The sides of the first and second lens modules are used to view the left eye image, and the other of the first and second lens modules are used to view the right eye image. The control circuit is secreted by the first lens module for generating at least the first control signal. [Embodiment] FIG. 1 is a functional block diagram showing an embodiment of a stereoscopic image display system of the present invention. The stereoscopic image display system includes a stereoscopic glasses moving and video display device 104. In the present embodiment, the stereo glasses (1) 2 include, but are limited to, an eyeglass frame (1), a first lens module 112, a second lens module ι4, and a control circuit 116. In this embodiment, the first lens module 112, the second lens module 114, and the control circuit 116 are all disposed on the eyeglass frame lu. The first and second lens modules 112, 114 (for example, the first lens module U2) are used to view the left eye image, 201219837 and the other of the second and second lens modules 112, 114 (for example, the second The lens module 114) is then used to view the right eye image. In addition, the control circuit 116 can output the first and second control signals Sb to S2 to the second and second lens modules 112 and 114, respectively, to control the operations of the first and third lens modules 112 and 114. The stereo _ 102 is available for the user to wear to view the stereoscopic image presented by the video display device 104. For example, in the embodiment shown in FIG. 1, the video display device can be just a liquid crystal display, which includes a display screen (4) such as a liquid crystal display panel and a beta light module, and the backlight module provides a display screen. The desired light source, and the image light output generated through the display screen is controlled via the stereo glasses 1〇2 to control whether the user can enter the left eye or the right eye of the user's stereo image based on the video display device 1〇4, (9) The light output can be linearly polarized light (丨丨·(10) shirt (9)(10)(10) or circularly polarized light (9)—also (5) for example, when the image light output is linearly polarized and the video display device is just When the left eye image and the right eye image are respectively displayed at different time points, the stereo glasses 102 to be matched must have the function of the shutter glasses, and when the image is first output as circularly polarized light and the video display device is set to be displayed at the same time point. For the left-eye image and the right-eye image with different circular polarization directions, the stereo glasses ι〇2 must have the function of polarized glasses. Please note that the video display device 1〇4 It is not limited to a liquid crystal display, that is, the video display device 1〇4 can also be any thin face that can be used together with the stereo glasses 1〇2 to present a stereoscopic image (4), such as an organic light-emitting two shop (〇 ^ 'Wire display, digital light source 201219837 Digital Light Processing (DLP) display / projector, liquid crystal on silicon (LCoS) display technology display / projector, etc. 'In other words, if stereo The glasses 1〇2 are shutter glasses', and the video display device 1〇4 is any display or projector having a specific polarization characteristic (for example, linear polarization characteristic) that can be used with the shutter glasses, and if the stereo glasses 102 are polarized glasses, The video display device 104 is any display or projector that can be used with polarized glasses and has specific polarization characteristics (for example, circular polarization characteristics). Please refer to FIG. 2, and FIG. 2 is the first lens module shown in FIG. A schematic view of a first embodiment of a lens structure of the crucible 12. In this embodiment, the first lens module (eg, the left or right lens) 112 includes, but is not limited to, a first phase retarder element 202, a first polarizer element 2〇4, a first controllable element 206, and a second polarizing element 208. The first polarized light Element 2〇4 has a first fixed polarization direction (eg, 135.), and second polarizing element 2〇8 has a second fixed polarization direction different from the first fixed polarization direction, for example, the second A fixed polarization direction (eg, 45°) is orthogonal to the first fixed polarization direction (eg, 135.). For the first controllable element 206, it selectively changes the polarization of the input light based on the first control signal S1. Direction, for example, the first controllable element 2〇6 is implemented by a TN type (Twisted Nematic)/STN type (Super Twisted Nematic) liquid crystal layer, so the 'first control signal S1 can be an applied control voltage For selectively controlling the rotation of the liquid crystal cell (LC cell) in the liquid crystal layer for the purpose of controlling the polarization direction. 201219837 For example, although the first control signal §1 generated by the control circuit 116 has a first logic level (for example, a low voltage level (ov)), the Zhou Yuli applied to the polarization direction of the input light will be - a preset value (for example, in the present embodiment, the first preset value will be equal to _ 针 疑 90 ) 90 ) 'Because the first polarizing element 2 〇 4 has a first fixed polarization direction Ci 135 135 ) 'so' only The input light having the first-fixed polarization direction reaches the first controllable element through the first-polarized light element 2G4. At this time, the first controllable_reading 206 has no applied control voltage (ie, the control peach U6) Giving a low voltage level (ον) will cause the polarization of the output light to be adjusted to 45. (i.e., (3) 9〇 45 )' is the same as the second fixed polarization direction (for example) of the second polarizing element 2〇8, and passes through the first polarizing element 2〇8. On the other hand, when the