The following is a detailed description of the preferred embodiment and the following description of the accompanying drawings, and the following is a description of the present invention. FIG. 1 is a partial cross-sectional view of a light polarization control member according to an embodiment of the present invention. 2 is a top view of the 1/4th phase retardation layer in the light polarization control member of the lens 1. The light polarization control member 100 of the present embodiment includes a - 1/4 phase retardation layer. 110 and - a circularly polarized layer 12A. The first 1/4 phase retardation layer 110 has a plurality of first regions 112 and a plurality of second regions 4 and the first region 112 and the second region 114 are staggered (Fig. 2). In FIG. 1, the lower left side of the dotted line frame indicates the optical axes of the first area 112 and the second area j14, and the upper part of the broken line frame indicates the circular polarization layer 12 above the first area 112 and the first area 114. The circular polarization direction of the light that is allowed to pass. The angle between the optical axis A112 of the first region 112 and a reference direction ai is substantially -45 degrees, and the angle between the optical axis A114 of the second region 114 and the reference direction A10 is substantially 45 degrees. The circularly polarizing layer 120 is disposed on the first 1/4 phase retardation layer 110. The circularly polarizing layer 120 may allow light having a clockwise circular polarization to pass or allow light having a counterclockwise circular polarization to pass, and in the present embodiment, the circularly polarizing layer 120 allows light having a clockwise circular polarization to pass through, as shown in the figure. 1 is indicated by the upper part of the dotted line on the left. Further, each of the first regions 112 and each of the second regions 114 may be strip-shaped. 12 1363235 P060215LOZ1TW 22875twf.doc/n The left side of the dotted line on the right side of the figure T' indicates the polarization state of the partial ray corresponding to the first region 112 at the point indicated by the dotted arrow or the pass or not, and the dotted frame on the right The middle right side indicates the polarization state or the passage or absence of a part of the light corresponding to the second area indicated by the dotted arrow. Here, it is assumed that the light is linearly polarized before entering the first l/4 phase retardation layer 11〇, and the polarization is substantially parallel to the reference direction A1〇〇. After passing through the first zone 112 and the second zone ι14, the light will have a clockwise circular polarization and a counterclockwise circular polarization, respectively. Then, the circularly polarized light can be drawn through the circularly polarized layer 120, but the counterclockwise circularly polarized light cannot pass through the circularly polarized layer 120 to exhibit a dark state.

The junction material of the optical axis is 2, and the 1/4th phase retardation layer 110 may be perpendicular to the slow axis of the same material of the first region 112 and the second region (1) 13 1363235 P060215LOZ1TW 22S75twf.doc/n. In general, materials with refractive index anisotropy will have an axis and a spin axis (sl〇w axis). Among them, in the refractive index, (the fast axis is the same as the well, and the w is the negative material of the negative material, and the slow axis of the material is positive, which can be used to make the -i The /4 phase retardation layer 11〇, and the alignment of the liquid helium eight t slow axis can be achieved by using an alignment film or a light alignment. In addition, the first region 112 and the second region are positive and negative (Δη) The values may also be mutually different. In this case, as long as the material of the first material is parallel to be substantially parallel to the first axis, the result of the optical axis of the first-region m is determined to be the first axis of the material. Further, the first region 112 and the second region 114 may be formed of materials having different refractive index anisotropy (Δη), but the slow axes of the materials of the first region 112 and the second regions 114 are perpendicular to each other. ^ Again and again 'light polarization control member 1〇〇 may further include a substrate 13〇. The function of 130 is to support during the process of fabricating the light polarization control #.

Then, the line passing through the second 1/4 phase retardation layer 322 will form a line, the light in the direction η is perpendicular to the reference direction A1 (8), and the second 1/4 phase retardation layer 322 will form a line vibration. Direction η ± light in the flat reference direction A (10). After that, the light in the direction of the cardiac direction perpendicular to the reference direction A(10) can smoothly pass through the light-emitting layer 324, but the light having a linear polarization direction substantially parallel to the reference direction A100 is The dark state cannot be exhibited by the first linearly polarized layer 324. That is, the light polarization control member 300 produces a grating-like effect similarly to linearly polarized light. In addition, the second 1/4 phase retardation layer 322 has the advantage of being easy to fabricate, and the first linear polarization layer 324 can directly purchase a commercially available linear polarization film and attach it to the second 1/4 phase retardation layer. 322 can be. Further, the refractive index anisotropy (Δη) of the first region U2, the second region 114, and the second quarter phase retardation layer 322 may be positive or negative at the same time.

