A head-mounted display system includes a head-mounted display unit a display that, in use, is held in an operational position over a user's face. The head-mounted display system further comprises a flow generator configured to generate a flow of air, and an air guide arrangement coupled to the flow generator to enable the flow generator to direct air to, or draw air from, one or more selected areas in proximity of the head-mounted display system.

A method includes separately exposing selected portions of a first rigid substrate and a second rigid substrate to laser radiation, selectively etching the exposed portions of the first rigid substrate and the second rigid substrate using a chemical etchant and bonding the first rigid substrate to the second rigid substrate along a common interface to form a fluidic valve. The fluidic valve may be coupled to a fluidic haptics device, for example, which may be integrated into an artificial reality system.

In a linked display system in which wireless communication connection between a first information device and a second information device has been established, when the first information device transmits text data to the second information device in a state of displaying content containing the text data and image data, the second information device displays the text data while the first information device stops displaying the text data and enlarges and displays the image data.

The embodiments of the disclosure provide a method for dynamically controlling shooting parameters of a camera and a tracking device. The method includes: determining a plurality of time frames, wherein the time frames include a plurality of first time frames and a plurality of second time frames; controlling the camera of the tracking device to shoot a first image with a first exposure parameter in each of the first time frames and accordingly performing an environment detection; controlling the camera of the tracking device to shoot a second image with a second exposure parameter in each of the second time frames and accordingly performing a first specific detection, wherein the second exposure parameter is lower than the first exposure parameter.

An interfacing structure for a head-mounted display system with a head-mounted display unit having a display and a positioning and stabilising structure structured and arranged to hold the head-mounted display unit in an operable position on a user's head in use, includes a face engaging portion configured to engage around a periphery of an eye region of the user's face in use, the face engaging portion being flexible and resilient and including at least one face engaging flange forming at least one closed loop portion having an enclosed cross section, the face engaging flange being shaped to form an enclosed loop in cross section to form the closed loop portion, the closed loop portion of the face engaging flange being integrally formed in a continuous loop.

Provided are a design method of a display device, a display device and a near-eye display apparatus. The display device includes a substrate, light-emitting elements and a light adjustment layer. The light-emitting elements are located on one side of the substrate and facing a light-emitting surface of the display device, and a pixel opening is configured in each light-emitting element. The light adjustment layer is located on one side of the light-emitting elements away from the substrate. The light adjustment layer includes at least one microlens array and a light-transmitting layer located on one side of the microlens array away from the substrate and covering the microlens array, the microlens array includes at least one microlens unit, and a refractive index of the at least one microlens unit is greater than a refractive index of the light-transmitting layer.

Rear-view image(s) of a region of a surrounding environment that is behind a vehicle, is/are captured, by utilising rear-view camera(s). An image to be displayed via the heads-up display, is generated, wherein when generating the image, processor(s) is/are configured to generate an image segment of the image by utilising the rear-view image(s) of said region of the surrounding environment. The image is displayed via the heads-up display for producing a synthetic light field augmenting a real-world light field incoming via a windshield of the vehicle.

A display device includes: a display panel that includes, in a front surface, a display area in which an image is displayed, and projects, from the display area, light that has entered from a back surface as display light showing the image; a thermal conductive sheet that is disposed contacting the display panel, and has an opening positionally corresponding with the display area; and a light transmissive material that sandwiches the thermal conductive sheet together with the display panel.

A head-mounted device may include a housing with a display that displays images that are viewable from an eye box. A light seal may be coupled the housing and may block outside light from reaching the eye box. The light seal may include a seamless tube of knit fabric that forms an outermost layer of the light seal. A light-blocking fabric may line the inner surface of the seamless tube of knit fabric. The light-blocking fabric may include a dark-colored weft knit layer facing the eye box, a light-colored weft knit layer facing and matching a color of the seamless tube of knit fabric, and a middle layer joining the light-colored weft knit layer and the dark-colored weft knit layer. The dark-colored weft knit layer may ensure sufficient opacity without being visible through the seamless tube of knit fabric.
