Fig. 2 is a diagram showing a connection state in the bottom surface of Fig. 1
3 is a configuration diagram showing a display device according to another embodiment of the present invention

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention proposes a display device for displaying an image on a plurality of screens. The display device is connected to a small-sized mobile device such as the smart phone 10 and is used for extending the image.

According to the present invention, the main visual display unit 20 displaying image information by the control unit 26 is provided with a plurality of connection jacks 24 adjacent to the screen unit 21. The main viewer 20 has a screen portion 21 on the front surface of a rectangular or square frame. The screen unit 21 uses an LCD touch panel, and the side frame is formed of a thin plate of high strength. Although the connection jacks 24 are formed on both sides, they may be additionally formed on the upper and lower surfaces in consideration of expandability. The control unit 26 includes a microprocessor, a memory, and a microcomputer circuit having an input / output interface. An operation algorithm of the display device by the control unit 26 will be described later.

At this time, the main display device 20 is connected to a connection jack 14 of an external device such as the smart phone 10 and has a circuit for inputting and outputting signals. In addition, a battery and a charging circuit are mounted on the power source unit 22 in the main display device 20.

Further, according to the present invention, the screen expanding means for displaying the image information allocated in the main display device 20 is arranged to be adjacent to the main display device 20 in at least two directions. The screen expanding means displays the image information depending on the main display device (20) while enlarging the screen so as to be in close contact with the main display device (20).

Referring to FIG. 1, according to an embodiment of the present invention, the screen expanding means includes a first sub-picture changer 30 extending through connection jacks 34 to both sides of the main picture display device 20. The first sub-visual device 30 is the same as the main visual device 20 in that it has a screen portion 31, a power source portion 32, and a connection jack 24. [ However, the control section 26 of the main visual display device 20 can be excluded from the first auxiliary picture presenter 30. If a male type connection jack 24 is provided on the main display device 20, a female connection jack 24 is provided on the first auxiliary picture device 30. When the connection jacks 24 and 34 are coupled in a male and female structure, it is advantageous to maintain the mechanical coupling strength in addition to the electrical connection.

In this case, the main display device 20 outputs and displays the image set in the first auxiliary presenter 30 connected to the left and right sides.

3, according to another embodiment of the present invention, the screen expanding means further includes a second auxiliary picture changer 40 which is extended through a connection jack 44 on the side or upper and lower sides of the first auxiliary picture changer 30 The configuration is also possible. FIG. 1 shows a method of constructing three screens, whereas FIG. 3 shows a method of composing nine screens. It is possible to extend in a cross shape if the connection jacks 24 are provided in four directions of the main display device 20 and the connection jacks 34 are provided in four directions of the first auxiliary picture device 30. In this state, when the second auxiliary presenter 40 is connected to the four corner portions, nine screen configurations are completed.

The second auxiliary picture changer 40 includes a screen portion 41, a power source portion 42 and a connection jack 44 in the same manner as the first auxiliary picture device 30. However, it should be coordinated with the main visual display unit 20 and the first auxiliary visual display unit 30 in the configuration of the connection jack 44. If four male connection jacks 24 are provided in the main video camera 20 and four female connection jacks 34 are provided in the first auxiliary video surger 30, the second auxiliary video camera 40 is connected to four male connection jacks 44 ). Of course, the male and female connectors of the connection jacks 24, 34 and 44 may be arranged in different combinations.

According to this configuration, there is no restriction on the directionality of the coupling of the four first sub-picture devices 30 with respect to the main picture unit 20, and there is no restriction on the directionality of the coupling of the four second sub-picture devices 40. Since the connecting jacks 24, 34 and 44 of the main visual display unit 20, the first auxiliary visual display unit 30 and the second auxiliary visual display unit 40 are all combined in a male and female structure, the extended screen is prevented from being easily disturbed can do.

According to the detailed configuration of the present invention, the main visual viewer 20, the first auxiliary visualizer 30, and the second auxiliary visualizer 40 further include a plurality of electromagnets 50. The main image display device 20, the first and second sub-display devices 30 and 40 include electromagnets 50 in four directions to increase the cohesion of the extended screen. Of course, it is desirable to reduce electricity consumption by not operating a portion of the electromagnet 50 that is not required to be engaged according to the shape extending around the main image display device 20.

According to the detailed configuration of the present invention, the male connecting jacks 24, 34, and 44 provided in the main visual viewer 20, the first auxiliary visualizer 30, and the second auxiliary visualizer 40 have a drawable structure good. The male type connecting jacks 24, 34 and 44 are selectively provided according to the connection method of the main visual camera 20, the first auxiliary visualizer 30 and the second auxiliary visual device 40. [ In any case, if the male connection jacks 24, 34, and 44 are always exposed, there is a fear of inconvenience and a fear of damage. Therefore, a configuration in which the male connection jacks 24, 34, 44 are exposed or concealed by manual operation of a button (not shown) is preferred.

At this time, the main visual display unit 20, the first auxiliary visual display unit 30, and the second auxiliary visual display unit 40 have a separate side cover to protect the connection jacks 24, 34, 44, .

On the other hand, the main visual device 20, the first auxiliary visual device 30, and the second auxiliary visual device 40 can be connected in the same manner as the contact pads in place of the connection jacks 24, 34, In this case, the capacity of the electromagnet 50 is increased to maintain electrical connection and mechanical coupling strength.

1, when the user connects the first sub-picture presenter 30 to the left and right of the main picture presenter 20, the control section 26 is informed via the screen section 21 of the main picture presenter 20 of this state The control unit 26 generates signals in an external device such as the smartphone 10 as a three-split screen and displays them on three screens, respectively.

3, the user connects the first sub-picture presenter 30 to the top, bottom, left, and right sides of the main presenter 20, and then connects the first sub-picture presenter 30 to the second sub- The controller 26 generates a signal to be input from an external device into a 9-split screen and displays the signal in the form of a 9-split screen, if the controller 26 inputs this state to the controller 26 through the screen 21 of the main display device 20.

Of course, according to the basic principle of the present invention, it is possible to implement a modified example in which different screens are displayed by dividing and displaying a single unified information by altering the algorithm of the control unit 26.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
