Abstract
The invention discloses a nondestructive grating autostereoscopic display screen. The nondestructive grating autostereoscopic display screen comprises a display screen and gratings, wherein the display screen completely displays left and right pictures, namely displays left and right complete pictures according to the number of transverse pixel points of the display screen and the original ratio of the odd pixel points to the even pixel points; the number of the effective gratings positioned in the front of the display screen is consistent with that of the transverse pixel points of the left or right picture on the screen; the effective gratings positioned in the front of the display screen correspond to the transverse pixel points of the left or right picture on the screen; and according to the size and the arrangement distance of the effective gratings, a person at certain position in front of the effective gratings can see the complete right picture on the display screen but not the left picture by the right eye, and can see the complete left picture on the display screen but not the right picture by the left eye. The nondestructive grating autostereoscopic display screen can solve the technical problem that people can see the nondestructive stereo image with naked eyes.
Description
Technical field
The present invention relates to a kind of stereoscopic imaging apparatus.
Background technology
Existing domestic and international stereo display method has methods such as fixed grating, aberration, polarized light, stroboscopic.These methods have the loss more than at least 50% all.The overwhelming majority wants wear a pair of spectacles just can see stereoeffect, see that the stereoeffect of loss more than 50% arranged even there is other bore hole technology also can only see through grating.Not harmless both at home and abroad at present grating bore hole stereo display screen products occurs.
Summary of the invention
The purpose of this invention is to provide a kind of harmless grating bore hole stereoscopic display screen, to have solved the technical matters that people's bore hole is watched the stereo-picture that does not have loss.
In order to realize the foregoing invention purpose, the technical scheme that the present invention adopted is following:
A kind of harmless optical grating three-dimensional display screen; It comprises display screen and grating two parts; It is characterized in that the complete successively demonstration of display screen left and right sides picture; Promptly press the number of the horizontal video beam point of display screen, press former ratio with the odd and even number video beam and show complete left and right image frame, it is consistent also corresponding that quantity and the screen that is positioned at effective grating in display screen the place ahead gone up the number of horizontal video beam point of the left side that occurs or right picture; The size of this effective grating and the distance of arranging make the people who is positioned at certain position place, effective grating front, and right eye can only be seen right pictures whole on the display screen, and can't see left picture, and left eye can only be seen left pictures whole on the display screen, can't see right picture.Described display screen and grating are flat board or globoidal structure.
With left and right two paths of signals, receive on the display screen through converter, in the left and right picture of the complete demonstration of former ratio, the number of promptly pressing the horizontal video beam point of display screen shows complete left and right image frame with odd and even number video beam point on display screen.
Display screen and grating specifically are provided with parameter and can obtain through following formula:
Calculate grating apart from the H value
Grating is looked interval S apart from H=luminous point centre distance P * imaging apart from G/ beholder eyes;
Calculate effective raster width Y value
Imaging is apart from G/ (forming images apart from the G+ grating apart from H)=X/Q;
Screen width W=2Q+ beholder eyes are looked interval S;
Effectively raster width Y=2X+ beholder eyes are looked interval S;
Calculate single raster width K value and grating gap width R value
The lateral luminous pipe of the single effective raster width Y/ of raster width K=grating gap width R=is counted the doubly effective raster count M of the effective raster width Y/2 of N=;
Above unit is mm.
Advantage of the present invention is to realize that people's left eye before screen can see complete left picture; Right eye can be seen complete right picture; The effect of grating is to make people's right eye can't see left picture, and left eye can't see right picture, and promptly the people can bore hole see the stereoscopic picture plane that has no loss.

Fig. 5 be grating of the present invention and display screen the parameter synoptic diagram is set.
Fig. 6 be the effective raster width of the present invention the parameter synoptic diagram is set.
Number among the figure: the 1st, display screen, the 2nd, grating, the 3rd, left eye, the 4th, right eye, the 5th, effective grating.
Embodiment
Details are as follows for concrete structure of the present invention and principle:
Dark color among Fig. 1, light rectangle are represented three-in-one luminotron.Wherein all light rectangles are formed a group of pictures A, with a cover controller control.All dark rectangles are formed another group of pictures B, with another set of controller control.I.e. simultaneously synchronous playing two-way DVI or other vision signals on a display screen.
Adopt luminotron to constitute display screen in the present embodiment, be lateral luminous pipe number so horizontal video beam is counted.
Fig. 2 is described to be the stereo display principle and the structural drawing of panel display screen 1 and effective grating 5.Wherein display screen 1 is plate with effective grating 5.Be positioned at display screen 1 the place ahead that shows complete left and right sides image frame and be provided with effective grating 5, effectively a left side or right picture occur on the quantity of grating 5 and the screen 1 luminous count consistent also corresponding; The size of this effective grating and the distance of arranging; Make the people who is positioned at certain position place, effective grating 5 front, right eye 4 can only be seen right pictures all on the display screen 1, and can't see left picture; Left eye 3 can only be seen left pictures all on the display screen 1, can't see right picture.
Fig. 3 is described to be the stereo display principle and the structural drawing of arc-surface display screen and effective grating.Wherein display screen is cabochon with effective grating.Design concept is consistent with effective grating with above-mentioned plate display screen.
More concrete below description image-forming principle of the present invention:
It is to be confirmed by the distance of grating and screen that the people watches the optimum position of screen, and the effective distance dependent of the adjacent luminous point of the interpupillary distance of the distance of grating and screen and human eye and screen.The people watches the optimum position of screen is according to setting up the on-the-spot area in screen the place ahead, the position with need to confirm, effectively the distance between grating and the screen can obtain optimum efficiency through on-the-spot adjustment.
Referring to Fig. 4, variant and can see through left and right two width of cloth pictures that the luminous point on the screen that grating sees is formed because of the interpupillary distance of human eye, therefore on a lot of angles and position, can both see the stereoscopic picture plane that has no loss.
Bionical and the physical optics principle according to human eye, screen, geometry symmetry and similarity relation between grating and the beholder position in order to obtain best 3D viewing effect, need find the optimum position of grating.The present invention has the method that obtains best grating, just lists here and lifts wherein computing method as explanation.
Referring to Fig. 5,6, enumerate a kind of computing method of harmless grating bore hole stereoscopic display screen below: the first step: calculate grating apart from H value (mm)
H＝PG/S
Second step: calculate effective raster width Y value (mm)
G/(G+H)＝X/Q W＝2Q+S Y＝2X+S
The 3rd step: calculate single raster width K value and grating gap width R value (mm)
K＝R＝Y/N＝Y/2M
