Naked-eye three-dimensional LED display screen and three-dimensional imaging playing system

Abstract

The invention discloses a naked-eye three-dimensional LED display screen and a three-dimensional imaging playing system. The naked-eye three-dimensional LED display screen comprises a PCB which is provided with first foreground LED beads, second foreground LED beads and background LED beads, the first foreground LED beads and the background LED beads are arranged to form multiple first LED bead columns, the second foreground LED beads and the background LED beads are arranged to form multiple second LED bead columns, and the first LED bead columns and the second LED bead columns are arranged on the PCB to form an LED bead array; the surface of each first LED bead column and the surface of each second LED bead column are each provided with a transparent resin layer unit, the cross sections of the transparent resin layer units are symmetrical in the direction perpendicular to the LED bead array, and the transparent resin layer units are arranged to form a transparent resin layer to cover the LED bead array. Accordingly, videos of the left foreground, the right foreground and the background are displayed in an overlapped mode by setting a light field difference and the prismatic transparent resin layer, and then naked-eye three-dimensional viewing is achieved.

Description

technical field [0001] The invention relates to the field of LED display screens, in particular to a naked-eye three-dimensional LED display screen and a three-dimensional imaging playback system. Background technique [0002] Light-emitting diodes are referred to as LED (Light Emitting Diode), and LED display is a flat-panel display consisting of small LED module panels. [0003] The existing three-dimensional display methods include methods such as fixed grating, chromatic aberration, polarized light, strobe, etc. The method of fixing the grating can not wear glasses, but the fixed grating must require the observer to stand in a narrow angle to watch, and it will still be dazzled for a long time. The method of chromatic aberration requires chromatic aberration glasses. In addition to making the eyes feel uncomfortable with red and blue glasses, the more important thing is that the method of chromatic aberration cannot effectively solve the problem of separation of image in...

Problems solved by technology

[0003] The existing three-dimensional display methods include fixed grating, chromatic aberration, polarized light, strobe and other methods. The method of fixing the grating can not wear glasses, but the fixed grating must require the observer to stand in a narrow angle to watch, and it will still be dazzled for a long time

The method of chromatic aberration requires chromatic aberration glasses. In addition to making the eyes feel uncomfortable with red and blue glasses, the more important thing is that the method of chromatic aberration cannot effectively solve the problem of separation of image information between the two eyes. For example, red glasses can see some blue glasses. The blue glasses can see some images that the red glasses should see, and the brightness of the images seen by the two eyes is very different

The method of polarized light requires polarized glasses, and polarized light has a great influence on the brightness, which will eventually affect the image effect

The stroboscopic method requires wearing stroboscopic glasses to achieve the equivalent of opening and closing the left and right eyes alternately to watch the left and right images, so that people always use one eye to watch the image, so no matter how high the frequency is adjusted to one eye It is said that twice the image information is lost
