With the advancement of technology, display devices are constantly innovating, and the demand for images is becoming more diverse. Although the current public service has high resolution, riding ratio and high brightness and high quality specifications, the face can still be limited to the two-dimensional plane, and can not be presented as a second image. The visual miscellaneous of the space of one and the other, ##The left and right eye are divided into two images with different parallax in the same image. 'There will be a stereoscopic image. The vertical image display technology is divided into two types.昼: The polarized one = should 'take two images at the same time in different polarization directions, and make ^ stereo polarized glasses' to see the stereo image. The other is the Auten e_pie Display technology, which is a front panel panel = lens or grating 'viewing different two-sided surfaces by different angles viewed by the left and right eyes to produce a stereoscopic image' However, this technology has a problem of reduced resolution. Although the above autostereoscopic display technology does not require wearing polarized glasses = stereo image, it has many problems. For example, the resolution of Miyazaki will decrease due to the convex lens or light _ setting, and the effect of the stereoscopic image will change with the user's viewing inspection (usually a spider can be used to have a good display effect). Causes discomfort in the eyes of the manufacturer. 5 201024798

-1TW 24870twf.doc/d [Invention] The present invention provides a stereoscopic image display with different polarization images, so that the user can produce a product because of the user's viewing position and angle. The problem that the body resolution is lowered and the kneading quality is deteriorated occurs. & - 疋 Because the present invention further provides a stereoscopic image display method, f:;: the display quality of the system allows the user to watch the stereoscopic image: H: H is reduced and the singularity of the singularity occurs. The present invention proposes - the type of reading _ line 昼 与 - - - - - - - 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并 并Polarized direction. Viewing the spectacle lens and the right spectacle lens, the left spectacle lens has a pupil direction, wherein the third polarized light side is 冋 and the fourth polarized light direction is the same as the second polarized light direction. The present invention further provides a stereoscopic image display method, which comprises dividing a left eye picture and a right eye picture on the first image plane. After 1 then, the left black and the left eye are sequentially displayed.妾=Polarizes the left eye image to have a first polarization direction. After the iron, =_ time in time, the second black and right eye images are displayed in sequence. Tr Ιί, the face is polarized so that it has a second polarization direction. Finally, ki, a left-eye lens having a third polarization direction and a right-eye lens having a fourth polarization side 201024798_Z1TW 2487Dtwf.d〇c/d direction, wherein the third polarization direction is opposite to the first-polarization direction and the fourth polarization direction Same as the second polarization direction. The invention uses a liquid crystal panel to polarize the image of the image to have different polarization directions, and rotates the left and right eyes 3 in a frequency-doubled manner, so that the human eye can see the effect of the stereoscopic image, and the pupil image is analyzed. ^The angle of view will not be affected. The above features and advantages of the present invention will become more apparent and easy to understand. [Embodiment] Fig. 1A is a view showing the composition of a read image display system of the present invention. The @1A towel's stereoscopic image display system 1 includes a display of dryness and crying. The display includes a display module 120 and liquid crystal polarized light: /, the middle liquid crystal polarizing panel 130 is disposed on the side of the display module 12, that is, the liquid crystal polarizing panel 130 is disposed between the display mold 120 and the user of the web 140. In this implementation, the display (10) divides the image displayed by the frame time into the left eye and the right eye to present 'Let's left; 6: Eyes to the left (4) ^ Mixed effect. That is to say, the display 110 "is considered to be two equal sub-frame times, for example, the frame time is · frame time is 1/12 〇 seconds, that is, the frequency is displayed in a multiplier manner === is ' The display 110 will be biased at the sub-frame time display: ΐ: and display the polarized right eye & face at another adjacent sub-frame time, causing the user wearing the view mirror 140 to produce an image. The difference is seen in the stereo image. The money is poor and 7.1TW 24870twf.doc/d 201024798 Now continue to refer to FIG. 1A to illustrate the stereoscopic image display system showing that M UG is 11 when the internal sub-frame is displayed = ;:: :, :: Frequency mode, 睥 千 Γ Γ Γ Γ Γ ΐ ΐ Γ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ ΐ 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 。 It is said that each shadow is composed of the left eye and the right eye, so the sub-frame time mdan and T12 represent the age of 12 (), the left side of the image-image surface and the right eye The time of the surface. In the above, in the polarization part, the display 11 is polarized by the internal liquid crystal polarizing panel 13G. The main surface displayed by 12(). At the sub-frame time T11, the liquid crystal polarizing panel 13 turns the polarization direction of the left (four) plane by using the turning of the internal liquid crystal molecules, so that the left-eye surface has the liquid crystal polarizing panel 130 after passing through the liquid crystal polarizing panel 130. The first-polarization direction. At the sub-frame time T12, the liquid crystal polarizing panel 130 uses the turning of the internal liquid crystal molecules to change the polarization direction of the right eye Φ, so that the right-eye surface has the second after the through-crystal polarizing panel 130. In more detail, the liquid crystal polarizing panel 130 is similar to a general display panel, and has a scanning line and a data line. Therefore, the liquid crystal polarizing panel 130 can receive a control signal by the scanning line and the data line to cause the liquid crystal molecules to turn. It is converted to the first polarization direction at the sub-frame time T11, and is switched to the second polarization direction at the sub-frame time T12, and its action is as shown in FIG. 1 . It is worth mentioning that when the liquid crystal polarizing panel 13 is only When there is a scan line (no configuration data line), as long as the _201024798_w 24870twf.doc/d end of the thin film transistor is connected to the scan line, it can still be based on the control signal. In addition, when the liquid crystal polarizing panel 130 is not provided with a data line, the aperture ratio can be improved, and the display can have a higher display brightness. FIG. 1C is green for the lens of the viewing mirror of FIG. 1A. In Fig. 1C, the sight glass 140 has a left eyeglass lens 141 and a right eyeglass lens 142. The left eyeglass lens 141 is a lens having a third polarization direction, and the right eyeglass lens 142 is a lens having a fourth polarization direction. The spirit of the present invention will now be described with reference to FIGS. 1A to 1c. At the sub-frame time T11, the display module 12 displays the left eye plane, and the liquid crystal polarizing panel 13 turns to the first polarization direction, so that The left eye face is given a first light direction when passing through the liquid crystal polarizing panel 13 . Therefore, when the #first-polarization direction is the same as the third polarization direction and the second polarization direction is in the fourth polarization direction, the left-eye pupil surface can be transmitted to the left of the user through the left-eye lens at the sub-frame time T11. The eye, and because of the first-to-polarization direction and the fourth polarization direction sub-frames T11, the right eye of the four (four) to (four). One in

