First embodiment

Please refer to FIG. 4A and FIG. 4B simultaneously. FIG. 4A is a schematic diagram of the optical lens group of the three-dimensional image display system receiving the display signal at the first sub-timing according to the preferred embodiment of the present invention; FIG. 4B is a preferred embodiment of the present invention; An optical lens set of a three-dimensional image display system of the embodiment receives a schematic diagram of the display signal at the second sub-timing.

The optical lens group 33a of the present embodiment includes a first polarizing portion 331 and a second polarizing portion 333, and the first polarizing portion 331 has a first polarizing angle P1, and the second polarizing portion 333 has a second polarizing angle P2 polarizing angle. Here, the first polarization angle P1 and the second polarization angle P2 are exemplified by a difference of 90 degrees, but not limited thereto.

The first sub-picture F11 of the first picture and the second sub-picture F12 of the first picture and the first sub-picture F21 of the second picture and the second sub-picture F22 of the second picture respectively pass through the first phase delay zone R1 or After the second phase retardation region R2, respectively, there is a specific deflection angle, and the same polarization portion (for example, the first polarization portion 331 or the second polarization portion 333) can be continuously continuous at the first sub-timing T1 and the second. The sub-timing T2 receives the images of different deflection angles respectively, and the optical lens group 33a can drive the liquid crystal molecules in the first liquid crystal layer L1 and the second liquid crystal layer L2 by using a control unit (not shown) so as to have different deflection angles. The first sub-picture F11 of the first picture and the second sub-picture F12 of the first picture and the first sub-picture F21 of the second picture and the second sub-picture F22 of the second picture can pass through the first polarizing part 331 and the second, respectively. The polarizing portion 333.

For example, at the first sub-timing T1, the first sub-picture F11 of the first picture having the first phase delay amount θ1 passes through the first polarizing portion 331 having the first polarization angle P1, and has the second phase delay. The first sub-picture F21 of the second picture of the quantity θ2 passes through the second polarizing section 333 having the second polarization angle P2. At this time, since the deflection angle of the first screen F1 is perpendicular to the first polarization angle P1, and the deflection angle of the second screen F2 is perpendicular to the second polarization angle P2, in this aspect, the control unit (not shown) It is shown that the first sub-picture F11 of the first picture and the first sub-picture F21 of the second picture can pass through the first polarizer P1, respectively, without driving the liquid crystal molecules in the first liquid crystal layer L1 and the second liquid crystal layer L2. The two polarizing portions P2 are as shown in FIG. 4A.

However, in the second sub-timing T2, since the second sub-picture F12 of the first picture having the second phase delay amount θ2 cannot pass through the first liquid crystal layer L1 having the TN (Twist Nematic) mode, a first polarizing portion 331 having a polarization angle P1, and the second sub-picture F22 of the second screen having the first phase retardation amount θ1 cannot pass through the second liquid crystal layer L2 having the TN (Twist Nematic) mode, and then The second polarizer 333 of the second polarization angle P2 is such that the second sub-screen F12 of the first screen and the second sub-screen F22 of the second screen can enter the first polarizer respectively at the second sub-timing T2. 331, the second polarizing portion 333, the control unit (not shown) of the optical lens group 33a drives the liquid crystal molecules in the first liquid crystal layer L1 and the second liquid crystal layer L2, so that the second phase retardation amount θ2 The second sub-picture F12 of one picture retains the state of the deflection angle parallel to the first polarization angle P1 after the driven first liquid crystal layer L1, and the second picture having the first phase delay amount θ1 The second sub-picture F22 is driven second After crystal layer L2, which remains parallel to the deflection angle in the second polarization state P2 of the angle, shown in Figure 4B.

It should be noted that the behavior of the liquid crystal molecules in the first liquid crystal layer L1 and the second liquid crystal layer L2 (for example, the angle of rotation) of the control unit (not shown) of the embodiment may be selectively synchronized or not synchronized. The time when the first display signal D1 and the second display signal D2 are switched is generated. Of course, the control unit (not shown) can also be used to insert the blank screen or the black screen.

Second embodiment

5A and FIG. 5B, FIG. 5A is a schematic diagram of an optical lens group of another three-dimensional image display system receiving a display signal at a first sub-timing according to a preferred embodiment of the present invention; FIG. An optical lens set of another three-dimensional image display system of the preferred embodiment receives a schematic diagram of the display signal at the second sub-timing.

The optical lens group 33b of the present embodiment is different from the optical lens group 33a in that the first polarization angle P1 of the first polarizing portion 331a in the optical lens group 33b is equivalent to the second polarization angle P2 of the second polarizing portion 333a. Therefore, the fabrication of the optical lens group 33b is relatively simpler than the fabrication of the optical lens group 33a.

