A head-mounted display device

Abstract

The invention relates to the display apparatus field and provides a head-mounted display apparatus. The display apparatus comprises a screen cover, a lens shade, lenses and a dust cover. The dust cover is fixed to the screen cover and covers the screen cover and at least one part of head lens shade. A position on the dust cover, which is close to the lens, is provided with two through holes. The lens shade penetrates the through holes. Because the dust cover covers the screen cover and the at least one part of lens shade, when the lens shade is moved towards left and right sides so as to change a distance between the two lenses during pupil distance adjusting, the dust cover covers a motion gap between the lens shade and the screen cover, which is generated because of left and right movements of the lens shade, therefore, dust can be prevented from entering into an optical system and adhere to surfaces of a display screen and the lenses, and then amplified dust particles can be avoided from seeing through the lenses, and an immersed experience and an ornamental effect of a user when using the head-mounted display apparatus are improved.

Description

technical field [0001] The present invention relates to the field of display devices, in particular to a head-mounted display device. Background technique [0002] A virtual reality device is a display device that is worn on the user's head and can directly form a display image in front of the user's eyes when the user experiences the virtual world through a computer simulation system. It can provide users with stereoscopic vision and improve viewing experience. Currently, the most common virtual reality devices mainly include a virtual reality helmet and a head-mounted display (HMD, referred to as a head-mounted display). [0003] The head-mounted display includes a head-mounted display that does not support interpupillary distance adjustment and a head-mounted display that supports interpupillary distance adjustment. For a head-mounted display that supports interpupillary distance adjustment, it includes a display screen component and is arranged on the display screen with...

[0003] The head-mounted display includes a head-mounted display that does not support interpupillary distance adjustment and a head-mounted display that supports interpupillary distance adjustment. For a head-mounted display that supports interpupillary distance adjustment, it includes a display screen component and is arranged on the display screen with the Lens components corresponding to the user's left and right eyes, such as figure 1 As shown, when adjusting the interpupillary distance, the lens cover 03 is moved left and right to change the distance between the two lenses 04 to achieve interpupillary distance adjustment, and due to the left and right movement of the lens cover 03, the distance between the lens cover 03 and the screen cover 01 There is a relative displacement between the lens cover and the screen cover, and there is a movement gap 02 between the lens cover and the screen cover, and the dust will directly enter the optical system through the movement gap 02 and adhere to the surface of the screen and the lens 04, resulting in a magnified view through the lens 04 Therefore, it is particularly important to provide a dust cover capable of sealing dust and facilitating interpupillary distance adjustment and a head-mounted display device with the dust cover