At this time, the slow axes of the -th region 112, the second region 114, and the second 1/4 phase retardation layer 322 are substantially parallel to each other. 5 is a partial cross-sectional view of the display of the embodiment of the present invention, and FIG. 6 is a schematic view of the display of FIG. 5 when the 3D image is displayed. Referring to FIG. 5, the display of the present embodiment includes a display panel and a first polarization control member 42, and the light polarization control member is disposed on the side of the display panel. Wherein the 'light polarization control member 42' is similar to the light polarization control member 300 of Fig. 4', with the difference that the light polarization control member is further increased by the second linearly polarizing layer 24G as shown. Of course, the surface vibration control member (4) can also be replaced by the light polarization (four) of the figure, or as appropriate according to the foregoing embodiments, 1363235 P060215LOZ1TW 22875twf.doc/n. Further, the display panel 41 is, for example, an organic electroluminescence element panel, a plasma display panel, or other form of display panel. The =5 6 6'-inch panel 41G has, for example, a staggered array of 1200 pixels and a plurality of rows of second pixels 414. The first element 412 in the basin is used to display the left eye face in the 3D image, and the second element 4f4 is used to display the right eye face in the 3D image.

The lighter with the left eye is passing through the second linear polarized dice t in the linearly polarized square shown in the dotted line on the right in Fig. 5, and then the light with the left eye The first-region ιΐ2 and the second-second 1-2 have a clockwise circular polarization and a counterclockwise circular polarization. Then, the linear polarization direction is substantially sag, and the late layer 322 is shaped to reflect the light in the reference direction A1GG, and the inverse I line (four) after the second 1/4 phase retardation layer 322 is formed in the reference direction Α1. The light of °°. After that, the light of the first line is offset; the light of the A1GG in the direction of the f can be smoothly opened, but the line is biased and the left side of the user is transmitted to the left of the user. The light in the reference direction A100 is the right eye. The transmission of the left eye face to the user for the vibration layer 324 passes = control == the area corresponding to the lion with the right eye face is issued] The light can transmit the right eye face to the right eye of the user through the first region 112 gray, and the remaining portion 17 1363235 P060215LOZ1TW 22875twf.doc/n can not pass the right region of the second region 114 The left eye is transmitted to the user. Therefore, the left eye face displayed by the first pixel 412 of the display panel 41 and the right eye face displayed by the second pixel 414 can be respectively transmitted to the left eye of the user. And the right eye, thereby achieving the purpose of displaying the 3D image. FIG. 7A and FIG. 7B are respectively another embodiment of the present invention. A partial cross-sectional view of the display of the embodiment in the 3D mode and the 2D mode. Referring to FIG. 7A, FIG. 7B, the display 5 of the embodiment is similar to the display 4 of FIG. 5, and the difference is that the display 500 further includes a display. The light polarization switching member 53 is disposed between the first linear polarization layer 240 and the first 1/4 phase retardation layer 11A. In other words, the light polarization control member 52 of the present embodiment is similar to the light polarization control of FIG. The second linear polarization layer 240 is separated from the light polarization control member 52. Of course, the second linear polarization layer 240 can also be directly attached to the lower surface of the light polarization switching member 530 or the display panel 41A. The light polarization switching member 530 has a plurality of third regions 532 and a plurality of fourth regions 534 corresponding to the first region 丨12 and the second region 114, respectively. When the light polarization switching member 530 is in a first state, The linear polarization directions of the rays of the third region 532 and the fourth region 534 are unchanged, as shown in Fig. 7A. When the light polarization switching member 530 is in a second state, the linear polarization direction of the light passing through the third region 532 does not change. The linear polarization direction of the light of the fourth zone 534 is rotated by 9 degrees. 7B, the light polarization switching member 530 is composed of, for example, a liquid crystal panel in an electrically controllable switching state, wherein the upper and lower sides of the liquid crystal layer in the third region 532 may have a single-sided electrode or both sides without electrodes, and the fourth region 534 The upper and lower layers of the liquid crystal layer have electrodes on both sides, for example, the liquid layer of the liquid crystal layer of the fourth region 534 is 1363235 P060215LOZ1TW 22875twf.d〇c/n crystal molecules can be changed by the electric field (4), so that it will pass The linear polarization direction of the light of the fourth zone 534 is rotated by 9 degrees. Referring to FIG. 7A, when the light polarization switching member 53() is in the first position, the polarization direction does not change because the light passes through the light polarization switching member. Therefore, the display 500 can be as shown in FIG. Display 3D images as usual. Referring to FIG. 7B, when the light polarization switching member 53 is in the second shape, the polarization direction is rotated by 9 degrees when the light passes through the fourth region 534, so that the light polarization control member 52 can be subsequently passed through. The portion of the second region ι 4, while the light passing through the third region 532 and the first state still pass through the portion of the light polarization control member 520 corresponding to the first region 112.

