Embodiment
First embodiment
Fig. 2 A is the synoptic diagram of 3 d display device first embodiment of the present invention.Please refer to Fig. 2 A, 3 d display device 200 is suitable for allowing the observer watch when wearing polaroid glasses 202, wherein polaroid glasses 202 have the first different circular polarization eyeglass 202A of polarization characteristic and the second circular polarization eyeglass 202B, and the composition member of the first circular polarization eyeglass 202A and the second circular polarization eyeglass 202B is shown in Fig. 2 A.The first circular polarization eyeglass 202A can be considered the combination of first quarter-wave plate 250, first half-wave plate 240 and eyeglass polaroid 270 (glass polarizer), and the second circular polarization eyeglass 202B can be considered the combination of second quarter-wave plate 260 and eyeglass polaroid 270.In addition, 3 d display device 200 comprises display panel 210, the 3rd quarter-wave plate 220 and patterning half-wave plate 230.In the present embodiment, patterning half-wave plate 230 is disposed between display panel 210 and the polaroid glasses 202, and the 3rd quarter-wave plate 220 is between display panel 210 and patterning half-wave plate 230.In addition, display panel 210 has panel polaroid 212 (panel polarizer), the image of being exported in order to polarization display panel 210, wherein display panel 210 can be enumerated as display panels, organic electric-excitation luminescent displaying panel, plasma display or Electrowetting display panel, and the present invention is not as limit.
Please continue A with reference to Fig. 2, display panel 210 has a plurality of pixel P that are arrayed, and the panel polaroid 212 between pixel P and polaroid glasses 202, wherein panel polaroid 212 has absorption axes A1, so that display panel 210 shown images are passing through the panel polaroid 212 linear polarization image I1 of the vertical A1 of output polarization directions afterwards.Then, linear polarization image I1 transfers circular polarization image I2 to after via the 3rd quarter-wave plate 220.Specifically, horizontal direction H with three-dimensional display is a benchmark, the optical axis A2 of the 3rd quarter-wave plate 220 in the present embodiment is for example vertical with horizontal direction H, has the angle that is essentially 45 degree between the optical axis A2 of the absorption axes A1 of panel polaroid 212 and the 3rd quarter-wave plate 220, in other words, present the angle that is essentially 45 degree between the optical axis A2 of the polarization direction of linear polarization image I1 and the 3rd quarter-wave plate 220 or between the polarization direction of linear polarization image I1 and the horizontal direction H, thus, shown in Fig. 2 A, linear polarization image I1 transfers dextropolarization image I2 to after via the 3rd quarter-wave plate 220.
In addition, patterning half-wave plate 230 has the different zone of two phase place retardation, wherein Qu Yu phase-delay quantity is essentially λ/2 (λ is a wavelength), the λ among the figure/2 phasic differences zone 230A for example, and another regional phase-delay quantity is essentially zero, for example the no phasic difference zone 230B among the figure.In detail, optical property and the tensile axis 232 of light after by patterning half-wave plate 230 has interdependent characteristic, thereby the direction that defines tensile axis among this λ/2 phasic differences zone 230A is the optical axis A3 direction of patterning half-wave plate.On the other hand, because the material molecule among the no phasic difference zone 230B is that any direction is arranged, thereby light can't influence the polarization characteristic of light after by no phasic difference zone 230B, is to level off to zero in fact with the phase-delay quantity that no phasic difference zone 230B is provided.Because factor in heating process (as the laser) processing of patterning half-wave plate 230, the angle theta 3 between optical axis A3 of patterning half-wave plate 230 (among λ/2 phasic differences zone 230A) and the horizontal direction H satisfies the following relationship formula, 3≤135 ° of 45 °≤θ.
What deserves to be mentioned is that the different zone of phase-delay quantity for example is to design with the aspect of interlaced arrangement in the patterning half-wave plate, and each zone is provided with corresponding to the pixel P on the display panel 210.For example, patterning half-wave plate 230 comprises a plurality of strip patterns, and the corresponding even column pixel P of strip pattern difference, or the corresponding odd column pixel P of difference.Certainly, a plurality of strip patterns also can be respectively corresponding even number line pixel P or odd-numbered line pixel P, and the present invention is the pattern kenel on the limiting pattern half-wave plate 230 not.Owing to have the different zone of phase-delay quantity on the patterning half-wave plate 230, make the shown image of display panel 210 by λ/2 phasic differences zone 230A and do not have and to isolate phase-delay quantity after the 230B of phasic difference zone and be essentially the image I3A of λ/2 and phase-delay quantity and level off to zero image I3B in fact.
