A method and device for increasing a resolution for each viewpoint in a glassless three-dimensional (3D) display. A method of controlling a three-dimensional (3D) display device including a display panel and a lens includes performing time-division on a plurality of viewpoint images such that each of the viewpoint images is divided into n division images, transferring the division images to the display panel by increasing n times a frame rate of the division images, and controlling the lens such that the division images transferred to the display panel pass through a lens cell.

In some embodiments, optical systems with a reflector and a lens proximate a light output opening of the reflector provide light output with high spatial uniformity and high efficiency. The reflectors are shaped to provide substantially angularly uniform light output and the lens is configured to transform this angularly uniform light output into spatially uniform light output. The light output may be directed into a light modulator, which modulates the light to project an image.

In one example, a device for retrieving video data includes a display interface coupled to a display, a memory configured to store video data, and one or more processors configured to determine a plurality of regions of video data to be displayed via the display, retrieve video data having a first quality for a first subset of the plurality of regions at which a visual focus of a user is directed, retrieve video data having a second quality for a second subset of the plurality of regions that neighbor the first subset of the plurality of regions, wherein the second quality is lower than the first quality, and retrieve video data having a third quality for a third subset of the plurality of regions that is outside the first subset and the second subset, wherein the third quality is lower than the second quality.

The display device includes a display panel on which sub-pixel pairs are arranged in a lateral direction, and a parallax barrier shutter panel on which sub-openings that can be changed between a light transmittance state and a light-shielding state are arranged in a lateral direction. Arbitrary allocated number of adjacent sub-openings among the plural sub-openings belonging to a reference parallax barrier pitch are put into a light transmittance state, and the remaining sub-openings are put into a light-shielding state, so that a general opening is formed on the parallax barrier shutter panel. A sub-opening pitch of the sub-opening on the boundary part between the adjacent common driving areas is different from the sub-opening pitch of the other sub-openings.

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.

A three-dimensional (3D) display system is provided. The 3D display system includes a backlight plate, a display panel, a light-splitting device, and a polarization state controller. The display panel is configured to display a two-dimensional (2D) image in a 2D mode or to display a 3D image in a 3D mode. The light-splitting device is configured to an arrangement module configured to pass the 2D image in the 2D mode, and to separate the 3D image into a left image and a right image. Further, the polarization state controller is disposed between the display panel and the light-splitting device and is configured to rotate a polarization direction of light emitted from the display panel in the 2D mode, and to keep the polarization direction of the light emitted from the display panel in the 3D mode.

A display device includes: a plurality of gate lines; and a gate driver including a plurality of stages which transmits a gate voltage to the gate lines, where first to fourth clock signals and first to fourth inverted clock signals having phases opposite to phases of the first to fourth clock signals, respectively, are sequentially input to each repetition unit of the stages, where each repetition unit is defined by eight consecutive stages, a carry signal output by a j-th stage is transmitted to a (j+4)th stage, and a carry signal output by the (j+4)th stage is transmitted to the j-th stage, where j is a natural number.

A 3D display device having a lens-switching function. The device includes an LCD picture layer, a lens-array plate, an LCD shielding pattern layer, and a synchronous picture providing system. The synchronous picture providing system is connected with the LCD picture layer and the LCD shielding pattern layer such that the LCD picture layer and the LCD shielding pattern layer are synchronous to respectively display a 3D picture and a shielded pattern. Through increasing an area of black shielding pattern, an edge of each lens unit corresponding to the shielding region is shielded, the area of a single light transparent region is reduced, and a light transparent aperture of a lens unit corresponding to the shielding region is reduced in order to eliminate a cross talk generated by scattering and bluntness at the edge.

An autostereoscopic display uses a beam control system and a pixelated spatial light modulator. Different display modes are provided for the displayed image as a whole or for image portions. These different modes provide different relationships between angular view resolution, spatial resolution and temporal resolution. The different modes make use of different amounts of beam spread produced by the beam control system.
