The invention belongs to the technical field of LED display screens, discloses an LED display screen moire pattern eliminating method and provides an LED display screen. The front surface of the LED display is provided with a plurality of LED lamp beads arranged at intervals; a light-transmitting film is arranged on the front surface of the LED display screen right opposite the front surface of the LED display screen; a grid structure for light of the LED lamp beads to penetrate is arranged in the LED display screen, and the coverage of the grid structure is larger than that of the LED lamp beads. Due to the fact that the grid structure of the light-transmitting film is utilized, the grid structure can be used for damaging periodicity of the plurality of LED lamp beads on the LED display screen, further spatial frequency of the plurality of LED lamp beads on the LED display screen can be damaged and the condition for producing moire patterns can be eliminated, but an original direction of propagation of the light of the LED lamp beads cannot be damaged, therefore, the sharpness of displayed frames cannot be reduced, hazy problems can be avoided, and the shot frames through a camera are relatively distinct and facilitate watching; besides, the LED display screen moire pattern eliminating structure is simple in structure and easy to operate and achieve.
Description
technical field [0001] The invention relates to the technical field of LED display screens, in particular to an LED display screen anti-moiré structure and a method thereof. Background technique [0002] When video cameras or cameras shoot LED displays, wavy stripes and strange colors often appear, which is often called moiré. The appearance of moiré is a difficult problem faced by TV stations when they use cameras to shoot LED displays. [0003] To eliminate moiré, the resolution of the periodic object to be photographed in the CCD photosensitive element should be much greater than the inherent resolution of the CCD photosensitive element. Similar stripes will not produce moiré. For example, when we shoot an LED display, under the same shooting conditions such as shooting distance and camera focus position, an LED display with a small dot pitch is less prone to moiré than an LED display with a large dot pitch. [0004] In the prior art, to eliminate the phenomenon of moir...
