Embodiment Construction

[0054] Embodiments of the present invention will now be described with reference to the drawings, wherein like reference numerals are used to refer to like elements throughout. It should be understood that the drawings are not necessarily drawn to scale.

[0055] In general, one aspect of the invention is a head mounted display (HMD) system having an enhanced image panel configuration combined with an optimal adjustment mechanism. In an exemplary embodiment, an HMD system includes an optical device; at least one movable image panel, wherein the optical device directs image light from the movable image panel along a first optical path; a fixed image panel, wherein light emitted from the fixed image panel A portion of the image light of the optical device is combined with the image light of at least one movable image panel; The optics and movable image panel adjust an interpupillary distance (IPD) of the HMD system; wherein the adjustment to the IPD does not alter the first opt...

Abstract

A head-mounted display (HMD) system includes an optical arrangement; at least one moveable image panel, wherein the optical arrangement directs image light from the moveable image panel along a first optical pathway; a fixed image panel, wherein a portion of image light emitted from the fixed image panel is combined with image light of the at least one moveable image panel by the optical arrangement; and an adjustment mechanism that is configured to adjust an interpupillary distance (IPD) of the HMD system by moving the optical arrangement and the moveable image panel relative to the fixed image panel between a first position and a second position corresponding to different IPDs. The adjustment to the IPD maintains the first optical pathway. The HMD system further may include a sensing module that measures an adjustment position of the optical arrangement, and control electronics configured that determines the IPD based on the measured adjustment position, and updates image light emitted by the fixed image panel based on the IPD.

Description

technical field [0001] The present invention can be applied to the field of compact wearable displays, especially Head-Mounted Display (HMD) systems for applications such as virtual reality and augmented reality. Background technique [0002] HMD systems are a type of wearable device that is gaining popularity in the consumer electronics industry. HMDs and similar devices such as helmet-mounted displays, smart glasses, and virtual reality headsets allow users to wear the display device such that the hardware remains fixed to their head regardless of the user's movements. [0003] When combined with environmental sensors such as cameras, accelerometers, gyroscopes, compasses, and light meters, HMDs can provide users with virtual and augmented reality experiences. Virtual reality (Virtual Reality, VR) allows users to immerse themselves in a virtual world, where everything the user sees comes from a display device. A device providing Augmented Reality (AR) allows a user to se...
