Disclosed are a head mounted display (HMD), and a method for controlling the same. The HMD includes: a body having a display unit; a lens driving unit provided at the body, and configured to move a lens unit spaced apart from the display unit, wherein the lens driving unit includes: a lens frame having a first tube portion protruded in a first direction, and coupled to the body; a lens housing having a second tube portion protruded in the first direction and having the lens unit, the second tube portion relatively moved on the first tube portion; a link unit coupled to the lens frame and the lens housing, and configured to move the lens housing; and a driving unit provided at one side of the first tube portion, and configured to operate the link unit.

A headset includes a housing, an optical assembly disposed in the housing, and an adjustment assembly coupling the optical assembly to the housing. The optical assembly includes a first lens and a second lens spaced from the first lens by a first distance. The adjustment assembly includes an interpupillary distance adjustment mechanism and an eye relief distance adjustment mechanism. The interpupillary distance adjustment mechanism is configured to adjust the first distance between the first lens and the second lens along a first axis. The eye relief distance adjustment mechanism configured to adjust the optical assembly a second distance along a second axis orthogonal to the first axis.

A packaging structure of head mounted terminal and a head mounted terminal are disclosed. The packaging structure comprises an annular rear casing and a soft rubber member, and the soft rubber member is disposed between the rear casing and two lenses of the head mounted terminal. The outer edge of the soft rubber member is fixed on the inner ring of the rear casing, the soft rubber member comprises two lens barrels arranged symmetrically, and the two lens barrels are respectively sleeved on the two lenses of the head mounted terminal. The soft rubber member further comprises an extending and folding part disposed on an outer periphery of the lens barrel, which is used to realize the extension of the lens barrel with the left and right movement of the lens.

A head-mounted device may have optical modules that present images to a user's eyes. Each optical module may have a lens barrel with a display and a lens that presents an image from the display to a corresponding eye box. To accommodate users with different interpupillary distances, the optical modules may be slidably coupled to guide members such as guide rods. Actuators may slide the optical modules towards or away from each other along the guide rods. The guide rods may be formed from fiber-composite tubes with end caps that are fastened to a frame in the head-mounted device. The tubes may be partly or completely filled with cores to add strength. Low-friction coatings such as metal coatings may be formed on the fiber-composite tubes and the corresponding inner surfaces of the optical module structures that slidably engage the fiber-composite tubes.

A night vision system having one or more pods to permit a user to see in reduced light or evening conditions. The night vision system can include one or more pod(s) and the pod(s) can be actuatable between an “up” position and an active “down” position, wherein the pod is automatically powered and controlled when in the active position. A wearable power and/or control pack is further described, as is the use of an interpupillary stop feature.

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.
