Description

The two and three dimensions display
Technical field
[0001] the present invention relates to universal display equipment and display packing and device, more specifically, relate to many vision image display device and method.It specifically relates to three-dimensional (3-D) image display that uses polarised light, and more specifically, relates to a kind of two dimension (2-D) and three-dimensional (3-D) unified display packing and equipment.
Background technology
[0002] common, it is a process that picture is resolved into a plurality of junior units and shows respectively on indicator screen that electronic image shows.Enough hour of unit after being decomposed, complete thereby these can't be formed on device screen by the mankind's eyes separate in the unit that separates on the display screen, smooth picture.Picture junior unit after these decompose is called pixel, shows on the display screen that the absolute construction of a pixel is called a pixel cell, is called for short the unit.
[0003] pixel can be monochromatic or different colors is arranged.Make up a coloured pixel, a pixel will further be resolved into one group of former colour content.Primary colors is one group of specific color, can produce any color in the color space by the former colour contents of mixing different amounts in theory.There is the different primary colors of many groups.Such as redness, green and blueness are one group of primary colors commonly used.
[0004] behind selected one group of primary colors, a pixel cell further is divided into a plurality of subelements, is called color cell, and each subelement is represented a primary colors in the selected primary color set.By controlling the amount of a pixel cell at the light of each color cell, a pixel cell can have many different colors and brightness degree.
[0005] human two real worlds of image viewing that obtain by two eyes.Human brain is resolved this two width of cloth image, therefrom produces space length and forms the 3-D vision.This observation process of 3-D display simulates.Beholder's different eyes see that on screen two width of cloth resemble at the observed slightly different image of real world.The image of being seen by right and left eyes is called as left image and right image respectively, and it is right that they are also referred to as stereo-picture.
[0006] liquid crystal (LC) is a kind of material with following denominator: its molecule is arranged with the state of confusion under nature and is had a tendency by its long axis direction parallel arranged; When its contact had stria surperficial, molecule was pressed stria direction proper alignment; When electric field action was on it, molecule was voluntarily from new arrangement and make the direction of its long axis direction along electric field.
[0007] when light passes LC, the direction of vibration of light is followed the long axis direction of LC molecule.When LC is sandwiched between two plate planes and the plane facing surfaces has stria on stria and two planes when becoming a special angle,, light divide its direction of vibration of the period of the day from 11 p.m. to 1 a.m to change identical angle when passing such LC.When directive effect that electric field sees through with light was on it, the direction of vibration of light remained unchanged.
[0008] this LC characteristic is used to make up common liquid crystals display (LCD).Fig. 1 is the functional structure sectional drawing of the screen of existing LCD.First polarizing coating 110 will convert polarised light to from the light of backlight 101 and its single vibration direction is parallel with the polarization direction of first polarizing coating 110.Guide layer quilt round brush subtly is a certain degree on the surface of two boards and their direction.Thereby the polarization direction of the polarization direction of second polarizing coating 111 and first polarizing coating 110 is a certain degree makes the polarised light that passes LC119 change its direction of vibration to the direction of the polarization direction quadrature of second polarizing coating 111 and stopped fully.The value of the angular separation between this two-layer polarizing coating is determined by employed LC material.
[0009] for instance, for twisted nematic (TN) liquid crystal material, when the round brush direction of guide layer 117 and 118 was orthogonal thereto, this angle was 90 degree.The light intensity that thereby electrode layer 115 and 116 provides the electric field controls that drives LC molecular distortion degree to make to be seen through changes between all-pass and full resistance.With colour filter 114, this variation provides different color and brightness on each color cell, thereby different color and brightness is provided on each pixel cell, thereby forms a complete image on screen.Thereby LCD plate 102 is a kind of by the structure that forms image when light passes it control, that light switch function is provided of the electronic signal on each color cell or the pixel cell.
[0010] Fig. 2 is the function profile of a double polarizing light filter (DPF), and it is disclosed interim U.S. Patent application 60/558,898 and U.S. Patent application 11/092,889, and the two is all here introduced by reference.It comprises that first substrate 123 and second substrate 122 are spaced from each other, selectable colour filter 124, signal controlling electrode layer 125, the first guide layers 128, liquid crystal layer 129, the second guide layers 127 and can select common electrode layer 126 by stratification between two-layer substrate.Constituting matrix circuit, transparent pixels electrode and the switch of signal controlling electrode layer such as TFT or fellow's detailed structure does not show in the drawings.For pad and other feature capability circuit layer of the consistency thickness that keeps LC layer 129 also shows in the drawings.The double polarizing light filter is an a kind of structure that provides light to reverse function by the control of the electronic signal on each color cell, is called as the unit in the color cell patent application in the past.
