Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0032] In the prior art, methods for eliminating moiré on LED display screens include:

[0033] 1. Change the camera angle. Since the angle of the camera to the object can cause moiré, changing the angle of the camera slightly (by rotating the camera) can remove or alter any moiré that is present.

[0034] 2. Change the camera position. Also, changing the angular relationship by moving it side to side or up and down can reduce moiré.

[0035] 3. Change focus. Too sharp focus and high detail on fine patterns can cause moiré, changing the focus slightly can change the sharpness and in turn help e...

Abstract

The invention applicable to the field of display and provides and LED (light-emitting diode) module. The LED module comprises LED arrays and a control circuit used for driving the LED arrays to operate; the LED arrays include a plurality of LED units, the LED units of each row include a plurality of LEDs distributed in sequence; the LED arrays are distributed in an interlacing alignment manner, wherein the LEDs identical in sequence in the every two neighboring LED units are not on the same vertical direction, and the structure that the LEDs and the LEDs in the every two neighboring LED unitsare arrayed in a staggered manner is formed in the LED units of each row; the control circuit is used for converting received serial digital signals to parallel display signals, and the LEDs are controlled to be turned on or off through the parallel display signals. The LED arrays are distributed in the interlacing alignment manner, so that when the LEDs are operated, moir cannot be generated whenvarious digital recording equipment is used for photographing and camera shooting, distortion of pictures is avoided, and integrity of picture video information is guaranteed.

Description

technical field [0001] The invention belongs to the field of LED display, and in particular relates to an LED module, an LED display screen and a display system. Background technique [0002] The LED layout of the existing LED display is a typical matrix pattern, such as figure 1 shown. [0003] When using cameras, video recorders and other video recording equipment to shoot the existing LED display screen, due to the spatial interference between the pixel layout of the LED display screen and the pixel layout of the image acquisition sensor of the video recording equipment, such as figure 2 Moiré pattern shown. [0004] The method for eliminating the moiré effect of the LED display screen in the prior art is usually to add a low-pass filter film in front of the LED display screen or in front of the lens of the image acquisition device. Through this method, the high-frequency details in the picture are filtered, so that the LED display array and the image acquisition equi...
