Description
Technical field
Equipment of the present invention and method relate to a kind of large scale three-dimensional display and method of utilizing the circular polarization principle to realize.
Background technology
When eyes are observed object, differ the distance of about 55mm between left eye and the right eye and the binocular parallax that produces, be to produce stereo key factor.Thus, utilize the binocular parallax principle, make eyes see different images respectively, can make the people obtain real stereo perception.At present, there is the three-dimensional display that much utilizes the binocular parallax principle design to come out to obtain using widely, such as military affairs, medical science, building, recreation, video display etc. in a lot of fields.
For making eyes see different images respectively, just need use light splitting technology, promptly allow from the light of the different image emissions of two width of cloth, enter left eye and right eye respectively.In present light splitting technology, mainly comprise the light splitting technology that utilizes liquid crystal shutter and the light splitting technology of polarization theory, that has used wherein that polarization theory carries out beam split has stereo projection technology and a dual screen mirror-image stereo technology, respectively stereo projection technology and dual screen mirror image technology is introduced below:
Stereo projection technology, as Fig. 1, comprising 11a of projector and 11b, polaroid 12a and 12b, metal screen 13, polarising glass 14, direction identical with polaroid 12a and 12b respectively of shaking thoroughly of the eyeglass 14a of polarising glass shown in it 14 and 14b, and the direction of shaking thoroughly of polaroid 12a and 12b is vertical mutually, and before being placed on the camera lens of 11a of projector and 11b respectively, thus, 11a of projector and 11b will be with the orthogonal image projection in two width of cloth polarization directions on metal screens 13, because of metal screen 13 can not destroy the polarization direction of light, so when the observer is with polarising glass 14, eyeglass 14a and 14b will filter out the image of 11b and 11a projection respectively, thereby allow observer's eyes obtain different images, form stereo perception.
Yet there are several like this shortcomings in above-mentioned stereo projection technology: the projection requisite space is big, cost is high, disturbed by extraneous light and move inconvenient.For addressing these problems, developed dual screen mirror-image stereo technology now.Described dual screen mirror-image stereo technology, as Fig. 2, comprise two liquid crystal indicator 21a and 21b, single anti-glass 22, polarising glass 24 and left and right sides eyeglass 24b and 24a, wherein the outermost layer of liquid crystal indicator 21a and 21b all has one deck polarizing coating, its shake thoroughly direction 23a and 23b are in vertical direction with clockwise miter angle, and liquid crystal indicator 21a and 21b vertical placement mutually, single anti-glass 22 is placed on liquid crystal indicator 21a and becomes miter angle with 21b is middle with surface level, the light transmission that wherein single anti-glass 22 can allow liquid crystal indicator 21a launch, and the lower surface of single anti-glass 22 can reflection LCD device 21b emission light, thus, the mirror image virtual image 21c that has liquid crystal indicator 21b is produced, because of virtual image 21c becomes mirror-inverted with liquid crystal indicator 21b, the direction 23c that shakes thoroughly of virtual image 21c also becomes mirror-inverted with the direction 23b that shakes thoroughly of liquid crystal indicator 21b, so the direction of shaking thoroughly 23c is in vertical direction with clockwise 135 degree angles, and the direction 23a that shakes thoroughly of liquid crystal indicator 21a is in vertical direction with clockwise miter angle, and the direction 23c that shakes thoroughly of virtual image 21c is vertical mutually with the direction 23a that shakes thoroughly of liquid crystal indicator 21a thus.The direction of shaking thoroughly of right eyeglass 24a is in vertical direction with clockwise miter angle, the direction of shaking thoroughly of left side eyeglass 24b is in vertical direction with clockwise 135 degree angles, therefore, right eyeglass 24a will be through the light of liquid crystal indicator 21a emission, and filter out the light of virtual image 21c, and left eyeglass 24b will filter out the light of liquid crystal indicator 21a emission through the light of virtual image 21c.When the observer puts on eyes and watches the image of single anti-glass 22 back, right and left eyes will be seen the image that liquid crystal indicator 21a and 21b show respectively, thereby form stereo perception.
Yet there are several like this shortcomings in above-mentioned dual screen mirror-image stereo technology:
1 when putting on observer's angled head of polarising glass, to lose stereo perception, because the eyeglass of polarising glass is a linear polarizer, during angled head, the direction of shaking thoroughly of eyeglass 24a and 24b will no longer be spent angles in vertical direction with clockwise miter angle and 135, thereby lose the function of beam split.
The direction of shaking thoroughly of the liquid crystal indicator that uses in the 2 above-mentioned stereo technologies must become miter angle with vertical direction, and the size of present such liquid crystal indicator is all below 30 inches, and the direction of shaking thoroughly of the liquid crystal indicator more than 30 inches is in vertical direction with 0 degree angle, so the very difficult stereo display that realizes greater than 30 inches of above-mentioned dual screen mirror-image stereo technology.
For addressing these problems, the present invention has realized large scale and high-quality stereo display with very ingenious and simple method on existing display technique.Its advantage: display size is big, the resolution height, and the brightness height, the observer can free angled head.
Summary of the invention
The purpose of this invention is to provide a kind of three-dimensional display, described three-dimensional display has following characteristics: display size is big, resolution is high, can many people watch, not have the fixed view restriction, and the observer can free angled head, makes simple.
