Embodiment 1

[0044] An integrated imaging naked-eye 3D free stereoscopic LED display system provided in this specific embodiment is as follows: figure 1 Shown, comprise: camera array 70, video capture card, computer 91, video controller and naked-eye 3D free stereoscopic LED display screen 100; Camera array 70 is connected with video capture card, and described video capture card can be one or can be many block and is responsible for collecting the video data obtained by the camera array 70, the video capture card is connected with the computer 91, and the computer 91 is connected with the naked-eye 3D autostereoscopic LED display screen 100 through a video controller.

[0045] The camera array 70 includes several identical cameras 71 . The equivalent focal length of the camera 71 is set as f. It should be noted that the camera 71 may be a real camera 71, or it may be through a software such as 3DS MAX (3D Studio Max, often abbreviated as 3ds Max or MAX, is a 3D animation rendering and pr...

Embodiment 2

[0055] In this specific embodiment, in order to increase the viewing angle, it can be as follows Figure 7 As shown, several image units 10 in Embodiment 1 are assembled into a curved LED naked-eye 3D display screen 40 in a curved surface, and the viewing angle at a distance from the curved LED naked-eye 3D display screen 40L is angle 2, and at the angle 2 range, such as Figure 7 In the light path shown by the dotted line, the light emitted by each image unit 10 can be received by the eyes of the viewer. From Figure 7 It can be seen from the figure that the factor that determines the size of the angle 2 is the overlapping area of ​​the light emission angle of the image unit 10 at the edge of the curved surface LED naked-eye 3D display screen 40 at L, and the overlapping area is relative to the curved surface LED naked-eye 3D display screen 40. The opening angle of the 3D display screen 40 is the angle 2 . to combine Figure 6 and Figure 7 , it can be seen that due to ...

Embodiment 3

[0057] In this specific embodiment, in order to increase the viewing angle and save the space occupied by the display screen, each image unit 10 in the second specific embodiment is translated into the same plane with its own tilt angle, and assembled as Figure 8 The naked-eye 3D auto-stereoscopic LED display light board 50 with the pseudo-curved surface is shown. At this time, the integrated imaging naked-eye 3D auto-stereoscopic LED display light board 50 of the pseudo-curved surface appears as a plane, but each image unit 10 in the plane has different sizes and directions. One deflection angle, and the deflection angle size and direction of each image unit 10 correspond to the deflection angle size and direction of each image unit 10 when assembled into a spherical curved screen or arc-shaped curved screen in Embodiment 2.

[0058] At this time, the viewing angle at the distance from the pseudo-curved surface LED naked-eye 3D display screen 50L is angle 3, within the range ...

Abstract

The invention discloses an integral imaging naked eye three-dimensional autostereoscopic LED (light emitting diode) display system and a display screen thereof. The display system comprises a computer, an integral imaging naked eye three-dimensional autostereoscopic LED display screen connected with the computer, and a camera array which is used for acquiring image element array generated by an image element for the computer, wherein the image element array is displayed in the LED display screen through the computer. The LED display screen comprises a plurality of image units which are in array assembly together; the image unit comprises a planoconvex lens, a light blocking membrane arranged at the periphery of the planoconvex lens, and a plurality of LED pixel lamps; one surface of the planoconvex lens is a plane, and the other surface is a convex surface; the LED pixel lamps are arranged on the plane, and the lighting center of the LED pixel lamps is positioned on a focal plane of the planoconvex lens. By the integral imaging naked eye three-dimensional autostereoscopic LED display screen adopting the technical scheme, panorama three-dimensional imaging technology is perfectly combined with the LED display system through integral imaging, a typoscope is unnecessary; the viewing distance is more flexible, and the crosstalk degree is little.

Description

technical field [0001] The present invention relates to the technical field of LED display, in particular to an LED display system, and more specifically to an integrated imaging naked-eye 3D autostereoscopic LED display system with wide viewing angle range, small crosstalk, large viewing distance range and easy assembly , and the integrated imaging naked-eye 3D autostereoscopic LED display included in the system. Background technique [0002] At present, 3D display has gradually entered people's lives. The 3D display products we can see on the market are mainly vision-aided 3D display methods. Glasses, color filter glasses, etc.) send two parallax images to the left and right eyes of the person respectively. According to the principle of parallax, two parallax images are fused by the brain to make people form a 3D stereoscopic feeling. The visual aid 3D display method has the advantages of deep stereoscopic depth and small crosstalk, but it must wear bulky visual aid equi...
