An autostereoscopic display comprises a pixelated display panel comprising an array of single color pixels or an array of sub-pixels of different colors and a view forming arrangement comprising an array of lens elements. The pixels form a square (or near square) grid, and the lenses also repeat in a square (or near square) grid. A vector p is defined which relates to a mapping between the pixel grid and the lens grid. Regions in the two dimension space for this vector p are identified which give good or poor banding performance, and the better banding performance regions are selected.

A first input unit in a head-up display obtains a distance to an object. A second input unit obtains a user's eye position. An optical system projects, into the user's field of view, a virtual image of an image displayed on a display panel. A processor causes the display panel to display a parallax image. An optical element causes a first image displayed on the display panel to reach the user's first eye and a second image on the display panel to reach the user's second eye. The processor causes the display panel to display an image element in the parallax image as at least partially superimposed on the object. The processor performs first control to fix, in response to the distance to the object greater than or equal to a predetermined first distance, parallax of the image element to a value other than 0 corresponding to the first distance.

A stereoscopic display, including a display panel and a lenticular plate is provided. The display panel has multiple pixels arranged in an array. The lenticular plate has multiple lenticulars. Each of the lenticulars extends along an extending direction, and the lenticulars are arranged along a periodical direction. The pixels are divided into multiple group. The lenticular plate transmits lights emitted by the pixels of different groups towards multiple different viewing zones, so as to form a stereoscopic vision. In the periodical direction, a pitch of the pixels of the same group is greater than a pitch of the lenticulars.

A three-dimensional display device includes a display panel, a barrier panel, and a controller that controls the display panel and the barrier panel. The controller defines multiple first image areas and multiple second image areas in the display panel, causes the first image areas to be at first intervals in a first direction, causes displaying of a first image viewable by a first eye of a user in the first image areas and a second image viewable by a second eye of the user in the second image areas, defines, in the barrier panel, multiple first transmissive areas transmissive to the image light at a first transmissivity and multiple second transmissive areas transmissive to the image light at a second transmissivity, causes the first transmissive areas to be at second intervals in the first direction, and performs an irregular process at third intervals in the first direction.

A light field display device including: a display panel including a plurality of subpixels each emitting a light field; and a lenticular lens array on the display panel and including a plurality of lenticular lenses, wherein the plurality of lenticular lenses correspond to a plurality of subpixel groups each including the plurality of subpixels, and wherein a width of each of the plurality of subpixel groups is greater than a width of each of the plurality of lenticular lenses.

A method for implementing 3D image display and a 3D display device are provided. The method comprises: detecting a posture change of a 3D display device, which comprises a multi-viewpoint 3D display screen comprising multiple composite pixels and a lenticular grating covering the multiple composite pixels, each composite pixel comprises multiple composite subpixels, each composite subpixel comprises multiple subpixels, and the lenticular grating is obliquely arranged to cover multiple subpixels along a first direction of the 3D display device to define multiple first posture viewpoints and cover at least two composite pixels along a second direction of the 3D display device to define at least two second posture viewpoints; and when a posture of the 3D display device changes, adjusting a display orientation of a 3D image, so that the 3D image is kept in an initial display orientation before a posture change of the 3D display device.

A three-dimensional display device includes a display panel, an optical panel, and a controller. The display panel displays a parallax image. The optical panel defines a traveling direction of image light. The controller controls the parallax image based on positions of a first eye and a second eye of a user. The controller causes a predetermined proportion of pixels to display a black image. The predetermined proportion is determined to cause, for the first and second eyes of the user at a predetermined reference position, a black image to be displayed by a pixel at one end or two ends of multiple first areas viewable to the first eye and not viewable to the second eye and by a pixel at one end or two ends of multiple second areas viewable to the second eye and not viewable to the first eye in a parallax direction.

A stereoscopic display, including a display panel and a lenticular plate is provided. The display panel has multiple pixels arranged in an array. The lenticular plate has multiple lenticulars. Each of the lenticulars extends along an extending direction, and the lenticulars are arranged along a periodical direction. The pixels are divided into multiple group. The lenticular plate transmits lights emitted by the pixels of different groups towards multiple different viewing zones, so as to form a stereoscopic vision. In the periodical direction, a pitch of the pixels of the same group is greater than a pitch of the lenticulars.
