Description
Technical field
The present invention relates to the stereo display technique field, relate in particular to a kind of 3 d display device.
Background technology
Development along with Display Technique, people can not be satisfied with two dimension (Two Dimensions, plane display image 2D), (Three Dimensions, 3 d display device 3D) provide information depth perception, more comprehensive but need three-dimensional.The basic principle of three-dimensional imaging comprises:
There is certain distance between left eye and the right eye, therefore two viewing angle is slightly different when watching scenery, the difference of this viewing angle makes left eye see that left image, right eye see right image, left side image and right image are inequality, after brain is synthetic, will produce stereo perception, reach the purpose of viewing and admiring the 3 D stereo display image.
The scheme of 3 D stereo display image is viewed and admired in existing realization, comprising:
One, people at first shoot to same scenery simultaneously with two apish left eyes of video camera and right eye, then two films are shown on a screen synchronously, this moment, the beholder need wear a polarised light glasses, just can view and admire the 3 D stereo display image;
Two, the beholder has worn shutter glasses, when left 3 D stereo display image is scanned on the screen that comes across display, control shutter glasses left side electronic liquid-crystal shutters is that left eyeglass is an opening, the right electronic liquid-crystal shutters of shutter glasses is that right eyeglass is a closed condition, otherwise, when right 3 D stereo display image is scanned on the screen that comes across display, the right electronic liquid-crystal shutters of control shutter glasses is that right eyeglass is an opening, shutter glasses left side electronic liquid-crystal shutters is that left eyeglass is a closed condition, thereby make the beholder can see a left side or right 3 D stereo display image, reach the purpose of viewing and admiring the 3 D stereo display image;
Three, allow the beholder wear the glasses of helmet-type, the left eyeglass of these glasses and right eyeglass respectively are miniscopes, left side eyeglass projection left-eye image, therefore right eyeglass projection eye image can make the people feel to have among the relief virtual environment as entering one.
In sum, existing 3 d display device does not possess the 3 D stereo display image that can show Glassless in vertical direction, the function that also can show the 3 D stereo display image of Glassless in the horizontal direction can't realize that the beholder can reach the purpose of viewing and admiring the 3 D stereo display image by bore hole.
