Description

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

Technical field

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

Background technology

Along with the development of shadow casting technique, technology is more ripe and advises for 3D (3Dimensions, i.e. three-dimensional) Modelling, has been widely used for the place such as cinema, home theater at present.Along with 3D Display Technique is (i.e. three-dimensional aobvious Show technology) development, people to 3D display fidelity requirement more and more higher.The ultimate principle that 3D shows The left eye behaved receives different images from right eye, through the superposition of brain, forms stereo display effect, in order to obtain 3D rendering, typically shoots right and left eyes image when shooting respectively by two, left and right projector, watches 3D user and regard Frequently time, corresponding anaglyph spectacles is worn so that images of left and right eyes receives respective image respectively.

In prior art, user watches 3D video and generally uses 3D anaglyph spectacles, and 3D anaglyph spectacles generally comprises master Dynamic formula and passive type two kinds, active be active-shutter glasses, by being switched fast of right and left eyes eyeglass so that The a certain period only has left eye to see left-eye image, and another period only has right eye to see eye image, and is sent out by synchronization Emitter makes switching and the image synchronization of glasses；Passive glasses generally comprises spectrum Separated type spectacle and polarization separation Formula glasses, the right and left eyes eyeglass of spectrum Separated type spectacle is coated with the optical filter of different-waveband respectively so that right and left eyes receives The right and left eyes image of different spectral component compositions, polarization separation formula glasses, right and left eyes eyeglass can only pass through a certain polarization state Light, and both polarization states are different, the most orthogonal line polarized light.Current 3D display field application Most is exactly polarization separation formula technology, and LCOS (Liquid Crystal on Silicon, i.e. liquid crystal on silicon) projects system System processes optical projection system for natural polarized light, therefore becomes a kind of ideal chose of 3D Projection Display.

Currently used LCOS projector realizes 3D and generally selects two LCOS projectors, and projection is different partially respectively The image of polarization state, the image of different polarization states incides the right and left eyes of correspondence respectively, thus realizes 3D.

As it is shown in figure 1, this optical projection system can be with 2 two the LCOS projections of LCOS projector 1 and LCOS projector Instrument, wherein projector 1 includes light source 101, light relay system 102, the polarizer 103, PBS prism 104, LCOS Chip 105, analyzer 106 and projection lens 107；Being similar to, projector 2 includes that light source 108, light relaying is System 109, the polarizer 110, PBS prism 111, LCOS chip 112, polarization converter 113 and projection lens 114。

Wherein, in projector 1,101 is bulb or LED light source, sends the red, green, blue of sequential, passes through Light relay system 102 collimates, and becomes line polarized light (such as S light) by the polarizer 103, incides PBS prism Being reflected to after 104 reach LCOS chip 105, outgoing after LCOS chip is modulated, now polarization state becomes P Light, after transmission PBS prism, through analyzer 106, eventually through camera lens 107 imaging；Projector 2 and projection system System 1 is similar to, and different places is polarization converter 113, and the P light of PBS prism outgoing is changed into S light, Afterwards by camera lens 114 imaging.Projector 1 and projector 2 outgoing P light and the image of S light respectively, human eye wears phase The polarising glass answered, just can make eyes only receive P light image, and other glasses only receive S light image, 3D stereo display effect is ultimately formed after brain superposition.

Use 3D optical projection system of the prior art, need to be equipped with two LCOS projectors, take up room volume with And cost is the highest.Every LCOS projector can be the one chip LCOS optical projection system as shown in figure 1 above, Can also be three-sheet type LCOS optical projection system, as long as ensureing the image of two projector outgoing different polarization states.
