Technical Field
The utility model relates to an integrated formation of image 3D shows, more specifically says, the utility model relates to an even no integrated formation of image 3D display device that crosstalks of visual angle.
Background
The integrated imaging 3D display technology is a true 3D display technology without any vision-aid device. The technology has the characteristic of being watched by naked eyes, the recording and displaying processes are relatively simple, and the technology can display full-parallax and full-true-color stereo images, and is one of hot spot technologies of 3D display at present. However, crosstalk and viewing angle non-uniformity remain one of the major factors limiting the wide application of integrated imaging 3D displays.
Disclosure of Invention
The utility model provides a crosstalk-free integrated imaging 3D display device with uniform visual angle, as shown in attached figures 1 and 2, which is characterized by comprising a display screen and a rectangular pinhole array; the rectangular pinhole array is arranged in parallel with the display screen and is correspondingly aligned with the display screen; the horizontal aperture width of the pinholes in the rectangular pinhole array iswThe vertical aperture width of the pinholes in the rectangular pinhole arrayvCalculated from the following formula:
（1）
wherein,pthe pitch of the rectangular pinhole from the picture element,gthe distance between the rectangular pinhole array and the display screen,mthe number of rectangular pinholes in the horizontal direction in the rectangular pinhole array,nthe number of rectangular pinholes in the vertical direction in the rectangular pinhole array,lis the viewing distance;
horizontal thickness of rectangular pinhole arrayaAnd vertical thicknessbRespectively as follows:
（2）
（3）
horizontal viewing angle of integrated imaging 3D display deviceθ 1And vertical viewing angleθ 2The following were used:
（4）
the hole wall of a rectangular pinhole in the rectangular pinhole array is a light absorption layer; the display screen is used for displaying the image elements; the light from each picture element can only pass through the pinhole corresponding to that picture element and not through other pinholes, thereby eliminating crosstalk.
Compared with the prior art, the beneficial effects of the utility model are that: the crosstalk-free integrated imaging 3D display device with uniform view angles reasonably sets the horizontal and vertical aperture widths of the rectangular pinhole arrays and the horizontal and vertical thicknesses of the rectangular pinhole arrays, so that light rays passing through each rectangular pinhole only illuminate corresponding image elements, and the horizontal viewing view angle is equal to the vertical viewing view angle; in addition, the hole wall of the rectangular pinhole in the rectangular pinhole array is set to be a light absorption layer, so that light is prevented from reflecting through the hole wall to illuminate other image elements, and therefore crosstalk is thoroughly eliminated.
