Referring to FIGS. 1 to 3, a dual display apparatus 100 according to an exemplary embodiment of the present invention includes a first display unit 110, a second display unit 120, and a controller 130.

The first display unit 110 is a transparent display panel that uses a user's touch input as an input pointer. The first display unit 110 is provided at the front end of the dual display device 100 and is formed in a transparent state by using a transparent thin film transistor or a transparent active organic light emitting diode. Further, the first display unit 110 may be controlled to be converted into an opaque screen by the operation of the observer P. The first display unit 110 may provide various functions on a screen through a user interface (UI) of various applications. The first display unit 110 displays images such as programs, files, and operation options. Examples of images used here include a window, a field, a dialog box, a menu, an icon, a button, a cursor, a scroll bar, And the like. The user can select the image and activate various functions associated with the selected image. For example, the user can select a button for opening, closing, minimizing, or maximizing a window, or an icon for activating a specific program. On the first display unit 110, the movement of the input pointer is made by a user's finger or a touch pen.

In the second display unit 120, a part or the entire area of the second display unit 120 provided at the lower end of the dual display device 100 is overlapped with the first display unit 110 to be overlapped Screen is provided. The second display unit 120 may be formed to be transparent as in the first display unit 110, according to an embodiment of the present invention.

The second display unit 120 may provide various functions on the screen through a user interface (UI) of various applications. The second display unit 120 displays images such as programs, files, and operation options. Examples of images used here include a window, a field, a dialog box, a menu, an icon, a button, a cursor, a scroll bar, And the like. The user can select the image and activate various functions associated with the selected image. For example, the user can select a button for opening, closing, minimizing, or maximizing a window, or an icon for activating a specific program. On the second display unit 120, the movement of the input pointer is made by a user's finger or a touch pen.

When the user touches the first display unit 110, the second display unit 120 outputs an image according to a corresponding coordinate value. That is, when the first image outputted from the first display unit 110 or the second image outputted from the second display unit 120 is touched or moved along the surface of the first display unit 110, And corresponds to the relative movement of the finger or the touch pen.

The control unit 130 senses a touch input generated from the first display unit 110. In addition, the first display unit 110 and the second display unit 120 may be controlled to output an image, and the output image may be displayed on the second display unit or the second display unit, To the first display unit. Here, the image output from the first display unit 110 is referred to as a first image, and the image output from the second display unit 120 is referred to as a second image. The first image and the second image may include a UI, content, a photograph, an image, and the like. The first image displayed on the first display unit 110 can be viewed through the first display unit 110. [ In addition, since the first display unit 110 is a transparent panel, the viewer P can see through the first display unit 110. FIG. Therefore, the observer P can view the second image outputted from the second display unit 120 located at the rear end of the first display unit 110 through the first display unit. The observer P can touch input the first image outputted to the first display unit 110 and touch the specific region of the first display unit having the coordinate value corresponding to the second image . According to the touch input, the controller 130 may move the second image output from the second display unit 120 to the first display unit 110. That is, the first display unit 110 outputs a second image, which is output to the second display unit 120 through the first display unit 110, to the first display unit 110. At this time, the size, arrangement, or sharpness of the image may be changed at the same time as moving from the second display unit 120 to the first display unit 110. For example, when the image is output to the second display unit 120, the image is blurred and small. However, when the image is output to the first display unit 110, the image may be changed to a clear and large image.

The display 140 may be positioned between the first display unit 110 and the second display unit 120 and may be positioned between the first display unit 110 and the second display unit 120, And the second image outputted from the second unit 120 can be observed. At this time, the first display unit 110 and the second display unit 120 may output a related image of the display 140. FIG. The first image displayed on the first display unit 110 through the first display unit 110 and the display 140 are displayed on the second display unit 120, The second image can be observed in this order. Therefore, the observer P can acquire intuitive information accompanied by stereoscopic and interesting stimulation of the display 140 through the dual display device 100 according to the present invention. Further, the observer P observing the dual display device 100 according to the present invention may be moved and observed without observing it in place. Therefore, it is necessary to flexibly change the output position of the images output from the display units 110 and 120 according to the movement of the observer P. When considering the position of the observer P in order to capture the motion of the observer P, a face tracking technique can be applied. That is, the face of the observer P can be traced to determine the position. For example, there is a method of tracking the location of the facial or facial organs in an image using a certain search strategy based on image features (e.g., color, grayscale histogram, edge shape, etc.). In addition, the position of the image output from the first and second display units 110 and 120 may be determined by tracking the line of sight of the observer P. [

Hereinafter, the operation of the dual display apparatus according to another embodiment of the present invention will be described.

