Particularly, please with reference to Fig. 3 to Fig. 5, a kind of polaroid glasses formula 3 d display device 20 that the embodiment of the invention provides is applicable to watches stereo-picture when letting the observer wear polaroid glasses 220.Wherein, polaroid glasses formula 3 d display device 20 for example comprises display panel 240, twin shaft quarter-wave plate 260, patterning half-wave plate 280 and polaroid glasses 220.
As shown in Figure 3, the image of display panel 240 outputs is the linear polarization image, and it comprises linear polarization left-eye image part and linear polarization eye image part that the polarization direction is identical.Please with reference to Fig. 3, display panel 240 for example comprises display panels 242 and panel polaroid 244, and the image of being exported by panel polaroid 244 polarization display panels 242 forms linear polarization image I 1.Certainly, display panel 240 can also be display panels such as the organic electroluminescent display panel of other exportable linear polarization images, plasma display, and the present invention is not as limit.In the present embodiment, the panel polaroid 244 of display panel 240 for example has the light transmission shaft A1 that is parallel to horizontal direction H.
Twin shaft quarter-wave plate 260 is disposed between display panel 240 and the polaroid glasses 220; What for example present embodiment was shown in Figure 3 further is disposed between display panel 240 and the patterning half-wave plate 280, with the assembling and the making of convenient whole polaroid glasses formula 3 d display device 20.In the present embodiment, the slow-axis direction A2 of twin shaft quarter-wave plate 260 is 45 degree with the angle of horizontal direction H for example, is 45 degree with the angle of the polarization direction (the light transmission shaft A1 of corresponding panel polaroid 244) of the linear polarization image I 1 of display panel 240 outputs promptly also.The linear polarization image I 1 of display panel 240 output converts for example right-hand circular polarization image I 2 of circular polarization image to after via twin shaft quarter-wave plate 260, and it comprises right-hand circular polarization left-eye image part and right-hand circular polarization eye image part.
Patterning half-wave plate 280 is disposed between display panel 240 and the polaroid glasses 220; It has different first area 280A of phase-delay quantity and second area 280B; The phase-delay quantity of first area 280A is 1/2nd wavelength, and the phase-delay quantity of second area 280B is zero.In the present embodiment, first area 280A is the half-wave retardation list structure, and second area 280B is a transparent configuration, and both for example vertically alternately arrange odd number behavior first area 280A, even number behavior second area 280B each other.Right-hand circular polarization left-eye image part in the right-hand circular polarization image I 2 is corresponding to convert Left-hand circular polarization image I 3A to through first area 280A, converts right-hand circular polarization image I 3B and right-hand circular polarization eye image part is corresponding to through second area 280B.The slow-axis direction A3 of first area 280A is 45 degree with the angle of horizontal direction H for example, is 45 degree with the angle of the polarization direction (the light transmission shaft A1 of corresponding panel polaroid 244) of the linear polarization image of display panel 240 outputs promptly also.
Polaroid glasses 220 have different left eyeglass lens 220A of polarization characteristic and right eye eyeglass 220B.Wherein, left eyeglass lens 220A comprises twin shaft quarter-wave plate 221 and polaroid 222; Right eye eyeglass 220B comprises full half-wave plate 223, twin shaft quarter-wave plate 224 and polaroid 225; At this, full half-wave plate 223 also is that full half-wave plate 223 is not patterned, so be referred to as full half-wave plate for patterning half-wave plate 280.
As shown in Figure 4, the light transmission shaft A5 of the polaroid 222 of left eyeglass lens 220A for example is orthogonal to horizontal direction H, also promptly with polarization direction (the light transmission shaft A1 of the corresponding panel polaroid 244) quadrature of the linear polarization image I 1 of display panel 240 output.The slow-axis direction A4 of twin shaft quarter-wave plate 221 is 135 degree with the angle of horizontal direction H for example, that is to say that the slow-axis direction A4 of twin shaft quarter-wave plate 221 is orthogonal to the slow-axis direction A2 of twin shaft quarter-wave plate 260 in the present embodiment.The twin shaft quarter-wave plate 221,260 of quadrature can prevent outer (off-axis) light leak of the axle that causes because of the azimuthal change of slow axis, can reduce crosstalking under the oblique incidence situation like this, improves the stereo display image quality.
As shown in Figure 5, the light transmission shaft A8 of the polaroid 225 of right eye eyeglass 220B is orthogonal to horizontal direction H, also promptly with polarization direction (the light transmission shaft A1 of the corresponding panel polaroid 244) quadrature of the linear polarization image I 1 of display panel 240 output.The slow-axis direction A6 of full half-wave plate 223 is 135 degree with the angle of horizontal direction H for example, thus with the slow-axis direction A3 quadrature of patterning half-wave plate 280.The slow-axis direction A7 of twin shaft quarter-wave plate 224 is 135 degree with the angle of horizontal direction H for example, that is to say that the slow-axis direction A7 of twin shaft quarter-wave plate 224 is orthogonal to the slow-axis direction A2 of twin shaft quarter-wave plate 260 in the present embodiment.The twin shaft quarter-wave plate 224,260 of quadrature can prevent the outer light leak of axle that causes because of the azimuthal change of slow axis from can reduce crosstalking under the oblique incidence situation like this, raising stereo display image quality.
