FIELD: physics.
SUBSTANCE: invention relates to the field of light-emitting diodes, in particular to a light-emitting diode board and a screen using it. LED board comprises front and rear sides of board, where multiple through holes pass through front side of board and back side of board, and multiple through holes comprises at least two rows of through holes. At least every three through holes surround one island-shaped section of the board on the front side of the board, the island-shaped section of the board is equipped with at least two electrode contacts and electrode contacts are made with possibility of connecting light-emitting diodes located on the front side of the board. LEDs are located on the island-shaped section of the board and do not cover the through holes, or one of the LEDs is located above one or more through holes, covers and connects two different island-like sections of the board on two sides or around one or more through holes, and is also connected to two electrode contacts of these island-like sections of the board.
EFFECT: invention provides higher uniformity of distributed display and improved light transmission.
