Below specify the image display method of the three-dimensional display of Fig. 1.
The 2D display mode
Fig. 3 A is the synoptic diagram of 2D display mode of the three-dimensional display of Fig. 1.Please earlier with reference to Fig. 3 A; When desiring to make said display demonstrate the 2D image; First liquid crystal panel 200 is not bestowed voltage and make liquid crystal layer 206 keep the twisted arrangement state, and second liquid crystal panel 300 is bestowed voltage so that liquid crystal material layer 310 is upright ordered state.In the present embodiment, the liquid crystal layer 206 of above-mentioned first liquid crystal panel 200 and the liquid crystal material layer 310 of second liquid crystal panel 300 are to use twisted nematic formula liquid crystal molecule, and its operating voltage can be 3.3V or 5V.But, the present invention do not limit first liquid crystal panel 200 liquid crystal layer 206 and second liquid crystal panel 300 liquid crystal material layer 310 form with and the operating voltage size.In other embodiments, also can adopt the liquid crystal material of other kinds form and use suitable operating voltage.
At first, display panel 100 sends the light L1 with first polarization direction.In other words, the light that backlight module 110 is sent is through the polarisation of the polaroid 106,108 of display panel 100 and display medium 102 and after reversing, and the light L1 that is penetrated is for having first polarization direction (for example being the polarization direction of parallel directions X).
Afterwards, because the liquid crystal layer 206 in first liquid crystal panel 200 is the twisted arrangement state, so light L1 can be rotated into have second polarization direction light L2 of (for example being the polarization direction of parallel Y direction) after through first liquid crystal panel 200.
Then, because the liquid crystal material layer 310 of second liquid crystal panel 300 is upright ordered state, the light L2 that therefore has second polarization direction still keeps second polarization direction after through second liquid crystal panel 300.
Particularly, because polymeric layer 308 has the alignment direction (directions X orientation) of first direction, and first longitudinal refractive index (no) of the polymer molecule 308a of the refractive index of first lens arrangement 306 and polymeric layer 308 is suitable.Therefore, the light L2 that has second polarization direction does not have the refraction behavior during with polymeric layer 308 at first lens arrangement 306 through second liquid crystal panel 300.In other words, light L2 directly becomes the light L3 with second polarization direction through first lens arrangement 306 with polymeric layer 308.
Afterwards, because the liquid crystal material layer 310 of second liquid crystal panel 300 is upright ordered state, so light L3 still is second polarization direction after through liquid crystal material layer 310.
Then, because polymeric layer 312 has the alignment direction (directions X orientation) of first direction, and first longitudinal refractive index (no) of the polymer molecule 312a of the refractive index of second lens arrangement 314 and polymeric layer 312 is suitable.Therefore, as the light L3 with second polarization direction during at the polymeric layer 312 through second liquid crystal panel 300 and second lens arrangement 314, the light L3 with second polarization direction does not have the refraction behavior equally.In other words, light L3 is directly through can directly passing second liquid crystal panel 300 with light L4 after the polymeric layer 312 and second lens arrangement 314.
In the display mode of Fig. 3 A, owing to light L4 directly passes second liquid crystal panel 300 not have the refraction behavior, thereby this moment, what watched was the image of 2D.

Likewise, display panel 100 sends the light L1 (for example being the polarization direction of parallel directions X) with first polarization direction.
Then, because the liquid crystal layer 206 in first liquid crystal panel 200 is the twisted arrangement state, so light L1 can be rotated into have second polarization direction light L2 of (for example being the polarization direction of parallel Y direction) after through first liquid crystal panel 200.
Then; Because the liquid crystal material layer 310 of second liquid crystal panel 300 also is the twisted arrangement state, the light L2 that therefore has second polarization direction can be reversed into first polarization direction (for example being the polarization direction of parallel directions X) after through second liquid crystal panel 300.
Particularly, because polymeric layer 308 has the alignment direction (directions X orientation) of first direction, and first longitudinal refractive index (no) of the polymer molecule 308a of the refractive index of first lens arrangement 306 and polymeric layer 308 is suitable.Therefore, the light L2 that has second polarization direction does not have the refraction behavior during with polymeric layer 308 at first lens arrangement 306 through second liquid crystal panel 300.In other words, light L2 directly becomes the light L3 with second polarization direction through first lens arrangement 306 with polymeric layer 308.
