The disclosure describes various aspects of an architecture for light emitting elements in a light field display. In an aspect, a light field display can include multiple picture elements (e.g., super-raxels), where each picture element includes multiple sub-picture elements monolithically integrated on a same semiconductor substrate. Each sub-picture element has a respective light steering optical element and includes an array of light emitting elements (e.g., sub-raxels) that produce the same color of light. The light steering optical element can include at least one microlens, at least one grating, or a combination of both. Separate groups of light emitting elements can be configured and a directional resolution of the light field display can be based on the number of groups. The light field display also includes electronic means configured to drive the light emitting elements in each sub-picture element.

Apparatuses and methods for displaying a 3-D representation of an object are described. Apparatuses can include a rotatable structure, motor, and multiple light field sub-displays disposed on the rotatable structure. The apparatuses can store a light field image to be displayed, the light field image providing multiple different views of the object at different viewing directions. A processor can drive the motor to rotate the rotatable structure and map the light field image to each of the light field sub-displays based in part on the rotation angle, and illuminate the light field sub-displays based in part on the mapped light field image. The apparatuses can include a display panel configured to be viewed from a fiducial viewing direction, where the display panel is curved out of a plane that is perpendicular to the fiducial viewing direction, and a plurality of light field sub-displays disposed on the display panel.

A spatial light modulator is constituted by a plurality of pixels. A rearrangement optical element guides the light generated by the plurality of pixels of the spatial light modulator onto the screen to rearrange a plurality of pixels on a screen. Each lens of a lens array emits the light generated by the plurality of pixels rearranged on the screen as light beams in respective different directions. A control device controls the spatial light modulator such that a three-dimensional image is presented by the plurality of light beams emitted by a plurality of lenses of the lens array.

In one embodiment, it is proposed an auto-stereoscopic display device comprising a display panel configured to deliver n different images views, with n a integer greater or equal to two; and an optical filter which is configured to control diffusion directions of said n different images views. The auto-stereoscopic display device is remarkable in that it comprises opaque materials (201, 202) positioned in said display panel in such way that a content indicating a direction that a user should follow in order to be in a correct sweet spot, is delivered on an edge of different views, when said display panel is on.

Disclosed is a three dimensional (3D) continuous display system based on a plurality of projexels. Each projexel may include of a plurality of light emitting devices. Each light emitting device may project a directional beam of light that spans an angular range. The sum of the angular ranges of each beam of light total an angular range for the projexel. Each projexel is also associated with a set of transition angles. The transition angles may be defined by the angle where two beams coincide. The projexels are configured such that sets of transition angles between adjacent projexels are offset.

A liquid crystal lens (1110) which controls an optical path and a display (30)which includes the liquid crystal lens. The liquid crystal lens (1110) includes a first electrode (110) and a second electrode (120) facing each other, a liquid crystal layer (130) interposed between the first electrode (110) and the second electrode (120) and having flat top and bottom surfaces (130_1, 130_2), and a dielectric layer (141) interposed between the second electrode (120) and the liquid crystal layer (130). The dielectric layer (141) includes a section (L1, L2) in which capacitance between top and bottom surfaces (141_1, 141_2) of the dielectric layer (141) changes along a horizontal direction in the plane of the dielectric layer (141).

An autostereoscopic display 101, which provides a depth perception by providing a viewer's left and right eyes (104a, 104b) with two slightly different perspectives of an image to be displayed, is provided for ultrasound guided interventions with a surgical instrument (103). The surgeon watches displayed ultrasound data (102), rendered for at least two views. The plane at which those views (L, R) intersect is adjusted to correspond exactly with the tracked three-dimensional position within a displayed scene of the surgical instrument (103), which position can be extracted from the three-dimensional ultrasound data by means of, for example, 3D object recognition. Thus, the point of reconstruction of the image presented to the viewer can be dynamically adjusted to correspond with the position of the surgical instrument on which the surgeon's eyes are presumed to be focused.
摘要:
The invention relates to autostereoscopic multi-user displays with a sequential representation consisting of a sweet-spot unit and an image matrix. The sweet-spot unit, configured from an illumination and focussing matrix and positioned in front of the image matrix, focuses approximately parallel light bundles in sweet spots onto the eyes of observers. The aim of the invention is to achieve, by optical means, a tracking with a clear image allocation for observers located at a lateral distance from one another that is less than the distance between the eyes. The freedom of movement in terms of the display should be maintained and the information that is assigned to each observer should remain private with regard to other users. To achieve this, the sweet spots are limited horizontally and vertically with the aid of a focussing matrix, which consists of two crossed lens arrays L1 and L2, or a two-dimensional lens array comprising lenses that are arranged in a matrix, or a double lens array. Said focussing matrix forms a sweet-spot matrix comprising two-dimensionally limited sweet-spot pairs, which contain all controllable observer positions. Autostereoscopic displays of this type can be used in a 2D and/or 3D mode.
