Description
Technical field
The present invention relates to display device technology field, more particularly to a kind of head-mounted display apparatus.
Background technology
Using the head-mounted display of video transmission-type technology, main two lens groups by being arranged side by side and structure is identical
Part and corresponding display unit are implemented as picture, and device configuration has a front camera, and equipment is by the information and virtual information of shooting
Being shown after fusion in display unit, the virtual image that display unit zooms into upright amplification by lens subassembly is implemented as picture, and visual angle is big,
But since influx and the adjusting reason such as contradiction, equipment operating lag are also easy to produce spinning sensation, and the augmented reality head of video transmission-type
Head mounted displays are of a relatively high to the requirement of computer graphical arithmetic speed, and cost is higher.
Using the transmission-type head-mounted display of guide technology, its waveguides sections is mainly by being coupled into part, hop, coupling
Go out part three parts composition, i.e.,：The light of electronic display unit enters waveguide by modes such as grating, sawtooth, free form surfaces,
By transmission, then waveguide is exported in a manner of grating, sawtooth, free form surface etc., into the eyes of observer.Realize using this technology
Head-mounted display visual angle it is small and cost is higher, visual angle is below 60 degree and mostly at 40 degree or so.With using planar array
Train wave leads the transmission-type head-mounted display citing of Display Technique, and to reduce ghost image, its semi-transparent membrane array coating layers is more, and array is put down
Row degree requires height, and technology difficulty is big, is also easy to produce ghost image, and yields is low, of high cost.
Using the head-mounted display of prism technique, the mode mainly combined by lens group, concave mirror or both is put
Big display unit, then pass through the mode catoptric imaging such as Amici prism or reflecting prism.Human eye only sees the display unit figure of amplification
Picture, or the display unit image and surrounding environment of display amplification can be seen at the same time.The head-mounted display realized using this technology
Visual angle is smaller and mostly below 40 degree, and increase visual angle can seriously increase weight of equipment.
Using the head-mounted display of free form surface technology, display unit is directly over free form surface catoptric imaging or display
Unit is transmitted through lens group, free form surface catoptric imaging.Realized using offset lens and see that surrounding environment and display are single at the same time
The effect of first display content, also can by blocking, plated film or directly only observe display unit in modes such as metal surface processing and show
The content shown.The head-mounted display realized using this technology is there are free form surface yields is low, and technology difficulty is big, non-defective unit cost
The problem of high.
Using the head-mounted display of optical field imaging technology, whether by microlens array technology or optical fiber scanning battle array
Row technology or other micro structure array technologies, to present compared with high imaging quality, and realize dynamic effect, all to computing requirement
It is higher, further result in the more demanding of processor, cause cost higher.
Using the head-mounted display of retinal projection's technology, by lens or lens group to light source beam-expanding collimation so that
Light beam is modulated by each modulation unit of spatial light modulator (LCD, LCOS, DMD etc.) so that is emitted from each pixel
Light be single beam, and be parallel to each other, pupil center then converged at by optical system, images in retina afterwards.
The big various visual angles of head-mounted display using this technology are smaller.
The head-mounted display of non-transmissive Display Technique, mainly two lens subassemblies by being arranged side by side and structure is identical
And corresponding display unit is implemented as picture, since influx and the adjusting reason such as contradiction, equipment operating lag are also easy to produce spinning sensation.
The content of the invention
For this reason, an object of the present invention is to provide a kind of assembly precision require it is low, cost is low, the big wear-type in visual angle
Display device.
The present invention provides a kind of head-mounted display apparatus, including：Sandwich type element is worn, described wear in sandwich type element is provided with
Display device, upper reflector, lens and lower speculum；The reflecting surface of the display unit of the display device and the upper reflector
Between there is angle, the upper reflector reflects the light of the display unit of the display device, and the lens are arranged on described
Between upper reflector and lower speculum, the reflection light of the upper reflector reflects after passing through the lens through the lower speculum
Into the eye of user, when user wears, the lower speculum is located at the front of eyes of user.
In the present invention, the light of the display unit of display device is after upper reflector reflects, through lens, by lens pair
Light is adjusted, and is most reflected afterwards through lower speculum, and when user wears, lower speculum is located at the front of eyes of user, Yong Huke
To see the picture of display unit after treatment from lower speculum, present apparatus equipment is simple, low manufacture cost, and visual angle is big.
Further, the angle between the display unit of the display device and the lens is 60 ° -120 °, accordingly
Angle between the reflecting surface of the upper reflector and the display unit of the display device is 60 ° -30 °.
Further, what the lower speculum was rotatably connected on the downside of the lens described wears on sandwich type element.
Further, the upper reflector and lower speculum are front surface mirror.
Further, the shape of the upper reflector and/or the lower speculum is trapezoidal, the lower speculum with it is described
Wear and be provided with angle limiting structure at the position of sandwich type element connection.
Further, the lower speculum is specular reflective mirrors or fractional transmission partially reflecting mirror.
Further, the display device is 2D display devices or 3D display device.