Afterwards, when the light L3 with second polarization direction when the liquid crystal material layer 310, can be reversed into first polarization direction (for example being the polarization direction of parallel directions X).
Then; Because polymeric layer 312 has the alignment direction (directions X orientation) of first direction; Therefore the light L3 that has first polarization direction can be because second longitudinal refractive index (ne) of the polymer molecule 312a of polymeric layer 312 produces the refraction behavior with the difference of the refractive index of second lens arrangement 314 through the polymeric layer 312 and second lens arrangement 314 time.In other words, light L3 can pass second liquid crystal panel 300 with refracted ray L4 after through the polymeric layer 312 and second lens arrangement 314.
In the display mode of Fig. 3 B, because light L4 passes second liquid crystal panel 300 with refraction bright dipping form, thereby can watch the image of 3D this moment.

Likewise, display panel 100 sends the light L1 (for example being the polarization direction of parallel directions X) with first polarization direction.
Then, because the liquid crystal layer 206 in first liquid crystal panel 200 is upright ordered state, so light L1 still is the light L2 with first polarization direction (for example being the polarization direction of parallel directions X) after through first liquid crystal panel 200.
Afterwards, because the liquid crystal material layer 310 of second liquid crystal panel 300 is the twisted arrangement state, the light L2 that therefore has first polarization direction can be reversed into second polarization direction (for example being the polarization direction of parallel Y direction) after through second liquid crystal panel 300.
Particularly; Because polymeric layer 308 has the alignment direction (directions X orientation) of first direction; Light L2 with first polarization direction can produce the refraction behavior because of the difference of second longitudinal refractive index (ne) of the polymer molecule 308a of the refractive index of first lens arrangement 306 and polymeric layer 308 when first lens arrangement 306 that passes through second liquid crystal panel 300 and polymeric layer 308.In other words, light L2 can form refracted ray L3 after through first lens arrangement 306 and polymeric layer 308.
Afterwards, refracted ray L3 can be reversed into second polarization direction (for example being the polarization direction of parallel Y direction) through liquid crystal material layer 310 time.
Afterwards, because polymeric layer 312 has the alignment direction (directions X orientation) of first direction, and first longitudinal refractive index (no) of the polymer molecule 312a of the refractive index of second lens arrangement 314 and polymeric layer 312 is suitable.Therefore do not have the refraction behavior during at the polymeric layer 312 through second liquid crystal panel 300 and second lens arrangement 314 as refracted ray L3 with second polarization direction.In other words, refracted ray L3 passes second liquid crystal panel 300 with former direct of travel through polymeric layer 312 and second lens arrangement 314 and with former direct of travel, and forms the refracted ray L4 with second polarization direction.
In the display mode of Fig. 3 C, because light L4 passes second liquid crystal panel 300 with refraction bright dipping form, thereby can watch the image of 3D this moment.

Likewise, display panel 100 sends the light L1 (for example being the polarization direction of parallel directions X) with first polarization direction.
Then, because the liquid crystal layer 206 in first liquid crystal panel 200 is the twisted arrangement state, so light L1 can be rotated into have second polarization direction light L2 of (for example being the polarization direction of parallel Y direction) after through first liquid crystal panel 200.
Then; Because the liquid crystal material layer 310 of second liquid crystal panel 300 also is the twisted arrangement state, the light L2 that therefore has second polarization direction can be reversed into first polarization direction (for example being the polarization direction of parallel directions X) after through second liquid crystal panel 300.
Particularly, because first lens arrangement 306 has the orientation (row extends row toward directions X) of first direction, the liquid crystal material layer 310 that therefore fills in first lens arrangement 306 has the alignment direction (directions X orientation) of first direction.In addition, first longitudinal refractive index (no) of the refractive index of first lens arrangement 306 and liquid crystal material layer 310 is suitable.Therefore, the light L2 that has second polarization direction does not have the refraction behavior when filling in the liquid crystal material layer 310 in first lens arrangement 306 at first lens arrangement 306 through second liquid crystal panel 300.In other words, light L2 directly becomes the light L3 with second polarization direction through first lens arrangement 306.
Afterwards, when the light L3 with second polarization direction when the liquid crystal material layer 310, can be reversed into first polarization direction (for example being the polarization direction of parallel directions X).
