DEVICE FOR DISPLAYING VIDEO ON COMPOSITE LIQUID CRYSTAL SCREEN Russian patent published in 2015 - IPC G09G5/42 H04N3/22 

FIELD: physics.

SUBSTANCE: disclosed device for displaying video on a composite liquid crystal screen, which additionally includes: a LED panel switching and control unit connected to video processors of separate liquid crystal displays, and in the gaps between two separate adjacent liquid crystal screens on the vertical and the horizontal there are LED panels on the surface of the gaps, said panels having three-colour RGB LEDs, the emission of which is directed towards the viewing side of the image of the composite screen, wherein in the gaps on the vertical between two adjacent screens, the number of which is equal to M-1, the video information of the last column of the previous display is displayed, where M is the total number of liquid crystal displays placed on the horizontal, and in the gaps on the horizontal between two adjacent screens, the number of which is equal to N-1, the video information of the last row of the previous display is displayed, where N is the total number of rows on the vertical of horizontally placed liquid crystal displays, and the total number of the three-colour RGB LEDs used in the gaps on the vertical and horizontal is a number m=Y/d and n=X/d, where Y and X denote the linear dimension of the separate liquid crystal screen on the frame (vertical) and row (horizontal), d is the diameter of the separate RGB LED.

EFFECT: high quality of display and comfortability of viewing video on composite liquid crystal screens.