The light provided by the backlight module 61 is shown in the dotted line on the right in Fig. 8 to become linearly polarized light in a parallel direction after passing through the first linearly polarizing layer 324. Then, the linearly polarized light passes through the second quarter phase retardation layer 322 to become clockwise circularly polarized light. Thereafter, the clockwise circularly polarized light passes through the first region 112 to become linearly polarized light in the vertical direction, and the clockwise circularly polarized light passes through the second region 114 to become linearly polarized light in the parallel direction. Only the linearly polarized light in the parallel direction is allowed to pass, so only the light passing through the first region 112 can finally enter the liquid crystal display panel 620, and the light passing through the second region 114 will eventually fail to enter the liquid crystal display panel 620. By this, the liquid crystal display 600 can also achieve the purpose of displaying 3D images.

FIG. 12, the light of the embodiment The polarization control member & (9) includes a 1/4 phase retardation layer 122A and a circular polarization layer 121. The vibration layer 1210 has a plurality of first regions 1212 and a plurality of second regions 1214, and the 21st 1363235 P060215LOZ1TW 22875twf.doc/ n A region 1212 and a second region 1214 are staggered (Fig. 13). Below the dotted box 10 on the left side of Fig. 12' is a circular polarization layer 1210 of the first region 1212 and the second region·1214. The circular polarization direction of the light allowed to pass, and the upper portion of the dashed box indicates the optical axis above the first region 1212 and the second region 1214. The first region 1212 allows light having a clockwise circular polarization to pass, while the second region 1214 allows light having a counterclockwise circular polarization to pass through. The 1/4 phase retardation layer 1220 is disposed on the circularly polarizing layer 1210. In the present embodiment, each of the first region 1212 and each of the second regions 1214 is a strip shape. , but not limited to this. In Figure 12, the dotted line on the right The left side of the box indicates the polarization state of the partial ray corresponding to the first zone 1212 at the point indicated by the dotted arrow or the passage of the light, and the right side of the dotted frame indicates the partial ray corresponding to the second zone 1214. The state of polarization at the point indicated by the dashed arrow or pass or fail. Here, the polarization state before the light enters the circularly polarizing layer 1210 may be confusing, but the light rays passing through the first region 1212 and the second region 1214 will have only Clockwise circular polarization and counterclockwise circular polarization. Then, the clockwise circularly polarized light passes through the 1/4 phase retardation layer 丨22〇 and becomes a light perpendicular to a reference direction A200, while the counterclockwise circularly polarized light passes through 1/ After the phase retardation layer 1220, the light rays are parallel to a reference direction A2〇〇. That is, the light rays entering the circular polarization layer 1210 and being emitted from the 1/4 phase retardation layer 1220 become linearly polarized light, and the linear polarization The light direction may be different according to the first region 1212 or the second region 1214, and perpendicular to each other. Further, the light polarization control member 1200 may further include a substrate 1230. The substrate 1230 functions to fabricate the light polarization control member 12 22 1363235 P060215L0Z1TW 22875twf.doc/n is provided in the process of 〇. In this embodiment, the circularly polarizing layer 1210 is disposed between the substrate 1230 and the I 〆 phase retardation layer 1220. However, the position of the substrate 123 也 can also be appropriately adjusted. The material is mainly provided in the process of fabricating the light polarization control member 1200. The material of the substrate 1230 is, for example, glass or other suitable light transmissive material. For example, in the production of the light polarization control member 12, A non-photoreactive palm material may be deposited on the substrate 1230, for example, a material of the Merck product type RgH and a photo-induced modification of the spinning twisting power of a mixture of chiral dopants. Next, the film was cured. Thereafter, a portion of the film corresponding to the first region 1212 or the second region 1214 is exposed through the mask to change the palm of the exposed film, for example, from right-handed to left-handed. Thus, the circularly polarizing layer 1210 can be completed. Finally, a layer of 1/4 phase retardation layer is applied to make the slow axis in a certain direction, that is, all processes are completed. Figure 14 is a partial cross-sectional view showing a light polarization control member according to still another embodiment of the present invention. Referring to Fig. 14, the light polarization control member 14A of the present embodiment is similar to the light polarization control member 12A of Fig. 12, except that the light member 1400 further includes a linear polarization layer 144A. The 1/4 phase retardation layer is disposed between the circularly polarizing layer 1210 and the linearly polarizing layer 144A. After Μ 4. The optical axis. It is substantially parallel to the reference direction Α2. . The optical axis Α 1440 of the linear vibration layer 1440 and the optical axis Α 1220 of