In addition, for the outer light of axle, when at the slow axis position angle being 45 degree directions (φ=45 °) or 45 degree odd directions (consider outside the axle light light leak serious situation), the slow-axis direction of twin shaft quarter-wave plate can be expressed as:
Wherein,
For the twin shaft medium, the twin shaft factor Nz that describes the biaxial optical characteristic can be expressed as Nz=(n

x＞n
yThe slow axis deviation angle of twin shaft quarter-wave plate (shift angle) Δ Ψ=Ψ (θ
0)-Ψ (θ
0=0 °, different along with different Nz.As shown in Figure 6, Nz＞0.5 o'clock, the slow axis deviation angle is a negative value, Nz＜0.5 o'clock, the slow axis deviation angle be on the occasion of; During Nz=0.5, slow-axis direction almost constant (being Δ Ψ ≈ 0), so the twin shaft factor of twin shaft quarter-wave plate 221,224 and 260 is got 0.5 o'clock compensation effect the best; Among Fig. 6; When Nz=1, be the single shaft quarter-wave plate, visible its slow axis deviation angle is bigger, and compensation effect is not good to be had only when Nz=0.5 and (be the twin shaft quarter-wave plate); It is best that its slow-axis direction almost constant (being Δ Ψ ≈ 0), the twin shaft factor are got 0.5 o'clock compensation effect.But the present invention is not as limit, as long as the selected twin shaft factor can be reached deviser's design object.
Please refer again to Fig. 3 and Fig. 5, the right eye eyeglass 220B in the present embodiment can also further increase an optical compensating gage, and that adopt in the present embodiment is positive C-axle optical compensating gage 226 (n
x=n
y＜n
z); Positive C-axle optical compensating gage 226 can be disposed at and further compensate light leak between twin shaft quarter-wave plate 224 and the polaroid 225; With further raising eye image quality (can find that from Fig. 2 the suffered degree of crosstalk of the eye image degree of crosstalk suffered with respect to left-eye image is more serious).
For the ease of understanding the present invention, below will combine Fig. 7 and Fig. 8 that a kind of display mechanism of embodiment of the invention polaroid glasses formula 3 d display device 20 is described.The synoptic diagram that presents dark attitude when right eye was seen the odd-numbered line image when Fig. 7 was to use the polaroid glasses formula 3 d display device 20 of the embodiment of the invention.The synoptic diagram that presents dark attitude when left eye was seen the even number line image when Fig. 8 was to use the polaroid glasses formula 3 d display device 20 of the embodiment of the invention.
Please with reference to Fig. 7, it is that the polarization image I1 that is parallel to horizontal direction H converts circular polarization image I 2 into that the quarter-wave phase delay that twin shaft quarter-wave plate 260 is provided can make the polarization direction, is the right-hand circular polarization image in the present embodiment.Behind the first area 280A (corresponding odd-numbered line image) of right-hand circular polarization image I 2 through patterning half-wave plate 280, because the half-wave phase delay that first area 280A is provided makes right-hand circular polarization image I 2 convert Left-hand circular polarization image I 3A to.Then, Left-hand circular polarization image I 3A has got into the full half-wave plate 223 of the right eye eyeglass 220B on the polaroid glasses that the user wore 220, converts right-hand circular polarization image I 4 to through full half-wave plate 223 back Left-hand circular polarization image I 3A.Right-hand circular polarization image I 4 through with the twin shaft quarter-wave plate 224 of twin shaft quarter-wave plate 260 quadratures after convert horizontal linear polarization image I 5 again to.Horizontal linear polarization image I 5 is a horizontal linear polarization image I 6 through positive C-axle optical compensating gage 226 compensation backs, gets into polaroid 225 at last.Because the light transmission shaft A8 of polaroid 225 is perpendicular to horizontal direction H, therefore, horizontal linear polarization image I 6 can't be passed polaroid 225 and the person of being used observes; Under this state, the user can't observe the left-eye image part (odd-numbered line image) that is seen through by first area 280A through right eye eyeglass 220B; That is to say, can't see the linear polarization left-eye image part of display panel 240 outputs through right eye eyeglass 220B.
Please with reference to Fig. 8; It is that the polarization image I1 that is parallel to horizontal direction H converts right-hand circular polarization image I 2 into that the quarter-wave phase delay that twin shaft quarter-wave plate 260 is provided can make the polarization direction, still keeps original polarization characteristic to form right-hand circular polarization image I 3B behind the second area 280B of right-hand circular polarization image I 2 through patterning half-wave plate 280.Then; Right-hand circular polarization image I 3B gets into the left eyeglass lens 220A on the polaroid glasses 220 that the user wore; Twin shaft quarter-wave plate 221 back right-hand circular polarization image I 3B through with twin shaft quarter-wave plate 260 quadratures convert horizontal linear polarization image I 7 to, get into polaroid 222 at last.Because the light transmission shaft A5 of polaroid 222 is orthogonal to horizontal direction H, therefore, horizontal linear polarization image I 7 can't be passed polaroid 222 and the person of being used observes; Under this state, the user can't observe the eye image part (even number line image) that is seen through by second area 280B through left eyeglass lens 220A, that is to say the linear polarization eye image part that can't see display panel 240 outputs through left eyeglass lens 220A.