Summary of the invention
[0011] display device of being invented can show 2-D and 3-D image simultaneously.When putting on polarised light glasses, the beholder forms the 3-D vision.Whether the 2-D image is all unaffected to put on polarised light glasses.This display device also can show the 2-D image that two width of cloth are different simultaneously, and a width of cloth can only another width of cloth can only be viewed by polarised light glasses by bore hole is viewed.
[0012] this display uses 2-D image of the simple demonstration of one tunnel common data stream as common display equipment.Represented the data flow of the image that will on screen, show have and be used for the same form of common 2-D data presented stream.
[0013] will show 2-D and 3-D image or a plurality of 2-D image of 3-D image or mixing on screen, display uses the input of two paths of data stream.When display by hardware, software, or software and hardware, when the internal data signal conversion was provided, this two paths of data input can be common 2-D data format, and represented the stereo-picture that forms three-dimensional 3-D vision to or represented several 2-D images.When display does not provide the internal data signal conversion, this two paths of data stream input also can be a kind of special data format, two paths of data itself all can not intactly be represented 2-D or the 3D rendering on the screen, but two paths of data input combines and represents 2-D and 3-D image on the screen.External hardware module that the special data flow of this two-way can be separated by the 2-D image data stream and the use of two-way common format or software module or software and hardware mixing module produce.The data flow that is input to display can be parallel or serial.Under serial data mode, two paths of data is mixed to be transmitted and stores.Display separates them in inside or externally they is separated by separate processor.Under the parallel data pattern, this two paths of data is input to display simultaneously.When two paths of data stream is input to display when asynchronous, they in display interior by temporary and keep in and synchronous synchronously or by an outside display handling process.
[0014] display comprises two critical pieces.Parts are referred to as main screen, can show common 2-D image independently.Another parts are dual-polarization filter DPF, are also referred to as auxilliary screen, can show stereo-picture auxiliary data and second 2-D view data.Last each unit that can independently control of DPF is corresponding one by one with each color cell on the main screen and align.Rendered image data is sightless to bore hole and can only can sees by special polarised light glasses on DPF.The view data of playing up on main screen can both be seen by bore hole and polarised light glasses.
[0015] when only showing the 2-D image, independent common 2-D data flow is played up on main screen, and display is used as any regular display.When showing 3-D or a plurality of 2-D image, the common 2-D data flow of two-way is converted into the special data flow of two-way, and one the tunnel is called as primary traffic, and another road is called as auxilliary data flow, and is rendered into respectively on main screen and the DPF.The common 2-D data flow of this two-way can represent three-dimensional 3-D image to or represent two different 2-D images.Because the 2-D image is rendered on the main screen at any time, so do not need the display mode switch to come to showing the 2-D image, the 3-D image, 2-D and 3-D vision-mix, or several 2-D images distinguish, and 3-D image and second 2-D image of producing by DPF have only by polarised light glasses and can be seen.
[0016] will obtain 3-D vision or see second 2-D image, the beholder need put on polarised light glasses.The polarization axis direction that is used to obtain its left and right sides eyeglass of polarised light glasses of 3-D vision is a quadrature.It is parallel being used to watch the polarization axis direction of its left and right sides eyeglass of polarised light glasses of second 2-D image.
[0017] main screen provides the whole luminous energy that arrive beholder's eyes.It can be polarised light form or normal optical form.The light that enters DPF can be polarization.Thereby DPF will reverse a specific angle through its polarisation of light direction and make to have only part light to be filtered through each eyeglass.When using the 3-D polarising glass, DPF provides cutting apart of luminous energy to reversing to left and right sides eyes of polarization direction.When using the 2-D polarising glass, DPF is to the filtration that luminous energy is provided for two eyes of reversing of polarization direction.DPF does not exert an influence to the luminous energy that reverses arriving bore hole of polarization direction.