4 is a view of a dual display device according to another embodiment of the present invention.

4, images output to the first display unit 110 and the second display unit 120 are respectively set in a predetermined hierarchy. The first display unit 110 and the second display unit 120 are already set in layers 1 to 3. For example, end point a is a photograph of 1910s history, end point b is a photograph of 1930s history, and end point c is a photograph of 1950s history. The end point a corresponds to the layer 1, the end point b corresponds to the layer 2, and the end point c corresponds to the layer 3. At this time, when the observer P touches and scrolls a predetermined image T output from the first display unit 110 and drags to the end point a, among the second images output to the second display unit, The corresponding images 1a and 1b are moved to the first display unit 110. FIG. On the other hand, if the image corresponding to the layer 1 is already output to the first display unit 110, the movement is not performed. At the same time, if images corresponding to the layer 2 and the layer 3 are output to the first display unit 110, the images 2a and 2b corresponding to the layer 2 and the images 3a and 3b corresponding to the layer 3, The second display unit 120, and the second display unit 120, respectively.

If the observer P touches and scrolls the predetermined image T again to the end point b, the images of the layer 1 outputted to the first display unit 110 are displayed on the second And moves to the display unit 120. At the same time, all the layers 2 images 2a and 2b outputted to the second display unit 120 are moved to the first display unit 110. The above function is not limited to the touch scroll but may be operated according to various inputs by the operation of the observer P. [

Hereinafter, the structure and operation of a dual display device according to another embodiment of the present invention will be described.

5 and 6 are views of a dual display device according to another embodiment of the present invention.

Referring to FIGS. 5 and 6, it can be seen that the first image output from the first display unit 110 and the second image output from the second display unit 120 are output as circular trajectories. Referring to FIG. 5, the control unit is designed in software to output an image to the display units 110 and 120. FIG. 6 is a block diagram of the first display unit 110 and the second display unit 52, and 53 and the second images 54, 55, and 56 output from the first and second images 120 and 120, respectively. More specifically, the controller 130 controls the operation of the observer P so that the first images 51, 52 and 53 output from the first display unit 110 and the second images 51 and 52 output from the second display unit 120, The images 54,55, 56 may be rotated and moved in a circular path with respect to each other. In this case, the operation of the observer P may be an operation by the touch drag of the first display unit 110, and the first image 51, 52, And the second images 54, 55, and 56 can be rotated and moved in a circular trajectory with respect to each other. That is, if the observer P touch-drages the first display unit 110 in the leftward direction, the second images 54, 55, and 56 output from the second display unit 120 rotate in a clockwise direction And moves to the first display unit 110 while being rotated. At the same time, the first images 51, 52, and 53 output from the first display unit 110 by the moved distance move while rotating along the circular trajectory in the clockwise direction to the second display unit 120. At this time, if the observer P performs the touch dragging at a high speed, the second images 54, 55, and 56 are rotated and moved to the first display unit 110 more than when the touch dragging is performed at a slow speed. For example, if the first image 51 is rotated and moved to the second display unit 120 while the second image 54 is rotated and moved to the first display unit 110, the first image 51 is moved to the second display unit 120. However, if the second image 54,55 is rotated by the first display unit 110 while the second image 54,55 is moved at the speed 2, the first image 51,52 is rotated by the second display unit 120, do. It is assumed that the speed 1 and the speed 2 are values for explaining the relative speed, and the speed 2 is a speed two times the speed 1. In addition, if the observer P touch-drages to the right, the first images 51, 52, and 53 output from the first display unit 110 move to the second display unit 120 while being rotated counterclockwise . At the same time, the second images 54, 55, and 56 outputted from the second display unit 120 by the moved distance are also moved to the first display unit 110 with a circular trajectory in the counterclockwise direction.

Hereinafter, a method of moving images output from the first display unit and the second display unit at different moving speeds will be described.

