One step ground describes in detail, it is clear that described embodiment is only some embodiments of the present invention rather than whole enforcement
Example.Based on the embodiment in the present invention, those of ordinary skill in the art are obtained under not making creative work premise
All other embodiments, broadly fall into the scope of protection of the invention.
The present invention provides a kind of wear-type virtual reality device, as it is shown in figure 1, include:
Be made up of fore shell 101 and back cover 102 closes housing and is positioned at the mainboard 103, first of described closed housing body
Camber display screen the 104, second camber display screen 105, display/panel bracket 106；
Described mainboard 103 is fixed on described display/panel bracket 106 in the one side of described fore shell 101, is used for processing institute
State the first optics content and second optics of described second camber display screen 105 display of first surface display screen 104 display
Content；
Described first surface display screen 104 and described second camber display screen 105 are fixed on described display/panel bracket 106
In one side away from described back cover 102, and described first surface display screen 104 and described second camber display screen 105 with
Described mainboard 103 connects；
It is additionally provided with the first optical glass 107 and described second optical glass 108 on described back cover 102, is used for passing through
Described first surface display screen 104 watched by first optical glass 107, watches described second curved surface by the second optical glass 108
Display screen 105；
The center of described first surface display screen 104 and described first optical glass 107 are centrally located on same straight line,
The center of described second camber display screen 105 and described second optical glass 108 are centrally located on same straight line.
In embodiments of the present invention, the first optics content can be left eye or the content of right eye that human eye needs viewing, the
Two optics contents can be human eye need viewing left eye or the content of right eye, described left eye or right eye content be input picture or
Obtain after mainboard 103 processes after video.
In embodiments of the present invention, in order to better illustrate in the embodiment of the present invention use first surface display screen 104 with
And the curvature of field and the concept of astigmatism in the beneficial effect that second after camber display screen 105, first explanation prior art.
The astigmatism impact on described wear-type virtual reality device, extra-axial object point light pencil imaging are described as a example by Fig. 2
Time, form two and be mutually perpendicular to and a kind of asymmetry aberration of short-term picture separated by a distance is referred to as astigmatism, in Fig. 2 thoroughly
The edge of mirror can be divided into horizontal edge and the vertical edge of lens of lens according to the primary optical axis of lens, and light path A is for from institute
Stating the collimated light beam that vertical edge is incident, imaging point is meridional focus at V, V, and light path B is from incident the putting down of described horizontal edge
Row light beam, imaging point is sagittal focus at H, H.Meridional focus and sagittal focus are not same points, are astigmatism, and astigmatism is with visual field
Increase and increase rapidly, say, that the imaging at the horizontal direction edge that people is seen by described wear-type virtual reality device
Imaging with vertical direction edge a focus, can not cause soft edge.
The curvature of field impact on described wear-type virtual reality device is described as a example by Fig. 3, and in Fig. 3, light path 1 is and lens light
The parallel paraxial beam of axle incides the light in lens, and light path 2 is that the directional light bigger through the visual field of rims of the lens is incident
Light in lens, the optimal picture point that described light path 1 is formed is O point, and the optimal picture point that light path 2 is formed is T point, rather than and O
Point is at conplane F point, say, that the light optimal imaging point through rims of the lens is with the light near lens centre
Good imaging point is not in approximately the same plane, and i.e. human eye is it is seen that optimal imaging face, is not a vertical O-F plane, but
Curved surface through O-T point.In large visual field optical system, the curvature of field certainly exists so that image objects face the most clearly is not one
Individual plane but a curved surface, and control to affect improperly plus astigmatism, picture quality can be worse.
So causing the unsharp problem of imaging, the present invention to solve astigmatism and the curvature of field present in above prior art
Embodiment employs first surface display screen 104 and the second camber display screen 105, as shown in Figure 4, owing to first surface shows
Display screen 104 and the second camber display screen 105 have certain curvature, A point to be prior art midplane screen in the horizontal direction
Edge point position, B is that C is phase with any on angle of visual field first surface display screen 104 or on the second camber display screen 105 with A
Marginal position with size curve screens, it is seen that the Curved screen of same level size is bigger than the plane screen angle of visual field..
In embodiments of the present invention, due to B relative to A point closer to the first optical glass 107 or the second optical glass
108, define according to aplanatism principle, B point is apparent relative to A point, i.e. improves the one-tenth of described wear-type virtual reality device
Image sharpness.Meanwhile, consider human eye in this visual system the most more sensitive to level ratio, burnt according to sagittal focus and meridian
The position relationship of point, i.e. the curvature of astigmatism parameter adjustment Curved screen, can improve the definition of image planes further.As a example by Fig. 5,
A point is the marginal point on paraxial optimal imaging face, and this is near sagittal focus, but away from meridional focus, its result is that human eye is seen
As the most clear, but vertical direction deforms.And the edge B point of same size Curved screen is relative to A point,
Position is between meridional focus and sagittal focus, say, that decreases the picture point deformation in vertical direction, improves and regard greatly
The definition of image after the match.