[0018] when showing the vision-mix of 3-D image or 2-D and 3-D, main screen is controllably in each pixel cell and further left image and the needed total light energy of right image of providing on each color cell.Main screen and corresponding controlling mechanism thereof also can be called as the luminous flux controller.DPF is controllably at each pixel cell and further cut apart total light energy for left image and right image between two polarized lenses on each color cell.By the windup-degree of control when polarised light polarization direction during by each the DPF unit that can independently control, the 3-D polarising glass, the polarizing axis of two eyeglass meets at right angles, and in non-interfering mode light is separated.If promptly a part of light sees through a polarized lenses fully, this part light is then simultaneously stopped fully that by another polarized lenses vice versa.
[0019] be controlled in each pixel cell and when further the luminous energy on each color cell is divided two eyeglasses equally as DPF, two eyes behind the eyeglass are seen identical color and brightness on identical pixel cell, and then, two eyes are seen the identical image that is made of these pixel cells, thereby form the 2-D vision.When DPF is controlled in not each pixel cell and when further the luminous energy on each color cell is divided two eyeglasses equally, two eyes behind the eyeglass are seen different colors and brightness on identical pixel cell, and then, two eyes are seen the different images that is made of these pixel cells, the image of seeing when left eye and right eye be stereo-picture to the time then form the 3-D vision.Do not wear the 3-D polarising glass, because no matter what direction polarised light is, two bore holes are all seen the luminous energy of equivalent on same pixel point, the 2-D image is clear that, and the 3-D image blurs.
[0020] will show that pure 2-D image do not wear polarising glass display is used when common 2-D display, DPF can be in non operating state.Be that DPF go up to load any control signal or increase control signal not fully.This also means only needs the input of circuit-switched data stream.
[0021] in the time of will showing two 2-D images simultaneously on screen, master image is watched by bore hole and second image watched by the 2-D polarising glass, and two eyeglasses of 2-D polarising glass have identical polarization axis direction.Main screen is controlled to and shows master image and DPF is used to the luminous energy on each color cell that forms master image on the main screen is adjusted and formed second image.See through the degree of reversing of polarization direction of polarised light of each unit of DPF by control, we can adjust the luminous energy that sees through the polarising glass that is used to watch second image, and the polarization axle of two eyeglasses of this polarising glass is parallel.Thisly seeing through polarized lenses on the identical image unit on the screen and do not seeing through different color and the brightness of formation under the situation of polarized lenses through adjusted luminous energy on each color cell.Further, these see through polarized lenses and descried different colours second image different with master image with brightness formation.Although the quality of second image is played up the influence of the master image on main screen, can cause this pixel cell not have enough luminous energy to offer DPF this pixel cell is adjusted forming the color of second image at this pixel cell such as master image is very dark on certain pixel cell, luminous energy that this situation can be by utilizing its neighboring pixel unit and colour harmony theory modulate with the try one's best mode of approaching color of the needed color of second image and obtain to a certain degree improvement.Form high-quality second image, the brightness of common master image is than the brightness height of second image, and the color purity of second image is than the color purity height of master image.
[0022] the multistage light-operated technology of this use new method of carrying out image configuration can be applied on the existing different Display Technique with equipment, as LCD, and PDP, LED, CRT, and OLED, or on their similar technique.The display of these types can be used as the main screen of display device of the present invention.If main screen is sent polarised light, DPF can be fitted on the main screen, and each pixel alignment.Shielded when suitable main screen data flow correspondingly is applied to main screen and assists with auxilliary screen data flow, the beholder can see 2-D image and 3-D image or a plurality of 2-D image simultaneously on same screen.If main screen is not sent polarised light, the auxilliary screen of can behind applying a slice polarizing coating on the main screen, fitting again.Main screen data flow in this case and auxilliary screen data flow do not change.
[0023] will form the 3-D vision, beholder's right and left eyes need be seen slightly different images on screen.This means that each pixel cell on the screen must show simultaneously that thereby the picture point of left image and right image makes the 3-D image of demonstration have the display precision or the picture quality of the supported maximum of physical location precision of display screen.
[0024] Ren Lei eyes are by color and picture point of brightness identification of picture point.The light intensity of color by one group of given primary colors makes up and embodies.The stack of the light intensity of the various combination of the light intensity of each primary colors different color of definition and each primary colors has defined brightness.Make up in any colour planning of certain luminance is that light intensity to the one-tenth color separation of a certain group of selected primary colors is controlled.Make up three-dimensional 3-D image and be actually the amount that control independently arrives the light of left eye and right eye, or intensity.
