Embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperate appended graphicly, be described in detail below:
Figure 1A is the schematic top plan view of the 3 D image display system of the utility model one embodiment.See also Figure 1A, the 3 D image display system 100a of present embodiment comprises a display device 110 and a light valve glasses 120a, wherein light valve glasses 120a can alternately block human left eye sight line and right eye sight line, and display device 110 can alternately show the left eye picture that the human left eye of special confession is watched, and observes the right eye picture of seeing for human right specially.
The frequency of display device 110 Alternation Display left eye pictures and right eye picture can alternately to block the frequency of left eye sight line and right eye sight line consistent with light valve glasses 120a.When the audience put on light valve glasses 120a and views and admires the shown image of display device 110, light valve glasses 120a can in time block the sight line of audience's eyes, allows audience's left eye can only see the left eye picture separately, and right eye can only be seen the right eye picture separately.So, display device 110 can provide the audience to have the image of stereoscopic visual effect.
In the present embodiment, the display device 110 that is applied to 3 D image display system 100a comprises a liquid crystal display module 112 and a polarization optical element 114, and liquid crystal display module 112 has a linear polarization unit 112a.Linear polarization unit 112a can be a kind of linear polarizer in fact, and the linearly polarized light (linearlypolarized light) that therefore has single polarization direction can penetration line polarization unit 112a.
Liquid crystal display module 112 can produce image light L1 from linear polarization unit 112a, and image light L1 can contain left eye picture and right eye picture.Liquid crystal display module 112 the structure with displaying principle on all can be identical with existing liquid crystal display module.Specifically, liquid crystal display module 112 can comprise that linear polarization unit 112a and shows module body 112b, shows that wherein module body 112b comprises a liquid crystal display structure (not illustrating) and a module backlight (backlight module does not illustrate).
Between online polarization unit 112a in liquid crystal display structure position and the module backlight, module wherein backlight can provide the even brightness planar light beam, and liquid crystal display structure and linear polarization unit 112a are combined into a display panels (Liquid Crystal Display panel, LCD panel).When planar light beam penetrated display panels, liquid crystal display module 112 can produce image light L1 from linear polarization unit 112a, and then can demonstrate image on the online polarization unit 112a.
Polarization optical element 114 can change the polarization state of light, and can change the polarization state of light into nonlinear polarization from linear polarization.For example, polarization optical element 114 can change linearly polarized light into circularly polarized light (circularly polarized light), elliptically polarized light (elliptically polarized light) or nonpolarized light (non-polarized light), and wherein this nonpolarized light for example is natural light (naturallight).
Polarization optical element 114 is configured on the bang path of image light L1, and can be fitted on the linear polarization unit 112a.When image light L1 when linear polarization unit 112a sends, image light L1 can penetrate polarization optical element 114 immediately.The image light L1 that just sends from linear polarization unit 112a is a kind of linearly polarized light, and just the polarization state of Ci Shi image light L1 is a linear polarization.But, after image light L1 penetrated polarization optical element 114, polarization optical element 114 can change the polarization state of image light L1 into nonlinear polarization from linear polarization.
Polarization optical element 114 can be diffusion sheet or quarter-wave plate, and wherein the exiting surface of this diffusion sheet can present the outward appearance of cloudy surface or minute surface.When polarization optical element 114 was diffusion sheet, polarization optical element 114 can change image light L1 into natural light, and wherein polarization optical element 114 can be to utilize scattering (scattering) to change image light L1, makes image light become natural light.
When polarization optical element 114 was quarter-wave plate, polarization optical element 114 had fast axle and slow axis, and can change image light L1 into circularly polarized light or elliptically polarized light.Specifically, when the angle between the polarization direction of linear polarization unit 112a and the fast axle (or slow axis) equals 45 when spending, image light L1 can change circularly polarized light into.Angle between the polarization direction of linear polarization unit 112a and fast axle (or slow axis) is not equal to 45 degree, and when not overlapping with fast axle or slow axis, image light L1 then can change elliptically polarized light into.
Because polarization optical element 114 can change the polarization state of light, and can change the polarization state of light into nonlinear polarization from linear polarization, therefore penetrated the image light L1 of polarization optical element 114, its polarization state is a nonlinear polarization.That is to say that the image light L1 of this moment for example is circularly polarized light, elliptically polarized light or natural light, promptly the light of the image that manifested from polarization optical element 114 of display device 110 no longer is linearly polarized light.