first control signal 81 generated by the control circuit 16 has a second logic level (for example, a high voltage level (12V)), the adjustment amount applied to the polarization direction of the input light will be a second preset value (for example, in the present embodiment, the second preset value is 〇., and thus does not change the polarization direction of the input light) 'At this time' the first controllable element 2 〇 6 is applied with a control voltage (ie, the control circuit 116 is given a high voltage level _) to maintain the polarization direction of the input light output equal to the polarization direction of the input light input (ie, 135.), thus orthogonal to the second The second fixed polarization direction (for example, 4y) of the polarizing element 208 cannot pass through the second polarizing element 2〇8. In other words, the control circuit 116 can output the first control signal Μ to the first lens handle set 112 to control the first lens module ii 2 to switch between the open state and the closed state, thereby achieving the purpose of controlling light penetration. However, this is for illustrative purposes only, and is not intended to be a limitation of the present invention. For example, any structure having light penetration control can be used to implement the first controllable element 2〇6, also up to 201219837. The purpose of switching the first lens module 112 between the on state and the off state is controlled. The first phase delay element 2〇2 is used to perform conversion between linearly polarized light and circular polarized light, for example, when the wheeled light is linearly polarized light. The first-phase delay element 2〇2 converts linearly polarized light having a specific polarization direction into left-handed/right-handed circularly polarized light and outputs circularly polarized light, and on the other hand, when the input light is left-handed/right-handed circularly polarized In the case of light, the first phase retardation element of the shell converts the circularly polarized light into linearly polarized light with a specific polarization direction. As shown in Fig. 2, _ "^工丨丁" is called δ and is also attached to the first polarizing element 204. The second polarizing element 208' and the first polarizing element 2'' are disposed between the first smear element 206 and the first phase delay element. In addition, when the stereoscopic glasses view the stereoscopic image presented by the video display device, the first delay element is processed before the first polarizing element 2G4 to process the light produced by the video display device. In other words, the first lens The module 112 needs to face the first phase delay meta card toward the video display device and the second polarizing element toward the user. In a preferred embodiment, the first lens · u2 disk shown in FIG. 2 has the lens structure shown in FIG. 2, and thus includes one piece of _= element and two material elements. And a controllable element, however, in another embodiment, the first lens module m has the lens structure shown in FIG. 2, and the second lens mold (4) 201219837 can adopt any conventional method of making shutter lenses and polarized lenses. The lens change, this design change is also the (4) of the present invention, that is, as long as the lens structure disclosed in the present invention is used in the left eyeglass lens and the right eyeglass lens, it falls within the spirit of the present invention. The scope of the invention. Referring to Fig. 3, Fig. 3 is a schematic view showing a first operation example of the stereo glasses 102 of Fig. 1 used as shutter glasses based on the lens structure shown in Fig. 2. As shown in FIG. 3, the first lens module 112 and the second lens module 114 respectively serve as a left eyeglass lens and a right eyeglass lens, wherein the first lens module 112 includes a first-polarizing element 2〇4 (having a fixing of 135) Polarization direction), first controllable element 2〇6 (clockwise rotation of the polarization direction of the input light by 9〇 based on the first control signal S1 having the first logic level Low), and second polarizing element 208 (having 45. Fixed polarization direction) and first phase delay element 2〇2 (having a phase delay to perform linearly polarized light (4). "35. Conversion with circularly polarized light (counterclockwise left-handed/clockwise right-handed) ). In addition, the second lens module i4 includes a second polarizing element 2H (having a fixed polarization direction of β.), and a second controllable element 216 (maintaining input light based on a second control signal having a second logic level High) The polarization direction), the fourth polarization element is called a fixed polarization direction with W) and the second phase delay t1 212 (having a phase delay to perform linearly polarized light (135. / 45.) and circularly polarized light (counterclockwise a transition between left-handed/clockwise right-handed), wherein the second controllable element 216 is disposed between the third polarizing element 214 and the fourth polarizing element 218, and the third polarizing element 214 is disposed in the second controllable element 216 is between the second phase delay element 212. 11 201219837 As shown in Fig. 3, when the video light output of the video display device 104 shown in Fig. 1 is linearly polarized light (for example, having a polarization direction of 135), the left eye image B will pass the first phase delay. The element 2〇2 and the second phase delay element 212 are respectively converted into right-handed circularly polarized light and left-handed circularly polarized light, and then, since the first polarizing element 2〇4 and the third polarizing element 214 have the same fixed polarization direction. Therefore, the first polarizing element 2〇4 and the third polarizing element 214 allow only 135 of the circularly polarized light. The components of the polarization direction pass.

