[Problem to be solved by the invention]

However, since the display device described above is configured to be visible only in the presence of sunlight, there has been a problem in that it cannot exhibit any display function at night.

The present invention has been made in view of the above-mentioned problems, and its purpose is to provide a display device that illuminates the display device from the inside at night or when the surrounding area is dark, and enables display at all times. [Means for Solving the Problems] In order to solve the above-mentioned problems, the present invention provides a casing that includes a transparent portion on the front side and an opaque fluid sealed inside.
A type of display in which a plurality of display members each having a colored part on the surface and displaceable by a magnetic drive device are provided, and the colored parts of the plurality of display members are selectively brought into contact with and separated from a transparent part to display an image. In the device, the colored portion of the display member is formed by laminating the light diffusing member and the colored film in this order, and
The present invention is characterized in that a light emitting device for illuminating the colored film in a dark state is provided on the back side of the light diffusing member and the colored film.

[Effect]

In the dark state, the colored film of the display member that is in contact with the transparent part of the casing is energized and illuminated by the light emitting device on the back side of the colored film to display a display.

C Embodiment] The details of the present invention will be explained below with reference to embodiments shown in the attached drawings.

FIG. 1(A) shows a side cross section of a main part of an embodiment of the device of the present invention, which has a back surface portion 2 that faces a transparent body 3 provided on the front side with a gap in between, and A casing 1 is formed in the portion 2, and includes a large number of recesses 5, which are formed as movement paths for the body of the display member 6, which will be described later, in the vertical direction of the drawing and from the front side to the back side of the drawing.
An opaque liquid 4 is sealed inside. and,
Each of the large number of recesses 5 provided in the back part 2 has a larger opening area than the recess 5, and a transparent body 3 of a rectangular frame 7 has a lamp 8 disposed in the internal space. A head formed by laminating and fixing a light diffusing member 10 such as frosted glass and a colored film 9 having a desired color and having light transmittance in sequence is provided on the surface facing the . On the back side of the display member 6, a display member 6 is provided with a body having a shape that can freely appear and retract into the recess 5 and a permanent magnet or a soft magnetic material 11 at one end is inserted into the recess 5. An excitation coil 12 having a voltage application terminal I4 is attached to the outer peripheral surface of the recess 5, and a voltage from a lighting power source 18 is applied to the lamp 8 via a lighting switch 19. A terminal 13 is provided.

A display device in which such display members 6 are arranged two-dimensionally is provided with a control device 15 including a microcomputer 17 equipped with a RAM and a ROM. A light sensor 16 for detecting the brightness and darkness of the display member 6 is provided on its output side with a lighting switch 19 connected to the voltage application terminal 13 of the lamp 8 provided for each display member 6. ing. Then, in the RAM, when the surroundings become dark, that is,
The light amount value at which the color of the colored film 9 can be visually recognized from the outside is stored as a reference value. In addition, the ROM contains a display control program that selects the display member 6 corresponding to the image or character to be displayed and manually applies an energizing signal to the excitation coil 12, and the output of the optical sensor 16 and the RAM. Compare it with the memorized reference value and set the optical sensor 1.
When it is detected that the output of the display member 6 has decreased below the reference value, it is constantly detected whether or not the detected output matches the selection energizing signal of the display member 6.
A control program is stored that only closes this.

The operation of the device configured in this way will be explained with reference to the flowchart shown in FIG. 2. In step Sl), when the amount of light detected by the optical sensor 16 is compared with a reference value stored in the RAM, no dark state is detected. Sometimes the display member 6 is selected according to a display control program stored in ROM.
energizes the excitation coil 12 to repel the permanent magnets 11, displaces them in the horizontal direction, eliminates the opaque liquid 4 present in the front surface, and removes the light diffusing member 10 of the display member 6.
- is brought into contact with the transparent body 3, and the colored film 9 is passed through this.
The desired display is performed by displaying the colors of the image (Step 3). When the output of the optical sensor 16 is detected and the operating state is detected, the lighting switch 19 connected to the lamp 8 of the display member 6 which has been selectively activated is activated according to the display control program, and the lighting switch 19 is activated. The voltage of the power source 18 is inputted to the lamp 8 through this switch 19, and the colored film 9 of only the display member 6 that is in contact with the transparent part 3 is illuminated from the back side, and the light diffusing member 10 is illuminated. Colored film through 9
Display is performed by uniformly diffusing the colored lights (step S2).

FIG. 1(B) shows a modification of the above-mentioned kid cell type display member, in which a light diffusing member 10 is viewed from the surface side of the frame 7.
, a colored film 9, and an electroluminescent (hereinafter referred to as EL) 20 are sequentially laminated, and a lead wire for exciting the EL 20 is taken out to the outside through the space and a permanent magnet or soft magnetic material 11.

Further, it is also possible to provide a configuration in which a light emitting device is provided in place of the EL.

〔Effect of the invention〕

As described above, according to the present invention, there is provided a display member which is formed by a casing having a transparent part on the front side and an opaque fluid sealed inside, a colored part on the surface, and formed to be movable by a magnetic drive device. In a display device in which a plurality of colored parts of a plurality of display members are provided and the colored parts of the plurality of display members are selectively brought into contact with and separated from a transparent part to perform display, the colored parts of the display members are formed by laminating a light diffusing member and a colored film in this order. In addition, since the light emitting device for illuminating the colored film in the dark state is provided on the back side of the light diffusion member and the colored film, the colored film can be illuminated from the back side even in the dark state where the display function is lost. The colored light can be uniformly diffused and displayed, making it possible to fully exhibit the display effects of advertisements and the like even in a dark state.
