FIG. 1 shows the configuration of a light emitting circuit block according to the present invention, which includes a sensor 1 and a light emitting element 2.
One light emitting circuit block 4 is constituted by the signal processing circuit 3 which causes the light emitting element 2 to emit light in response to the output signal of the sensor 1.

The sensor 1 detects a physical quantity or a chemical quantity,
Various things having a function of converting into an electric signal can be used according to the usage mode, for example, light quantity, light rays, temperature,
Humidity, position, distance, speed, acceleration, angle, rotation speed, force,
A detector for electric power, current, gas concentration, etc. can be used alone or in combination with other members such as a projector such as a limit switch.

Further, the sensitivity of the sensor 1 can be selected appropriately,
The sensitivity adjustment of the sensors may be performed collectively for all the sensors on the panel, but it is more preferable to provide an external adjustment function for each sensor in consideration of maintainability. In addition, it is preferable to use a small sensor 1 having a small installation area because the sensor 1 needs to be installed together with the light emitting element 2 in a limited space.

As the light emitting element 2, various ones such as LEDs, electric bulbs, fluorescent lamps, neon tubes, etc. can be used, but the color and brightness according to the mode of use as a display panel, the color and brightness of the entire display surface. Considering the balance of the combination, the size of the display space, the limitation on the space, and the like, it is preferable to use an appropriate one that makes the display easy to see as the entire panel.

The signal processing circuit 3 receives the output signal of the sensor 1 and outputs a control signal to the light emitting element 2 to cause it to emit light.
The light emitting state of the light emitting element 2 is controlled in brightness, light emitting time and the like by the control signal, and the control signal is arbitrarily set by the internal circuit of the signal processing circuit 3. It is more preferable that the various conditions of the control signal can be adjusted from the outside in consideration of maintainability and the like.

As shown in FIG. 2, these parts are housed in a box-shaped casing 4c having housings 4a and 4b for the sensor 1 and the light emitting element 2 on the upper surface, and one light emitting circuit block 4 is provided.
Are configured.

A signal processing circuit 3 is housed inside the light emitting circuit block 4, and the signal processing circuit 3 has an electrode connector 4.
The sensor 1 and the light emitting element 2 are operated by receiving the electric supply from d, and the sensor 1 is operated by the adjusting trimmer 4e provided on the side.
And the control signal supplied to the light emitting element 2, such as the light emission start time, the light emission duration time, and the brightness of the light emitting element 2, can be adjusted.

In addition to the box shape, the housing 4c may have an arbitrary shape such as a circular shape or a polygonal cylindrical shape in a plan view, and one light emitting circuit block 4 may have a sensor 1 or a light emitting element. It is optional to configure the element 2 so as to accommodate a plurality of elements.

FIG. 3 shows a basic structure of a display panel of the present invention, in which a large number of light emitting circuit blocks 4 having the above structure are arranged in a grid pattern in the same plane.
Here, "lattice-like" means a state in which the cells are regularly arranged in the vertical and horizontal directions with a constant interval in the vertical and horizontal directions. The overall size and shape of the panel 5 is appropriately selected according to the usage mode and installation area of the panel, and it is also possible to form the same curved surface depending on the usage mode and the type of sensor.

In this case, in the panel 5, the receptacles into which the electrode connectors 4e of the light emitting circuit block 4 are fitted are arranged on the substrate, and current is supplied to the respective light emitting circuit blocks 4 through the receptacles to connect the respective light emitting elements 2 to each other. The processing circuit and wiring for making it emit light are unnecessary. Of course, a processing circuit may be provided.

Further, by arranging the light emitting circuit blocks 4 in a grid pattern, it is possible to easily visually recognize a continuous change in a physical quantity or the like in the same plane, but the invention is not limited to this. A configuration in which they are discretely arranged in the same plane may be used.

FIG. 4 and FIG. 5 show a first embodiment of the display panel of the present invention having the above-mentioned structure, in which an infrared projector 6 is installed on the ceiling and an infrared detector is used as the sensor 1. A small light bulb is used as the light emitting element 2, and the light emitting circuit block 4 is configured by accommodating them in the housing 4c whose upper surface is formed in a square shape of about 2.5 cm, and the light emitting circuit block 4 is placed on the indoor floor surface. The display panel 5 is configured by arranging a large number in a grid pattern. The light emitting circuit block 4 turns off the light emitting element 2 while the infrared light of the infrared light projector 6 is being projected onto the sensor 1, and when the infrared light is no longer input to the sensor 1, it has a predetermined delay time and is constant. The light emitting element 2 is made to emit light while changing the brightness within the time.

