[0001] Flip Dot Display Element and Assembly Module [0002]

The present invention relates to a flip-dot display device, and more particularly, to a flip-dot display device in which a magnetic flux is generated in accordance with the flow of a current by flowing a current through a coil and facilitates the action of the electromagnetic force by the magnetic flux, Dot display device and its assembly module capable of displaying a unit image by rotating the flip-dot display device.

Generally, a device for displaying an image is a device for outputting information to an image using a screen. One of the computer output devices is a common monitor. Most of the output data is represented by characters, symbols, figures, images, sounds, and the like. All of the data except the voice is visual, and the video display device is a device that temporarily displays this information on the screen. A typical image display device is a CRT (Cathode Ray Tube). It is a method using a general monitor or a TV picture tube, in which a light is emitted by an electron gun on the screen, and a character or an image is displayed by emitting light according to a phosphor on a cathode ray tube. In addition, there are LCD (liquid crystal display), TFT-LCD (thin film liquid crystal display), PDP (plasma display), flexible display and HMD (head mounted display). HMD is a next-generation image display device that can be worn on a head like a pair of glasses and can be used as a large-screen image or as a surgical or diagnostic medical device. Compared to other output devices such as printers, there is no noise at the output and the speed is very fast. It saves money because paper is not used, but it can not be stored in the form of documents.

The apparatus for displaying such images has many limitations in terms of enlargement. A typical large-size electric signboard displays various images by arranging many LEDs in module form. However, the billboard has a disadvantage of high production cost, high power consumption, and large heat generation. In addition, the electric signboard has a disadvantage in that it is disadvantageous in terms of expandability in addition to a predetermined size.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of a flip-dot display device and an assembly module thereof according to the present invention will be described in detail with reference to the accompanying drawings.

1A and 1B, the operation principle of the flip-dot display device is such that first vertical pawl 1a and second vertical pawl 1b in a substantially vertical direction are bent and connected to a horizontal pawl 1c in a substantially horizontal direction The electromagnetic member 1 is provided and the coil 2 is wound around the outer periphery of the first vertical pole 1a and the second vertical pole 1b and the first vertical pole 1a and the second vertical pole 1b A flip disk 4 having a surface coated with magnet on one side to which a horizontal rotary shaft 3 is coupled is positioned. Here, when a current is passed through the coil 2, which is an enamel coated wire, the first vertical pole 1a and the second vertical pole 1b are magnetized to the N pole or the S pole by the current flowing through the coil 2, respectively. The flip disk 4 is coated with a magnetic material on one side. Therefore, the first vertical pole 1a and the second vertical pole 1b are magnetized to the N pole or the S pole according to the direction of the current flowing through the coil 2, so that the first vertical pole 1a and the second vertical pole 1b, The flip disk 4 positioned between the flip-flops 1b is stopped or rotated 180 degrees according to a predetermined polarity.

1A, when a forward pulse current (set) is supplied to the coil 2, the first vertical pole 1a becomes an S pole and the second vertical pole 1b becomes an N pole. At this time, if the left side of the flip disk 4 is the N pole and the right side is the S pole, an attractive force acts between the S pole of the first vertical pole 1a and the N pole of the flip disk 4, And the S pole of the flip disk 4, as shown in Fig. Thus, the flip disk 4 is rotated about the rotation axis 3 so that one side of the flip disk 4, that is, the plane is directed upward.

1B, when a reverse pulse current (reset) is supplied to the coil 2, the first vertical pole 1a becomes an N pole and the second vertical pole 1b becomes an S pole. At this time, if the left side of the flip disk 4 is the S pole and the right side is the S pole, attraction is exerted between the S pole of the first vertical pole 1a and the N pole of the flip disk 4, And the S pole of the flip disk 4, as shown in Fig. Therefore, the flip disk 4 is rotated around the rotating shaft 3 so that one surface of the flip disk 4, that is, the bottom surface faces upward.

The flip disk 4 keeps its current state until a reverse pulse current or a forward pulse current is applied to the electromagnetic member 1 so that the plane and the bottom face are switched in a plane or a bottom face facing upward.

In addition, FIG. 1C operates on the same operating principle as FIGS. 1A and 1B, and is preferably applied when the diameter of the flip disk is relatively large. A flip disk 1 in which a rod-like electromagnetic member 1 is vertically disposed, a coil 2 is wound around the outer periphery of the electromagnetic member 1, and a surface of the rotating shaft 3 is magnetically coated on the electromagnetic member 1, (4). Here, when a current is passed through the coil 2, the upper and lower portions of the electromagnetic member 1 are magnetized to the S-pole or the N-pole, respectively. When the electromagnetic member 1 is magnetized, an attractive force or a repulsive force acts on the flip disk 4 close to the upper portion of the electromagnetic member 1. The attractive force or repulsive force of the flip disk 4 acts on the polarity of the electromagnetic member 1 depending on the direction of the current applied to the coil 2 so that the rotation of the rotary shaft 3 causes the flip disk 4 to rotate in a plane Or the bottom surface faces upward.

According to the above-mentioned working principle, the flip disk is rotated by the polarity change of the magnetized electromagnetic member in accordance with the direction of the applied current, so that the flat surface or the bottom surface faces upward. Also, if the color of the plane and bottom of the flip disk is different, the unit image can be expressed by acting as two changing pixels.
