Description
[technical field]
The invention belongs to stereo display technique, be specifically related to a kind of comprehensive stereo display technique that the light point-score is combined with time-sharing procedure.
[background technology]
Along with the development of technology such as DLP, LED, LCD, video display technology is in the stage of continuous maturation, and from the year ends 2008, flat panel display device is because of oneself limitation in aspects such as resolution, colour gamuts, and its development has run into bottleneck.In the end of the year 2009, it is the developing direction that Display Technique has indicated following first-selection---stereo display that film " A Fanda " is shown the upsurge of bringing.
Present dimension display technologies can be divided into beam split anaglyph spectacles, beam split stereo display automatically, holography and body stereo display 4 big classes altogether.And the most ripe in this 4 class stereo display technique be beam split anaglyph spectacles method.Beam split anaglyph spectacles method is to utilize the glasses wear image to be selected or adaptive, from anaglyph, sub-elect the content of the needs observation of images of left and right eyes, spectators' eyes are observed respectively after the corresponding anaglyph, vision deception effect can be in brain synthesizes the have space or depth perception image of (being third dimension) with the picture of the subsidiary parallax information of two width of cloth, thereby realizes stereo display.According to the difference of glasses operation principle, beam split anaglyph spectacles method can be subdivided into chromatism method, light point-score and time-sharing procedure three classes.
1, chromatism method
Chromatism method is the image overlap that utilizes different colours (wherein the most red and blue or red and green), uses the glasses of corresponding color to come the separating and filtering superimposed image then, reaches the depth of field.It has the very cheap advantage of cost, but visual effect also very poor, only be applied to general toy, children's book.
2, light point-score
The light point-score is based on analyzer and can selects the character of the polarization direction of transmitted light to come work, needs two image output devices in use.The light point-score is mainly used in the broadcast of movie theatre neutral body film at present.So the principle that we can play with movie theatre neutral body film is the operation principle of example explanation light point-score.
At first no matter be light point-score or time-sharing procedure, its stereoscopic images displayed all is the same, and this image all is the methods with eye-observation scenery, utilizes two video cameras of settling side by side (or camera), commissarial images of left and right eyes is shot two slightly pictures of horizontal parallax synchronously respectively.
The light point-score is in when projection, two motion picture films of corresponding images of left and right eyes is respectively charged into (being the projector 1 and 2 among Fig. 1) in the left and right projector, and installs the polarizers that two polarization directions are mutually 90 degree respectively before projection lens.Two projectors need run-in synchronism, simultaneously picture are thrown on screen, form the slur of left side picture and right picture.When spectators put on special polaroid glasses, because the polarization axle of left and right two polarized ophthalmic lenses is orthogonal, and consistent with the polarization axle before the projection lens; Cause spectators' left eye can only see that left side picture, right eye can only see right picture, by the eyes aggregation feature with left and right picture superimposition on retina, produce the visual effect of 3 D stereo by cerebral nerve.Show the stereoscopic picture plane that a width of cloth width of cloth links up, make spectators feel that scenery blows against one's face or enters the dark recess of screen, can produce the third dimension of strong " on the spot in person ".
The polarizer in the light point-score and eyeglass can be made by crystal or polarizer, and screen can be white diffusing screen or metal screen, and wherein the display effect with the metal screen is good.The light point-score is widely used, and the three-dimensional movie theatre and the stereo projection technology of the overwhelming majority all utilize the work of light point-score at present.The polarising glass of light point-score (several units to tens yuan) with low cost is one of its main advantage.But the light point-score needs the cause of two cover playback equipments, thus with high costs, its range of application is very limited.In addition, because the light point-score uses polarizing method to realize the differentiation of picture signal,, cause the brightness watched lower so there is most light to be wasted.When at present, the image brightness of using the light point-score only being shown for the identical image two dimension 1/4th to 1/5th.
3, time-sharing procedure
When three-dimensional image signal is play by output equipment (projecting apparatus, display, TV etc.), image realizes that with the form of frame sequence left and right frame alternately produces, by synchronizing signal these frame signals are transferred out, the time-division glasses of being responsible for receiving (generally using the liquid crystal light valve glasses at present) carry out synchronous alternation switch with left and right two field picture when realizing signal Synchronization.Time-sharing procedure has the 3D Vision technology of two big mainstream technology: Nvidia (tall and handsome reaching) and the DLP Link technology of TI (Texas Instrument) at present.
