A display may include an array of pixels covered by lenticular lenses. The lenticular lenses may cause expansion of light primarily in a horizontal direction. To improve the perceived resolution of the display, the horizontal resolution of the pixels on the display may be increased. In one possible layout, each pixel includes one red sub-pixel, one blue sub-pixel, and one green sub-pixel. The sub-pixels may be non-square rectangular. The sub-pixels may be the same size or may have the same widths and different heights. Each pixel may be asymmetric about a horizontal axis. In a given row, the pixels may alternate between first and second layouts. The second layout may be a vertically flipped version of the first layout.

Pixel arrangements for displays with lenticular lenses

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. Crosstalk between viewing zones and disparity between images received from different viewing zones may result in disparity-caused shifts in images perceived by viewer of the lenticular display. To mitigate these disparity-caused shifts, compensation circuitry may be included in the display pipeline circuitry. The compensation circuitry may include stored disparity-caused shift calibration information that is used for the compensation. The stored disparity-caused shift calibration information may be a polynomial function that outputs a magnitude of disparity-caused shift for a given pixel location.

Displays with disparity-caused shift compensation

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.

Pixel mapping in a display pipeline

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.

Electronic devices with vision correcting displays

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.

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.

A method, computer readable medium, and system are disclosed for adjusting an angular sampling rate during rendering. The method includes the steps of determining a location of a gaze within a displayed scene, and adjusting, during a rendering of the scene, an angular sampling rate used to render at least a portion of the scene, based on the location of the gaze within the displayed scene.