7 to 10 are views for explaining a method of moving images at different speeds on a screen of a dual display device according to the present invention. 7 is an output screen of the first display unit before touch dragging. 8 is an output screen of the first display unit after the touch drag. 9 is an output screen of the second display unit before the touch dragging. 10 is an output screen of the second display unit after the touch drag.

7 to 10, when the first images 51 to 53 output from the first display unit 110 and the second images 53 to 59 output from the second display unit 120 are at different speeds . ≪ / RTI > 7 to 10 are based on moving the first image and the second image while rotating in a circular trajectory as described above.

As the observer P touch-drages the first display unit 110 to the left, the first images 51 to 53 move to the left. Also, it can be seen that the second image 54 before the touch dragging moves to the first display unit 110. At this time, the movement is shifted by 1/2 of the horizontal length of the output screen of the first display unit 110. That is, 53 was output in the center of the first display unit 110 instead of 52. 9 and 10, an output screen of the second display unit 120 at the same time as the above process is performed. 59 is displayed on the leftmost side of the second display unit 120 before the observer P performs the touch dragging. However, as the touch dragging of the observer P progresses, 59 is displayed on the rightmost side of the second display unit 120 As shown in FIG. If the first display unit 110 is moved at the same speed as the first display unit 110, 59 is to be output in the middle of the second display unit 120 according to the touch drag, Which is the leftmost to the rightmost of the output screen. Therefore, when the observer P moves the images through the touch dragging, the first image outputted from the first display unit 110 at the front end of the display device 100 is moved little by little, The second image outputted from the second display unit 120 is moved quickly. However, the present invention is not limited to the movement of the first display unit 110 and the second display unit 110, The first image and the second images output from the image processing unit 120 may move at different speeds. That is, the speed at which the first image outputted from the first display unit 110 moves to the second display unit 120 and the second image outputted from the second display unit 120 are transmitted to the first display unit 120, So that the speed of movement to the moving body 110 can be controlled to be different. Also, the first display unit 110 can move at a different speed between a plurality of first images output from the first display unit 10. Also, the second display unit 120 can move at a different speed between a plurality of second images output from the second display unit 120.

Hereinafter, a touch recognition method for a portion where images outputted from the first display unit and the second display unit overlap is described.

11 is a view for explaining a touch recognition method in a superimposed area between display portions of a dual display device according to the present invention. 12 to 16 illustrate a touch recognition method of a superimposed area between display portions of a dual display device according to the present invention.

11, the first image 111 output from the first display unit 110 and the second image 121 output from the second display unit 120 are overlapped with each other when viewed by the observer P, have. The controller 130 processes the coordinate values of the images 111 and 121 output from the first display unit 110 and the second display unit 120. The controller 130 recognizes the coordinate values of the images 111 and 121 that are displayed on the screens of the display units 110 and 120. The control unit 130 can recognize the area where the touch input is generated in the first display unit 110 and can recognize the area where the touch input is performed in the first display unit 110, As shown in Fig. That is, when the observer P touches the first image 111 output from the first display unit 110, the control unit overlaps the second image 121 output from the second display unit 120 And may selectively activate the first image 111 and the second image 121. [

FIG. 12 shows an initial state in which the first image 111 is activated, and FIG. 13 shows a state in which the second image 121 is activated. The first image 111 and the second image 121 may be selectively activated according to the number of touches. That is, when the observer P touches the first image 121 of the first display unit 110, the controller 130 displays the first image 111 output from the first display unit 110 at the initial touch, And activates the second image 121 output from the second display unit 120 in a subsequent touch operation.

In addition, the first image 111 and the second image 121 can be selectively activated by the touch time. That is, when the observer P touches the first image 111 of the first display unit 110, the controller 130 displays the first image 111 output from the first display unit 110 at the initial touch, To activate it. At this time, if the touch input is maintained at a predetermined reference time or longer, the second image 121 output from the second display unit 120 is activated.

The first image 111 may be touched by the second display unit 120 and the second image may be displayed by touching a predetermined image 112 located at another touch contact output from the first display unit 110. [ The second image 121 may be switched to the first display unit 110 to activate the second image 121. 14, when the observer P touches the first image 111 of the first display unit 110, the controller 130 displays the first image 111 on the first display unit 110 at the initial touch, The first image 111 is selected and activated. Then, referring to FIG. 15, a predetermined image 112 located at another touch contact output from the first display unit 110 is touched. Referring to FIG. 16, the second image 121 is switched to the first display unit 110, and the second image 121 is activated. With this selective activation, the observer P can flexibly operate in selecting the image of the region where the first display unit 110 and the second display unit 120 overlap.

