Description
Technical field
The invention belongs to the image display technology field, relate to three-dimensional (3D) image Display Technique, refer more particularly to and adopt the line scanning mode to finish the liquid crystal display systems that the mutually orthogonal polarized light image of images of left and right eyes realizes that 3-dimensional image shows.
Background technology
The basic principle that 3-dimensional image shows is to transmit respectively to spectators' left eye and right eye to have small parallax and non-interfering image, by cerebral cortex the synthetic processing of two width of cloth images is produced the 3 D stereo sensation.
The method that the realization 3-dimensional image shows on LCD TV has multiple, mainly is divided into glasses type and bore hole type two classes.The bore hole type is to realize the separation of right and left eyes image by grating that is attached to the liquid crystal display screen surface or the cylindrical lens that is equivalent to grating.The shortcoming of this method is greatly to have limited the scope of watching.The 3-dimensional image display unit of glasses type is divided into shutter type and polarization image type.
Shutter type 3-dimensional image display unit, for example application number is 97108881 Chinese patent, employing at display medium (for example, projection screen, various displays etc.) go up the method for timesharing Alternation Display left-eye image and eye image, spectators put on the liquid crystal shutter glasses of the picture frequency synchronization action of Alternation Display and watch 3-D view.The defective that this method exists is liquid crystal shutter glasses complex structure, cost height, weight is big and cause wearing inconvenience.
Polarization-type 3-dimensional image display unit, for example application number is 200680033140 Chinese patent, employing is pasted one deck optical polarization film on the liquid crystal display screen surface, control polarisation of light direction separate left and eye image, and the suitable polarising glass of viewers wear is watched 3-D view.
There are technical sophistication in existing three-dimensional imaging technology and display unit more, produce and use inconvenience, the problem of cost height and three-dimensional imaging poor effect.For example: U.S. Neurok LLC application number is for providing a kind of 3-D imaging system and correlation technique that utilizes compound porjection type LCD panel in 200580039824.9 the Chinese patent application, this method adopts two-layer at least stacked liquid crystal cells, it is interior with respect at least two computed image that superpose each other on spectators' the different distance to use this compound LCD panel to be presented at panel, produces system in conjunction with suitable 3-D view and produce the continuous three-dimensional image in one or more viewing areas.But the 3-D view of this method produces the system design complexity, and adopts the technology of the computed image that spatially superposes each other, can not produce the binocular image of notable difference.
In order to obtain good 3-dimensional image display effect, must guarantee that spectators' left eye can only be observed left-eye image, right eye can only be observed eye image.If left-eye image can enter spectators' right eye, left-eye image can enter spectators' left eye, just return and produce crosstalking and confusion of right and left eyes image.Even crosstalking and chaotic just transient phenomenon of right and left eyes image also can cause 3-dimensional image to can not get correct demonstration; Can cause spectators' eyes discomfort simultaneously, more can image human body health when serious.
Jingdongfang Photoelectric Science ﹠ Technology Co., Ltd., Beijing's application number is for providing a kind of switch panel and corresponding analyzing glasses that are used for the 3-dimensional image display unit in 200810103607.7 the Chinese patent application.The exiting side of this switch panel and liquid crystal indicator polaroid portraint is fitted and is provided with, and comprises two transparency carriers, is coated with electrode on its facing surfaces respectively, and filling liquid crystal layer, and its both sides therebetween is laid with the orthogonal alignment films of orientation slots respectively.Adopt liquid crystal secondary optically-active technology to realize three-dimensional imaging.But, this patent has only considered that the whole screen of display screen is that the whole screen of left-eye image and display screen switches for the eye image two states carries out switch to described switch panel, and under the display screen normal scan, the top and the bottom of screen are respectively under the situation of left-eye image, eye image and can't allow described switch panel make response, cause this patent not have finally to solve crosstalk mutually problem with confusion of right and left eyes image.
The method that Qingdao Hisense Electric Appliance Co., Ltd's application number provides a kind of mode that adopts right and left eyes synchro switch glasses to synthesize 3-dimensional image for 200910205678.2 application, this method is respectively with the left side of display screen, the eye image frequency multiplication, as shown in Figure 9, make it to show continuously that the multiframe left-eye image switches to eye image later on, again switch to left-eye image after showing the multiframe eye image more continuously, so repeatedly endlessly, and on a left side, that frame that eye image is switched is closed the back led lighting, so left side, the frame of crosstalking of eye image can not enter beholder's eyes, and then obtains correct 3-D view.Though this method has solved the problem of right and left eyes picture crosstalk, yet, life-span of display backlight also there is certain influence because the closing repeatedly of display frame makes film flicker, brightness descend.

Embodiment
Describe in further detail below by specific embodiment and in conjunction with the accompanying drawings the present invention being done.
