  • Patent number: 11955038
    Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. The display may have a number of independently controllable viewing zones. Each viewing zone displays a respective two-dimensional image. Each eye of the viewer may receive a different one of the two-dimensional images, resulting in a perceived three-dimensional image. The electronic device may include display pipeline circuitry that generates and processes content to be displayed on the lenticular display. Content generating circuitry may generate content that includes a plurality of two-dimensional images, each two-dimensional image corresponding to a respective viewing zone. Pixel mapping circuitry may be used to map the two-dimensional images to the array of pixels in the lenticular display. The array of pixels may have a diagonal layout. An offset map may be used by the pixel mapping circuitry to account for the diagonal layout.

  • Publication number: 20240112628
    Abstract: An electronic device may include a lenticular display. The lenticular display may have a lenticular lens film formed over an array of pixels. A plurality of lenticular lenses may extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have a number of independently controllable viewing zones. The viewer may be particularly susceptible to artifacts caused by crosstalk at the edge viewing zones within the primary field of view of the display. Certain types of content may also be more vulnerable to crosstalk than other types of content. Therefore, to mitigate crosstalk artifacts, the pixel value for each pixel may be adjusted based on the viewing zone of the respective pixel and content information (such as texture information or brightness information) associated with the respective pixel.

  • Publication number: 20240088224
    Abstract: A semiconductor structure includes a first gate structure, a second gate structure coupled to the first gate structure, a source region, a first drain region, and a second drain region. The source region is surrounded by the first gate structure and the second gate structure. The first drain region is separated from the source region by the first gate structure. The second drain region is separated from the source region by the second gat structure. A shape of the first drain region and a shape of the second drain region are different from each other from a plan view.

  • Publication number: 20240031554
    Abstract: An electronic device may include a stereoscopic display with a plurality of lenticular lenses that extend across the length of the display. The lenticular lenses may be configured to enable stereoscopic viewing of the display such that a viewer perceives three-dimensional images. The display may have different viewing zones that account for horizontal parallax as a viewer moves horizontally relative to the display. The display may be dimmed globally based on the detected vertical position of the viewer. The magnitude of dimming applied to the display may increase with increasing deviation of the viewer from a baseline viewing angle. The display may render content that compensates for the real-time vertical position of the viewer. Another option for the stereoscopic display is to include a lens film that has an array of lenses. Each lens in the array of lenses spreads light in the horizontal direction and the vertical direction.

  • Patent number: 11838495
    Abstract: An electronic device may provide visual content at a virtual image distance that is farther from a user than the physical distance of the device from the user. A display in the device may have a transmissive spatial light modulator and beam steering device that are illuminated by a plane wave illumination system to provide computer-generated hologram images, may have a waveguide-based system that ensures that image content is presented at a desired virtual image distance, or may be a light-field display. The display may be used to display a left image in a left eye box and a right image in a right eye box. When viewed from the eye boxes, the left and right images fuse and are visible at a virtual image distance that is farther from the user than the distance physically separating the eye boxes from the display.

  • Patent number: 11747766
    Abstract: A method for rendering a light field comprises projecting rays from a viewpoint positioned at a first side of a spatial light modulator (SLM) to a clipping plane positioned at an opposing side of the SLM to form an elemental view frustum within a three-dimensional scene and rendering objects within the elemental view frustum to generate components of a first elemental image for the first elemental region. The SLM may include a tiled array of non-overlapping elemental regions and a top edge and a bottom edge of a first elemental region of the non-overlapping elemental regions are intersected by the rays to form the elemental view frustum. Furthermore, the light field may include the first elemental image and additional elemental images corresponding to the array of elemental regions and each one of the additional elemental images is rendered using an additional elemental view frustum.

  • Patent number: 10636336
    Abstract: A method, computer readable medium, and system are disclosed for generating mixed-primary data for display. The method includes the steps of receiving a source image that includes a plurality of pixels, dividing the source image into a plurality of blocks, analyzing the source image based on an image decomposition algorithm, encoding chroma information and modulation information to generate a video signal, and transmitting the video signal to a mixed-primary display. The chroma information and modulation information correspond with two or more mixed-primary color components and are generated by the image decomposition algorithm to minimize error between a reproduced image and the source image. The two or more mixed-primary colors selected for each block of the source image are not limited to any particular set of colors and each mixed-primary color component may be selected from any color capable of being reproduced by the mixed-primary display.

  • Publication number: 20200118252
    Abstract: Systems and methods for compensating for at least one optical aberration in a vision system of a viewer viewing a display. Image data for an image to be displayed is received, at least one parameter related to at least one optical aberration in the vision system of a viewer is received and an aberration compensated image to be displayed is computed based on the at least one received parameter related to the vision system of a viewer and on at least one characteristic of the light field element. The aberration compensated image is displayed on the display medium, such that when a viewer whose vision system has the at least one optical aberration views the aberration compensated image displayed on the display medium through a light field element, the aberration compensated image appears to the viewer with the at least one aberration reduced or eliminated.