The light valve glasses 120a that is applied to 3 D image display system 100a comprises two liquid crystal optics unit 122, a linear polarization unit 124a and a polarization optical element 126a.Linear polarization unit 124a is configured between polarization optical element 126a and these liquid crystal optics unit 122, and polarization optical element 126a can be fitted on the linear polarization unit 124a.After image light L1 sends from display device 110, can penetrate polarization optical element 126a, linear polarization unit 124a and a liquid crystal optics unit 122 wherein in regular turn.When image light L1 penetrated wherein a liquid crystal optics unit 122, another liquid crystal optics unit 122 can block image light L1.
Specifically, liquid crystal optics unit 122 has a plurality of liquid crystal molecules.These liquid crystal molecules can change arrangement mode via applying of electric field, and the arrangement mode of these liquid crystal molecules can allow liquid crystal optics unit 122 allow the light penetration of a certain polarization direction.When becoming a kind of linearly polarized light as image light L1 penetration line polarization unit 124a, by the electric field that is applied to these liquid crystal molecules, liquid crystal optics unit 122 can allow image light L1 to penetrate, or blocks image light L1.So, light valve glasses 120a can allow audience's left eye can only see the left eye picture separately, and right eye can only be seen the right eye picture separately.
The polarization optical element 126a of light valve glasses 120a can be same as the polarization optical element 114 of display device 110, be that polarization optical element 126a can be diffusion sheet or quarter-wave plate, wherein polarization optical element 126a can be the diffusion sheet with specular appearance.Therefore, polarization optical element 126a also can change the polarization state of light, and can penetrate polarization optical element 126a and linear polarization unit 124a from the image light L1 that polarization optical element 114 is sent.
Specifically, when the image light L1 that penetrated polarization optical element 114 is circularly polarized light, elliptically polarized light or natural light, and when polarization optical element 126a was diffusion sheet, image light L1 still was circularly polarized light, elliptically polarized light or natural light after penetrating polarization optical element 126a.
When the image light L 1 that penetrated polarization optical element 114 is circularly polarized light or elliptically polarized light, and polarization optical element 126a is when being quarter-wave plate, and image light L1 can become linearly polarized light after penetrating polarization optical element 126a.Yet become the image light L1 of linearly polarized light this moment, and its polarization direction is identical with the polarization direction of linear polarization unit 124a, so image light L1 energy penetration line polarization unit 124a, and be incident to liquid crystal optics unit 122.
Based on above-mentioned, because the polarization optical element 114 of display device 110 can change the polarization state of image light L1 into nonlinear polarization from linear polarization, for example change image light L1 into circularly polarized light, elliptically polarized light or natural light, so the angle between the two polarization direction of 112a, linear polarization unit of the linear polarization unit 124a of light valve glasses 120a and display device 110 can not influence image light L1 penetrating light valve glasses 120a.
In other words, even the angle between linear polarization unit 124a and the two polarization direction of 112a, linear polarization unit changes, the audience can not think that the brightness of image has unusual variation when putting on light valve glasses 120a and view and admire the image of display device 110.Therefore, the image of the tool stereoscopic visual effect that the 3 D image display system 100a of present embodiment is provided, its brightness can not be subjected to linear polarization unit 124a and the two polarization direction of 112a, linear polarization unit influences.
What deserves to be mentioned is, 3 D image display system 100a can also give up without polarization optical element 114,126a one of them.That is to say, in the embodiment shown in Figure 1A, can omit the polarization optical element 126a of light valve glasses 120a, or the polarization optical element 114 of omission display device 110, therefore 3 D image display system 100a can only adopt a polarization optical element, and this polarization optical element is to belong to light valve glasses 120a or display device 110.
When 3 D image display system 100a only adopted a polarization optical element (being polarization optical element 114 or 126a), display device 110 is show image normally still, and light valve glasses 120a also can in time block the sight line of audience's eyes.That is to say that even do not adopt polarization optical element 114 or 126a, generally speaking, 3 D image display system 100a also can normally operate.
Secondly, the two all can change the polarization state of light polarization optical element 114,126a, even therefore 3 D image display system 100a only adopt polarization optical element 114,126a one of them, the angle between the two polarization direction of 112a, linear polarization unit of the linear polarization unit 124a of light valve glasses 120a and display device 110 still can not influence image light L1 penetrating light valve glasses 120a.