[0025] use the two-stage optical controller can realize this target.The control of first order controller arrives total light quantity of two eyes.Second level controller is controlled the allocation proportion of light between left eye and right eye of this amount.
[0026] the control rate Rm of first order controller is between zero (0) and one (1).When Rm was 0, first order controller cut out fully, did not have light to export from first order controller fully; When Rm was 1, first order controller was opened to greatest extent, so the light quantity of first order controller output reaches maximum M.
[0027] the control rate Ra of second level controller is also between zero (0) and one (1).When Ra is 0, second level controller from the photoconduction of first order controller 100% to the photoconduction of first eyes and 0% to second eye; When Ra is 1, second level controller from the photoconduction of first order controller 0% to the photoconduction of first eyes and 100% to second eye.
[0028] supposes that E1 is the unit light quantity of a primitive color light composition of a pixel of the image that should see of first eyes, E2 is another image that another eyes should be seen, in same position, the unit light quantity of a same primary color light component of a pixel, we have following relational equation:
Rm=(E1+E2)/2 and
Ra=E2/(E1+E2)
Wherein the span interval of the good E2 of E1 all is between zero (0) and one (1).
[0029] corresponding, relational equation:
Rm=(E1+E2)/2 and
Ra=E1/(E1+E2)
Represented following control sight: when Ra is 0, second level controller from the photoconduction of first order controller 100% to the photoconduction of second eye and 0% to first eyes; When Ra is 1, second level controller from the photoconduction of first order controller 0% to the photoconduction of second eye and 100% to first eyes.
[0030] for digitized image, image is expressed by pixel and each pixel is expressed by the color numerical value of one group of selected primary colors.The scope of color numerical value is between zero (0) and one (1).Such as, selected red (r), green (g), blue (b) is as primary color set, first image A 1 position P (x, some pixel p1 y) can be expressed as [r1, g1, b1], (x, pixel p2 y) can be expressed as [r2, g2, b2] to second image A 2 at same position P simultaneously.Here x and y are the coordinate figures under a given coordinate system, r1, and g1, b1, r2, g2, b2 are the respective color values of respective pixel point p1 and the p2 of composing images A1 and A2.Make different eyes independence and see p1 and p2 respectively, first order controller represent images position P (x, the photocontrol rate Rm of pixel cell y) and can use the color value of p1 and p2 to calculate at the photocontrol rate Ra of the pixel cell of second level controller performance same position P, and same calculating can be applied on each primary color value of selected primary color set independently, its corresponding value is [(r1+r2)/2, (g1+g2)/2, ] and [r2/ (r1+r2) (b1+b2)/2, g2/ (g1+g2), b2/ (b1+b2)].Under this control, these pixels of being seen respectively by different eyes constitute separate and also image independently.When these two images are stereo-pictures to the time, they form three-dimensional 3-D vision to the beholder.
[0031] because second level photocontrol distributes whole light quantities between two eyes, when to the identical image of two eyes structure, the light quantity that arrives each eye arrives the light quantity of each eye during in fact than this special photocontrol not and lacks.Allow two eyes all receive the image A 1 of demonstration in normal way or the identical light quantity of A2 under the situation of this special light control method and equipment, the maximum amount that penetrates from first order optical controller will be adjusted to 2M.Yet because this new light-operated method and apparatus is to be used for that design of graphics is as A1 and A2 respectively to different eyes, the maximum amount that penetrates from first order optical controller can remain in identical M.
[0032] control data of the first order and second level control can make up by the first and second original image data streams.If the pixel data D1 of the first original data flow is the serial numerical value of R, G, B, the pixel data D2 of the second simultaneously original data flow is the serial numerical value of R, G, B, and new control data stream is built into original data flow same form.The control data of the new control data stream that makes up is corresponding to the C1 value of a serial of R, G, B value in the original data stream and the C2 value of a serial.Here C1=(D1+D2)/2 C2=T*D2/ (D1+D2) simultaneously, this wherein T be the maximum of raw image data.For digitized data, it is by the byte length decision of D1 and D2.C2 also can be constructed as T*D1/ (D1+D2) and controls the second level control light is distributed in another way.These control datas C1 and C2 constitute control data stream when their data flow data D1 by first and second images and D2 are fabricated out.These two control data flow data C1 and C2 are applied to respectively as the main screen of first order photocontrol with as on the DPF of second level photocontrol, are rendered on main screen or the DPF as image data stream.Such as, if a rgb value D1 of first data flow is 10, be shown 00001010 with binary form, the rgb value D2 of second data flow of its correspondence is 34, be shown 00100010 with binary form, the value of data C1 on the light-operated data flow of the first order that is applied to main screen of neotectonics is that the value of the data C2 on the light-operated data flow in the second level that is applied to DPF of (10+34)/2=22 and neotectonics is 255*10/ (10+34)=57.955 so, or about 58,255 is maximums of 8 bit binary number here.
