A display device comprising a display module configured to define a display surface. The display module includes a display panel including a plurality of display elements configured to display an image on the display surface. A plurality of diffraction patterns are spaced apart on the display panel at a constant interval. The diffraction patterns are configured to diffract at least some light beams emitted from the plurality of display elements. The plurality of diffraction patterns comprise an organic material.

The present invention includes systems and methods for a multi-primary color system for display. A multi-primary color system increases the number of primary colors available in a color system and color system equipment. Increasing the number of primary colors reduces metameric errors from viewer to viewer. One embodiment of the multi-primary color system includes Red, Green, Blue, Cyan, Yellow, and Magenta primaries. The systems of the present invention maintain compatibility with existing color systems and equipment and provide systems for backwards compatibility with older color systems.

This patent provides a novel stereoscopic imaging system. In the preferred embodiment, the improved stereoscopic imaging system would be incorporated onto a smart phone, which is called the stereoscopic smart phone (SSP). The SSP would work in conjunction with one or more stereoscopic head display units (SHDUs). Once this system is operational, it will allow significant improvements to obtaining stereoscopic imagery. One novel aspect of this patent comprises wherein the stereoscopic cameras on the SSP can move in position to alter stereo separation distance and change the convergence to optimally image a scene.

A method displays a binocular hologram image. The method includes generating a light beam of an incident wave field having coherence, expanding the generated light beam to the size of the active area of a display, converging the expanded light beam on the respective positions of the eyes of a user, generating digital hologram content, and displaying a hologram image based on the converged light beam and on the digital hologram content.

An electronic display includes a display panel that operates in a single display mode to provide a single display, or a dual display mode to provide two displays separated by an inactive region. The electronic display includes the display panel and a panel driver. The display panel includes a left pixel region, a right pixel region, and a middle pixel region between the left and right pixel regions. In the single display mode of the electronic display, the panel driver provides first gate signals generated from first input data to the left, right, and middle pixel regions. In a dual display mode, the panel driver provides second gate signals generated from second input data to the left and right pixel regions. The first input data has a first resolution that is larger than a second resolution of the second input data.

Systems and methods for auto-calibrating a virtual reality (VR) or augmented reality (AR) head-mounted display to a given user with a refractive condition without adding corrective lenses to optical elements of the head-mounted display and without requiring subjective refraction procedures. A method comprises projecting a grid onto an eye of a user using a light source of a head-mounted display worn by the user, capturing the grid as-reflected from the eye using a camera of the head-mounted display, determining a pattern of a reflection of the grid based on the grid as-reflected, generating an aberration map based on a difference between the pattern as-reflected and the grid as-projected, and determining a correction to apply to at least one viewing lens of the head-mounted display worn by the user based on the aberration map.

To reduce burden of a viewer at the time of performing stereoscopic display by a stereoscopic display device and to show a stereoscopic image in a natural and comfortable manner. A disparity estimating unit 210 estimates disparity from the left and right images of an input image to generate a disparity map. A disparity analyzing unit 230 analyzes the disparity map to generate a disparity control parameter for performing suitable disparity control. A disparity control unit 240 controls the content of processing at an image conversion unit 250 in accordance with the disparity control parameter. The image conversion unit 250 performs image conversion on the input image based on the control by the disparity control unit 240 to output an output image. The image conversion unit 250 performs image conversion of two steps. The image conversion unit 250 performs shift processing for shifting the relative positions of the left and right images of the input image in the horizontal direction as first step image conversion, for example. The image conversion unit 250 performs scaling processing for performing enlargement/reduction of the entire screen with each center of the left and right images as a reference, as second step image conversion, for example.

A method for generating stereoscopic light-field data is provided. The method includes the following steps: obtaining three-dimensional image data; performing a multi-view generation process to convert the three-dimensional image data into multi-view data; and performing a light-field conversion process to convert the multi-view data into a stereoscopic light-field pair.

The disclosure describes artificial reality (AR) systems and techniques that enable secure, privacy-preserving device attestation and mutual authentication of multiple devices used concurrently within a multi-device AR system. For example, an AR system comprises a security server configured to generate a pairing certificate that includes information identifying a plurality of devices to be operationally paired with each other. The AR system comprises a peripheral device configured to receive one or more inputs from a user of the AR system, wherein the peripheral device is configured to store the pairing certificate in a non-volatile memory (NVM) of the peripheral device for authenticating the peripheral device and a head-mounted display (HMD) for pairing. The AR system comprises the HMD configured to output artificial reality content, wherein the HMD is configured to store the pairing certificate in a NVM of the HMD for authenticating the HMD device and the peripheral device for pairing.
