FIG. 3 is a perspective view showing a state in which a pair of plates constituting the flip-dot display device are removed, and FIG. 4 is a front view showing an operation process of the flip-dot display device.

The flip-dot display includes a display element 100 and a driving element 200. The driving element 200 drives the display element 100 in a flip or rotating manner in an electromagnetic manner.

The display element 100 is composed of a polyhedron 110 having a rotation axis 120 and the driving element 200 is formed in the form of an electromagnet array as will be described later. In this case, a pair of plates 300 (310, 320) for mechanically supporting the display element 100 and physically mounting the electromagnet array as the driving element 200 are provided with the display element 100 therebetween / RTI >

As the display element 100, a surface 112 exposed between a pair of plates 300, 310 and 320 of the surface of the polyhedron 110 functions as a display surface, and the center of both sides 114 of the polyhedron 110 Both ends of the rotation shaft 120 protruding from the pair of plates 300 and 310 and 320 are pivotally supported at the center of the pair of plates 300 and 310 and 320, respectively. In an embodiment, the body of the polyhedron 110 is illustrated as being composed of a hexahedron, and the display surface 112, which is mutually independent, can be realized as four surfaces according to flip or rotation.

Accordingly, in the embodiment, when the flip or the rotation angle of the polyhedron 110 is controlled in units of 90 degrees, the number of colors that can be displayed is increased corresponding to the number of the display surfaces 112 in comparison with the conventional flip-dot display In the embodiment, a specific pattern such as a character or a graphic image can be expressed in various colors using four colors.

In this case, it is preferable that the display surface 112 is formed as a square. In other words, when the flip-display display elements 10 are arranged in an array form and are formed of the assembly module 1 of FIG. 5 to be described later, the display surface 112 is formed in a rectangular shape, By increasing the area fraction of the display surface 112 in the entire area of the display surface 1, it is possible to minimize the area of the display surface.

At least one end of the rotating shaft 120 is provided with a permanent magnet having a polarity of N and S, that is, a magnetic body 122. The magnetic body 122 interacts with pulsed electromagnetic force applied from an electromagnetic array, which will be described later, to operate the rotating shaft 122 to the polyhedron 122 in the form of flip or rotate.

As the driving element 200, the electromagnet array is provided in a form in which a plurality of magnetic dipoles 230a, 230b, 230'a, and 230'b, which are electromagnetically induced, are mutually intersected. In the embodiment, the electromagnet array in which four magnetic dipoles 230a, 230b, 230'a, and 230'b are arranged in an alternating manner is integrally formed in each of the receiving grooves 314 of the first plate 310 of the pair of plates And an end of the rotation shaft 120 is inserted into the shaft hole 312 at the center or intersection thereof.

Each of the magnetic dipoles 230a, 230b, 230'a, and 230'b may have a shape in which a coil is wound along the circumference of a circular pole, and the detailed illustration of such a magnetic dipole is omitted for convenience. Although not shown in the drawing, each magnetic dipole 230a, 230b, 230'a, and 230'b may be formed in such a manner that these circular poles are fixed in the receiving groove 314 formed as the peripheral edge of the shaft hole 312, (Not shown).

Referring to FIG. 4, an electromagnetic force is induced in each of the plurality of magnetic dipoles 230a, 230b, 230'a, and 230'b by a pulse current alternately applied along the flip or rotating direction of the polyhedron 110 . For example, when a pulse current is applied to each of the other pair of magnetic dipoles while the pulse current is turned off in any one of the magnetic dipoles 230'a and 230'b and the magnetic dipoles 230a and 230b, And the specific display surface 112 of the polyhedron 110 is opposed in the display direction by being flipped or rotated by the N, S electromagnetic force of the magnetic dipole pair applied with the pulse current. In this case, the signal data relating to the pulse current applied from the outside is based on the signal data relating to a specific pattern such as a character or graphic image to be displayed.

