The invention relates to a video screen that includes pixels provided with at least one red LED diode, one green LED diode and one blue LED diode, characterized in that the LEDs are arranged in at least one grouping of red LEDs connected in series (nR), at least one grouping of green LEDs connected in series (nG), and at least one grouping of blue LEDs connected in series (nB). Furthermore, in order to provide current to LED groupings of the same color connected in series and to power each LED grouping independently, said video screen includes a first group of sources in which each source supplies only red LEDs, a second group of sources only green LEDs, and a third group of sources only blue LEDs; wherein all the electronics are integrated in an assembly of identical circuits, except for the LED diodes, for controlling the brightness of each LED, driving the sources efficiently and distributing image data. |
