    BACKGROUND OF THE INVENTION



    [0002] Main principle of 3D display technology is that a left eye and a right eye of a viewer receive different images respectively, and the viewer can perceive the levels of the images by analyzing and overlapping the image for left eye and the image for right eye in the viewer's brain so as to produce a stereoscopic sense.

    [0003] At present, the 3D display devices are mainly classified into two types, one type of the 3D display devices is one required to be viewed by wearing 3D glasses, and the other type of the 3D display devices is autostereoscopic 3D display. Parallax barrier technology is a kind of autostereoscopic 3D technology, which, by means of a parallax barrier member, enables the image for left eye to be seen only by the left eye and cannot be seen by the right eye, at the same time, the image for right eye to be seen only by the right eye and cannot be seen by the left eye, so that a picture for left eye and a picture for right eye are formed respectively, and a 3D picture is formed finally. Therefore, it is required to add an extra parallax barrier member for an existing 3D display to realize 3D display. However, there is limitation to the existing display device realizing 3D display by means of the parallax barrier member, for example, since the parallax barrier member is fixed on the display panel, the display device can only display 3D image, and since sizes and positions of the light-shielding regions of the parallax barrier member are fixed, it is impossible for the parallax barrier member to be adapted to distances between two eyes of various viewers and to self-adaptively adjusts distance from a viewer to the display to obtain optimum 3D display effect.

    [0004] US 2013/053100 A1 discloses a mobile terminal including a display unit to display a left-eye image and a right-eye image, a barrier panel to generate a parallax barrier region, and a barrier controller to adjust the parallax barrier region. Furthermore, a method for controlling a barrier pattern is disclosed which includes calculating a relative position of a barrier panel with respect to a display unit, adjusting a barrier region generated in the barrier panel according to the calculated relative position, and displaying a left-eye image and a right-eye image via the display unit.

    [0005] US 2009/207124 A1 discloses a display device including a driver, a main display panel that receives an image signal from the driver to display an image and that is substantially fixed to the driver, a backlight assembly that is disposed between the main display panel and the driver to radiate light to a rear surface of the main display panel, and a sub-display panel that receives a image signal from the driver to display an image and that can be moved. The display device includes a first mode, in which the sub-display panel is disposed to be opposite to a rear surface of the main display panel, and a second mode, in which the sub-display panel is disposed to be opposite to a front surface of the main display panel.
