Head-mounted see-through display device

Abstract

The invention discloses a head-mounted see through display which comprises a head-mounted body. The head-mounted body comprises a peak body arranged in the front of the forehead, a display screen and a half-transparent half-reflection lens; the front end of the peak body is provided with a hinge; the half-transparent half-reflection lens is arranged below the front end of the peak body through the hinge in an angle-adjustable mode; the display screen is fixed in the peak body and the display surface of the display screen is matched with the center of the half-transparent half-reflection lens; image light of the display screen is projected onto the half-transparent half-reflection lens; and the half-transparent half-reflection lens projects the received image light of the display screen and environmental light passing through the half-transparent half-reflection lens to human eyes to image. The head-mounted see through display has a simple structure and good display stability and is suitable for different environment illumination intensities; applicability is improved to a certain extent; combination of immersion and augmented reality of a head-mounted intelligent display system is implemented; and interaction and real-time interaction are improved.

Description

technical field [0001] The invention belongs to the technical field of head-mounted displays, and in particular relates to a head-mounted see-through display device. Background technique [0002] Head-mounted displays in the prior art mainly include a single-channel fully shielded direct-view type and a dual-channel see-through environment superimposition type. The dual-channel see-through environment superposition type is suitable for wearable smart devices, but it cannot be used in sunlight, and the environment superposition is difficult to identify display images Details such as textures in text and pictures, the single-channel fully shielded direct-view type can adapt to ambient light, but most displays have to block the important field of view of the environment, and the display area cannot be enlarged; in most wearable smart device head-mounted displays, most It is a single-eye display, because the volume and weight of the double-eye dual-screen solution are difficult ...

[0002] Head-mounted displays in the prior art mainly include a single-channel fully shielded direct-view type and a dual-channel see-through environment superimposition type. The dual-channel see-through environment superposition type is suitable for wearable smart devices, but it cannot be used in sunlight, and the environment superposition is difficult to identify display images Details such as textures in text and pictures, the single-channel fully shielded direct-view type can adapt to ambient light, but most displays have to block the important field of view of the environment, and the display area cannot be enlarged; in most wearable smart device head-mounted displays, most It is a single-eye display, because the volume and weight of the double-eye dual-screen solution are difficult to be portable and wearable, and the split-screen structure is unstable during exercise, resulting in unstable three-dimensional display, poor user experience, and difficult appearance; therefore, the existing technology has defects and needs to be solved for further improvement and development
