A head-up display device includes: a display unit that produces a display light for the left eye by modulating a first illumination light derived from superimposing first illumination light beams output from a first region of a fly eye lens and produces a display light for the right eye by modulating a second illumination light derived from superimposing second illumination light beams output a second region of the fly eye lens; and an image processing unit that produces an image for the left eye and produces an image for the right eye; and a display control unit that causes a display unit to display the image for the left eye when the first illumination light is produced and causes the display unit to display the image for the right eye when the second illumination light is produced.

This disclosure describes methods, techniques, devices, and apparatuses for graphics and display processing for light field projection displays. In some examples, this disclosure describes a projection display system capable of rendering and displaying multiple annotations at the same time. An annotation is any information (e.g., texts, signs, directions, logos, phone numbers, etc.) that may be displayed. In one example, this disclosure proposes techniques for rendering and displaying multiple annotations at the same time at multiple different focal lengths.

A system and method can include receiving a set of views, encoding the set of views, and displaying the set of views such that they are perceived as a holographic image.

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.

An illumination unit of an embodiment of the present technology includes: an illumination optical system configured to generate illumination light; and a plurality of lenses configured to reduce a divergence angle of the illumination light. The illumination optical system includes: a light source (20) configured to apply light onto an end surface of one of a first substrate and a second substrate; and a light modulation layer (30) provided in a gap between the first substrate and the second substrate. The illumination optical system includes an electrode configured to generate an electric filed that generates, in the light modulation layer (30), a plurality of linear scattering regions (30B) in a three-dimensional mode, and to generate an electric field that generates, in the light modulation layer, a planar scattering region in a two-dimensional display mode. The lenses are arranged side by side in a direction in which the linear scattering regions extend, and are also arranged side by side in a direction intersecting with the direction in which the linear scattering regions extend.

An image display device includes a display including a plurality of light emitting elements that are two-dimensionally arranged, the plurality of light emitting elements being divided into a plurality of division regions, each of which includes more than one of the plurality of light emitting elements; and a lens that is located near a surface of the display so as to correspond to the division regions and that forms a display image by focusing each of images displayed in the respective division regions as a real image or a virtual image so that the focused images overlap on a same image plane.

A method and a device for producing multi-view images optical films used therein are disclosed. The method and device use an optical film 2, comprising a superlens array 3 with between 0.5 to 225 superlenses per inch, formed by two arrays of positive microlenses which are fixed relative to one another. In order to produce a multi-view image 1 between a viewer 11 and the optical film 2, an array 10 of elemental images is arranged between the focal plane 9 of the superlenses 3 and the optical film 2.

A three-dimensional image display apparatus is provided. The three-dimensional image display apparatus includes an element image array, a backlight source, and a fly-eye lens array. The element image array is disposed between the backlight source and the fly-eye lens array. Incident angles of lights emitted from different directional light sources with respect to the element image array are different. The image resolution of the three-dimensional image display apparatus is raised by using the backlight source having the multiple directional light sources.

Provided is a display device. The display device includes a display panel and a microlens array disposed on a light-emitting side of the display panel, wherein the display panel includes a plurality of pixel islands in which a first pixel island displaying a first color, a second pixel island displaying a second color, and a third pixel island displaying a third color adjacent to one another form a repeating unit. In a same repeating unit, three sub-pixels at the same positions relative to their respective microlens units in the first pixel island, the second pixel island, and the third pixel island are disposed at three vertexes of a triangle respectively, and thus form a color fusion pixel. In addition, the display device further includes microlens arrays in one-to-one correspondence with the plurality of pixel islands to realize 3D display.
