1. A three-dimensional display device, comprising:

  • a display module defining a plurality of pixels in a pixel matrix, wherein the pixels comprise a first set of pixels and a second set of pixels;

    a barrier module disposed at a viewer side of the display module, wherein for a viewer at the viewer side, the barrier module is configured to allow light emitted from the first set of pixels to be viewable only by a left eye of the viewer, and allow light emitted from the second set of pixels to be viewable only by a right eye of the viewer, such that the viewer perceives the light emitted from the first set of pixels as a left-eye view and the light emitted from the second set of pixels as a right-eye view, and perceives the left-eye view and the right view to form a three-dimensional virtual image between the viewer and the display module;

    a sensing module configured to receive a plurality of first scan signals, to detect an object at the viewer side of the three-dimensional display device in response to receiving the first scan signals, and to generate sensing signals in response to detecting the object; and

    a controller electrically connected to the display module and the sensing module, the controller comprising a processor and a non-volatile memory storing computer executable codes, wherein the codes, when executed at the processor, are configured togenerate display signals, and send the display signals to the display module to control the pixels;

    receive the sensing signals from the sensing module, and generate an object coordinate according to the sensing signals;

    in response to a display instruction,generate the display signals for an out-of-screen three-dimensional virtual input device, wherein the display signals are configured to control the first set of pixels to display the left-eye view of the three-dimensional virtual input device, and to control the second set of pixels to display the right-eye view of the three-dimensional virtual input device; and

    generate a sensing instruction to indicate that the three-dimensional virtual input device is displayed;

    in response to the sensing instruction, generate the first scan signals for the sensing module, and send the first scan signals to the sensing module; and

    in response to the object coordinate matching coordinates of an input region of the three-dimensional virtual input device, generate an input command;

    wherein the codes comprise;

    a pixel control module configured to generate the display signals in response to a plurality of image signals, and send the display signals respectively to the display module to control the pixels;

    an image processing module configured to generate the image signals from an image; and

    a sensing control module configured to generate the first scan signals for the sensing module and send the first scan signals to the sensing module in response to the sensing instruction, receive the sensing signals from the sensing module, and generate the object coordinate by comparing to the sensing signals;

    wherein when the image corresponds to the three-dimensional virtual input device, the pixel control module generates the display signals to control the first set of pixels to display the left-eye view of the three-dimensional virtual input device, and to control the second set of pixels to display the right-eye view of the three-dimensional virtual input device, and generates the sensing instruction for the sensing control module to indicate that the three-dimensional virtual input device is displayed.
