Abstract (en)

[origin: EP2713357A1] Summary: Comprises pixels including at least one red LED diode, one green LED diode and one blue LED diode, characterised in that the LEDs are organised into at least one red LED (n R ) series circuit, at least one green LED (n G ) series circuit and at least one blue LED (n B ) series circuit, and comprises, in order to supply current to circuits of LEDs of the same colour connected in series and to make their consumption independent, a first group of sources where each source solely supplies red LEDs, a second group of sources to supply green LEDs and a third group of sources to supply blue LEDS; all of the electronics being integrated into a set of identical circuits with the exception of the LED diodes in order to control the brightness of each LED, efficiently manage the sources and distribute image data.