Figure 4 shows that the structural representation of 3-dimensional image liquid crystal display systems provided by the invention.This display system comprises LCD 100, polarization state scan control panel 400 and the polarising glass 800 of outgoing polarization picture.Described LCD 100 is existing liquid crystal indicator, as shown in Figure 1, comprises following polarizer 170, array base palte 160, following alignment films 150, liquid crystal layer 140, goes up alignment films 130, color membrane substrates 120 and upper polarizer 110.Be respectively arranged with perpendicular following polarizer 170 in polarization direction and upper polarizer 110 at the array base palte 160 and color membrane substrates 120 outsides, the inboard is coated with down alignment films 150 and last alignment films 130 respectively; Be filled with liquid crystal layer 140 between alignment films 150 and the last alignment films 130 down.Described polarization state scan control panel 400 comprises first transparency carrier 410, the transparent drive electrode 420 of first strip, first alignment films 430, liquid crystal layer 440, second alignment films 450, the transparent drive electrode 460 of first strip and second transparency carrier 470 as shown in Figure 4.Be coated with the strip like transparent electrode (420,460) identical respectively on first transparency carrier 410 and second transparency carrier, 470 facing surfaces with LCD 100 line scanning electrodes (or LCD line number); On transparent drive electrode 420,460 facing surfaces of strip, lay first alignment films 430 and second alignment films 450 respectively, and form an angle between the orientation slots on first alignment films 430 and second alignment films 450; Filling liquid crystal layer 440 between first alignment films 430 and second alignment films 450.The printing opacity polarization state of described polarising glass 800 left and right eyeglasses is mutually orthogonal.Described polarization state scan control panel 400 fits in described display 100 surfaces (light-emitting face).
In the present embodiment, liquid crystal indicator 100 is existing LCD; Two transparency carriers of polarization state scan control panel 400 are glass; The ITO (being indium tin oxide) that the transparent drive electrode of strip uses existing preparation LCD to use makes; The liquid crystal layer 440 of polarization state scan control panel can adopt TN type (being twisted nematic) liquid crystal, HTN type (being high twist orientation array type) liquid crystal or STN type (being super-twist nematic) liquid crystal to make; Only suitably angle between adjustment two orientation slots and the angle between driving voltage and the supporting polarising glass two eyeglass polarization directions get final product in practical operation.Describe as scanning panel liquid crystal layer material with TN type liquid crystal in the present embodiment.
Because liquid crystal material has dielectric anisotropy, electricity is led anisotropy and birefringence, so liquid crystal molecule arrangement under extra electric field can change, demonstrates optical activity.TN type liquid crystal cell has orthogonal first alignment films of orientation slots and second alignment films respectively in polarization scans control panel liquid crystal layer both sides, because the adherence of liquid crystal, close on the long axis of liquid crystal molecule and the parallel distribution of orientation slots direction of alignment films, intervenient liquid crystal molecule then twists 90 degree continuously and arranges.As shown in Figure 6, when not applying drive signal voltage on the first transparent drive electrode and second transparency electrode, liquid crystal molecule distortion 90 degree are arranged.Because the distortion distance of liquid crystal is greater than wavelength of visible light, the polarised light that therefore impinges perpendicularly on liquid crystal cell is in passing through the process of liquid crystal layer, and its polarization direction will be revolved along with the torsional direction of liquid crystal molecule and be turn 90 degrees.The linearly polarized photon of LCD outgoing turn 90 degrees because the optical activity of liquid crystal is revolved the polarization direction when the liquid crystal layer by polarization state scan control panel, forms and the initial vertical polarised light in polarization direction.When to the liquid crystal layer making alive, from threshold voltage V
ThThe major axis that plays liquid crystal molecule just begins to tilt to direction of an electric field, works as V=V
ThThe time, near the liquid crystal molecule electrode, the major axis of other liquid crystal molecules all rearranges along the direction that is parallel to electric field, thereby causes optical activity to disappear.Therefore when applying drive signal voltage on the first transparent drive electrode and second transparency electrode, liquid crystal molecule will be arranged by being parallel to direction of an electric field, the linearly polarized photon of LCD outgoing does not change the polarization direction by polarization state scan control panel liquid crystal layer time, and therefore seeing through the polarisation of light direction still is initial polarization direction.