This shows; The polaroid glasses formula 3 d display device 20 that the embodiment of the invention provided can be via the twin shaft quarter- wave plate 221 and 224 that is provided with respectively at left eyeglass lens 220A and right eye eyeglass 220B with twin shaft quarter-wave plate 260 quadratures; The outer light leak of the caused axle of the azimuthal change of slow axis when utilizing the twin shaft quarter-wave plate of slow-axis direction quadrature to avoid using quadrature single shaft quarter-wave plate in the prior art; The linear polarization left-eye image part of the first area 280A of feasible corresponding process patterning half-wave plate 280 is not used person's right eye and sees; And see through the left eye that the linear polarization eye image part of the second area 280B of patterning half-wave plate 280 is not used the person, just be reduced in crosstalking that the phase deviation that causes under the light oblique incidence situation etc. causes.Fig. 9 is to use the analog result figure that crosstalks of the polaroid glasses formula 3 d display device of the embodiment of the invention; The thickness of glass substrate near user's eyes one side of hypothesis display panel 240 is zero (so-called in the industry at once " in cell " structure during simulation; Be equivalent among the present invention twin shaft quarter-wave plate 260 and all be positioned at display panels inside) with patterning half-wave plate 280; Among the analog result figure that crosstalks as shown in Figure 9, the visual angle corresponds respectively to four visual angles of 90,270,180 and 0 degree among the figure up and down, and the line among the figure is an isoluminance curve; The digitized representation of the marking ratio of image of crosstalking on the figure intermediate light curve with respect to the script image; Be the ratio of interfering picture with respect to ideal image, the more little representative of this ratio is crosstalked more little, and picture quality is good more.Can know with Fig. 2 through comparison diagram 9; The area of the isoluminance curve institute region of crosstalking less among the analog result figure that crosstalks of the embodiment of the invention improves a lot than prior art, and especially eye image is compared prior art and made the reduction greatly of crosstalking; Crosstalk in the visual angle up and down of right and left eyes bigger reduction is all arranged; Therefore, present embodiment can effectively reduce crosstalks, and improves the stereo display image quality.
It is understandable that; The polarization direction of the linear polarization image I 1 of display panel 240 outputs also can be orthogonal to horizontal direction H or be arbitrarily angled with horizontal direction H; And each direction of principal axis of each optical sheet can design according to aforementioned criteria in the three-dimensional display device 20, to eliminate crosstalking that the phase deviation that causes when the light oblique incidence etc. causes.In addition; Need to prove; Left eyeglass lens that the foregoing description provides and right eye eyeglass and pairing separately panel side wave plate structure thereof all can be exchanged simultaneously; Wherein each direction of principal axis of each optical sheet is merely the Design Theory value; And may there be a little making error in each direction of principal axis in the process of each optical sheet of actual fabrication; For example the light transmission shaft of the slow-axis direction quadrature of the slow-axis direction of the full half-wave plate of not strict qualification and patterning half-wave plate, first polaroid is parallel with the light transmission shaft of second polaroid and just to give the angle of polarization direction of slow-axis direction and linear polarization image of polarization direction, the 3rd twin shaft quarter-wave plate of linear polarization image be that the angle of slow-axis direction and the polarization direction of linear polarization image of 45 degree, full half-wave plate is 135 to spend etc. among the present invention; Wherein quadrature, the number of degrees parallel and angle are not strict is limited to this; This instructions only is that example describes with the preferred forms, in the actual fabrication process, perhaps also a little deviation can occur based on other considerations with upper angle, as long as do not influence enforcement of the present invention; With upper angle in the actual fabrication process or based on other consider the situation of a little deviation is appearred, all fall within the protection domain of claims of the present invention.In addition, those skilled in the art's putting in order and/or each direction of principal axis of each optical sheet between can also each optical sheet of appropriate change all can as long as can reach the present invention's the purpose of improving the picture degree of crosstalk.
The above only is preferred embodiment of the present invention, is not the present invention is done any pro forma restriction; Though the present invention discloses as above with preferred embodiment; Yet be not in order to limiting the present invention, anyly be familiar with the professional and technical personnel, in not breaking away from technical scheme scope of the present invention; When the technology contents of above-mentioned announcement capable of using is made a little change or is modified to the equivalent embodiment of equivalent variations; In every case be not break away from technical scheme content of the present invention, to any simple modification, equivalent variations and modification that above embodiment did, all still belong in the scope of technical scheme of the present invention according to technical spirit of the present invention.