In the optical lens group 33b disclosed herein, a first liquid crystal layer L1a having a TN (Twist Nematic) mode is disposed on one side of the first polarizing portion 331a, and a side is disposed on one side of the second polarizing portion 333a. a second liquid crystal layer L2a having a TN (Twist Nematic) mode, wherein the first liquid crystal layer L1a and the second liquid crystal layer L2a are disposed adjacent to each other as an example, and of course, the first liquid crystal layer L1a and the second liquid crystal layer L2a may also be disposed adjacent to each other according to actual needs. For example, the first liquid crystal layer L1a and the second liquid crystal layer L2a may be respectively disposed on different sides of the first polarizing portion 331a and the second polarizing portion 333a, but not used. To limit the invention.

Similar to the above, since the first sub-picture F11 of the first picture and the second sub-picture F12 of the first picture and the first sub-picture F21 of the second picture and the second sub-picture F22 of the second picture respectively pass the first phase After the delay region R1 or the second phase retardation region R2, respectively, there is a specific deflection angle, so that the same polarization portion (for example, the first polarization portion 331a or the second polarization portion 333a) can be at different sub-timings (for example, The first sub-timing T1 and the second sub-timing T2) receive the different deflection angles, and the first liquid crystal layer L1a and the second liquid crystal layer L2a are respectively driven by the control unit (not shown) in the optical lens group 33b. The liquid crystal molecules in the first polarizing portion 331a and the second polarizing portion 333a having the same polarization angle can receive a phase display signal having the same polarization angle as the self-polarized light by the driven liquid crystal molecules.

For example, under the first sub-timing T1, the deflection angle of the first sub-picture F11 of the first picture having the first phase delay amount θ1 is exactly parallel to the first polarization angle P1 of the first polarizing portion 331a, and thus the first The first sub-picture F11 of the screen can be lifted before the liquid crystal molecules of the first liquid crystal layer L1a are driven, and passed through the polarization angle first polarizing portion 331a. However, since the deflection angle of the first sub-picture F21 of the second picture having the second phase delay amount θ2 is not parallel to the second polarization angle P2 of the second polarization portion 333a, control in the optical lens group 33b is possible. The unit (not shown) does not drive the liquid crystal molecules in the second liquid crystal layer L2a (at this time, the liquid crystal molecules in the first liquid crystal layer L1a are driven, so the liquid crystal molecules of the first liquid crystal layer L1a are arranged in the second In the case where the liquid crystal molecules of the liquid crystal layer L2a are arranged differently, the first sub-picture F21 of the second picture having the second phase retardation amount θ2 is passed through the second liquid crystal layer L2a, and the liquid crystal molecules rotated therein are The deflection angle of the second screen F2 is adjusted to be parallel to the second polarization angle P2, so that the first sub-picture F21 of the second picture can pass through the second polarization portion 333a, as shown in FIG. 5A.

In the second sub-timing T2, since the deflection angle of the second sub-picture F22 of the second picture having the first phase delay amount θ1 is exactly parallel to the second polarization angle P2 of the second polarization portion 333a, the second picture is The second sub-picture F22 is lifted before the liquid crystal molecules of the second liquid crystal layer L2a are driven, and passes through the polarization angle second polarizing portion 333a. However, since the deflection angle of the second sub-picture F12 of the first picture having the second phase delay amount θ2 is not parallel to the first polarization angle P1 of the first polarizing portion 331a, control in the optical lens group 33b is possible. The unit (not shown) does not drive the liquid crystal molecules in the first liquid crystal layer L1a (the liquid crystal molecules in the second liquid crystal layer L2a are driven at this time, so the liquid crystal molecules of the second liquid crystal layer L2a are aligned with the first The liquid crystal molecules of the liquid crystal layer L1a are arranged differently, so that after the second sub-picture F12 of the first picture having the second phase retardation amount θ2 passes through the first liquid crystal layer L1a, the first picture can be rotated by the liquid crystal molecules therein. The deflection angle of the second sub-picture F12 is adjusted to be parallel to the first polarization angle P1, so that the second sub-picture F12 of the first picture can pass the polarization angle of the first polarization portion 331a, as shown in FIG. 5B.

Therefore, the first sub-picture F11 of the first picture and the second sub-picture F12 of the first picture, the first sub-picture F21 of the second picture, and the second sub-picture F22 of the second picture are respectively at different sub-timings ( The first sub-timing T1 and the second sub-timing T2) are alternately transmitted through the first display area A1 and the second display area A2 in the display device 31 for display, in other words, for the first picture F1 or the second picture F2. In other words, the resolution represented by the display device 31 is equal to the resolution that can be achieved by the display device 31. Therefore, the resolution of the displayed image is only half of the resolution that the display device 31 can provide. problem.

The first liquid crystal layer (L1 and L1a) and the second liquid crystal layer (L2 and L2a) have the TN (Twist Nematic) mode as an example, but are not intended to limit the present invention, and other alignment modes such as VA (Vertical Align) , IPS (In-Plane Switching), etc. can be used to complete the present invention.

The above is intended to be illustrative only and not limiting. Any equivalent modifications or alterations to the spirit and scope of the invention are intended to be included in the scope of the appended claims.