Hereinafter, a method of selecting a menu through touch recognition in the display unit of the dual display apparatus according to the present invention will be described.

17 to 18 are views for explaining a method of selecting a menu through touch recognition in the display unit of the dual display device according to the present invention.

17 to 18, the menus (A, B, C, D, E, and F) output from the first display unit 110 exist in a circular trajectory over the second display unit 120. B2, b3, b4, b5, b6, b3, b4, b5, b6 exist in the menus A, B, C, D, b6) may be configured to include another submenu. In this way, the observer P is inconvenient to touch several times in order to select a desired menu. In order to solve this problem, the controller 130 recognizes that the touch input on the first display unit 110 is maintained over a predetermined reference time. Thereafter, a first image corresponding to the touch input or a sub menu of the second image is output. Then, when the observer P drags while maintaining the touch input, it controls the submenu to move based on the drag. Specifically, when the observer P among the menus A, B, C, D, E, and F in FIG. 15 maintains the touch input with the menu 2 (B) And the submenus (b1, b2, b3, b4, b5, b6) of the menu 2 (B) are outputted. Thereafter, it is possible to select any one of the submenus (b1, b2, b3, b4, b5, b6) by dragging by touching at least a predetermined reference time without touching again. 6, the submenu may be configured to be output so as to be deformed while maintaining its original shape.

Hereinafter, a dual display device according to another embodiment of the present invention will be described. 19 is a view showing a state of the first image outputted from the first display unit. 20 is a view showing a state of the second image outputted from the second display unit. 21 is a view showing a state in which the first display unit and the second display unit are viewed at the same time.

19 and 20, the first display unit 110 outputs first images A1 to A14 having a circular trajectory, and the second display unit 120 outputs second images A1 to A14 having a circular trajectory, And outputs images B1 to B10. Referring to FIG. 21, when the observer P looks at, the first images A1 to A14 and the second images B1 to B10 can be simultaneously viewed. At this time, the lower part of B1 can be overlapped with the upper part of A1 and output. However, in this case, when the observer P looks at the transparency of A1, the lower part of B1 overlapped can be seen through A1. Also, in the case of overlapping in A2 and B2, A14 and B10, the overlapping B2 and B10 can be seen by adjusting the transparency of A2 and A14. It is also possible to output A7, A8 and A9 at the top of B5, B6 and B7 so that they do not overlap when viewed by the observer P and B1 is outputted at the top of A1 so that A1 and B2 described above do not overlap You may.

A7, A8, and A9 having relatively high output positions on the first display unit 110 among the first images A1 to A14 are output more transparently than A1, A2, and A14 with relatively low output positions. Among A7, A8, and A9, A8 having a relatively higher output position is more transparent than A7 and A9. However, the degrees of transparency are the same for A7 and A9 where the output positions are the same. In addition, not only the transparency but also the first images A1 to A14 output on the first display unit 110 may be output with different brightness, size, and / or saturation depending on the output position. For example, the first images A1, A2, and A14 with relatively low output positions can be output larger than the first images A7, A8, and A9 with relatively high output positions, and among A7, A8, and A9 A8 having the highest output position is output in the smallest size. Since A7 and A9 have the same output position height, they are larger than the A8 and can output the same size. The second display unit 120 may output at least one of transparency, lightness, size, and chroma of the second images B1 to B10 differently according to the output position as in the first display unit.

In addition, the first images A1 to A14 and the second images B1 to B10 can be rotated along a circular trajectory by a user operation, and the first images A1 to A14 and The second images B1 to B10 can be moved to each other. That is, the second images B1 to B10 are moved to the first display unit 110 and the first images A1 to A14 are moved to the second display unit 120. Here, the user operation may be a touch input.

When the observer P touches any one of the first images A1 to A14 output to the first display unit 110, the second image, which is a circular trajectory output to the second display unit 120 B1 to B10 may be converted into submenus corresponding to any one of the first images A1 to A14 touched by the observer P. [

As described above, the dual display device according to the exemplary embodiment of the present invention is not limited to the configuration and method of the embodiments described above, but the embodiments may be modified so that various modifications may be made. All or some of them may be selectively combined.