In addition, at the sub-frame time T12, the display module 120 displays the right eye plane ' while the liquid crystal polarizing panel 130 is turned, and j is switched to the second polarization direction, so that the f-eye surface passes through the liquid crystal polarizing panel 13 () The second polarized light is given to the second, so that the right-eye picture can pass through the right at the T12 of the second and fourth directions when the first-polarization direction is the same as the third polarization direction and the second-bias=^ is opposite to the fourth polarization direction. The spectacle lens is transmitted to the right eye of the user, and the second polarizing direction is different from the third reddish direction, and the right eye screen cannot transmit the left eye of the user at the sub-frame time T12. Therefore, the user sees the left eye 昼 201024798 : 1TW 24870 twf.doc / d face only when the sub-frame time τ 丨 ,, and only the right eye sees the right eye face at the sub-frame time T12. Therefore, according to the visual persistence characteristic of the human eye, the user may feel that the left eye picture and the right eye face are respectively viewed from the left and right eyes at the same time, and the left and right eyes are generated by the left eye face and the right eye face. Parallax' then the user will see a stereo image. It is worth noting here that since the liquid crystal polarizing panel 13A and the display module 120 are both using a liquid crystal panel, there is a liquid crystal molecule reaction time.

problem. In more detail, between adjacent sub-frame times, the liquid crystal docking light panel 13, 0 will perform a switching action (converting from the first polarization direction to the second polarization direction) 'the switching voltage is as shown in FIG. 2 Shown in dotted lines. At this time, the display module 120 also performs a switching action (converted from displaying the left eye face to displaying the right eye face). The gray scale voltage is as shown by the solid line in FIG. Therefore, as can be seen from Fig. 2, when the sub-frame time τιι ends and enters the sub-frame time T12, since the display Chi 12G has not been completely switched, the liquid crystal polarizing panel 13 has been switched (as shown in Fig. 2). At time TD), this situation will cause

