3 is a view for explaining the principle of a three-dimensional image display method using binocular parallax according to an embodiment of the present invention.

Methods of displaying a 3D image may be classified into a stereoscopic 3D display requiring glasses and an autostereoscopic 3D display using glasses-free binocular parallax. The glasses-free display is the same as the glasses type in terms of giving a three-dimensional effect by using binocular disparity, but is differentiated in that no special glasses are required. One of the principles of the glasses-free 3D display will be described with reference to FIG. 3. It should be understood that the following three-dimensional image display principle is merely an example of displaying a three-dimensional image.

As illustrated, in order to display a 3D real image in FIG. 3, a switching panel unit 155 is attached to an upper surface of the display unit 151. The switching panel 155 may display an image as a stereoscopic image by using binocular parallax. Binocular parallax means the difference between the right eye and the left eye's view of things. When the image (R) through the right eye and the image (L) through the left eye are synthesized in the human brain, the synthesized image may be seen as a stereoscopic image to the person. To this end, a single image is prepared by dividing the image of the right eye and the image of the left eye, and the left image (L) and the right image (R) are synthesized in units of pixels and displayed on one screen. Then, if the human eyes separate the pixel-by-pixel image by the left image and the pixel-by-pixel image by the right image, the image may be viewed as a stereoscopic image. The method of composing the two images may be mainly an interpolation method, but may vary depending on the method of forming the image. In FIG. 3, b denotes a barrier interval of the switching panel unit 155, g denotes a gap between the switching panel unit 155 and the display unit, and z denotes a distance from the position viewed by a person to the display unit. As shown in FIG. 3, when the two images are synthesized pixel by pixel (L, R), the time of the right eye corresponds to the pixel included in the right image, and the time of the left eye corresponds to the pixel included in the left image. The incident switching panel unit 155 may operate.

 When the switching panel unit 155 is to display a stereoscopic image (3D stereoscopic image), the switching panel unit 155 may be turned on to separate the incident time. In addition, the switching panel unit 155 may be turned off when the 2D image is to be displayed, and may be passed through without being separated from the incident time. Therefore, binocular disparity is not separated when the switching panel 155 is turned off.

Hereinafter, a method of displaying a 3D image in a mobile communication terminal according to the present invention will be described with reference to FIGS. 4 and 5.

That is, when the 3D virtual space image is displayed on the display unit 151 which is a touch screen, the switching panel unit 155 is turned on and displayed as a 3D stereoscopic image (S12). At this time, only at least a part of the virtual space image is displayed on the touch screen. In this state, the controller 180 monitors whether the tilt detection signal of the mobile communication terminal is generated from the tilt detection sensor 142 (S13). When the tilt detection signal is generated, the controller 180 changes the display of the displayed 3D virtual space image (S14).

As the switching panel unit 155 is turned on, the left eye image and the right eye image can be viewed through the left eye and the right eye of the user, respectively. The stereoscopic image is completed. That is, when the 3D virtual space image and the 3D icon are displayed on the display unit 151 which is a touch screen, the switching panel unit 155 is turned on to display the 3D image as a real 3D image. At this time, only at least a part of the virtual space image is displayed on the touch screen. On the other hand, the touch screen is a capacitive positive pressure composite touch screen that can receive both the electrostatic input and the positive pressure input. If only a power failure signal is generated for one of the displayed icons (S22), then the controller 180 monitors whether a positive pressure input signal is generated (S23). If the positive pressure input signal is also generated, the selected icon is executed or entered (S24). If no static pressure input signal is generated and only a power failure input signal is generated, the selected icon is highlighted (S25). The highlighting method may be determined by user setting. Meanwhile, a detailed description related to the second embodiment will be described later in detail with reference to FIGS. 7 and 8.

According to the second embodiment described above, the user can select, execute and highlight a three-dimensional icon, which is viewed in three dimensions, by the switching panel unit by using the electrostatic constant pressure composite touch screen.