Specifically, when 3 D image display system 100a only adopts polarization optical element 114, and do not adopt polarization optical element 126a, when just only polarization optical element 114 is shown equipment 110 and adopts, the image light L1 that display device 110 is sent from polarization optical element 114, its polarization state still is a nonlinear polarization, thus the linear polarization unit 124a of the still penetrable light valve glasses of image light L1 120a, and can not blocked by linear polarization unit 124a.
Otherwise, when 3 D image display system 100a only adopts polarization optical element 126a, and give up without polarization optical element 114, when just only polarization optical element 126a is adopted by light valve glasses 120a, though the image light L1 that display device 110 is sent is a linearly polarized light because of not penetrating polarization optical element 114, but polarization optical element 126a can change the polarization state of image light L1 into nonlinear polarization from linear polarization, for example image light L1 changes circularly polarized light into, elliptically polarized light or natural light, allow the image light L1 also can penetration line polarization unit 124a, and can not blocked by linear polarization unit 124a.
Hence one can see that, no matter be that display device 110 all possesses polarization optical element with light valve glasses 120a, or only display device 110 and light valve glasses 120a one of them just have polarization optical element, angle between linear polarization unit 124a and the two polarization direction of 112a, linear polarization unit can not influence image light L1 penetrating light valve glasses 120a, therefore the polarization optical element 114 shown in Figure 1A, 126a be only for illustrating, and non-limiting the utility model.
Figure 1B is the schematic top plan view of the 3 D image display system of another embodiment of the utility model.See also Figure 1B, the 3 D image display system 100b of present embodiment comprises a display device 110 and a light valve glasses 120b.Light valve glasses 120b is similar to the light valve glasses 120a of previous embodiment, and the difference of the two is: linear polarization unit 124b that light valve glasses 120b is included and the quantity of polarization optical element 126b are all two, shown in Figure 1B.
Particularly, these polarization optical elements 126b corresponds respectively to these liquid crystal optics unit 122, and these linear polarization unit 124b also corresponds respectively to these liquid crystal optics unit 122.These linear polarization unit 124b all is configured between polarization optical element 126b and the liquid crystal optics unit 122, and each polarization optical element 126b can fit in wherein a slice linear polarization unit 124b.So, image light L1 still can pass through these polarization optical elements 126b and linear polarization unit 124b in regular turn before being incident to liquid crystal optics unit 122.
3 D image display system 100b and 100a the two in advantage, effect and produce on the principle of stereoscopic visual effect all identically, no longer repeat to give unnecessary details below therefore.In addition, in other embodiments, these linear polarization unit 124b can replace to single linear polarization unit 124a, and these polarization optical elements 126b can replace to single polarization optical element 126a, so the two quantity of linear polarization unit 124b among Figure 1B and polarization optical element 126b is only for illustrating, and non-limiting the utility model.
Fig. 2 is the schematic top plan view of the 3 D image display system of another embodiment of the utility model.See also Fig. 2, the 3 D image display system 200 of present embodiment is similar in appearance to the 3 D image display system 100a shown in Figure 1A, and comprises a display device 210 and light valve glasses 220.Display device 210 and light valve glasses 220 the two structure are respectively similar in appearance to display device 110 and light valve glasses 120a, and only difference is: display device 210 is different from polarization optical element 114,126a with light valve glasses 220 the two polarization optical element that adopted 214,230.
Specifically, display device 210 comprises a liquid crystal display module 112 and a polarization optical element 214, and light valve glasses 220 comprise two liquid crystal optics unit 122, a linear polarization unit 124a and a polarization optical element 230.Polarization optical element 214,230 is all circular polarizing disk, and this circular polarizing disk comprises quarter-wave plate and linear polarizer.That is to say that polarization optical element 214 comprises a linear polarizer 214a and a quarter-wave plate 214b, and polarization optical element 230 comprises a linear polarizer 232 and a quarter-wave plate 234.
In display device 210, polarization optical element 214 can be fitted on the linear polarization unit 112a of liquid crystal display module 112, and linear polarizer 214a is between linear polarization unit 112a and quarter-wave plate 214b.Angle between the fast axle (or slow axis) of the polarization direction of linear polarizer 214a and quarter-wave plate 214b equals 45 degree, and the two polarization direction of linear polarizer 214a and linear polarization unit 112a is identical, therefore image light L1 can penetrate polarization optical element 230, and can be changed into circularly polarized light by quarter-wave plate 214b.