[0033] these control data values, C1 or C2 can precompute and exist in the block of memory.Each unit of this block of memory can carry out unique addressing by view data D1 and D2.Make up the address of this block of memory, D1 and D2 can be linked into a value, and D1 is a high order bit and D2 is a low-order bit, or conversely.Deposit the value of C1 or C2 by the mnemon of " D1D2 " or " D2D1 " addressing or sensing.The value of C1 and C2 also can comprise other correction value part except comprising the numerical part that constructs by D1 and D2, thereby makes them light-operatedly carry out more accurate control and drive first and second grades.Because the torque response and the added voltage of liquid crystal are not to be perfect linear relationship, linear correction value B, it is the function of a C value, can be incorporated among the basic controlling value C.Both in conjunction with after final controlling value C can be stored in the mnemon by D1 and D2 addressing.
[0034] such as, the C1 value 22 that is calculated by D1 value 10 and D2 value 34 can be existed on the mnemon of first block of memory, this element address or can be configured to " 0000101000100010 " from the skew of address block first address, the binary value that its high 8 bits are D1, low 8 bits are binary values of D2, the 2594th unit of this value sensing order.The C2 value 58 that is calculated by identical D1 and D2 value can be existed on the mnemon of second block of memory, and this element address or be 2594 equally from the deviant of this address block first address.If the linear correction value B of corresponding C1 value 22 is-1, what then Unit the 2594th of first block of memory was deposited is their combined value 21, i.e. 22+ (1).
[0035] for accurate requirement, said here mnemon can be stored the data of any selected bit length.Numerical value B also can leave in the different block of memory and carry out addressing in the same way, so numerical value B can be obtained as uncorrected control numerical value.The numerical value B that takes out from block of memory can be added on the uncorrected control numerical value, and this uncorrected control numerical value can come from block of memory and also can obtain by dynamic calculation.Can exist such as B value (1) on the 22nd unit of the 3rd block of memory.For given view data 10 and 34, the value 22 that prestores is positioned on the 2594th unit of first block of memory, and the value that prestores simultaneously (1) is positioned on the 22nd unit of the 3rd block of memory, and final control data value be 22 and (1) and.
[0036] structure of control data stream can pass through software or hardware or the combination of the two.When by software building, original view data can be kept in internal memory before being output to display device, after handling, writes back to internal memory again.Control data is sent to display device and control data C1 as general image data stream and is played up on the main screen and control data C2 is played up on DPF.When by constructed in hardware, this hardware can be an external equipment or an inside chip and a combination of circuits as a display device part, and two-way raw image data stream can be directly inputted in the hardware and be rendered into control data on main screen and the DPF by constructed in hardware.
[0037] no matter be control data stream or image data stream, the data flow that is input to display device can be by different interface concurrent inputs.They should be synchronous.Otherwise they should be kept in when software or hardware handles by temporary and be undertaken synchronously.Data flow also can be passed through with their mixing or by different frequencies or in parallel input on same interface on the same frequency of different time sections.When they mixed on different frequencies, the gap of these two frequencies can be preestablished.The display device that can show dual-polarization 3-D image can receive this two input signals simultaneously.When frequency of locking, another respective frequencies can be by predetermined frequency distance locking.Display device that can only show common 2-D image will lock these two frequencies respectively and show these two data flow respectively and do not influence each other.When they mix by the same frequency on the different time sections, the data flow of mixing processed or be rendered into different screen before separated and temporary to different memory buffer areas.When data flow was mixed by different time sections, they were undertaken realizing synchronously that by temporary dual-polarization shows.
