A system configured to display autostereoscopic video (AV) may determine a depth setting for displaying the AV based on at least one of user parameters or device parameters, and may proceed to display the AV on a display based on the depth setting. In one embodiment the system may try to obtain user parameters before relying on device parameters. User parameters may be available from user profiles. For example, facial recognition may be used to determine if a user profile exists for a user. If a user profile is determined not to exist for the user, then the system may sense a distance from the display to the viewer, and may proceed to determine the depth setting based on the distance and device characteristics. Device characteristics may identify the manufacturer/model of the system, the type/size of display on which the AV will be viewed, the abilities of the system, etc.

A display system comprises a projector combined with a retro reflective screen and a viewer distance from the projector such that the observation angle is less than approximately 2-3 degrees. The brightness of the image on the screen for the proposed display system is increased by a factor of ˜100-500× as compared to traditional display systems with for an equivalent power/intensity light source.

The liquid crystal grating of the present disclosure may include a plurality of grating element groups for forming dark fringes and transparent fringes. The dark fringe of each grating element group may be arranged adjacent to a transparent fringe of a neighboring grating element group. Each grating element group may include a plurality of first grating elements and at least one second grating element arranged parallel to each other. At least one of the first grating elements is transparent so as to form the transparent fringe of the grating element group, and different first grating elements are enabled to be transparent so as to change positions of the transparent fringes.

A three-dimensional display device for displaying a three-dimensional image, including: a gaze point obtaining unit which obtains a position of a gaze point of a viewer; a fusional area determination unit which determines a fusional area where binocular fusion is allowed, based on the obtained position of the gaze point; a correction unit which corrects the three-dimensional image so as to suppress display of an object that is included in the three-dimensional image outside the fusional area; and a display unit which displays the corrected three-dimensional image.

An optical film and an autostereoscopic 3D display using the same are provided. The optical film includes a concave lens layer and a birefringence layer. The concave lens layer has plurality of concaves and a presumed refractive index. The birefringence layer overlaps the concave lens layer and includes a plurality of liquid crystal units filled and cured in the concaves. The birefringence layer has a short axis refractive index. The presumed refractive index is between 100.1%-102.8% of the short axis refractive index. The autostereoscopic 3D display includes the optical film, a liquid crystal switch module, and a display panel module. The liquid crystal switch module is disposed on one side of the optical film. The display panel module is disposed on one side of the liquid crystal switch module opposite to the optical film and has a display surface facing the liquid crystal switch module. Image light generated by the display panel module can pass through the optical film after its polarization direction is modulated by the liquid crystal switch module.

A 3D holographic virtual object display controlling method and apparatus based on human-eye tracking are provided. The display controlling method comprises the following steps of: activating tracking of human eyes of a user; tracking motions of eyeballs of the user; controlling a 3D holographic virtual object presented in a display interface to rotate in response to the motions of the eyeballs of the user; and ending up the tracking of the human eyes of the user. Thereby, the present disclosure can control rotation of a 3D holographic virtual object presented in a display interface by tracking eyeballs and in response to the motions of the eyeballs, which makes the operations convenient and easy.

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.

Disclosed is a stereopsis display device that includes, for example, a plurality of sub-pixels including openings; a black matrix defining the openings; and a plurality of lenticular lenses slanted at a slant angle, wherein one view matrix includes a unit of M number of sub-pixels arranged in a first direction and N number of sub-pixels arranged in a second direction, wherein M and N are a positive integer, that is divided into sub-pixels opened by the openings and sub-pixels covered by the black matrix, and wherein a number of the sub-pixels of the unit opened by the openings within a viewing zone formed by the lenticular lenses is N.

A method and apparatus for rendering content are provided. The content rendering method includes determining at least one reference plane set to three dimensional (3D) content, in response to a request for displaying 3D content; classifying objects, displayed on the 3D content, based on a location of each object relative to a location of the reference plane into objects corresponding to at least one of a first left image or a first right image, and objects corresponding to at least one common image, respectively; creating the first left image, the first right image and the at least one common image, according to the respective classified objects; and combining the at least one common image with each of the first left image and the first right image to form a second left image and a second right image, respectively.

Left and right visual feeds are configured to form contiguous non-stereo left, stereo central, and non-stereo right display regions. Viewed together, an appearance of full-width stereo three-dimensionality may be achieved. The left and right display regions have the brightness of the left or right feeds respectively, while the central display region has the combined brightness of the left and right feeds. The parts of the left and right feeds that cooperate to form the stereo central display region may be scaled in brightness, so that the central display area is of uniform brightness with the left and right display areas, or smoothly varying, continuous, varying in a controlled manner, etc., rather than appearing as a sharply-defined area twice as bright as the left and right display areas. Scaling profiles may be uniform step-downs, linearly decreasing, quadratically decreasing, otherwise curved, some combination thereof, etc.
