In the case where the touch screen is electrostatic, the proximity sensor 141 can be configured to detect the proximity of the object with a change in the electric field along the proximity of the object having conductivity. In this case, the touch screen (or touch sensor) itself may be classified as a proximity sensor.

For the sake of convenience of explanation, the act of recognizing that an object is located on the touch screen while the object is not in contact with the touch screen is referred to as "proximity touch" Quot; contact touch ". The position at which an object is touched on the touch screen means a position at which the object corresponds vertically to the touch screen when the object is touched.

Meanwhile, the controller 180 can calculate the position of the wave generating source through the information sensed by the optical sensor and the plurality of ultrasonic sensors. The position of the wave source can be calculated by using the fact that the light is much faster than the ultrasonic wave, that is, the time when the light reaches the optical sensor is much faster than the time when the ultrasonic wave reaches the ultrasonic sensor. More specifically, the position of the wave generating source can be calculated using the time difference with the time when the ultrasonic wave reaches the reference signal.

More specifically, a photosensor mounts a photo diode and a transistor (TR) in a row / column and scans the contents placed on the photosensor using an electrical signal that changes according to the amount of light applied to the photo diode. That is, the photo sensor performs the coordinate calculation of the object to be sensed according to the amount of change of light, and the position information of the object to be sensed can be obtained through the calculation.

Thus, a combined image 157 as shown in FIG. 5 (c) can be formed, and the user can view the combined image of the first image 159-1 and the second image 159-2. In this case, the combined image 157 may be a stereoscopic image having a predetermined depth between the virtual image 156 of the first image 159-1 and the second image 159-2.

In this case, a driving unit for moving each display unit may be connected to one end of each of the first and second display units 151-1 and 151-2 connected to the controller 180. [ This will be described in FIGS. 12 to 13. FIG.

6, the first and second display units 151-1 and 151-2 are referred to as a control unit 180. However, the first and second display units 151-1 and 151-2 may be fixed or fixed. May be a housing for supporting. Accordingly, the control unit 180 is disposed in the housing, and the first and second display units 151-1 and 151-2 can be electrically connected to the control unit 180 through the opening 198 formed in the housing. The same is applied hereinafter.

Meanwhile, the half mirror 155 may be formed between the first display unit 151-1 and the second display unit 151-2. Specifically, when the first display unit 151-1 is located at the lowermost end, the half mirror 155 may contact one end of the first display unit 151-1 connected to the controller 180. [ In this case, the first display unit 151-1 and the half mirror 155 can form an angle of 45 degrees. Also, since the first and second display units 151-1 and 151-2 are formed perpendicular to each other, the second display unit 151-2 and the half mirror 155 can also form an angle of 45 degrees.

On the other hand, the vertical lengths L1 and L2 of the first and second display units 151-1 and 151-2 may be equal to each other. The half mirror 155 forms an angle of 45 degrees with the first and second display units 151-1 and 151-2 at a position in contact with the control unit 180. [ The length L3 of the half mirror 155 may be √2 times the lengths L1 and L2 of the first and second display portions 151-1 and 151-2 in the cross section in the longitudinal direction .

Specifically, in comparison with FIG. 6, the first display portion 151-1 has been moved a / 2 away from the uppermost portion of the three-dimensional image display device 100. FIG. In this case, since the half mirror 155 is fixed, the virtual image 156 of the first image 159-1 can be formed at a point P2 that has been moved backward by a / 2 in the backward direction from P1. Thus, if the second display portion 151-2 does not move, the depth between the virtual image 156 of the first image 159-1 and the second image may be d2, which is less than d1. The combined image 157 when the depth is d2 is as shown in the bottom of Fig.

Consequently, the controller 180 may reduce the depth between the virtual image 156 and the second image for the first image 159-1 by moving the first display unit 151-1 in the upward direction. Conversely, the control unit 180 may increase the depth between the virtual image 156 and the second image for the first image 159-1 by moving the first display unit 151-1 in the downward direction.

Referring to FIG. 8, the second display unit 151-2 moves in the front direction. 6, the second display portion 151-2 is moved away from the rear end of the three-dimensional image display device 100 by 2b. In this case, since the first display unit 151-1 does not move and the half mirror 155 is fixed, the virtual image 156 of the first image 159-1 can be formed at the point P1. Thus, the depth between the virtual image 156 of the first image and the second image may be d3, which is less than d1. The combined image 157 when the depth is d3 is as shown in the bottom of Fig.