[0038] any common display equipment can be used as first order controller.A double polarizing light filter of describing in interim U.S. Patent Application Serial No. 60/558,898 can be used as second level controller.Yet the realization of first order controller and second level controller is not limited to regular display and double polarizing light filter.
[0039] the present invention has disclosed a kind of new method and the device that makes up 2-D and three-dimensional 3-D image on display screen.The very high and rich color of picture quality.Shown image can reach the full accuracy that the display screen physical precision can be supported.Production procedure is simple and economical.It support naturally the available data form of the image that is useful on and video.
[0040] display packing of being invented and equipment can provide the 3-D image and the 2-D image of full precision simultaneously when the beholder wears the 3-D polarised light glasses.Whether be presented at the 2-D image on the screen all is identical no matter the beholder wears polarised light glasses.
[0041] new method of this structure 2-D and 3-D image and equipment can be applied to any self luminous display device, send out natural daylight or polarised light no matter be.
[0042] display packing of being invented and equipment also can provide the different 2-D image of two width of cloth of full precision simultaneously.One width of cloth only can be seen by bore hole and another width of cloth only can be seen by the 2-D polarised light glasses different with the 3-D polarised light glasses.
[0043] display packing of being invented also provides a kind of new method of the 3-D of structure projecting apparatus.For projecting apparatus based on LCD, between LCD display panel and optical focusing system, insert a DPF, and use disclosed control data signal stream among the present invention, just make up a projecting apparatus that on projection screen, throws 2-D and 3D rendering.The 3-D image that reflects from screen passes through the in sight and formation 3-D vision of polarised light glasses.Corresponding with each control unit on the dual-polarization filter and align when the color cell on each LCD display panel, the emergent light that application controls signal C1 and C2 produce is the mixing of two orthogonal polarised lights in polarization direction.Different images can be expressed by the light with different polarization direction.For projecting apparatus based on DLP, between DLP chip and optical focusing system, insert a DPF, and stick a slice polarizing coating in one side towards the DPF of DLP chip, and use disclosed control data signal stream among the present invention, also can make up the projecting apparatus of a projection 2-D and 3D rendering.The light that is reflected by micro-reflector becomes the mixing that polarised light also further becomes two orthogonal polarised lights in polarization direction when seeing through the dual-polarization filter.

Detailed description of the present invention
[0054] Fig. 3 is based on the functional structure cross-section view of the embodiment 100 of LCD display.This device comprises backlight 101, LCD display panel 102, dual-polarization filter 103 and 3-D polarised light glasses 104.The pixel cell of LCD display panel 102 and dual-polarization filter 103 and color cell thereof are pressed row and column alignment and corresponding one by one.Pixel cell 202 comprises at least one color cell 203.Color filter plate 124 can be omitted.If but color filter plate 114 and 124 uses same primary color set and color cell size and the distribution pattern of 114 and 124 uses simultaneously.Corresponding signal controlling electrode layer 115 has identical color cell size and distribution pattern equally with 125.In other words, no matter what color cell are formed a pixel, also no matter these color cell are how to arrange to constitute a pixel, each the corresponding color unit on 102 and 103 is pressed row and column by its identical color and is alignd.
[0055] visual control electrode layer 115 and 125 uses transparency electrode, and matrix circuit and TFT switch and other control circuit (not shown) provide each color cell control. Bulletin electrode layer 116 and 126 can be omitted when image control electrode layer 115 or 125 uses the circuit of certain particular type. Color filter plate 114 or 124 can be placed on the different positions, can lean against on any one substrate such as it.If two color filter plates 114 and 124 all are omitted, display just becomes black and white display.
Magnitude of voltage on the LC molecular layer 119 that is arranged so that any color cell that is added in LCD display panel 102 of [0056] the first polarized film polarization axis direction 151 and the second polarized film polarization axis direction 152 is when V0 changes to V1, from this color cell transmit from the amount of the light of backlight 101 from maximum, promptly see through fully, to minimum value, i.e. blocking-up fully, and vice versa.
