However, the following embodiments are provided to those skilled in the art to fully understand the present invention, and may be modified in various forms, and the scope of the present invention is limited to the embodiments described below. It doesn't happen.

FIG. 2 is a diagram schematically illustrating an external appearance of an information input / output device for displaying vibration and three-dimensional stereograms according to an exemplary embodiment of the present invention. Referring to FIG. 2, an information input / output device for displaying vibrations and three-dimensional stereoscopic images according to the present invention is typically disposed in an area where a display such as an LCD is located, and the information input / output device includes a plurality of pixels 100. have. The number of pixels may vary depending on the size of the information input / output device according to the present invention, and the size of one pixel may be several mm or less depending on the manufacturing method.

3A to 3C illustrate an example in which some pixels of an information input / output device for displaying vibration and three-dimensional stereoscopic image are raised vertically to display information according to an exemplary embodiment of the present invention. The height at which the individual pixels rise vertically can be changed according to the content of information to be displayed, and three-dimensional stereoscopic display can be performed by combining a plurality of pixels.

Hereinafter, with reference to the drawings will be described a specific configuration and operation principle of the pixel shown in Figs.

4 is a side view of one pixel 100 of an information input / output device for displaying vibration and three-dimensional stereograms according to an exemplary embodiment of the present invention. As shown in FIG. 4, the pixel includes an outer cover 200, an inner pillar 210, an upper substrate 220, and a lower substrate 230. Among these, the outer cover 200 and the inner pillar 210 portion 110 represent the height of the pixel, and the upper substrate 220 and the lower substrate 230 portion 120 are in front, rear, left, and right sides or in a circular shape. This part expresses vibration.

FIG. 5 illustrates an example in which the height is changed in one pixel of an information input / output device displaying vibration and three-dimensional stereograms according to an embodiment of the present invention. Referring to FIG. 5B, the outer cover 200 and It can be seen that the height of the pixel is higher than that of FIG. 5A due to the operation of the inner pillar 210.

FIG. 6 illustrates an example in which left and right positions are changed in one pixel of an information input / output device displaying vibrations and three-dimensional stereograms according to an embodiment of the present invention. Referring to FIGS. It can be seen that the left and right positions of the substrate 220 and the lower substrate 230 are moved with each other.

Hereinafter, the vertical vertical movement of the pixel will be described in more detail with reference to FIGS. 7 and 8.

7 is a view for explaining an embodiment of the configuration of the outer cover 200 and the inner pillar 210 of the pixel. Referring to FIG. 7, four permanent magnets 310, 311, 312, and 313 are disposed on the outer cover 200, and pairs with permanent magnets 310, 311, 312 and 313 on the inner column 210. Four electromagnets 300, 301, 302, and 303 are formed. According to the embodiment, the electromagnet may be disposed on the outer cover 200 and the permanent magnet may be disposed on the inner pillar 210, and the number of paired electromagnets and permanent magnets may be four or less.

Specifically, four electromagnets 300, 301, 302, and 303 are disposed on the inner pillar 210 according to height, and four permanent magnets 310, 311, 312, and 313 disposed on the outer cover 200 are electromagnets. Paired with, but not at the same height as the electromagnet. Since the electromagnet becomes magnetic only when a current is supplied, it is possible to vary the height of the pixel by supplying current to each electromagnet individually. That is, when a current is supplied to one electromagnet, the outer cover 200 is vertically moved up and down since interaction with the permanent magnet paired thereto, that is, attraction is generated and attracted.

8 (a) to 8 (c) show the vertical movement of the pixel. In FIG. 8 (a), only the electromagnet 302 in FIG. 7 is energized and activated. Accordingly, the permanent magnet 312 which is the closest pair to the electromagnet 302 is fixed close to the electromagnet 302. 8B and 8C show a case in which the electromagnet 303 is activated while the electromagnet 302 is deactivated. As the electromagnet 303 is activated as described above, the permanent magnet 313, which is a pair nearby, is attracted, and the pixel moves one step down. 8 (c) shows that the electromagnet 303 is activated to completely attract the permanent magnet 313 to maintain a constant height of the pixel.

