Abstract

The invention discloses a head-mounted 3D display device. The display device comprises a backlight source, a display and a lens, wherein the backlight source is used for supplying quasi parallel light to the display; the display is used for modulating the quasi parallel light emitted by the backlight source and projecting the modulated light to the lens; the lens is used for converting the modulated light to parallel light and projecting the parallel light to human eyes. The head-mounted 3D display device realizes an augmented reality effect by a single reflection and enlarges a field angle through the single aspherical half-reflection lens. Since extra lenses are eliminated, the head-mounted 3D display device has a simple and compact optical structure, and the efficiency for solar energy utilization and the portability of the head-mounted display are improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a head-mounted three-dimensional display device based on single reflection. Background technique [0002] Head-mounted displays, also known as near-eye displays, enable users wearing the head-mounted display device to see near-eye content. Head-mounted display devices were initially mainly used in military and scientific research fields. With the popularization of electronic technology and the development of lens manufacturing technology, head-mounted display devices gradually entered people's lives. [0003] Existing head-mounted display devices include non-transmissive and transmissive types. Among them, the non-transmissive head-mounted display device uses a lens to image the display content that is very close to the human eye within the focusing range of the human eye, so that the The human eye can clearly see the content on the display; the transmissive head-mounted displa...