[0057] the first eyeglass polarization axis direction 153 of 3-D glasses and the second eyeglass polarization axis direction 154 is arranged so that any color cell to dual-polarization filter 103, magnitude of voltage on being added in LC molecular layer 129 is when U0 changes to U1, and the amount that penetrates and see through the light of first eyeglass from this color cell changes to minimum from maximum.The amount of light that penetrates and see through second eyeglass from this color cell is accordingly from the minimum change to the maximum simultaneously, and vice versa.At any one given time point, the maximum amount that sees through two eyeglasses is the whole light quantities that penetrate from LCD display panel 102 to any one color cell; Minimum amount of light is zero, and promptly polarized lenses is blocked the light that penetrates from LCD display panel 102 fully.Any moment always replenish mutually from the amount of the light that sees through first eyeglass and second eyeglass of any color cell of display and they and equate with the amount of the light that penetrates from LCD display panel 102.
[0058] thus, be added to voltage on the LC layer 119 by control, we can at any time control the amount of the light that each color cell of any pixel cell penetrates on the LCD display panel 102.Be added to voltage on the LC layer 129 by control, we can distribute the light of any given time from any color cell of LCD display panel 102 between two polarized lenses, thereby make the part of this light see through the part of an eyeglass and remainder through another eyeglass.This makes beholder's left eye watch different light intensity with right eye on the same color unit of synchronization at display screen.Left eye can be seen different colors and brightness with right eye on the same pixel cell of synchronization at display screen thus.Consequently left eye is seen different images simultaneously independently with right eye on same screen.
[0059] when on screen, showing the 2-D image, each color cell of LCD display panel 102 is controlled in color and the brightness with the pixel cell that forms this color cell place of the state that makes the suitable amount of the light transmission that comes from backlight, thereby forms the 2-D image on LCD display panel 102.Accordingly, each color cell of dual-polarization filter 103 is controlled in the state that the light that distributes each corresponding color cell to penetrate sees through two eyeglasses of polarising glass 104 equally.Thereby when the beholder wore 3-D polarising glass 104, two eyes of beholder were seen the light of same amount on same color cell, and then each pixel cell on screen sees same color, thereby formed the 2-D vision.When the beholder does not wear 3-D polarised light glasses 104, because the polarisation of light direction that is changed by dual-polarization filter 103 does not make a difference to bore hole, two eyes are always seen whole light quantities that the same color cell from the LCD display panel 102 penetrates, and then on same screen pixels unit, see same color and brightness, thereby form the 2-D image in the same mode of common display screen.
[0060] when showing the image that 3-D image or 3-D and 2-D mix on screen, the demonstration of 2-D image-region is with above-described identical.For the zone of 3-D image, each color cell on the LCD display panel 102 is controlled in the state of the total amount of the color institute light requirement that sees through left image of structure and right image corresponding pixel points.The total amount that the color cell of each alignment on the dual-polarization filter 103 is controlled in the light that each the corresponding color unit from LCD display panel 102 is penetrated is assigned to the state of left avertence galvanometer sheet and right avertence galvanometer sheet, thereby can be in sight on the same pixel unit of screen by the different color of different eyeglasses.These different colours of seeing through different eyeglass form different images to left eye and right eye.When the image of independently being seen by two eyes be stereo-picture to the time, just form three-dimensional 3-D vision.When the beholder does not wear glasses, the 3-D image section blurs, because the light that the color cell on the LCD display panel 102 penetrates can not normally form image at the 3-D image-region.But the 2-D image-region is unaffected.
[0061] Fig. 4 is the functional structure cross-section view that the present invention is based on an embodiment 200 of any display device of launching normal optical.This system comprises common 2-D display 201, polarizing coating 211, dual-polarization filter 103 and polarised light glasses 104.Common 2-D display 201 has a display screen 210, and its pixel cell 202 has a plurality of subelements that are called as color cell 203 with certain arranged in patterns with certain arranged in patterns and each pixel cell.Each color cell 203 representative is used for the primary colors that the pixel cell color makes up a selected primary color set.Color cell on these screens 210 can be formed suitable color and brightness for the pixel cell under them by independent control ground, and and then forms image on screen 210.Polarizing coating 211 converts the light that display screen 210 penetrates to polarization direction 252 polarised light.Dual-polarization filter 103 has the identical layer structure of using with embodiment 100 of dual-polarization filter.Pixel on the dual-polarization filter 103, and then the pixel on color cell and the display screen 210 or color cell have identical size and identical shape and with identical arranged in patterns.These pixel cells, and the color cell in each pixel cell is all corresponding one by one and press row and column and align.
