The design of sense.When being not required to two picture frame relative angular position relation of regulation, left picture frame 32L and right picture frame 32R can make one
Individual entirety.
The paired column lens 321 of the 3D glasses 32 of this example are the shifting pictures for making the image that display screen is shown produce displacement
Mirror, that is, a kind of optical triangular prism 321a, they are symmetrically installed on the left picture frame 32L of glasses on picture frame median plane O-O
In right picture frame 32R, the bottom surface bottom surface of the prism is arranged on the outside of glasses.Light from display screen 31 is by moving picture
The skew to glasses lateral direction occurs after mirror, human eye sees that center line direction of the virtual image of image on display screen then toward display screen is inclined
Move, the angle of skew allows the virtual image of the two of the people image arrived soon to exist by the distance of distinct vision and display screen of people or so width calculation
It is optimal to be overlapped at the distance of distinct vision.The application of the 3-D view of left and right span mode is watched in 250mm distances with 6 inches of screen mobile phones
Exemplified by device, the long side L about 130mm of display screen, left and right half screen wide each 65mm, the angle of bend of prism used（That is prism
The angle of wedge of tip）α is set to 15 degree, is manufactured with refractive index for 1.5 optical glass or lucite, it is to visible ray refraction angle
Θ is about 7 degree, and display screen is with prism apart from A about 250mm, i.e., the distance of distinct vision of normal Qu Guangdu human eye uses left and right split screen
When pattern watches 3-D view, left and right half screen has the virtual image of the image of subtense angle in viewing human eye to center line on display screen
Offset distance B is about 32.5mm, that is, shields long L a quarter, just coincide together, and sees Fig. 2, is so formed in human brain
Third dimension is tantamount to the effect that naked eyes watch scene, and its superiority is the three-dimensional of all left and right span mode such as the existing VR helmets
Display mode institute is impayable.When mobile phone display screen size and different viewing distance, above geometric parameter need to accordingly change.
In practicality, above parameter is not necessarily very accurate, and two images had both made to be completely superposed, and the vision of people is done finely tunes than VR head on a small quantity
Helmet will easily much.
Embodiment two
Shown in this such as Fig. 3,4,5.In practicality, the three-dimensional display apparatus for having many left and right span mode has several different displays
The selection of ratio, such as combines using extremely wide " ViVO and MPC " in the mobile phone A PP video display playout softwares released
There are several different displaying ratios such as original size, full frame, shearing in the span mode of left and right, original size is by two dimension display
Image narrows down to 1/2nd and is shown in the half screen of left and right by Aspect Ratio is constant, and figure is undistorted but mobile phone of natively very little
Screen area utilization narrows down to a quarter, can hardly see and repay.Full form is to draw to double by the image of original size to make
Be full of display screen, it appears that it is big one times, but ratio serious distortion, to solve this problem, base of this example in embodiment one