In the example of using the stereo glasses as the shutter glasses, the control module U6 can actively control the first lens module 112 and the second lens module μ between the open state and the closed state. Continuous switching (that is, the control signal generated by the control circuit S1 will continuously switch between the first logic level and the second logic level), so that the first controllable element 206 constantly changes the input light. In the polarization direction, the second control signal S2 t generated by the control circuit 116 is continuously switched between the first logic level and the second logic level, so that the second controllable element 216 constantly changes the input light.

For example, the reference information may be the timing of the video display device in the output image, and the control circuit 116 may generate the desired first and second control signals 81, S2 based on the reference information from 201219837. In other words, the video display device 104 Only the synchronization signal is provided, and the control settings of when the first lens module 112 and the second lens module 1H are to be turned on or off are not provided, but the control circuit 116 itself is based on the synchronization signal provided by the video display device 1〇4. Controlling when the first lens module (4) 2 and the second lens module 114 are to be turned on or off; in addition, the reference information may directly be the control setting of the lens module 112 and the second lens module 114, and the control circuit is simple Corresponding to the basis of the reference wire (4) _, the second control ship number, please refer to Figure 5 'Fig. 5 is the i-shaped figure of the stereo glasses 1 〇 2 based on the lens structure shown in Figure 2 as one of the polarized glasses Schematic diagram of the operation example. As shown in FIG. 5, the control circuit U6 does not need to add any additional control voltage to the first controllable element and the second controllable element 2\6 at this time. Therefore, the first controllable element 206 and the second controllable element 216 are provided. The polarization direction of the input is rotated clockwise based on the first control signal S1 having the first logic level (for example, 〇v) and the second control signal. As shown in Fig. 5, the video light output of the video display device shown in Fig. i is a circle thief (for example, the left eye shadow has a right-handed circular polarization direction and the right eye image R has a left-handed circular polarization direction). Then, the first phase delay element applies a right-handed circularly polarized light (left eye L) to have 135. Polarization square_hetero-vibration, and converting left-handed 81-polarized light (right-eye image R) into linearly polarized light having a 4y polarization direction, and 'second phase delay element 212' will turn right-handed circularly polarized light (left eye) The image L) is converted to have 45. The linearly polarized light of the polarization direction and the left-handed circularly polarized light (right-eye image R) are observed to have 135. Linearly polarized light. Then, since the first polarizing element 204 and the third polarizing element 214 have the same fixed polarization direction, the first 201219837 2 element 2G4 and the third polarizing tree 214 are only allowed to have i35. The line direction of the polarization direction passes, so that the first-polarizing element 2() 4 outputs a left-eye image [, and the third polarizing element 2U outputs a right-eye image R. Since the second polarizing element view and the fourth polarizer=8 have a __polarization direction, and the first control signal (4) and the second control core 2 both have a first logic level L〇w, the second polarizing element The second and fourth light elements 218 will finally output the left eye image [and the right eye image r to the user's left and right eyes, respectively. In the above, for the example in which the stereo glasses 1〇2 are used as polarized glasses, the control circuit 116 can be applied to the first lens module ιΐ2 and the second lens without applying any control voltage (for example, 12V). The first control signal (4) generated by the control circuit 116 is maintained at a logic level (e.g., 〇ν) such that the first controllable carrier 2G6 maintains the polarization direction of the input light. Similarly, the control circuit 116 generates the same The second control signal is maintained at a logic level (eg, GV) such that the second controllable element 2i6 maintains the polarization direction of the input light), thereby allowing the user's left eye to only see the left eye image and the right eye. I will only see the effect of the right eye image R 'into the stereo image. π is referred to in Fig. 6. Fig. 6 is a view showing a second embodiment of the lens structure of the first lens module 112 shown in Fig. 1. In this embodiment, the first lens module (eg, the left or right lens) 