Based on above principle, when the linear polarization light time from LCD outgoing certain orientation, can obtain the mutually perpendicular two kinds of linearly polarized photons in polarization direction by control to polarization state scan control panel driving signal, when viewers wear left eye and right eye eyeglass attach the polarising glass of the orthogonal polarizer in polarization direction respectively, can make left eye see the image of corresponding polarization direction, right eye is seen the image vertical with the left eye polarization direction.The drive signal that control feeds polarization state scan control panel is the periodic signal that mates with the LCD line-scanning frequency, liquid crystal display systems then provided by the invention is then with this frequency interlace refresh right and left eyes image, spectators just can see continuous and corresponding right and left eyes picture respectively from left eye and right eye, through corticocerebral processing, just can present the 3-dimensional image display effect; Simultaneously, because the linear polarization left-and right-eye images that penetrates from LCD becomes the mutually orthogonal left-and right-eye images of polarization state behind the attitude scan control panel that shakes, enter user's images of left and right eyes respectively through the mutually orthogonal polarising glass of left and right eyeglass printing opacity polarization state again, make left-eye image can not enter user's right eye, eye image can not enter user's left eye, left-and right-eye images is crosstalked mutually and chaotic problem thereby thoroughly eliminated.
In concrete the application, synchronous for the polarisation rotation that makes shown image of LCD and polarization state scan control panel, can use the periodic signal identical as drive signal with this LCD line-scanning frequency.When LCD begins to scan the N two field picture, the transparent drive electrode of strip of polarization state scan control panel under the control of drive signal with the synchronous speed of this LCD extra electric field successively, change the optical activity of the corresponding this journey scan electrode of scanning panel liquid crystal layer position, make through the polarisation of light direction to change; And the position of also not carrying out the scanning of N two field picture for LCD, what this place showed still is the N-1 two field picture, the transparent drive electrode of strip on the pairing polarization state scan control positions of panels of this position still is in no extra electric field state under the control of drive signal, see through the polarisation of light direction and do not change.This makes N two field picture and N-1 two field picture be respectively two kinds of mutually perpendicular polarised lights in polarization direction, when the supporting polarising glass of viewers wear, just makes N two field picture and N-1 two field picture see through left eye and right eye eyeglass respectively.When showing 3-D view, liquid crystal indicator will enter the image of left eye and right eye with certain broadcast frequency interval output, and for example the N-1 frame is exported left-eye image, and the N frame is just exported eye image; After N-1 frame and N two field picture saw through the left eye and right eye eyeglass of polarising glass respectively, right and left eyes had received corresponding image respectively, under corticocerebral processing, just can observe 3-D view.When this liquid crystal indicator during with higher frequency interval output left eye and eye image, the imperceptible frame of spectators interrupted just can be seen continuous right and left eyes image respectively from right and left eyes, realizes that the three-dimensional of continuous pictures is watched.
Figure 7 shows that liquid crystal display systems polarization state scan control panel 400 does not feed driving voltage, the working condition of whole 3 D image display system when promptly showing the N-1 two field picture, the polarised light of 400 pairs of LCD 100 outgoing of polarization state scan control panel carries out 90 degree rotations, light by polarising glass 800 therewith polarised light right eye polarized lenses in the same way only enter right eye; Figure 8 shows that liquid crystal display systems polarization state scan control panel 400 feeds driving voltage, the working condition of whole 3 D image display system when promptly showing the N two field picture, the polarised light of LCD 100 outgoing sees through the attitude scan control panel 400 rear polarizer directions of shaking and does not change, light by polarising glass 800 therewith polarised light left eye polarized lenses in the same way only enter left eye, realize that thus eyes observe the purpose of different images respectively.
The present invention is by being provided with the polarization direction that polarization state scan control panel changes the outgoing image at LCD outgoing front end, make the two two field picture polarization directions, front and back of the shown consecutive image of liquid crystal display systems orthogonal, be used supporting polarising glass again, make spectators' right and left eyes see different respectively but corresponding right and left eyes image, thereby realize the 3-dimensional image display effect.In actual development process, in order to adapt to various needs, can adopt HTN type liquid crystal or STN type liquid crystal to wait and replace employed TN type liquid crystal in the explanation of present embodiment technical scheme, only suitably angle between adjustment two orientation slots and the angle between driving voltage and the supporting polarising glass two eyeglass polarization directions get final product.The liquid crystal display systems scanning panel that is used for the 3-dimensional image demonstration utilizes the optical activity of liquid crystal to realize that 3-dimensional image shows, drive signal requires low, and driving circuit structure is simple, is easy to produce.When possessing outstanding three-dimensional imaging function, the scanning panel of liquid crystal display systems is simple in structure, and is lighter and thinner, and cost is lower, easy to produce and use.The supporting polarising glass that the user need wear only is two polarizers that the polarization direction forms an angle, simple in structure, with low cost and be convenient to produce, particularly other congenerous products use more lightly and comfortable on the market, can access widely and apply.
Need to prove: above embodiment is only in order to illustrating technical scheme of the present invention, and non-limiting protection scope of the present invention.All in the spirit and scope of technical solution of the present invention, the technical scheme that the foregoing description is put down in writing is made amendment, perhaps part technical characterictic wherein is equal to and replaces or improvement etc., all be included in protection scope of the present invention.
