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.

A device for adjusting interpupillary distance is provided. The device for adjusting interpupillary distance includes an adjustment bottom, a housing, and an adjustment support. The housing is disposed on the adjustment bottom. The housing includes a base, a holder, and a deformation part disposed between the base and the holder. The holder moves relative to the base via the deformation part. The adjustment support is connected to the holder and the adjustment bottom.

A wearable display apparatus has a headset for display from left-eye and right-eye near-eye catadioptric pupil-forming optical systems, each defining an exit pupil. Each optical system has an image generator to direct image-bearing light for a 2D image from an emissive surface. A curved reflective surface along the view axis is partially transmissive and defines a curved intermediate focal surface. A beam splitter reflects light toward the curved reflective surface. An image relay optically conjugates the formed image with a curved aerial image formed in air at the curved intermediate focal surface. The image relay has a prism having an input surface facing the emissive surface of the image generator, an output surface facing the curved intermediate focal surface, and a folding surface between input and output surfaces for folding the optical path for light generated by the image generator. An aperture stop for the relay is within the prism.

A head mounted display (HMD) includes an electronic display, an optical element, and a light sensor. The electronic display is configured to generate a pixel pattern of display light and the optical element is disposed to pass the display light to a user of the HMD. The light sensor is disposed proximate to the optical element to generate light measurements in response to the pixel pattern. The light measurements are representative of a lateral position of the optical element with respect to the electronic display.

A head-mounted display apparatus configured to be worn by a viewer. The apparatus includes a pair of display modules moveably coupled to a curved rail, the display modules configured to project stereoscopic images toward the viewer, wherein a first one of the display modules projects a first stereoscopic image and a second one of the display modules projects a second stereoscopic image, the first and second stereoscopic images creating a single unified virtual stereo image that converges at a predetermined convergence distance in front of the viewer. The apparatus further includes an adjustment mechanism configured to move each of the display modules along the curved rail symmetrically about a midpoint of the rail, thereby varying a distance between the display modules while maintaining the predetermined convergence distance.

Stereoscopic viewing systems may be adjusted for a user's inter-pupillary distance (IPD). An inter-pupillary distance (IPD) value is determined from a signal from a position sensitive device coupled to two moveable sighting fixtures mounted to a head mounted display (HMD) having two fixed optics configured for a specific inter-pupillary distance. The position sensitive device is configured to produce a signal that corresponds to a distance between the two sighting fixtures. The images are warped with a processor to optimize display of the images with the two fixed optics for the determined IPD value.

A head-mounted display device includes a see-though display providing both eyes of a user with a view of a physical object, a processor, and a non-volatile storage device holding instructions executable by the processor to: display an image that corresponds to the physical object to a first eye of the user at an offset to the physical object; display blocking light to a second eye of the user; in response to alignment user input, move a position of the image relative to the physical object; in response to completion user input, determine the inter-pupillary distance of the user; and calibrate the head-mounted display device based on the inter-pupillary distance.