Consequently, the controller 180 can reduce the depth between the virtual image 156 and the second image for the first image 1) by moving the second display portion 151-2 in the front direction. Conversely, the control unit 180 may increase the depth between the virtual image 156 and the second image for the first image by moving the second display unit 151-2 in the rear direction.

On the other hand, as described above, the half mirror 155 can be formed longer than the first display unit 151-1. Therefore, as shown in FIG. 19 (b), a groove for containing the half mirror 155 may be formed on each of the surfaces of the first and second cases 195-1 and 195-2 that are in contact with each other.

Therefore, according to the three-dimensional image display apparatus 100B according to yet another embodiment of the present invention, since the first and second display units 151-1 and 151-2 can be folded, the portability and storage property are increased . In addition, since the case is formed, the external impact can be alleviated.

20 is an example of a cross-sectional view of a three-dimensional image display device 100C according to another embodiment of the present invention. Hereinafter, the description of the parts overlapping with the above description will be omitted.

20, a three-dimensional image display apparatus 100C according to another embodiment of the present invention includes first to third display units 151-5 to 151-7, a half mirror 155, a controller 180 ).

The first to third display units 151-5 to 151-7 display the first to third images, respectively. In this case, the first and second display units 151-5 and 151-6 are formed to face each other and may be respectively disposed on the upper and lower surfaces of the three-dimensional image display device 100C. The first and second display portions 151-5 and 151-6 are preferably formed to have the same size.

Meanwhile, the third display unit 151-7 is formed to be perpendicular to the first and second display units 151-5 and 151-6, and may be disposed on the rear surface of the three-dimensional image display device 100C. In particular, the vertical length of the third display portion 151-7 may be twice the vertical length of the first and second display portions 151-5 and 151-6.

On the other hand, as shown in FIG. 20, the half mirror 155 may have two surfaces perpendicular to each other. Specifically, the half mirror 155 has a first surface and a second surface formed between the first display portion 151-5 and the third display portion 151-7 at an angle of 45 degrees, And a second surface formed at an angle of 45 degrees between the display portions 151-7. It is to be noted that the cross-sectional length of the half mirror 155 with respect to the first and second surfaces may be √2 times the cross-sectional length of the first and second display portions 151-5 and 151-6 as described above .

20, since the first display unit 151-5 for displaying the first image is formed on the upper surface of the three-dimensional image display device 100C, the first image is displayed on the three-dimensional image display device 100C ) From the upper side to the lower side. In this case, the first surface of the half mirror 155 can switch the direction in which the first image is displayed. Therefore, the first image displayed in the lower side direction can be displayed in the rear direction by the first side of the half mirror 155. In this case, the image passed through the half mirror 155 may be the first virtual image 156-1. Therefore, the first virtual image 156-1 can be spaced apart from the third image displayed by the third display portion 151-7 by a predetermined distance, and can be displayed in the same direction as the third image.

Similarly, since the second display portion 151-6 for displaying the second image is formed on the lower side of the three-dimensional image display device 100C, the second image is displayed on the lower side of the three-dimensional image display device 100C Is displayed in the upper side direction. In this case, the second surface of the half mirror 155 can switch the direction in which the second image is displayed. The second image displayed in the upper side direction can be displayed in the rear direction by the second side of the half mirror 155. [ In this case, the image passed through the half mirror 155 may be the second virtual image 156-2. Accordingly, the second virtual image 156-2 can be spaced apart from the third image displayed by the third display portion 151-7 by a predetermined distance, and can be displayed in the same direction as the third image.

Accordingly, the user can view the combined image of the first to third images. More precisely, the user can combine the first virtual image 156-1 with the first depth into one region of the third image, and the second virtual image 156-2 with the second depth into another region of the third image, The user can view a combined three-dimensional image.

In the above description, the cross-sectional view of the three-dimensional image display device 100C shown in FIG. 20 is a longitudinal sectional view, but the present invention is not limited thereto. Accordingly, the controller 180 may control the first and second images to be formed at a predetermined distance from the left end and the right end of the third image, respectively.

On the other hand, the half mirror 155 may be integrally formed, and the first and second half mirrors 155-1 and 155-2 may be in contact with one side of each.

On the other hand, as each of the first to third display units 151-5 to 151-7 moves, the depth between the first virtual image 156-1 and the third image, or the depth between the second virtual image 156-2 and the third image 156-2, The depth may be changed. Also, the first to third driving units may be formed to move the first to third display units 151-5 to 151-7, respectively. Further, each of the first to third display units 151-5 to 151-7 is implemented as a screen, so that the content, the shot image, and the like can be displayed by the projection of the projector as described above.