More specifically, Fig. 2 B illustrates a kind of processing synoptic diagram of a kind of patterning half-wave plate when heating process (as laser).Please refer to Fig. 2 B, the production method of patterning half-wave plate 230 for example is that even half-wave plate (not illustrating) is provided earlier, this half-wave plate (not illustrating) is made up of the phasic difference film usually, and the optical property of phasic difference film can be adjusted by the arrangement mode that changes molecule in the phasic difference film.For example, whole molecule all stretches along same direction and arranges in the phasic difference film, makes half-wave plate (not illustrating) have tensile axis 232 comprehensively.Afterwards, carry out Patternized technique, on the regional area of this half-wave plate, shine, make and arranged arbitrarily again because of absorbing energy by the material molecule in the zone of laser radiation via laser.It should be noted that between the direction of the direction of scanning S of above-mentioned laser and tensile axis 232 angle in fact between 45 degree between 135 degree.Generally speaking, though can level off to zero so that the no phasic difference zone 230B of patterning half-wave plate 230 presents phase-delay quantity by above-mentioned means, but in fact patterning half-wave plate 230 still may make the residual phase-delay quantity slightly of no phasic difference zone 230B of patterning half-wave plate 230 because of technological factor, and these phase-delay quantities slightly make stereopsis produce color offset phenomenon easily.
It should be noted that, the composition member of the polaroid glasses 202 in the 3 d display device 200 of the present invention has suitable optical axis angle, can effectively compensate the color offset that image is produced after the appropriate combination when penetrating aforementioned the 3rd quarter-wave plate 220 and patterning half-wave plate 230, color difference eliminating.In detail, shown in Fig. 2 A, the absorption axes A7 of eyeglass polaroid 270 that constitutes the first circular polarization eyeglass 202A and the second circular polarization eyeglass 202B is perpendicular to the absorption axes A1 of panel polaroid 212.Specifically, in the assembly that constitutes the first circular polarization eyeglass 202A, angle between the optical axis A4 of first half-wave plate 240 and the optical axis A3 of patterning half-wave plate 230 is essentially 90 degree, and the angle between the optical axis A2 of the optical axis A5 of first quarter-wave plate 250 and the 3rd quarter-wave plate 220 is essentially 90 degree, therefore the observer can compensate the color offset of image, effectively color difference eliminating by first half-wave plate 240 among the first circular polarization eyeglass 202A and first quarter-wave plate 250.
In addition, please continue A with reference to Fig. 2, in the assembly that constitutes the second circular polarization eyeglass 202B, angle between the optical axis A2 of the optical axis A6 of second quarter-wave plate 260 and the 3rd quarter-wave plate 220 is in fact between 55 degree are spent to 125, angle between the optical axis A6 of above-mentioned second quarter-wave plate 260 of the suitable control of utilization and the optical axis A2 of the 3rd quarter-wave plate 220, phase delay slightly in the time of can eliminating the no phasic difference zone 230B of image by patterning half-wave plate 230, thereby the present invention allows small part, and no phasic difference zone 230B has the situation of phase-delay quantity slightly because of technological factor or other factors make, and can reach the color offset that compensates image, and then color difference eliminating by the optical axis direction of adjusting second quarter-wave plate 260.
For more abundant disclosure content of the present invention, a kind of display mechanism of 3 d display device 200 of the present invention will be described below.Fig. 3 and Fig. 4 are for illustrating in the 3 d display device of the present invention, the show state synoptic diagram that the shown image of display panel transmits via patterning half-wave plate zones of different respectively, wherein Fig. 3 is the show state of image via λ/2 phasic differences zone 230A, and Fig. 4 is the show state of image via no phasic difference zone 230B.