112 includes, but is not limited to, a first controllable element 6〇2, a first polarizing element 604, and a first A phase delay element 6〇6. The functions and operations of the first controllable element 602, the first-polarizing element 604, and the first phase delay element 6〇6 are similar to the first controllable, second polarizing element 2〇8 15 201219837 shown in FIG. 2 and The first phase delay element 202 is not described here. In this embodiment, the first lens module 112 has only a single polarizing element, and the first optical element 604 is disposed between the first controllable element and the first-phase delay element 606. The stereoscopic image of the video display device can have two states of use. In the first state of use, the device can process the video display device before the first polarizing element 6G4. The generated image output light, in other words, the first lens module ιΐ2 needs to face the first controllable element 6〇2 toward the video display device (that is, in Fig. 6, the image light output will be located in the first lens mode) Above the group 112; another aspect, in the second use:: display: the delay element 606 is processed before the first polarizing element 604 to process the ship _ transposed (4) stray light, in other words, the first = 吏The w-phase element (four) 6 is used to purchase (i.e., in the figure, the image light output is located below the first lens module 112).

As shown in FIG. 7, the first lens module 112 and the second lens module 114 respectively serve as a left eyeglass lens and a right eyeglass lens, wherein the first lens module 112 & includes the first controllable component (based on having the first The __ control rib of the logic level Lgw rotates the polarization direction of the input light clockwise by 90.), the first polarizing element 6〇4 (having a fixed polarization direction of 45) • and *the delay element 6 〇6 (having a phase delay to perform the conversion between linearly polarized light (4) heart) and circularly polarized light (counterclockwise left-handed/clockwise right-handed). In addition, the second lens module 114 includes a second controllable element 612 (maintaining the polarization direction of the input light based on the second control signal S2 having the second logic level High), and a second polarization element 614 (having a fixed polarization of 45) Direction) and a second phase delay element (having a +phase phase delay to perform linearly polarized light (10). /45.) and circularly polarized light (counterclockwise left-handed/clockwise right-handed)), where The second lens module (1) includes only a single-polarized light τ piece' and the second polarizing element 614 is disposed between the second controllable element M2 and the fish t-th phase delay element 616. As shown in FIG. 7, when the video light output of the video display device 104 shown in FIG. 1 is linearly polarized light (for example, having a polarization direction of 135), the first control signal 31 and the second control signal are %. Each has a first logic level L〇W (eg, GV) and a second logic level High (eg, 12V), so the left eye image L will pass through the first controllable element 6〇2 and the second controllable element (10), respectively. The linearly polarized light having a polarization direction of =45° and the linear polarization of the polarization direction of Nashang County are followed by 'the same as the first polarizing element_ and the second polarizing element'. 201219837 = polarization direction ^ only c. Offset: the output of the control element 6〇2 passes through the output of the first polarizing element core 612 and cannot pass the second polarized light 鲁: 606: = (linearly polarized light having a 45 polarization direction) through the first phase retarding element =1=Fig. 8 is a schematic diagram showing the second operation example of the stereo glasses 102 of Fig. 1 based on the lens configuration shown in Fig. 6 as a shutter glasses. If the image light output of the video display device 104 shown in the second figure is linearly polarized (for example, having a polarization direction of 135), the right eye image R will pass through the controllable 7C device 6 respectively. 〇2 and the second controllable element 012 are linearly polarized light that still maintains the original polarization direction and linearly polarized light having a polarization direction of 45. Then, since the first polarizing element_ has the same same as the second silk element 6M The polarization direction is fixed and only 45 is allowed. The component of the polarization direction passes, so that only the output of the second controllable element (10) passes through the second polarization reading 614, while the output of the first controllable element _ cannot pass through the first polarization element. 