Description
Technical Field
The utility model relates to a LED display screen technical field specifically is a display screen mole line subducts device.
Background
In the broadcast television industry, the LED display screen is often applied to various news live broadcasting halls or studio halls, and when a camera in the studio shoots a picture with the LED display screen as a background, the LED display screen may have wave-shaped water ripples in different degrees in the camera and monitor, which are called moire fringes.
Moire generally refers to interference fringes (interferencefringe) generated by superposition of two sinusoidal waves of close frequency and constant amplitude. Moir phenomenon is a visual phenomenon, interference fringes that occur on objects at certain intervals. In an LED screen display image, if a main body in a picture displayed by a screen body has a microgroove texture, a moire color interference phenomenon often occurs, which is a moire phenomenon occurring in an LED full-color screen. Once the moire fringes exist in the image displayed by the LED screen, the color deviation phenomenon can occur, the definition of the image quality is reduced, the image and the playing effect are greatly reduced, and the problems of complex structure, difficult manufacturing and difficult actual operation existing in the moire fringes eliminated by the conventional LED display screen are solved.
