FIELD: physics.
SUBSTANCE: proposed method comprises placing strings of with certain number of mini LEDs connected in series in integral field at concentric fields of varying geometry. Said integral field is uniformly divided into sections in concentric fields multiple of certain number of mini LCDs to be connected in string of mini LCDs. All strings made are connected in parallel. Finished integrated LED matrix is connected to weak current. Current is set to ensure visual or instrumental determination of the number and configuration of faulty concentric strings and brightness of sound strings. After determination LED matrix permissible current is corrected and type of string is defined.
EFFECT: uniform illumination, higher reliability.
