Abstract: In some examples, an apparatus may include a backlight unit (BLU) including an electronic integrated circuit layer, a photonic integrated circuit layer, a color conversion module, and a display interface layer. In some examples, a BLU may include at least one laser or may be configured to receive laser light from at least one external laser source. Laser light may be transmitted towards a portion of the display interface layer using the photonic integrated circuit. Color conversion modules may be used to convert the laser light into one or more desired colors. Example apparatus may be used in head-mounted devices such as augmented reality and/or virtual reality devices. Other devices, methods, systems, and computer-readable media are also disclosed.

Abstract: In one embodiment, a computing system may determine, determine an estimated distance of an eye of a user to a display plane of a display. The system may access correction maps corresponding to a number of reference distances to the display plane of the display. The system may select a first reference distance and a second reference distance based on the estimated distance. The system may generate a custom correction map for the user based on an interpolation of a first correction map corresponding to the first reference distance and a second correction map corresponding to the second reference distance. The system may adjust an image to be displayed on the display using the custom correction map. The custom correction map may correct non-uniformity of the display as viewed from the eye of the user. The system may display the image adjusted using the custom correction map on the display.

Abstract: In one embodiment, a computing system may determine a target grayscale value associated with a target image to be represented by a plurality of subframes. The system may determine grayscale ranges based on the target grayscale value. Each grayscale range may correspond to a combination of zero or more subframes of the plurality of subframes. The system may select dot subsets from a dithering mask based on the grayscale ranges. Each of the dot subsets may correspond to a grayscale range. The system may generate the subframes based on (1) the selected dot subsets and (2) respective combinations of zero or more subframes. The subframes may have a smaller number of bits per color than the target frame. The system may display the subframes sequentially in time domain on a display to represent the target image.

Abstract: A display assembly generates environmentally matched virtual content for an electronic display. The display assembly includes a display controller and a display. The display controller is configured to estimate environmental matching information for a target area within a local area based in part on light information received from a light sensor. The target area is a region for placement of a virtual object. The light information describes light values. The display controller generates display instructions for the target area based in part on a human vision model, the estimated environmental matching information, and rendering information associated with the virtual object. The display is configured to present the virtual object as part of artificial reality content in accordance with the display instructions. The color and brightness of the virtual object is environmentally matched to the portion of the local area surrounding the target area.

Abstract: A display system may include a light source that emits input light having a wavelength within a source wavelength range and an array of color conversion units overlapping a display area. A first set of color conversion units of the array of color conversion units may include a first color conversion medium that converts the input light to a first color of light having a wavelength within a first wavelength range that is different than the source wavelength range. The display system may also include a waveguide having an out-coupler that directs the input light from the light source toward the array of color conversion units. Various other devices, systems, and methods are also disclosed.

Abstract: In one embodiment, the system may determine an estimated distance of an eye of a user to a display plane of a display. The system may access, from a memory storage, a number of transmission maps characterizing non-uniform transmission characters of the display as measured from a number of pre-determined view positions within a measurement plane. The measurement plane may be separated from the display plane by a known distance. The system may generate a custom transmission map for the estimated distance of the eye based on the transmission maps using light field rendering. The system may determine a custom correction map based on the custom transmission map. The system may adjust an image to be displayed on the display using the custom correction map. The system may display the image adjusted using the custom correction map on the display.

Abstract: In one embodiment, a computing system may determine, a predicted eye position of a viewer corresponding to a future time moment for displaying a frame. The system may generate a first correction map for the frame based on the predicted eye position of the viewer. The system may retrieve one or more second correction maps used for correcting one or more proceeding frames. The system may generate a third correction map based on the first correction map generated based on the predicted eye position of the viewer and the one or more second correction maps used for correcting the one or more proceeding frames. The system may adjust pixel values of the frame based at least on the third correction map. The system may output the frame with the adjusted pixel values to a display.

Abstract: In one embodiment, a computing system may determine a group of subpixels, that are associated with different color channels, within a display region of a display. The system may determine a micro-pixel corresponding to a basic unit shape configured to evenly divide the display region and each subpixel. The system may represent the display region as a group of micro-pixels and each subpixel as a combination of one or more micro-pixels in the group of micro-pixels. The system may determine a constraint for each color channel of the display region based on the group of micro-pixels. The constraint may constrain the micro-pixels associated with a same subpixel to have a same color value. The system may generate, based on an optimization process using the constraint, a filter for the display region. The filter may be configured to adjust image pixel values to be displayed by the group of subpixels.

Abstract: In one embodiment, a computing system may render an image to be output by a display which sequentially outputs pixel rows of the image at a row-to-row velocity. The system may predict, based on eye-tracking data, an eye-motion velocity within a timeframe for displaying the image. The system may determine a predicted retina projection displacement for each pixel row based on the row-to-row velocity and eye-motion velocity. The system may determine a first correction displacement for each pixel row based on the predicted retina projection displacement. The system may determine a cumulative correction displacement based on the first correction displacement. The system may determine, for each pixel row, a second correction displacement based on the first correction displacement of that pixel row and the cumulative correction displacement. The system may warp each pixel row using the associated second correction displacement and output the warped pixel rows using the display.
