A video display device includes: a display element displaying images by modulating light from an illumination optical system; and an eyepiece optical system guiding image light from the display element into an optical pupil. The illumination optical system includes: a light source including light emission points arranged substantially linearly; a diffuser plate diffusing illumination light from the light source in a first direction, in which the light emission points are arranged, but not in a second direction perpendicular to the first direction; and an optical element bending the illumination light such that the optical pupil and the light source are substantially conjugate. The optical element includes an illumination mirror, a reflection surface thereof having a non-zero curvature in all sections including a normal line at the optical-axis intersection. Here, the section perpendicular to the first direction has a different curvature from the section perpendicular to the second direction.

The problem addressed by the present invention is to provide a head up display device capable of counteracting sunlight without using a shutter or a reflection type polarizing film. A first concave mirror has a curvature to cause the reflected display light to intersect vertically before reaching a second mirror, and a second concave mirror serves to reflect the received display light. A case is provided with a first shield and a second shield extending near an intersecting point to sandwich a light path between the first and second concave mirrors. The first and second shields can block external light entering into the case from outside the case and proceeding toward the first concave mirror after being reflected from the second concave mirror.

A head-mounted display device includes a display element with a two-dimensional array of pixels, and an enclosure at least partially enclosing the display element. The head-mounted display device also includes a plurality of light sources located on the enclosure for determining a position of the head-mounted display device. Each light source of the plurality of light sources is uniquely identifiable based at least in part on light emitted by the light source.

DUAL-AXIS TILT PLATFORM FOR HEAD MOUNTED DISPLAY

A tilt platform for use in an HMD comprises a monolithic spring structure including a first outer planar structure, a second outer planar structure, a middle planar structure disposed between the first and second outer planar structures, a first hinge structure coupling the first outer planar structure and the middle planar structure to each other, and a second hinge structure coupling the second outer planar structure and the middle planar structure to each other. The first and second hinge structures have respective first and second hinge axes that are orthogonal to each other. The tilt platform further comprises a first adjustment mechanism configured for tilting the first outer planar structure and the middle planar structure relative to each other about the first hinge axis, and a second adjustment mechanism configured for tilting the second outer planar structure and the middle planar structure relative to each other about the second hinge axis.

Microdisplay based immersive headset

An immersive headset device is provided that includes a display portion and a body portion. The display portion may include microdisplays having a compact size. The microdisplays may be movable (e.g., rotational) relative to the body portion and can be moved (e.g., rotated) between a flipped-up position and a flipped-down position. In some instances, when the microdisplays are flipped up, the headset provides an augmented reality (AR) mode to a user, and when the microdisplays are flipped down, the headset provide a virtual reality (VR) mode to the user. In certain implementations, the headset includes an electronics source module to provide power and/or signal to the microdisplays. The electronics source module can be attached to a rear of the body portion in order to provide advantageous weight distribution about the head of the user.

Extended reality headset positioning and stabilization

An extended reality headset is configured to position and stabilize the headset on a face when worn. For example, the headset can include an external frame with first and second side pieces coupled to a display structure and configured to provide lateral stabilization. In some examples, the headset can include a front head-engaging structure front head-engaging structure that is rotationally coupled to the external frame via a pivot point. The headset can also include a rear head-engaging structure coupled the external frame. In some examples, the rear head-engaging structure can include a tensioning mechanism to adjust the headset to fit various head shapes. Additionally, the headset can include a flexible strap coupled to the front head-engaging structure and the tensioning mechanism. In some examples, applying tension to the flexible strap by the tensioning mechanism can cause the front head-engaging structure to rotate along the pivot point, providing a secure fit.
