Please refer to Fig. 4 and Fig. 6, the sequential schematic diagram of the order that Fig. 6 is the control signal RL of explanation in display device 400, the first liquid crystal panel 408 is exported left-eye images and right-eye image, angle, backlight control signal BCS and the bearing signal DS that the second liquid crystal panel 412 rotates.As shown in Figure 6, at period T1, for example, because the first liquid crystal panel 408 is to be a horizontal level (the long limit of the first liquid crystal panel 408 is parallel to surface level), so the bearing signal DS that gravity sensor 402 produces according to the horizontal level of the first liquid crystal panel 408 is noble potential.That is in the time of the horizontal level of the first liquid crystal panel 408, gravity sensor 402, according to the relation between three axles of gravity sensor 402 and gravity direction, produces the bearing signal DS with noble potential.But it is that the long limit of the first liquid crystal panel 408 is parallel to surface level that the present invention is not limited to the horizontal level of the first liquid crystal panel 408, not also being limited to the bearing signal DS that gravity sensor 402 produces according to the horizontal level of the first liquid crystal panel 408 is noble potential.Now, sequential control circuit 404, according to bearing signal DS, determine left-eye images L1 to the first liquid crystal panel 408 in output 3D image, and output has the control signal RL of noble potential.Liquid crystal driver 410, according to the control signal RL with noble potential, is exported a voltage control signal VCS (corresponding to the first voltage V1).Therefore, the liquid crystal in the second liquid crystal panel 412 is for example, to the first angle (135 according to the first voltage V1 rotation
o).At period T2, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore, at period T2, because the second liquid crystal panel 104 is according to the voltage control signal VCS rotation liquid crystal with the first voltage V1, make the left-eye images L1 that penetrated the second liquid crystal panel 104 there is the first angle polarization, and backlight module 406 is according to backlight control signal BCS, open backlight, so observer's left eye can period T2 see through left eyeglass lens 4062 see the left-eye images L1 with the first angle polarization.
In like manner, at period T3, because the first liquid crystal panel 408 is still at horizontal level, so the bearing signal DS that gravity sensor 402 produces is still noble potential.Sequential control circuit 404 is exported right-eye image R1 to the first liquid crystal panel 408 in 3D image, and output has the control signal RL of electronegative potential.Liquid crystal driver 410 is according to the control signal RL with electronegative potential, output voltage control signal VCS (corresponding to second voltage V2).Therefore, the liquid crystal in the second liquid crystal panel 412 is according to second voltage, and rotation for example, to the second angle (45
o).At period T4, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore,, at period T4, the second liquid crystal panel 104, according to the voltage control signal VCS rotation liquid crystal with second voltage, makes the right-eye image R1 that penetrated the second liquid crystal panel 104 have the second angle polarization.So, observer's right eye can be seen at period T4 the right-eye image R1 with the second angle polarization by right eye eyeglass 4064.
As shown in Figure 6, at period T5, for example, because the first liquid crystal panel 408 is to be a upright position (the long limit of the first liquid crystal panel 408 is perpendicular to surface level), so the bearing signal DS that gravity sensor 402 produces according to the upright position of the first liquid crystal panel 408 is electronegative potential.That is gravity sensor 402 is according in the time of the upright position of the first liquid crystal panel 408, the relation between three axles and the gravity direction of gravity sensor 402, produces the bearing signal DS with electronegative potential.But the present invention be not limited to the upright position of the first liquid crystal panel 408 be the long limit of the first liquid crystal panel 408 perpendicular to surface level, not also being limited to the bearing signal DS that gravity sensor 402 produces according to the upright position of the first liquid crystal panel 408 is electronegative potential.Now, sequential control circuit 404, according to bearing signal DS, determine right-eye image R2 to the first liquid crystal panel 408 in output 3D image, and output has the control signal RL of noble potential.Now, storer 414 stores the left-eye images L2 in the 3D image ID that originally should be exported at period T5 to the first liquid crystal panel 408 by sequential control circuit 404.Liquid crystal driver 410, according to the control signal RL with noble potential, is exported a voltage control signal VCS (corresponding to the first voltage V1).Therefore, the liquid crystal in the second liquid crystal panel 412 is according to the first voltage V1, and rotation is to the first angle.At period T6, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore,, at period T6, the second liquid crystal panel 104, according to the voltage control signal VCS rotation liquid crystal with the first voltage V1, makes the right-eye image R2 that penetrated the second liquid crystal panel 104 have the second angle polarization.That is because the first liquid crystal panel 408 rotates 90 from horizontal level
oto upright position, became the right-eye image R2 with the second angle polarization so originally there is the right-eye image R2 (because the second liquid crystal panel 104 is according to voltage control signal VCS rotation liquid crystal to the first angle with the first voltage V1) of the first angle polarization.So, observer's right eye can be seen at period T6 the right-eye image R2 with the second angle polarization by right eye eyeglass 4064.
