FIELD: physics.
SUBSTANCE: when assembling segments, the positions of the LED modules with the unique identifiers of the LED modules are recorded in the central database, when turned on, the video controller asks the LED segment modules for their unique identifiers, if the positions of the LED modules with such unique identifiers are not in the video controller's memory, these positions are requested from the central database and stored in the memory of the video controller.
EFFECT: providing the possibility to determine the position of the LED modules inside the LED screen during optical data transmission to the LED modules.