[0062] polarization axle 154 of the polarization axle 153 of first eyeglass of 3-D polarising glass 104 and second eyeglass is provided with by this way, promptly to any color cell of dual-polarization filter 103, magnitude of voltage on being added to LC material layer 129 is when U0 changes to U1, the amount that penetrates and see through the light of first eyeglass changes to minimum from maximum, the amount of light that penetrates and see through second eyeglass simultaneously is accordingly from the minimum change to the maximum, or vice versa.For any color cell point at any given time, the maximum of amount that sees through the light of eyeglass is the light summation that penetrates from display screen 210 and polarizing coating 252; The minimum value of the amount of light is zero, and promptly polarized lenses will be blocked fully from the light of screen 210 and polarizing coating 252.At any time, from any one color cell on the display, the amount of light of first eyeglass and second eyeglass of seeing through always complementary and they and the amount that is equal to the light that penetrates from screen 210 and polarizing coating 252.
[0063] when showing the 2-D image, regular display 201 rendering image while dual-polarization filter 103 under the general control pattern is controlled in the state that the light that each color cell is penetrated is divided two eyeglasses of polarised light glasses 104 equally.Thereby no matter whether wear polarised light glasses, the same color cell of two eyes on screen seen identical light quantity and then seen identical color and brightness in the same pixel unit of screen.
[0064] when showing the 3-D image, display components 201 is controlled to the ejaculation value be left image and right image each color cell institute light requirement and light quantity.Dual-polarization filter 103 is controlled to the light of each color cell ejaculation that distributes on the display components screen 210 to left eyeglass and right eyeglass, thereby makes the light of the appropriate amount that penetrates on each color cell in sight by left eyeglass and right eyeglass.The right and left eyes that sees through 3-D polarised light glasses 104 beholders is seen different colours and brightness on the pixel cell of display components screen 210.The different colours that these are seen by polarized lenses 153 and 154 and the image point of brightness form different images to right and left eyes, and they are right left image of stereo-picture and right image, thereby form three-dimensional 3-D vision for the beholder.
[0065] if display device self polarized light-emitting, the polarizing coating between display screen 201 and the dual-polarization filter 103 can be omitted.Fig. 5 is based on the functional structure cross-section view of an embodiment 300 of any display device of polarized light-emitting.302 and 303 is respectively the pixel cell and the color cell of display, and they are equal to 202 and 203 of Fig. 4 respectively.The color cell of the pixel cell of screen 210 and dual-polarization filter 103 and it has same same size and shape and aligns by row and column.The direction of polarized light that penetrates from screen 310 is 352.Polarizing coating 211 among Fig. 4 will convert the polarised light with polarization direction 252 through its normal optical to, with the equivalence on function of the polarised light with polarization direction 352 among Fig. 5.Polarised light directly penetrates from screen 310.Therefore be applied on the dual-polarization filter 103 among Fig. 5 control mode be applied to Fig. 4 in dual-polarization filter 103 on control mode identical.The data-signal of delivering to display components 301 shows also all identical with the data-signal of delivering to display components 201 to 2-D and 3-D.
[0066] Fig. 6 is the light control method showed and the another kind of embodiment of equipment.Display device 400 shows an image and shows different images to the spectators that do not wear polarising glass to the spectators that wear the 2-D polarised light glasses.This system is included in Fig. 3, Fig. 4, or disclosed 3-D display embodiment and 2-D polarising glass 204 among Fig. 5.
[0067] difference is arranged between 3-D polarising glass and the 2-D polarising glass.The polarization axle of two eyeglasses of 3-D polarising glass 104 is mutually orthogonal.2-D polarising glass 204 has two polarized lenses of same polarization axis direction 253.For given polarized film polarization axis 252 or given direction of polarized light 252 from screen 210 ejaculations, the direction that polarized lenses polarization axle 253 is set up makes to any color cell on the dual-polarization filter 103, when the value of the control voltage that is added to LC material layer 129 when U0 changes to U1, the amount that penetrates and see through the light of two eyeglasses all changes to minimum from maximum, or vice versa.At any given time, the maximum that sees through the light of two eyeglasses is that this polarizing coating can omit when screen 210 penetrates polarised lights from the total amount of the light of display screen 210 and 252 ejaculations of selectable polarizing coating to any color cell; The minimum value of the amount of light is zero, and promptly two polarized lenses are all blocked fully from the light of screen 210 and 252 ejaculations of selectable polarizing coating.