In like manner, at period T7, storer 414 is exported left-eye images L2 in stored 3D image ID to sequential control circuit 404.Then, sequential control circuit 404 is exported left-eye images L2 to the first liquid crystal panel 408 in 3D image, and output has the control signal RL of electronegative potential.Liquid crystal driver 410 is according to the control signal RL with electronegative potential, output voltage control signal VCS (corresponding to second voltage V2).Therefore, the liquid crystal in the second liquid crystal panel 412 is according to second voltage V2, and rotation is to the second angle.At period T8, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore,, at period T8, the second liquid crystal panel 104, according to the voltage control signal VCS rotation liquid crystal with second voltage V2, makes the left-eye images L2 that penetrated the second liquid crystal panel 104 have the first angle polarization.That is because the first liquid crystal panel 408 rotates 90 from horizontal level
oto upright position, became the left-eye images L2 with the first angle polarization so originally there is the left-eye images L2 (because the second liquid crystal panel 104 is according to voltage control signal VCS rotation liquid crystal to the second angle with second voltage V2) of the second angle polarization.So, observer's left eye can be seen at period T8 the left-eye images L2 with the first angle polarization by left eyeglass lens 4062.
Therefore, as shown in Figure 6, when the first liquid crystal panel 408 is that while being upright position (period T5, T6, T7 and T8), sequential control circuit 404 is by storer 414, the left-eye images in exchange 3D image ID and the output order of right-eye image.So, observer's left eye still can correctly receive the left-eye images in 3D image ID, and observer's right eye still can correctly receive the right-eye image in 3D image ID.But the present invention is not limited to the left-eye images of Fig. 6 and the output of right-eye image order.Therefore, as long as sequential control circuit 404 is by storer 414, left-eye images in exchange 3D image ID and the output order of right-eye image, make observer's left eye still can correctly receive the left-eye images in 3D image ID, and observer's right eye still can correctly receive the right-eye image in 3D image ID, all fall into category of the present invention.
Please refer to Fig. 7, Fig. 7 is that the second embodiment of the present invention illustrates that a gravity sensor 402, a sequential control circuit 404, a backlight module 406, one first liquid crystal panel 408, a liquid crystal driver 410 and coupling of one second liquid crystal panel 412 in a kind of display device 700 of 3D image are related to schematic diagram.As shown in Figure 7, the difference of display device 700 and display device 400 is that display device 700 does not comprise storer 414; Sequential control circuit 404 is to receive a 3D image ID, sequentially export left-eye images and right-eye image in 3D image ID, and according to the sequential of 3D image ID, output one control signal RL, and the output one backlight control signal BCS corresponding to vertical blank interval; Liquid crystal driver 410 is to be coupled to sequential control circuit 404, the bearing signal DS producing in order to reception control signal RL and gravity sensor 402, and according to control signal RL and bearing signal DS, output one voltage control signal VCS; The second liquid crystal panel 412 is to be coupled to liquid crystal driver 410, in order to according to voltage control signal VCS, rotates the liquid crystal in the second liquid crystal panel 412.In addition, the backlight module 406 in display device 700, the first liquid crystal panel 408 and backlight module 406, the first liquid crystal panel 408 and the second liquid crystal panel 412 in the relation that couples of the second liquid crystal panel 412 and the display device 400 of Fig. 4 to couple relation identical.

obearing signal DS, output one voltage control signal VCS (corresponding to one first voltage VP1).Therefore, the liquid crystal in the second liquid crystal panel 412 is according to the first voltage VP1, and rotation is to the first angle.At period T2, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore,, at period T2, the second liquid crystal panel 104, according to the voltage control signal VCS rotation liquid crystal with the first voltage VP1, makes the left-eye images that penetrated the second liquid crystal panel 104 have the first angle polarization.The corresponding angle 0 of the first angle and bearing signal DS
oand be the left eyeglass lens 4162 corresponding to polaroid glasses 416.So, observer's left eye can see that by left eyeglass lens 4062 polarization angle is the first angle and corresponding angle 0 at period T2
oand left-eye images.
In like manner, at period T3, because the first liquid crystal panel 408 is still at horizontal level, so the corresponding angle of the bearing signal DS that gravity sensor 402 produces is still 0
o.Sequential control circuit 404 is exported right-eye image to the first liquid crystal panel 408 in 3D image, and output has the control signal RL of an electronegative potential.Liquid crystal driver 410 is according to having the control signal RL of electronegative potential and having corresponding angle 0
obearing signal DS, output one voltage control signal VCS (corresponding to a second voltage VP2).Therefore, the liquid crystal in the second liquid crystal panel 412 is according to second voltage VP2, and rotation is to the second angle.At period T4, because sequential control circuit 404 is exported the backlight control signal BCS corresponding to the interval VBLANK of vertical blank, so backlight module 406, according to backlight control signal BCS, is opened backlight.Therefore, at period T4, the second liquid crystal panel 104 is according to the voltage control signal VCS with second voltage VP2, and rotation liquid crystal, makes the right-eye image that penetrated the second liquid crystal panel 104 have the second angle polarization.The corresponding angle 0 of the second angle and bearing signal DS