3.1Nvidia 3D Vision technology
The 3D Vision technology of Nvidia is the stereo display technique of the external synchronizing signal of a kind of needs.Its operation principle is illustrated in fig. 2 shown below.Display device is responsible for the broadcast of three-dimensional image signal.This kind three-dimensional image signal is made up of a series of left-eye image that have a horizontal parallax and eye image as shown in Figure 3, and these two kinds of images are alternately play, at interval not free between the adjacent image.When three-dimensional image signal was play, synchronous signal transmitter was sent synchronizing signal and is driven the switching regulator glasses work that the observer wears.When display device is play left-eye image, synchronous signal transmitter emission left eye synchronizing signal.After the switching regulator glasses received synchronizing signal, the liquid crystal lens that drives left eye was in logical light state, and the liquid crystal lens that drives right eye is in the shading state, and this moment, the observer only can see left side picture the stereo-picture from left eye; After left-eye image was play end, display device changed the broadcast eye image into, and this moment, synchronous signal transmitter was then launched the right eye synchronizing signal.After the switching regulator glasses received synchronizing signal, the liquid crystal lens that drives right eye was in logical light state, and the liquid crystal lens that drives left eye is in the shading state, and this moment, the observer only can see right side picture the stereo-picture from right eye.Because the switch speed of right and left eyes image is very fast in the stereo-picture, is shorter than the response time of human eye,, and produce the visual effect of 3 D stereo at cerebral nerve so according to the visual persistence effect of human eye, the observer will see the parallax picture that a width of cloth width of cloth links up.
3.2TI DLP Link technology
Because used external synchronizing signal, institute limits the distance of observation and the angle of observation in above-mentioned Nvidia 3D Vision technology.In order to address this problem, Ti has proposed a kind of time-division stereo display technique that does not need external synchronizing signal---DLP Link technology.
The operation principle of DLP Link technology is illustrated in fig. 4 shown below.Display device not only will be responsible for the broadcast of three-dimensional image signal also need insert gray scale image in stereo-picture.The three-dimensional image signal of DLP Link technology is made up of a series of left-eye image, eye image and gray scale images that have horizontal parallax as shown in Figure 5.Left-and right-eye images is alternately play, but inserts a GTG frame between adjacent image, and duration is about 2ms.The effect of this GTG frame is to point out the initial of left-and right-eye images and finishes.
When display device was play left-eye image, the liquid crystal lens that the switching regulator glasses drive left eye was in logical light state, and the liquid crystal lens that drives right eye is in the shading state, and this moment, the observer only can see left side picture the stereo-picture from left eye; After left-eye image is play end, display device will be play gray scale image earlier, and built-in signal sensor is sensed gray scale image in the switching regulator glasses at this moment, changes the driving voltage of two ends eyeglass, make the liquid crystal lens of left eye be in the shading state, and the liquid crystal lens of right eye is in logical light state.After gray scale image (2ms) finishes, display device output eye image, the observer only can see right side picture the stereo-picture from right eye so.After eye image finishes, play gray scale image once more, make the observer when playing left-eye image, observe the left side picture of stereo-picture to drive the operating state that glasses change the two ends eyeglass, Zhou Erfu this.Same since in the stereo-picture switch speed of right and left eyes image very fast, be shorter than response time of human eye, so according to the visual persistence effect of human eye, the observer will see the parallax picture that a width of cloth width of cloth links up, and produce the visual effect of 3 D stereo at cerebral nerve.
The present groundwork carrier of the DLP-Link technology of TI is a projecting apparatus, is applicable to the very inviolent occasions of image change such as teaching, emulation.
Time-sharing procedure is guaranteeing misalignment can not occur when glasses receive average light brightness, so be the dimension display technologies that can bring best stereo display effect.But because the price of liquid crystal light valve glasses high (as the supporting glasses price of Nvidia at the 1200 yuan/width of cloth, the glasses price of DLP-link more up to 7000 yuan about) is met difficulty when time-sharing procedure is promoted now on a large scale.
At present, light point-score and time-sharing procedure have his own strong points.Time-sharing procedure stereo display best results, and only need one to overlap playback equipment, but supporting liquid crystal light valve glasses fetch long price, and because need synchronizing signal to drive the work of liquid crystal light valve glasses, therefore only be fit to minority (majority) spectators and use, be not suitable for viewing distance and far reach the more occasion use of attendance in closer distance; The glasses of light point-score are cheap, can extend to the occasion that many spectators watch at a distance, but need two cover playback equipments, and display brightness is lower.
Therefore, in view of the shortcoming of above existing stereoscopic imaging technology, provide a kind of and be fit to closely to reach the remote occasion of more number, cost is low, the imaging stereoeffect is strong, brightness is higher digital three-dimensional display system is real in necessary.

[embodiment]
The present invention on material screens such as rear-projection, plasma, liquid crystal or CRT based on using liquid crystal as rotatory device, and cooperate the independent screen of realization that polarising glass uses and Mosaic screen (comprise the continuous stereo type, continuously the high definition solid type, look around solid type and solid type is looked around in pitching) Stereoscopic Video Presentation terminal implementation method, it utilizes light point-score and time-sharing procedure to combine to carry out plane, cambered surface and annular stereo and shows.
The present invention utilizes light-operated time-sharing procedure work, its principle is illustrated in fig. 6 shown below, and it is by showing three-dimensional image signal V (the parallax subimage V that imports observer's images of left and right eyes separately by should distinguishing of two groups of Alternation Display on special rear-projection, plasma or a LCD screen
1, V

2Switching, the polarization state of checker output image signal thereupon.Realize that key that this polarization state changes is the special construction of screen.The screen that uses among the present invention is made up of two parts: the display screen of materials such as rear-projection, plasma, liquid crystal or CRT and liquid crystal optically-active screen, wherein display screen is responsible for required three-dimensional video-frequency is shown, liquid crystal optically-active screen then is responsible for changing the polarization state of picture signal.