Please earlier with reference to Fig. 3 top, it illustrates the image polarization state synoptic diagram that image transmits via λ/2 phasic differences zone 230A of half-wave plate and the first circular polarization eyeglass 202A.Shown in Fig. 3 was above-listed, it was that linear polarization image I1 perpendicular to A1 changes into circular polarization image I2 before entering patterning half-wave plate 230 that λ/4 phase delays that the 3rd quarter-wave plate 220 is provided can make the polarization direction, as the dextropolarization image that is illustrated among the figure.Then, circular polarization image I2 enters the λ/2 phasic differences zone 230A of patterning half-wave plate 230, and λ/2 phase delays that patterning half-wave plate 230 is provided in λ/2 phasic differences zone 230A, can make circular polarization image I2 change into the opposite circular polarization image I3A of optical activity direction, enter the first circular polarization eyeglass 202A of polaroid glasses that the observer wears 202 again, after illustrating the λ/2 phasic differences zone 230A of dextropolarization image I2 among the figure, transfer left-hand polarization image I3A to via patterning half-wave plate 230.
Please continue top with reference to Fig. 3, the λ that first half-wave plate 240 is provided/2 phase delays can make circular polarization image I3A change into the opposite circular polarization image I4 of optical activity direction and enter first quarter-wave plate 250, in other words, left-hand polarization image I3A is via changing into dextropolarization image I4 once again after first half-wave plate 240.Then, dextropolarization image I4 can change into linear polarization image I5 by λ/4 phase delays that first quarter-wave plate 250 is provided before entering eyeglass polaroid 270, as shown in Figure 3, because it is parallel with the absorption axes A7 of eyeglass polaroid 270 to enter the polarization direction of the linear polarization image I5 before the eyeglass polaroid 270, therefore, linear polarization image I5 can't pass eyeglass polaroid 270 and the observed person observes, in other words, in this state, the observer sees through the first circular polarization eyeglass 202A can't observe image.
Then, please refer to Fig. 3 below, it illustrates same time observer and observes the image state that same pixel P presents through the second circular polarization eyeglass 202B, and the bang path of this image passes through λ/2 phasic differences zone 230A of patterning half-wave plate 230 equally.Shown in Fig. 3 is following, polarization state and the Fig. 3 before entering the second circular polarization eyeglass 202B is above-listed similar for image, and the polarization direction transferred to as being illustrated left-hand polarization image I3A among the figure by the 3rd quarter-wave plate 220 and patterning half-wave plate 230 by the linear polarization image I1 perpendicular to A1 originally afterwards.Afterwards, left-hand polarization image I3A is after λ/4 phase delays that provided via second quarter-wave plate 260, can transfer the linear polarization image I6 of the absorption axes A7 of the vertical eyeglass polaroid 270 in polarization direction to, thereby make the observer see through the second circular polarization eyeglass 202B can to observe image I7.Thus, in the operating mechanism as Fig. 3, the simple eye picture that the observed person observes can be separated by the combination of aforementioned optics diaphragm member.
Then, please refer to Fig. 4 top, it illustrates the image polarization state synoptic diagram that image transmits via the no phasic difference zone 230B of half-wave plate and the first circular polarization eyeglass 202A.Shown in Fig. 4 was above-listed, it was that linear polarization image I1 perpendicular to A1 changes into circular polarization image I2 before entering patterning half-wave plate 230 that λ/4 phase delays that the 3rd quarter-wave plate 220 is provided can make the polarization direction, as the dextropolarization image that is illustrated among the figure.Then, circular polarization image I2 keeps original polarization characteristic by the no phasic difference zone 230B of patterning half-wave plate 230, afterwards, λ/2 phase delays that first half-wave plate 240 is provided can make circular polarization image I3B change into the opposite circular polarization image I4 of optical activity direction and enter first quarter-wave plate 250 again, in other words, dextropolarization image I3B changes into left-hand polarization image I4 afterwards via first half-wave plate 240.Then, λ/4 phase delays that first quarter-wave plate 250 is provided make left-hand polarization image I4 transfer the linear polarization image I5 of the absorption axes A7 of the vertical eyeglass polaroid 270 in polarization direction to before entering eyeglass polaroid 270, thereby make the observer see through the first circular polarization eyeglass 202A and observe image I7.