the 1/4 phase retardation layer 122 are substantially 45 degrees as shown in the dashed box on the left side of the figure. Therefore, the linearly polarized light passing through the first region 1212 and the 1/4 phase retardation layer 122 in sequence can smoothly pass through the linear polarization layer 144, but is in a bright state, but passes through 23 1363235 p〇60215LOZ1TW 22875twf.doc/n. The linearly polarized light of the second region 1214 and the 1/4 phase retardation layer 122 is unable to pass through the linearly polarized layer 1440 to exhibit a dark state. That is, the light polarization control member 1200 produces a grating-like effect for light. Figure 15 is a partial cross-sectional schematic view of a display in accordance with another embodiment of the present invention. Referring to FIG. 15, the display 15A of the present embodiment includes a display panel 1510 and a light polarization control member 1400 of FIG. 14, and the light polarization control member 1400 is disposed on one side of the display panel 1510. The display panel 151, for example, φ is an organic electroluminescent element panel, a plasma display panel, or other form of display panel. Since the light polarization control member 1200 produces a grating-like effect for light, the left eye face and the right eye written by the display panel 1510 can also be transmitted to the left and right eyes of the user respectively, thereby achieving display 3D. The purpose of the image. 16 and 17 are partial cross-sectional views showing a display in a 3 〇 mode and a 2D mode, respectively, according to still another embodiment of the present invention. Referring to FIG. 16 and FIG. 17, the display 1600 of the present embodiment is similar to the display 15 of FIG. 15, except that the display benefit 1600 further includes a light polarization switching member 1630 disposed on the linear polarization layer 1440 and 1/4. Between the phase retardation layers 122〇. The light polarization switching member 1630 has a plurality of second regions 1632 and a plurality of fourth regions 1634 corresponding to the first region 1212 and the second region 1214, respectively. When the light polarization switching member 163 is in a first state, the linear polarization direction of the light passing through the third region 1632 and the fourth region 1634 is unchanged, as shown in FIG. When the light polarization switching member 163 is in a second state, the linear polarization direction of the light passing through the third region 1632 does not change, and the linear polarization direction of the light passing through the fourth region 1634 is rotated by 9 degrees, as shown in Fig. Π. The light polarization switching member 163 is, for example, electrically switchable. 24 1363235 P060215L021TW 22S75twf_d〇c/n wherein the liquid crystal layer in the third region 1632 can be on the upper and lower sides: 丨: two: no electrodes on the sides, and fourth The liquid of the liquid crystal layer in the region 1634 has electrodes. Therefore, the 液晶# function of the liquid crystal layer of the fourth zone is to change the direction of the line, for example, to rotate the linear polarization direction of the light passing through the fourth zone by 90 degrees. Please refer to ® 16, when the light polarization switching member 1630 is in the first state, since the light is changed by the light offset (4), the polarization direction will not be changed. Therefore, the display 16 can be as shown in the display of FIG. Display 3D images. Referring to FIG. 17, when the light polarization switching device is in the second state, 'because the light passes through the fourth region 1634, the polarization direction is rotated by 9 degrees, so that the light polarization layer 1440 can pass through the third region. The light of 1632 is still difficult to pass through the linear polarization layer as in the first state. In other words, when the light polarization switching member 163 () is in the second state, the screen displayed by the entire display panel 1510 is transmitted to the left and right eyes of the user, and becomes a mode in which the jD is not displayed. Accordingly, the display 16 of the present embodiment can be switched between the display mode and the 3D display mode. Moreover, the switching of the display mode of the display surface can be achieved by electronic control.

Polarization layer M40. The light provided by the backlight module 181 is first passed through the circular polarization layer 121 of the light polarization control member 1200 and then advanced into the 1/4 phase retardation layer 1220. As shown in the dashed box on the right in Fig. 18, the light provided by the backlight module 1810 will have only clockwise circular polarization and counterclockwise circular polarization after passing through the first region 1212 and the second region 1214, respectively. Then, the clockwise circularly polarized light passes through the 1/4 phase retardation layer 1220 and becomes a vertical φ linearly polarized light, and the counterclockwise circularly polarized light passes through the 1/4 phase retardation layer 1220 to become a parallel linear polarization. Light. Since the linearly polarizing layer 144 〇 only allows the linearly polarized light of the vertical direction to pass, only the light passing through the first region 1212 can finally enter the liquid crystal display panel 丨 82 〇, and the light passing through the second region 1214 will eventually fail to enter the liquid crystal display panel. 182〇. Thereby, the liquid crystal display 1800 can also achieve the purpose of displaying 3D images.