According to the structure of this embodiment, when a person walks on the display panel 5, the infrared light entering the sensor 1 is temporarily blocked, so that the light emitting element 2 in the light emitting circuit block 4 at that position is blocked. Only the light is emitted, and as shown in FIG. 5, the panel surface can be made to shine by edging a human footprint. In addition, since it is bright immediately after the start of light emission and then gradually darkens,
You can visually check and enjoy the shape and change of light, and enhance the visual effect. In this embodiment, the display color of the light emitting element 2 is arbitrary.

Further, since the signal processing circuit 3 is built in each of the light emitting circuit blocks 4, the structure and wiring of the display panel 5 are simplified, and maintenance can be performed by exchanging one light emitting circuit block 4 as a unit. Therefore, there is an advantage that the workability is excellent.

FIG. 6 shows a second embodiment of the display panel of the present invention, in which the light emitting circuit block 14 is connected to the sensor 1.
And a plurality of light emitting elements 2 are arranged in a grid on the same plane to form a panel 5, and the plurality of light emitting circuit blocks 14 and the signal source 7 sensed by the sensor 1 are collectively controlled. The signal processing device 13 is separately provided.

According to the configuration of this embodiment, the signal emitted from the signal source 7 and reflected by the object 8 is detected by the sensor 1,
In response to this, the signal processing device 13 outputs a control signal to the light emitting element 2 corresponding to the sensor 1 to cause the light emitting element 2 to emit light appropriately.

As described above, if a plurality of light emitting circuit blocks 14 are arranged on the same surface, the change in the physical quantity detected on the same surface can be displayed, and in the signal processing device 13, such light emitting circuit blocks can be displayed. The block 14 and the signal source 7 may be configured to be collectively controlled. When the signal source 7 is a physical quantity of the surrounding environment such as temperature and illuminance, it is not necessary to provide the signal source 7 in particular.

FIG. 7 shows a third embodiment of the display panel according to the present invention. This is a display panel 5 constructed by arranging the light emitting circuit blocks 4 in a lattice pattern on the wall surfaces inside and outside the room. The sensor 1 is placed at a position slightly away from the display panel 5.
A signal source 7 that outputs a signal that can be sensed by is installed, and the signal is radiated radially to the panel surface.

According to the configuration of this embodiment, changes in the shape, displacement state and other physical quantities of the object 8 between the display panel 5 and the signal source 7 are enlarged and displayed on the display panel 5, which is easy to see. Can also be displayed with a high visual effect. The display panel 5 can be installed in an indoor space such as a floor or a ceiling, or other outdoor space.

FIG. 8 shows a fourth embodiment of the display panel of the present invention, in which the light emitting circuit block 24 is configured to be capable of transmitting a predetermined signal between the adjacent light emitting circuit blocks 24 and has the same surface. A display panel is formed by arranging the display panel in a grid pattern on the top. The signals to be transmitted include a detection signal of the sensor 1 and a light emission signal of the light emitting element 2. In this way, by transmitting and receiving a signal between the adjacent light emitting circuit blocks 24 and controlling the light emitting state of the light emitting element 2 in accordance with the signal, for example, as shown in FIG. 9, the light emitting circuit block 24a at the central position in the figure is shown.
When the sensor 1 detects the signal, the information can be uniformly transmitted on the plane like the spread of the ripples A, B, and C, and the state can be displayed.

Of the constituent parts of the display panel 5,
By configuring the detection actuating device by using an arbitrary actuator instead of the light emitting element 2, various information can be transmitted or the device can be actuated according to changes in the physical quantity on the same plane. That is, the sensor and the actuator are adjacently formed integrally with each other, and a plurality of the sensors and the actuator are arranged on the same surface, more preferably in a grid pattern, and the actuator is operated according to the detection signal of the sensor. As an embodiment, for example, a fan is installed adjacent to the sensor, a windmill is arranged in front of the fan, and the fan is operated according to a detection signal of the sensor to turn the windmill.
