    Abstract: An imaging directional backlight apparatus including a waveguide, a light source array, for providing large area directed illumination from localized light sources. The waveguide may include a stepped structure, in which the steps may further include extraction features optically hidden to guided light, propagating in a first forward direction. Returning light propagating in a second backward direction may be refracted, diffracted, or reflected by the features to provide discrete illumination beams exiting from the top surface of the waveguide. The directional backlight may be arranged to switch between at least a first wide angular luminance profile mode and a second narrow angular luminance profile mode. The directional backlight is arranged to illuminate an LCD with a bias electrode arranged to switch liquid crystal directors in black state pixels between a first wide angular contrast profile mode and a second narrow angular contrast profile mode. Performance of privacy operation for off-axis snoopers is enhanced in comparison to displays with only directional backlights or switchable contrast properties.

    Abstract: Embodiments of the present disclosure provide a display driving method, an apparatus and a display system, and are used for displaying different video signals to different users simultaneously through one display device. The method comprises: receiving a first image signal and a second image signal which correspond to different users respectively; performing a signal process on the first image signal to acquire a processed first image signal, and performing a signal process on the second image signal to acquire a processed second image signal; driving pixels of odd-numbered columns in the pixel array to display the processed first image signal and driving pixels of even-numbered columns in the pixel array to display the processed second image signal, wherein a polarization direction of the emergent light of the pixels of odd-numbered columns is different from that of the emergent light of the pixels of even-numbered columns.

    Abstract: The present invention deals with a multi-person viewable 3-D display TV which comprises of a liquid crystal display (LCD) screen with backlights at multiple frequency ranges, a multidimensional control circuit to control information signals independently, a set of frequency filter visual glasses and audio apparatus integrated with the glasses. The LCD screen is made to display different pictures simultaneously on the full area of the screen, each at a particular frequency range different with others. This is fulfilled by proper pixel grid arrangement, effective controllability of pixels and correct sub-pixel addressing. A frequency channel is defined as the range of frequencies which contains the complete information of the video picture on the screen. The TV control circuit processes different audio and video (RF/IF) signals of different frequency channels independently, each in a similar methods as in a conventional LCD TV. The viewer's visual glass is configured to selectively enable the viewer to be able to view pictures of a particular frequency channel through the glass based on the signals from a processor. Thus, multiple pictures through different frequency channels are displayed simultaneously on the single LCD screen and are selectively viewed by different viewers depending on the glasses that they wear. Methods, devices, and systems to implement the above mentioned invention are hereby disclosed.

    Abstract: An image processing apparatus and method for processing an image using a multi-view image and pixel information are provided. The image processing method includes determining a view image that corresponds to a predetermined display direction of a display pixel of a display, determining at least one view image pixel corresponding to the display pixel in the determined view image based on a position of the display pixel in the display and pixel position information of the determined view image, and determining a pixel value of the display pixel based on a pixel value of the determined at least one view image pixel.

    Abstract: A multi view display is a display capable of simultaneously showing different images to viewers that see the display from different locations. Viewers do not see the images intended for other viewers at other locations. A multi view display forms images via a collection of multi-view pixels. A multi-view pixel is able to emit different light in different directions; in each direction, parameters of emitted light such as brightness, color, etc., can be controlled independently of the light emitted in other directions. Embodiments of the present invention comprise a computational pipeline and architecture for efficiently distributing image data to the multi-view pixels of a multi-view display.
