FIELD: physics.SUBSTANCE: four pixels are distributed in each module, wherein corresponding groups of series-connected LEDs have current controllers that are mounted behind the LED groups depending on the colour of the LED in numbers which depend on power requirements of LEDs of three types (R, G and B), thereby enabling independent use of a LED depending on its colour.EFFECT: creating a system current controllers for flexible video screens with independent use of LEDs depending on their colour.8 cl, 3 dwg |