In light valve glasses 220, polarization optical element 230 can be fitted on the linear polarization unit 124a, and linear polarizer 232 is between linear polarization unit 124a and quarter-wave plate 234.Angle between the fast axle (or slow axis) of the polarization direction of linear polarizer 232 and quarter-wave plate 234 equals 45 degree, and the two polarization direction of linear polarizer 232 and linear polarization unit 124a is identical.
When the image light L1 that is sent from polarization optical element 214 was incident in light valve glasses 220, image light L1 can penetrate quarter-wave plate 234, linear polarizer 232 and linear polarization unit 124a in regular turn.At this moment, quarter-wave plate 234 can change image light L1 into linearly polarized light, and its polarization direction is identical with the polarization direction of linear polarizer 232, so image light L1 energy penetration line polaroid 232 and linear polarization unit 124a, and is incident to liquid crystal display mode group 112.
Hence one can see that, because the polarization optical element 214 of display device 210 can change image light L1 into circularly polarized light, so the angle between the two polarization direction of 112a, linear polarization unit of the linear polarization unit 124a of light valve glasses 220 and display device 210 also can not influence image light L1 penetrating light valve glasses 220.Therefore, the image of the tool stereoscopic visual effect that the 3 D image display system 200 of present embodiment is provided, its brightness also can not be subjected to linear polarization unit 124a and the two polarization direction of 112a, linear polarization unit influences.
In addition, identical with previous embodiment is, 3 D image display system 200 also can give up without polarization optical element 214,230 one of them, and only adopt single polarization optical element (for example polarization optical element 214 or 230).That is to say, in the embodiment shown in Figure 2, can omit the polarization optical element 230 of light valve glasses 220, and only adopt the polarization optical element 214 of display device 210; Or, can omit polarization optical element 214, and only adopt polarization optical element 230.
When 200 of 3 D image display systems adopted polarization optical elements (being polarization optical element 214 or 230), display device 210 is show image normally still, and light valve glasses 220 also can in time block the sight line of audience's eyes.Therefore, even do not adopt polarization optical element 214 or 230, generally speaking, 3 D image display system 200 equally also can normally operate.
In addition, polarization optical element 214,230 is all circular polarizing disk, thereby can both change the polarization state of light.Even 200 of 3 D image display systems adopt polarization optical element 214,230 one of them, angle between linear polarization unit 124a and the two polarization direction of 112a, linear polarization unit can not influence image light L1 penetrating light valve glasses 220, no matter so be that display device 210 all possesses polarization optical element with light valve glasses 220, or only display device 210 and light valve glasses 220 one of them just have polarization optical element, image light L1 still penetrable linear polarization unit 124a and not being blocked.
Special one carry be, though the quantity of the circular polarizing disk (being polarization optical element 230) that the light valve glasses 220 among Fig. 2 are included only is one, but in other embodiments, light valve glasses 220 also can comprise two circular polarizing disks, and these circular polarizing disks correspond respectively to these liquid crystal optics unit 122, and can fit in linear polarization unit 124a.Secondly, two linear polarization unit 124b shown in single replaceable one-tenth Figure 1B of linear polarization unit 124a shown in Figure 2.Hence one can see that, and the two quantity of the linear polarization unit 124a among Fig. 2 and polarization optical element 230 is only for illustrating, and non-limiting the utility model.
In sum, because the light valve glasses can alternately block human left eye sight line and right eye sight line, and display device can alternately show the left eye picture that the human left eye of special confession is watched, and observe the right eye picture of seeing for human right specially, therefore the 3 D image display system of the present utility model image that can provide the audience to have stereoscopic visual effect makes the audience can see stereopsis true to nature.
Secondly, 3 D image display system of the present utility model can adopt at least one polarization optical element, and this polarization optical element can change the image polarization state of light that display device produces, and allows the angle between the two polarization direction, linear polarization unit of the linear polarization unit of light valve glasses and display device can not influence image light penetrating the light valve glasses.Therefore, when the audience puts on the light valve glasses and watches the shown image of display device, the brightness of image can not be subjected to the influence of linear polarization unit and the two polarization direction, linear polarization unit and change, to avoid reducing the enjoyment that the audience enjoys stereoscopic visual effect because of the brightness ANOMALOUS VARIATIONS of image.
But above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; So long as according to spirit that this patent discloses done anyly be equal to change or modify, all fall into the scope that this patent comprises.
