A display method of an image is disclosed. A position of a vergence surface of a user is obtained through a gaze tracking device. An image is provided by a display, the image is located at a virtual image surface, and the image has an offset between different view directions. A controller is coupled to the gaze tracking device and the display. The controller receives an information of the position of the vergence surface obtained through the gaze tracking device, performs an algorithm processing according to the information to obtain the offset, and transmits a display information including the offset to the display. An eye of the user focuses on an accommodation surface when viewing the image, and a position of the accommodation surface is different from a position of the virtual image surface.

A mixed reality accommodation system and related methods are provided. In one example, a head-mounted display device includes a plurality of sensors and a display system for presenting holographic objects. A mixed reality safety program is configured to receive a holographic object and associated content provider ID from a source. The program assigns a trust level to the object based on the content provider ID. If the trust level is less than a threshold, the object is displayed according to a first set of safety rules that provide a protective level of display restrictions. If the trust level is greater than or equal to the threshold, the object is displayed according to a second set of safety rules that provide a permissive level of display restrictions that are less than the protective level of display restrictions.

An endoscope includes two or more imaging modules having a lens barrel containing an optical system, an image sensor, and a sensor holding member that relatively fixes the lens barrel and the image sensor, a sub-frame that relatively fixes each of the two or more imaging modules, and an outer shell portion that accommodates and fixes the sub-frame and the two or more imaging modules.

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.

Some implementations of the disclosure are directed to tessellating a light field into a size or depth that is larger or further extended than the pupil size of an imaging system or display system. In some implementations, a display system comprises: a display configured to emit light corresponding to an image; a first optical component positioned in front of the display, the first optical component configured to pass the light to an orthogonal field evolving cavity (OFEC) at a plurality of different angles; the OFEC, wherein the OFEC comprises a plurality of reflectors that are configured to reflect the light passed at the plurality of different angles to tessellate the size of the image to form a tessellated image; and a second optical component optically coupled to the OFEC, the second optical component configured to relay the tessellated image through an exit pupil of the display system.

In this patent, an advanced head display unit designed primarily for fire fighters is disclosed. The advanced augmented reality/virtual reality (AR/VR) head display unit improves coordination between teammates through eye tracking coupled with augmented reality features. This allows one fire fighter to know where another fire fighter is looking and helps coordinate tasks by dividing the scene into sectors and visibly marking each sector. Further, this system helps determine where to hose with a smart target system. Further, multiple sensors are utilized together to triangulate the location of a victim's voice. Additional advantages are also disclosed above.

A spatial light modulator (SLM) includes a first liquid crystal panel and a second liquid crystal panel that are oppositely configured, and a polarization adjustment part configured between the first liquid crystal panel and the second liquid crystal panel. An alignment direction of the first liquid crystal panel is parallel to an alignment direction of the second liquid crystal panel. The first liquid crystal panel is configured to perform a phase modulation on incident linear-polarized light. The polarization adjustment part is configured to rotate, by a preset angle, a polarization direction of linear-polarized light exited from the first liquid crystal panel. The second liquid crystal panel is configured to adjust a polarization state of linear-polarized light exited from the polarization adjustment part to adjust an amplitude of exited light.

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. An autorefractor assembly of the head-mounted display, or a separate autorefractor headset, measures refractive error and communicates the measurements to a control system of the head-mounted display. Based on the refractive error measurements, the head-mounted display can adjust adaptive lenses and other adaptive optics to modify transmitted images; can make compensating adjustments to images displayed by a stereoscopic display device of the head-mounted display; or can make both types of adjustment. These automatic calibrations correct displayed images to compensate for refractive aberration in one or both eyes of the user. In an embodiment, the head-mounted display can correct other vision defects of the given user measured by objective ophthalmic examination.

A display device is provided. The display device includes at least one virtual object image source, at least one display device for displaying a virtual object image, and at least one variable lens. The at least one variable lens includes at least two variable optical cells.
