Description

The liquid crystal on silicon optical projection system shown for 3D rendering

Technical field

The present invention relates to field of projection display, are projected in particular to a kind of liquid crystal on silicon shown for 3D rendering System.

Background technology

With the continuous development of shadow casting technique, 3D (3Dimensions, i.e., three-dimensional) technology also more and more ripe and scale Change, has been widely used for the places such as cinema, home theater at present.No with 3D display technology (i.e. stereo display technique) Disconnected development, requirement of the people to 3D display fidelity are also higher and higher.The basic principle of 3D display is that the left eye of people connects with right eye Different images is received, by the superposition of brain, forms stereo display effect, 3D rendering, generally passes through when shooting in order to obtain Two projecting apparatus in left and right shoot right and left eyes image respectively, when user watches 3D videos, wear corresponding anaglyph spectacles so that Images of left and right eyes receives respective image respectively.

In the prior art, user watches 3D videos and generally uses 3D anaglyph spectacles, and 3D anaglyph spectacles generally comprise active With two kinds of passive type, active is active-shutter glasses, passes through being switched fast for left and right spectacle lens so that a certain period is only There is left eye to see left-eye image, another period only has right eye to see eye image, and makes cutting for glasses by synchronous transmitter It changes and image synchronization；Passive glasses generally comprise spectrum Separated type spectacle and polarization separation formula glasses, spectrum separate type The left and right spectacle lens of glasses are coated with the optical filter of different-waveband respectively so that right and left eyes receive the left and right of different spectral component compositions Eye pattern picture, polarization separation formula glasses, left and right spectacle lens can only penetrate the light of a certain polarization state, and both polarization states are different, Generally orthogonal linearly polarized light.It is exactly polarization separation formula technology, LCOS that current 3D display field, which is applied at most, (Liquid Crystal on Silicon, i.e. liquid crystal on silicon) optical projection system is natural polarization light processing optical projection system, therefore As a kind of ideal chose of 3D Projection Displays.

Currently used LCOS projecting apparatus realizes that 3D generally selects two LCOS projecting apparatus, projects different polarization states respectively The image of image, different polarization states is incident on corresponding right and left eyes respectively, to realize 3D.

As shown in Figure 1, the optical projection system can be with 2 two LCOS projecting apparatus of LCOS projecting apparatus 1 and LCOS projecting apparatus, wherein throwing Shadow instrument 1 include light source 101, light relay system 102, the polarizer 103, PBS prisms 104, LCOS chip 105, analyzer 106 and Projection lens 107；Similar, projecting apparatus 2 includes light source 108, light relay system 109, the polarizer 110, PBS prisms 111, LCOS Chip 112, polarization converter 113 and projection lens 114.

Wherein, in projecting apparatus 1,101 be light bulb or LED light source, sends out the red, green, blue of sequential, and system is relayed by light 102 collimation of system, becomes linearly polarized light (such as S light) by the polarizer 103, is reflected to up to LCOS after being incident on PBS prisms 104 Chip 105 is emitted after LCOS chip is modulated, and polarization state becomes P light at this time, after transmiting PBS prisms, by analyzer 106, It is imaged eventually by camera lens 107；Projecting apparatus 2 is similar with optical projection system 1, and different places is polarization converter 113, by PBS The P light of prism outgoing is changed into S light, is imaged finally by camera lens 114.Projecting apparatus 1 and projecting apparatus 2 are emitted P light and S light respectively Image, human eye wear corresponding polarising glass, just one eye eyeball can be made only to receive P light images, in addition one eye mirror only receives S Light image ultimately forms 3D stereo display effects after brain is superimposed.

Using 3D optical projection systems in the prior art, need to be equipped with two LCOS projecting apparatus, occupied space volume and at This is relatively high.Every LCOS projecting apparatus can be one chip LCOS optical projection systems shown in FIG. 1 as above, can also be three-chip type LCOS optical projection systems, as long as ensureing the image of two projecting apparatus outgoing different polarization states.It should be noted that scheming in projection When picture, two projecting apparatus will strictly keep synchronous, no it will cause the entanglement of picture, lose 3D effect.

It can be seen from the above, although 3D optical projection systems in the prior art can realize 3D, occupied space and cost phase To higher, while two projecting apparatus will strictly keep synchronous, there is certain technical difficulty.

For using two projecting apparatus to show the big and of high cost problem of 3D rendering occupied space in the prior art, at present still Effective solution scheme is not proposed.
