Display driving method, apparatus and display system
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.
Computational pipeline and architecture for multi-view displays
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.
DYNAMIC IMAGE ADJUSTMENT TO ENHANCE OFF- AXIS VIEWING IN A DISPLAY ASSEMBLY
A display assembly includes a display console displaying at least one image on an image plane. The image is divided into a plurality of pixels. A controller is operatively connected to the display console and includes a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for dynamically adjusting the image in real-time for off-axis viewing. The controller is programmed to generate a compensation-over-viewing-angle map which includes respective compensation factors for each of the plurality of pixels for multiple viewing positions. In one embodiment, the controller is programmed to apply separate respective compensation factors for the instantaneous viewing positions of a first user at a time j and a second user at a time k. In another embodiment, the controller is programmed to apply first and second compensation factors simultaneously at a time m, for a first image and a second image, respectively.
Directional projection display
In some examples, a projection display surface is configured to reflect a first image or image portion in a first direction and a second image or image portion in a second direction. In some cases, first light corresponding to the first image is projected onto a display surface that includes a first plurality of reflectors configured to reflect the first light in a first direction, but not reflect second light corresponding to the second image. The display surface may further include a second plurality of reflectors to reflect the second light in a second direction, but not reflect the first light. In some examples, the first light is within a first wavelength range and the second light is within a second, different wavelength range. In other examples, the first light has a first polarization and the second light has a second, different polarization.
VIDEO DISPLAY FOR VIEWING THROUGH POLARIZED ACTIVE SHUTTER GLASSES
A method for receiving an input video frame is provided that generates two obscured frames from the input frame by copying odd lines interspersed with noise lines to one frame and copying even lines interspersed with noise lines to the other frame. The obscured frames are then displayed on a screen with lines polarized in different directions, and a timing signal is output to polarized active shutter glasses such that one lens allows polarized light for lines copied from the original input frame to pass through the lens and be visible to a wearer while the other lens blocks the added noise lines from the wearer's view.
Image display method and apparatus
An image display apparatus according to an embodiment of the present invention comprises: an IR emitter controller for recognizing a pair of 3D glasses connected to the image display apparatus; a video multiplexer for receiving a plurality of displayed video data using a plurality of pairs of 3D glasses, setting a frame rate for the plurality of video data to assign a frame period thereto, and multiplexing the plurality video data according to the frame period assigned at the set frame rate, when the plurality of pairs of 3D glasses is connected to the image data apparatus; and a display unit for frame-sequentially displaying the multiplexed video data.
Privacy display apparatus
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.
Methods of displaying an electronic program guide
A method of displaying an electronic programming guide, comprising: outputting a video signal from a receiver to a display device, the video signal including program service content for display on the display device; receiving a signal at the receiver, the signal including a command to display an electronic programming guide; in response to receiving the signal, determining if there is at least one viewer of the display device that does not want to view the electronic programming guide; and in response to determining that there is at least one viewer that does not want to view the electronic programming guide, projecting the electronic programming guide from the receiver to a projection surface.
METHOD AND DEVICE FOR OPERATING A LENTICULAR DISPLAY
In one implementation, a method of operating a lenticular display is performed by a device including a processor, non-transitory memory, an image sensor, and a lenticular display. The method includes displaying, via the lenticular display, first content at a horizontal angle of a first user and second content, different than the first content, at a horizontal angle of a second user. The method further includes displaying, via the lenticular display, the first content at a second horizontal angle of the first user and the second content at a second horizontal angle of the second user.
Mode-switchable backlight, privacy display, and method
A mode-switchable backlight and mode-switchable privacy display provide narrow-angle emitted light during a first mode and broad-angle emitted light in a second mode, the broad-angle emitted light being a combination of the narrow-angle emitted light and bidirectional emitted light. The mode-switchable backlight includes a first directional backlight and a second directional backlight. The first directional backlight is configured to provide the narrow-angle emitted light during both of the first mode and second mode, while the second directional backlight is configured to provide the bidirectional emitted light exclusively during the second mode. The mode-switchable privacy display includes an array of light valves configured to modulate the narrow-angle emitted light as a private displayed image during the first or privacy mode and to modulate broad-angle emitted light as a public displayed image during the second or public mode.
