Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0032] In view of the fact that none of the above-mentioned existing technologies can realize the adjustment of the pixel-level see-through rate, the inventor of the present invention thought of using a single pixel-level control screen to control the see-through rate (the see-through rate is the transmittance, see-through If the rate is high, the reflectance is low). The display screen for controlling the transmittance at the pixel level may be any existing or fut...

Abstract

The invention discloses a see-through rate adjustable head mounted display device. The see-through rate adjustable head mounted display device comprises a main body frame, a camera, an optical system, a control system and a micro display group; the micro display group comprises two overlapped transparent display screens; the first display screen is used for displaying CGIs (Computer Generation Image); the second display screen which is a pixel-level see-through rate controlled display screen is used for controlling the see-through rate of the micro display group; the first display screen is located on the close-to-eye side of the second display screen. According to the see-through rate adjustable head mounted display device, the see-through rate of an HMD (Head Mounted Display) is adjusted through the second display screen which overlaps with a CGI display screen and every pixel of the second display screen can be individually controlled, so that control on the pixel-level see-through rate can be achieved, the requirements for comfort, clarity and the like of the HMD of users can be furthest met, the eye fatigue feeling which is produced in the using process of the HMD is reduced, and the availability of the HMD is greatly removed.

Description

technical field [0001] The present invention relates to the field of wearable computing head-mounted display devices, in particular to a head-mounted display device with adjustable see-through ratio. Background technique [0002] A head-mounted display (HMD, Head mounted display), also known as a head-up display (HUD, Head up display), is a device that includes at least one micro-display device (image source system), corresponding optical system, and support structure (support system). Near-eye display device. See-through HMD has its special human-computer interaction characteristics, can be combined with augmented reality technology, and is widely used in scientific research, military, industry, games, video, education, simulation and other fields. The see-through rate describes the see-through effect of the see-through HMD. Under different lighting environments, whether the see-through rate is appropriate directly determines the user experience of the HMD. Existing see-t...