As the height is moved, the positions of the electromagnets and the permanent magnets are set so that each electromagnet can easily attract each pair of permanent magnets. For example, when the electromagnet 302 and the permanent magnet 312 are attached, the permanent magnet 313 is slightly above the electromagnet 303, and the permanent magnet 311 is slightly below the electromagnet 301 in advance. It can be designed by adjusting. Or by adjusting the interval and the number of paired electromagnets and permanent magnets it is possible to adjust the height of the pixel in more detail and variety. That is, by sequentially supplying current to the electromagnet of the inner pillar, the outer cover can be vertically moved in step by interaction with the permanent magnet paired with the electromagnet supplied with the current.

Furthermore, one pixel 100 of the information input / output device displaying the vibration and the three-dimensional stereoscopic display according to the present invention can sense a user's input. When the user presses the pixel, the height of the pixel is changed so that the minute flows through the internal electromagnet. The magnitude of the current will change. By measuring this, the degree of depression of the current pixel can be measured and can be received as a user input.

Hereinafter, the horizontal movement of the pixel will be described in more detail with reference to FIGS. 9 and 10.

9 is a diagram for describing an exemplary embodiment of a configuration of an upper substrate and a lower substrate of a pixel. Referring to FIG. 9, four permanent magnets 314, 315, 316 and 317 are disposed on the upper substrate 220, and a pair of permanent magnets 314, 315, 316 and 317 are disposed on the lower substrate 230. Four electromagnets 304, 305, 306, and 307 are formed. According to the embodiment, the electromagnet may be disposed on the upper substrate 220 and the permanent magnet may be disposed on the lower substrate 230, and the number of paired electromagnets and the permanent magnets may be four depending on the shape of the upper substrate and the lower substrate. It may be less or more.

In detail, the lower substrate 230 and the upper substrate 220 have a rectangular plate shape, and four electromagnets 304, 305, 306, and 307 and permanent magnets 314, 315, 316, and 317 are paired on four surfaces. Since the lower substrate 230 and the upper substrate 220 are different in size, the positions of the permanent magnet and the electromagnet are shifted. However, since the electromagnet becomes magnetic only when a current is supplied, the left and right positions of the pixel may be changed by moving the upper substrate 220 by supplying current to each electromagnet individually. That is, when a current is supplied to an electromagnet of the lower substrate in a state in which the lower substrate 230 is fixed, the upper substrate 220 moves together because the permanent magnet and the attraction force are generated and attracted. Therefore, it is preferable that the upper substrate and the lower substrate are stacked to be movable with each other.

10 (a) to 10 (c) illustrate the left and right movement of the pixel. In FIG. 10 (a), only the electromagnet 307 is supplied with an electric current to activate the pixel. Therefore, the permanent magnet 317 in the position closest to the electromagnet 307 is attracted and fixed to the electromagnet 307.

10 (b) and (c) show that the electromagnet 305 is activated while the electromagnet 307 is deactivated. When the electromagnet 305 is deactivated and the electromagnet 305 is activated, an attraction force is generated between the electromagnet 305 and the permanent magnet 315, so that the upper substrate 220 and the outer cover 200 and the inner pillar 210 installed thereon. Will move to the right. 10 (c) shows that the upper substrate 220 thus moved is completely fixed to the right.

As described above, since various types of movements can be generated according to the order and combination of activating the electromagnets 304, 305, 306, and 307 of FIG. 9, the user may feel it as a vibration. For example, if the electromagnet 307 and the electromagnet 305 of FIG. 9 are alternately activated, the pixel may vibrate left and right. If the electromagnet 304 and the electromagnet 306 of FIG. 9 are alternately activated, the pixel vibrates back and forth. Can be expressed. Alternatively, if the electromagnets 304, 305, 306, 307 are activated sequentially, they may exhibit vibrations that rotate in the counterclockwise direction.