That is, unlike the related art, in the present invention, instead of the polyhedron 110 including the display surface 112, the rotation axis 112 provided on both sides of the polyhedron 110 is connected to the driving element 200, And the driving element 200 is implemented as an electromagnet array in which magnetic dipoles 230a and 230b and 230'a and 230'b are arranged in an alternating arrangement so that the display surface 112 provided on the polyhedron 100 is formed, It is possible to precisely control the number of magnetic dipoles and the flip or rotation angle unit with respect to the display element according to the number of the display surfaces 112, thereby effectively increasing the number of colors that can be implemented .

On the other hand, in order to prevent the yarn area from being reduced in proportion to the display surface of the assembly module 1 as the thickness of the pair of plates 300 increases, the thickness of each of the pair of plates 300 needs to be minimized Since the electromagnet array mounted in the receiving groove 314 of the first plate 310 is not sufficiently covered with the thickness of the plate 300 but protrudes out of the surface when the thickness of the plate 300 is reduced, When the module 10 is formed of the assembly module 1 shown in Fig. 5, the electromagnet array may be interfered with, thereby making it difficult to closely arrange the module.

In order to solve this problem, a spacing flange 324 may be optionally provided on the second plate 320, as in the embodiment of the present invention. The spacing flange 324 may be formed in a manner such that when the flip-dot display device 10 of FIG. 1 is disposed adjacent to the flip-display device 10 in the transverse direction, An electromagnet array mounted in the receiving groove 314 of the first plate 310 is easily inserted into the corresponding space so as to secure a predetermined space 330 between the plate 310 and the second plate 320. [ The plurality of flip-display display elements 10 can be closely arranged in the lateral direction without interference by the electromagnet array even with a pair of plates 300 having the minimum thickness.

Further, it is preferable that the pair of plates 300 are provided in a rectangular shape so that the arrangement density of the assembly modules 1 is increased when the plurality of flip-display display elements 10 are arranged in the longitudinal direction .

5 is a perspective view showing a state in which a plurality of the flip-display display devices 10 are combined to form one assembly module 1. In FIG. As shown in the drawing, the assembling module 1 includes a flip-dot display device 10 which is extended in a lateral direction, a longitudinal direction, or both directions to form a display surface by adjoining the pair of plates 300 . Each of the display elements 10 may be configured to fix the plate 300 to the base using a commercially available fastening member such as a bolt with a base corresponding to a display surface size not shown in the figure as a support, The connection between the plates 300 can be performed using a commercially available fastening member such as a bolt, though it is not shown in the drawings.

The assembling module 1 can increase the arrangement density of the flip-display display element 10 by minimizing the weight of the warp area on the display surface by the shape of the pair of plates 300 and the coupling structure using the spacing flange 324 And the display element 100 and the driving element 200 are driven by the driving method and the shape of the display surface 112 of the display element 100 as described above, .

While the foregoing is directed to a specific embodiment of the present invention, it is to be understood that the above-described embodiment of the present invention has been disclosed for the purpose of illustration and is not to be construed as limiting the scope of the present invention, It should be understood that various changes and modifications may be made to the disclosed embodiments without departing from the spirit of the invention.

For example, in the embodiment, the polyhedron 110 of the display element 100 is illustrated as a hexahedron, but the present invention is not limited thereto, and the number of the display surfaces 112 in a state of being mounted between the pair of plates 300, 310, It can be added or subtracted depending on the number of colors. In this case, the number of magnetic dipoles constituting the electromagnet array as the driving element 200 and the unit of flip or rotation angle with respect to the display element 100 can be determined according to the number of display surfaces.

In the embodiment, the electromagnet array as the driving element 200 is received and mounted only on the first plate 310 of the pair of plates. However, the electromagnet array is also used as the driving element 200 on the other second plate 320 . In this case, it is necessary to synchronize the arrangement orientations of the electromagnet arrays accommodated in the first plate 310 and the second plate 320 with each other so that the directions of applied electromagnetic force in accordance with the application of the pulse current are mutually coincident.

Also, although the spacing flange 324 is illustrated as being provided on the second plate 320 in the embodiment, it is also possible to provide a spacing flange on the eleventh flange 310 on which the electromagnet array is mounted.
