to attach the light emitting means 2 to the grid-like holding sheet 3, the printed circuit board 5 equipped with the light emitting means 2 is directly fixed to the holding sheet 3.

For example, the terminals 51 which are mounting means provided on the printed circuit board 5 are attached to the lattice points of the lattice-shaped substrate holding sheet 3 by one touch.
A large number of light emitting means 2 are thus easily arranged in a matrix on the grid-like holding sheet 3.
If the light emitting means 2 breaks down or reaches the end of its life after use, the light emitting means 2 may be removed from the holding sheet 3 together.

FIG. 4 shows a control structure example of the flexible sheet display 1.
As shown in the figure, the flexible sheet display 1 performs lighting control of the light emitting means 2 independently by a horizontal driver H and a vertical driver V.
This control is performed using the lighting control device 6.
Video information is input to the lighting control device 6 from a video source 7 such as a DVD disk.
The video information is analyzed by the lighting control device 6 and then displayed on the flexible sheet display 1 by using the horizontal driver H and the vertical driver V.

FIG. 5 shows a lighting drive circuit of the light emitting means 2.
For the sake of convenience, a lighting drive circuit for one light-emitting diode R out of the three light-emitting diodes is shown.
One light emitting means 2 is configured including the light emitting diodes R, G, B, and this light emitting means 2 forms one pixel.

In the lighting drive circuit (arranged on the printed circuit board 5) shown in the figure, four transistors 8a to 8d are provided.

The gate voltage of the transistor 8a is stored in the capacitor 10 connected between (s) (see FIG. 6A).
In the figure, Vdd is a power supply voltage.

  Next, when the gate signal line 9a is deactivated (OFF voltage is applied) and the gate signal line 9b (included in the wiring 4 in FIG. 2) is activated, the current flow path is connected to the transistor 8a and the light emitting diode R. The path is switched to a path including the transistor 8d and the light emitting diode R, and a current is supplied from the capacitor 10 to the light emitting diode R (see FIG. 6B).

The lighting drive circuit has four transistors 8a to 8d per light emitting diode.
The gate of the transistor 8a is connected to the source of the transistor 8b.
