摘要： A waveguide display assembly includes a flat waveguide; a passage filter layer, which is divided into a plurality of area segments, which can be switched to light passage independently of each other; an image-generating unit, which is configured to generate different 2D images, each of which is intended only for one eye of a user for autostereoscopic 3D presentation, and to couple the 2D images into the waveguide in the form of collimated light beams, the propagation directions of which correspond to individual pixels; and a control unit, which is configured to control the image-generating unit and the passage filter layer such that only one or a subset of the area segments is switched to light passage at a time and, synchronously therewith, the image-generating unit generates only one image area segment of the 2D image intended for one eye of the user.

摘要： An image display device displays a stereoscopic image by using a parallax barrier method and includes a transmissive image display surface on which images of left-eye image data and right-eye image data are alternately displayed; an image forming unit including optical members having strip-shaped patterns with optical properties arranged on a surface located on a back surface side of the image display surface; and strip-shaped light sources arranged on an illumination arrangement surface, which is a surface located on a back surface side of the image forming unit, and configured to irradiate the image display surface with illumination light. A slit area of the parallax barrier method is formed by an image obtained by forming an image of the illumination light from the strip-shaped light sources on the back surface side of the image display surface by using the optical members of the image forming unit.

摘要： A three-dimensional (3D) image rendering method for a heads-up display (HUD) system including a 3D display apparatus and a catadioptric system is provided. The 3D image rendering method includes determining optical images corresponding to both eyes of a user by applying, to each of the positions of the eyes, an optical transformation that is based on an optical characteristic of the catadioptric system, and rendering an image to be displayed on a display panel included in the 3D display apparatus, based on a position relationship between the optical images and the display panel.

摘要： Some embodiments of an example apparatus may include a display, a first controllable diffuser overlaying the display, the first controllable diffuser being selectively operable to diffuse light in a first diffusion direction, and a second controllable diffuser overlaying the display, the second controllable diffuser being selectively operable to diffuse light in a second diffusion direction substantially perpendicular to the first diffusion direction. In some embodiments, an example method may include emitting a light beam from a light emitting device; linearly polarizing the light beam; passing the light beam through LC and birefringent materials; and applying a voltage to alter polarization of the LC material, from a first state causing the light to diffuse in a first direction upon passing through the birefringent material, to a second state causing the light beam to diffuse in a second direction upon passing through the birefringent material.

摘要： A system and method to dynamically control a configuration of parallax barriers includes performing skeletal tracking, using a skeletal tracking system, to determine a position of each viewer of content displayed by an image source. One of the parallax barriers among the parallax barriers is determined as being most closely associated with a viewing angle of each viewer, and the one of the parallax barriers is adjusted as needed to display the content as a three-dimensional image to one or more of the viewers with the viewing angle that is the most closely associated.

摘要： A gaming machine includes a processor, a video controller coupled to the processor, a display device coupled to the video controller, and an input device coupled to the processor and receiving an input from a player. The display device includes a rear display panel and a front display panel arranged between the player and the rear display panel, the front display panel including an electrochromic display panel that is spaced apart from the rear display panel in a viewing direction of the player. The video controller causes the display device to alternate between a first state for displaying a first image on the rear display panel and a second state for displaying a second image on the front display panel. In the first state, the video controller displays the first image on the rear display panel and causes the front display panel to be transparent, and in the second state, the video controller displays the second image on the rear display panel and causes the front display panel to be opaque.

摘要： A 3D display device and a method of driving the same are disclosed in the present disclosure. An electroluminescence display panel instead of a conventional backlight module is adopted to be arranged behind the liquid crystal display panel. In the 3D display mode, light emitting areas and black areas alternately arranged in both the row direction and the column direction are formed in the electroluminescent display panel, so that an abnormal grating structure is formed. In the 3D display mode, the first sub-pixels corresponding to the same light emitting area are controlled to display different gray level information so that the left and right eyes of a person located at two viewpoints receive an image of different gray level information. Therefore, stereoscopic vision is created and a naked-eye 3D display at the sub-pixel level is achieved.

摘要： Embodiments of the present disclosure disclose a three-dimensional display device and a driving method thereof. In a previous frame of display time, one part of second sub-pixels in a liquid crystal display panel are controlled to display a left eye view, and the other part of second sub-pixels display a right eye view. In a next frame of display time, positions of light emitting areas and black areas in an electroluminescent display panel are interchanged, and the second sub-pixels that display the left eye view in the previous frame display the right eye view in the next frame, and the second sub-pixels that display the right eye view in the previous frame display the left eye view in the next frame. The sum of the previous frame and the next frame of display time is less than a predetermined maximum time.
