The integrated imaging 3D display has the defects of narrow viewing angle and the like. Crosstalk is one of the factors that limit the wide application of integrated imaging 3D displays.
Disclosure of Invention
The utility model provides an integrated formation of image 3D display device of no crosstalk and wide visual angle, as shown in figure 1, including pointolite array, display screen and baffler array. The display screen is used for displaying the micro-image array. The display screen is arranged in parallel right in front of the point light source array. The center of the point light source array is correspondingly aligned with the center of the display screen. The barrier array consists of a series of opaque barriers. The barrier array is located between the array of point light sources and the display screen. The point light source array is formed by arranging a plurality of point light sources with the same parameters at intervals, and the micro-image array is formed by closely arranging a plurality of image elements with the same parameters. As shown in fig. 2 and 3, the pitch of the point light sources is larger than the pitch of the image elements, so that the imaging areas of each image element coincide at the optimal viewing distance, thereby realizing a wide-viewing-angle integrated imaging 3D display. In the barrier array, one end of the barrier is fixed between two adjacent image elements, and the length of the barrier is equal to the distance between the point light source array and the display screen; each point light source illuminates the image element corresponding to the point light source and each point light source cannot illuminate the other image elements, thereby eliminating crosstalk.