Then; Because polymeric layer 312 has the alignment direction (directions X orientation) of first direction; Therefore the light L3 that has first polarization direction can be because second longitudinal refractive index (ne) of the polymer molecule 312a of polymeric layer 312 produces the refraction behavior with the difference of the refractive index of second lens arrangement 314 through the polymeric layer 312 and second lens arrangement 314 time.In other words, light L3 can pass second liquid crystal panel 300 with refracted ray L4 after through the polymeric layer 312 and second lens arrangement 314.
In the display mode of Fig. 5 B, because light L4 passes second liquid crystal panel 300 with refraction bright dipping form, thereby can watch the image of 3D this moment.
3D horizontal type (landscape) display mode
Fig. 5 C is the synoptic diagram of 3D horizontal type (landscape) display mode of the three-dimensional display of Fig. 4.Please with reference to Fig. 5 C; When desiring to make said display show the 3D image with 3D horizontal type (landscape) display mode; First liquid crystal panel 200 is bestowed voltage and made liquid crystal layer 206 present upright ordered state, and second liquid crystal panel 300 is not bestowed voltage so that liquid crystal material layer 310 keeps the twisted arrangement state.
Likewise, display panel 100 sends the light L1 (for example being the polarization direction of parallel directions X) with first polarization direction.
Then, because the liquid crystal layer 206 in first liquid crystal panel 200 is upright ordered state, so light L1 still is the light L2 with first polarization direction (for example being the polarization direction of parallel directions X) after through first liquid crystal panel 200.
Afterwards, because the liquid crystal material layer 310 of second liquid crystal panel 300 is the twisted arrangement state, the light L2 that therefore has first polarization direction can be reversed into second polarization direction (for example being the polarization direction of parallel Y direction) after through second liquid crystal panel 300.
Particularly, because first lens arrangement 306 has the orientation (row extends row toward directions X) of first direction, the liquid crystal material layer 310 that therefore is arranged in first lens arrangement 306 also can have the alignment direction (directions X orientation) of first direction.At this moment; Light L2 with first polarization direction can produce the refraction behavior because of the difference of second longitudinal refractive index (ne) of the polymer molecule of the refractive index of first lens arrangement 306 and liquid crystal material layer 310 when passing through first lens arrangement 306 of second liquid crystal panel 300.In other words, light L2 can form refracted ray L3 through after first lens arrangement 306 and the liquid crystal material layer 310 that is positioned at first lens arrangement 306.
Afterwards, refracted ray L3 can be reversed into second polarization direction (for example being the polarization direction of parallel Y direction) through liquid crystal material layer 310 time.
Afterwards, because polymeric layer 312 has the alignment direction (directions X orientation) of first direction, and first longitudinal refractive index (no) of the polymer molecule 312a of the refractive index of second lens arrangement 314 and polymeric layer 312 is suitable.Therefore do not have the refraction behavior during at the polymeric layer 312 through second liquid crystal panel 300 and second lens arrangement 314 as refracted ray L3 with second polarization direction.In other words, refracted ray L3 passes second liquid crystal panel 300 with former direct of travel through polymeric layer 312 and second lens arrangement 314 and with former direct of travel, and forms the refracted ray L4 with second polarization direction.
In the display mode of Fig. 5 C, because light L4 passes second liquid crystal panel 300 with refraction bright dipping form, thereby can watch the image of 3D this moment.
In above-mentioned each embodiment, the top electrode 316 in second liquid crystal panel 300 is between second supporting substrate 318 and second lens arrangement 314, and bottom electrode 304 is between first supporting substrate 302 and first lens arrangement 306.But, the invention is not restricted to this.According to other embodiment, as shown in Figure 6, bottom electrode 304 also can be positioned at the outside surface of first supporting substrate 302, and top electrode 316 can be positioned at the outside surface of second supporting substrate 318.In addition, as shown in Figure 7, bottom electrode 304 can be between first lens arrangement 306 and liquid crystal material layer 310, and top electrode 316 can be between second lens arrangement 314 and liquid crystal material layer 310.
In sum, three-dimensional display of the present invention is because of using the collocation of first liquid crystal panel and second liquid crystal panel, and in the lens combination of second liquid crystal panel, polymeric layer is set.Collocation through said structure can realize that just this display can provide 2D display mode, the straight formula of 3D (portrait) display mode and three kinds of display modes of 3D horizontal type (landscape) display mode.
