Compared with prior art, the invention has the advantages of simple manufacture, low cost and good projection effect.
Description
Technical field
The present invention relates to the 3 D stereo field of projection display, particularly relate to a kind of logical colour wheel device of band that is used for the 3 D stereo Projection Display.
Background technology
At present, the main flow stereo projection technology of putting into commercial operation can be divided three classes: active three-dimensional display system, passive polarization three-dimensional display system and spectral separation three-dimensional display system.
Initiatively three-dimensional is that projector about 120Hz alternately exports the right and left eyes picture with a refresh rate, the separation that the LCD anaglyph spectacles that cooperation can left and right sides alternation switch switches the realization left-and right-eye images synchronously, and stereoeffect is fine.But initiatively the anaglyph spectacles cost is higher, and the frequent switch flicker meeting of anaglyph spectacles brings discomfort to eyes, and light is also very big by luminance loss behind the crystal glasses sheet.
Passive polarization stereoprojection is based on the polarization state of light principle, with direction of vibration mutually the two bundle polarized lights of vertical (or the circularly polarized light direction is opposite) two width of cloth image projection to screen, watch with two vertical polarized lenses of printing opacity direction again, two eyes will be seen different images, thereby obtain stereoscopic picture plane.Polarization stereoprojection is very high except the polarizability requirement to screen, also has serious light loss problem in projection process, requires the gain of screen higher.In addition, the metal curtain of polarization stereoprojection employing exists serious solar effect and metal glare problem.
Many bandpass filters that spectral separation stereo display utilization is installed in behind the light source or camera lens is preceding carry out spectrum to be cut apart, and left-and right-eye images is separated, and forms stereoprojection.This technology can be used common screen, cooperates special eyeglasses, and cost is not high.But the light loss of present spectral unmixing technology is bigger, and color is cut apart balance and accuracy requirement is higher, otherwise can cause three-dimensional discrimination inconsistent.On the other hand, the cost of manufacture of the good many bandpass filters of optical property is also very high.
Summary of the invention
Technical matters to be solved by this invention is exactly to provide a kind of logical colour wheel device of band that is used for the 3 D stereo Projection Display for the defective that overcomes above-mentioned prior art existence.
Purpose of the present invention can be achieved through the following technical solutions: a kind of logical colour wheel device of band that is used for the 3 D stereo Projection Display, it is characterized in that, comprise that two can all be inlaid with at least one R colour band pass filter, G colour band pass filter and B colour band pass filter around the center rotary color wheel on each colour wheel.
All be inlaid with a R colour band pass filter, a G colour band pass filter and a B colour band pass filter on described two colour wheels.
All be inlaid with two R colour band pass filters, two G colour band pass filters and two B colour band pass filters on described two colour wheels.
The logical wave band of the band of the bandpass filter on described two colour wheels is a complementary relationship.
Compared with prior art, the present invention has the following advantages:
A. because every group of two projector adopt the logical combination colour wheel that filters of single band respectively, rather than the many band pass filters of a slice in the past, reduced the manufacture difficulty of filter plate greatly, reduced cost;
B. owing to adopt the logical optical filtering colour wheel of single band, the rectangle degree of the logical waveform of band is increased, increased the brightness of stereoprojection picture;
C. owing to adopt the logical optical filtering colour wheel of single band, consistance, the accuracy of each logical wave band of band that filters are increased, reduced the color error ratio of stereoprojection picture;
D. owing to adopt the logical optical filtering colour wheel of single band, the logical wave band accuracy of each band is increased, the overlapping wave band of left and right two pictures reduces in one group, has effectively avoided phenomenons such as ghost image of the prior art, ghost.

Embodiment
The present invention will be further described below in conjunction with accompanying drawing.
As Fig. 1, comprise in this enforcement two can be around the center rotary color wheel: colour wheel 1, colour wheel 2 all are inlaid with a R colour band pass filter 3, G colour band pass filter 4 and 5 colour band pass filters 12 on each colour wheel; The logical wave band of the band of the bandpass filter on two colour wheels is a complementary relationship.Putting in order of three bandpass filters can be GRB.
Each colour wheel is divided into three parts, inlays R, G, B bandpass filter respectively, and colour wheel can rotate around its center.In use, colour wheel rotates, and makes irradiation light beam thereon lead to wave band by the band of R, G, B respectively constantly in difference, for the logical colour wheel device of a pair of band, generate the logical light beam of band of R1, G1, B1 cyclic sequence and R2, G2, B2 cyclic sequence respectively, as shown in Figure 3.The logical wave band of this two row band is a complementary relationship, as shown in Figure 4, as light source, can carry out the 3 D stereo Projection Display by the logical light beam sequence of this two row band.
As Fig. 2, present embodiment comprise two can be around the center rotary color wheel: colour wheel 1, colour wheel 2 all are inlaid with two R colour band pass filters 3, two G colour band pass filters 4 and two B colour band pass filters 5 on each colour wheel.Putting in order of six bandpass filters can be GRBGRB.
Each colour wheel is divided into six parts, inlays 2 groups of identical R, G, B bandpass filter respectively, and colour wheel can rotate around its center.In use, colour wheel rotates, and makes irradiation light beam thereon lead to wave band by the band of R, G, B respectively constantly in difference, for the logical colour wheel device of a pair of band, generate the logical light beam of band of R1, G1, B1 cyclic sequence and R2, G2, B2 cyclic sequence respectively, as shown in Figure 3.The logical wave band of this two row band is a complementary relationship, as shown in Figure 4, as light source, can carry out the 3 D stereo Projection Display by the logical light beam sequence of this two row band.With respect to form described in the embodiment 1, present embodiment form colour wheel is handled picture in the unit interval more, reduced the rainbow effect at motion video and edge effectively, and the video dynamic effect is better.Simultaneously, the color of image is abundanter, more gorgeous.
The colour wheel of installing in the present invention and the existing DLP projector is different, be to make the colour wheel not only can colour filter, and further every kind of Color Channel is with logical the optical filtering, make it to form the logical optical filtering wave band of band of left and right complementation, after the logical colour wheel optical filtering of band through a pair of like this rotation, can generate the logical light beam of band of R1, G1, B1 cyclic sequence and R2, G2, B2 cyclic sequence respectively, as shown in Figure 3.As light source, can carry out the 3 D stereo Projection Display by the logical light beam sequence of this two row band.
The color of using the logical colour wheel optical filtering of this band is cut apart the 3 D stereo projection, it is different from existing color and cuts apart three-dimensional stereo display method, the method that employing is cut apart respectively R, G, each band of channles of B, the wave band of generation R1, G1, B1 and R2, G2, two groups of complementations of B2, as shown in Figure 4.