When the right eye of the user is at the sub-frame time T12, both the left eye face and the right eye face are simultaneously seen, so that the stereoscopic image effect is deteriorated. In order to solve the problem of the reaction time of the liquid crystal molecules described above, the present embodiment is a problem in which the cutting time of the display module 120 and the liquid crystal polarizing panel is not changed. In detail, in this embodiment, the black box surface is inserted in each process, that is, the display module 120 is displayed in the -mi order display black box, the left eye side, the black side, and the right eye. Therefore, in the process of switching, only the black face and the left eye face are seen, while the right eye only sees the black face and the right eye picture, so there will be no same Seeing the left and right sides of the problem appear. For the above-described technique of inserting a black face, it can be realized by using a dynamic backlight or display material added to the black face. For example, when the display 11 is a dynamic back wire as a bolster, the county backlight only needs to turn off the light source during the switching process, that is, turn off the light source at time TD, resulting in the left eye at time TD. The face (because the display module 12〇 has not been completely switched over) will not be displayed, and the light source will be turned on after the time TD. Therefore, when the user ends at the sub-frame time T11 and enters the sub-frame time T12, the right eye will not see both the left eye face and the right eye face at the same time. In addition, when the display of the black-faced display data is used, the method is to add the black-faced surface before the display of the left-eye and right-eye faces. - The black frame, the left eye surface, the black surface, and the right eye surface are sequentially displayed in the frame time, and the gray scale voltage is as shown in Fig. 3 ^ solid line (the solid valley is the gray showing the black surface) Order voltage). Therefore, the display material that participates in the black screen 'will make the face and the left eye face when switching, and the right eye will only see black. It is worth mentioning that the liquid crystal polarizing panel 130 is disposed in the display module ^ display mode The display panel process of the group 120 is performed, for example, by adding a pixel_and a liquid crystal layer to the display (4) of the board. Therefore, when the resolution of the liquid calendering panel 13〇 is the same as that of the display module 12〇, it must be completely corresponding to the interesting 20, otherwise the display mode =, ', no face relief will be blocked due to its And falling. However, the liquid crystal 11 201024798 : 1TW 24870iwf.doc / d polarizing panel 130 7C is used to polarize the display face instead of to display the face. Therefore, when the resolution of the liquid crystal polarizing panel 130 is smaller than that of the display module 120, the resolution of the 11G is not affected; any influence will be exerted, and the transmittance will not be lowered by the lying problem at the opening π. * For the structure of the liquid crystal polarizing panel 130, since the shirt has high resolution and only two kinds of polarization directions are required for the operation, the internal data line and the color light sheet can be omitted. Line LCD polarized panel architecture.

^ This, the liquid crystal polarizing panel 130 lacks the configuration of the data line and the color filter and the light sheet, which will help to improve the transmittance of the display module 12〇. From the other point of view, Figure 4 shows the flow of the figure of the other embodiment of the invention. Before the image of the Rangben Jiashiguan image is displayed, it is necessary to understand that the financial method is toward the display device, so it will be mentioned that the image surface is the multiple faces displayed by the display device: like ί : 二ΐΐί图*4 'First, the face knife shown in the frame time is - the left eye face and the right eye face (step si), where this

, day: between ί 1/60 seconds. Then, in the first-sub-frame time, the first picture is displayed in sequence (the step net 'the towel-sub-frame time is the polarization two tJL; ^ the first-sub-frame time will show the left eye face polarization , having a polarization direction (step S3). The frame time sequentially displays the second black and right eye pictures (step s4), wherein the second sub-frame time is 1/12 〇 seconds. In the second sub-frame time, the surface will be polarized to have the first material direction (step s5). The right side = the case, the example is to display the left eye and the right eye in a frequency multiplication manner. Face, and the first main face 201024798: 1TW 24870twf.doc/d and the second black face are used to separate the left eye face and the right eye face before the left eye face and the right eye face. The display device is prevented from being degraded when the switching of the face is incomplete (for example, the reaction time of the liquid crystal molecules of the display in the above embodiment). In particular, the step of inserting the black face can be performed by turning off the backlight of the display device or Adding the display data of the black surface to the display surface, and turning off the light source and adding the display material of the black surface Referring to the above embodiment, it will not be described here. Finally, a left-eye lens having a third polarization direction and a right lens having a fourth polarization direction are provided, wherein the third polarization direction and the first polarization* direction Phase, and *four polarization directions are the same as the second polarization direction (step %). Thus, in the first sub-frame time, the left eye picture having the first polarization direction can be more than the left lens provided above. In the second sub-frame time, the right eye face having the second polarization direction can pass through the right eye lens provided above. Therefore, when the left and right eyes of the user respectively wear the left eye lens and the right eye lens provided above. After that, the left eye of the user can see the left eye face in the first sub-frame time (the right eye wears the right eye piece with the fourth polarization direction and the left eye face cannot be seen), and the right eye thereof It can be seen in the second sub-frame time (the left eye is wearing the left lens with the third polarization direction and the left eye is not visible), so the user can Watching a two-dimensional scene, and its principle and The embodiment is similar, and will not be repeated here. As described above, the present invention is to arrange a liquid crystal polarizing panel 3 on the front side of the display module so that the display surface of the display module has different polarization directions, so 1 group can display the left eye face and the right eye as long as the time of one face is displayed. # By using the combination of the liquid crystal plate and the sight glass, the K image can be produced, and the present invention does not have a habit. Knowing the autostereoscopic display technology 13 201024798 -1TW 24870twf.d〇c/d The problem of viewing position and angle is encountered ^ In addition, the polarizing panel used in the present invention does not require the setting of the data line and the color calender. The opening is improved, so the display touch will not reduce the transmittance due to the liquid crystal polarizing surface, and the image display of the (4) domain is still superior in resolution and high brightness. —...: The present disclosure has been disclosed in the preferred embodiment as it is not intended to be used in any of the technical fields of the present invention, and may be modified in some ways without departing from the spirit and scope of the present invention.