Playing left eye subimage V
1The time, image signal source is with signal V
1Deliver to when display screen is play and send a synchronizing signal, change the operating voltage of liquid crystal display screen to liquid crystal display screen.Optically-active principle according to liquid crystal can realize subimage V
1Light by after become the polarised light of horizontal direction, this moment signal V
1The polarising glass left side eyeglass of polarization direction and viewers wear identical but with the polarization direction quadrature of right eyeglass, spectators only can see the image of left eye.Subimage V
1Switch to right eye subimage V after finishing
2, signal source is exported the driving voltage that another synchronizing signal to liquid crystal display screen changes LCD screen, makes image V
2Become vertical polarization by the polarization state behind the liquid crystal display screen, with the polarising glass of viewers wear left side eyeglass quadrature but parallel, therefore with play signal V with the polarization direction of right eyeglass
1The time opposite, spectators only can see the image of left eye.
Because vision signal V
1And V
2Between switching frequency very high (surpass 120Hz), right and wrong same time plays so that people's vision can't be differentiated the observed image of images of left and right eyes, therefore according to visual persistence effect, two width of cloth anaglyphs (can be derived from vision signal V respectively in people's the brain
1And V
2) synthesize image with stereoscopic vision.
Though technology such as rear-projection, plasma, liquid crystal or CRT screen can be suitable for the equipment that shows as vision signal in the present invention.But plasma, liquid crystal and CRT screen are made up of the array of pixel, have fixing orientation and certain line-spacing, if therefore their fronts add realize that electricity causes the liquid crystal display screen of optically-active in, because equally also having certain direction, arranges liquid crystal display screen, so be easy to generate Moire fringe, cause the sense of discomfort of watching.And the operation principle of rear-projection technology does not have the characteristic that forms pixel separation, therefore can not produce Moire fringe, recommends the means of using the rear-projection technology to show as vision signal.
Liquid crystal display screen among the present invention is the core Primary Component, mainly is that the synchronizing signal that plays according to input changes self optically-active characteristic effect.Have only and utilize liquid crystal display screen image could be arranged the direction transformation of arranging towards the light-operated time-division from the simple time-division.In actual conditions, except liquid crystal has the controlled function in polarization direction, also have other materials to have this function, for example: electrooptic crystal (potassium dihydrogen phosphate, ammonium dihydrogen phosphate, lithium niobate, lithium tantalate etc.), magneto-optical crystal (as quartz) etc., but from the angle of optimizing, liquid crystal can be made large-area screen, and advantage such as half-wave voltage is low, is more suitable for the scheme among the present invention.
The liquid crystal material that uses among the present invention is nematic phase (or claiming nematic liquid crystal), and nematic phase does not have the position order, but has the direction order, and the molecular long axis direction is in common direction of average sensing.Nematic liquid crystal has various modes in application, wherein a kind of is twisted nematic (Twisted Nematic-LCD) pattern.Charge into liquid crystal between two blocks of glass (pi/2 staggers mutually) with orientation slots, liquid crystal is because the effect of power forms following arrangement: the liquid crystal layer major axis of pressing close to glass is arranged along orientation slots, and the major axis of middle liquid crystal layer is orientated transition gradually.Each layer liquid crystal molecule can be regarded as the birefringent waveplates wafer that a layer thickness is the liquid crystal molecule dimension, its optical axis is parallel with the average orientation of long axis of liquid crystal molecule in this liquid crystal layer.The optical axis direction of equivalence quarter wave plate 14 successively rotates.
After applying a certain size alternating voltage for the liquid crystal molecule by electrode, Fredericks will take place liquid crystal changes, and Liquid Crystal Molecules Alignment is moved, thereby is in excitation state.When applied voltage during greater than critical voltage Vth, long axis of liquid crystal molecule will begin to be inclined to direction of an electric field, and when applied voltage is 2 times of Vth left and right sides, except near the molecule the electrode surface, the major axis of nearly all molecule all will be parallel to electric field and arrange the change of polarized direction pi/2 again.So, can realize the change of light polarization direction by the control of voltage.
Because liquid crystal material correspondingly has different threshold voltage vt h for different colours, polarization direction after promptly wanting to allow the light of Red Green Blue of rear-projection chip reflection by liquid crystal all changes pi/2 accurately, then needs respectively the liquid crystal operating voltage that colour wheel was under " opening " time of three kinds of colors of red, green, blue is finely tuned.The refresh rate of the inspection image among the present invention is at 120Hz, and therefore the demonstration time of every two field picture is slightly more than 8ms.Consider that DLP adopts the work of three primary colors time division way, therefore corresponding to projection time of various primary colors in every frame less than 3ms, so the present invention requires the response time of liquid crystal can not be slower than the projection time of each primary colors in single frames.At present, adopt the civilian display fastest response speed of TN panel can reach 2ms, as seen can satisfy requirement of the present invention.
The above is preferred embodiment of the present invention only, and protection scope of the present invention is not limited thereto, and anyly all belongs within the protection range of the present invention based on the equivalent transformation on the technical solution of the present invention.