604. Finally, the output of the second polarizing element 614 (and the linearly polarized light having a 45° polarization direction) is transmitted through the second phase delay element 616 to the right-handed circularly polarized light, thereby transmitting the right-eye image R to the user. In view of the above, for the stereo glasses 1 2 as an example of the use of the shutter glasses, the control circuit 116 can actively control the first lens module 112 and the second lens module 114 to be in an open state and a closed state. between § 18 201219837 The first control signal si will continuously switch between the first logic level and the second logic level, so that the first controllable element 6G2 is independent. Changing the polarization direction of the input light, similarly, the second control ship number S2, which is difficult to control the control circuit 116, will be switched to the first logic level and the second logic level to make the second controllable tree 612 Constantly changing the polarization direction of the input light), so that the left eye of the user only sees the left eye image l and the right eye only sees the right eye image ruler, thereby providing a stereoscopic image display effect. See Figure 9, Figure 9 is a schematic view of the stereoscopic glasses 1〇2 of the i-th figure as a biasing mirror based on the lens structure shown in Fig. 6. Note that when the stereo glasses 102 are used as shutter glasses, the first lens The module 112 and the second mirror module 114 will be in the first use state. However, when the stereo glasses 1〇2 are used as polarized glasses, the first lens module 112 and the second lens module and the group 114 will be in the second state. Use the separation, that is, the 'phase-phase delay element _ The second phase delay element 616 will face the video display device ′ while the first controllable element and the second controllable element 612 are facing the user as shown in FIG. 9 , and the control circuit 116 does not need to apply the control voltage to the first Controlling the 7G member 602 and the second controllable element 612, therefore, the first controllable element · ^ controllable element 612 is based on the first HfL number S1 and the second control signal respectively having a first logic level L〇w (for example, (4) S2, the polarization direction of the input light is turned clockwise red by 90 J. The image light output of the video display device _ is circularly polarized (for example, the left eye f; the image L has a left-handed circular polarization direction, the right eye image & The circular polarization direction with the right red - phase delay element - will convert 135 of the right circularly polarized light (right eye image R). The linearly polarized light of the polarization direction and the left-handed circularly polarized light (the left-eye shirt image L) are converted to have β. Linearly polarized light of polarization direction, in addition, 19 201219837 Second phase delay element 616 converts right-handed circularly polarized light (right-eye image R) into linearly polarized light having a 45° polarization direction, and left-handed circularly polarized light (Left eye image L) is converted to have 135. Check the direction of the line optometry. Next, since the first polarizing element_ and the second polarizing element 614 have the same fixed polarization direction, the first polarizing element 6〇4 and the second polarizing element 614 are only allowed to have 45. The linearly polarized light of the polarization direction passes, so that the first-polarizing element 6〇4 outputs the left-eye image L, and the second polarizing element 614 outputs the right-eye image R. Finally, since the first control signal S1 and the second control signal have the first logic level Lqw', the first controllable element and the second controllable element 612 respectively respectively use the first-polarized element_and the second polarized element The output of 614 is rotated clockwise by 9G°' and the left eye image L and the right eye image R are respectively output to the left and right eyes of the user. As described above, for the example in which the stereo glasses 1 2 are used as polarized glasses, the control circuit 116 can be applied to the first lens module ι 2 and the second lens module by the control circuit 116 without applying a control voltage (for example, 12 V). That is, the first control signal si generated by the control circuit 116 is maintained at a logic level (eg, GV), such that the first controllable object maintains the polarization direction of the input light 'samely' by the control circuit 116. The second control signal is maintained at a logic level (such as GV), and the second controllable navigation member 616 is rotated into the polarization direction of the light), so that the left eye of the user only sees the left eye image and The right eye will only see the right eye miscellaneous R' to provide a stereoscopic image display. As shown above, when the stereo glasses 102 are used as shutter glasses based on the lens structure shown in FIG. 6, the first lens module 112 and the second lens module ι 4 need to be at
